Abstract: Apparatus, methods, and computer-readable media for improving uplink data channel repetitions using multiple slot transmit time intervals are disclosed herein. An example method for wireless communication at a user equipment (UE) includes receiving scheduling downlink control information (DCI) indicating, in a time domain resource allocation (TDRA) field, a scaling parameter for a transport block size (TBS) of a physical uplink shared channel (PUSCH) transmission for transmission as PUSCH repetitions over a repetition unit comprising a plurality of single repetitions. The example method also includes transmitting the PUSCH repetitions with scaling based on the scaling parameter indicated in the scheduling DCI.

Abstract: Aspects are provided which allow a UE to apply power-efficient UCI multiplexing rules accounting for situations in which CCs of overlapping PUCCH and PUSCH are in different carrier groups during inter-band CA to result in improved transmission performance. The UE transmits UCI in a PUCCH in a first CC in response to the PUCCH overlapping in time with a PUSCH in a second CC and the first CC being associated with a different carrier group than the second CC. Alternatively, the UE transmits UCI in the PUSCH in the second CC in response to the PUCCH overlapping in time with the PUSCH and the first CC being associated with a same carrier group as the second CC. Furthermore, the UE may apply a diversity scheme for UCI transmissions to achieve improved reliability of UCI feedback. The UE may also indicate which carrier includes UCI based on different DMRS configurations.

Abstract: Aspects of the present disclosure provide apparatuses, methods, processing systems, and computer readable mediums for retransmitting a random access channel (RACH) message, for example, based on parameters for initial RACH transmission. For example, a user equipment (UE) transmits an initial transmission of an uplink RACH message with repetition. The UE receives a downlink control information (DCI) scheduling a retransmission of the uplink RACH message with repetition. The UE determines parameters for the retransmission of the uplink RACH message with repetition based, at least in part, on parameters for the initial transmission of the uplink RACH message with repetition. The UE retransmits the uplink RACH message to the network entity with repetition in accordance with the determined parameters.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication. The techniques include a method wireless communication by a user equipment including receiving a first physical downlink control channel (PDCCH) from a first transmission reception point (TRP) and a second PDCCH from a second TRP, wherein the first PDCCH and the second PDCCH include the same downlink control information (DCI), selecting a physical uplink control channel (PUCCH) resource for transmitting hybrid automatic repeated request acknowledgment (HARQ-ACK) feedback based on one of the first PDCCH or the second PDCCH, and transmitting a PUCCH that includes the HARQ-ACK feedback using the selected PUCCH resource.

Abstract: A configuration that enables a UE to process a PDSCH DMRS bundle having a higher density of DMRS symbols at a beginning of the PDSCH DMRS bundle. The apparatus receives a PDSCH and DMRS in each slot of a plurality of slots, the DMRS being bundled across the plurality of slots, a first subset of slots of the plurality of slots each having a higher DMRS symbol density of DMRS than a second subset of slots of the plurality of slots, the second subset of slots being subsequent to the first subset of slots. The apparatus decodes each received PDSCH based on at least a subset of the received DMRS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of one or more sets of contiguous time domain resources for a multi-slot transmission occasion that spans at least multiple slots. The UE may select, for one or more codeblocks of a communication on the multi-slot transmission occasion, coded bits of a plurality of coded bits on a per slot basis for each of the multiple slots, wherein start locations for bit selection for each of the multiple slots are determined independently from one another. The UE may interleave the coded bits to form one or more interleaved encoded bit sequences of the one or more codeblocks. The UE may transmit the communication including the one or more interleaved encoded bit sequences. Numerous other aspects are described.

Abstract: A UE receives, from a base station or a component of the base station, at least one DL grant after a reception of an UL grant, the at least one DL grant being associated with a DL cDAI value and a DL tDAI value, the UL grant being associated with an UL tDAI value and scheduling a plurality of PUSCH repetitions. The UE calculates a total number of DL grants sent to the UE based on the DL cDAI value. The UE adjusts the total number of DL grants if there is a difference between the total number of DL grants and the UL tDAI value. The UE transmits, to the base station, a HARQ codebook in at least one of the plurality of PUSCH repetitions, a size of the HARQ codebook being based on the adjusted total number of DL grants.
