Description

A kind of method and apparatus of arrowband cellular communication
Technical field
The present invention relates to the transmission plan in wireless communication system, wireless relay is more particularly to supported The method and apparatus for transmitting (Transmission).
Background technology
Third generation cooperative partner program (3GPP-3rd Generation Partner Project) The side of layer 3 (Layer-3) relaying (Relay) base station is proposed in R (Release, issue) 9 Case.Relay base station possesses ordinary base station for UE (User Equipment, user equipment) Function, scheduling data that can be independent and send descending HARQ-ACK (Hybrid Automatic Repeat reQuest, hybrid automatic repeat-request).
In traditional 3GPP system, data transfer occurs between base station and UE.In 3GPP R12 In, D2D (Device to Device, equipment room) communications are set up the project and discussed, D2D sheet Matter feature is to allow the data transfer between UE.In 3GPP R13, eD2D (Enhancements To LTE Device to Device) to be set up the project, it is mainly characterized by introducing UE relayings (Relay) Function.In eD2D, trunk subscriber equipment (Relay UE) relaying remote user equipment (Remote UE) the data exchange between base station.
In 3GPP RAN (Radio Access Network, wireless access network) #69 plenary session, NB-IOT (NarrowBand Internet of Things, arrowband Internet of Things) is set up the project.Enter One step, in RAN#71 plenary session of 3GPP (RP-160655), for IoT and wearable FeD2D (Further Enhancements to LTE Device the to Device, LTE of equipment D2D's further enhances) set up the project.In FeD2D, D2D communications may pass through similar NB-IoT Air interface realize.
The typical application scenarios of one of FeD2D be exactly exist around an intelligent terminal it is multiple Wearable device.Intelligent terminal relays wearable device to the data exchange of base station, i.e. intelligent terminal It is Relay UE and Remote UE respectively with wearable device.
The content of the invention
Release 12D2D transmit the scene mainly for public safety (Public Safety), Therefore when design data is transmitted, by the way of repeating to transmit.Terminal device and terminal device Between there is no link circuit self-adapting (Link Adaptation), also without CSI (Channel State Information, channel condition information) feedback.For FeD2D, it is contemplated that spectrum efficiency and biography Defeated reliability is taken into account, the CSI between terminal device and terminal device, i.e. Relay UE and Remote UE CSI by base station, it is necessary to obtained, to carry out the suitable of link circuit self-adapting and modulation coding mode Match somebody with somebody.
A kind of intuitively solution is the scheme for reusing the relay base station in 3GPP R9, i.e. Relay UE possesses the function of relay base station, and all Remote UE scheduling is realized by Relay UE.
