Embodiment Construction

[0039] The inventive concept of the present invention is: the base station sends uplink authorization information to the UE, indicating the position of the contention resource (that is, the contention-based transmission resource) and the transmission method of sending uplink data on the contention resource; The UE sends uplink data according to the indicated transmission method; the base station returns a response message to the UE, indicating whether it has successfully received the data on the contention resource; after receiving the response message, the UE confirms that its uplink data transmission on the contention resource is successful or not according to the response message fail.

[0040] After adopting the above method, the UE can judge the success or failure of the uplink CB transmission according to the response message sent by the base station. When the UE uplink data is successfully transmitted, the UE will not retransmit blindly, thereby avoiding the eNB from rec...

Abstract

The invention discloses a contention-based uplink data transmission method and a contention-based uplink data transmission system. Resource wasting is avoided, and a data transmission delay is shortened. The uplink data transmission method comprises that: a base station transmits uplink authorization information to user equipment (UE) to indicate the position of contention resources and a transmission way of transmitting uplink data on the contention resources; the UE transmits the uplink data according to the indicated transmission way on the contention resources indicated by the uplink authorization information; the base station returns a response message to the UE to indicate whether the data on the contention resources are successfully received or not to the UE; and after receiving the response message, the UE confirms whether the transmission of the uplink data on the contention resources is successful or failed according to the response message.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a contention-based uplink data transmission method and system. Background technique [0002] In a wireless communication system, a user equipment (User Equipment, UE) generally needs to utilize contention (Contention) resources at an initial stage of data transmission. There are mainly two scenarios: one is to perform random access when the UE accesses the network for the first time, and the other is to enter the dormant state during the data gap after the UE has accessed the network ( dormant) to save the battery cost of the UE and the resource cost of the network. The network may not reserve resources for the UE or only reserve a few resources. When there is uplink data to be sent, the UE uses random access or the reserved A small number of resources, such as sending signaling on a dedicated signaling channel to notify the network, so as to obtain subsequent uplink transm...
