Embodiment 1

[0048] UE reports as Figure 5 The shown Long BSR MAC CE is for the macro base station. After the macro base station receives the BSR shown in the above figure, it can know that the buffer status index value of logical channel group 0 is 10 (the corresponding number of bits is 36-42), and the buffer status index value of logical channel group 1 is 20 (the corresponding bit number The number is 171-200), and the cache status index values ​​of logical channel groups 2 and 3 are both 0 (no data to be transmitted). The macro base station performs resource allocation. For logical channel group 0, the amount of uplink data to be transmitted allocated to the macro base station cell is 14-17 bits (the corresponding cache status index value is 4), and the amount of uplink data to be transmitted allocated to the micro base station cell is 14-17 bits. is 22-25 bits (the corresponding buffer status index value is 7); for logical channel group 1, the amount of uplink data to be transmitte...

Embodiment 2

[0051] UE reports as Figure 8 The shown Short BSR MAC CE or Truncated BSR MAC CE is for the macro base station. The macro base station receives Figure 8 After the BSR shown, it can be known that the buffer status index value of logical channel group 1 is 10 (the corresponding number of bits is 36-42). The macro base station performs resource allocation. For this logical channel group, the amount of uplink data to be transmitted allocated to the macro base station cell is 14-17 bits (the corresponding buffer status index value is 4), and the amount of uplink data to be transmitted allocated to the micro base station cell is 14-17 bits. It is 22-25 bits (the corresponding cache status index value is 7). After the resource allocation is completed, the macro base station generates such as Figure 9 The signaling shown is similar to the Short BSR MAC CE format and sent to the Femtocell. Afterwards, the macro base station and the micro base station perform uplink scheduling on...

Abstract

The present application discloses a buffer status report (BSR) processing method in a dual connectivity network, including: A. User equipment UE reports BSR to macro base station; B. Macro base station allocates macro base station cells and micro base stations according to the BSR reported by UE The amount of uplink data to be transmitted in the cell; C. The macro base station sends the signaling carrying the amount of uplink data to be transmitted allocated to the micro base station to the micro base station; D. The macro base station and the micro base station are respectively assigned to the cell according to the uplink to be transmitted The amount of data is used to perform uplink scheduling on the UE. This application provides a feasible processing solution for the BSR reported to the UE in the dual connectivity network.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a method for processing a Buffer Status Report (BSR, Buffer Status Report) in a dual connectivity network. Background technique [0002] Dual-connection network is a research hotspot in current wireless communication technology. In dual-connection network communication, the data of the same logical channel can be jointly transmitted by the macro base station and the micro base station, and the UE can send the uplink data of the logical channel to the macro base station and the micro base station. base station, thereby improving the throughput of the UE. [0003] A dual-connection network architecture such as figure 1 shown. In this network, user equipment (UE, User Equipment) maintains an air interface connection with the macro base station and the micro base station at the same time, which means that the macro base station and the micro base statio...
