A scheduling base station and system combining pucch cycle

Abstract

The present invention discloses a scheduling base station and system combined with a PUCCH cycle. The scheduling base station includes: a scheduling configuration module configured to configure the UE's downlink scheduling cycle according to the UE's PUCCH cycle, wherein the downlink scheduling cycle is the same as the PUCCH cycle; The scheduling calculation module is used to calculate the amount of data that needs to be scheduled in each downlink scheduling period according to the downlink QoS when the base station finishes processing the PUCCH feedback of the UE in the current PUCCH period; the scheduling execution module is used to lag the current PUCCH period. The current downlink scheduling period executes the downlink scheduling of the UE until the scheduling of the amount of data is completed; wherein, the downlink scheduling period lags the time of the PUCCH period, which is the minimum time necessary for the base station to process the PUCCH feedback, and the time unit is a subframe, and the downlink scheduling period includes multiple subframes. The invention can make full use of air interface frequency spectrum resources.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular, to a scheduling base station and system combined with a PUCCH period. Background technique [0002] In an existing LTE communication system, a UE (User Equipment, user equipment) periodically feeds back parameters such as channel quality of a downlink channel through PUCCH resources, and the base station processes the feedback channel quality and saves it. [0003] When performing downlink scheduling authorization, the base station performs downlink scheduling authorization on the UE according to the QoS (Quality of Service, quality of service) of the UE and the stored channel quality. Although there is no problem with this authorization method, the biggest feature of wireless communication is that the channel quality of the wireless channel changes all the time, and the channel in use can never be used for transmission. Fortunately, although the channel...

[0004] However, the existing air interface downlink scheduling authorization method only considers the QoS requirements, does not consider the accuracy of the channel quality of the downlink channel fed back by the UE, and does not consider the feedback period of the PUCCH resource, resulting in a relatively large deviation between the channel usage time and the channel measurement time. In the case of a relatively large deviation, if the actual channel quality is better than the measurement result, the air interface throughput will decrease. If the actual channel quality is lower than the measurement result, retransmission will occur, which will also cause the air interface throughput to decrease.
