Embodiment Construction

[0023] The embodiment of the present invention solves the problem of multiplexing multiple (for example, 2) users on a half-rate channel by designing a new 26-multiframe transmission scheme, which is equivalent to multiplexing 4 users on a full-rate channel. , In a 26-multiframe, the downlink SACCH frames of 4 users need to be used, which causes the problem that the SACCH frames are not enough.

[0024] see Figure 4 , which is a flowchart of a downlink multiframe transmission method according to an embodiment of the present invention, including:

[0025] S401: Set the positions of the SACCH frames and TCH frames of multiple users in the multiframe, and multiplex the SACCH frames of each user and the TCH frames of other users in the same time slot of the multiframe under the half-rate channel;

[0026] S402: Send the multiframe in a preset time slot.

[0027] It can be seen that by staggering the transmission of SACCH frames of users and users multiplexed with them, the norm...

Abstract

The invention discloses a method and a device for transmitting downlink multiframes. The method comprises the following steps: setting the positions of slow associated control channel (SACCH) frames and traffic channel (TCH) frames of a plurality of users in the multiframes, and multiplexing the SACCH frames of each user and the TCH frames of other users in a same time slot of the multiframes under a half-rate channel; and sending the multiframes at a preset time slot. Obviously, the method and the device reduce the influence on sounds as far as possible while ensuring the normal transmissionof the channel associated signaling of each user by adjusting the positions of the SACCH frames and the TCH frames of multiplexing users so that the SACCH frames of the users and the TCH frames of other users perform multiplex transmission, namely the SACCH frames of each user are transmitted in a staggered mode.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a downlink multiframe transmission method and device. Background technique [0002] With the continuous increase of the number of users, the pressure on the voice capacity in the mobile communication system is increasing day by day, and this situation is particularly obvious in regions or countries with a large population. At the same time, with the continuous development of technology, the competition has become increasingly fierce, and the charges for voice services have been continuously reduced. Operators are facing cost pressures and need to use hardware and spectrum resources more effectively. [0003] In traditional voice, one time slot is assigned to one user. If you want to increase the voice capacity, that is, carry more channels of voice on the same resource, you can use MUROS (Multi-User Reuse One Slot, multiple users reuse the same time slot) im...
