Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may identify an energy per resource element (EPRE) ratio between a synchronization signal block (SSB) symbol containing a primary synchronization signal (PSS) and an SSB symbol containing a secondary synchronization signal (SSS), a physical broadcast channel (PBCH), or both, based on an operating band for the UE, a bandwidth of the SSB symbol containing the PSS and the SSB symbol containing the SSB, the PBCH, or both. The EPRE ratio may be based on maximum regulatory equivalent isotropically radiated power (EIRP) limits, maximum regulatory power spectral density (PSD) limits for the band, or both. The EPRE ratios may be different for different SSB symbols, when different SSB symbols have different bandwidths. A base station may configure and transmit, and a UE may receive, the SSB according to the identified EPRE ratio.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, configuration information including multiple transmission configuration indication (TCI) states associated with a control resource set (CORESET). The UE may receive, from the base station, a physical downlink control channel (PDCCH) in a region associated with the CORESET, wherein the PDCCH includes at least one control channel element (CCE). The UE may perform blind decoding for multiple configured PDCCH candidates based at least in part on a resource element group (REG) bundle included in the at least one CCE, wherein the multiple configured PDCCH candidates are associated with one or more of the multiple TC states associated with the CORESET. Accordingly, the UE may identify the PDCCH transmitted by the base station based at least in part on the blind decoding.

Abstract: Methods, systems, and devices for wireless communications are described. A serving cell may configure one or more neighbor cells to perform measurements on sounding reference signals (SRSs) received from a user equipment (UE). The serving cell and a subset of the one or more neighbor cells may then transmit data to the UE in a single frequency network (SFN) transmission based on the SRS measurements. For instance, the serving cell may determine whether to add each of the one or more neighbor cells to an SFN cell group for an SFN transmission to a UE based on measurements performed by each neighbor cell on SRSs received from the UE. A neighbor cell of the one or more neighbor cells may also determine which beam to use for an SFN transmission to a UE based on measurements performed by the neighbor cell on SRSs received from the UE.

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: Example implementations include a method, apparatus and computer-readable medium of wireless communication. A user equipment (UE) may receive a downlink control information (DCI) indicating two or more transmission configuration indication (TCI) states for a physical downlink shared channel (PDSCH). The UE may differentiate that the two or more TCI states apply to all demodulation reference signal (DMRS) ports or all transmission layers across all resource blocks and symbols for the PDSCH from TCI states that apply to different sets of DMRS ports or different sets of resource blocks or symbols. The UE may generate a composite quasi-co-location (QCL) based on the two or more TCI states in response to the differentiating. The UE may receive the PDSCH based on the composite QCL.

Abstract: Methods, systems, and devices for wireless communications are described. A device such as a user equipment (UE) or a base station may identify a beam switching capability of the UE, the beam switching capability indicating a threshold quantity of beam switches during a transmission time interval, a threshold quantity of symbol periods between beam switching operations, or a combination thereof. The device may determine that the beam switching capability of the UE is satisfied based at least in part on one or more parameters (e.g., one or more symbol period durations, one or more quantities of beam switches during a transmission time interval, one or more adjustment parameters, one or more threshold values associated with the capability of the UE, etc.). The device may perform one or more beam switching operations based on determining that the beam switching capability is satisfied.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for performing rate matching when resources for a physical downlink shared channel (PDSCH) overlap with resources of a control resource set (CORESET) in which a physical downlink control channel (PDCCH) that scheduled the PDSCH. As used herein, rate matching generally refers to the process of repeating or puncturing bits on a transport channel.
