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 a first one or more physical sidelink shared channel communications associated with a first set of physical sidelink shared channel priorities and associated with a first feedback message codebook. The UE may receive a second one or more physical sidelink shared channel communications associated with a second set of physical sidelink shared channel priorities and associated with a second feedback message codebook. The UE may include transmit, based at least in part on a physical sidelink feedback channel feedback resource configuration, a first feedback message in a first physical sidelink feedback channel feedback resource and a second feedback message in a second physical sidelink feedback channel feedback resource.

Abstract: In an aspect, a user equipment (UE) may receive indications of positioning resources of a positioning resource pool, wherein the positioning resource pool includes a first positioning resource window having a first set of one or more contiguous positioning resources, a second positioning resource window having a second set of one or more contiguous positioning resources, and a third positioning resource window having a third set of one or more contiguous positioning resources extending between an end of the first positioning resource window and a start of the second positioning resource window. The UE may transmit a first positioning reference signal (PRS) on a first positioning resource reserved from the first positioning resource window. The UE may transmit a second PRS on a second positioning resource reserved from the second positioning resource window.

Abstract: Disclosed are systems and techniques for performing wireless communication. In some aspects, a method performed at a user equipment (UE) may include obtaining configuration information for communicating with one or more aircrafts. In some examples, the method can include generating a message based at least in part on the configuration information. In some cases, the method can include outputting the message for transmission to at least one aircraft of the one or more aircrafts.

Abstract: 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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a first network device using a first communication technology, an indication of a resource mapping between a first set of time resources for downlink communications using the first communication technology and a second set of time resources for downlink communications using a second communication technology. The UE may determine a timing for receiving a first message from a second network device using the second communication technology based on receiving the indication of the resource mapping. The UE may receive, from the second network device, the first message using the second communication technology based on determining the timing. The UE may transmit, to the first network device, a second message including feedback information using the first communication technology based on receiving the first message from the second network device using the second communication technology.

Abstract: Methods, systems, and devices for wireless communications are described for closed-loop precoding for multiple-input multiple-output for transmitter circle arrays, for example uniform circular array panels. In some aspects, a base station including a transmitter circle array may steer a beam to a user equipment (UE) using codebooks, quantization rules, and feedback from the user equipment. In some aspects, the same transmitter circle array may be used for both backhaul communications with a device at a fixed location, for example using beams formed via discrete Fourier transform (DFT) vectors, and access communications with a UE via non-DFT beams coded using closed-loop precoding.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a node may receive a first control channel associated with a multiple relay based communication. The node may identify a target node of a pay load of the first control channel based at least in part on at least one of: information included in the payload, or an identifier associated with the first control channel. The node may transmit a second control channel carrying the pay load toward the target node if the node is not the target node. The node may decode the payload, if the node is the target node. Numerous other aspects are described.
