Method, system and device for transmitting downlink associated control channel frames

Abstract

The embodiment of the invention provides a method, a system and a device for transmitting downlink associated control channel frames. The method comprises the following steps: multiplexing slow associated control channel frames of a plurality of users in a same time slot of multiframes of a half-rate channel; forming slow associated control channel blocks by each four slow associated control channel frames, wherein the slow associated control channel block formed by the slow associated control channel frames of at least one of the plurality of users comprises common information and specific information of the user, and the slow associated control channel blocks formed by the slow associated control channel frames of the rest users of the plurality of users comprise the specific informationof the users; and sending the multiplexing slow associated control channel frames. When a plurality of users multiplex the same time slot, the correct transmission of the slow associated control channel frames of each user can be ensured.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a transmission method, system and equipment of a downlink associated control channel frame. Background technique [0002] The traditional voice is allocated to one user in one time slot. In order to increase the voice capacity, it is necessary to carry more channels of voice on the same resource. ) to multiplex multiple users, so that a significant increase in capacity can be obtained on a fixed carrier frequency and spectrum. [0003] To this end, the Multi-User Reuse One Slot (MUROS, Multi-User Reuse One Slot) technology is introduced. MUROS technology can provide two sub-channels so that two mobile stations (MS, Mobile Station) can work on the same wireless resource . Each MS occupies a sub-channel, and the sub-channels are distinguished by orthogonal or nearly orthogonal training sequences. For traditional circuit switched (CS, Circuit Switched) voice services, ea...

Problems solved by technology

When the transmission channel is a half-rate channel, one user uses 12 frames to transmit channel-associated signaling, and the other user uses 25 frames that were originally IDLE frames to transmit channel-associated signaling, which can ensure correct transmission of two users , however, after performing MUROS multiplexing at half rate, the existing method cannot satisfy four users to multiplex the same time slot at the same time, that is to say, the voice parts of four users can be multiplexed in 24 multiframes, The channel-associated signaling of 4 users cannot be multiplexed in 12 frames and 25 frames (that is, two SACCH frames), that is, only the channel-associated signaling of two users can be transmitted

[0005] In the process of realizing the present invention, the inventor found that although MUROS was introduced in the prior art, when multiplexing 2 users on a half-rate channel, it is equivalent to multiplexing four users on a full-rate channel , the positions of the two downlink SACCH frames cannot transmit the channel-associated signaling of the four users, that is, the positions of the two SACCH frames cannot correctly transmit the SACCH frames of the four users
