Transmission method and device for resource position field in resource allocation signaling

Abstract

The invention relates to a method for transmitting resource location field in resource assignment signaling and a device thereof. The method comprises the following steps: a base station determines the smallest size of the resource location field in the resource assignment signaling according to system bandwidth and width of guard band; the base station adds the information of the resource location to the resource assignment signaling according to the determined smallest size; the base station sends the resource assignment signaling in a downlink channel; the terminal gets the starting location and / or end location of authorization resource in an uplink channel and / or the downlink channel according to the resource assignment signaling. The device consists of a size determining module, an adding module for information of resource location and a signaling sending and receiving module. The method and the device of the invention can determine the size of the resource location field in the resource assignment signaling according to the situation of the system bandwidth so as to effectively improve the use efficiency of L1 / L2 control channel.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource location field transmission method and device in resource allocation signaling. Background technique [0002] The 3GPP LTE (Long Term Evolution of Third Generation Partnership) system is mainly composed of terminals, base stations and core networks, such as figure 1 shown. Among them, there can be logical or physical connections between base stations according to needs. The network composed of base stations is called RAN (Radio Access Network), which is responsible for access layer affairs, such as management of wireless resources; uplink and downlink wireless resources The base station is responsible for scheduling in a shared channel manner. The base station is connected to the core network. Each base station can be connected to one or more core network nodes (CN). The core network is responsible for non-access layer affairs, such as billing and location managemen...

Problems solved by technology

[0004] At present, 3GPP has not provided the format of the scheduling resource allocation signaling. It is certain that both the uplink and downlink scheduling grant indications must contain resource location fields to indicate the starting position of the grant resources.
