Problems solved by technology

Since the packet domain services transmitted in the original MAC layer are non-delay-sensitive services, and are transmitted on the high-speed downlink shared channel and the enhanced uplink dedicated channel, and the VoIP service is a delay-sensitive service, the MAC layer follows the above process Processing the business will cause a high delay of the VoIP business, which affects the service quality of the VoIP business

Embodiment Construction

[0118] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0119] The main idea of ​​the present invention is that in the downlink direction, all dedicated logical channels are mapped to downlink shared channels; in the uplink direction, all dedicated logical channels mapped to non-random access channels are mapped to uplink shared channels. Therefore, the dedicated transmission channel can be removed, and the service processing flow in the MAC layer can be simplified. The present invention can be applied in LTE technology.

[0120] The following describes the service processing method on the downlink channel in the MAC layer and the service processing method on the uplink channel in the MAC layer respectively.

[0121] In the downlink direction, the MAC layer on the UTRAN side processes the service data from the dedicat...

Abstract

The invention discloses a downlink channel service processing method in MAC layer, comprising: UTRAN-side MAC layer processes the received service data from special logic channel and sends the processed service data to downlink shared channel; correspondingly, UE-side MAC layer processes service data comining from the downlink shared channel and sends the processed service data to a corresponding special logic channel. And the invention also discloses an uplink channel service processing in MAC layer, comprising: UE-side MAC layer processes the received service data mapped into special logic channel of nonrandom access channel and sends the processed service data to uplink shared channel; correspondingly, UTRAN-side MAC layer processes service data coming from the uplink shared channel and sends the processed data to the special logic channel.

Description

technical field [0001] The invention relates to the technical field of wireless communication system service transmission, in particular to a service processing method on a downlink channel in a medium access control (MAC) layer, and a service processing method on an uplink channel in a MAC layer. Background technique [0002] The Universal System for Mobile Communications (UTMS) uses Wideband Code Division Multiple Access (WCDMA) wireless transmission technology on the air interface, as shown in Figure 1, the wireless interface protocol standard in the R6 version of the 3GPP protocol, as can be seen from Figure 1 , the UTMS air interface is divided into three protocol layers: L1, L2 and L3, which correspond to the physical layer, data link layer and network layer of the OSI reference model respectively, and the L2 layer is divided into MAC layer, radio link control (RLC layer). ) layer, packet data concentration protocol (PDCP) layer and broadcast / multicast control (BMC) la...
