Problems solved by technology

Here we only list a possible corresponding relationship (as shown in Figure 5) to illustrate the existing problems: the TBS table that can be used by the UE (see Table 2, Table 2 is just a similar table in the 3GPP TS 25.321 agreement One, which has representative explanatory significance), the UE sends the smallest TB=18 and the corresponding authorized SG is SG-LUPR=0, the UE sends the second smallest TB=186 and the corresponding authorized SG is SG-LUPR=4, only one RG command is passed It is impossible for the UE to obtain a higher transmission authorization
However, since the SG required by the UE to send TB=186 is within the range specified by the 3GPP protocol (1 to 3 steps), it is impossible to increase the SG of the UE to the authorization corresponding to the ability to send TB=186 data packets through the RG command

Embodiment Construction

[0031] In order to facilitate a deep understanding of the technical content of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] The present invention uses the E-DPCH Information (E-DPCH information, Enhanced Dedicated Physical Channel Information) in the Node B Application Part (NBAP: Node B Application Part) protocol, and the E-DPDCH Info (Enhanced Dedicated Physical Channel Information) in the RRC (Radio Resource Control) protocol. A new Mininum-Grant-Index-Step-Size information element (IE, Information Element, such as Table 3), to configure the appropriate SG boost step size for the UE, so that when the UE uses the smallest SG and receives the RG, it can still effectively schedule the UE by sending the RG command, and quickly improve the UE scheduling Authorization, thus improving the efficiency of HSUPA packet scheduling. What I want to explain here is that the ...

Abstract

A method for dispatching uplink packet of radio communication includes using Minimum-Grant-Index-Step-Size information on NBAP protocol and RRC protocol to configure UE using minimum SG when dispatch authorization is required by UE and sending RG command to carry out dispatch on UE when RG is received by UE.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for improving wireless communication uplink packet scheduling. Background technique [0002] The WCDMA (Wideband Code Division Multiple Access) system is a broadband cellular wireless communication system based on CDMA. The WCDMA system supports more types of services and higher data rate service transmission capabilities. HSUPA (High Speed ​​Uplink Packet Access) is a WCDMA system enhancement technology for uplink transmission capability. HSUPA technology includes shorter TTI (Transmission Time Interval), Node B-based scheduler and HARQ (Hybrid Automatic Retransmission reQuest), the new transmission channel E-DCH (Enhanced Dedicate Channel) adopts these key technologies, and the HSUPA system can perform better than traditional The WCDMA version of WCDMA has significantly improved the transmission performance of uplink services, about 50%-70% increase in system capacity, 20%-5...
