Abstract: Systems, methods, and devices for secondary cell activation using temporary reference signals and beam selection are provided. In one aspect, a method of wireless communication is performed by a UE and includes receiving, from a base station (BS) via a first cell, an activation command to activate a second cell different from the first cell. The method further includes receiving, from the BS via the second cell during a cell activation period, a first reference signal different from a synchronization signal block (SSB) based on beam information. The method further includes performing a first measurement of the first reference signal, and operating in the second cell based on the first measurement.

Abstract: A UE may enter a dormant state, e.g., for power savings. The systems, methods, and apparatus described herein may provide ways for the UE to transition between an active state and a dormant state, as well as UE behavior in a dormant state. The apparatus may be a UE configured to receive an indication of a bandwidth part (BWP) switch for a secondary cell and to transition between an active state and a dormant state for the secondary cell based on the indication of the BWP switch.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a carrier aggregation (CA) configuration for communications on a set of cells. The UE may determine that signals transmitted on the set of cells may be spatially quasi co-located based on the CA configuration and a predetermined relationship rule. The UE may determine that the signals are spatially co-located based on receiving multiple synchronization signal blocks (SSBs) that have a same SSB index, receiving a common SSB, assuming that an SSB and reference signals sourced by the SSB are spatially quasi co-located, receiving a signal from a particular cell of the set of cells, or receiving a common spatial QCL relationship during a configured period of time. Once the spatial QCL relationship is determined, the UE may receive the signals transmitted on the set of cells based on the spatial QCL relationship.

Abstract: Search space-BFR time occasions may overlap with other search space occasions. Additionally, if any CORESET other than a CORESET-BFR has lowest CORESET ID, the UE will prioritize receiving that CORESET and may miss the BFR response. Accordingly, assigning a priority to CORESETs or search spaces during BFR may be preferable. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may allocate a set of time-frequency resources to a plurality of CORESETs or a plurality of search spaces. The apparatus may assign a priority to each of the plurality of CORESETs or the plurality of search spaces. The apparatus may assign a highest priority to a CORESET for BFR or a search space for BFR.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determining that a first physical downlink control channel (PDCCH) candidate and a second PDCCH candidate in a control resource set (CORESET) are aligned with each other, wherein the first PDCCH candidate is a common search space (CSS) candidate and the second PDCCH candidate is a UE-specific search space (UESS) candidate; and decode downlink control information in accordance with a selected candidate, of the CSS candidate or the UESS candidate, based at least in part on a rule indicating whether the time-domain resource allocation is to be determined in accordance with the CSS candidate or the UESS candidate. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may obtain access to a base station by performing an initial access procedure within an initial access bandwidth. In some cases, the UE may monitor for a cell specific configuration in the initial access bandwidth that indicate one or more first common search spaces within the initial access bandwidth that the UE may monitor for control information. Additionally, the UE may receive dedicated signaling after the initial access procedure that indicates a downlink bandwidth part (BWP) and one or more second common search spaces within the downlink BWP to monitor for control information. Accordingly, the UE may monitor the first common search spaces, the second common search spaces, or both based on the dedicated signaling.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a phase tracking reference signal (PTRS) port is to be shared among a plurality of physical downlink shared channels (PDSCHs) transmitted by a plurality of transmit receive points (TRPs); receive PTRS pilot signals on one or more PDSCHs of the plurality of PDSCHs; and use the PTRS pilot signals for phase tracking estimation for the plurality of PDSCHs based at least in part on the determination that the PTRS port is to be shared among the plurality of PDSCHs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may determine to configure a user equipment (UE) to operate in a transmission/reception point (TRP) mode, wherein the TRP mode is a single-TRP mode or a multi-TRP mode. The BS may configure the UE to operate in the TRP mode based at least in part on a bandwidth part (BWP) switch or a trigger to switch between the multi-TRP mode and the single-TRP mode within a BWP. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive downlink control information within a control resource set (CORESET) configured with a wideband demodulation reference signal (DMRS) and including disjoint segments of resource blocks (RBs). The downlink control information may be located at least partially within a first segment of the disjoint segments and a second segment of the disjoint segments may be exclusive of the downlink control information. The downlink control information may include a grant of a set of resources for a downlink shared channel that overlaps with the CORESET. The UE may determine a rate matching operation for the wideband DMRS for a downlink shared channel for portions of the set of resources that overlap with the second segment of the disjoint segments, and receive the downlink shared channel on the set of resources according to the determined rate matching operation.
