Problems solved by technology

The PDSCH corresponding to each SC-MTCH can share the same P B , but due to the particularity of the MBMS service, the PDSCH corresponding to the SC-MTCH uses P B may be different from the P of ordinary PDSCH B
[0004] Since the PDSCH corresponding to SC-MCCH and SC-MTCH is a special PDSCH, the power of PDSCH corresponding to SC-MCCH and SC-MTCH cannot be set by using the existing PDSCH transmission power setting method

Embodiment Construction

[0023] figure 1 It is a flowchart of a method for setting PDSCH power in SC-PTM provided by an embodiment of the present invention. The embodiment of the present invention aims at that the PDSCH corresponding to SC-MCCH and SC-MTCH is a special PDSCH, therefore, the power of PDSCH corresponding to SC-MCCH and SC-MTCH cannot be set by using the existing PDSCH transmission power setting method, and provides SC- PDSCH power setting method in PTM, the specific method steps are as follows:

[0024] Step S101. Determine first identification information and second identification information of a physical downlink shared channel PDSCH corresponding to a single-cell multimedia broadcast multicast service control channel SC-MCCH.

[0025] Step S102, according to the transmission power of the cell reference signal, the first identification information and the second identification information of the PDSCH corresponding to the SC-MCCH, determine the transmission power of the type A symbo...

Abstract

The embodiment of the invention provides a physical downlink shared channel (PDSCH) power setting method and device in SC-PTM. The method includes the following steps: determining first identificationinformation and second identification information of a PDSCH corresponding to a single-cell multimedia broadcast multicast service control channel (SC-MCCH); determining the transmitting power of a class A symbol and the transmitting power of a class B symbol on the PDSCH corresponding to the SC-MCCH; sending the PDSCH corresponding to the SC-MCCH to user equipment; determining the first identification information and the second identification information of the PDSCH corresponding to a single-cell multimedia broadcast multicast service traffic channel (SC-MTCH); determining the transmittingpower of the class A symbol and the transmitting power of the class B symbol on the PDSCH corresponding to the SC-MTCH; and sending the PDSCH corresponding to the SC-MTCH to the user equipment. According to the embodiment of the invention, the power setting of the PDSCH corresponding to the SC-MCCH and the SC-MTCH respectively can be implemented.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technologies, and in particular to a method and device for setting PDSCH power in SC-PTM. Background technique [0002] The 3rd Generation Partnership Project (3GPP) introduced the Single Cell Point To Multipoint (SC-PTM) feature, and SC-PTM added the single cell multimedia broadcast multicast service A Control Channel (Single-cell Multimedia Broadcast Multicast Service Control Channel, referred to as SC-MCCH) and a Single-cell Multimedia Broadcast Multicast Service Traffic Channel (Single-cell Multimedia Broadcast Multicast Service Traffic Channel, referred to as SC-MTCH). [0003] The SC-MCCH carries the SC-PTM configuration information of the cell. All user equipment (User Equipment, UE) receiving the Multimedia Broadcast Multicast Service (MBMS) in the cell need to receive the SC-MCCH. The coverage of the channel The range is the whole district. The Physical Downlink Sh...
