Embodiment Construction

[0034] In order to solve the problem that the update of the UE buffered data volume maintained by the base station side is not timely, the technical solution provided by the embodiment of the present invention, before the base station receives the uplink data sent by the terminal, the buffered data volume of the terminal is calculated according to the scheduled data volume allocated to the terminal update, and after receiving the uplink data from the terminal, update the buffered data amount of the terminal again according to the demodulation result, so as to ensure that the buffered data amount of the terminal is updated in time. Especially when there is no data in the cache on the terminal side, the base station can know in time according to the amount of cached data maintained on the terminal side, avoiding continuous scheduling, improving the utilization of spectrum resources and network throughput, and avoiding waste of air interface resources .

Abstract

The invention discloses a method for updating cached data size of a terminal by a base station during uplink scheduling, and the base station. The method comprises the steps that: the base station updates cached data size of the terminal according to a value which is obtained by subtracting scheduling data size distributed for the terminal from the cached data size of the terminal; and the base station receives uplink data sent by the terminal, and updates cached data size of the terminal again according to a result of demodulation. According to the technical scheme provided by an embodiment of the invention, timely update for cached data size of the terminal is guaranteed, particularly when no data is cached on the terminal side, the base station side can know the situation according to cached data size on a maintained terminal side, and therefore, scheduling of the terminal with no data is avoided, utilization rate of spectrum resources and throughput capacity of network are enhanced, and waste of high frequency resources is prevented.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method and a device for a base station to update a buffered data amount of a terminal during uplink scheduling. Background technique [0002] The scheduling function in HSUPA (High Speed ​​Uplink Packet Access, High Speed ​​Uplink Packet Access) is mainly completed by the MAC-e (the entity that processes the HSUPA uplink user plane) at the base station side. The core idea of ​​HSUPA scheduling is to prevent too many UEs (User Equipment, user equipment, also called terminals) from accessing too high a rate, thereby causing interference to the system, that is, to suppress uplink interference as much as possible. [0003] Taking a scheduling cycle as an example, the process of uplink scheduling (that is, HSUPA scheduling) is as follows: [0004] Step 1. The UE sends a scheduling request message to the base station through E-RUCCH (E-DCH Random access Uplink C...
