It is indicated above, the prior art, when 5G terminal in communication system equipment carries out the cell switching of low delay, it is unclear that Need to carry out the cell switching or the switching of common cell of low delay, thus be unable to arranged rational uplink receiving link and Downlink transmission link.It is described in detail below with reference to Fig. 1.

In LTE communication system, the antenna configuration of terminal device (for example, UE) is 1T2R, it is, the terminal device Default configuration is 1 transmission link of uplink, 2 receives link of downlink.The terminal device can carry out common when carrying out cell switching Switching.The terminal device needs elder generation and source base station to interrupt data communication, may then pass through multi-upstream access mistake when cell switches Journey and target BS establish data link.In common handoff procedure, there can be switch data interruption.

The cell switching (for example, cell switching of 0ms delay) of low delay can be used to indicate that the terminal device in cell It when switching, needs before interrupting data communication with source base station, first establishes data link with target BS, and carry out data communication, Then data communication just is interrupted with source base station.In the cell switch process of low delay, terminal device can guarantee while and source Base station and target BS carry out data communication, and terminal device and source base station do not have the interruption of data communication, low delay may be implemented Cell switching.

In 5G NR communication system, for it is certain it is specific match frequency range, standard has been known together terminal device (for example, UE) Antenna configuration can be 2 transmission link of uplink, 4 receives link of downlink.

It therefore,, can when terminal device (for example, UE) can carry out the cell switching of low delay in 5G NR communication system To communicate a part of downlink reception link with source base station, a part of downlink reception link can be switched and communicated with target BS； Meanwhile can communicate a part of uplink receiving link with source base station, a part of uplink receiving link and target base can be switched It stands communication.

Terminal device (for example, UE) cell switching flow for carrying out 0ms is described in detail below with reference to Fig. 1.

Fig. 1 is the schematic flow chart that 0ms hand off signaling is carried out applied to the UE of the embodiment of the present application, and the step of Fig. 1 wraps Step 110-180 is included, these steps are described in detail below.Step 110:UE receives source base station (source node) hair The measurement control (measurement control) sent.

Source base station can need to issue different types of measurement task to UE using mobile management algorithm according to different, And can configure in message in RRC and be configured to UE sending measuring, RRC connection reconfiguration can be passed through The meas config cell carried in message is configured to UE sending measuring.Meas config cell can indicate that UE is measured Object, the standard of measurement report, the format of measurement report, the interval of measurement etc..

Step 115, UE sends measurement report (measurement report) to source base station.

UE can measure configuration at the RRC agreement end of UE according to the measuring configuration message that source base station issues, and execute In measurement process, if UE discovery measurement environment meets event described in measurement control, it can pass through Measurement report is reported to source base station.

Before step 115, data communication can be carried out between UE and source base station, which can be used the close of source base station Key is encrypted.

Step 120, source base station switches over judgement (handover decision).Source base station is receiving UE transmission After measurement report, start to decide whether to need to issue switching command.Switching command is issued if necessary, the source The target BS that base station can be switched to needs sends switching request, and source base station is the new interface-free resources of UE application.

In step 125, source base station sends switching request (handover to target BS (target node) request)。

Source base station can send handover request to target BS, and UE access is agreed in request target base station.Wherein, It may include that UE needs the history of the reason of switching over, the contextual information of UE, UE to believe in handover request signaling Breath etc..

In step 130, target BS replys Handover Request Acknowledge (handover request ACK) to source base station.

Target BS is judged after the handover request for receiving source base station transmission, if target BS is same Meaning UE access, then reply handover request ACK to source base station.

Step 135, source base station issues RRC connection reconfiguration to UE and sets (RRC connection reconfiguration).

Source base station can (the new interface-free resources application after the handover request ACK for receiving target BS transmission Success), switching command can be issued to UE by RRC connection reconfiguration signaling, instruction UE initiation is cut Move work.

RRC connection reconfiguration signaling may include Target cell area in cell ID, carrier frequency, New UE mark etc..

Step 140, UE is synchronous with target BS, keeps connection (synchronize to target cell with source base station but keep connection with source cell)。

UE, can be according to switching after the RRC connection reconfiguration signaling for receiving source base station transmission Command cue switches a part of uplink transmission link and/or downlink reception link is synchronous with target BS completion, meanwhile, UE will be another A part of uplink transmission link and/or downlink reception link and source base station keep data link.

Before step 145, source base station can be by the data forwarding of UE to target BS.

Step 145, UE sends Physical Random Access Channel (physical random access to target BS Channel, PRACH).

UE can be by sending Physical Random Access Channel to initiate random access to target BS.

Step 150, target BS distributes uplink (uplink, UL) to UE.

Target BS is assigned with uplink resource after the random access request for receiving UE transmission, for UE.

Step 155, UE sends RRC connection reconfiguration to target BS and sets completion (RRC connection reconfiguration complete)。

UE sends RRC connection after accessing new cell (target BS), to target BS Reconfiguration complete prompts target BS UE to access target BS.

Step 160, UE distinguishes Packet Data Convergence Protocol (packet data convergence protocol, PDCP) Data packet is from source base station or target BS (distinguish PDCP packet from source or target cell)。

When UE carries out data communication with source base station and target BS at the same time, can distinguish PDCP data is from source base station Or target BS.

Before step 160, UE and source base station carry out data communication, and the key which can be used source base station is added It is close；UE also carries out data communication with target BS simultaneously, and the key which can be used target BS is encrypted.

Step 165, UE separates (detch from source cell) from source cell.

UE can just be interrupted and source base station after realizing while carrying out data communication with source base station and target BS Between data link.

Step 170, source base station sends SN state transition (SN staus transter) to target BS.

UE carries out data link confirming with target BS, and after interrupting data link with source base station, source base station can be with The SN staus transter of UE is sent to target BS.

Step 175, target BS sends UE context release (UE context release) to source base station.

Target BS can send UE to source base station after receiving the SN staus transter of UE of source base station transmission Context release order.

Step 180, source base station release resource (release resource).

Source base station can discharge UE occupancy after the UE context release order for receiving target BS transmission Resource.

The 0ms switching flow in 1 can be seen that terminal device (for example, UE) and receive making for source base station transmission from the graph When carrying out upper transmission with single uplink.UE can separate a part of uplink transmitting link at this time and target BS carries out data-link It connects, but for UE, it is not clear that upper transmission or source base are carried out using single uplink because channel characteristics are dispatched Wish that UE can use another part uplink and carry out data link (that is, the cell for carrying out 0ms delay is cut with target BS in station It changes).

UE is in the switching flow that above-mentioned 0ms is delayed, if the antenna configuration of the UE is 2 transmission link of uplink, downlink 4 is connect Link is received, UE can separate a uplink transmission link and target BS establishes data link.But UE faces 4 downlink reception chains Do not know that separate 1 downlink reception link or 2 downlink reception links and target BS establishes data link in road.
