Problems solved by technology

[0013] Since the MS adopts the data service reception method of periodically listening to multiple carrier frames and dedicated carrier frames, the corresponding receiving operation method cannot meet the receiving requirements for irregular data transmission services; for example, a user simultaneously Perform unicast services and irregular multicast services, and the two services are transmitted through multiplexed carriers and dedicated carriers respectively. At this time, even if the data traffic of the multicast service is small, the MS still needs frequent interception and multiplexing On the contrary, even if the data traffic of the multicast service is large, the MS still needs to frequently listen to the dedicated carrier, making the corresponding listening process complicated and unable to meet the needs of service reception.

Embodiment 1

[0073] In the first embodiment, the MS first switches from the multiplexed carrier to the MBS dedicated carrier, and then continues to receive service data on the dedicated carrier.

[0074] In the first embodiment, the specific transmission frame format is as Figure 4 As shown, the corresponding processing flow includes:

[0075] (1) In the first frame, the MS first receives the signal from the multiplexed carrier, and the first frame contains the registered MBS service data domain identifier;

[0076] Specifically, the MS may determine that the DL-MAP of the first frame contains E-MBS IE information, and the corresponding E-MBS IE information includes the registered MBS service data field identifier;

[0077] (2) switching to a dedicated carrier for receiving MBS service data in the second frame, and still including the registered MBS service data domain identifier in the second frame;

[0078] Since the E-MBS IE information in the first frame contains the registered MBS ...

Embodiment 2

[0082] In the second embodiment, the MS first switches from receiving service data on the multiplexed carrier to receiving service data on the dedicated carrier, and then switches from receiving service data on the dedicated carrier back to receiving service data on the multiplexed carrier. Receive business data.

[0083] In the second embodiment, the specific transmission frame format is as Figure 5 As shown, the corresponding processing flow includes:

[0084] (1) In the first frame of the multiplexed carrier, the MS determines that the DL-MAP contains E-MBS IE information, and the E-MBS IE information contains the registered MBS service data domain identifier;

[0085] (2) The MS detects the E-MBS IE information and determines that it contains the registered MBS service data field identifier, that is, it determines that there is a registered MBS service that needs to be transmitted in the next dedicated carrier frame, so the MS will switch to Receive corresponding MBS se...

Embodiment 3

[0092] The previous embodiment described the implementation of switching between a single dedicated carrier and a multiplexed carrier for service data transmission. In this third embodiment, it is provided to switch between multiple dedicated carriers and multiplexed carriers for load transmission. The implementation scheme of different service data, under this scheme, the format of the corresponding bearer carrier switching indication information is shown in Table 2:

Abstract

The present invention provides a transmission method and device in switching process of carrier wave, wherein the method comprises the following procedures: transmitting service with multiplexing carrier or special carrier, and carrying carrier switching indicating information which is used for representing that the next frame is multiplexing carrier frame or special carrier frame in the transmitted multiplexing carrier or special carrier frame; and receiving the service carried in the next frame of multiplexing carrier or special carrier according to the carrier switching indicating information for processing. As a service transmission mode that carrier switching indication information is transmitted in multiplexing carrier frame or special carrier frame in an embodiment of the invention, the carrier type of the next frame can be obtained at the service receiving end, thereby facilitating the receiving and processing of service with a corresponding carrier signal detecting and receiving mode, and furthermore increasing the efficiency for receiving the service. The requirement of service transmission can be satisfied with a lower realizing complexity.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a service transmission technology in the carrier switching process. Background technique [0002] With the rapid development of broadband wireless communication technology, the wireless communication network will be used to transmit more types of services, for example, the industry through the wireless communication network based on OFDMA (orthogonal frequency division multiple access) technology Perform MBS (multicast broadcast service, multicast and broadcast services) transmission. [0003] In a wireless communication network based on OFDMA technology, data is transmitted in units of frames, and the time and frequency resources in each frame are allocated to different users for data transmission, so as to realize simultaneous communication of multiple users. Taking the TDD (Time Division Duplex) transmission environment as an example, each frame will be...
