Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may determine that a serving base station supports multi-code and single-code transmissions, receiving a scheduling message having a cyclic redundancy check scrambled with a radio network temporary identifier (RNTI), determine resources for communicating with the serving base station based on the scheduling message, and communicate on the resources using coding associated with the single-code transmissions. A base station may identify at least one user equipment that supports single-code transmissions, transmit a scheduling message having a cyclic redundancy check (CRC) scrambled with a radio network temporary identifier (RNTI), wherein the scheduling message schedules the at least one user equipment for communication on resources using coding associated with the single-code transmissions and communicate with the at least one user equipment on the resources using the coding.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a UE capability message indicating support for a dual-base station control resource allocation scheme during a make-before-break (MBB) handover procedure, the dual-base station control resource allocation scheme comprises dividing a maximum number of UE supported control channel monitoring resources between a source base station and a target base station. The UE may identify, based at least in part on the dual-base station control resource allocation scheme, a first set of control channel monitoring resources for the source base station and a second set of control channel monitoring resources for the target base station. The UE may receive, during the MBB handover procedure, control information from the source base station during the first set of control channel monitoring resources and from the target base station during the second set of control channel monitoring resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling that configures a downlink bandwidth for a broadcast channel transmission (e.g., a physical downlink control channel transmission). The UE may determine a bandwidth of the capability is less than the downlink bandwidth, and monitor search space occasions in a period to receive samples of the broadcast channel. The period and the search space occasions may be associated with a control resource set and a search space set. The UE may receive the samples in non-overlapping subbands of the bandwidth according to the bandwidth capability, and detect the broadcast channel based on the samples. The UE may additionally monitor repeated transmission occasions in the period based on detecting the broadcast channel to detect a second broadcast channel (e.g., a physical downlink shared channel).

In some aspects, a user equipment (UE) may receive one or more power saving signals based at least in part on a selected power saving signal configuration of a set of power saving signal configurations, wherein the UE stores information identifying the set of power saving signal configurations; and perform a power saving operation based at least in part on the one or more power saving signals. In some aspects, a base station may determine one or more power saving signal configurations, of a set of power saving signal configurations, to be used to transmit one or more power saving signals; and transmit the one or more power saving signals using the one or more power saving signal configurations. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify physical uplink shared channel (PUSCH) configuration parameters to send a handover completion message at the end of a handover. A source cell may notify the UE of a handover via a handover command and the UE may acquire system information, and in some cases, a downlink message, from a target cell. The UE may identify a waveform configuration, numerology configuration, and/or modulation scheme using information from the handover command message, the system information, and/or the downlink message. The UE may also determine occasions for transmitting a PUSCH. For example, each occasion may include a set of time-frequency resources on which the PUSCH may be transmitted. The UE may send the handover completion message to the target cell via the PUSCH, during the one or more identified occasions, using the identified configuration parameters.

Abstract: Methods, systems, and devices for synchronization signal (SS) block and control resource set (coreset) multiplexing are described. Generally, the described techniques allow a base station to indicate, to a user equipment (UE), the location of a coreset including control information that may be used by the UE. Specifically, a base station may transmit an indication of a coreset configuration and an indication of a type of multiplexing used to multiplex the coreset with an SS block in the SS block to a UE. Accordingly, the UE may receive the SS block, and the UE may determine the location of the coreset based on the coreset configuration and the indication of the type of multiplexing used to multiplex the coreset with the SS block. The UE may then process the control information included in the coreset to identify the location of a data channel including additional system information.

Abstract: Techniques are described herein for mobility procedures configured to maintain connectivity with a device, such as a user equipment (UE), when the UE moves between single-frequency network (SFN) areas. When the UE operates in a radio resource control (RRC) inactive state or an RRC idle state, the UE may utilize hierarchical mobility. As the UE moves throughout the coverage area of the network, the UE may use mobility procedures for moving between a serving radio access network (RAN) notification area (RNA) and a neighboring RNA (e.g., inter-RNA procedures), and/or procedures for moving between SFN areas within the serving RNA (e.g., intra-RNA procedures), which may include procedures for moving between tracking areas (TAs). In some mobility procedures, the UE may skip decoding a system information block. In some mobility procedures, the UE may skip reading the system information. An SFN area may be a radio access network area code (RAN-AC).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may observe control channel monitoring occasions (PMOs) corresponding to different beams configured by a base station. The UE may identify a PMO in a system information window to monitor for downlink control information scheduling a shared channel carrying a system information message. The UE may receive an indication of which synchronization signal/physical broadcast channel (SS/PBCH) blocks are actually transmitted by the base station and determine corresponding PMOs within the system information window. The UE may then monitor for the downlink control channel within the system information window during the corresponding PMOs. The base station and the UE may also implement techniques for system information message repetition within a system information window.

Abstract: Various aspects described herein relate to techniques for mobility mode selection in uplink-based and downlink-based mobility in wireless communications systems. In an aspect, a method for wireless communications may include determining that a user equipment (UE) is operating in a first mobility mode, determining whether the UE satisfies at least one condition associated with mobility of the UE for mobility mode selection, and selecting a second mobility mode based on a determination that the UE satisfies the at least one condition, wherein each of the first mobility mode and the second mobility mode is an uplink mobility mode or a downlink mobility mode. The techniques described herein may apply to different communications technologies, including the 5th Generation (5G) New Radio (NR) communications technology.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify resources associated with a beamformed signal, the identified resources being used by a user equipment (UE) for channel measurements of the beamformed signal, the beamformed signal being one of a plurality of beamformed signals. The base station may generate a signal indicating at least a portion of the identified resources and transmit the signal to the UE. The UE may receive the signal and perform a channel measurement of the beamformed signal using the indicated resources. The UE may transmit, to the base station, a measurement report comprising the channel measurement associated with the beamformed signal.
