Specific embodiment

It will be appreciated by those skilled in the art that as described in the background art, using current NR agreement, will lead to UE and completed in switching Data are transmitted using default BWP in a very long time afterwards, message transmission rate is low.

The embodiment of the present invention provides a kind of cell switching method, firstly, UE receives the measuring control information that source cell is sent, The measuring control information includes the information for the BWP that each adjacent cell is supported, the BWP includes default BWP and business BWP, is made The default BWP and business BWP of each adjacent cell can be learnt before cell switching by obtaining the UE；Then it is controlled according to the measurement Information, the UE can measure the BWP that each adjacent cell is supported in advance before cell switches, to obtain measurement report, the survey Amount report at least may include the measurement result of the default BWP of each adjacent cell；Then, the UE sends institute to the source cell Measurement report is stated, so that the source cell can determine Target cell according to the measurement report；Later, the UE receives institute State the switching command of source cell transmission, the switching command includes the default BWP of the Target cell and small with the target The associated configuration information of business BWP in area, since before cell switching is completed, the UE is it has been found that the Target cell The associated configuration information of business BWP, thus the business BWP that the Target cell is supported can be measured in advance, it is described to obtain The measurement result of business BWP；Finally, the UE can be accessed according to the default BWP of the Target cell when carrying out cell switching The Target cell, and the business BWP actually used is determined according to the configuration information, to utilize the business actually used BWP continues data transmission.The cell handover scheme provided through the embodiment of the present invention, the UE can measure described in advance as far as possible The measurement result for the business BWP that Target cell is supported realizes that UE switches to Target cell from source cell, and small switching to target Data are quickly transmitted using business BWP behind area, to reduce UE to the greatest extent using the transmission time of default BWP, to improve business Transmission rate.

It is understandable to enable above-mentioned purpose of the invention, feature and beneficial effect to become apparent, with reference to the accompanying drawing to this The specific embodiment of invention is described in detail.

Fig. 1 is a kind of flow diagram of cell switching method of the embodiment of the present invention, and the cell switching method can be with Applied to user equipment side.Before UE switches to Target cell from source cell, UE and source cell (namely serving cell) are carried out Data transmission.Specifically, the UE passes through the default BWP in source cell first before UE and source cell carry out data transmission Upper initiating random access procedure is established wireless heterogeneous networks (Radio Resource Control, abbreviation RRC) connection, is entered Connection status；Then, the UE reports its bandwidth ability to the source cell in connected state；Then, small according to the source Area is the business BWP that the measuring control information for the business BWP that the UE is sent measures that the source cell is supported, it is small to obtain the source The measurement result for the business BWP that area supports；Later, the measurement result is reported into the source cell, the source cell according to The measurement result is the UE configuration service BWP；Finally, the UE transmits number with the source cell on the business BWP of configuration According to.

If the channel quality of the UE and the source cell, which deteriorates, to be deteriorated, and described in discovery in data transmission procedure UE and the channel quality of some adjacent cell are better than source cell, then the source cell can be using the adjacent cell as Target cell, and incites somebody to action The UE switches to the Target cell.

Specifically, as shown in Figure 1, in the present embodiment, the cell switching method may include steps of:

Step S101: receiving the measuring control information that source cell is sent, and the measuring control information includes each adjacent cell The information of the BWP of support, the BWP include default BWP and business BWP；

Step S102: measuring the BWP of each adjacent cell according to the measuring control information, described to obtain measurement report Measurement report includes at least the measurement result of the default BWP of each adjacent cell；

The step source cell S103: Xiang Suoshu sends the measurement report, so that the source cell is reported according to the measurement It accuses and determines Target cell；

Step S104: receiving the switching command that the source cell is sent, and the switching command includes the Target cell Default BWP and configuration information associated with the business BWP of the Target cell；

Step S105: the Target cell is accessed according to the default BWP of the Target cell, and according to the configuration information It determines the business BWP actually used, is transmitted with continuing business using the business BWP actually used.

More specifically, in step s101, the UE can receive the source cell from source cell and be sent to institute The measuring control information of UE is stated, the measuring control information may include what each adjacent cell adjacent with the source cell was supported The information of BWP, the BWP information may include default default BWP that BWP and business BWP namely each adjacent cell are supported and The time-frequency location information of business BWP.

Further, in step s 102, the UE can be according to the network measure control information received respectively to every The BWP that a adjacent cell is supported is measured, namely carries out the measurement of BWP rank, to obtain measurement report.The measurement report is extremely It less may include the measurement result for the default BWP that each adjacent cell is supported.Specifically, since source cell may be different from adjacent cell Step, thus, source cell can be before sending measuring control information, and it includes synchronization signal block (synchronize that Xiang Suoshu UE, which is sent, Signal block) each adjacent cell support default BWP.If the UE receives the letter of the default BWP of adjacent cell support Breath, the UE can preferentially measure each default BWP, both complete the Network Synchronization of the UE Yu each adjacent cell, get back each The measurement result of a default BWP.After Network Synchronization, the UE can continue to measure the business BWP that each adjacent cell is supported.

Further, in step s 103, the measurement report can be sent to the source cell by the UE.The source Cell can determine Target cell according to the measurement result for each adjacent cell that the measurement report includes, to cut the UE Shift to the Target cell.Wherein, the measurement report can be by existing long term evolution (Long Term Evolution, abbreviation LTE) technology reports to network (namely source cell).LTE technology can send measurement report and event touching using periodic mechanism Hair mechanism sends measurement report.Under normal circumstances, measurement report is that UE based on event trigger mechanism reports to network.Once surveying Amount result meets trigger conditions (for example, the signal strength of adjacent cell is higher than pre-determined threshold and source cell lower than pre- gating Limit), UE reporting measurement reports will be triggered, so that network determines Target cell according to the measurement report.

Further, in step S104, the UE can be received from the source cell and be switched to the Target cell Switching command.The switching command may include the default BWP of the Target cell, so that the UE can be based on the default BWP accesses Target cell.The switching command can also include associated with the business BWP of the Target cell with confidence Breath.The configuration information facilitates the UE and obtains the business BWP actually used, to switch to the transmission of the business after Target cell It prepares.It should be noted that in embodiments of the present invention, it is described as the default BWP of Target cell described known to the UE Switching command can not include the default BWP.

Further, in step s105, the UE can be random by initiating on the default BWP of the Target cell Access procedure accesses the Target cell.Wherein, the random access procedure can use the access module of non conflicting, can also be with Using the access module of conflict.Once being determined used by switching after the completion according to the associated configuration information of the business BWP Business BWP, so that it may so that the UE can continue to transmit data based on the business BWP after the completion of switching.But in business BWP On carry out data transmission before, need Target cell that the active information of the business BWP is sent to the UE.The active information UE can be notified by Downlink Control Information (Downlink Control Information, abbreviation DCI).The DCI information It can be placed in random access response or contention resolution message according to the access module of the UE.If the access module is The access module of non conflicting then activates the DCI packet of the business BWP contained in accidental access response message；If access Mode is the access module of conflict, then activates the DCI packet of the business BWP contained in contention resolution message.

Further, if the UE, which is sent to the measurement report of the source cell, defaults BWP's for each adjacent cell Measurement result, the business BWP not comprising each adjacent cell, then the associated configuration information of business BWP may include described The measuring control information of the default BWP and each business BWP of Target cell.

In one non-limiting embodiment, with reference to Fig. 2, if the UE receives the measurement control of each business BWP Information, then step S105 shown in FIG. 1 may comprise steps of:

Step S1051: after receiving the switching command that the source cell is sent, according to the measurement control of each business BWP Information processed measures, to obtain the measurement result of each business BWP；

Step S1052: the measurement result of each business BWP is sent to the Target cell；

Step S1053: the business BWP of the practical use of the Target cell configuration, the business actually used are received BWP is that the Target cell is determined according to the measurement result of each business BWP.

Specifically, the UE receives switching command from the source cell, if the switching command in step S1051 In each business BWP comprising Target cell measuring control information, then after receiving the switching command, the UE is by base Each business BWP of the measurement Target cell is attempted in the measurement gap of source cell configuration, to obtain each business BWP Measurement result.

Further, if the UE just completes industry before sending switching and completing (handover complete) message The measurement of business BWP, then can carry the measurement result of each business BWP in handoff completion message.It is described in step S1052 The measurement result of obtained each business BWP is placed in handoff completion message by UE, and is sent to the Target cell.

Further, in step S1053, if the UE carries the Target cell in handoff completion message The measurement result of whole business BWP, then after the Target cell described in the UE access, the Target cell can be according to the survey Amount result is that the UE configures the business BWP actually used.Actually adopting for its configuration is received from the Target cell in the UE After business BWP, the UE can be with the Target cell in the business BWP transmitting data.

It further, may be due to when measurement gap be inadequate or measurement it will be appreciated by those skilled in the art that in handoff procedure Between the reasons such as deficiency, the UE may cannot get the measurement result for whole business BWP that the Target cell is supported.In this condition Under, if the UE carries the measurement result of partial service BWP in the handoff completion message, the UE access extremely After the Target cell, the Target cell can be the UE allocating and measuring gap, and improve the industry for not obtaining measurement result Be engaged in the measurement priority of BWP so that the UE preferentially measure described in do not obtain the business BWP of measurement result, and surveyed Report measurement results after amount result, so that the Target cell is quickly the business BWP that the UE determines transmission data.It is worth one Be mentioned that, existing LTE technology can after meeting event trigger threshold reporting measurement reports again, and the embodiment of the present invention Can be different from the measurement reporting schemes of existing LTE, such as the survey of the UE measurement business BWP for not obtaining measurement result Amount result, can be after completing to the measurement of whole business BWP without meeting event trigger threshold or considering measured value size Report correlation measurements.

According to above content, if the UE is receiving the switching command to the period for sending handoff completion message It is interior, fail to obtain the measurement result for the business BWP that the Target cell is supported, then the UE can be to access to the target small Qu Hou preferentially measures each business BWP that the Target cell is supported, and is the UE distribution business after obtaining measurement result BWP, so that the UE can be with the Target cell in the business BWP transmitting data.

Further, if the default BWP supported each adjacent cell and industry is completed in the UE before initiating a handover Be engaged in BWP measurement namely the UE be sent to the source cell measurement report include each adjacent cell default BWP and business The measurement result of BWP, then the source cell is gone after determining Target cell, it is true according to the measurement report by the Target cell Surely the business BWP that supports the UE to carry out data transmission simultaneously carries the Target cell by switching command by the source cell The default BWP and business BWP actually used is sent to the UE.Namely the business BWP phase involved in step S104 Associated configuration information includes the default BWP and the business BWP actually used of the Target cell.

Fig. 3 is the flow diagram of another cell switching method of the embodiment of the present invention.Wherein, the present embodiment is from network Side illustrates the operating process of the cell switching method.Specifically, as shown in figure 3, the cell switching method of the embodiment of the present invention It may comprise steps of:

Step S301: measuring control information is sent to user equipment, the measuring control information includes each adjacent cell branch The information of the BWP held, the BWP include default BWP and business BWP；

Step S302: receiving the measurement report of the BWP of each adjacent cell from the user equipment, according to the measurement report It determines Target cell, and the measurement report is sent to the Target cell, it is small that the measurement report includes at least each neighbour The measurement result of the default BWP in area；

Step S303: the default BWP and configuration information associated with business BWP of the Target cell configuration are received；

S304: Xiang Suoshu user equipment of step sends switching command, and the switching command includes the silent of the Target cell BWP and configuration information associated with the business BWP of the Target cell are recognized, so that the user equipment is according to the mesh The default BWP for marking cell accesses the Target cell, and the business BWP actually used is determined according to the configuration information.

Specifically, in step S301, source cell to user equipment (namely UE) send measuring control information so that The UE can measure the information for the BWP that each adjacent cell is supported on the measurement gap that the source cell configures.The BWP can To include default BWP and business BWP.

Further, the UE can complete measurement simultaneously after the time-frequency location information for learning default BWP and business BWP Upload measurement report.In step s 302, the source cell can receive the measurement report of the BWP of each adjacent cell from the UE In learn the measurement result of each adjacent cell.The source cell can determine Target cell according to the measurement result.It considers The source cell may be nonsynchronous with its adjacent cell, thus the source cell can require the UE small in each neighbour of completion The measurement of business BWP is carried out after the measurement of the default BWP in area, again to complete the Network Synchronization of the UE Yu each adjacent cell.Into One step, to realize Network Synchronization, the source cell can also be before sending measuring control information, and Xiang Suoshu UE is sent comprising same Walk the default BWP that each adjacent cell of block (synchronize signal block) is supported.

It further, can be by the measurement report (for example, the measurement after the source cell determines Target cell Report includes measurement result associated with the Target cell) it is sent to the Target cell, complete the Target cell Allocating default BWP and configuration information associated with the business BWP of the Target cell.It should be noted that in the present invention In embodiment, when network (such as source cell or Target cell) determines the default BWP of the Target cell known to the UE, institute The default BWP can not included by stating switching command.
