Embodiment Construction

[0021] 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.

[0022] The present invention proposes to use RB start position, RB end position and subframe bitmap to indicate the resource position of uplink and / 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 bitmap}, which has no direct correspondence with the actually possibly adopted signaling format of the grant indication. 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 pos...

Abstract

The invention discloses an instruction method for scheduling authorized resources in an LTE TDD system, which comprises the steps as follows: wireless resource scheduling is started by a base station; a resource block range and a sub-frame bitmap are adopted as an authorized resource position instruction by the base station to generate scheduling authorized information containing the authorized resource position instruction which is transmitted to a terminal; the scheduling authorized information is received by the terminal and the authorized resource position instruction is extracted from the information by the terminal; data are received and transmitted by the terminal according to the authorized resource position instruction. Therefore, the authorized resource position is scheduled with the instruction of uplink and / or downlink by the using of the resource block range and the sub-frame bitmap of the invention, thereby not only obtaining lower expenditure for authorized instructive signaling, but also meeting the requirement of the system to the selective transmission of frequency.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically, to a method for indicating scheduling authorization resources in a 3GPP LTE TDD (Third Generation Partnership Project Long Term Evolution Time Division Duplex) system. Background technique [0002] LTE TDD system see figure 1 , mainly composed of terminals, base stations, and core networks. 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 non-access layer affairs, such as billing and location man...
