Abstract: Uplink precoding in closed loop transmit diversity (CLTD). The methods and apparatus relate to precoder operations during an initial stage using default precoder tap weights, and a second stage wherein precoder weights obtained from a precoder control indicator channel information are used, provided the signal quality of the precoder control indicator channel is sufficiently reliable. The methods and apparatus also relate to procedures for responding to detection of an unreliable pre-coding control information (PCI) carried in a downlink feedback signal.

Abstract: A method, apparatus, and system for multiple wireless transmit/receive units (WTRUs) communicating with a base station are disclosed. A base station, such as an eNB, may assign each WTRU of a plurality of WTRUs a portion of a transmission time interval (TTI) and then send that assignment to each respective WTRU in a control channel. The base station may then send data to one or more WTRUs in their respective assigned portions on a physical downlink shared channel (PDSCH). The portion may be one or a plurality of a time slots. The portion may be a fraction of the TTI.

Abstract: A method and an apparatus for serving high speed downlink shared channel (HS-DSCH) cell change are disclosed. A wireless transmit/receive unit (WTRU) receives pre-configured serving cell information for a target cell. The WTRU reports a measurement report and starts monitoring a high speed shared control channel (HS-SCCH) on the target cell. The WTRU may receive an HS-SCCH order over the target cell and/or a radio resource control (RRC) reconfiguration message over a source cell indicating a serving HS-DSCH cell change to the target cell. The WTRU may act upon all information elements of the RRC reconfiguration message in case that the RRC reconfiguration message is received prior to the HS-SCCH order, and act upon the pre-configured serving cell information in case that the HS-SCCH order is received prior to the RRC reconfiguration message.

Abstract: A method performed by an anchor wireless transmit/receive unit (WTRU) having an Extended Reality (XR) application includes transmitting to a base station (BS) a request for a candidate set of collaborative WTRUs, the request including pose information to identify the candidate set of collaborative WTRUs, receiving from the BS a first set of collaborative WTRUs, determining, by the anchor WTRU, a second set of WTRUs from the first set of WTRUs that align with at least one of a Field of View (FoV) requirement, the pose information, and XR application parameters of the anchor WTRU, and transmitting, to the BS, an indication of the second set of WTRUs as selected collaborative WTRUs.

Abstract: Apparatuses and methods of flow-based processing is wireless systems are described. For example, in one method, a WTRU may determine that one or more data units correspond to a flow of such data units. The WTRU may perform such determination as a function of one or more matching rule(s). Flow-based processing may be enabled in the layer 2/layer 1 chain by per-packet determination using one or more rules, for example by routing through the applicable processing functions and/or using the applicable configuration and/or mapping to the applicable uplink physical layer functions and/or resources. One or more functions such as scheduling request, buffer status reporting, HARQ processing, and/or radio link failure and recovery may be controlled based on the policy associated with the flow corresponding to the data being processed.
