    摘要： A user equipment (UE) is served by a serving cell of a network and is configured to measure channel state information reference signals (CSI-RS) from a target cell. The UE receives, from the serving cell, a measurement configuration message indicating the UE is to measure CSI-RS from a target cell of the network, wherein the measurement configuration message does not include Synchronization Signal Block (SSB) information for the target cell but further comprises an indication of whether the target cell transmits SSBs. The UE determines, based on at least the measurement configuration message, a time and frequency resource on which the CSI-RS of the target cell are to be transmitted and measures the CSI-RS of the target cell.

    摘要： Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a serving cell and a processor communicatively coupled to the transceiver. The processor is configured to determine a reference signal sequence that comprises a primary synchronization signal (PSS) sequence and a secondary synchronization signal (SSS) sequence of a target cell. The processor is further configured to receive a signal sequence from the target cell and calculate an overall correlation value based on the reference signal sequence and the received signal sequence. The processor is further configured to determine that the overall correlation value is above a threshold and detect a synchronization signal block (SSB) of the target cell based on the received signal sequence. Finally, the processor is configured to establish a wireless connection with the target cell based on the SSB.

    摘要： A user equipment (UE) may perform configured to perform layer 1 (L1) measurements and layer 3 (L3) measurements. The UE receives a first configuration for layer 1 (L1) measurements of a resource set comprising a plurality of reference signals (RS) and a second configuration for layer 3 (L3) measurements, the first configuration including periodic measurement occasions and a reporting periodicity for transmitting measurement reports comprising the L1 measurements, determines the L3 measurements collide with at least one of the plurality of RSs for the L1 measurements, wherein the colliding causes a determination of the L1 measurements to be muted for the at least one RS during at least one of the measurement occasions and alters at least a first measurement report so that the L1 measurements that collide with the L3 measurements are not reported in at least one reporting periodicity.

    摘要： A base station of a network operates as a serving cell for a user equipment (UE) and configures the UE to measure channel state information reference signals (CSI-RS) from the target cell. The base station determines whether a target cell of the network transmits Synchronization Signal Block (SSB) information and transmits, to the UE, a measurement configuration message indicating the UE is to measure channel state information reference signals (CSI-RS) from the target cell, wherein the measurement configuration message does not include SSB information for the target cell but further comprises an indication of whether the target cell transmits SSBs.
