Embodiment Construction

[0083] The inventors found that the existing technical solution is only a simple integration of Femtocell and WiFi. Uplink and downlink communication is performed between MeNB and MUE (Macro UE, MeNB user) within the coverage area of ​​MeNB; i-Femtocell also exists within the coverage area of ​​MeNB, and uplink and downlink communication is performed between i-Femtocell and HUE within the coverage area of ​​i-Femtocell communication. i-Femtocell refers to a base station with both HeNB and WLAN communication standards. The part of i-Femtocell that implements the HeNB communication standard is collectively referred to as the HeNB side, and the part of i-Femtocell that implements the WLAN communication standard is collectively referred to as the WLAN side.

[0084] Figure 1a Shown is a hotspot scenario in the HetNet network after Femtocell and WiFi integration, the uplink communication between MeNB and MUE may cause interference to the uplink communication between HeNB side and ...

Abstract

The application discloses a resource scheduling method and device. The method comprises that: at least one first HUE in one set of HUEs is judged according to the preset condition, an HUE first set is formed by the at least one first HUE, and total number n1 of first RBs occupied by all the HUEs in the set is confirmed; if the total number n2 of idle RBs is not less than n1, n1 idle RBs are selected from the n2 idle RBs, and the selected n1 idle RBs are allocated for the HUEs in the HUE first set; when n2 is less than n1, n3 HUEs are selected from the HUE first set, m0 idle RBs are selected from the n2 idle RBs, and the selected m0 idle RBs are allocated for the n3 HUEs; and (n1-m0) first RBs are selected from the n1 first RBs, and the selected (n1-m0) first RBs are allocated for the HUEs apart from the n3 HUEs in the HUE first set.

Description

technical field [0001] The present application relates to the communication field, and in particular to a resource scheduling method and device. Background technique [0002] With the development of mobile communication technology, especially the proposal of the fourth-generation cellular mobile communication system International Mobile Telecommunications-Advanced (IMT-A, International Mobile Telecommunications-Advanced), how to support higher-speed data transmission to meet the growing data traffic Network requirements for multimedia services and multimedia services have become urgent problems for mobile communication networks. [0003] In the cellular mobile communication system, in addition to increasing the transmission bandwidth, using high-order modulation and multiple input multiple output system (MIMO, Multiple Input Multiple Output), small cellular home base stations (Femtocell), pico cells (Picocell), Relay Another solution to this problem is proposed in technolog...
