Problems solved by technology

It should be noted that, in principle, 3GPP LTE hopes that LTE FDD and LTE TDD will use the same scheduling grant indication signaling format, so this method of adding fields not only increases the signaling overhead, but it is also difficult to obtain support from 3GPP LTE

Embodiment Construction

[0020] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0021] The present invention proposes to use RB start position, RB end position and subframe information to indicate the resource position of uplink or downlink scheduling grant. For the convenience of description, this kind of authorized resource position indication is recorded as {RB start position, RB end position, subframe information}, which has no direct correspondence with the actually possibly used grant indication signaling format. The scheduling grant mentioned here can be for a certain UE, for a group of UEs, or for all UEs. The RB start position indicates the first RB position of the granted resource, and the RB end position indicates the last RB positio...

Abstract

The invention provides an indication method of dispatching authorized resources in a time division duplex system of long term evolution. A base station generates and sends dispatch and authorization information containing the position indication of authorized resource to a terminal. The indication method is characterized in that the position indication of authorized resource comprises resource block range and sub-frame information; and the sub-frame information comprises a sub-frame position or the initial position and the duration of the sub-frame; the total bit length of the sub-frame information is the same as the bit length of the duration in the long term evolution frequency division duplex system authorized resource position indication. The indication method utilizes a RB initial position, a RB final position and the sub-frame information to indicate the uplink or the downlink position of the dispatched and authorized resource, thereby acquiring lower authorization indication signaling overhead, enabling the authorization indication signaling forms of two systems of LET TDD and LTE FDD to be consistent, and meeting the requirement of the system for frequency selective transmission.

Description

technical field [0001] The present invention relates to an indication method for scheduling authorization resources applied to a 3GPP LTE TDD (Third Generation Partnership Project Long Term Evolution Time Division Duplex) system, and more specifically, relates to an indication method for scheduling authorization resources in an LTE TDD system. Background technique [0002] LTE TDD system see figure 1 , mainly composed of a terminal, a base station, and a core network. There can be logical or physical connections between base stations as required. The network composed of base stations is called a radio access network (RAN), which is responsible for access layer affairs, such as management of radio resources. The uplink and downlink radio resources are scheduled by the base station in a shared channel manner. The base station is connected to the core network, and each base station can be connected to one or more core network nodes (CN). The core network is responsible for n...
