Embodiment Construction

[0046] 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.

[0047] Wherein, the method for notifying the UE MAC layer of whether the uplink data of th...

Abstract

The invention discloses a contention-based uplink data transmission method and a contention-based uplink data transmission device, which aim to solve the problem that the overall performance of uplink data transmission cannot be ensured well at the same time of shortening the switching time of a status switching process. The method comprises that: a user equipment medium access control (UE MAC) layer acquires configuration information which is used for indicating whether the uplink data of each uplink logic channel allows the utilization of contention resources or not, and if the contention resources are required to be utilized, transmits the uplink data allowing the utilization of the contention resources on contention grants and forbids the transmission of the uplink data not allowing the utilization of the contention resources on the contention grants. Processing is performed according to whether to allow the utilization of the contention resources or not respectively, the method and the device improve the efficiency and success rate of the utilization of the contention resources for the data capable of obtaining relatively higher gain by shortening a time delay, avoid the increasing of probability of collision of other data on the contention resources, ensure the transmission success rate of the other data and improve the overall performance of the uplink data transmission.

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...
