Embodiment Construction

[0076] The following description of example embodiments refers to the accompanying drawings. In different drawings, the same reference numbers identify the same or similar elements. The following detailed description does not limit the invention. Instead, the scope of the invention is defined by the appended claims. For simplicity, the following embodiments are discussed with respect to the terminology and structure of the TD-SCDMA system described above. However, the embodiments to be discussed next are not limited to these systems, but can be applied to other existing telecommunication systems, such as WCDMA and the like. Furthermore, although the following description uses terms specific to the TD-SCDMA system, the terms base station, terminal equipment, wireless control network are used in a general sense. For example, the term "base station" may include a Radio Base Station (RBS), Node B, eNode B or other node. The term "terminal device" may include mobile phones, per...

Abstract

A base station, user terminal, computer readable medium and method for accepting an uplink channel, for a point-to-multipoint (P-t-M) multimedia broadcast and multicast service (MBMS) transmission mode, from multiple user terminals to a base station, the base station serving the multiple user terminals in a communication network. The method includes: setting up a downlink MBMS traffic channel (MTCH) from the base station to the multiple user terminals; transmitting first data from the base station via the MTCH channel in the P-t-M mode, wherein the P-t-M mode pushes data from the base station to the multiple user terminals; receiving from the multiple user terminals messages via an uplink MBMS Feedback Channel (MFCH), wherein the messages indicate whether the first data transmitted from the base station has been decoded successfully or not at the multiple user terminals; and deciding whether to transmit second data or retransmit the first data from the base station to the multiple user terminals based on the received messages.

Description

technical field [0001] The present invention relates generally to wireless communication systems, devices, software and methods, and more particularly to mechanisms and techniques for point-to-multipoint (P-t-M) Multimedia Broadcast Multicast Service (MBMS) uplink communications in telecommunication networks. Background technique [0002] Over the past few years, there has been a growing interest in providing voice, video and data services in wireless access technologies. There are various telecommunication technologies used in cellular communications. For mobile communications, the most widely used radio access technology is digital cellular. There is growing interest in 3G (Third Generation) systems. One such 3G system is based on Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), which may be a standard to be used in China. [0003] The International Telecommunication Union (ITU) has adopted TD-SCDMA as a Time Division Duplex (TDD) option for Internati...
