Problems solved by technology

In this way, those terminals with a larger power headroom are forced to use a lower rate to transmit data, and make the gains brought by the fast scheduling of short transmission time intervals unavailable; at the same time, those terminals with a smaller power headroom terminal, and cannot benefit from the larger cell edge coverage brought by the scheduling period of the long transmission time interval

Embodiment Construction

[0065] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0066] The present invention aims to make the public E-DCH resources in the cell not only be used for short transmission time interval scheduling, but also for long transmission time interval scheduling; according to the network coverage and terminal characteristics, the terminal dynamically selects the short transmission time Use E-DCH resources at regular intervals or long transmission time intervals to ensure coverage and meet high-speed user rates.

[0067] For this reason, in a method for processing enhanced dedicated transmission channels provided by the present invention, the terminal selects a short transmission time interval or a long transmission time interval to use E-DCH resources according to the measurement results of the cell where it resides, and by giving The preamble of the PRACH carrying the E-DCH ...

Abstract

The invention discloses a method for processing an enhanced dedicated transport channel (E-DCH) and a system thereof. The method comprises the following steps that: a terminal selects a short transmission time interval or a long transmission time interval to use an E-DCH resource according to a measurement result of a resident cell; the terminal notifies a node B of transmission time interval information selected by the terminal through scrambling different scrambling codes for a leading part of a physical random access channel (PRACH) which carries the E-DCH. By using the method and the system of the invention, the common E-DCH resource in the cell can be used for scheduling of the short transmission time interval and also can be used for the scheduling of the long transmission time interval. Coverage can be ensured and a high speed of a user can be satisfied.

Description

technical field [0001] The present invention relates to High Speed ​​Uplink Packet Access (HSUPA, High Speed ​​Uplink Packet Access) technology, in particular to a method and system for processing enhanced dedicated transmission channels. Background technique [0002] High Speed ​​Uplink Packet Access (HSUPA, High Speed ​​Uplink Packet Access) technology improves the performance of uplink packet data through technical means such as fast scheduling and fast retransmission combining at the physical layer. The HSUPA technology introduces a new transport channel, that is, Enhanced Dedicated Transport Channel (E-DCH, Enhanced Dedicated Transport Channel), which is used to carry user data and has a single uplink direction. The physical channel carrying the E-DCH is a Physical Random Access Channel (PRACH, Physical Random Access Channel). [0003] The two basic modes of operation of a terminal are idle mode and connected mode. Among them, the connection mode can be further divide...
