Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit, from a UE to a base station, one or more reference signals over a channel. The UE may receive, from the base station based at least in part on transmitting the one or more reference signals, control signaling indicating a precoding matrix indicator (PMI) and a rank indicator (RI) based at least in part on the UE having at least eight transmit antennas and based at least in part on a phase difference between different subsets of transmit antennas of the at least eight transmit antennas. The UE may transmit, to the base station, an uplink transmission configured according to the PMI and the RI.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may communicate on first and second carriers, and may support either two transmit chains or three transmit chains on a second carrier. A base station may configure different sounding reference signal (SRS) resources for different numbers of transmit chains. SRS resources configured with two ports may indicate two transmit chains, and SRS resource configured with three ports may indicate three transmit chains. The base station may indicate an index associated with an SRS resource, and the UE may select (e.g., based on a mapping between the SRS Configuration Information resource index and a number of SRS ports and a number of transmit chains), a corresponding SRS resource, number of ports, number of transmit chains, or any combination thereof. The base station may indicate a number of transmit chains for a given SRS resource based on a PMI index.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may select a codebook for a multiple-input multiple-output (MIMO) communication from among one or more codebooks that include one or more of non-coherent codebooks for 6 or 8 antennas of the wireless communication device, partially-coherent codebooks for multiple paired antennas of the 6 or 8 antennas of the wireless communication device, or full-coherent codebooks for the 6 or 8 antennas of the wireless communication device. The wireless communication device may transmit or receiving the communication using the codebook. Numerous other aspects are described.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, a network device can receive one or more radio frequency (RF) sensing resources. The network device can determine RF sensing measurements based on the one or more RF sensing resources. For instance, the RF sensing measurements may be based on at least one use case for RF sensing. The network device can transmit, to a network entity, a measurement report comprising the RF sensing measurements for the at least one use case for the RF sensing.

Abstract: Disclosed are techniques for wireless sensing. In an aspect, a network node detects a collision between at least one wireless communication signal scheduled to be transmitted by the network node and two or more bundled radar reference signals scheduled to be transmitted by the network node, wherein the at least one wireless communication signal is scheduled to be transmitted during a gap between a first radar reference signal and a second radar reference signal of the two or more bundled radar reference signals; performs a collision avoidance operation based on detection of the collision, and transmits the two or more bundled radar reference signals.

Abstract: Certain aspects of the present disclosure provide techniques for adaptive grouping for cooperative radar sensing. A method for wireless communications by a first network entity includes receiving, from a second network entity, first grouping information comprising an indication of a first plurality of network entities, the first grouping information associated with a first time-period; receiving, from the second network entity, second grouping information comprising an indication of a second plurality of network entities, the second grouping information associated with a second time-period; receiving a first radar signal during the first time-period; receiving a second radar signal during the second time-period; transmitting, to the second network entity, first sensing information based on the first radar signal; and transmitting, to the second network entity, second sensing information based on the second radar signal.

Abstract: A method of wireless communication by a user equipment (UE) includes receiving different sets of parameters from different sources as input to a receiver neural network. The method also includes receiving, from a base station, a set of target long-term energy values associated with the receiver neural network. The method further includes calculating a scaling factor for each of the different sets of parameters based on the set of target long-term energy values, and separately scaling each of the different sets of parameters based on the scaling factor calculated for that set in order to generate multiple sets of scaled parameters. The method still further includes transmitting the multiple sets of scaled parameters to the receiver neural network.
