Problems solved by technology

In the existing algorithm, when the first data volume is smaller than the second data volume, the power grant is not enough to enable the UE to send all the first data volume values ​​at one time, and it needs to be scheduled multiple times to enable the UE to send all the first data volume values , resulting in the problem of low scheduling efficiency

Embodiment 1

[0026] In view of the problems existing in the prior art, Embodiment 1 of the present invention provides a method for determining power authorization, which can be applied to at least TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) system , and used to improve the transmission efficiency and scheduling efficiency of HSUPA (High Speed ​​Uplink Packet Access) services, such as image 3 As shown, the method for determining the power authorization includes the following steps:

[0027] Step 301 , the base station device obtains the first amount of data currently to be sent by the UE (which may be called Buffer), and obtains the second amount of data that the UE can send within this TTI (which may be called bo).

[0028] In the embodiment of the present invention, the base station device obtains the first amount of data currently to be sent by the UE, including but not limited to the following methods: the base station device obtains the SI (Scheduling Informatio...

Embodiment 2

[0054] Based on the same inventive concept as the above method, an embodiment of the present invention also provides a base station device, such as Figure 4 As shown, the base station equipment specifically includes:

[0055] An obtaining module 11, configured to obtain a first amount of data currently to be sent by the user equipment UE, and obtain a second amount of data that the UE can send within this transmission time interval TTI;

[0056] The first determining module 12 is configured to use the first data amount to determine the number of the first medium access control protocol data unit MAC-d PDU, and use the second data amount to determine the second MAC-d PDU number;

[0057] The second determination module 13 is used to determine the corrected transport block size by using the second MAC-d PDU number when the second MAC-d PDU number is less than the first MAC-d PDU number a TBS value, and using the corrected TBS value to determine a power grant corresponding to the...

Abstract

The invention discloses a method and a device for determining power authorization. The method includes the steps: acquiring a first data volume to be currently transmitted of UE (user equipment) by base station equipment, and acquiring a second data volume capable of being transmitted by the UE within a TTI (transmission time interval); determining the number of first MAC-d PDUs (protocol data units) by the base station equipment according to the first data volume, and determining the number of second MAC-d PDUs by the base station equipment according to the second data volume; determining a modified TBS value of a transport block size by the base station equipment according to the number of the second MAC-d PDUs and determining the power authorization corresponding to the UE by the base station equipment according to the modified TBS value when the number of the second MAC-d PDUs is smaller than that of the first MAC-d PDUs; determining the modified TBS value by the base station equipment according to the number of the first MAC-d PDUs and determining the power authorization corresponding to the UE by the base station equipment according to the modified TBS value when the number of the second MAC-d PDUs is larger than or equal to that of the first MAC-d PDUs. By the aid of the method and the device, dispatching efficiency and transport efficiency can be improved, resource utilization rate is increased, and the throughput capacity of a cell is improved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method and device for determining power authorization. Background technique [0002] In the prior art, in order to determine the power authorization corresponding to the UE (User Equipment, user equipment), it is necessary to determine the first amount of data currently to be sent by the UE and the amount of data that the UE can send within this TTI (Transmission Time Interval, transmission time interval). After the second data amount, the first data amount is compared with the second data amount, and the power grant corresponding to the UE is determined based on the comparison result. [0003] Specifically, if the first data amount is greater than the second data amount, the corresponding power grant PRRI of the UE is: Among them, P thd is the actual signal-to-noise ratio of the UE, SF is the spreading factor, and CIR th2 The signal-to-noise ratio correspond...
