Embodiment 1

[0266] An embodiment of the present invention provides a method for MBSFN configuration, specifically as figure 2 As shown, the method includes:

[0267] 201. The base station determines the subframe configuration of the MBSFN subframe used to bear the PMCH, where the subframe configuration includes: CP type and / or reference signal pattern.

[0268] Wherein, the CP type includes: a normal CP, an extended CP or other CPs, and the length of the other CP is different from that of the normal CP and the extended CP.

[0269] Specifically, in the MBSFN configuration method provided by the embodiment of the present invention, the base station first determines the subframe configuration of the MBSFN subframe used to carry the PMCH, which can be implemented in the following two ways:

[0270] In a first possible implementation manner, the base station uses a preset subframe configuration of the MBSFN subframe, and the preset subframe configuration of the MBSFN subframe is determined ...

Embodiment 2

[0435] An embodiment of the present invention provides a method for MBSFN configuration, specifically as Figure 40 As shown, the method includes:

[0436] 4001. The UE receives MBSFN configuration information, wherein the MBSFN configuration information is used to indicate the subframe configuration of the MBSFN subframe carrying the PMCH, and the subframe configuration includes: CP type and / or reference signal pattern.

[0437] Wherein, the CP type includes: a normal CP, an extended CP or other CPs, and the length of the other CP is different from that of the normal CP and the extended CP.

[0438] Specifically, in the MBSFN configuration method provided by the embodiment of the present invention, the UE first receives MBSFN configuration information, and the configuration information is used to indicate the subframe configuration of the MBSFN subframe carrying the PMCH.

[0439] Wherein, the MBSFN configuration information may be carried in the RRC signaling and carried in...

Embodiment 3

[0484] An embodiment of the present invention provides a base station 4100, specifically as Figure 41 As shown, the base station 4100 includes: a determining unit 4101 and a sending unit 4102 .

[0485] The determining unit 4101 is configured to determine a subframe configuration of an MBSFN subframe used to carry a PMCH, where the subframe configuration includes: a CP type of a cyclic prefix, and / or a reference signal pattern.

[0486] Wherein, the CP type includes: a normal CP, an extended CP or other CPs, and the length of the other CP is different from that of the normal CP and the extended CP.

[0487] The sending unit 4102 is configured to send the MBSFN configuration information determined by the determining unit 4101 to a user equipment UE, where the MBSFN configuration information is used to indicate the subframe configuration of the MBSFN subframe.

[0488] Preferably, here are two possible implementations for the determining unit 4101 to determine the subframe con...

Abstract

Embodiments of the present invention provide a method and device for MBSFN configuration, which can realize flexible configuration of MBSFN and improve the utilization rate of wireless resources of the system. The method includes: the base station determines the subframe configuration of the MBSFN subframe used to carry the physical multicast channel PMCH, the subframe configuration includes: a cyclic prefix CP type, and / or, a reference signal pattern; the base station sends the user equipment The UE sends MBSFN configuration information, the MBSFN configuration information is used to indicate the subframe configuration of the MBSFN subframe; wherein, the CP type includes: normal CP, extended CP or other CP, and the length of the other CP is different from the Describe the lengths of normal CP and extended CP. The invention is applicable to the communication field.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and equipment for MBSFN configuration. Background technique [0002] Currently, in a long term evolution (long term evolution, LTE) system, the structure of a radio frame is: a radio frame includes 10 subframes, and each subframe includes 2 slots. Normally, the time slots in 10 subframes are represented by the numbers of No. 0, No. 1, No. 2, ..., No. 18, and No. 19, that is to say, when subframe No. Slot and No. 1 time slot, No. 1 subframe consists of No. 2 time slot and No. 3 time slot, ..., No. 9 subframe consists of No. 18 time slot and No. 19 time slot. [0003] Orthogonal Frequency Division Multiplexing (OFDM) technology is used in the downlink transmission of the LTE system. In the OFDM technology, a guard interval or a cyclic prefix (Cyclic Prefix, CP) may be added before each OFDM symbol to eliminate intersymbol interference caused by signal multipath. Curren...
