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: Some aspects of this disclosure relate to apparatuses and methods for implementing one or more low-power wake-up receivers (LP-WUR) at the UE and for implementing mechanisms for improving receiver sensitivity loss for the LP-WUR. According to some aspects, apparatuses and methods are provided to improve the receiver sensitivity loss for the LP-WUR using time domain coverage improvement, power domain coverage improvement, spatial domain coverage improvement, and/or frequency domain coverage improvement.

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.

Abstract: This disclosure relates to techniques for selecting time domain resources in a wireless communication system. A wireless device and a cellular base station may establish a wireless link. The wireless device may receive an uplink grant that provides multiple uplink transmission occasions. The wireless device may select a subset of the multiple uplink transmission occasions and may perform uplink transmissions during the selected subset. The subset selected by the wireless device may be determined based on a resource adjustment rule for the wireless device. Each of the uplink transmissions may include an indication of uplink transmission occasions that are unused by the wireless device.

Abstract: A user equipment (UE) includes a transceiver and a processor configured to receive, from a network via the transceiver, a configuration of channel state information (CSI) report characteristics. The CSI report characteristics include one or more of: a maximum size of a CSI report payload, a maximum number of bits per layer or rank, a neural network (NN) identification (ID), or an expected CSI report content type. The processor is configured to generate a CSI report, in accordance with the received CSI report characteristics, to transmit to the network via the transceiver.

Abstract: A user equipment (UE), a baseband processor or other network device can operate in a new radio (NR) unlicensed network to correlate resource selection with shared spectrum channel access. The device can perform a resource selection procedures within a resource selection window (RSW) to determine a set of candidate resources, and a clear channel assessment (CCA). A resource selection of one or more resources can be performed from the set of candidate resources to enable a sidelink (SL) communication. The CCA initiates after an aperiodic traffic arrival, after a previous transmission, or after the resource selection is completed.
