Problems solved by technology

However, in HSUPA cells, the number of E-AGCHs is limited (E-AGCHs will occupy downlink codeword resources), and E-AGCHs are common channels shared by multiple UEs in time division, especially for 10msTTI UEs. Sending an AG command takes 10 ms of sending time, so the E-AGCH channel cannot be frequently occupied, and it cannot be guaranteed that these UEs can obtain the sending opportunity of AG in time, therefore, the UE will not be able to send the scheduled command for a long time data, thus affecting scheduling performance

Embodiment Construction

[0025] The first embodiment of the present invention provides a method for scheduling data transmission according to authorization. In this embodiment, when the UE does not receive the AG command, and the value of the current HARQ process is activated, the main authorization value is true, and the service authorization value is not. equal to 0, and when the AG timer expires, if the UE receives the RG command containing UP information sent by the base station node, it will judge whether the current SG value is the minimum service authorization value specified in the current agreement. If the current SG value is The minimum service authorization value means that the previous RTT of the current HARQ process does not have scheduled data transmission, so according to the size of the RLC PDU of the currently scheduled data to be sent, determine the Index (index value), and send scheduling data based on it. The specific implementation process is as figure 1 shown, including:

Abstract

The invention discloses a terminal apparatus and a method of transmitting scheduling data according to licensing; when receiving the relative licensing command, the SG value capable of satisfying the service licensing of the scheduling data block to be sent is ensured according to the size of the scheduling data block to be sent. So, under the condition that the front RTT in the same HARQ process does not transmit the scheduling data, UE is able to instantly send the scheduling data block according to the ensured SG value, thereby reducing the consumption of E-AGCH, improving the scheduling efficiency and improving the scheduling performance.

Description

technical field [0001] The invention relates to the communication field, in particular to the grant scheduling technology. Background technique [0002] With the development of mobile communication technology, the third generation mobile communication (The Third Generation, "3G" for short) technology is also constantly evolving. For example, High Speed ​​Downlink Packet Access (HSDPA for short) and High Speed ​​Uplink Packet Access (HSUPA for short) are important evolutions of 3G technologies. [0003] Currently, the scheduling and retransmission of data packets in HSDPA and HSUPA are controlled by the base station node (Node B): [0004] The base station node usually sends a relative grant (RG) command to a user terminal (User Equipment, UE) through a relative grant channel (E-DCH Relative Grand Channel, referred to as "E-RGCH"); the RG command includes UP, HOLD or DOWN information, wherein the UP represents increasing the step value on the basis of the current authorized...
