[0003] The TTI of 2ms can provide a higher uplink data rate, but there is a prerequisite for this, that is, the quality of the signal must meet certain requirements
[0005] However, in the prior art, it is not possible to dynamically switch the TTI working mode, even if it can be switched, it is only manually switched according to the throughput

Abstract

The invention provides a high-speed wireless uplink resource scheduling method, which is used for dynamically adjusting a transmission time interval mode of high-speed uplink packet access according to path loss; wherein, the transmission time interval mode comprises a 2ms mode and a 10ms mode. The high-speed wireless uplink resource scheduling method comprises the following steps: 1E / 1F measuring objects of user equipments are configured as receiving signal code power, and 1E threshold and 1F threshold are configured; the transmission time interval mode is adjusted according to reported events of the user equipments; wherein, the reported events of the user equipments comprise a 1E event and a 1F event. The high-speed wireless uplink resource scheduling method can switch the HSUPA TTI mode according to the 1E and 1F events reported by the user equipments and lead the TTI mode of HSUPA to be dynamically adjusted between 2ms and 10ms according to path loss.

Description

technical field [0001] The present invention relates to a communication system, in particular to a high-speed wireless uplink resource scheduling method. Background technique [0002] 3GPP introduced the concept of High-Speed ​​Uplink Packet Access (HSUPA) in the R6 version, which is different from the High-Speed ​​Downlink Packet Access (HSDPA) technology. In HSUPA, The high-speed wireless uplink (Enhanced uplink Dedicated Channel, EDCH for short) has two transmission time interval (Transmission Time Interval, TTI for short) working modes, namely 2ms working mode and 10ms working mode. The difference between these two working modes is mainly reflected in the coverage capability of the cell, such as figure 1 shown. [0003] The TTI of 2ms can provide a higher uplink data rate, but there is a prerequisite for this, that is, the quality of the signal must meet certain requirements. This is because, if it is at the edge of the cell, the TTI of 2ms will require higher transmi...
