Problems solved by technology

[0015] If the air interface rate of the user is calculated after receiving the feedback message according to the method shown in formula (2), then, as figure 1 As shown, it takes 8 TTIs from scheduling to receiving the feedback message. If the channel environment of other users in the same cell does not change much during this period, then from figure 1 The first TTI shown is to schedule a user, assuming that user A starts, and the subsequent 7 TTIs will also be scheduling user A, unless the cache of user A is scheduled, otherwise the scheduling for user A will last at least 8 TTIs, That is, if the scheduling interval is too large, the user plane transmission delay of other users increases. That is to say, even if other users have

Abstract

The invention provides a method for obtaining a radio interface rate of a user, which includes: for any user A, permitted data transmission amount within a present transmission time interval (TTI) is determined; and the radio interface rate of the user A corresponding to the present TTI is determined in a smooth filter mode according to the permitted data transmission amount within the present TTI. The method and device can reduce user surface transmission time delay and improve handling capacity of a subdistrict.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method and device for acquiring user air interface rate. Background technique [0002] In the evolved high-speed packet access (HSPA+, High Speed ​​Packet Access Plus) system, the base station (NodeB) usually uses a proportional fair (PF, Proportional Fair) scheduling algorithm to schedule users, mainly because the PF scheduling algorithm comprehensively considers The user's channel environment and service fairness among users can achieve a certain compromise between system throughput and service fairness. To implement the PF scheduling algorithm, it is first necessary to obtain the air interface rate of the user. [0003] In the prior art, the user's air interface rate can be acquired in the following manner, that is, calculation: [0004] R ‾ ( t ) = B ...
