Embodiment Construction

[0024] Embodiments of the present invention provide a resource allocation method and device to realize reasonable allocation of D-SR resources, and further dynamically adjust the size of D-SR resources according to system load and other conditions, so as to improve the utilization rate of PUCCH resources.

[0025] The system will reserve a part of PUCCH resource as the dedicated scheduling request resource of the cell, that is, the D-SR resource, and the size of the resource can be notified to each UE by broadcasting a message in the cell. The embodiment of the present invention proposes a semi-static allocation scheme for D-SR resources, which realizes determining the amount of D-SR resources of a cell from the reserved PUCCH resources, that is, determining the amount of each uplink regular sub-unit of each SR cycle. How many D-SRs of UEs can be carried by the PUCCH channel in the frame.

[0026] It should be noted that the D-SR resource allocation mentioned in the embodiment...

Abstract

The invention discloses a resource allocation method and a resource allocation device for realizing the allocation of a D-SR resource. The resource allocation method provided by the invention comprises the following steps of: determining a number average value UE_NUM_AVG of user equipment UE in a synchronous state in each uplink conventional subframe in a preset time interval; according to configuration information of an uplink or a downlink, determining the number NUM of the uplink conventional subframes in each scheduling request SR period; and determining a number value of the UE which canbe loaded by a physical uplink control channel in each uplink conventional subframe of each SR period by utilizing the UE_NUM_AVG and the NUM and using the number value of the UE as a value of the dedicated scheduling request D-SR resource in each uplink conventional subframe of each SR period.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a resource allocation method and device. Background technique [0002] The Long Term Evolution (LTE) system is a scheduling-based communication system. If there is data to be sent in the transmission buffer of the user equipment (UE), the UE needs to send a buffer status report (BSR, buffer status) to the evolved base station (eNB) first. report), notifying the eNB of the data information that needs to be sent in the current sending buffer of the UE. After receiving the BSR sent by the UE, the eNB allocates corresponding uplink shared channel (UL-SCH) resources for the UE according to the amount of data that the UE needs to send, and notifies the UE to send data on the allocated UL-SCH resources. [0003] The UE also needs to use UL-SCH resources to send BSR to the eNB. If the UE has a BSR to report, but there is no UL-SCH resource allocated for itself at this t...
