Buffer status report transmitting and receiving method, user equipment and base stations

Abstract

The embodiment of the invention provides a buffer status report transmitting and receiving method, user equipment and base stations. The method comprises the following steps that: instruction information which is transmitted by a macro base station and is used for requesting the user equipment (UE) to transmit a buffer status report is received; and the buffer status report (BSR) is transmitted to the macro base station and / or at least one small base station according to the instruction information, wherein the macro base station and / or the at least one small base station jointly serve for the user equipment (UE), the service range of the macro base station being larger than the service range of each small base station in the at least one small base station. With the buffer status report transmitting and receiving method, the user equipment and the base stations of the invention adopted, the macro base station and the small base stations can be accurately informed of the buffer status report reported by the user equipment (UE) under a situation that the macro base station and the small base stations simultaneously work for the same data service transmission of a user, and therefore, the macro base station and the small base stations can perform scheduling timely.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a buffer status report sending and receiving method, user equipment and a base station. Background technique [0002] With the development of mobile communication technology and the increase of the number of people using mobile data services, the load of existing macro cells is getting heavier and heavier. In order to provide users with better services, the 3rd Generation Partner Project (the 3rd Generation Partner Project) , referred to as: 3GPP) introduced a carrier aggregation (Carrier Aggregation, referred to as: CA) technology. [0003] In the CA technology, multiple base stations may be used to provide services for the same UE, for example, a small base station (Small cell for short) and a macro base station (macro for short) may be used to cooperate to provide services for the UE. Small base stations, such as home base stations (hom...

Problems solved by technology

[0004] However, in the scenario where the small base station and the macro base station are responsible for the transmission of the same user data service at the same time, the user equipment (User Equipment, referred to as: UE) needs to send uplink data to the small base station and the macro base station respectively, and the small base station and the macro base station in the prior art cannot Accurately know the buffer status report (Buffer Status Report, hereinafter referred to as: BSR) reported by the UE, because the data of the UE is sent to the small base station and the macro base station respectively, and the BSR of all the data in the UE cache cannot be applied to multiple base stations serving the UE Scenarios, resulting in the failure of timely scheduling of small base stations and macro base stations
