Description

The instruction of DTD, processing method and device

Technical field

The present invention relates to the communications field, in particular to the instruction of a kind of DTD, processing method and device.

Background technology

At present, at device-to-device (Device-to-Device, referred to as D2D) in communication system, subscriber equipment (UserEquipment, referred to as UE) between when having service needed to transmit, business datum between UE needs not move through the forwarding of base station, but is directly passed through air interface transmission to target UE by data source UE. Fig. 1 is the D2D communication structure schematic diagram according to correlation technique. As shown in Figure 1, this communication pattern has the feature being clearly distinguishable from conventional cellular systems communication pattern, for the short-range communication user that can apply D2D communication mode, D2D transmission not only can save radio spectrum resources, but also the data that can reduce core net transmit pressure, reduce system resource and take, increase the spectrum efficiency of cellular communication system, reduce terminal transmission power consumption, and save network operation cost to a great extent.

In Long Term Evolution (LTE) system, Fig. 2 is the schematic diagram of the LTE system frame structure according to correlation technique. As in figure 2 it is shown, Radio Resource divides resource in time domain in units of radio frames, each radio frames is 10ms, wherein it is possible to comprise 10 subframes. Each subframe is 1ms, and it can be divided into 2 time slots (slot) of 0.5ms, adopts same frame structure in D2D communicates. Medium education (MediumAccessControl in LTE system, referred to as MAC) layer, data between eNB and UE are with MAC Service Data Unit (ServiceDataUnit, referred to as SDU) for the unit control element (ControlElement relevant with MAC layer, referred to as CE) being packaged into Medium Access Control (MAC) Protocol Data Unit (ProtocolDataUnit, referred to as PDU) by certain rule carries out the encapsulated delivery of data jointly. The form of the MACPDU of LTE system is as shown in Figure 3: being divided into MACPDU head (Header) and MACPDU payload (Payload) two parts on the whole, in a MACPDU, head part, front, accepts thereafter effective loading section. Comprising multiple MACPDU head (Sub-header) in MACPDU head, payload part comprises some MACSDU and MACCE, it is also possible to include the certain byte of padding Padding introduced according to the length legislations of MACPDU.

In D2D communication system, being made directly the transmission of data between UE, transmitting terminal UE itself needs to send D2D and controls information, to relevant informations such as the resources that the data signal transmitted of receiving terminal UE instruction uses. Transmitting terminal UE is at D2D link control message (SidelinkControlInformation, referred to as SCI) instruction uses in signaling physics limit link shared channels (PhysicalSidelinkSharedChannel, referred to as PSSCH) resource and relevant control information, indicated PSSCH resource carries out the transmission of D2D data. Transmitting terminal UE indicates the PSSCH sub-frame resources used in PSSCH cycle or physics limit link control channel (PSCCH) cycle in SCI by time-domain resource pattern (TimeResourcePattern, referred to as TRP). Fig. 4 is the schematic diagram being indicated PSSCH sub-frame resources by TRP according to correlation technique. As shown in Figure 4, each TRP indexes corresponding to a unique bitmap pattern (bitmappattern), bitmappattern indicated by TRP, the corresponding subframe that bit bit-identify is " 1 " is namely designated as PSSCH subframe, bitmappattern repeats at PSCCH cycle internal recycle, to reach the sub-frame configuration in the whole cycle is indicated. Transmitting terminal UE can reach the configuration instruction of one or more PSSCH subframes in the cycle by sending once effective SCI information within each cycle. Therefore, the scheduling of PSSCH resource is indicated in units of the cycle by SCI, would be likely to occur certain difference between scheduling of resource instruction and the dynamic business actual demand of so bigger granularity, make the PSSCH subframe of instruction and transmitting terminal UE need Incomplete matching between the data launched. When transmitting terminal UE does not have valid data to launch in all or part of PSSCH subframe indicated, transmitting terminal UE cannot indicate the residue PSSCH subframe not carrying data, and receiving terminal UE needs that under the premise not being explicitly indicated the PSSCH subframe of all configurations carries out detection and receives, so there is certain power dissipation.
