Abstract: Certain aspects of the present disclosure relate to methods and apparatus for data transmission in synchronization slots. A method for use by a base station for data transmission in synchronization slots includes transmitting a synchronization signal (SS) burst, wherein different SS blocks of the burst are transmitted using different transmit beams and performing frequency division multiplexing (FDM) or time division multiplexing (TDM) to include one or more other types of signals that need to be multicast and are also transmitted using the different transmit beams

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a random access channel (RACH) signature from among one or more RACH signatures associated with a synchronization signal block (SSB). The UE may transmit, to a base station (BS), a RACH communication using the selected RACH signature. Numerous other aspects are provided.

Abstract: This disclosure generally relates to systems, devices, apparatuses, products, and methods for wireless communication. A communication system may include a user equipment (UE) that receives a configuration for contention-free random access (CFRA) and a configuration for contention-based random access (CBRA). The UE determines a first random access resource. The first random access resource maps to one or more beams from a target base station. The UE determines a beam quality associated with the first random access resource. The UE initiates a random access request using the CFRA when the first random access resource is a contention-free resource, and the beam quality of the first random access resource is above a threshold beam quality. The UE initiates the random access request using the CBRA when the first random access resource is the contention-free resource, and the beam quality of the first random access resource is below the threshold beam quality.

Abstract: Aspects described herein relate to receiving multiple synchronization signal block (SSB) signals from a base station, wherein the multiple SSB signals are each beamformed based on a different directional beam, selecting a signature from a signature space of a first SSB of the multiple SSB signals, and transmitting, based on the signature, a random access message to the base station, wherein the random access message includes an indicator of a preferred SSB of the multiple SSB signals.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a first transmit receive point in a multi-TRP configuration, a downlink control information (DCI) communication. The UE may identify one or more quasi-co-location (QCL) relationships associated with a control resource set (CORESET) or a search space set in which the DCI communication is received. A QCL relationship, of the one or more QCL relationships, is associated with one or more physical downlink shared channel (PDSCH) layers that are transmitted from a second TRP in the multi-TRP configuration. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a mapping between a plurality of sets of hybrid automatic repeat request (HARQ) processes and a corresponding plurality of HARQ process types. The UE may configure one or more HARQ processes of the UE based at least in part on the indication. In some aspects, a base station may transmit, to a UE, an indication of a mapping between a plurality of sets of HARQ processes and a corresponding plurality of HARQ process types. The base station may select a HARQ process, of the plurality of HARQ processes, to be used for a communication with the UE based at least in part on the mapping. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for radio link recovery procedure enhancements in wireless communication systems. In some cases, radio link recovery may be enhanced (e.g., sped up and network congestion reduced) by allowing a user equipment (UE) to use an additional secondary cell (SCell) serving the UE to assist in beam recovery when a layer one (L1) event is detected on a primary cell (PCell) or primary secondary cell (PSCell) of the UE.
