Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication. A user equipment (UE) may receive a downlink control information (DCI) indicating two or more transmission configuration indication (TCI) states for a physical downlink shared channel (PDSCH). The UE may differentiate that the two or more TCI states apply to all demodulation reference signal (DMRS) ports or all transmission layers across all resource blocks and symbols for the PDSCH from TCI states that apply to different sets of DMRS ports or different sets of resource blocks or symbols. The UE may generate a composite quasi-co-location (QCL) based on the two or more TCI states in response to the differentiating. The UE may receive the PDSCH based on the composite QCL.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for a UE to provide an indication when the quality of a group of previously-reported simultaneously receivable transmit beams has degraded to the point they are no longer simultaneously receivable.

Abstract: Aspects described herein relate to identifying a timing advance group (TAG) for a second remote radio header (RRH) that is different from a first RRH, the TAG associated with a timing advance (TA) offset, wherein the first RRH and the second RRH are associated with a serving cell, switching from the first RRH to the second RRH in accordance with the TAG and the associated TA offset, and transmitting, on an uplink communication channel, data to the second RRH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information associated with monitoring link quality on a non-serving cell of the UE, wherein the configuration information includes at least one of: information indicating a reference signal resource associated with the non-serving cell, or information indicating an uplink resource associated with the non-serving cell; monitor a reference signal of the non-serving cell based at least in part on the configuration information; and transmit, to a serving cell using the uplink resource, a channel quality indicator associated with the non-serving cell based at least in part on the monitoring. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to wireless communication networks having a capability of controlling the mapping of reference signals onto a carrier based on one or more Doppler parameters. A demodulation reference signal (DMRS) is mapped to a carrier according to a pattern based on one or more Doppler parameters, such as a Doppler frequency and/or a rate of change of channel conditions. In a further example, if an initial transmission of an information packet fails due to a high Doppler scenario, the probability of success of the retransmission may be improved by altering the DMRS configuration to account for the high Doppler scenario. Other aspects, examples, and features are also claimed and described.

Abstract: A configuration to enable a UE to switch an active BWP for one or more component carriers in a set of multiple component carriers. The apparatus receives a first configuration for carrier aggregation involving multiple component carriers. The apparatus receives an indication for a BWP switch for one component carrier of the multiple component carriers. The apparatus applies the BWP switch to the one component carrier and a set of additional component carriers.

Abstract: Aspects of the disclosure relate to Layer 1/Layer 2-centric inter-cell mobility. Within a serving cell having a plurality of remote radio heads, each remote radio head transmits a referenced signal that includes a PCI index unique to the remote radio head. A user equipment is configured with a beam management function that uses one of the reference signals as a source reference signal for the beam management. The source reference signal is uniquely tied to the corresponding remote radio head through its PCI index.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for enabling L1 (physical layer) and L2 (medium access control (MAC) layer) inter-cell mobility. More specifically, rules and operations performed during L1/L2 based cell handover operations. In certain aspects, a user equipment (UE) is configured to receive, from a network entity of a source cell via at least one of L1 or L2 signaling, a handover command for the UE to handover from the source cell to a target cell. The UE may determine at least one transient period during which the UE is served by both the source cell and the target cell, and perform the handover while communicating with the source cell and target cell during the transient period.

Abstract: Aspects of the present disclosure provide techniques for interference coordination between wireless nodes (e.g., nodes of an Integrated Access and Backhaul (TAB) network). The techniques generally include determining, by a first wireless node, resources for sending an indication of interference coordination to a second wireless node, and sending the indication to the second wireless node using the determined resources, as part of an interference coordination procedure.

Abstract: Certain aspects of the present disclosure provide techniques for selecting and indicating a quasi colocation (QCL) source signal for sidelink (SL) communications. For example, a scheduling node may select from multiple candidates a signal for a first user equipment (UE) to use as a spatial QCL source for a receive (RX) or transmit (TX) beam to use for communicating with a second UE on a SL interface. The scheduling node may then signal the first UE an indication of the selection of the signal.
