Problems solved by technology

However, since each SI occupies 18 bits, it will greatly increase the overhead
For example, assuming the MAC service data unit (SDU) size is 280 bits and the MAC-e header size is 18 bits, this represents approximately 6% overhead

Abstract

The invention provides a wireless transmit / receive unit (WTRU) and a method performed by the WTRU. The method comprises: triggering transmission of scheduling information (SI) by the WTRU when the current non-zero grant is smaller than a minimum required to transmit a next MAC service data unit (SDU) of the specific MAC-d flow; and transmitting the SI when the triggering condition is met.

Description

[0001] This application is a divisional application of a Chinese invention patent application filed on August 16, 2007 with the application number 200780031104.7 and the title of the invention "Method and device for preventing transmission blockage in HSUPA wireless communication system". technical field [0002] The present invention relates to a High Speed ​​Uplink Packet Access (HSUPA) wireless communication system. In particular, the present invention relates to a method and apparatus for preventing transmission blocking in an HSUPA wireless communication system. Background technique [0003] The 3rd Generation Partnership Project (3GPP) Release 6 defines fast control of Wireless Transmit / Receive Unit (WTRU) transmissions through Node B (NB) based scheduling in HSUPA. This faster control results in better control of uplink (UL) noise rise, which allows operation at higher average UL loads without exceeding thresholds, thereby increasing the capacity of the system. In HS...
