User equipment can establish Data Radio Bearer by configured portions of bandwidth and base station.User equipment has obtained All required arguments of configured portions of bandwidth, for example, the position of Physical Resource Block occupied by configured portions of bandwidth, has matched Set CORESET configuration in portions of bandwidth, PDSCH configuration, PUCCH configuration, PUSCH configuration, reference signal configuration, RACH configuration Deng.Specifically, configured portions of bandwidth can be the portions of bandwidth of initial activation.It should be noted that the configuration of a cell Parameter includes that the specific parameter configuration of cell (i.e. this partial parameters is configured by cell) and the specific parameter of portions of bandwidth are matched Set that (i.e. this partial parameters is configured according to BWP, and the parameter setting of difference BWP is different in the same cell, as PDSCH is configured Different configurations can be used in different BWP).Present invention is generally directed to the specific parameter configurations of portions of bandwidth.
Due to the business demand of user equipment and/or the ability of user equipment, base station needs new for user device configuration Portions of bandwidth namely portions of bandwidth to be configured.Portions of bandwidth to be configured is different from configured portions of bandwidth.Specifically, wait match The mark for setting portions of bandwidth is different from the mark of configured portions of bandwidth.For example, portions of bandwidth BWP2's to be configured is identified as 2, Configured portions of bandwidth BWP0's is identified as 0.
Furthermore, portions of bandwidth to be configured and configured portions of bandwidth can be the bandwidth portion in same serving cell Point.In cell handoff scenario, portions of bandwidth to be configured can be the portions of bandwidth in target serving district；Configured bandwidth portion Divide the portions of bandwidth that can be in former serving cell (serving cell before switching).
In the specific implementation of step S101, base station can be determined according to portions of bandwidth to be configured and configured portions of bandwidth The parameter to be updated of the user equipment.Specifically, base station can mark according to portions of bandwidth to be configured and configured band The mark of wide portion determines the parameter to be updated of the user equipment；It can also be according to the design parameter in portions of bandwidth to be configured Design parameter value in value and configured portions of bandwidth determines the parameter to be updated.
And then in step s 102, the parameter value of the parameter to be updated is sent to user equipment by base station, for described User equipment carries out parameter configuration according to the parameter value of the parameter to be updated.
Furthermore, base station can be incited somebody to action by wireless heterogeneous networks (Radio Resource Control, RRC) signaling The parameter value of the parameter to be updated is sent to user equipment.
Specifically, user equipment can save the parameter to be updated, so as to the activation of base station triggers user equipment to When configured bandwidth part, the parameter value of the parameter to be updated is can be used in user equipment.Alternatively, base station is described to more in transmission User equipment is triggered while new parameter and activates portions of bandwidth to be configured, then user equipment can directly use the ginseng to be updated Several parameter values.
It should be noted that user equipment be referred to using the detailed process of the parameter of portions of bandwidth it is in the prior art Associated description, details are not described herein again.
The portions of bandwidth to be configured that the embodiment of the present invention passes through the configured portions of bandwidth of user equipment and needs to configure, It determines the specific parameter value for needing to be sent to user equipment, avoids when needing to configure portions of bandwidth every time, it will be all The parameter value of portions of bandwidth is all sent to user equipment, saves signaling overheads；And then improve user equipment and base station it Between communication efficiency.
In a preferred embodiment of the invention, the serving cell is main plot；Or the serving cell be main plot and Secondary cell.
In the present embodiment, user equipment is generally configured with a serving cell i.e. main plot.Under the scene of carrier wave polymerization, use The serving cell of family equipment has main plot and at least one secondary cell；In this case, it is small that master can be respectively configured in base station The portions of bandwidth to be configured of the portions of bandwidth and secondary cell to be configured in area.In other words, base station can be according to the to be configured of main plot Portions of bandwidth and the configured portions of bandwidth of main plot determine to be updated parameter of the user equipment on main plot；It base station can Determine the user equipment in secondary cell with the configured portions of bandwidth of portions of bandwidth and secondary cell to be configured according to secondary cell On parameter to be updated.
In a kind of specific embodiment of step S101 shown in Fig. 1, if the mark of the portions of bandwidth to be configured with The mark of all configured portions of bandwidth is different, then base station determines that the portions of bandwidth to be configured is newly-increased portions of bandwidth；Base It stands and determines that all parameters of the newly-increased portions of bandwidth are the parameter to be updated.Specifically, the mark of portions of bandwidth can be The index (BWP Index) of portions of bandwidth or the identity (BWP IDentity) of portions of bandwidth.For example, portions of bandwidth to be configured Be identified as Index 1, configured portions of bandwidth is identified as Index 2.
In the present embodiment, for increasing portions of bandwidth newly, since its mark is different from the mark of all configured portions of bandwidth, Therefore any information of newly-increased portions of bandwidth is not saved in user equipment side.At this point, base station is needed the institute of newly-increased portions of bandwidth There is parameter to be sent to user equipment, therefore base station is using all parameters of newly-increased portions of bandwidth as the parameter to be updated.
In another specific embodiment of step S101 shown in Fig. 1, if existed in the configured portions of bandwidth Portions of bandwidth identical with the mark of the portions of bandwidth to be configured, it is determined that the portions of bandwidth is portions of bandwidth to be modified； Determine that parameter different from the portions of bandwidth parameter value to be modified in the portions of bandwidth to be configured is the parameter to be updated.
In the present embodiment, for portions of bandwidth to be modified, since its mark is present in configured portions of bandwidth, User equipment side preserves the parameter of portions of bandwidth to be modified.At this point, base station needs to modify in the parameter of portions of bandwidth to be modified The parameter value of partial parameters.Namely the partial parameters for needing to modify in portions of bandwidth to be modified are the parameter to be updated.
And then base station only needs the parameter value by the parameter to be updated to be sent to user equipment, in portions of bandwidth to be modified not The parameter value for the parameter for needing to modify then is never sent to user equipment.User equipment then only needs to receive the parameter to be updated Parameter value；For the other parameters in portions of bandwidth to be modified in addition to parameter to be updated, user equipment can be continued to use The parameter value of preservation.
In another preferred embodiment of the present invention, step S101 shown in Fig. 1 be may comprise steps of: the user is set It is standby when being switched to target serving district from former serving cell, according to the portions of bandwidth to be configured and benchmark of the target serving district Portions of bandwidth determines the parameter to be updated, and the reference bandwidth part is the configured portions of bandwidth of the former serving cell At least partially.
The Parameter Configuration process of the portions of bandwidth under cell handoff scenario is illustrated in the present embodiment.
User equipment has two kinds of serving cells, serving cell and switching before switching when user equipment carries out cell switching Serving cell afterwards, namely former serving cell and target serving district.For different cells, the portions of bandwidth having can also It can be different.In order to reduce configuration target serving district portions of bandwidth parameter when signaling overheads, base station can determine former clothes At least part of the configured portions of bandwidth for cell of being engaged in is benchmark portions of bandwidth；Band to be configured in configuration target serving district When the parameter of wide portion, portions of bandwidth to be configured and reference bandwidth part determine the parameter to be updated.Furthermore, switch In the process, UE can have former main plot and former secondary cell configuration in former base station side；After the handover, target BS side can have mesh Main plot and the configuration of target secondary cell are marked, target BS can be according to the portions of bandwidth to be configured of target main plot and former main plot Configured portions of bandwidth determine to be updated parameter of the user equipment on target main plot；Target BS can be according to mesh The configured portions of bandwidth of the portions of bandwidth to be configured and former secondary cell of marking secondary cell determines that the user equipment is auxiliary small in target Parameter to be updated in area.Target BS and former base station may be the same or different.
It is understood that when target serving district has multiple portions of bandwidth to be configured, multiple portions of bandwidth to be configured Corresponding reference bandwidth part can be identical or different.
That is, if the mark of the mark of the portions of bandwidth to be configured of target serving district and reference bandwidth part not Together, it is determined that the portions of bandwidth to be configured of target serving district is newly-increased portions of bandwidth；Determine the institute of the newly-increased portions of bandwidth Having parameter is the parameter to be updated.
If there is bandwidth identical with the mark of portions of bandwidth to be configured of target serving district in reference bandwidth part Part, it is determined that the portions of bandwidth is portions of bandwidth to be modified；Determine in the portions of bandwidth to be configured of target serving district with The different parameter of the portions of bandwidth parameter value to be modified is the parameter to be updated.
Further, before determining the parameter to be updated, base station can choose the former serving cell for base station At least part of configured bandwidth part is as the reference bandwidth part；Base station sends the mark of the reference bandwidth part To the user equipment.Base station can merge the mark of the reference bandwidth part and parameter to be updated believes in same RRC It is sent in order.
In the present embodiment, the reference bandwidth some notifications user equipment that base station needs to be chosen, so that user equipment exists Parameter configuration can be carried out after receiving parameter to be updated.
Specifically, when parameter to be updated is all parameters of newly-increased portions of bandwidth, user equipment passes through comparison basis bandwidth The mark for the portions of bandwidth that partial mark and base station are sent determines that parameter to be updated is all parameters of newly-increased portions of bandwidth, Then user equipment can save all parameters of newly-increased portions of bandwidth.
When parameter to be updated is the parameter of portions of bandwidth to be modified, user equipment passes through the mark of comparison basis portions of bandwidth The mark of the portions of bandwidth sent with base station determines that parameter to be updated is the parameter of portions of bandwidth to be modified, then user equipment is protected Deposit the parameter of the portions of bandwidth to be modified；For other ginsengs in portions of bandwidth to be modified in addition to the parameter to be updated Number can then continue to use the parameter value of portions of bandwidth to be modified in the former serving cell saved.
Closer, base station can choose in the configured portions of bandwidth of the former serving cell with the destination service The identical portions of bandwidth of mark of the portions of bandwidth to be configured of cell, using as the reference bandwidth part.
In order to realize the convenience of base station side and user equipment side parameter configuration, base station can choose former serving cell Portions of bandwidth identical with the mark of portions of bandwidth to be configured of the target serving district in configured bandwidth part, using as institute State reference bandwidth part.For example, base station can choose band of the portions of bandwidth BWP0 of former serving cell as target serving district The reference bandwidth part of wide portion BWP0；Base station will compare when configuring the parameter of portions of bandwidth BWP0 of target serving district The values of parameters is determined to more in the portions of bandwidth BWP0 of the portions of bandwidth BWP0 of target serving district and former serving cell New parameter.
Closer, when the number of the portions of bandwidth to be configured of the target serving district is multiple, the reference tape Wide portion includes multiple configured portions of bandwidth identical with the mark of multiple portions of bandwidth to be configured.
For example, the portions of bandwidth to be configured of target serving district is BWP0, BWP1 and BWP2；Former serving cell it is configured Portions of bandwidth is respectively BWP0, BWP1 and BWP2, then base station can choose the portions of bandwidth BWP0 of former serving cell as mesh Mark the reference bandwidth part of the portions of bandwidth BWP0 of serving cell；The portions of bandwidth BWP1 of former serving cell is small as destination service The reference bandwidth part of the portions of bandwidth BWP1 in area；Bandwidth of the portions of bandwidth BWP2 of former serving cell as target serving district The reference bandwidth part of part BWP2.
Further, when portions of bandwidth is not configured in the target serving district, the band to be configured of the target serving district The parameter of wide portion is the parameter of the target serving district.That is, when portions of bandwidth is not configured in target serving district, institute The parameter for stating the portions of bandwidth to be configured of target serving district is the position of Physical Resource Block occupied by the target serving district Set and CORESET therein configuration, PDSCH configuration, PUCCH configuration, PUSCH configuration, reference signal configuration, RACH configuration Deng.In this case, the reference bandwidth part is selected from the benchmark of initial portions of bandwidth, pre-set bandwidths part or base station instruction Portions of bandwidth.
