Abstract: A base station may transmit a beam refinement reference signal prior to a paging physical downlink control channel (PDCCH) monitoring occasion to improve reception of a paging downlink control information (DCI). A user equipment (UE) may receive at least one transmission indicating the beam refinement reference signal transmitted prior to the PDCCH monitoring occasion. The UE may receive the beam refinement reference signal prior to the paging PDCCH monitoring occasion based on the at least one transmission. The UE may receive a downlink control information on the paging PDCCH monitoring occasion based on the beam refinement reference signal.

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, an indication identifying one or more blocked beams that are unavailable to use for uplink or downlink communication. The UE may determine one or more beams to use for communication with the base station based at least in part on the indication identifying the one or more blocked beams. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to a base station providing a user equipment (UE) with a sticky uplink beam assignment for one or more uplink signals. The UE may use the sticky uplink beam assignment for transmission of uplink signals until a new sticky uplink beam assignment is received. In some examples, the sticky uplink beam assignment may include an uplink beam identifier (ID) identifying an uplink beam associated with the transmission of an uplink signal. The uplink beam identified by the uplink beam ID may be used by the UE for transmission of the uplink signal and either all subsequent uplink signals (e.g., physical uplink control channel (PUCCH) and/or physical uplink shared channel (PUSCH)) or subsequent uplink signals of particular uplink channel types (e.g., dynamic PUSCH, configured grant (CG), PUCCH, etc.) until a new uplink beam ID is received. Other aspects, features, and examples are also claimed and described.

Abstract: Aspects described herein relate to communicating a demodulation reference signal (DMRS) corresponding to a downlink control channel, buffering, based on receiving the DMRS, samples of a downlink data channel associated with the downlink control channel, and processing, during on a time period indicated based at least in part on a sequence of the DMRS, at least a portion of the samples of the downlink data channel. Another aspect relates to determining, based at least in part on a sequence of the DMRS, a time offset from the downlink control channel to a downlink data channel, and determining, based at least in part on the time offset, a time period based on which to transmit or start processing samples of the downlink data channel.

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, information indicating a beam switching pattern that indicates beams that are to be used by the UE on a per communication basis in a time domain. The UE may communicate with the base station based at least in part on receiving the information indicating the beam switching pattern. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for mitigating timing resolution limitations due to synchronization signal blocks (SSBs) with low subcarrier spacing (SCS). An example method by a user equipment (UE) generally includes detecting a SSB; determining a start time of a control resource set (CORESET) associated with the detected SSB, wherein the start time of the CORESET is aligned with a boundary of a symbol having a larger cyclic prefix (CP) than one or more other symbols in a same half-subframe; and monitoring the CORESET for a physical downlink control channel (PDCCH) transmission.

Abstract: An apparatus may be configured to determine that a first random access channel (RACH) procedure with a base station is unsuccessful. The apparatus may be further configured to transmit, after determining that the first RACH procedure is unsuccessful, a preamble message for a second RACH procedure with the base station. A second configuration for the second RACH procedure may be different from a first configuration for the first RACH procedure. Another apparatus may be configured to receive a preamble message from a UE for a second RACH procedure having a second configuration different from a first configuration for a first RACH procedure. The other apparatus may be further configured to determine that the first RACH procedure with the UE is unsuccessful.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive configuration information that schedules a search space set; receive, on the search space set, first downlink control information (DCI) that schedules or configures one or more second DCIs that are multiplexed with one or more semi-persistent scheduling occasions; and process the one or more second DCIs based at least in part on the first DCI. Numerous other aspects are provided.
