Abstract: Fallback procedures for user equipments (UEs) are described that provide efficient fallback to a four-step random access procedure from a two-step random access procedure. For example, after transmitting a first message of a two-step random access procedure, a UE may start a fallback timer or counter and monitor for a second message of the two-step random access procedure for the duration of the fallback timer or counter. At the expiration of the fallback timer or counter, the UE may fall back to a four-step random access procedure. In some cases, the UE may transmit multiple repetitions of the first message and monitor for responses after transmitting the repetitions or after each repetition. Additionally or alternatively, the base station may transmit an explicit signal to the UE that may signal to the UE to perform a fallback procedure at a beginning or middle of a random access procedure.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform a dual active link handover procedure from a source base station to a target base station. During the dual active link handover procedure, the UE may have connections to both of the base stations concurrently. In such cases, transmission opportunities for communicating with the base stations may conflict. To handle conflicting transmission opportunities, the UE may drop a monitoring occasion or a packet reception for a base station based on prioritization rules. In some cases, to mitigate packet losses, the base station may configure re-transmissions or slot aggregation to provide the UE with additional opportunities to receive a packet. Additionally or alternatively, the UE may transmit a notification message to a base station indicating dropped monitoring occasions or packets.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling indicating a set of resources for transmitting a set of uplink shared channel transmissions and a set of demodulation reference signals (DMRSs) having phase coherence across a set of transmission time intervals (TTIs). The UE may receive, from the base station, a control message indicating a cancellation of a first resource of the set of resources. The UE may determine one or more phase-continuity conditions for the set of resources based on receiving the control message indicating the cancellation of the first resource. The UE may transmit, in remaining resources of the set of resources, at least a subset of the set of uplink shared channel transmissions and at least a subset of the set of DMRSs in accordance with the one or more phase-continuity conditions.

Abstract: A method of wireless communication at a transmitting device includes adding parity check bits to a set of information bits. The method also includes generating a non-coherent transmission signal by mapping the parity check bits and the set of information bits into a sequence of complex symbols. Further, the method may include transmitting the non-coherent transmission signal to a receiving device. A method of wireless communication at a receiving device includes receiving, from a transmitting device, a non-coherent signal having at least one segment. Each segment comprises a sequence of complex symbols corresponding to information bits and parity check bits. The method also includes jointly detecting the sequences from each segment of the received non-coherent signal by using the parity check bits.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a first transmit power that is to be used for a first transmission to a source cell and a second transmit power that is to be used for a second transmission to a target cell during a dual-active-protocol stack (DAPS) handover procedure. The UE may transmit, concurrently, the first transmission to the source cell using the first transmit power and the second transmission to the target cell using the second transmit power. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a first message indicating a plurality of measurement configurations, each measurement configuration of the plurality of measurement configurations may include different sets of measurement parameters used for measuring a reference signal (RS) of a cell. The UE may also receive, from the base station, a second message indicating that the UE activate a first measurement configuration, deactivate the first measurement configuration, or switch to the first measurement configuration, where the first measurement configuration is from the plurality of measurement configurations. The UE may determine a measurement reporting scheme based at least in part on the indication to activate, deactivate, or switch to the first measurement configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to monitor, via a receive beam, a first transmission time interval (TTI) of a plurality of different TTIs for a control resource set. The UE may decode the control resource set to obtain a first grant and a second grant. Upon decoding the control resource set, the UE may determine that the first grant and the second grant are associated with different parameters. In some cases, the parameters may be spatial quasi-colocation (QCL) assumptions mapped to the control resource set. The UE may decode, resources of a shared data channel indicated in at least one of the first grant and the second grant. In some cases, the UE may decode the resources during at least one of the first TTI and a second TTI of the plurality different TTIs.

Abstract: In aspects, a base station and a user equipment (UE) exchange synchronization signal blocks (SSBs) carrying a SFN identity, and a waveform of the SSBs has a secondary synchronization signal (SSS) symbol preceding a primary SS symbol. In aspects, a base station transmits a radio access network area code (RAN-AC) SS and RAN-AC page are quasi co-located (QCL). In aspects, a base station transmits a RAN-AC SS over a SFN while avoiding overlap of RAN-AC SS resources with channels employed for initial access of update area cells. In aspects, a base station provides a control resource set (CORESET) to a UE upon release from a connected state, and the UE receives a RAN-AC paging PDCCH based on the CORESET. In aspects, a base station transmits a SFN wake up signal (WUS) when there is a grant for paging, and the UE monitors for the WUS.

Abstract: Methods, systems, and devices for wireless communications are described. A base station determines configuration information for a random access procedure, where the configuration information includes a repetition pattern associated with a first message of the random access procedure. A user equipment (UE) receives, from the base station, a configuration message that indicates the configuration information for the random access procedure. The UE determines a repetition pattern associated with a first message of the random access procedure based on the configuration information. The base station receives, from the UE, multiple instances of the first message based on the repetition pattern.
