A system for receiving and sending the MBMS in TD-SCDMA through a single time slot network

A TD-SCDMA, single-slot technology, applied in the field of wireless communication, can solve problems such as the inability to transmit and receive UTN MBMS data, affect the combined reception of multi-slot MBMS signals, and have no defined configuration, so as to avoid co-frequency interference of adjacent cells and improve The effect of spectrum utilization, good attenuation and homogenization

Problems solved by technology

As shown in Figure 1, for UTN MBMS signals transmitted using multi-slots with the same scrambling code, when the UE needs to combine signals with a long delay (for example, the delay with the MBMS signal of the local cell is greater than 16 chips) from the remote base station, Large delay signals with the same scrambling code will generate large cross-slot interference, which will affect the combined reception of multi-slot MBMS signals by UEs in UTN mode
[0011] In the existing 3GPP protocol, there is no definition of how to configure the UTN scrambling code information on a specific frequency time slot required by UTN in the TD-SCDMA system, so that MBMS data transmission and reception in UTN mode cannot be performed

Embodiment Construction

[0029] In this embodiment, a system for transmitting and receiving multimedia broadcast multicast services using a single-slot network includes a radio network controller, a node B, and a user equipment, wherein:

[0030] The radio network controller is configured to send UTN configuration information to the user equipment, configure a UTN scrambling code for each time slot carrying MBMS services, and establish a secondary public control physical channel carrying MBMS services with Node B, And configure the UTN scrambling code for Node B, and the secondary public control physical channel is hereinafter referred to as SCCPCH;

[0031] The node B is configured to establish an SCCPCH channel with a radio network controller, and send MBMS data after scrambling using the configured UTN scrambling code;

[0032] The user equipment is configured to receive MBMS service data on the subsequent SCCPCH according to the received UTN configuration information.

[0033] When the MBMS servi...

Abstract

The disclosed MBMS system with UTN in TD-SCDMA comprises: a wireless network controller, which sends UTN configuration message to UE to configure a UTN code for every time slot and the SCCPCH for node, and configures UTN code for node; a node B building SCCPCH channel with last controller and interfering the MBMS data to transmit; and UE receiving MBMS data according to the received UTN message. This invention avoids same frequency interference of near subzones.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a transceiver system for multimedia broadcast and multicast services in a Time Division Synchronous Code Division Multiple Access System (TD-SCDMA). Background technique [0002] With the rapid development of the Internet and the popularization of large-screen multifunctional mobile phones, a large number of mobile data multimedia services have emerged, and various high-bandwidth multimedia services have emerged, such as video conferencing, TV broadcasting, video on demand, advertising, online education, interactive games, etc. On the one hand, it meets the ever-increasing business demands of mobile users, and at the same time brings new business growth points for mobile operators. 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, an...
