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

Embodiment Construction

[0046] 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 the accompanying drawings.

[0047] The present invention determines whether to send the SI report this time according to the real-time nature of the SI report and the size of D of the MAC-e PDU currently available for multiplexing with the SI when the existing trigger condition of the SI report is satisfied.

[0048] Specifically, the trigger conditions of the SI report are mainly divided into two categories: period trigger and event trigger. Among them, event-triggered real-time requirements are relatively high, that is, once an event triggers an SI report, the UE should transmit the SI report as soon as possible without delay; while the periodic-triggered SI report has relatively low real-time requirements, especially when When the cycle time is longer.

[0049] Wherein, in the trigger...

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 present invention relates to mobile communication technology, in particular to high-speed uplink packet access technology. Background technique [0002] The 3rd Generation Partnership Project ("3GPP"), as an important organization in the field of mobile communication, has promoted the standardization of the third generation mobile communication ("The Third Generation", "3G") technology. The bearer of uplink and downlink services in the version is based 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. The scheduling and retransmission of data packets in HSDPA and HSUPA are controlled by a base station node (Node B). [0004] Among them, HSDPA was introduced into the 3GPP Release 5 (Release 5, referred to as "R5...
