Resource allocation method, base station and user end

Abstract

The invention provides a resource allocation method, a base station and a user end. The method comprises the steps: after allocating a semi-continuous resource for the user end (UE), the base station sends a resource allocation resource to the UE by a control information channel, wherein, if confirmation information which is fed back after the UE obtains the resource allocation resource is received, the resource allocation to the UE at this time is conformed to be successful, otherwise, the resource allocation to the UE at this time is conformed to be unsuccessful. The invention can effectively solve the problem of resource waste or resource conflict as the UE has no correct decoding control channel in the continuous packet connection (CPC) technology.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a resource allocation method, a base station and a user terminal. Background technique [0002] With the development of mobile communication systems, users have higher and higher requirements for mobile communication performance. In order to improve uplink and downlink communication capabilities, the third generation mobile communication standardization partnership project (3GPP, 3 rd The Generation Partnership Project) organization proposed a High Speed ​​Uplink Packet Access (HSUPA, High Speed ​​Uplink Packet Access) technology and a High Speed ​​Downlink Packet Access (HSDPA, High Speed ​​Downlink Packet Access) technology. [0003] In HSPUA technology and HSDPA technology, the base station (NodeB) on the network side needs to allocate the resources used by the UE to receive or send data for the user terminal (UE) through the control channel, and the valid...

Problems solved by technology

[0004] However, the following problems may exist in the implementation of the above CPC technology: after the NodeB adjusts the allocated resources for the UE through the control channel, if the UE does not correctly decode the control channel, it will still send or receive data according to the resources before the adjustment , and the NodeB will receive or send data for the UE according to the adjusted resources, so the inconsistency between the two sides will lead to a lot of waste of resources or resource conflicts

Taking VoIP uplink transmission as an example, when the NodeB increases the resources allocated to the UE through the E-AGCH, if the UE does not correctly decode the E-AGCH, it will still send uplink data according to the resources originally allocated to it, and the NodeB thinks it has Allocate the resource to the UE instead of scheduling the increased part of the resource to other UEs, which causes a waste of resources

When the NodeB reduces the resources allocated to the UE through the E-AGCH, if the UE does not decode the E-AGCH correctly, it will still send uplink data according to the resources originally allocated to it, and the NodeB believes that the UE has released part of the occupied resources , so this part of resources is allocated to other UEs, which will cause multiple UEs to use the same resources, causing resource usage conflicts
