Problems solved by technology
[0004] When the priority of the logical channel to which the uplink data is being sent is higher than the priority of the periodic BSR, if the periodic BSR is reported to the base station with a priority higher than the priority of the logical channel to which the uplink data belongs, it will cause high-priority logic Segmentation of uplink data in the channel will also cause delayed transmission of uplink data in the high-priority logical channel
In addition, when the base station receives the periodic BSR sent by the UE before sending all the multiple uplink grants to the UE, the amount of uplink data carried in the periodic BSR also includes the amount of uplink data corresponding to the unsent uplink grants, resulting in conventional The uplink data corresponding to the BSR partly overlaps with the uplink data corresponding to the periodic BSR. Therefore, when the overlapping uplink data is scheduled based on the periodic BSR, scheduling resource redundancy is caused.

Embodiment Construction
[0149] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0150] figure 1 It is a schematic structural diagram of the first data transmission device provided by the embodiment of the present invention. see figure 1 , the device consists of:
[0151] The processing unit 101 is configured to obtain the priority of the logical channel to which the uplink data being sent belongs, and obtain the priority of the logical channel to which the periodic BSR belongs, when a trigger instruction to trigger a periodic buffer status report BSR is received;
[0152] The processing unit 101 is further configured to determine whether the priority of the uplink data is greater than the priority of the periodic BSR based on the priority of the logical channel to which the uplink data belongs and the priority o...

Embodiments of the present invention provide a data transmission method and device, which relate to the field of wireless communication. The method includes: when receiving a trigger instruction to trigger a periodic BSR, acquire the priority of the logical channel to which the uplink data being sent belongs, and acquire the periodic BSR The priority of the logical channel to which the uplink data belongs; based on the priority of the logical channel to which the uplink data belongs and the priority of the logical channel to which the periodic BSR belongs, determine whether the priority of the uplink data is greater than the priority of the periodic BSR; when the priority of the uplink data is greater than that of the periodic BSR Priority, the uplink data is sent to the base station with a priority higher than that of the periodic BSR; when the priority of the uplink data is lower than the priority of the periodic BSR, the priority of the periodic BSR is higher than that of the uplink data sent to the base station. The present invention avoids segmentation of uplink data in the high-priority logical channel, avoids delayed transmission of uplink data in the high-priority logical channel, and avoids redundancy of scheduling resources.
Description
technical field [0001] The invention relates to the field of wireless communication, in particular to a data transmission method and equipment. Background technique [0002] In the Long Term Evolution (English: Long Term Evolution; abbreviation: LTE) system, in order to facilitate the base station to know the size of the user equipment (English: User Equipment; abbreviation: UE) uplink data volume, the UE needs to report the cache status report (English: Buffer Status Report; referred to as: BSR), the base station learns the size of the uplink data cached by the UE side through the BSR, and based on the size of the uplink data, allocates uplink resources for the UE, so that the UE can send the uplink data through the allocated uplink resources to the base station. [0003] Currently, there are three ways for the UE to report the BSR: a regular (regular) BSR, a period (period) BSR and a padding (padding) BSR. When there is new uplink data buffered in the logical channel of ...
