Abstract: The present disclosure provides various modifications to existing techniques for transmitting ACK and/or NACK in an narrow band communications system. For example, in a first aspect, an apparatus receives a downlink transmission and transmits a single tone ACK on an ACK channel using time-spreading. In another aspect, an apparatus determines whether an ACK has been received from a UE within a threshold amount of time, and when an ACK has not been received from the UE for at least the threshold amount of time, transmitting an indication to the UE to transmit regarding the ACK

Abstract: Techniques are provided for generating radio frequency (RF) sensing waveforms to enable receiver training in cellular based RF sensing applications. An example method of transmitting a RF sensing signal includes transmitting a first radio frequency signal utilizing a first bandwidth at a first transmit power level, transmitting a second radio frequency signal utilizing a second bandwidth at a second transmit power level, wherein the second bandwidth is larger than the first bandwidth and the second transmit power level is greater than the first transmit power level, and transmitting one or more radio frequency sensing signals utilizing the second bandwidth and the second transmit power level.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may communicate with a second network node using a line-of-sight (LOS) multiple input multiple output (MIMO) configuration at a frequency. The first network node may communicate, based at least in part on a multi-user MIMO (MU MIMO) mode, with a third network node using the LOS MIMO configuration and at the frequency, wherein the MU MIMO mode corresponds to an antenna system configuration of the rectangular antenna array, wherein the antenna system configuration includes at least one of an antenna assignment scheme, an antenna amplitude configuration, or an antenna phase configuration. Numerous other aspects are described.

Abstract: Aspects presented herein may enable an RF sensing node to transmit RF sensing signals based on OFDM symbols that may be flexibly configured, such that OFDM symbols used for RF sensing may be different from OFDM symbols used for communications. In one aspect, an RF sensing node transmits an RF sensing signal in a first time duration of a symbol in an RF sensing session. The RF sensing node monitors for a reflected RS sensing signal in a second time duration of the symbol that does not overlap with the first time duration, the symbol including a CP that does not overlap with the first time duration and the second time duration.

Abstract: Methods, systems, and devices for wireless communications are described in which a base station may identify a null space matrix that lies within a null space of an effective channel matrix for communications between the base station and a user equipment (UE). An indication of the null space matrix may be provided to the UE, and the null space matrix used to determine modifications to a precoding matrix. The base station and UE may determine a redistribution matrix that provides a reduced variance of transmission powers for a number of transmission channels, where a product of the null space matrix and the redistribution matrix may be computed and added to the precoding matrix to generate a modified precoding matrix. The modified precoding matrix may be used to generate the communications from the base station and UE with reduced power variance across channels.

Abstract: Systems, methods, computer-readable medium, and apparatus are disclosed that allow for control information to be provided in an efficient manner during short burst transmission. For example, an apparatus may be configured to receive downlink control information (DCI) that indicates an allocated resource from a base station. The apparatus may also receive data from the base station. The apparatus may generate a cyclically shifted sequence that corresponds to a sequence that is cyclically shifted based on at least one of an ACK or NACK for the received data and a SR. The apparatus may then transmit the cyclically shifted sequence in the allocated resource within one symbol period of a slot of a subframe to the base station. Thus, by transmitting the SR and the ACK/NACK in one symbol, control information for short burst transmissions can be provided in a more temporally efficient manner without adding excessive complexity to the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates a first control resource set (CORESET) configured for a first category of UEs and a second CORESET configured for a second category of UEs with which the UE is associated, wherein the first CORESET has a first frequency domain resource allocation, and wherein the second CORESET overlaps in time with the first CORESET and has a second frequency domain resource allocation that is a subset of the first frequency domain resource allocation. The UE may monitor for a physical downlink control channel (PDCCH) candidate based at least in part on a determination that the PDCCH candidate is fully contained within the second frequency domain resource allocation. Numerous other aspects are provided.
