Abstract

Example embodiments of the present disclosure relate to apparatuses, methods, and computer-readable storage media for cell activation. In a method, a first device receives an activation command from a second device for activating a plurality of cells. The first device then transmits a first measurement result for a first set of cells among the plurality of cells to the second device. The activation delay for activating the plurality of cells is based on a number of cells in a different second group of cells among the plurality of cells. The second set of cells satisfies at least one condition that the cells in the second set of cells are discontinuous with the cells in the first set of cells or that the timing for the cells in the second set of cells is different from the timing for the cells in the first set of cells.

Description

Cell activation Technical Field Various example embodiments of the present disclosure relate generally to the field of telecommunications and, in particular, relate to an apparatus, method, and computer-readable storage medium for cell activation. Background In a New Radio (NR) -as in Long Term Evolution (LTE), a secondary cell (SCell) may be activated or deactivated (deactivated). The transition between the active state and the inactive state may be based on a Medium Access Control (MAC) Control Element (CE) command from the network, such as an SCell activation command or an SCell deactivation command. When a User Equipment (UE) activates a deactivated SCell, time (i.e., an activation delay) is required to transition from a deactivated state to an activated state. In release 18 (R18), the UE may send a layer 3 (L3) measurement report after the SCell activation command to reduce activation delay. It has been agreed that L3 reporting may be applied to multiple SCell activation. However, if the UE sends an L3 report after the SCell activation command, how to activate multiple scells remains pending.
