Abstract: Certain aspects of the present disclosure provide techniques for using subband precoding for uplink transmissions. In some cases, a UE may transmit sounding reference signals (SRS) to a network entity, receive information indicating at least one of a set of one or more frequency domain (FD) bases and linear combination coefficients, determined based on the SRS transmission, determine subband precoding based at least in part on linear combinations of the FD bases based on the linear combination coefficients, and transmit a physical uplink shared channel (PUSCH) with the subband precoding.

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: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for DMRS allocation in sub-band FD. For transmission of UL data in a set of symbols having UL DMRS in at least one symbol, a UE may determine which symbol(s) in a subframe will receive DL DMRS so that the UE may align the transmission of the UL DMRS with a reception of the DL DMRS. For transmission of DL data in a set of symbols having a DL DMRS, a BS may determine for a first subset of symbols that a PUSCH will be received from the UE or determine for a second subset of symbols that a PUSCH will not be received from the UE. The BS insert a DL RS within the first subset of symbols or the second subset of symbols based on the determination regarding the PUSCH.

Abstract: Aspects are provided to support payloads for msgA transmission in a two-step random access (RACH) procedure by providing a one-to-many mapping arrangement between preambles and physical uplink shared channel (PUSCH) resource units (PRUs). A preamble is determined by the UE which is mapped to one or more groups of PRUs to support piggybacking of uplink control information (UCI), frequency hopping on PUSCH, and multiple-slot repetition for msgA transmissions. By piggybacking UCI to a payload in msgA, flexibility may be provided in the selection of MCS and waveform as well as resource allocation for demodulation reference signals (DMRS) and PUSCH in PRUs. Moreover, by allowing a payload to hop to different frequencies on PUSCH during the transmission of msgA, a gain in frequency diversity and interference averaging may be provided, and by enabling a payload to repeat across multiple slots in msgA transmission, coverage enhancement and/or reliability may be increased.

Abstract: Methods, systems, and devices for wireless communications are described. Feedback based codebooks for reducing or eliminating interference between orbital angular momentum (OAM) based backhaul communications between a first network node and a second network node and access communications between the first network node and a user equipment (UE) are described. The first network node may transmit a message to a UE indicating a feedback codebook for a set of reference signals associated with OAM modes. The first network node may transmit the reference signals, where each reference signals may be associated with a respective OAM mode. The UE may generate and indicate in a feedback report to the first network node codewords corresponding to UE feedback for the received reference signals. The first network node may communicate with the UE via an access link and with the second network node via a backhaul link based on the feedback report.

Abstract: Certain aspects of the present disclosure provide techniques for identifying measurement occasions (MOs) to monitor and refrain from monitoring for a repetition of a downlink channel. An example method generally includes determining that, within a monitoring occasion (MO) duration associated with decoding a number of physical downlink control channel (PDCCH) repetitions, the UE should refrain from monitoring at least one MO associated with a first control resource set (CORESET), wherein the MO duration comprises multiple MOs in which the UE is to monitor for repeated PDCCH candidates; refraining from monitoring a first subset of MOs in the MO duration, based on the determination; and monitoring a second subset of MOs within the MO duration.
