Abstract: A method for performing sidelink transmission over an unlicensed band is provided. The method includes performing a first-type listen-before-talk (LBT) process on the unlicensed band to obtain a channel occupancy time (COT) for the sidelink transmission. The first-type LBT process includes a random backoff process. Duration of the random backoff process is determined by a randomly generated LBT counter. The method further includes determining, based on a result from a sensing operation performed on the unlicensed band within a sensing window, a plurality of candidate sidelink resources on the unlicensed band within a sidelink resource selection window. The method also includes selecting, based on a completion time point of the first-type LBT process, a sidelink resource from the plurality of candidate sidelink resources. The method also includes performing the sidelink transmission within the obtained COT on the selected sidelink resource.

Abstract: A method of wireless communication of a UE is provided. The UE determines K1 information bits carrying one or more CSI reports, the one or more reports including a first CSI report, K1 being an integer greater than 0. The UE selects K2 information bits from the K1 information bits, the K2 information bits excluding a part of information bits of the first CSI report, K2 being an integer greater than 0 and smaller than K1. The UE determines that the K2 information bits are in a first predetermined relationship with a threshold. The UE transmits E2 encoded bits derived from the K2 information bits in a physical up-link channel to a base station, E2 being an integer greater than 0.

Abstract: A method of power control can include receiving at a UE a first downlink reference signal from a repeater and a second downlink reference signal from a base station, the first downlink reference signal corresponding to a first path that is between the UE and the base station and passes the repeater, the second downlink reference signal corresponding to a second path that is between the UE and the base station. The UE estimates a first uplink path loss of the first path and a second uplink path loss of the second path and determine a first uplink transmit power corresponding to the first path and a second uplink transmit power corresponding to the second path. The UE performs an uplink transmission on the first path based on the first uplink transmit power and on the second path based on the second uplink transmit power.

Abstract: A synergetic communication method for relay node identification (ID) acquisition is proposed. The network node may generate a configuration based on the relay node information from a user equipment (UE) to configure the relay node ID for the relay node in an aggregated group. The network node may schedule the operations of the devices of the aggregated group based on the configuration. The UE may detect the relay node and assign the relay node ID configured by the network node to the relay node in the aggregated group. Therefore, when the relay node in the aggregated group cannot directly obtain the relay node ID from the network node, the UE can assist of obtaining the relay node ID from the network node and assigning the relay node ID to the relay node in the aggregated group.

Abstract: A method for allocating sidelink resource is provided. The method is applied to a first UE in a sidelink communication to transmit signal to a second UE which is a peer receiving (peer-Rx) UE of the first UE. The method includes the steps of maintaining, a counter to record how many remaining periodic reservations of sidelink resource to be used for sidelink signal transmission, wherein the periodic reservations are associated with a reservation period; receiving, in the sidelink communication, assistance information from the second UE or from a third UE which is not the peer-Rx UE of the first UE; and determining, whether to reselect a new sidelink resource different from the sidelink resource comprising the remaining periodic reservations according to the receiving assistance information even if the counter is greater than 0, to transmit signal to the second UE.

Abstract: A method can include determining candidate sidelink resources by a user equipment (UE) for sidelink transmission on an unlicensed band from a sidelink resource selection window based on results of a sensing operation on the unlicensed band during a sidelink sensing window, selecting a sidelink resource from the candidate sidelink resources, performing a listen-before-talk (LBT) process on the unlicensed band to obtain a channel occupancy time (COT), and performing a sidelink transmission within the COT using the first sidelink resource. The selection of the sidelink resource can be based on an LBT time that is a predicted duration of a random backoff process of the first LBT process. Also, the first sidelink resource can be selected from the candidate sidelink resources without randomization.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives, from a base station, a trigger for reporting M CSI reports, M being an integer greater than 0. The UE determines that P processing units are available for calculation of CSI reports, each of the P processing units indicating a predetermined amount of computing power of the UE. The UE selects N CSI reports from the M CSI reports in accordance with a predetermined rule, N being a maximum integer that allows total processing units assigned for calculation of the N CSI reports to be smaller than or equal to the P processing units. The UE updates the N CSI reports.
