Embodiment Construction

[0057] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and drawings.

[0058] In order to overcome the low utilization rate of the USF of the time slot PDCH allocated to the terminal without affecting the resource utilization rate of the communication system, the present invention can only set one for each PDCH allocated to the terminal. The USF that identifies the terminal corresponding to the PDCH, this USF is unique in each PDCH, and the USF set in different PDCHs for identifying the terminal corresponding to the PDCH may be the same or different. In this way, one PDCH can be allocated to 8 terminals at most, which improves the USF utilization rate in one PDCH.

Abstract

This invention discloses a packet data channel PDCH methods used by the direct send data terminals, in which at the end of each PDCH distributed in advance set a logo USF corresponding to the end of the uplink PDCH state logo. The method still includes: A1. According to the sequence of PDCH slot descending, the terminal eavesdrops PDCH distributed in advance of whether the current frame receives their corresponding USF, and if so, to implement steps B1; Otherwise, to end this process; B1.the slot through the terminal can not high than their counterparts in the host USF slot of the PDCH one or more slot of PDCH uplink in the current frame and send the data in the next block. This invention provides methods without affecting the communication system resource utilization circumstances, and can overcome the low utilization rate of the time slot allocated by the end of the USF PDCH.

Description

Technical field [0001] The present invention relates to a technology for allocating a packet data channel (PDCH) in a communication system, and more particularly to a method for indicating a PDCH used by a terminal to send data. Background technique [0002] At present, when a terminal in a communication system, such as a terminal in a general packet radio service (GPRS) system or a global system for mobile communication (GSM), wants to send data to the communication system network side, it first sends a data-carrying service to the communication system network side The uplink channel request for the allocation of characteristic parameters. The service characteristic parameters are the rate, delay, and error rate of the data to be sent; secondly, the communication system network side allocates PDCH to the terminal according to the data service characteristic parameters carried in the received request , Indicate the allocated PDCH to the terminal; finally, the terminal sends data ...
