Problems solved by technology

However, part of the parameter information delivered by the network side is dynamic parameter information (for example: the transmission mode of the interfering cell). Dynamic parameter information will become static parameter information, making the network side lose flexibility in configuring this part of dynamic parameter information
[0003] To sum up, in the prior art, when the network side delivers the parameter information of the interfering cell to assist the UE to suppress or delete the interference of adjacent cells, if the network side downloads part of the dynamic parameter information (for example: the transmission mode of the interfering cell) Sending to the UE will cause the network side to lose flexibility

Embodiment Construction

[0034] The specific implementation manners of a method and an apparatus for determining a transmission mode provided in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] It should be noted that in the LTE-A Rel-12 system, the network side (for example: the base station) will issue the interfering cell identifier (Identifier, ID), the number of common reference signal ports, PB, PA subset and other information, based on these Information, combined with the received signal and channel estimation, can perform blind detection of the transmission mode of the interfering cell. At the same time, the base station will issue various transmission modes supported by the interfering cell. The set of transmission modes supported by the interfering cell can be: {TM1, TM2, TM3, TM4, TM6, TM8, TM9}. In the current network environment, the number of CRS ports is 2, and the transmission mode set usually implemented b...

Abstract

The invention discloses a method and device for determining a transmission mode, which are used to determine the transmission mode of an interfering cell according to acquired parameter information, to realize blind detection of the transmission mode of the interfering cell, without sending the transmission mode of the interfering cell from the network side, Improve flexibility on the network side. The method for determining the transmission mode includes: acquiring parameter information for determining the transmission mode of the interfering cell; and determining the transmission mode used by the interfering cell according to the parameter information.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for determining a transmission mode. Background technique [0002] In the Long Term Evolution Advanced (LTE-A) version 12 (Rel12) system, in order to improve the system throughput in the interference scenario, the network side will send some parameter information of the interfering cell to the user equipment (User Equipment, UE), assisting the UE to suppress or delete adjacent cell interference (NetworkAssisted Interference Cancellation and Suppression, NAICS). However, part of the parameter information delivered by the network side is dynamic parameter information (for example: the transmission mode of the interfering cell). The dynamic parameter information will become static parameter information, so that the configuration of the dynamic parameter information on the network side loses flexibility. [0003] To sum up, in the prior art, whe...
