Abstract: A method for power control for uplink transmission is provided. In an embodiment, a method in a user equipment (UE) for reference signal (RS) relationship specific uplink (UL) transmission power control includes transmitting, by the UE, a first UL signal according to a first power control set including at least one of a first target power, a second target power, a DL reference signal (RS) for pathloss estimation, a pathloss compensation factor, and a transmit power command (TPC). The first power control set is determined according to a first RS relationship between one first RS and a first UL signal.

Abstract: 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.

Abstract: According to embodiments, a network device configures for a first sounding reference signal (SRS) resource. The first SRS resource is associated with a first transmission parameter defined on a set of values. The network device configures for the first SRS resource, hopping of the first transmission parameter on a first subset of values of the set of values. The network device receives first SRSs on the first SRS resource. The first SRSs have the first transmission parameter hopping according to the first subset of values.

Abstract: A user equipment (UE) may receive, from a base station, a configuration indicating a first orthogonal cover code (OCC) length that is 4 and a second OCC length that is 2 for demodulation reference signals (DM-RSs) communications between the base station and the UE. The UE may receive a signaling indicating the UE to communicate DM-RS(s) according to the first OCC length or the second OCC length. The UE may communicate, with the base station, a DM-RS according to the first OCC length or the second OCC length indicated by the signaling.

Abstract: According to embodiments, a user equipment (UE) performs a first type of sensing in a sensing window to detect first one or more SL transmissions using a sidelink (SL) radio access technology (RAT). The UE performs a second type of sensing to detect second one or more transmissions using a non-SL RAT different from the SL RAT. The second type is different from the first type. The UE selects an SL resource in an unlicensed band in a selection window for an SL transmission based on the first type of sensing and the second type of sensing. The UE transmits the SL transmission via the SL resource using the SL RAT.
