Description
Technical field
The present invention relates in wireless communication technique radio resource management method more particularly to a kind of transmission node information
Configuration method and report method and a kind of network side equipment and a kind of terminal device.
Background technology
In order to provide a user the various businesses content such as voice, grouped data, broadcast, cordless communication network is extensive
Deployment.In order to meet the growing communication quality of user and traffic rate demand, wireless communication technique (wireless network) is continuous
Ground evolution development.
Cordless communication network is from global system for mobile communications (Global System For Mobile
Communication, GSM)/general wireless packet service system (General Packet Radio Service, GPRS) the 2nd
In generation, the/the 2.5 third generation mobile communication network evolved to Universal Mobile Communication System (Universal Mobile
Telecommunications System, UMTS) third generation mobile communications network.And use effect to preferably improve frequency spectrum
Rate meets the wireless communication needs that user is skyrocketed through, third generation partner program (The 3rd Generation
Partnership Project, 3GPP) tissue proposes the 4th third-generation mobile communication technology on the basis of UMTS and " drills for a long time again
Into " (Long Term Evolution, LTE) and its further evolution technology " senior long term evolution " (Long Term
Evolution Advance, LTE-A).
Cordless communication network usually can support multiple access by shared system resource, in addition cordless communication network
Support the mobility of terminal device (User Equipment, UE).In view of this consideration, in order to efficiently use system resource simultaneously
Provide good service communication to the user, cordless communication network needs to carry out effective resource management.By taking LTE system as an example, drill
Into type base station (enhanced NodeB, eNB) based on to uplink reference signals measurement or based on UE to downlink reference signal
Measurement, quality of wireless channel can be obtained, and consider the management that other factors carry out radio resource, for example considered
Quality of wireless channel, service distribution, adjacent area load, hardware resource, operator policies etc. are attached mobility control
(Connection Mobility Control, CMC)；Consider quality of wireless channel and resource service condition carries out resource
It dispatches (Resource Scheduling, RS)；Consider quality of wireless channel, business load carries out interference coordination (Inter-
Cell Interference Coordination, ICIC) etc..Wherein, UE refers to that UE is measured to downlink reference signal measurement
The reference signal (Cell-specific reference signals, CRS) of cell-specific simultaneously gives eNB measurement feedback.
Simultaneously, it is contemplated that the fluctuation that physical layer measures introduces L3 filtering in high level in standard at present, utilizes historical measurement pair
The result of current measurement carries out centainly smooth, as shown in Figure 1.
In order to meet the performance indicator of LTE-A, 3GPP introduce multipoint cooperative (Coordinated Multi Point,
CoMP) transmission technology.The principle of CoMP technologies is to utilize the multiple eNB detached on geographical location, or the multiple transmission nodes of title
(Transmission Point, TP) simultaneously participates in the data transmission with the same UE.It can effectively improve using CoMP technologies
Community marginal user performance effectively inhibits inter-cell interference；Moreover, it is also possible to increase the covering of high data rate, to improve
The handling capacity of cell edge, further increases throughput of system.
When using CoMP technologies, in order to weigh the signal quality for the transmission node that these simultaneously participate in transmission,
3GPP introduce channel state information reference signals (Channel-State Information reference Signal,
CSI-RS).UE can will participate in the channel status of the transmission node of transmission in data transmission in the feedback information of data transmission
Information reference signal feeds back to network side, and network side will use this information to carry out dynamic dispatching.
As shown in Fig. 2, in CoMP usage scenarios, the transmission node number of transmission can be participated in commonly greater than UE while being made
Transmission node number, network side need transmission node of the selection for simultaneous transmission from numerous transmission nodes, therefore net
Network side needs to know the signal quality of all transmission nodes, that is, obtains the corresponding channel state information of all transmission nodes with reference to letter
Number.
