Description
Technical field
The present invention relates to the indicating means and terminal of control channel under field of communication technology more particularly to direct mode operation.
Background technology
Trunked mobile communication system is a kind of advanced mobile command dispatching system, more demanding in commander, scheduling feature
The departments such as enterprise, cause, industrial and mineral, oil field, farm, airport, public security and army all play huge effect.TD-LTE(Time
Division LongTerm Evolution, timesharing long term evolution) technology be new generation broadband mobile communication wireless access skill
Art is small, high with transmission rate height, propagation delay time compared with the wireless access technology of existing 2G, 3G mobile communication system
The features such as QoS (Quality of Service, service quality) ensures.In existing TD-LTE technologies, increase group service
Characteristic, realize TD-LTE wideband digital trunked communication systems be trunked communication system developing direction.Network-off direct-passing function is
A kind of essential basic function in trunked communication system.Therefore, it is realized in TD-LTE wideband digital trunked communication systems
Network-off direct-passing is very important.
DMO (Direct Mode Operation, direct mode operation) refers to directly logical between two or more terminals
Letter.Under direct mode operation, the communication between two or more terminals is without base station and forwarded.As UE (User
Equipment, user equipment) have left network coverage area after, display exceeds service area, and UE can select the work of direct mode operation
Make mode, equipment can also be automatically into direct mode operation.Fig. 1 shows the communication pattern schematic diagram of DMO, the DM-UE in DMO
It is carried out by direct mode air interface between (Direct Mode User Equipment, the user equipment under direct-passing mode)
Point-to-point or point-to-multipoint communication.The DM-UE that synchronous reference is provided in DMO is known as master control UE；The DM- synchronous with master control UE
UE is known as subordinate UE.
In the trunked communication system based on TD-LTE technologies, DM-UE is connected by air interface with other DM-UE, DM-
UE can detect other DM-UE in adjacent area, and establish multi-hop wireless link step by step, until find target DM-UE, and and mesh
Mark DM-UE establishes multi-hop wireless link.The coverage area of DM-UE is limited, and two can be realized at a distance by multi-hop mode
DM-UE communicated.DM-UE will use SC-FDMA (Single-carrier in the trunked communication system of TD-LTE technologies
Frequency-Division Multiple Access, single-carrier frequency division multiple access) sending method, TD-LTE can be kept in this way
In the case that terminal transmission link is not made an amendment substantially, the intercommunication between UE is realized.
In LTE system, pass through PDCCH (Physical Downlink Control Channel, physical down link
Control channel) Downlink Control Information is transmitted for dispatching PDSCH (Physical Downlink Shared Channel, physics
DSCH Downlink Shared Channel) and PUSCH (Physical uplink Shared Channel, Physical Uplink Shared Channel) passed
It is defeated.EPDCCH (Enhanced Physical Downlink Control Channel, enhancing are introduced in LTE Rel-11
Physical downlink control channel), ePDCCH by the way of frequency division multiplexing with PDSCH be multiplexed.EPDCCH is to pass through RRC
(Radio Resource Control, radio resource control) connection reconfiguration sets message and carries ePDCCH configuration informations to refer to
Show and gives some UE.
It can realize that two remote DM-UE are communicated by multi-hop mode.DM-UE will be supported under DMO patterns
Group service supports multi-hop business again.In view of DM-UE may carry out data transmission with multiple DM-UE simultaneously, need to design
For the specific control information of DM-UE in some DM-UE or some cluster group under direct mode operation, to solve how DM-UE finds
And the dispatch of oneself is demodulated, and indicate that DM-UE is properly received and the problem of transmission data by dispatch.DM-UE is needed
It determines the resource that control channel uses, dispatch is obtained by control channel.
