Abstract: Certain aspects are directed to a user equipment (UE) configured to receive reference signals from a network node via multiple resource element groups (REGs) including at least one REG carrying a downlink transmission. In some examples, the UE may be configured to receive, from the network node, communication parameters for a downlink transmission, the communication parameters indicative of a first resource element group (REG) bundle and a second REG bundle. In some examples, the UE may receive the downlink transmission via the first REG bundle. In some examples, the UE may be configured to perform channel estimation of the downlink transmission based on reference signals transmitted via the first REG bundle and the second REG bundle.

Abstract: Certain aspects of the present disclosure provide techniques for quasi-colocation (QCL) assumption for an aperiodic channel state information (A-CSI) reference signal (RS) configured with multiple transmission reception point (mTRP). A user equipment (UE) may receive signaling configuring the UE with a plurality of index values associated with different control resource sets (CORESETS). The UE may receive, from a base station (BS), first downlink control information (DCI) triggering an A-CSI-RS resource set for A-CSI reporting. The first DCI is received in a first CORESET of the different CORESETs associated with a first index value of the plurality of index values. The UE may determine a first time offset between the first DCI and the A-CSI-RS resource set. When the first time offset is smaller than a threshold time offset, the UE may determine a QCL assumption for receiving the A-CSI-RS based, at least in part, on the first index value.

Abstract: Techniques for signaling uplink transmission configuration indicator (TCI) states are disclosed. In an example, a base station may determine one or more capabilities of a user equipment (UE). The base station may also determine one or more uplink TCI states for the UE to use based on the one or more capabilities. The base station may also transmit, to the UE, signaling of the one or more uplink TCI states.

Abstract: In some implementations, a method of wireless communication includes receiving, at a user equipment (UE) from a base station, a downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH). The PDSCH includes a first transmission occasion and a second transmission occasion following the first transmission occasion during a single slot. The method further includes determining, at the UE, an overall processing time following a last symbol of the PDSCH.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for forming a virtual user equipment (UE) group and enhancing communication using joint reception and transmission mechanisms. For example, a UE may establish sidelink channels for communications with one or more other UEs. The UE and the one or more other UEs may form a virtual UE group (also interchangeably referred to as a virtual UE) using the sidelink channels. The UE may exchange information with other UEs in the virtual UE group to enhance communications between the one or more UEs of the virtual UE group and a network entity. The information exchanged depends on at least one of a joint reception mechanism or a joint transmission mechanism used by the virtual UE group. The UE communicates with the network entity based, at least in part, on the exchanged information.

Abstract: Inter-cell mobility across serving and non-serving cells based on layer 3 measurements is accomplished at the cost of increased delay. Inter-cell mobility across serving and non-serving cells based on layer 1 measurements minimized delay. A user equipment (UE) apparatus that is served by a serving cell of a base station receives, from the serving cell, a configuration to perform layer 1 (L1) measurements based on one or more reference signals from a non-serving cell. The UE also receives the one or more reference signals from the non-serving cell. The UE performs the L1 measurements on the one or more reference signals received from the non-serving cell based on the configuration received from the base station. The UE may perform the L1 measurements on a synchronization signal block (SSB), a channel state information reference signal (CSI-RS), or a positioning reference signal (PRS) from the non-serving cell.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a resource configuration for communications with a base station on a multiple sets of resources across multiple component carriers, the resource configuration including at least a first set of resources on a first component carrier and a second set of resources on a second component carrier. The UE may receive, from the base station, a downlink control information (DCI) message on the first component carrier, the DCI message including a DCI format that controls the multiple of sets of resources across the plurality of component carriers. The UE may determine that the first set of resources and the second set of resources are one of activated or released based on a first indication in the DCI message.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for maintaining, between a user equipment (UE) and a component of a base station (BS), a mutual understanding of multiple sets of linked physical downlink control channel (PDCCH) candidates if some PDCCH candidates of the multiple sets of linked PDCCH candidates occupy a same set of resources. In one aspect, the UE may select to monitor one of the PDCCH candidates that occupy the same set of resources in accordance with a prioritization rule. Upon selecting one of the PDCCH candidates that occupy the same set of resources for monitoring by the UE, the UE and the component of the BS may select a reference PDCCH candidate for one or more of the multiple sets of PDCCH candidates in accordance with a reference selection rule.
