Abstract: A base station may determine one or more parameters of a PDSCH group including multiple PDSCHs for each beam in a plurality of beams, configure a plurality of resources for communication via the PDSCH group based on the determined one or more parameters of the PDSCH group, and transmit, to a UE, an indication of at least one parameter of the one or more parameters of the PDSCH group via the plurality of resources. The base station may also transmit, via the plurality of resources, one or more PDSCHs based on the at least one parameter of the one or more parameters of the PDSCH group. The UE may receive the indication of at least one parameter of the PDSCH group including multiple PDSCHs for each beam in a plurality of beams, and receive, from the base station, one or more PDSCHs based on the indication.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for requesting message repetition in random access procedures. In some aspects, a first random access message can be generated for a physical random access channel (PRACH) procedure. The first random access message can include a request for repetition of a third random access message. The request can be based on a criterion that is associated with at least one of a maximum allowed transmit power, or a PRACH transmit power. The first random access message can be output for transmission to a node to initiate a random access procedure with the node. In some aspects, one or more parameters related to a threshold for determining whether to include the request can be configured by the node.

Abstract: This disclosure provides systems, methods, and apparatuses for a wireless node to receive a phase tracking reference signal (PTRS) transmitted inside a downlink random access channel (RACH) message. The wireless node may receive a downlink RACH message that includes a PTRS based on an indication received in a downlink RACH message or a physical downlink control channel (PDCCH) associated with a downlink RACH message. In some aspects, the wireless node may utilize the PTRS for phase error correction or frequency error correction (such as frequency error caused by Doppler effects). This disclosure also provides systems, methods, and apparatuses for a component of a base station to provide an indication that a PTRS is included in a downlink RACH message. The indication may be provided in a downlink RACH message or a PDCCH associated with a downlink RACH message.

Abstract: A base station may transmit at least one configuration of at least one set of one or more TD RS occasions associated with at least one type of reference signal measurement and an indication to dynamically activate or deactivate at least one pattern of the one or more TD RS occasions. A UE may receive one or more TD RS in at least one set of one or more TD RS occasions based on at least one configuration and the one or more of the at least one pattern of the one or more TD RS occasions.

Abstract: Certain aspects of the present disclosure provide techniques for configuring hybrid automatic repeat request (HARQ) soft combining for a subset of HARQ processes supported by a user equipment (UE). A method performed by the UE generally includes transmitting capability information indicating a capability of the UE to perform hybrid automatic repeat request (HARQ) soft combining and receiving, based on the capability information, configuration information from the BS configuring the UE to perform soft combining on only a subset of a set of HARQ processes.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a differential beam pattern indication that indicates beam pattern information corresponding to a comparison between a first synchronization signal block (SSB) beam pattern associated with a first transmit receive point (TRP) and a second SSB beam pattern associated with a second TRP. The UE may receive an SSB associated with the second TRP based at least in part on the differential beam pattern indication. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a user equipment (UE). The UE determines that a scheduled occasion for reporting hybrid automatic repeat request (HARQ) feedback for a first semi-persistently scheduled (SPS) physical downlink shared channel (PDSCH) of a first HARQ process identifier (ID) overlaps with at least one downlink or flexible symbol. The UE reports, defers, or drops the HARQ feedback for the first SPS PDSCH if resources for reporting the HARQ feedback for the first SPS PDSCH are not available until on or after a scheduled occasion for reporting a HARQ feedback for a second PDSCH of the same first HARQ process ID, in response to the determining.

Abstract: This disclosure provides systems, methods and apparatuses for uplink channel transmission for multiple transmit receive points (TRPs). In one aspect, a user equipment (UE) resolves overlapping physical uplink control channels (PUCCHs) in a slot or overlapping PUCCH(s) and PUSCH(s) that are mapped to a same TRP in a multi-TRP scenario and that are mapped to two or more different TRPs in the multi-TRP scenario. For example, in a multi-TRP scenario that includes two TRPs, the UE may eliminate overlap of these uplink channels for each of the two TRPs individually and may additionally eliminate overlap of these uplink channels between the two TRPs.

Abstract: Certain aspects of the present disclosure provide techniques for frequency tracking and timing tracking using wideband reference signals (RSs). A method that may be performed by a user equipment (UE) includes monitoring for a wideband RS from a network entity when one or more conditions are met, the wideband RS occupying a wider band of frequency resources than a tracking reference signal (TRS) transmitted by the network entity; and performing at least one of frequency tracking or timing tracking based on the monitoring.
