摘要： A user equipment (UE) may be configured/scheduled with uplink (UL) transmissions over multiple channels. Each UL transmission is aligned with a boundary of a UE fixed period frame (FFP). For each UL transmission, the UE may determine whether a gNB has initiated a channel occupancy time (COT) in a gNB FFP over a corresponding channel. If the COT is not initiated, the UE may initiate a COT in the UE FFP over the channel when the channel is available, by transmitting a corresponding UL transmission over the channel in the UE FFP. The UE may send, to the gNB, information indicating UE-initiated COT channel(s) of the multiple channels over which COT(s) have been initiated by the UE. The gNB may provide feedback for the UL transmissions based on the information.

摘要： According to various embodiments, a wireless communication device divides a plurality of transmission beams into one or more groups of transmission beams including at least a first group of transmission beams. The wireless communication device determines a first sensing beam requirement for the first group of transmission beams. The wireless communication device determines a first sensing beam and a first scale factor so that the first sensing beam satisfies the first sensing beam requirement scaled by the first scale factor. The first sensing beam is selected from a set of candidate sensing beams. The wireless communication device performs a first Clear Channel Assessment (CCA) using the first sensing beam and a first energy detection threshold (EDT), the first EDT determined in accordance with the first scale factor.

摘要： A user equipment (UE) may receive first configuration information of a carrier of a serving cell, including a first association of a first group of uplink (UL) signals or channels on the carrier in the serving cell with a first UL timing advance group (TAG) of the UE, and second configuration information of the carrier including a second association of a second group of UL signals or channels on the carrier with a second UL TAG of the UE. The UE may transmit a UL signal/channel in the first group of UL signals or channels according to a TA value of the first UL TAG, and transmit a UL signal/channel in the second group of UL signals or channels according to a TA value of the second UL TAG.

摘要： An embodiment method, by a user equipment (UE), includes performing a channel measurement (CM) on a first subset of a set of non-zero-power (NZP) CSI reference signal (CSI-RS) resources and an interference measurement (IM) on at least a second subset of the set of NZP CSI-RS resources. The second subset includes one or more NZP CSI-RS ports. The IM is performed according to assumptions: each NZP CSI-RS port in the second subset corresponds to an interference transmission layer, the IM being in accordance with a set of energy per resource element ratios each associated with one NZP CSI-RS resource in the second subset; and other interference not associated with the interference transmission layers is on the first and second subsets. The method includes generating a channel state information (CSI) report based on the CM and IM and transmitting the CSI report to a network.
