Reporting method of the scheduling information in the high-speed uplink packet access

Abstract

The invention relates to mobile communication technique, disclosing a method for reporting scheduling information (SI) in high speed uplink packet access (HSUPA), raising wireless resources utilization ratio as reporting SI. In the invention, if the current periodical SI reporting needs to consume extra wireless resources and there has been or is possibly SI reporting caused by other reasons in the time period about the triggering time of the periodical SI reporting, neglecting the current periodical SI reporting. And it has three concrete modes of: 1. monitoring a preset time period before the periodical triggering time: if there has been SI reporting, able to neglect the current periodical reporting; 2. neglecting the current periodical reporting and monitoring the SI reporting condition in the following preset time period: if no SI reporting, then making a supplementary reporting; and 3. whenever reporting SI, delaying each following periodical reporting.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to high-speed uplink packet access technology. Background technique [0002] The 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as "3GPP"), as an important organization in the field of mobile communications, has promoted the standardization of the 3rd Generation Mobile Communications (The Third Generation, referred to as "3G") technology. Its early protocol Both uplink and downlink services in this version are carried on dedicated channels. [0003] With the development of mobile communication technology, 3G technology is also constantly evolving. High Speed ​​Downlink Packet Access (HSDPA for short) and High Speed ​​Uplink Packet Access (HSUPA for short) are important evolutions of 3G technology. Scheduling and retransmission of data packets in HSDPA and HSUPA are controlled by a base station node (Node B). [0004] Among them, HSDPA was int...

Problems solved by technology

[0018] In practical applications, the above scheme has the following problems: the utilization rate of wireless resources when reporting SI is low

[0019] The main reason for this situation is that once the SI report is triggered, the SI report must be transmitted separately or multiplexed with the data on the MAC-e PDU to transmit the SI report, which will inevitably occupy a certain amount of uplink wireless resources

[0020] In addition, when the SI report and the data to be transmitted are multiplexed on the MAC-e PDU and sent together, if the D of the MAC-e PDU is less than the 18 bits required for multiplexing the SI, it will result in a larger E-DCH transmission blocks, and then fill the resulting remaining bits, thus wasting more wireless resources
