Problems solved by technology

At this time, the user terminal also needs to decode its neighboring cells, which is more complicated to implement, and it is not enough to reduce the interference between cells only by considering the load introduced by neighboring cells

Embodiment Construction

[0026] In order to make the technical solutions provided by the embodiments of the present invention more clear, the technical solutions provided by the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] figure 1 It is a schematic flow chart of the method provided by the embodiment of the present invention. Before describing its specific steps, it is assumed in advance that the signal-to-noise ratio SINR of the reference signal is known ref , SINR ref The minimum value of the signal-to-noise ratio to meet the detection requirements of the reference signal.

[0028] Step 11, eNB (evolution Node B, evolved Node B, a kind of base station equipment) measures the average interference plus noise of the cell according to the uplink average interference plus noise of each user terminal, and calculates the average interference plus noise obtained by the measurement and uplink load reported to the gateway (GW)...

Abstract

An embodiment of the invention relates to the communication field, and especially relates to a wireless communication field. The invention provides a method for obtaining the transmitting power of the ascending data and an apparatus thereof. The transmission power of the reference signal is obtained according to the attrition of the descending path and the least value of the signal-to-noise ratiosatisfying to the requirement for detecting the reference signal. The emission power of the ascending data is obtained according to the transmission power of the reference signal. The electric quantity of the battery of the user terminal is saved. The attrition and shade decay of the data in the ascending path is compensated, and at the same time the mutual interference between the subdistricts are restrained to lead to that the control to the emission power of the ascending data is more accurate.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and equipment for acquiring uplink data transmission power. Background technique [0002] In the LTE (Long Term Evolution) system, the uplink and downlink systems divide frequency resources into resource units (RUs) and physical resource blocks (PRBs). 12 subcarriers, or 300kHz. The uplink RU can be divided into Localized RU (LRU, centralized resource unit) and Distributed RU (DRU, distributed resource unit). The LRU contains a group of adjacent subcarriers, and the DRU contains a group of dispersed subcarriers. In order to maintain the single-carrier signal format, if a user terminal (UE) occupies multiple LRUs, these LRUs must be adjacent; if multiple DRUs are occupied, all subcarriers must be equally spaced. [0003] For the LRU mapping method, the UE first needs to send reference signals on different frequency resources (ie channels) before sending data, and selec...
