Description

Realize the method, system and device that subscriber equipment switches between network side node

Technical field

The present invention relates to communication technical field, relate in particular to a kind of method, system and device of realizing that subscriber equipment switches between network side node.

Background technology

At mobile cellular communication (the Long Term Evolution-Advanced of system of future generation, LTE-Advanced) can pass through coordinate multipoint (Coordinated Multi-point in system, COMP) the sending and receiving technology increases the covering of high data rate, thereby the throughput at raising network side node edge and the throughput that increases system, therefore, can only use COMP just can provide in some business of network edge.

Coordinate multipoint sending and receiving technology refers to a plurality of transfer points (different network side nodes) of separating on the geographical position, the collaborative participation a subscriber equipment (User Equipment, UE) transmission or receive data, as shown in Figure 1, in this Fig. 1, first network side gusset, second network side gusset and the 3rd network side node send data simultaneously to the UE that is positioned at the first network side gusset.

The COMP technology comprises up COMP and descending COMP.In up COMP, a plurality of network side nodes receive the upstream data that same UE sends simultaneously, and by certain technology, the data that receive are merged processing, and in descending COMP, a plurality of network side nodes send downlink data to same UE simultaneously.Descending COMP comprises again Combined Treatment (Joint Processing, JP) and coordinated scheduling (CooperatingScheduling, CS).Comprise again under the Combined Treatment mode: joint transmission and dynamic network side gusset are selected.

Wherein, in joint transmission, a plurality of network side nodes are a UE the transmission of data on PDSCH simultaneously, thereby can improve the quality that UE receives signal, and eliminate the interference from other UE.During the dynamic network side gusset is selected each constantly to only have a network side node be that UE sends data, this network side node can be in the COMP cooperation Dynamic Selection.Under the combined dispatching mode, the service network side gusset that sends the PDCCH control information for UE is dispatched UE, and carry out transfer of data with it, by the coordination of the resources such as time, frequency, power and space between each service network side gusset, avoid or reduce phase mutual interference between different UEs.

The network side node set that the COMP technology comprises has: COMP cooperation (COMP cooperatingset), COMP measuring set (COMP measurement set) and RRM measuring set (RadioResource Management measurement set).

Wherein, the COMP cooperation comprises: the set of the network side node that can carry out the COMP transmission that network is determined, this the set in network side node direct or indirect at Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH) upper and UE the transmission of data, but should gather whether transparent not yet definite for UE.Also comprise COMP transfer point (COMPtransmission point (s)) set in this COMP cooperation, comprise in this set sending the set of the network side node of data to UE by PDSCH, the network side node in this COMP transfer point set is a subset of the network side node in this COMP cooperation.When carrying out joint transmission, network side node in this COMP transfer point set is the network side node in this COMP cooperation, when carrying out the selection of dynamic network side gusset, a network side node in each subframe in employing COMP cooperation is as transfer point, can select the heterogeneous networks side gusset as transfer point in this COMP cooperation in different subframes, and when carrying out cooperative scheduling or cooperative beam figuration, network side node in this COMP transfer point set is the service network side gusset, for example Serving cell (Serving Cell).

The COMP measuring set comprises: need the UE reporting status information of channel, or the set of the network side node of reporting channel statistical information.Network side node in this COMP measuring set may be identical with the network side node in this COMP cooperation, and give the correct time on UE carries out, and UE can select to report the channel condition information of subnetwork side gusset in this COMP measuring set, or channel statistical information.

The RRM measuring set comprises: carry out the set for the network side node of RRM measurement.

Fig. 2 carries out a kind of implementation method of transfer of data for employing COMP technology in descending COMP,

The method comprises the following steps:

S201: the information of network side node in the RRM measuring set is notified in the base station to UE.For example, the sign of each network side node in this RRM measuring set.

Certainly, the base station also can replace with other the network side entity that data send or receive that can UE carry out, and for example Relay, or base station controls lower node, and the node under this Relay control etc.

S202:UE is according to the information of network side node in the RRM measuring set that receives, network side node in this set is measured, and report the measurement result of measured network side node to the base station, wherein measurement result comprises: Reference Signal Received Power (Reference Signal Received Power, RSPR) information, Reference Signal Received Quality (Reference Signal Received Quality, RSRQ) information etc.

S203: this base station configures the COMP measuring set of this UE based on the measurement result to each network side node that UE reports, and the information of the COMP measuring set that will configure notice UE.

S204:UE receives the information of this COMP measuring set of this base station transmission, and according to the information of each network side node in this COMP measuring set, obtain the channel condition information of network side node in this set, or channel statistical information, wherein this channel condition information or channel statistical information comprise: pre-coding matrix indication (Precoding Matrix Indicator, PMI) information, or channel quality indication (Channel QualityIndicator, CQI) information etc.And in the COMP measuring set that will measure, channel condition information or the channel statistical information of network side node reports the base station.

S205: channel condition information or the channel statistical information of network side node in this COMP measuring set that the base station reports according to UE, determine the COMP cooperation of UE, and according to carrying out type different in descending COMP or up COMP (joint transmission, the selection of dynamic network side gusset and combined dispatching etc.), determine that in this COMP cooperation corresponding COMP transfer point and this UE carry out the transmission of data.

some service needed adopts COMP just can transmit when the network side node edge, as the UE that uses the COMP transmission when being switched to the network side destination node by the network side source node, need to carry out step shown in Figure 2 owing to carrying out transfer of data by startup COMP technology in situation, therefore when UE switches to the network side destination node, it is that the UE that adopts the COMP technology to carry out transfer of data in the network side source node sends data that the network side destination node can not adopt the COMP technology immediately, thereby make the UE Transmission of the business that receives high-speed data, affect the data transmission quality of this UE.
