Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a system for issuing coordination information.
Background
With the increasing requirements on data rate and service load, the access provided by the traditional method of adopting macro base station single-layer coverage cannot meet the use requirements, so that the access is provided by adopting a layered coverage method at present, that is, some low-power micro base stations (such as HeNB, Pico, Femto, Relay and the like) are deployed in a hot spot area or indoors and cooperate with the macro base station to complete the access. The so-called micro base station is a base station device applied in a home indoor environment, an office environment or other hot spot small coverage environments, and can provide services with higher data rate and lower cost.
At present, for the interference problem of the micro base station, a time domain scheme is adopted to solve, as shown in fig. 1, under the prior art, the adopted time domain scheme is as follows: the interference base station such as the micro base station does not send data on certain subframes, so that interference to the macro base station of the interfered base station is avoided.
The premise of adopting the time domain scheme is that both the macro base station and the micro base station need to know which subframes the micro base station needs to send data on, and which subframes the micro base station does not send data on, namely, the coordination information of the micro base station is clear. In order to solve the above problems, the currently proposed implementation scheme is as follows: and adopting an X2 interface or an S1 interface to perform interaction or coordination of the coordination information of the micro base station.
Taking macro base station as eNB and micro base station as home base station (HeNB) as an example, referring to fig. 2, an X2 interface is provided between enbs, an S1 interface is provided between eNB and Mobility Management Entity (MME), HeNB may be directly connected to MME, or may be accessed to MME through a relay node [ e.g., home base station gateway (HeNB GW) ], HeNB may be connected to only one HeNB GW at the same time, and an S1 interface is provided between HeNB and HeNB GW; the current scheme provides that coordination information can be exchanged between the eNB and the HeNB through an X2 interface or an S1 interface, so as to coordinate the configuration of subframes or coordinate the process of power control.
However, in the current 3GPP specification, it is not defined whether an X2 interface is provided between the HeNB and the neighboring HeNB or eNB, and therefore, the method for the HeNB to obtain the coordination information through the X2 interface is not feasible in the above scheme; the method of interacting the coordination information through the S1 interface has the problems of time delay, signaling overhead, etc., and is not an optimal solution
In view of the above, a new method is needed to enable the micro base station to obtain the coordination information in time to coordinate the subframe pattern.
