Embodiment 1

[0045] Embodiment 1 of the present invention provides a resource allocation method, such as figure 1 As shown, it is a schematic flowchart of the resource allocation method in Embodiment 1 of the present invention, and the resource allocation method may include the following steps:

[0046] Step 101: the base station receives the CQI fed back by each UE within its own coverage, and the CQI includes downlink channel state information of the UE.

[0047] Specifically, the CQI information can be periodically fed back by the UE, and if the CQI receiving time of the base station is not within the CQI feedback period of the UE, the CQI information received by the base station can refer to the CQI feedback value of the UE in the last period. Examples will not be described here.

[0048] Step 102: For any UE, according to the CQI fed back by the UE, obtain the first MCS of the UE through the AMC mechanism.

[0049] Specifically, the first MCS of the UE obtained through the AMC mecha...

Embodiment 2

[0108] Based on the same inventive concept, Embodiment 2 of the present invention provides a base station. For the specific implementation of the base station, refer to the relevant descriptions in Embodiment 1 of the above method, and the repetitions will not be repeated. For example, figure 2 As shown, it is a schematic structural diagram of the base station in Embodiment 2 of the present invention, and the base station may include:

[0109] The receiving module 21 can be used to receive the CQI fed back by each UE within the coverage of the base station, and the CQI includes downlink channel state information of the UE;

[0110] The processing module 22 can be used for any UE, according to the CQI fed back by the UE, obtain the first MCS of the UE through the AMC mechanism, and combine the obtained first MCS of the UE with the second MCS of the UE Performing a size comparison, wherein the second MCS of the UE is the lowest MCS determined by the base station according to th...

Abstract

The invention discloses a resource allocation method and a related apparatus. According to the resource allocation method and the related apparatus, a base station adaptively allocates proper modulation and coding schemes (MCS) and UE-level parameter PA values for UE according to the channel quality indicators (CQI) which are fed back by the UE in the coverage range of the base station and contain downlink channel state information, so as to satisfy the requirement of the quality of service (QoS) of the UE. Compared with an existing power equal allocation plan, the resource allocation method can select more suitable parameters such as MCS and power values for the UE so as to reduce network energy overhead.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a resource allocation method and related equipment. Background technique [0002] With the rapid development of mobile Internet traffic, the carrier frequency of LTE (Long Term Evolution, long-term evolution) network deployment will be very large, and because LTE is a high-bandwidth system and consumes a lot of power per carrier frequency, the entire LTE The network will cause huge energy consumption. However, since there is no effective energy-saving mechanism in the LTE downlink, how to achieve effective energy-saving in the LTE downlink to reduce the energy consumption of the LTE network has become an urgent problem to be solved in the commercial process of LTE. important question. [0003] Since in LTE downlink transmission, most of the RE (Resource Element, resource element) is occupied by PDSCH (Physical Downlink Shared Channel, physical downlink shared chan...
