Method and station of resource distribution

Abstract

The invention discloses a method and a station of resource distribution. The method and the station are used for distribution of resource blocks by the station. The method includes that the station confirms a user device UE distributed by the distribution resource blocks at present; if a reference number of any one resource block of the distributed resource blocks of the UE is located in a preset first reference number range, whether the number of the distributed resource blocks of the UE is less than a preset first parameter value; and if the number of the distributed resource blocks of the UE is less than the preset first parameter value, scheming priority of the UE is improved, the next distributed resource block is distributed to the UE, and alternatively, the resource blocks having the reference numbers which are located in the preset first reference number range are deleted from the distributed resource blocks of the UE. The method can effectively reduce the maximum value of out-of-band radiation power spectrum density of the UE, reduces interference of adjacent frequency ranges, and improves system performance.

Description

technical field [0001] The present invention relates to a wireless communication system, in particular to a resource allocation method and a base station. Background technique [0002] In the Long Term Evolution (LTE, Long Term Evolution) standard, for Orthogonal Frequency Division Multiplexing (OFDM, Orthogonal Frequency Division Multiplexing), a method for allocating bandwidth resources in two dimensions of time domain and frequency domain is proposed. [0003] A bandwidth resource block is composed of time domain and frequency domain, referred to as resource block (RB, Resource Block). For OFDM-based systems, RB is the minimum physical resource allocated to users by the system. In LTE, an RB is defined It is the time of 14 OFDM symbols in the time domain, and the width of 12 subcarriers in the frequency domain, where the interval of each subcarrier is 15KHz, so the minimum resource block size allocated to a user is 14(OFDM)*12(subcarrier carrier). [0004] In the prior ...

Problems solved by technology

However, in the LTE system, when the base station operates in adjacent frequency bands at the same time, due to the imperfection of UEs, UEs operating on two adjacent frequency bands will experience coexistence interference, and UEs are prone to produce out-of-band radiation when sending useful signals. External radiation includes adjacent frequency radiation and out-of-band spurious radiation caused by modulation, and when the UE receives useful signals, the interference signal falling into the channel may cause the loss of UE receiving sensitivity and the interference signal falling into the receiving bandwidth may in-band blocking

[0005] In order to ensure that UE-to-UE interference will not cause significant performance loss to the interfered UE, it is necessary to limit the out-of-band radiation power spectral density of the UE so that the maximum value of the out-of-band radiation power spectral density of the UE is smaller than the allowable band of the adjacent frequency band. The maximum value of the external radiation power spectral density. In the prior art, in order to reduce the out-of-band radiation power spectral density of the UE, the base station will send control signaling to all UEs in the system, requiring all UEs in the system to reduce the maximum transmit power. It reduces the out-of-band radiation interference to UEs operating on adjacent frequency bands. However, reducing the maximum transmit power of all UEs in the system will affect the uplink coverage of the system, which has a great impact on network planning and has little implementability.
