Problems solved by technology

[0004] The above-mentioned CMMB system is used as a standard and widely used because of its large bandwidth (the bandwidth of 2M or 8M can be realized), but the current CMMB can only be used for the downlink transmission of multimedia data, which makes the advantage of its large bandwidth impossible. fully applied

Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] The method provided by the present invention mainly includes: configuring the resources where N time slots are located in the CMMB wireless frame except the first time slot TS0 as uplink transmission resources, configuring the resources where other time slots are located as downlink transmission resources, and configuring The resource configuration information is sent to the terminal through the first time slot TS0 of the radio frame; wherein, N is an integer and 1≤N≤39.

[0023] Correspondingly, the terminal will obtain the resource configuration information through the first time slot TS0 of the CMMB radio frame, and according to the resource configuration information, in the CMMB radio frame except the first time slot TS0, the resources w...

Abstract

The invention provides a method, a base station and a terminal for realizing the bidirectional data transmission based on CMMB (China Mobile Multimedia Broadcasting). The method comprises the following steps of: configuring resources of N time slots but the first time slot TS0 in the CMMB wireless frame as uplink transmission resources, configuring resources of other time slots as downlink transmission resources, and sending the resource configuration information to the terminal via the first time slot TS0 of the wireless frame. The invention not only can realize that the base station broadcasts multimedia data to each terminal, but also can realize that each terminal sends the multimedia data to the base station, that is the bidirectional transmission of the multimedia data based on CMMB, thereby making fuller use of the advantages of CMMB.

Description

technical field [0001] The invention relates to multimedia mobile communication technology, in particular to a method, base station and terminal for realizing two-way data transmission based on China Mobile Multimedia Broadcasting (CMMB). Background technique [0002] The mobile multimedia broadcasting service refers to a service in which a mobile terminal sends multimedia data such as digital audio and video in the form of broadcasting. As a new multimedia service, it has attracted widespread attention in the industry. [0003] In the existing China Mobile Multimedia Broadcasting (CMMB) system, the broadcast channel physical layer provides a broadcast channel for upper layer services through a physical layer logical channel (PLCH). The PLCH is divided into a control logic channel (CLCH) and a service logic channel (SLCH). The CLCH is used to carry broadcast system control information, and the SLCH is used to carry broadcast service data. figure 1 It is the physical frame s...
