Problems solved by technology

[0013] For R11 and previous versions of UEs, BSR reporting is based on the UE reporting the buffer size of each logical channel group, but if R12 introduces inter-eNB aggregation, two eNBs can perform uplink scheduling separately. Obviously, the current BSR method It is not applicable to scenarios where inter-eNB aggregation is introduced
[0014] To sum up, currently, there is no solution for buffer status reporting in inter-eNB aggregation scenarios

example 1

[0198] Example 1. Per UE triggers reporting, but reports to the base stations participating in the aggregation and performing scheduling at the same time. The BSR information of per UE is reported, but the buffer content corresponding to each RB or LCG may be different.

[0199] Step 1: Obtain configuration information:

[0200] The UE obtains the following configuration information:

[0201] The UE needs to know the correspondence between the aggregated cells and the base station through RRC signaling;

[0202] The UE needs to know the correspondence between the RB and the transmission base station through RRC signaling;

[0203] The UE learns the retxBSR-Timer and periodicBSR-Timer configurations through RRC signaling. The BSR-related parameter configuration base station may be a participating macro base station or a local node participating in aggregation.

[0204] The configuration information can be sent by any base station participating in the aggregation, or the base...

example 2

[0215] Example 2: per UE triggers reporting, but simultaneously reports to base stations participating in aggregation and performing scheduling respectively, and the reporting for each eNB only includes the BSR information of the RB or LCG scheduled by the eNB.

[0216] Step 1: Obtain configuration information:

[0217] The UE obtains the following configuration information:

[0218] The UE needs to learn the correspondence between the aggregated cells and the base station through RRC signaling.

[0219] The UE needs to know the corresponding relationship between the RB and the transmitting base station through RRC signaling.

[0220] The UE learns the retxBSR-Timer and periodicBSR-Timer configurations through RRC signaling. The BSR-related parameter configuration base station may be a participating macro base station or a local node participating in aggregation.

[0221] The configuration information can be sent by any base station participating in the aggregation, or the ...

example 3

[0232] Example 3: BSR triggering and reporting of per eNB.

[0233] Step 1: Obtain configuration information:

[0234] The UE obtains the following configuration information:

[0235] The UE needs to know the correspondence between the aggregated cells and the base station through RRC signaling;

[0236] The UE needs to know the corresponding relationship between the RB and the transmitting base station through RRC signaling.

[0237] Each base station participating in aggregation or participating in aggregation and scheduling configures the retxBSR-Timer and periodicBSR-Timer corresponding to the base station for the UE through RRC signaling.

[0238] The first two configuration information can be sent by any base station participating in the aggregation, or the base station responsible for mobility management, or the base station providing macro coverage, or the base station responsible for BSR reception, or the base station that decides whether the RB performs bearer sepa...

Abstract

The embodiment of the invention relates to the technical field of wireless communication, in particular to a method, system and device for buffer area state report. The method, system and device for buffer area state report are used for conducting buffer area state report according to the scene of inter-eNB aggregation. The method for buffer area state report comprises the following steps that user equipment aggregating resources of multiple network side devices determines buffer area state information; the user equipment reports the buffer area state information to at least one network side device which participates in aggregation. Due to the fact that the user equipment aggregating the resources of the multiple network side devices reports the buffer area state information to at least one network side device which participates in aggregation, and therefore buffer area state report based on the scene of inter-eNB aggregation is achieved; further, multiple base stations can obtain the buffer area state information in the situation of aggregation between the base stations, and therefore resource scheduling is achieved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a buffer state reporting method, system and equipment. Background technique [0002] The peak rate of the LTE-A (Long Term Evolution-Advanced, long-term evolution upgrade) system is greatly improved compared with LTE, and it is required to reach 1Gbps in the downlink and 500Mbps in the uplink. At the same time, the LTE-A system requires good compatibility with the LTE system. The LTE-A system introduces a CA (Carrier Aggregation, Carrier Aggregation) technology based on the need to increase the peak rate, be compatible with the LTE system, and make full use of spectrum resources. [0003] The carrier aggregation technology enables a terminal to work simultaneously on multiple cells. These cells may be continuous or discontinuous in the frequency domain, and the bandwidth of each cell may be the same or different. In order to maintain compatibility with the LTE sy...
