Embodiment Construction

[0043] At first, explain the basis of the present invention:

[0044] Based on single-carrier HSUPA, in a multi-carrier cell, the same as the HSUPA technology in a single-carrier cell, the uplink data service is sent through the E-DCH transmission channel; the MAC layer includes a MAC-e / MAC-es sublayer to complete related scheduling, priority Level processing, feedback, retransmission and other functions; the transmission channel E-DCH is mapped to the E-PUCH physical channel, the scheduling authorization information related to the E-PUCH physical channel is sent through the E-AGCH, and the E-HICH is used to feed back ACK / NACK information.

[0045] Secondly, the key of the present invention is illustrated: the single-carrier HSUPA scheduling transmission method and the non-scheduling transmission method are transformed, and the method of the present invention is specifically as follows:

[0046] (1) For scheduled transmission:

[0047] 1. E-PUCH, E-AGCH and E-HICH physical c...

Abstract

The invention relates to a high speed up link grouping access method of a multicarrier system, comprising: arranging E-AGCH, E-PUCH and E-HICH physical channel on one or a plurality of carriers; distributing useable E-AGCH, E-PUCH and E-HICH physical channel to for associate use on one or a plurality of carrier(s) through high level signaling; respectively building a MAC-e / MAC-es entity and a HARQ entity thereof and a course shared by each carrier at a network side and a terminal side, dynamically mapping the scheduling E-DCH transmitting data onto an E-PUCH physical channel of a carrier through the entity. The Node B dynamically schedules and authorizes the E-PUCH physical channel of the carrier to the terminal for E-DCH data transmission through E-AGCH carried with carrier indicating information. Receiving condition of E-DCH transmission on the carrier is fed back through the E-HICH physical channel.

Description

technical field [0001] The invention relates to mobile communication, in particular to a high-speed uplink packet access method for a multi-carrier system. Background technique [0002] (1) In order to meet the growing demand of users for high-speed uplink packet data services, and to better cooperate with the High Speed ​​Downlink Packet Access (HSDPA) technology to provide higher service quality Support, 3GPP introduced the high-speed uplink based on Wideband Code Division Multiple Access (referred to as WCDMA) system and Time Division Code Synchronization Division Multiple Access (referred to as TD-SCDMA) system in Rel6 and Rel7 respectively High Speed ​​Uplink Packet Access (HSUPA for short) technology, or Enhanced Uplink or Enhanced Dedicated Channel (E-DCH for short) technology. HSUPA adopts technologies such as hybrid automatic repeat request HARQ, high-order modulation (16QAM), node Node B fast scheduling, and T / P-based reverse RoT control, which can obtain higher u...
