Method for indicating sub-frame property in time division multiplexing system of long-term evolution network

Abstract

The invention provides a method for indicating sub-frame property in a time division multiplexing (TDD) system of a long-term evolution (LTE) network. The MBSFN indication bits are written in the message SI-1 of system information of system broadcast message of multi-broadcast/broadcast MBSFN frames on each single-frequency network of an improved E-Universal Terrestrial Radio Access Network; and the MBSFN indication bit is used for indicating whether the sub-frame of the MBSFN frame of the LTE TDD is an MBSFN sub-frame. The method indicates whether each sub-frame of the wireless frame adopts the MBSFN by allocating the MBSFN indication bit at the SI-1 of each MBSFN frame in the TDD system of the LTE, thus leading the UE to adopt the MBSFN reference signal or the reference signal specially used by the district on each sub-frame to carry out channel estimation.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for indicating subframe attributes in a TDD (Time Division Duplex, time division duplex) system of an LTE (Long Term evolution, long term evolution) network. Background technique [0002] In 2005, 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) launched a working group for LTE research to study and design a 3.9G (improved 3G) next-generation network that is an evolution of the third-generation mobile communication technology. The overall goals of its design are: [0003] ●Simple system structure [0004] ●Higher transmission rate [0005] ●Low overall cost [0006] ●Economic and good backward compatibility [0007] ●Flexible use of spectrum [0008] ●Flexible business support capability [0009] At the 3GPP meeting in November 2007, two LTE physical layer frame structures of FDD (Frequency Division Duplex) and TDD were det...
