Embodiment Construction

[0048] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings. The configuration information sent by the network side or the UE side high layer is aimed at the uplink logical channel and notifies the UE MAC layer whether the uplink data of each uplink logical channel is allowed to use contention resources. According to this, the UE MAC will allow the uplink data of the uplink logical channel using the contention resource to be transmitted on the authorized contention resource, and forbid the uplink data of the uplink logical channel using the contention resource to be transmitted on the authorized contention resource. The configuration principle is that uplink data that is expected to shorten the delay and can tolerate the transmission characteristics of the contention resource is allowed to use the contention resource.

[0049] Wherein, the method for notifying the UE MAC layer of whether the uplink data of th...

Abstract

A method and device for contention-based uplink data transmission are disclosed in the present invention. The present invention can solve the problem that the overall performance of uplink data transmission can not be ensured well while the transition time of a state transition process is reduced. The method includes that: a User Equipment (UE) Medium Access Control (MAC) layer obtains configuration information which is used to indicate that whether the uplink data of each uplink logic channel are allowed to use contention resources; when the contention resources are needed to be used, the UE MAC layer allows the uplink data, which are allowed to use the contention resources, to be transmitted on the authorized contention resources, and forbids the uplink data, which are not allowed to use the contention resources, to be transmitted on the authorized contention resources. Just because the uplink data are processed respectively according to whether the uplink data are allowed to use the contention resources, for the data that can obtain larger gains by shortening time delay, the efficiency and success rate of using the contention resources by the data are improved, the fact that the other data enhance the collision probability on the contention resources is avoided, and the transmission success rate is ensured, and the transmission performance of the uplink data is improved.

Description

technical field [0001] The invention belongs to the technical field of communications, in particular to a contention-based uplink data transmission method and device. Background technique [0002] In an LTE-Advanced (Long Term Evolution, long-term evolution) system, in order to support a shorter transition delay from a dormant state (Dormant) to an active state (Active), a UE (User Equipment, User Equipment) in a dormant state (Dormant) The device) has an RRC (Radio Resource Control, radio resource control) connection with an eNB (evolved Node B, evolved base station) and an established radio bearer, but because there is no uplink resource allocation and data transmission, it is currently in a temporary Inactive state. [0003] Taking the state transition triggered by the uplink data of the UE in the synchronous state as an example, the process is as follows figure 1 Shown include the following steps: [0004] Step 11: Delay and wait for the next SR (Scheduling Request, s...
