Abstract: Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a first transmission/reception point (TRP) and a second TRP and a processor communicatively coupled to the transceiver. The UE is in a multi-TRP mode. The processor is configured to perform a first beam failure detection (BFD) procedure for the first TRP and a second BFD procedure for the second TRP. The processor is further configured to perform a first beam failure recovery (BFR) procedure for the first TRP responsive to a result of the first BFD procedure and a second BFR for the second TRP responsive to a result of the second BFD procedure. The processor is further configured to receive a configuration message, a BFD configuration, and a BFR configuration. The UE switches to a single-TRP mode upon receiving the configuration message. The processor is further configured to update the first BFD procedure based on the BFD configuration and update the first BFR procedure based on the BFR configuration. Finally, the processor is configured to perform the updated first BFD procedure and the updated first BFR procedure for the first TRP responsive to a result of the updated first BFD procedure.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for a user equipment (UE) having dual connectivity. The UE can communicate with a first primary base station in a first primary cell (PCell) and a second primary base station in a second PCell. The UE has dual connectivity in the second PCell using a first wireless carrier to communicate with the second primary base station and a second wireless carrier to communicate with a secondary base station in a primary secondary cell (PSCell). The UE receives a message from the first primary base station to perform a handover procedure. The UE performs the handover procedure according to the received message, and further perform an addition procedure for the secondary base station in parallel with the handover procedure. A start time of the addition procedure can be before an end time of the handover procedure.

Abstract: Some aspects include an apparatus, method, and computer program product for beamforming to perform received signal strength indicator (RSSI) measurements in a 5G wireless communications system. This beamforming may apply to RSSI measurements in an unlicensed spectrum. In some aspects, user equipment (UE) may use beam sweeping to analyze multiple received beams and to determine an RSSI measurement. When using beam sweeping, network nodes may use scheduling and/or measurement restrictions to avoid data collisions. These restrictions may apply to multiple active serving cells. In some aspects, a UE may use beam selection to determine an RSSI measurement. For example, the UE may select one or more beams from a serving component carrier (CC). In some aspects, a network node may indicate to the UE which beams to use for the RSSI measurement. In some aspects, the UE may use a frequency domain resource to perform the RSSI measurement.

Abstract: A user equipment (UE) is configured to receive synchronization signal blocks (SSBs) from a wireless network to estimate frequency and timing errors. The UE receives a quasi co-location (QCL) configuration between a synchronization signal block (SSB) and at least one of a further SSB or a tracking reference signal (TRS), receives the SSB and the at least one of the further SSB or the TRS and estimates a frequency and timing error for the SSB by combining, based on the QCL configuration, measurements for the SSB and measurements for the at least one of the further SSB or the TRS.

A cellular base station may generate control information in accordance with a set of criteria, wherein the set of criteria supports a special Secondary Cell (sSCell) which is a Secondary Cell (SCell) in scheduling a special Primary Cell (SpCell) which is either a Primary Cell (PCell) or a Primary Secondary Cell (PSCell). The cellular base station sends the control information to a wireless device. The control information may be associated with Type3-PDCCH CSS configuration including DCI Format 2_5 and 2_6, SCell dormancy behavior, scheduling restrictions, USS configuration including non-fallback and fallback DCI Formats, and interaction with Multi-DCI Multi-TRP operation. After receiving the control information, the wireless device may conduct corresponding performance.
