Problems solved by technology

If the base station can be turned off for a long enough time, the energy saving of the base station and the improvement of power amplifier efficiency will be very obvious; but if the radio frequency is turned off, it means that the base station can no longer send any information, so it is not enough to save power only by turning off the radio frequency Perfect, it cannot not only guarantee the data transmission of the user equipment but also save power and energy

Embodiment Construction

[0040] The basic idea of ​​the present invention is: the base station converts the unicast subframe into a multimedia broadcast multicast service single frequency network (MBSFN) subframe, and then, the base station sends the configuration signaling of the converted MBSFN subframe to the user equipment (UE).

[0041]The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] There are two subframes in LTE: one is MBSFN subframe, and the other is non-MBSFN subframe; Among them, non-MBSFN subframe is generally used to transmit unicast service data, and CRS is sent in each subframe, according to the relevant agreement It is stipulated that CRS needs to be sent even when there is no unicast service data; MBSFN subframes are mainly used to transmit Multimedia Broadcast Multicast Service (MBMS, Multimedia Broadcast Multicast Service), and a small amount of MBSFN subframes are also used to transmit oth...

Abstract

The invention discloses a subframe configuring method. The method comprises the following steps that: a base station reconfigures a unicast subframe into a multimedia broadcast single frequency network (MBSFN) subframe; and the base station sends a configuring signaling of the reconfigured MBSFN subframe to user equipment (UE). The invention also discloses a subframe configuring system. By the method and the system, the transmission of unicast service is not affected and the base station saves electricity and energy.

Description

technical field [0001] The invention relates to the field of base stations in a mobile communication long-term evolution system, in particular to a subframe configuration method and system. Background technique [0002] In mobile communication, the power consumption of user equipment (UE, User Equipment) is very important. Universal Terrestrial Radio Access Network (UTRA, Universal Terrestrial Radio Access Network) and Evolved Universal Terrestrial Radio Access Network (E-UTRA, Evolved Universal Terrestrial RadioAccess Network) and others have developed efficient discontinuous transmission (DTX, Discontinuous Transmission) and discontinuous reception (DRX, Discontinuous Reception) technologies to reduce power consumption and achieve the purpose of energy saving. [0003] The so-called DTX technology refers to that in a communication process, because the mobile user actually only spends a little time for talking, and most of the time does not transmit voice messages, when the...
