Abstract: 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.

Abstract: A system is configured for reconfiguration of a Synchronization Signal Block (SSB) pattern. The system is configured for obtaining data including a configuration for a Synchronization Signal Block (SSB) transmission carrying a physical broadcast channel (PBCH), the configuration specifying, for an SSB of the configuration, resource elements (REs) allocated for transmitting a primary synchronization signal (PSS) to a user equipment (UE) and REs allocated for transmitting a secondary synchronization signal (SSS) to the UE. The system is configured for selecting a set of REs that are unused in the configuration for the SSB transmission, specifying a filling sequence for extending a synchronization signal or an SSB to the set of REs that are unused in the configuration of the SSB transmission, generating data including an enhanced configuration for the SSB transmission that includes the extended synchronization signal or the extended SSBs, and transmitting the SSB transmission using the enhanced configuration.

Abstract: 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.

Abstract: A user equipment (UE) may be configured to perform layer 1 (L1) measurement procedures and layer 3 (L3) measurement procedures. The UE configures a channel state information-reference signal (CSI-RS) layer 3 (L3) measurement window, identifies a collision between a layer 1 (L1) measurement operation and a L3 measurement operation and omits at least one L1 measurement in response to identifying the collision.

Abstract: 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.
