Description
Technical field
The present invention relates to communication technical field, relate in particular to the instruction of control channel under direct mode operationMethod and terminal.
Background technology
Trunked mobile communication system is a kind of advanced mobile command dispatching system, in commander, schedulingEnterprise, cause, industrial and mineral, oil field, farm, airport, public security and army that functional requirement is higherAll bringing into play huge effect in department. TD-LTE (TimeDivisionLongTermEvolution, timesharing Long Term Evolution) technology is the access of new generation broadband mobile communication wirelessTechnology, compared with the wireless access technology of existing 2G, 3G GSM, it has biographyDefeated speed is high, propagation delay time is little, high QoS (QualityofService, service quality) ensuresEtc. feature. Technical at existing TD-LTE, the characteristic of increase group service, realizes TD-LTEWideband digital trunked communication system is the developing direction of trunked communication system. Network-off direct-passing function isA kind of requisite basic function in trunked communication system. Therefore, at TD-LTE broadband numberIn word trunked communication system, realizing network-off direct-passing is very important.
DMO (DirectModeOperation, direct mode operation) refers to that two or more eventuallyDirect communication between end. Under direct mode operation, the communication between two or more terminals withoutBase station and forwarded. When having left network, UE (UserEquipment, subscriber equipment) coversBehind lid district, show and exceed service area, UE just can select the working method of direct mode operation, equipmentAlso can automatically enter direct mode operation. Fig. 1 shows the communication pattern schematic diagram of DMO,(DirectModeUserEquipment, the user under direct-passing mode establishes DM-UE in DMOStandby) between carry out the communication of point-to-point or point-to-multipoint by direct mode air interface. ?In DMO, provide the DM-UE of reference synchronization to be called master control UE; Synchronize with master control UEDM-UE is called subordinate UE.
In the trunked communication system based on TD-LTE technology, DM-UE by air interface withOther DM-UE are connected, and DM-UE can survey other DM-UE in adjacent area, and step by stepSet up multi-hop wireless link, until find target DM-UE, and set up many with target DM-UEJump Radio Link. The coverage of DM-UE is limited, can realize two by multi-hop modeDM-UE communicates at a distance. DM-UE in the trunked communication system of TD-LTE technologyTo adopt SC-FDMA (Single-carrierFrequency-DivisionMultipleAccess,Single-carrier frequency division multiple access) send mode, can keep like this TD-LTE terminal transmitting chain baseIn this situation of not making an amendment, realize the intercommunication between UE.
In LTE system, by PDCCH (PhysicalDownlinkControlChannel,Physical downlink control channel) transmit Downlink Control Information be used for dispatching PDSCH (PhysicalDownlinkSharedChannel, Physical Downlink Shared Channel) and PUSCH (PhysicalUplinkSharedChannel, Physical Uplink Shared Channel) transmit. At LTERel-11In introduced ePDCCH (EnhancedPhysicalDownlinkControlChannel, strengthenPhysical downlink control channel), ePDCCH adopts mode and the PDSCH of frequency division multiplexingMultiplexing. EPDCCH is by RRC (RadioResourceControl, Radio Resource controlAgreement) connect reconfiguration message and carry ePDCCH configuration information and indicate to certain UE.
Can realize two remote DM-UE by multi-hop mode communicates. DM-UESupport the group service under DMO pattern, support again multi-hop business. Consider DM-UEMay carry out transfer of data with multiple DM-UE, need to design under direct mode operation for certain simultaneouslyThe specific control information of DM-UE in DM-UE or certain cluster group, solve DM-UE asWhat finds the also dispatch of demodulation oneself, and indicates DM-UE correctly to receive by dispatchWith the problem that sends data. DM-UE need to determine the resource that control channel uses, by controllingChannel obtains dispatch.
