Abstract: According to embodiments, a UE receives a first signaling including a first configuration of a first CSI-RS for tracking for an SCell. The first configuration is associated with a first ID. The UE receives a second signaling including a second configuration of an RS for fast SCell activation of the SCell. The second configuration is associated with a second ID. The second configuration includes the first ID. The UE receives a MAC CE message including an SCell activation command indicating to activate the SCell and the second ID. The UE receives the RS for the fast SCell activation of the SCell. The RS includes a first burst of the first CSI-RS for tracking. The UE performs SCell activation for activating the SCell based at least on the RS upon receiving the SCell activation command. The UE sends a report indicating that the SCell is activated for the UE.

Abstract: A method performed by a first device includes communicating, by the first device, with a second device, a line of sight (LOS) determination request including a LOS indicator indicating that a LOS procedure is used in LOS characterization of a transmission between the first device and the second device; transmitting, by the second device, a first set of reference signals, via a first plurality of transmitting resources; and measuring, by the first device, a second set of reference signals, transmitted by the second device, via a second plurality of receiving resources. This method comprises of both embodiments when there is LOS characterization transmission between the first device and the second device, and when there is no LOS characterization transmission between the first device and the second device.

Abstract: An access node such as a gNB, when determining that a communication channel in a shared spectrum is clear, may send downlink control information (DCI) triggering a user equipment (UE) to measure a resource to determine whether the communication channel is available for the UE. The UE, triggered by the DCI, may measure received energy on resource, generate a measurement report and send the measurement report to the access node. The access node may determine whether to transmit data to the UE in the communication channel based on the measurement report.

Abstract: A user equipment (UE) in a frame based equipment (FBE) mode may determine that a communication channel in an unlicensed spectrum is available for use, and transmit, in the communication channel, a transmission to a gNB in a fixed frame period (FFP) associated with the UE to initiate a channel occupancy time (COT) by the UE in the FFP. The transmission starts at the beginning of the FFP and ends before an idle period within the FFP. The gNB receives the transmission and, based thereon, determines that the UE has initiated the COT. The gNB may acknowledge or reject initiation of the COT by the UE.

Abstract: A user equipment (UE) may measure reference signals (RSs) that are transmitted on one or more RS resources, whereby generating a RS measurement. The UE may determine, based on the RS measurement and a reporting rule, a RS resource of the one or more RS resources as a first type of resource of a plurality types of resources, and based thereon, generates a channel state information (CSI) report indicating the RS resource determined as the first type of resource, and reports the CSI report.

Abstract: According to embodiments, a UE receives, from a network device, a configuration of a sounding reference signals (SRS) resource with 8 antenna ports, a transmission comb configuration for the SRS resource, and a cyclic shift (CS) configuration for the SRS resource. The transmission comb configuration indicates a comb value K. K is one of 2, 4, or 8. The transmission comb configuration further indicates a configured comb offset (k). k is an integer between 0 and K−1. The CS configuration indicates CS positions. The UE maps each port of the 8 antenna ports to corresponding resource elements (REs) in the frequency domain and a corresponding CS. The corresponding REs are a subset of a plurality of REs and on every K-th RE with an offset based on the configured comb offset (k) within an SRS transmission bandwidth. The UE transmits SRSs using the 8 antenna ports based on the mapping.
