Problems solved by technology

If a PDSCH-only DL CC is scheduled to be deactivated, but the PDSCH CC is not deactivated, it will cause unnecessary power consumption, especially when the PDSCH-only CC and other PDCCH CCs do not use a transceiver , the power consumption is more serious

Embodiment Construction

[0044] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0045] In a multi-carrier system, in order to increase the peak rate, the UE can work on multiple component carriers. The multi-carrier system will configure a set of working carriers for the UE according to the sum of the average rate of the service requested by the UE, and because the service of the UE may have Fluctuation and suddenness, when the UE traffic is relatively small, in order to better save power, the carrier in the working carrier set configured for the UE can be ...

Abstract

The invention discloses a method for determining an active state of a PDSCH (Physical Downlink Shared Channel) CC (Communication Centre), comprising the following steps: a network side device determines the active state of the PDSCH CC according to the active state of a PDCCH (Packet Dedicated Control Channel) CC, and indicates a user device to activate the CC according to the active state of the PDSCH CC when the active state of the PDSCH CC is in an activated state. In the embodiment of the invention, the active state of the PDSCH CC is determined according to the active state of the PDCCH CC, so that the PDSCH CC can be activated in time, and power can be saved more effectively.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for determining the activation state of a PDSCH CC. Background technique [0002] LTE (Long Term Evolution, long-term evolution) is the evolution of 3G (3rd Generation, third-generation digital communication), LTE improves and enhances 3G air access technology, adopts OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) ) and MIMO (Multiple Input Multiple Output, Multiple Input Multiple Output) as standards for the evolution of the LTE wireless network. Among them, in the LTE system and the previous wireless communication system, there is only one carrier in a cell, such as figure 1 As shown, the maximum bandwidth in the LTE system is 20MHz; and under the spectrum bandwidth of 20MHz, LTE can provide a peak rate of downlink 100Mbit / s and uplink 50Mbit / s, improve the performance of cell edge users, incr...
