Problems solved by technology

[0022] Comparing the situation of UE1 and UE2 above, it can be seen that the BSR reporting mechanism in the current 3GPP LTE R8 specification is used, and the RB status reported by the UE to the base station is not accurate enough, causing the base station to When the UE allocates uplink resources, there is a problem that the allocation is unreasonable and the utilization efficiency of the uplink resources is not high

Embodiment 1

[0076] Embodiment 1 of the present invention provides a method for transmitting radio bearer status, such as Figure 5 shown, including:

[0077] Step S501, after performing uplink resource allocation in the current transmission cycle, determine the number of tokens in the token bucket corresponding to the radio bearer.

[0078] Step S502. According to the determined number of tokens, send to the base station first status information indicating that the number of tokens is greater than zero; or send second status information indicating that the number of tokens is not greater than zero to the base station.

[0079] Preferably, the step S501 above further includes: when the number of tokens is greater than zero, comparing the number of tokens with the buffered data size of the radio bearer; when the number of tokens is not greater than zero, comparing The amount of cached data to host with a size of zero.

[0080] Correspondingly, in the above step S502, according to the comp...

Embodiment 2

[0120] Embodiment 2 of the present invention provides a method for transmitting radio bearer status, such as Figure 7 shown, including:

[0121] Step S701 , after performing uplink resource allocation in the current sending period, determine the number of tokens in the token bucket corresponding to the radio bearer; and compare the number of tokens with the buffered data volume of the radio bearer.

[0122] Step S702. According to the determined number of tokens and the comparison result, send to the base station first status information indicating that the number of tokens is greater than zero and that the number of tokens is less than the buffered data volume of the radio bearer; or send Sending second state information not greater than zero or the number of tokens not less than the amount of buffered data of the radio bearer to the base station; or

[0123] According to the determined number of tokens and the comparison result, send the third status information to the bas...

Embodiment 3

[0146] Embodiment 3 of the present invention provides a method for transmitting radio bearer status, such as Figure 9 shown, including:

[0147] Step S901, after performing uplink resource allocation in the current transmission cycle, determine the buffered data volume of the radio bearer; and

[0148] When the amount of cached data of the radio bearer is greater than zero, determine the number of tokens in the token bucket corresponding to the radio bearer; and

[0149] When the number of tokens is greater than zero, compare the number of tokens with the buffered data volume of the radio bearer.

[0150] Step S902. According to the determined buffered data amount of the radio bearer, send first status information indicating that the buffered data amount of the radio bearer is not greater than zero; or

[0151] According to the determined number of tokens, sending to the base station second status information indicating that the number of tokens is not greater than zero and...

Abstract

The invention discloses a radio bearer state transmitting method and a device. The method comprises the following steps: determining the token number of token buckets corresponding to radio bearer after executing uplink resource allocation in the current transmitting period; transmitting first state information expressing that the token number is more than 0 to a base station according to determined token number; or transmitting second state information expressing that the token number is not more than 0 to the base station. By using the method and the device, the precision of radio bearer state reported by UE (User Equipment) can be improved, further the base station can more reasonably allocate uplink resources and the utilization efficiency of the uplink resources can be improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for transmitting radio bearer status. Background technique [0002] The existing 3GPP LTE R8 specification 3GPP TS 36.321V8.3.0 defines the format and content of the media access control layer protocol data unit MAC PDU, such as figure 1 shown. The service data of each radio bearer (Radio Bearer) is filled in the MAC SDU (MAC Service Data Unit) field of the media access control layer, and each MAC SDU field has a The sub-header corresponds to it, where the content of the "R" field is a reserved bit, and the "E" field indicates an extended field to indicate whether there are more fields defined in the MAC header; the "L" field indicates the corresponding The length of the MAC SDU or MAC control element, the length of "L" is identified by the "F" field; the "LCID" field indicates the logical channel identifier corresponding to the MAC SD...
