Abstract: Methods, systems, and devices for wireless communications are described. A relay node may determine a channel status for each of a plurality of downlink beamforming directions between a parent node and the relay node based at least in part on a downlink beamforming direction between the relay node and a child node. The relay node may transmit a report to the parent node indicating at least a subset of the channel statuses and an indication that a respective downlink beamforming direction of the plurality of downlink beamforming directions corresponds to a respective channel status in the subset of the channel statuses. The relay node may receive a grant from the parent node indicating a first downlink beamforming direction. The relay node may monitor for a downlink transmission from the parent node based at least in part on the grant and the first downlink beamforming direction.

Abstract: Aspects of the present disclosure provide techniques for transmitting an uplink preemption indication in an integrated access and backhaul (IAB) system identifying the resources or symbols that may be punctured by the IAB in order to minimize self-interference at an IAB node when an ultra-reliable-low latency communications (URLLC) packet is received at the IAB node from one of a child IAB node or a user equipment (UE) during an on-going uplink transmission from an IAB node to a parent backhaul node.

Abstract: Methods, systems, and devices for wireless communications are described for enabling a network equipment to reduce interference for downlink (DL) transmissions to a first device by determining a transmit precoding matrix indicator (TPMI) for uplink (UL) transmissions transmitted by a second device based on feedback from the first device. The first device may determine a subset of possible TPMIs that the second device may use for UL transmissions for full-duplex communications. The first device may indicate the subset to the network equipment. Based on the subset indicated by the first device, the network equipment may determine a pairing of the first device and the second device for full-duplex communications. Additionally, the network equipment may determine a TPMI for the second device to use in UL transmissions and indicate the TPMI to the second device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information for an uplink control channel, wherein the configuration information includes at least one of: a first resource identifier associated with a non-full-duplex (non-FD) zone, or a second resource identifier associated with a full-duplex (FD) zone. The UE may transmit uplink control information (UCI) on the uplink control channel in at least one of the non-FD zone or the FD zone in accordance with the configuration information. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may obtain group control information in a group common physical downlink shared channel (PDSCH), determine resources for communicating on a shared channel based on the group control information, and communicate on the resources of the shared channel. A base station may configure a user equipment (UE) group comprising at least one UE, transmit, in a group common physical downlink shared channel (PDSCH), group control information for scheduling the at least one UE for communicating on a shared channel, and communicate on the shared channel with the at least one UE.

Abstract: Methods, systems, devices, and apparatuses for wireless communications that support transmission diversity enhancement for uplink control channel are described. Generally, the described techniques provide for enhanced performance of an uplink control channel such as a physical uplink control channel (PUCCH) through the use of transmission diversity. In some cases, multiple input multiple output (MIMO) techniques may be supported for transmission of an uplink control channel for a given format suitable for transmission diversity enhancement. A resource block (RB) used in an uplink control channel transmission may contain a number of resource elements (REs) across one or more resource blocks. According to some aspects, a transmit diversity scheme may be employed at the RE level through application of different spatial precoders for different groups of REs of a given RB.

Abstract: Certain aspects of the present disclosure provide techniques for channel state information (CSI) processing for fine granularity CSI. A method for wireless communications by a user equipment (UE) includes receiving a CSI reporting configuration. The CSI reporting configuration includes a number of frequency domain (FD) units and a FD unit size for CSI reporting. The UE determines a number of CSI processing units at the UE to use for processing the CSI report based on the number of FD units or the FD unit size for the CSI report. The UE processes the CSI report based on the determined number CSI processing units. In another method, the UE determines at least one threshold to use for determining whether to update a CSI report based on the number of FD units or the FD unit size for CSI reporting.

Abstract: A method, base station (BS), user equipment (UE), apparatus, and computer program product for wireless communication are provided. A BS and a UE may communicate using a narrowband Internet of Things (NB-IoT) communication system. However, a frequency, time, and/or power associated with transmission of a SIB1-NB on a non-anchor carrier may not be configured for NB-IoT. In some aspects, the BS may determine parameters, such as a time domain location parameter, a frequency domain location parameter, a quantity of repetitions, a power boosting parameter, and/or the like for a transmission in NB-IoT. In some aspects, a UE may determine to transmit a connection request message on a different carrier than a random access channel message.
