Problems solved by technology

[0009] Multiplexing methods on the physical channel include multi-frame allocation, code division multiplexing, and upper-layer transmission channel multiplexing. However, MBMS services cannot be realized by time-division multiplexing multi-frames on the SCCPCH channel. Sharing can only be defined as a way in which a physical channel continuously occupies certain channelization code resources of a certain time slot

Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030]In a TD-SCDMA system, a physical channel is defined as a physical resource on a specific system frame, a specific time slot, and a specific channelization code. Therefore, the same channelization code on the same time slot can implement different physical channels through time division multiplexing. For example, physical channel 1 is defined as time slot number 5 with an odd system frame number and occupies channelization code 1; physical channel 2 is defined as time slot number 5 with an even system frame number and occupies channelization code 1. In this way, physical channels 1 and 2 are defined on the same time slot number and channelization code through time division multiplexing.

[0031] In a typical MBMS service configuration requirement, when multiple MBMS services need to be carried on a certain frequency point and a ...

Abstract

A method of utilizing multi-frame to receive and transmit MBMS in TD-SCDMA includes sending multi-frame configuration information of physical channel carrying MBMS service to user device by radio network controller through MBMS point to multipoint control channel, sending out MBMS data by network side according to said multi-frame configuration information and receiving MBMS service data on follow-up secondary pubic control physical channel by user device according to physical channel multi-frame configuration information received from MBMS point to multipoint control channel.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for a Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system carrying Multimedia Broadcast Multicast Service (MBMS). Background technique [0002] With the popularization of large-screen multifunctional mobile phones, the application of mobile data services is becoming more and more extensive. emerge. Various high-bandwidth multimedia services, such as video conferencing, TV broadcasting, video-on-demand, advertisements, online education, and interactive games, continue to emerge. On the one hand, they meet the ever-increasing service demands of mobile users, and at the same time, they bring new services to mobile operators. growth point. These mobile multimedia services require multiple users to receive the same data at the same time. Compared with general data, they have the characteristics of large data volume, long duration, and delay sensit...
