Embodiment 1

[0036] Depend on figure 1 As shown, this embodiment relates to a wireless in-band backhaul resource allocation application system, which includes a macro base station, a small base station, and a terminal. Wherein, the macro base station forms the allocation of frequency band resources, such as setting resource boundary lines, so as to allocate the frequency band resources. The small base station communicates with the macro base station through a backhaul link session, and the small base station is assigned an identifier to be identified by the macro base station, where the identifier can be a bit or a character string. Backhaul frequency band resources from a high frequency band to a low frequency band are allocated between the small base station and the macro base station due to the backhaul link.

[0037] The terminal communicates with the macro base station through a macro base station access link session, or communicates with the small base station through a small base s...

Embodiment 2

[0040] This embodiment relates to a method for allocating wireless in-band backhaul resources, and the method includes the following steps:

[0041] Frequency band resource allocation step: the macro base station demarcates the frequency band resources to determine the resource allocation scheme;

[0042] Allocation of backhaul frequency band resources: the macro base station receives the request from the small base station, and allocates backhaul frequency band resources from high frequency band to low frequency band to the small base station with the identification according to whether the small base station has an identifier;

[0043] The macro base station access frequency band resource allocation step: the macro base station simultaneously receives the terminal's access request, and allocates the macro base station access frequency band resources to the terminal according to the principle of from low frequency band to high frequency band;

[0044] The small base station a...

Abstract

The invention relates to a wireless in-band backhaul resources allocation application system and resources allocation method. The wireless in-band backhaul resources allocation application system comprises a macro base station ,a small base station and a terminal; the small base station communicates with the macro base station through the backhaul link, and the small base station is endowed with an identifier to be recognized by the macro base station; the backhaul band resources from the high frequency band to the low frequency band are allocated between the small base station and the macro base station because of the backhaul link; and the terminal communicates with the macro base station through the macro base station accessing link, or communicates with the small base station through the small base station accessing link. By means of the wireless in-band backhaul resources allocation application system, the backhaul of the small base station is realized by means of the in-band spectrum, the resource conflicts and the mutual interference can be effectively reduced, and the utilization ratio of spectrum resources is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a wireless in-band backhaul resource allocation application system, and at the same time, the invention also relates to a wireless in-band backhaul resource allocation method. Background technique [0002] Existing, with the gradual shortage of spectrum resources, the use and allocation of spectrum resources become particularly important. In the CN201510470746.3 patent, it is disclosed that a macro base station is used to collect the channel state information of the self-backhaul link channel to all small base stations and the access link channel from the small base station to the user, using virtual full cooperation method and interval elimination In this method, the group-sparse precoding matrix is ​​obtained through alternate iterations, and the joint design of self-resource allocation and access link precoding is realized. [0003] In the 201410064699.8 patent...
