USER EQUIPMENT AND DISCONTINUOUS RECEPTION CONTROL METHOD IN MOBILE COMMUNICATION SYSTEM

摘要

User equipment that is capable of communicating by using M (M is greater than or equal to 2) component carriers (CCs) includes N (N is greater than or equal to 2) communication units for executing radio communication with a base station by using each of the M CCs, a controller for individually controlling an operation mode of each of the N communication units; and a timer for reporting to the controller that a constant time period is elapsed without receiving a further control signal, after receiving, by a communication unit of the N communication units, a control signal from the base station. When a report from the timer is received for a specific communication unit of the N communication units, the controller controls the operation mode of the specific communication unit, so that the operation mode the specific communication unit discontinuously transitions to an active mode.

1. User equipment capable of communicating by using M component carriers through carrier aggregation, the user equipment comprising:
N communication units configured to execute radio communication with a base station by using each of the M component carriers; a controller configured to individually control an operation mode of each of the N communication units; and a timer configured to report to the controller that a constant time period has elapsed without receiving a further control signal, after receiving, by a communication unit of the N communication units, a control signal from the base station, wherein M is greater than or equal to 2, wherein N is greater than or equal to 2, wherein, when a report from the timer is received for a specific communication unit of the N communication units, the controller is configured to control the operation mode of the specific communication unit such that the specific communication unit transitions to an active mode discontinuously, and wherein a specific plurality of communication units belonging to the N communication units is grouped such that operation modes of the specific plurality of communication units simultaneously transition to either active modes or inactive modes.
