Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0027] In this embodiment, the current CHPA cell defines only one uplink shared channel USCH. Currently there are two mobile stations that need to upload data, UE1 has 10 data packets, and UE2 has 4 data packets. Assuming that the current time is SFN=4090 (the range of SFN is 0..4095, and the modulo 4096 will be taken again after exceeding), so both UE1 and UE2 start to send uplink data after SFN=0.

[0028] First, UE1 and UE2 respectively request WIB to allocate channel resources to them through uplink RACH.

[0029] WIB performs scheduling according to the current resource status, UE priority, and measurement values ​​of each UE, and sends USCH configuration parameters to UE1 and UE2 respectively from DSCH or FACH (Forward Access Channel). See the table below for the parameters.

Abstract

The invention discloses a process for initializing uplink shared communication channel in the communication system. In the time division duplex TDD communication system of the asymmetric grouping service, the uplink and downlink resources usually use asymmetric design in which more resources are allocated to downlinks, and uplink resources are in short supply. The process provided in the invention makes full use of the limited uplink resources by setting uplink shared channel in the communication system, thus providing uplink data, physical layer signaling and high layer signaling service for a plurality of mobile terminal UEs having relative small uplink traffic volume.

Description

technical field [0001] The invention relates to the 3G enhancement technology of the third generation mobile communication system and the cellular high-speed packet access technology. Especially for TDD systems of asymmetric packet services. Background technique [0002] In a TDD communication system serving asymmetric data services, generally speaking, in order to better provide downlink high-speed services, more downlink time resources are allocated and less resources are used for uplink transmission. However, within the allocated less uplink transmission time period, it is necessary to provide uplink user data, high-layer signaling and physical layer signaling of all user equipment UEs in the cell. For services such as WWW browsing and FTP, UE does not need to send uplink data most of the time. Even if uplink data is sent, the amount of data sent is very small. For example, in the technical specification of 3GPP, TS 25.331 RRC Protocol (...
