Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a set of system information to a user equipment (UE), and the UE may identify an operation mode indicating that the system information is applicable for a plurality cells. When the UE detects that it is in a new cell associated with a second base station, the UE may apply the received system information to establish a communication channel in the new cell associated with the second base station. As such, rather than receiving and decoding new system information upon detection of a new cell/base station, the UE may be able to efficiently apply the known system information to establish a connection in the new cell.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving a random access configuration for the UE, the random access configuration indicating a subcarrier spacing for random access preambles of a random access procedure and a periodicity of slots including random access channel occasions for transmission of the random access preambles, where the periodicity of the slots is based on the subcarrier spacing for the random access preambles, determining a random access radio network temporary identifier based on the periodicity of the slots and a slot index for a slot in which the UE is to transmit a random access preamble, and transmitting, in the slot, the random access preamble indicating the determined random access radio network temporary identifier.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes a method for wireless communications at a base station. The method includes transmitting a message to a number of user equipments (UEs) over a single frequency network channel using a first beam sweep pattern. The method also includes identifying a second beam sweep pattern from a plurality of beam sweep patterns that is different from the first beam sweep pattern for retransmissions of the message. The method further includes transmitting a retransmission of the message to the plurality of UEs over the single frequency network channel using the second beam sweep pattern.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may communicate with a set of transceiver nodes (e.g., transmission reception points (TRPs)) in a first transceiver node operation mode (e.g., a multi-TRP mode). A first transceiver node of the set of transceiver nodes may receive, from a second of the set of transceiver nodes, an indication to switch between rate matching states. The first transceiver node may switch from a first rate matching state to a second rate matching state and may transmit a downlink shared channel based on a resource configuration associated with the second rate matching state. The UE may receive the shared channel based on an antenna port configuration determined by the UE based on the first transceiver node operation and rate matching information. The rate matching information may be provided by the first transceiver node.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently monitoring for wake-up signaling from one or more transmission and reception points (TRPs), the wake-up signaling indicating the presence of data or control information in an on-duration state of a discontinuous reception (DRX) cycle. In particular, select TRPs may be used to transmit wake-up signaling to a user equipment (UE), and the UE may be configured to monitor for wake-up signaling from the select TRPs. Once the UE receives wake-up signaling prior to an on-duration state of a DRX cycle from any of the select TRPs, the UE may then determine the TRPs scheduled to transmit data or control information in the on-duration state (e.g., based on the WUS or based on further control signaling), and the UE may receive the data or control information from the TRPs in the on-duration state.

Abstract: Techniques are provided for managing transmit and receive beams in a millimeter wave (mmW) communication system for use in bistatic radio frequency (RF) sensing. An example method of tracking targets with bistatic radio frequency sensing includes receiving one or more sensing reference signals, generating a signal report based at least in part on the one or more sensing reference signals, transmitting the signal report, receiving tracking signal configuration information, receiving one or more tracking reference signals identified in the tracking signal configuration information, and tracking one or more targets associated with the one or more tracking reference signals.

Abstract: This disclosure provides methods, devices and systems for beamforming in wireless communications. Some implementations more specifically relate to beamforming configurations for multicast communications. A transmitting device may transmit multicast data to multiple receiving devices, concurrently, via a physical downlink shared channel (PDSCH). The PDSCH may be preceded by a physical downlink control channel (PDCCH). The PDCCH may provide scheduling information for the PDSCH, including a multicast beam associated with the PDSCH and a timing offset or delay between the PDCCH and the PDSCH. A receiving device may determine that the PDSCH contains multicast data based on an indication in the PDCCH. To receive the PDSCH, each receiving device may tune its antennas in a direction of the scheduled multicast beam or a default beam based on the delay between the PDCCH and the PDSCH.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a configuration of a set of synchronization signal blocks (SSBs) to be transmitted by a first base station or a second base station. In some cases, the UE may be served by the first base station and the UE may receive, from the first base station or the second base station, a message indicating that a transmission of at least one SSB of the set of SSBs is canceled and indicating resources for a signal (e.g., a reference signal, alternative SSB transmission) to be transmitted by the first base station or the second base station as an alternative to the canceled at least one SSB. The UE may receive, based on the received message from the first base station or the second base station, the signal using the indicated resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a tracking reference signal (TRS) pattern to be used for receiving a TRS. The TRS pattern may indicate a plurality of TRS symbols of the TRS, one or more TRS symbols of the plurality of TRS symbols having a bandwidth that is different than a bandwidth of at least one other TRS symbol of the plurality of TRS symbols, or having a discontinuous tone allocation. The UE may receive the TRS based at least in part on the TRS pattern. Numerous other aspects are provided.
