Embodiment Construction

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is only some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] The present invention provides an uplink logical channel scheduling method, such as figure 1 As shown, the method includes:

[0038] S11. Calculate the duration of this scheduling according to the DCI sent by the base station;

[0039] S12. Determine the uplink resource available for data transmission corresponding to each TTI accord...

Abstract

The invention provides an uplink logic channel scheduling method and device and user equipment. The method comprises the steps that the duration of current scheduling is calculated according to the DCI transmitted by a NodeB; the uplink resource corresponding to each TTI and capable of being used for data transmission is determined according to the UL grant transmitted by the NodeB; the guaranteeddata volume of each logic channel in current scheduling is calculated according to the duration of current scheduling; and the uplink resource required for the guaranteed data volume of current scheduling is allocated for each logic channel in turn according to the descending order of the priority of the logic channels, and the remaining uplink resource is allocated for each logic channel to thegreatest extent according to the descending order of the priority of the logic channels if there is remaining uplink resource after the uplink resource required for the guaranteed data volume of current scheduling is allocated for each logic channel. The guaranteed data volume of multiple TTI of the same logic channel can be transmitted in the same TTI in a centralized way so that the number of the generated MAC SDU can be reduced and the header overhead of the MAC PDU set packet can be reduced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an uplink logical channel scheduling method, device and user equipment. Background technique [0002] In LTE (Long Term Evolution, long-term evolution), UE (User Equipment, user equipment) is the sending end of uplink data transmission, and the base station allocates uplink authorization (UL grant) and uplink resources for UE, and determines the total uplink data that UE can send. The amount of data. The uplink data scheduling of each logical channel in the UE is completed by the UE. Each logical channel is configured with a corresponding absolute priority. Uplink resources are used to send data of high priority logical channels first. Before scheduling, each logical channel is configured with PBR (Prioritized Bit Rate, priority bit rate), and the logical channel j is defined to ensure that the amount of data sent is B j , then each TTI (Transmission Time...
