Embodiment Construction

[0096] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0097] image 3 It is a schematic diagram of the implementation flow of the method for determining the component carrier and the initiation time for initiating random access. As shown in the figure, the following steps may be included in the congestion control:

[0098] Step 301, the eNB determines the BI for each uplink component carrier of the UE;

[0099] Step 302, the eNB carries the BI for each uplink component carrier of the UE in the random access response message;

[0100] In step 303, the UE determines the uplink component carrier to initiate random access next time and the initiation time according to the BI of each uplink component carrier in the random access response message.

[0101] From the above steps, it can be seen that steps 301 and 302 are processing performed by the eNB side, and step 303 is processing performed by the UE side, w...

Abstract

The invention discloses a method and equipment for determining member carrier initiating random access and initiating time. The method comprises: an evolution base station determines a retroversion instruction aiming at each uplink member carrier of user equipment; the evolution base station carries the retroversion instruction aiming at each uplink member carrier of the user equipment in a random access response message; and the user equipment determines the uplink member carrier and the initiating time for initiating next random access according to the retroversion instruction of each uplink member carrier in the random access response message. The invention can overcome the defect that the prior art only can realize congestion control on single member carrier; the invention can better solve the problem of random access congestion control between the carriers of a multiple-member carrier system and improves the random access success rate of the whole system.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method and equipment for determining a component carrier and an initiation time for initiating random access. Background technique [0002] 1. Brief introduction of carrier aggregation mechanism: [0003] The peak rate of LTE-A (Long Term Evolution-Advanced, enhanced long-term evolution system) is greatly improved compared with LTE (Long Term Evolution, long-term evolution), and it is required to reach 1Gbps downlink and 500Mbps uplink. At the same time, the LTE-A system requires good compatibility with the LTE system, and the maximum bandwidth of the LTE system is 20MHz. The LTE-A system introduces a CA (Carrier Aggregation, Carrier Aggregation) technology based on the need to increase the peak rate, be compatible with the LTE system, and make full use of frequency resources. [0004] Carrier aggregation technology refers to the uplink and downlink of a cell conta...
