Description
Technical field
This application involves the transmission plans in wireless communication system, more particularly to support wireless relay transmission
(Transmission) method and apparatus.
Background technique
Third generation cooperative partner program (3GPP-3rd Generation Partner Project) R (Release, hair
Cloth) propose in 9 layer 3 (Layer-3) the base station relaying (Relay) scheme.Relay base station is for UE (User
Equipment, user equipment) for have the function of ordinary base station, independent scheduling data and downlink HARQ- can be sent
ACK (Hybrid AutomaticRepeat reQuest, hybrid automatic repeat-request).
In traditional 3GPP system, data transmission occurs between base station and UE.In 3GPP R12, D2D (Device
To Device, equipment room) it communicates and is set up the project and discussed, the essential characteristic of D2D is that the data between UE is allowed to transmit.?
In 3GPP R13, eD2D (Enhancements to LTE Device to Device) is set up the project, and is mainly characterized by introducing
UE relays (Relay) function.In eD2D, trunk subscriber equipment (Relay UE) relays remote user equipment (Remote UE)
Data exchange between base station.
In 3GPP RAN (Radio Access Network, wireless access network) #69 plenary session, NB-IOT
(NarrowBand Internet of Things, narrowband Internet of Things) is set up the project.Further, in RAN#71 plenary session of 3GPP
Upper (RP-160655), for FeD2D (the Further Enhancements to LTE Device of IoT and wearable device
To Device, LTE D2D's further enhances) it is set up the project.In FeD2D, D2D communication may pass through the aerial of similar NB-IoT
Interface is realized.
The typical application scenarios of one of FeD2D are exactly that there are multiple wearable devices around an intelligent terminal.
Intelligent terminal relays wearable device to the data exchange of base station, i.e., intelligent terminal and wearable device are respectively as Relay UE
With Remote UE.
Summary of the invention
R12 and R13D2D transmits the scene mainly for public safety (Public Safety), therefore passes in design data
When defeated, it is all made of the mode of repetition transmission, and the transmission between UE and UE is without the concern for the influence of mobility (Mobility),
Transmission is accordingly to be regarded as independent transmission every time.For FeD2D, it is contemplated that spectrum efficiency and transmission reliability are taken into account, Relay UE
The data or control information of Remote UE can be relayed, and then are obtained because of path loss between Relay UE and Remote UE
(Pathloss) smaller and bring performance gain and power consumption saving.
Original design intention based on FeD2D can be used there are two types of scheme at present.The first scheme is that eNB is maintained
The control plane of Remote UE, i.e. eNB directly send scheduling information to Remote UE, and eNB is directly sent to Remote UE
Downlink data；And upstream data (and control) information of Remote UE is forwarded by the scheduling of eNB by Relay, the spy of the program
Point is relatively simple to the design of Remote UE and Relay UE.Another scheme is that Relay UE directly transmits scheduling information
Remote UE is given, the scheduling information can be Relay UE oneself generation, be also possible to what eNB was indirectly controlled, and
The characteristics of data (and control) information of Relay UE relaying Remote UE, the program is that physical layer design change is smaller.Pass through
To the two schemes the study found that the first scheme channel quality for being more suitable for Remote UE and Relay UE and eNB is preferable
The case where, and second scheme is then more suitable Remote UE positioned at from the remote position eNB.In view of two schemes can
Bring system gain, how according to Remote UE, the channel conditions between RelayUE and eNB three reasonably select transmission side
Case, it will be a problem to be solved.
The application provides solution regarding to the issue above.It should be noted that in the absence of conflict, the application
Embodiment and embodiment in feature can arbitrarily be combined with each other.For example, in embodiment and embodiment in the UE of the application
Feature can be applied in base station, vice versa.In another example the D2D of the application, which sends UE, (sends nothing on D2D chain road
Line signal) in embodiment and embodiment in feature can be applied to D2D receive UE (receive the nothing on D2D chain road
Line signal) in, vice versa.Further, although the original intention of the application is that (i.e. D2D transmission is based on narrowband for FeD2D
), the scheme of the application is also applied for broadband D2D relaying (i.e. D2D transmission is broadband-based).

Channel quality of two nodes to the first node.Second information is used to indicate the first node between the UE
Channel quality.First instruction is used to indicate that the first information and second information meet corresponding to specified criteria
Index.
In the relay transmission based on D2D, because transmission is the transmission for the purpose of public safety (Public Safety)
UE does not need to consider control power consumption, and system also goes to receive without the concern for which UE more can efficiently and more save function
Rate.Therefore, system and base station do not need the more appropriate Relay UE in selection position, i.e., lesser with Remote UE path loss
Relay UE carries out relay transmission.In FeD2D, because the power consumption of Remote UE and the implementation complexity of system are to need to examine
The problem of worry, above-mentioned second wireless singal and the second information are to be used to Relay UE obtain Remote UE to Relay UE's
Channel quality relevant information, and report to eNB, to help eNB to go that suitable Relay UE is selected to provide to the Remote UE
Relay services.Simultaneously, it is contemplated that the coverage area of the following eNB can gradually expand, when Remote UE farther out from eNB when, from
Relay UE directly obtains scheduling information, will be highly efficient.Therefore, Remote UE will also be used to indicate eNB to Remote UE
The first information of channel quality be sent to Relay UE, RelayUE according to the first information with the second information, the first instruction of confirmation
And it is sent to eNB, to report Remote UE, channel conditions between Relay UE and eNB three to base station, and help base station
The mode reasonably transmitted is selected, and selects suitable Relay UE for Remote UE.
