Abstract: 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.

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 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: According to embodiments, a UE receives, from a source cell, a mobility pre-configuration radio resource control (RRC) message for random-access channel (RACH)-less access. The mobility pre-configuration RRC message indicates target timing advance (TA) assistance information. The UE receives, from the source cell, a lower layer target access command. The lower layer target access command indicates a most updated or latest network-updated time sensitive dynamic TA assistance information. The UE determines a target cell TA of a target cell based on a latest source cell TA of the source cell, a latest measured timing difference between reference signals (RSs) from the source cell and from the target cell, the most updated or latest network-updated time sensitive dynamic TA assistance information, and the target TA assistance information. The UE performs the RACH-less mobility access to the target cell based on the target cell TA.
