Abstract: Aspects of the present disclosure provide techniques for design of channel raster for narrowband operation. One example method, performed by a base station, generally includes determining, based on one or more conditions, an exact frequency location of one channel of one or more channels to perform narrowband communications with a user equipment. The method also includes transmitting an indication of the one or more conditions to the user equipment. The method further includes communicating with the UE, based at least in part on the exact frequency location of the one channel.

Abstract: A method in accordance with aspects of the disclosure comprises receiving a plurality of downlink control information (DCI) signals, wherein each DCI signal is associated with a Demodulation Reference Signal (DMRS) Port Group (DMRS-PG) of a plurality of DMRS-PGs, and each DCI signal within the plurality of DCI signals contains a DMRS-PG Identifier (DMRS-PGID) identifying the associated DMRS-PG, performing one or more measurements associated with the each DCI signal, and generating a multi-port-group uplink control information (UCI) signal based on the one or more measurements associated with the each DCI, wherein the multi-port-group UCI signal contains an indication of whether the each DCI is successfully received. The indication can be explicitly contained in the UCI, or implicitly realized using scrambling sequences associated with DMRS-PGs to scramble the UCI.

Abstract: Certain aspects of the present disclosure provide techniques for layer mapping for multiple transmission reception point (TRP) transmission, for example, for code block group (CBG) based hybrid automatic repeat request (HARQ) acknowledgement feedback in new radio (NR). Aspects of the present disclosure provide a method for wireless communications by a user equipment (UE). The UE receives one or more transport blocks (TBs) from a plurality of TRPs. Each of the one or more TBs comprises a plurality of CBs. For one or more of the plurality of CBs, all bits of the CB are received from a same TRP. The UE decodes the one or more TBs.

Abstract: Certain aspects of the present disclosure provide techniques for adaptive modulo base selection for non-linear precoding. Aspects provide a method for wireless communications that can be performed by a base station (BS). The BS adaptively selects a modulo base for a data stream for at least one user equipment (UE) in a transmission to one or more UEs. The BS selects the modulo base based on one or more parameters. The BS transmits a signal for at least one UE of the one or more UEs to identify the selected modulo base. The BS performs the transmission to the one or more UEs. The UE receives the transmission from the BS and the signal for the identification of the selected modulo base. Based on the signal, the UE determines the modulo base for at least one data stream in the transmission and decodes the data stream using the modulo base.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive or determine information identifying a mapping of one or more codewords with regard to one or more layers, wherein the one or more layers include at least one of: a first set of layers, wherein a fraction of bits associated with each layer, of the first set of layers, is for data associated with the UE, or a second set of layers, wherein all bits associated with each layer, of the second set of layers, are for data associated with the UE; and perform rate matching or decoding based at least in part on the information identifying the mapping. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to wireless communication. In some aspects, a user equipment (UE) may receive an indicator, in a physical downlink control channel (PDCCH) payload, that indicates whether the PDCCH payload includes data or downlink control information (DCI) for obtaining the data, wherein the indicator is an initial state of a cyclic redundancy check that includes a predefined sequence of bits; and obtain at least one of the data or the DCI based at least in part on the indicator. Numerous other aspects are provided.
