In some example embodiments, there may be provided a method that includes receiving, at user equipment, an indication of a codepoint activation, wherein the codepoint activation indicates that a transmission configuration indicator state being activated is associated with a second physical cell identifier different from a first physical cell identifier of a serving cell of the user equipment, and in response to the transmission configuration indicator state being activated in association with the second physical cell identifier, suspending control channel monitoring of at least one set of core resources associated with the first physical cell identifier of the serving cell of the user equipment. Related systems, methods, and articles of manufacture are also disclosed.

Control channel monitoring rules for inter-cell beam management

There is provided a user equipment apparatus that includes at least one processor and at least one memory. The memory stores instructions which, when executed by the at least one processor, cause the user equipment apparatus at least to perform an initial cell search of one or more cells on a network. A synchronization raster includes a cluster of three raster points positioned every 600 kHz.
