摘要： Techniques for performing rank-dependent precoding for a MIMO transmission are described. Each rank may be associated with a set of at least one precoding vector or matrix that can provide good performance for that rank. A transmitter may obtain a precoding vector for a rank-1 transmission from a first set containing at least one column vector of a unitary matrix, e.g., a Fourier matrix. The transmitter may perform precoding for the rank-1 transmission based on the precoding vector. The transmitter may obtain a precoding matrix for a rank-2 transmission from a second set containing an identity matrix. The transmitter may perform precoding for the rank-2 transmission based on the precoding matrix. For the rank-2 transmission, the transmitter may select the identity matrix as the precoding matrix if a MIMO channel resembles a diagonal channel (which may be determined based on antenna configurations) and may select the unitary matrix otherwise.

摘要： Techniques for efficiently deriving uplink channel estimates without consuming much additional uplink resources are described. A user equipment (UE) may send a request for uplink resources on a request channel (REQCH) whenever the UE desires to transmit data on the uplink. The UE may send the REQCH on a set of subcarriers and from multiple antennas, e.g., send REQCH data on data subcarriers and pilot on pilot subcarriers. A Node B may receive the request, estimate the complex channel gains for the pilot subcarriers based on received pilot symbols, and coherently demodulate received data symbols based on the channel gain estimates. The Node B may estimate the complex channel gains for the data subcarriers based on demodulated data symbols and derive a channel estimate for each UE antenna based on the channel gain estimates for the pilot and data subcarriers. The Node B may use the channel estimates for MIMO scheduling, subband scheduling, and rate selection.

摘要： Aspects relate to sharing a channel occupancy time (COT) initiated by a network access node (e.g., a base station) with one or more wireless communication devices for sidelink communication between the wireless communication devices. In this example, the network access node can transmit a COT structure indication (COT-SI) to the wireless communication device (s) indicating the COT resources (e.g., time and frequency resources) of the COT that may be shared with sidelink. In some examples, the wireless communication device can receive a message from the network access node including a COT sharing indicator indicating whether COT sidelink sharing is enabled or disabled.

摘要： Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may transmit a sidelink message in accordance with one or more parameters associated with a priority of the sidelink message. The UE may determine a channel access priority class (CAPC) associated with the sidelink message based on the priority of the sidelink message. The UE may perform a listen-before-talk (LBT) procedure in accordance with the CAPC to gain access to a wireless channel for a channel occupancy time (COT). The UE may select a set of starting positions relative to the COT based on the priority, the CAPC, or both. The UE may transmit the sidelink message within the COT based on a starting position of the set of starting positions and the LBT procedure. The UE may perform a quantity of one or more retransmissions of the sidelink message based on the CAPC.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE, a first channel occupancy time (COT) sharing request. The UE may transmit, to a third UE, after a time window has elapsed, a second COT sharing request, wherein the second COT sharing request is transmitted based at least in part on the first UE having received no response to the first COT sharing request within the time window or the first UE having received a negative response to the first COT sharing request within the time window. Numerous other aspects are described.
