BSR reporting method, evolved node B, UE and computer storage medium

An Evolved Node B (eNB), comprising:

• a sending module, configured to send an allocation rule for buffer data of a radio bearer which are to be allocated among eNBs to User Equipment (UE), the allocation rule comprising information about an allocation proportion or comprising information about an allocation proportion and an applicable condition of the allocation proportion;
• wherein the information about the allocation proportion comprises at least one of followings:
• the information about the allocation proportion is a proportion relationship of specific bearers among the eNBs, or the information about the allocation proportion is a proportion relationship of specific bearers belonging to Logical Channel Groups (LCGs) among the eNBs;
• the specific bearers are all or a part of Data Radio Bearers (DRBs) or signalling radio bearers;
• wherein the information about the allocation proportion and the applicable condition of the allocation proportion are that:
• when a size of the buffer data is not larger than a predetermined value, the buffer data is sent from a specified eNB;
• or, the buffer data is sent from an eNB where a large proportion of data of the radio bearer according to a predetermined allocation proportion is to be sent;
• the predetermined allocation proportion comprises at least one of followings:
• a proportion relationship of specific bearers among the eNBs;
• or a proportion relationship of specific bearers belonging to Logical Channel Groups (LCGs) among the eNBs;
• the specific bearers are all or a part of Data Radio Bearers (DRBs) or signalling radio bearers;
• and
• a receiving module, configured to receive a Buffer Status Report (BSR) from the UE, the BSR being determined by the UE according to the allocation rule.

A method for sending a Buffer Status Report (BSR), comprising:

• receiving, by User Equipment (UE), from an Evolved Node B (eNB) an allocation rule for buffer data of a radio bearer which are to be allocated among eNBs, the allocation rule comprising allocation proportion information or comprising allocation proportion information and an applicable condition of the allocation proportion information;
• wherein the allocation proportion information comprises at least one of followings:
• the information about the allocation proportion is a proportion relationship of specific bearers among the eNBs;
• or the information about the allocation proportion is a proportion relationship of specific bearers belonging to Logical Channel Groups (LCGs) among the eNBs;
• the specific bearers are all or a part of Data Radio Bearers (DRBs) or signalling radio bearers;
• wherein the allocation proportion information and the applicable condition of the allocation proportion information are that:
• when a size of the buffer data is not larger than a predetermined value, the buffer data is sent from a specified eNB;
• or, the buffer data is sent from an eNB where a large proportion of data of the radio bearer according to a predetermined allocation proportion is to be sent;
• the predetermined allocation proportion comprises at least one of followings:
• a proportion relationship of specific bearers among the eNBs;
• or a proportion relationship of specific bearers belonging to Logical Channel Groups (LCGs) among the eNBs;
• the specific bearers are all or a part of Data Radio Bearers (DRBs) or signalling radio bearers;
• and
• sending, by the UE, a BSR according to the allocation rule, the BSR being determined by the UE according to the allocation rule.

User Equipment (UE), comprising:

• a receiving module, configured to receive from an Evolved Node B (eNB) an allocation rule for buffer data of a radio bearer which are to be allocated among eNBs, the allocation rule comprising allocation proportion information or comprising allocation proportion information and an applicable condition of the allocation proportion information;
• wherein the allocation proportion information comprises at least one of followings:
• the information about the allocation proportion is a proportion relationship of specific bearers among the eNBs, or the information about the allocation proportion is a proportion relationship of specific bearers belonging to Logical Channel Groups (LCGs) among the eNBs;
• the specific bearers are all or a part of Data Radio Bearers (DRBs) or signalling radio bearers;
• wherein the allocation proportion information and the applicable condition of the allocation proportion information are that:
• when a size of the buffer data is not larger than a predetermined value, the buffer data is sent from a specified eNB;
• or, the buffer data is sent from an eNB where a large proportion of data of the radio bearer according to a predetermined allocation proportion is to be sent;
• the predetermined allocation proportion comprises at least one of followings:
• a proportion relationship of specific bearers among the eNBs;
• or a proportion relationship of specific bearers belonging to Logical Channel Groups (LCGs) among the eNBs;
• the specific bearers are all or a part of Data Radio Bearers (DRBs) or signalling radio bearers;
• and
• a sending module, configured to send a Buffer Status Report (BSR) reported by the UE to the eNB, the BSR being determined by the UE according to the allocation rule.
