Problems solved by technology

[0053] The disadvantage of the prior art is that when there are unused subframes (MBMS transmission) in the MBSFN subframes corresponding to a certain MCH indicated by the system, since users performing unicast data transmission usually do not listen to these subframes Therefore, these subframes cannot be used to send unicast data, and the resources on these subframes will be wasted

Embodiment Construction

[0090] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0091] The inventor noticed during the invention that in the LTE system, users who do not receive MBMS transmission do not monitor MBMS scheduling information. In addition, even users who receive MBMS services only monitor the scheduling information on the MCH corresponding to the received service. Therefore, when subframes not used for MBMS transmission appear on some MCHs, even if these subframes can be used to send other non-MBMS data, since ordinary unicast users do not monitor MBSFN subframes by default, the above-mentioned users It is not clear which MBSFN subframes in which period of time will transmit unicast data, nor can these subframes be used to send data for these users. Figure 6 It is a schematic diagram of the MBSFN subframe corresponding to the MCH, such as Figure 6 As shown in , the subframes represented in grid form are the subframe...

Abstract

The invention discloses method and equipment for receiving and transmitting scheduling information. The method comprises the steps of: determining an idle MCH (Multicast Channel) or PMCH (Physical Multicast Channel), wherein the idle MCH or PMCH has an idle MBSFN (Multicast Broadcast Single Frequency Network) subframe; determining an indication MCH or PMCH, wherein the indication MCH or PMCH and the idle MCH or PMCH are positioned in the same MBSFN region; carrying indication information in scheduling information corresponding to the indication MCH or PMCH, wherein the indication information comprises whether an MCH or PMCH in the indication MBSFN region is an idle MCH or PMCH, and / or resource positions of idle MBSFN subframes on the indication idle MCH or PMCH; and sending the schedulinginformation on the indication MCH or PMCH. By using the invention, user equipment can obtain information of an idle MBSFN subframe, and can avoid the waste of wireless resources on the idle MBSFN subframe.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and device for sending and receiving scheduling information. Background technique [0002] 1. MBMS (Multimedia Broadcast / Multicast Service) technical overview. [0003] MBMS technology is used to provide multimedia broadcast and multicast services to users in wireless cells. MBMS can perform single-cell transmission or multi-cell transmission. MBMS single-cell transmission means that MBMS is only transmitted within the coverage of a designated cell, and does not support the combination of MBMS transmissions from other cells; MBMS multi-cell transmission uses MBSFN (Multicast Broadcast Single Frequency Network, multicast broadcast single frequency network ) transmission mode, that is, a transmission mode in which exactly the same content is simultaneously transmitted in multiple cells at the same time and at the same frequency, and a UE (User Equipment, user equipm...
