Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, an indication of a monitoring window used by the base station to monitor for uplink transmissions from the UE. The UE may receive a control signal scheduling uplink resources for an uplink transmission by the UE on at least a first component carrier, the first component carrier in a first radio frequency spectrum band. The UE may reconfigure, in response to the received control signal, a first transmit chain of the UE from a second component carrier in a second radio frequency spectrum band to the first component carrier in the first radio frequency spectrum band for the uplink transmission. The UE may transmit, based at least in part on the indicated monitoring window and using at least the reconfigured first transmit chain, the uplink transmission on the first component carrier using the scheduled uplink resources.

Abstract: Methods, systems, and devices for wireless communications are described in which a base station operating in full-duplex mode may provide for reception of one or more higher priority transmissions using at least partially overlapping time-frequency resources as used for transmission of lower priority communications. In order to mitigate self-interference at the base station, a transmission power used for the overlapping time-frequency resources may be reduced. The base station may provide an indication of a subset of resources that have a reduced transmission power, an amount of the power reduction for the subset of resources, or both.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a sounding reference signal (SRS) that indicates that the UE is configured with a quantity of receive elements that is greater relative to a quantity of transmit elements with which the UE is configured. The UE may receive, based at least in part on transmitting the SRS, a first channel state information (CSI) reference signal (CSI-RS) set and a second CSI-RS set. The UE may transmit a CSI report that is based at least in part on the first CSI-RS set and the second CSI-RS set. Numerous other aspects are provided.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a sounding reference signal (SRS) configuration that indicates a maximum number of SRS ports and whether the UE is permitted to determine an actual number of SRS ports to be used for SRS transmission that is different from the maximum number of SRS ports. The UE may determine the actual number of SRS ports to be used for SRS transmission based at least in part on the SRS configuration. The UE may transmit one or more SRSs using the actual number of SRS ports. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for scheduling hybrid automatic repeat request (HARQ) feedback and controlling the transmit power of the HARQ feedback. An example method generally includes generating a configuration for physical uplink control channel (PUCCH) resource sets assigned to at least one user equipment (UE), wherein each of the PUCCH resources sets comprises PUCCH resources, transmitting the configuration for the PUCCH resource sets to the at least one UE, generating an uplink control reporting indication indicating the PUCCH resources associated with downlink demodulation reference signal (DMRS) port groups, transmitting the uplink control reporting indication, to the at least one UE, for use in reporting uplink control information (UCI), and receiving at least a part of the UCI associated with at least one of the downlink DMRS port groups from the at least one UE via the PUCCH resources indicated in the uplink control reporting indication.

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.
