Abstract: This application relates to wireless communications, including methods and apparatus to manage uplink (UL) transmit switching with multiple timing advance groups (TAGs) for wireless devices. A wireless device is configured to use multiple carriers selected from a set of available carriers that can be associated with different TAGs. When a second set of carriers, used after switching from a first set of carriers, includes carriers that belong to different TAGs, the wireless device determines whether to transmit on one or more first uplink transmission occasions for each of the carriers in the second set of carriers based on whether a first UL transmission occasion for at least one carrier overlaps a switching gap time period. The wireless device can disallow transmission on first UL transmission occasions of one or more carriers to accommodate the overlap.

Abstract: Techniques for a wireless device to share a Channel Occupancy Time (COT) in a sidelink (SL) channel are disclosed. The techniques include a method for sharing a Channel Occupancy Time (COT) in a sidelink (SL) channel that includes performing a Clear Channel Assessment (CCA) by a first wireless device to initialize the COT. The first wireless device determines that a portion of the COT may be shared, and transmits to one or more qualifying wireless devices, first Sidelink Control Information (SCI). The first SCI may include a destination identification (ID), an offset, and a SL duration. The destination ID indicates one or more qualifying wireless devices that may share the COT, and the SL duration defines a duration of time available for the one or more qualifying wireless devices to share the COT. The first wireless device may resume transmission in the COT.

Abstract: This disclosure relates to techniques for performing physical uplink control channel repetitions before dedicated physical uplink control channel resource configuration in a wireless communication system. A wireless device may receive configuration information indicating that physical uplink control channel repetition before dedicated physical uplink control channel resource configuration is supported. The wireless device may perform a physical uplink control channel transmission with repetition before dedicated physical uplink control channel resource configuration based at least in part on the configuration information.

Abstract: Apparatus and methods are provided for a user equipment (UE) to control sidelink power allocation on multiple carriers. The UE determines, from among a plurality of physical sidelink feedback channels (PSFCHs) scheduled for simultaneous transmission on the multiple carriers, prioritized PSFCHs to simultaneously transmit across the multiple carriers based at least in part on a capability of the UE for a maximum number of simultaneous PSFCH transmissions per carrier of the multiple carriers and a total transmission power PCMAX of the UE, where j is an index of a jth-carrier of the multiple carriers. The UE determines allocated transmission power for the prioritized PSFCHs. Then, the UE simultaneously transmits the prioritized PSFCHs on the multiple carriers according to the allocated transmission power.

Abstract: Systems, methods, and circuitries are provided for aligning a number of eigen-vectors summarizing channel state information to a number of input nodes of an AI-based CSI feedback compression encoder. In one example, a method includes receiving a channel state information (CSI) report configuration that indicates a number of PRBs; determining a number of subbands and a respective number of PRBs in each respective subband; and generating a plurality of eigen-vectors, wherein one or more of the eigen-vectors summarizes a channel state matrix across a respective subband. A number eigen-vectors in the plurality corresponds to number of inputs of an artificial intelligence (AI) encoder used for CSI feedback compression.
