Embodiment 1

[0050] In the LTE system, in addition to the conventional subframe, a downlink MBSFN subframe is also defined. The characteristic of the MBSFN subframe is that the MBSFN subframe is divided into a non-MBSFN subframe area and an MBSFN subframe area. Further, the non-MBSFN subframe area is one or two normal (normal) CP (Cyclic Prefix, cyclic prefix) OFDM symbols, which are used to transmit control channels. The CP type of the OFDM symbol in the MBSFN subframe area can be specified. If the multicast service is transmitted in the MBSFN subframe area, the extended CP will be used; if the unicast service is transmitted in the MBSFN subframe area, the normal CP will be used; For regional transmission of positioning reference signals, use normal CP or extended CP.

[0051] Aiming at the problems existing in the prior art, Embodiment 1 of the present invention proposes a processing method for turning off symbols. In the embodiment of the present invention, the characteristic that the ...

Embodiment 2

[0079] Based on the same inventive concept as the above method, an embodiment of the present invention also provides a base station device, such as Figure 5 As shown, the base station equipment specifically includes:

[0080] The determination module 11 is used to count the load situation of the cell, and use the load situation of the cell to determine that the base station equipment currently needs to perform symbol off processing on the MBSFN subframe of the multimedia broadcast multicast service single frequency network;

[0081] Judging module 12, for judging whether to need to increase MBSFN subframe number at present;

[0082] The configuration module 13 is configured to configure the regular subframe as an MBSFN subframe when the judgment result is yes;

[0083] The processing module 14 is configured to perform symbol off processing on the MBSFN subframe.

[0084] The determining module 11 is specifically used to judge whether the load of the cell is less than the lo...

Abstract

The invention discloses a symbol turn-off processing method and equipment. The symbol turn-off processing method includes that base station equipment counts the cell loading situation and confirms that the base station equipment needs to carry out symbol turn-off processing on an MBSFN sub-frame at present according to the cell loading situation; the base station equipment judges whether the MBSFN sub-frame number needs increase at present; if so, a normal sub-frame is configured into the MBSFN sub-frame, and the symbol turn-off processing is carried out on the MBSFN sub-frame. According to the embodiment, the normal sub-frame is configured into the MBSFN sub-frame, the symbol turn-off processing is carried out on the MBSFN sub-frame, and therefore, more symbol turn-off processing is realized, and the power consumption is further lowered.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a processing method and equipment for turning off symbols. Background technique [0002] Today, when green environmental protection has become a hot topic in the world, the green and energy-saving technology of wireless communication systems has become the core issue faced by mobile communication technology. The key point of wireless communication network energy saving is the access network, and the energy saving of base station equipment and supporting energy saving are the key. As the carrier of the wireless communication network, base station equipment needs to maintain high-quality coverage capabilities on the one hand, and ensure sufficient upgrade and evolution potential on the other hand. With the increase of the number of users and business volume, a large amount of energy is consumed, and simply reducing the number of base station equipment will lead t...
