Abstract

Embodiments of the present invention provide a transmission data processing method and devices. The transmission data processing method includes: determining, by user equipment UE, processing indication information according to a type of buffered uplink data, and generating a buffer status report; and sending, by the UE, the buffer status report to a base station eNB, so that the eNB performs scheduling and uplink transmission resource allocation on the UE according to the processing indication information. The transmission data processing method and the devices provided in the embodiments of the present invention avoid a defect that air interface resources cannot be utilized appropriately and effectively when a granularity of a reported buffer status report is per logic channel group, thereby improving effects of scheduling and resource allocation that are performed on UE.

determining, by user equipment (UE), processing indication information according to a type of buffered uplink data, and generating a buffer status report (BSR), wherein the BSR carries the processing indication information; and sending, by the UE, the BSR to an evolved NodeB (eNB), so that the eNB performs scheduling and uplink transmission resource allocation on the UE according to the processing indication information.

2 . The transmission data processing method according to claim 1 , wherein the determining, by UE, processing indication information according to a type of buffered uplink data, and generating a BSR comprises:
if it is learned, by means of determining, that the buffered uplink data comprises low-priority data, generating, by the UE, the BSR carrying processing indication information used to indicate that the uplink data is low-priority data.

3 . The transmission data processing method according to claim 2 , wherein the BSR is a short BSR or a truncated BSR, the processing indication information is bit indication information, and content of a reserved bit of a Media Access Control (MAC) layer subheader in the BSR is the bit indication information.

4 . The transmission data processing method according to claim 2 , wherein content of a logic channel identity field of a MAC layer subheader of the BSR is the processing indication information.

5 . The transmission data processing method according to claim 1 , wherein before the determining, by UE, processing indication information according to a type of buffered uplink data, and generating a BSR, the method further comprises:
