Problems solved by technology

Special burst can be found in "System for Improved Power Savings during Full DTX Mode of Operation in the Downlink" disclosed in International Patent Specification WO03034599 and "System and Method for Utilizing Unused Capacity in the Data field of a Special Burst" disclosed in International Patent Specification WO03032521 ", where the latter indicates that a special burst needs to be marked with a specific TFCI value, and this TFCI value cannot be used to identify other TFCs, thus making the size of TFCS 2 N In the case of , the system needs to use N+1-bit TFCI. After TFC is encoded, the physical channel will consume more resources for TFCI transmission, for example, an additional 16 bits are required; on the other hand, this may cause an empty TFC to have Two TFCI values ​​violate the requirement of uniqueness, or affect the integrity of TFCS; at the same time, the information of TFCS does not reflect the use of discontinuous transmission

Embodiment approach 1

[0016] Referring to Fig. 2, Embodiment 1 of the present invention can be briefly described as follows: when the network end receives the TFCS related to the user equipment and the link, it always places the empty TFC at the pre-agreed position of the system, and the communication parties will use the special burst The TFC is set using the agreed value indicated by the Transport Composition Format. For example: a TFCI value of 0 can be used to indicate a special burst, and the first TFC is designated as an empty TFC, then the communication parties set the transmission combination format indication value corresponding to the first TFC to 0. For the remaining TFCs, different TFCI values ​​can be set in sequence.

[0017] Before the implementation, the communication parties agree that the TFCI value used for the special burst is X, and the position of the empty TFC in the TFCS is Y. Then perform the following steps:

[0018] Step 11, the network side places the empty TFC at an a...

Embodiment approach 2

[0025]Referring to Fig. 3, Embodiment 2 of the present invention can be briefly described as: when the network end receives the TFCS related to the link of the user equipment, it does not intentionally place the empty TFC at a specific position, and the communication parties will search for the TFC in the TFCS. Null TFC and set this TFC with the agreed value indicated by the Transport Combination Format used by the particular burst. For example: TFCI value 0 can be used to indicate a special burst. If the communication party searches for an empty TFC in the second position, the communication parties will use 0 to indicate the second TFC. For the rest of the TFCs, the settings are different according to the order. The TFCI value is enough.

[0026] In this case, the communication parties have agreed in advance on the TFCI value X used by the special burst, but have not agreed on the position of the empty TFC in the TFCS. Therefore, as shown in Figure 3, compared with Embodimen...

Abstract

This invention discloses an empty transmission format combination process method in a time sharing duplex system, in which, a network end transfers the transmission format combined set to the base station and a user device in a certain way, the two part of communication make conventions about special burst used transmission format combined instruction value and judge if they apply the special burst based on that if the empty transmission format combination contains zero transmission block, if so, they apply the special burst and prepare to process data discontinuously, if not, the two parties will process the data based on normal data transmission.

Description

technical field [0001] The present invention relates to the technical field of Code Division Multiple Access (CDMA) mobile communication, in particular to the air transmission format of Time Division Code Division Multiple Access (TD-CDMA) mobile communication system and Time Division Synchronous Code Division Multiple Access (TD-SCDMA) mobile communication system Combined processing methods. Background technique [0002] For a communication system, it is key for both parties to use a consistent information format, and when it comes to multiple information formats to choose from, the sender needs to indicate the currently used information format to the other party in a certain way, and try its best to ensure the correctness of the instructions. Just as the IP packet header of the Internet protocol contains information for indicating the transmission protocol and the length of the data packet. This involves two aspects of information format and information format indication...
