Problems solved by technology

[0004] In order to reduce the interference of data on the reference signals of adjacent cells and improve the accuracy of channel estimation, the REs that collide with the REs where the reference signals of adjacent cells are located can be punctured. However, there is currently no solution for energy notification after puncturing.

Embodiment Construction

[0027] Such as figure 1 Shown is a transmission energy notification method provided by an embodiment of the present invention, including:

[0028] S101: Perform transmit energy reduction on the resource units of the own cell that have the same time-frequency position as some or all of the resource units where the reference signal of the neighboring cell is located;

[0029] Among them, energy reduction is only performed on some resource elements (Resource Element REs) that collide with the reference signal of the adjacent cell, that is, the part of REs that have the same time-frequency position as the reference signal of the adjacent cell, so that the resource elements (DREs) that perform transmission energy reduction can be reduced. ) to increase the number of available REs that can be used for normal data transmission or other purposes.

[0030] For energy reduction, specifically, the transmission energy of the resource units of this cell that have the same time-frequency p...

Abstract

The invention discloses an emitted energy notification method and device. The method includes the steps of conducting emitted energy reduction on resource units, with the same time-frequency positions as a part of or all resource units where parameter signals of a neighbor cell are located, of a cell, obtaining emitted energy parameters of resource units NRE, where no energy reduction is conducted, of the cell according to the reduction amount of emitted energy of the resource units DRE where emitted energy reduction is conducted, and reminding user equipment UE of the emitted energy parameters of the NRE. By means of the emitted energy notification method and device, emitted energy can be prevented from being wasted, emitted energy of a part of the REs is improved, and then the SINR and throughput of service data can be increased.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for notifying transmission energy. Background technique [0002] The fourth-generation mobile communication system can provide higher peak user throughput, average user throughput and edge user throughput, giving users a better data transmission experience. [0003] Coordinated multipoint processing (CoMP) is introduced in the fourth generation mobile communication system for higher user throughput. In a CoMP scenario, multiple cells simultaneously provide data transmission services for a UE. Different from the traditional single-cell service, in the CoMP scenario, the user equipment UE needs to measure the reference signals sent by multiple serving base stations at the same time, and estimate the downlink channel information from multiple base stations and feed them back. [0004] In order to reduce the interference of data on adjacent cell reference...
