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. Configure E-PUCH, E-AGCH and E-HICH ...

Abstract

The invention relates to a high speed uplink packet access (HSUPA) method for a multicarrier system, which comprises allocating E-AGCH, E-PUCH and E-HICH physical channels on one or more carrier waves at the same time; allocating one or more E-PUCH physical channel carrier wave resources for a terminal, and allocating one or more E-AGCH and E-HICH physical channels on one or more carrier waves and correlating with the E-PUCH physical channel on the same carrier wave; constructing one MAC-e / MAC-es entity on the network side and on the terminal side respectively, wherein the entities share carrier waves but independently allocate a HARQ process; and dynamically mapping scheduled E-DCH transmitted data on one or more carrier waves; a Node B authorizes the correlated E-PUCH physical channels on one ore more carrier waves to the terminal via one or more E-AGCH dynamic scheduling authorizations for E-DCH data transmission; the Node B feeds back the reception state of the E-DCH transmitted data via one E-HICH physical channel on each carrier wave.

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...
