1. A method for monitoring a licensed-assisted access (LAA) cell, the method comprising:
- receiving, by user equipment, notification signaling sent from a base station, wherein the notification signaling is used to instruct the user equipment to monitor the target licensed-assisted access (LAA) cell;
obtaining, by the user equipment, an index of a preamble sequence of the target LAA cell;
after a first preset time period elapses from a time at which the notification signaling is received, monitoring, by the user equipment, the preamble sequence of the target LAA cell within a second preset time period in accordance with the index; and
when the preamble sequence of the target LAA cell is obtained within the second preset time period, determining, by the user equipment, that the base station succeeds in contention for the target LAA cell and that the target LAA cell is available.

Abstract
The present disclosure provides a method and device for monitoring a licensed-assisted access cell. The method includes user equipment receiving notification signaling from a base station, where the notification signaling is used to instruct the user equipment to monitor a target LAA cell. The user equipment monitors for a specified signal of the target LAA cell after receiving the notification signaling. In this way, user equipment does not need to continually monitor or receive a signal of an LAA cell and power consumption can be reduced.

8. A user equipment, comprising:
-
a processor; and a non-transitory computer readable storage medium storing instructions that, when executed by the processor, cause the user equipment to; receive notification signaling sent from a base station, wherein the notification signaling is used to instruct the user equipment to monitor a target licensed-assisted access (LAA) cell; obtain an index of a preamble sequence of the target LAA cell; after a first preset time period elapses from a time at which the notification signaling is received, monitor the preamble sequence of the target LAA cell within a second preset time period in accordance with the index; and when the preamble sequence of the target LAA cell is obtained within the second preset time period, determine that the base station succeeds in contention for the target LAA cell and that the target LAA cell is available. - View Dependent Claims (9, 10, 11, 12, 13, 14)
