Methods and apparatus for handling interruption of data transmission and / or reception on selected carriers in mobile communications

Abstract

Various solutions for measurement enhancements with respect to user equipment (UE) in mobile communications are described. An enhanced measurement gap (E-MG) occasion includes a radio frequency retuning time (RRT) period and a measurement length (ML) period. During the RRT period, the UE interrupts data transmission and / or reception on carriers within per-radio frequency (per-RF) or per-band group or per-UE including a primary cell and at least one secondary cell to perform radio frequency retuning. During the ML period, the UE selectively interrupts data transmission and / or reception on at least one selected carrier, while allowing other carriers to continue communication. Based on information reported by the UE, the network node schedules data transmission or reception on carriers not indicated to be interrupted during the ML period. By distinguishing full interruption during the RRT period from selective interruption during the ML period, unnecessary interruption is reduced and measurement efficiency is improved.
