Abstract: Methods, systems, and devices for wireless communications are described. In some aspects, a user equipment (UE) and a network entity may support one or more signaling-based mechanisms according to which the network entity may inform the UE of which time and frequency resources may be used for full-duplex communication. The network entity transmit a first message to configure multiple resource block (RB) sets for the UE, where each RB set is associated with unique identifying information. To inform the UE of which time and frequency resources may be used for full-duplex communication, the network entity may transmit a second message that indicates one or more slot formats on a per RB set basis. As such, the network entity may schedule the UE for full-duplex communication in accordance with indicating that overlapping symbols of a first RB set and a second RB set are allocated for uplink and downlink, respectively.

Abstract: Methods, systems, and devices for wireless communications are described for beam selection based on user pose information provided by an extended reality (XR) application. The pose information may be used to determine a position of the UE, and one or more beam parameters may be requested based on the position of the UE. The position information of the UE may include position information for a current time period, predictive position information for one or more future time periods, or any combinations thereof. The UE may transmit a beam request to a base station for one or more beams for the current time period, for one or more future time periods, or any combinations thereof. The UE may request a switch between beams of differing beamwidths or having the same beamwidth, or request a change of a beamwidth of an existing beam.

Abstract: Aspects presented herein may enhance the configuration of the scheduling offset for communication devices within a channelized frequency band. In one aspect, a UE receives a PDCCH including a scheduling offset parameter. The PDCCH schedules one of a PDSCH for reception in a first sub-band within a BWP or provides an uplink scheduling grant of a PUSCH for transmission in a second sub-band within the BWP. The UE communicates with a base station based on one of a slot for receiving the PDSCH based on the first sub-band within the BWP and the scheduling offset parameter when the PDCCH schedules the PDSCH, or a slot for transmitting the PUSCH based on the second sub-band within the BWP and the scheduling offset parameter when a PUCCH is used to schedule the PUSCH.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first sensing signal of a radio frequency (RF) sensing procedure at a first transmit power. The UE may receive, from a base station at least in part in response to the first sensing signal, a power control message for sensing signals of the RF sensing procedure. The power control message may indicate a power control strategy for transmitting sensing signals of the RF sensing procedure. The UE may then transmit, at a second transmit power based on the received power control message, a second sensing signal of the RF sensing procedure.

Abstract: Certain aspects of the present disclosure provide techniques for channel access in an unlicensed spectrum. An example method of wireless communication by a user equipment includes receiving a resource grant indicating a plurality of resource candidates for an uplink signal. The method also includes sensing for energy, in response to the resource grant, over one or more of the resource candidates in a first sensing occasion before a transmission occasion of the uplink signal. The method further includes transmitting, during the transmission occasion, the uplink signal using a subset of the resource candidates selected based at least in part on energy sensed in the first sensing occasion.

Abstract: Methods, systems, and devices for wireless communications are described in which RF-domain wireless routers may repeat, extend, or redirect beamformed wireless signals received from one or more transmitters to one or more receivers. The router may receive transmissions at a mmW frequency using a first array of antenna elements, and provide the transmissions to a beamforming network, such as a Butler matrix, that outputs one or more a signals to a switching network. The switching network may perform switching to provide the one or more signals to desired inputs of an output beamforming network that outputs beamformed transmission beams via a second array of antenna elements.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at an integrated access and backhaul (TAB) node. The TAB node receives a first delay parameter and a second delay parameter associated with a packet, the first delay parameter being associated with a discard determination for the packet and the second delay parameter being associated with scheduling the packet for transmission. The TAB node performs a discard decision for the packet based on the first delay parameter associated or schedules the packet for transmission to a second TAB node or a user equipment (UE) using a second delay parameter associated with the packet. A central unit (CU) of an TAB network may indicate, to an TAB node, the second delay parameter for scheduling a packet and the first delay parameter for determining whether to discard the packet.
