Problems solved by technology

When the UE is not authorized, it will send scheduling information through the E-RUCCH channel, such as Figure 2a As shown, the situation where the UE is not authorized includes that the UE's E-DCH bearer is initially established, and the UE has data to transmit; or the UE has not continued to obtain authorization for a period of time after the latest authorization is used up.

Abstract

The invention provides a method for reporting dispatching information of a multi-carrier enhanced uplink access system, which includes the following steps: dividing dispatching information into long dispatching information and short dispatching information, judging the length after the length of a data cell transport block of an enforced medium access control protocol minus the length of a data part and the length of a packet header part and then determining to add the long dispatching information or the short information to the data cell of the enforced medium access control protocol according to the result of judging, wherein, the long dispatching information comprises common information and special information of carrier and the short dispatching information comprises only the special information of carriers. Therefore, the method of the invention is applicable to the condition that UE is authorized and ensures that the report of the dispatching information reduces system overhead as far as possible and has certain timeliness.

Description

technical field [0001] The present invention relates to the field of wireless communication, and more specifically relates to a method for reporting scheduling information of a multi-carrier enhanced uplink access system. Background technique [0002] The enhanced uplink access system is generally called HSUPA (High Speed ​​Uplink Packet Access, High Speed ​​Uplink Packet Access), which aims to improve the efficiency of the uplink through advanced technology to effectively support web browsing, video, multimedia information and other information based on IP business. [0003] Currently, 3GPP (Third Generation Partnership Project Organization) has completed the standardization work of TD-SCDMA enhanced uplink access system. Applicable to single carrier TD-SCDMA system. A new transmission channel E-DCH (enhanced uplink dedicated transmission channel) is added to the enhanced uplink access system, and the TTI (transmission time interval) of the E-DCH is 5ms. The packet mappe...
