Method and system for sending and receiving subframe coordination signaling applied to mobile network

Abstract

The invention provides a transmitting and receiving method and system of a sub-frame coordinate signal applied to a mobile network. The method provided by the invention comprises the steps of: grouping mobile equipment in a range covered by a macro base station by a transmitting system; next, generating the sub-frame coordinate signal required by each group based on a plurality of different power values of data transmitted by the macro base station in a non-zero almost blank sub-frame and transmitting the sub-frame coordination signal to the mobile equipment in the corresponding group; then determining the actual power of the data transmitted by each non-zero almost blank sub-frame by a receiving system based on the acquired sub-frame coordination signal and the power value of the data transmitted by each non-zero almost blank sub-frame in the sub-frame coordination signal. Thus, the micro base station outside the corresponding power coverage range can be effectively protected, so that more flexible scheduling between the macro base station and the micro base station covered by the macro base station is realized, and the transmitting power of unicast data is effectively reduced.

Description

technical field [0001] The invention relates to the field of communication in a hybrid network, in particular to a method and system for sending and receiving subframe coordination signaling applied to a mobile network. Background technique [0002] In future mobile communication systems, there will be application scenarios of mixed networks, that is, within the well-planned cellular network coverage formed by macro base stations, there will be coverage of multiple micro base stations. This enables certain areas to form a multi-layered network covered repeatedly by macro base stations and micro base stations. [0003] figure 1 It is a schematic diagram of a hybrid network transmission coverage scenario. Wherein, MeNB means a macro base station, MUE means a mobile device belonging to the MeNB base station; a pico base station. MUE1, MUE2, and MUE3 respectively represent mobile equipment within the coverage of the macro base station. Depend on figure 1 It can be seen that...

However, when a mobile device belongs to both group A and group B, the mobile device may receive two different subframe patterns at a certain moment. If it corresponds to a certain subframe, the subframes of the two different subframe patterns If the categories are different, the mobile device will not be able to identify whether the received transmit power is for a normal subframe or a non-zero quasi-blank subframe

[0011] In the above method, the power of the same base station to send unicast data to each group is the same, which makes the micro base station close to the base station more susceptible to interference, or the mobile device farther away from the base station cannot receive the unicast data sent with low power. data
