Device structure shown in Figure 2 does not constitute the restriction to terminal device, may include more more or less than illustrating Component, perhaps combine certain components or different component layouts.

The embodiment of the present invention provides a kind of bandwidth indicating means, is applied to communication system shown in FIG. 1, as shown in figure 3, institute State method the following steps are included:

101, the network equipment generates instruction information, and the instruction information includes the first field, and first field is for referring to Show BWP；The instruction information is used to indicate the terminal device and receives downlink data or Xiang Suoshu that the network equipment is sent The network equipment sends upstream data.

In the specific implementation, the control that the instruction information can be transmitted with the control signaling of dispatching uplink data or indicating downlink Signaling processed, such as: DCI.BWP can be divided into uplink BWP and downlink BWP, each BWP has a call number (index), uplink The call number of BWP and downlink BWP may be the same or different, and it is not limited in the embodiment of the present invention.Implement in the present invention In example, the first field can serve to indicate that the call number of BWP.Exemplary, the first field indicates call number X, and base station then can be with Indicate that call number is the BWP of X by sending instruction information to terminal device.

In the embodiment of the present invention, base station can indicate the call number of a BWP come instruction terminal equipment by the first field Activation deactivates a BWP, and then controls the BWP of terminal device activation.

It should be noted that the first field can be the resource allocation (resource allocation) in instruction information Field, resource collection (resource set) indication field, redundancy versions (redundant version, RV) field, transmitting function Rate control field and modulation with it is any one or more in coding strategy MCS field.

Further, if the first field is one or more of above-mentioned field, all or part of the first field is used for Indicate BWP.Exemplary, the first field is the resource allocation field of long 20 bits, it is assumed that has 4 uplink BWP and 4 downlink BWP Totally 8 BWP can use log₂ ⁸=3 bits indicate the call number of BWP, then 20 bits of resource allocation field can be used In 3 bits indicate the call number of BWP.

In some embodiments, if come using the existing field (such as: above-mentioned resource allocation field) in instruction information It indicates BWP, then indicates that information can also include the second field, the second field is used to indicate whether first field is used to indicate BWP.Exemplary, the second field can be 1 bit, when the state of the second field is " 0 ", indicate that the first field is to be not used in finger Show BWP, that is to say, that without using the call number of the first field instruction BWP, the first field is used only for indicating its script characterization Information, such as: resource allocation field is used only for the distribution condition of instruction frequency domain and/or time-domain resource.When the shape of the second field When state is " 1 ", indicate that the first field is to also can indicate that BWP.Certainly, contain representated by the state value " 0 " of the second field or " 1 " Justice is not limited only to implementation above mode, can also there is other implementations, for example, " 1 " indicates that the first field is not have to In instruction BWP, " 0 " indicates that the first field is to also can indicate that BWP.The embodiment of the present invention is not construed as limiting this.

Furthermore it is also possible to indicate whether to indicate using the first field of instruction information by indicating other features of information The index of BWP.It is exemplary, distinguish whether the first field is used to indicate using different search spaces (search space) The index of BWP.Indicating to indicate BWP using the first field if: the network equipment sends instruction information using search space A Index, when terminal device search space A receive the network equipment transmission instruction information, then can determine the first field use In the index of instruction BWP.

Alternatively, the network equipment uses the cyclic redundancy check (Cyclic in different mark scrambling DCI or DCI Redundancy Check, CRC) index whether the first field is used to indicate BWP is distinguished, such as: the network equipment uses some mark The CRC known in scrambling DCI or DCI then indicates that the first field is used to indicate the index of BWP, and exemplary, which can be RNTI。

Or the network equipment uses different cyclic redundancy checks, distinguishes whether the first field is used to indicate BWP's Index, the network equipment use cyclic redundancy check-A, then it represents that the first field is used to indicate the index of BWP.

In some embodiments, the first field can also be BWP indication field, i.e., increases one newly in instruction information specially It is used to indicate activation or deactivates the field of BWP, this field can serve to indicate that the call number of BWP.

In the specific implementation, no matter the first field is that have the PWP increased newly in field, or instruction information in instruction information to refer to Show field, the network equipment indicates that BWP can specifically include following four situation by the first instruction information and the first field:

First field is used to indicate uplink BWP, and the instruction information is also used to indicate the terminal device to institute It states the network equipment and sends upstream data.That is, the network equipment indicates uplink BWP by the DCI of dispatching uplink data.

Or, first field is used to indicate uplink BWP, and the instruction information is also used to indicate that the terminal device connects Receive the downlink data that the network equipment is sent；That is, the network equipment indicates uplink by the DCI of dispatching downlink data BWP。

Or, first field is used to indicate downlink BWP, and the instruction information be also used to indicate the terminal device to The network equipment sends upstream data.That is, the network equipment passes through the DCI indicating downlink BWP of dispatching uplink data.

Or, first field is used to indicate downlink BWP, and the instruction information is also used to indicate that the terminal device connects Receive the downlink data that the network equipment is sent.That is, the network equipment passes through the DCI indicating downlink of dispatching downlink data BWP。

102, the network equipment sends the instruction information to the terminal device.

In the specific implementation, the network equipment can send the finger to the terminal device by the currently active downlink BWP Show information.Wherein, the currently active downlink BWP can be the downlink BWP that terminal device receives the instruction information.

103, the terminal device receives the instruction information, activates or deactivate the BWP of the first field instruction.

Specifically, the terminal device can also receive what the network equipment was sent by the currently active downlink BWP Indicate information.

It should be noted that the multiple downlink BWP of the network equipment typically terminal equipment configuration and multiple uplinks BWP, and only terminal device is allowed to activate an a downlink BWP and uplink BWP.In this scenario, the first field can indicate Activate a BWP.Specifically, the network equipment can indicate the call number of a BWP by the first field in instruction information, refer to Show that terminal deactivates the currently active BWP, the BWP which is indicated is activated.It should be noted that " current to swash here BWP " living can be the currently active downlink BWP, i.e. terminal device receives the downlink BWP for indicating information, can also currently swash Uplink BWP living.I.e. terminal device before step 101 for the last time transmit upstream data uplink BWP.If indicating information The instruction of the first field be a uplink BWP, terminal then deactivates the currently active uplink BWP, the first field of activation refers to The uplink BWP shown.If that indicate the first field instruction of information is a downlink BWP, by the currently active downlink if terminal BWP is deactivated, the downlink BWP of activation the first field instruction.

Under second of scene, terminal device is allowed to activate multiple downlink BWP and multiple uplink BWP.At this point, if instruction letter Breath instruction is uplink BWP, then terminal device can then change the state of the uplink BWP of instruction information instruction.Specifically, such as For fruit before receiving the instruction information, the uplink BWP of instruction information instruction is state of activation, then terminal receives instruction letter The uplink BWP of instruction information instruction is then deactivated after breath.If before receiving the instruction information, instruction information instruction Uplink BWP is deactivation status, then terminal receives the uplink BWP for then activating the instruction information to indicate after the instruction information.

In addition, in a second possible scenario, if that instruction information instruction is downlink BWP, and downlink BWP is terminal device The downlink BWP of the instruction information is received, then terminal device does not execute activation after receiving the instruction information or deactivates the behaviour of BWP Make.If that indicate information instruction is downlink BWP, and downlink BWP is not the downlink that terminal device receives the instruction information BWP, then terminal device can then change the state of the downlink BWP of instruction information instruction.Specifically, if receiving the instruction Before information, the downlink BWP of instruction information instruction is state of activation, then terminal then deactivates this after receiving the instruction information Indicate the downlink BWP of information instruction.If the downlink BWP of instruction information instruction is to deactivate before receiving the instruction information State living, then terminal receives the downlink BWP for then activating the instruction information to indicate after the instruction information.

Exemplary, before terminal device receives instruction information, the call number of the downlink BWP of terminal device activation is 4,6, and Terminal receives the instruction information by the downlink BWP that call number is 6.If indicate information instruction is the downlink that call number is 6 BWP, then terminal device does not execute activation or deactivated operation.

If instruction information instruction be not call number be 6 downlink BWP, as call number be 7 downlink BWP, then eventually It is 7 downlink BWP that end equipment, which activates quotation marks,.Alternatively, terminal is set if that indicate information instruction is the downlink BWP that call number is 4 It is standby then deactivate call number be 4 downlink BWP.

In the specific implementation, after terminal device receives instruction information, parsing instruction information determines instruction information instruction The index of BWP.The downlink that the network equipment is sent can be received according to the instruction information first on the currently active downlink BWP Data first send upstream data to the network equipment on the currently active uplink BWP, then switch to instruction letter again It ceases and carries out subsequent data transmission on the BWP of instruction.

It is exemplary, it is assumed that the instruction of the first field is a downlink BWP, the network equipment can before step 103 or it Afterwards, downlink data is sent on the downlink BWP (i.e. the currently active downlink BWP) for sending the first instruction information, terminal is set It is standby to receive downlink data on downlink BWP.Terminal device switches to the downlink BWP of the activation of the first field instruction again later On.

Assuming that the first field instruction be a uplink BWP, then terminal device can before or after step 103, It is sent using the uplink BWP (i.e. the currently active BWP) that last time before step 101 sends upstream data to the network equipment Row data.Terminal device is switched to again on the uplink BWP of the activation of the first field instruction later.

Certainly, terminal device can also first switch to the BWP of instruction information instruction, then exist after parsing indicates information On new BWP, the downlink data of network equipment transmission is received according to the instruction information or sends upstream data to the network equipment.

It is exemplary, it is assumed that the instruction of the first field is downlink BWP, and after step 103, the network equipment is in first field On the downlink BWP for indicating activation, downlink data is sent, terminal device connects on the downlink BWP of first field instruction activation Receive the downlink data that the network equipment is sent.

Assuming that the instruction of the first field is uplink BWP, after step 103, terminal device swashs in first field instruction On uplink BWP living, to the upstream data of network equipment transmission.

It should be noted that if the call number of uplink BWP and downlink BWP are different, that is, a call number can Uniquely to indicate uplink BWP or downlink BWP.Under this scene, the first field can uniquely indicate uplink BWP or one A downlink BWP.Exemplary, there are four uplink BWP for configuration, and call number is respectively 0~3, while there are four downlink BWP, ropes for configuration Quotation marks are respectively 4~7, can indicate call number with 3 bits, some state value of this 3 bit uniquely corresponds to a call number, i.e., A unique corresponding uplink BWP or downlink BWP.Such as: the state value of 3 bits is the BWP that " 000 " instruction call number is 0, is one Uplink BWP, the state value of 3 bits are the BWP that " 110 " instruction call number is 6, are a downlink BWP.Wherein, 3 bits can be The whole of first field, i.e. the first field are BWP indication field, and 3 bits are also possible to some or all of first field, i.e., the One field is to indicate the existing field of information, indicates BWP using these fields.

If the call number of uplink BWP and downlink BWP are all identical or part is identical, that is, a call number is possible to Indicate a uplink BWP and a downlink BWP.Under this scene, the first field cannot uniquely indicate a uplink BWP or one Downlink BWP.It needs to combine the first indication field at this time and indicates other features of information to determine the instruction of instruction information actually It is uplink BWP or row BWP.Exemplary, there are four uplink BWP for configuration, and call number is respectively 0~3, while configuring there are four under Row BWP, call number are respectively 0~3, can indicate call number with 2 bits, the corresponding index of some state value of this 2 bit Number, i.e., the call number cannot distinguish between an a corresponding uplink BWP or corresponding downlink BWP.Such as: the state value of 2 bits is " 00 " indicates that call number is 0 BWP, can be the uplink BWP that call number is 0, is also possible to call number under one of 0 Row BWP.That is, under this scene the first field indicate be two different types of BWP, it is also necessary to combine the first instruction Other features of information to indicate the type of BWP to terminal device, i.e. the BWP of the first field instruction is uplink BWP or downlink BWP.That is, the instruction information may be used to indicate that the type of BWP.

Further, the network equipment can indicate the type of BWP by following three kinds of modes, specifically:

The first, increase BWP type indicating bit in instruction information to indicate the type of BWP, the length of BWP type indicating bit It can be 1 bit.

When the BWP type indicating bit is the first numerical value, the instruction information is used to indicate uplink BWP；As the BWP When type indicating bit is second value, the instruction information is used to indicate downlink BWP.

Exemplary, BWP type indicating bit is " 0 ", and that illustrate the instruction of the first field is uplink BWP；BWP type indicating bit is " 1 ", that illustrate the instruction of the first field is downlink BWP.Alternatively, BWP type indicating bit be " 1 ", illustrate the first field indicate be Uplink BWP；BWP type indicating bit is " 0 ", and that illustrate the instruction of the first field is downlink BWP.Certainly, the shape of BWP type indicating bit Meaning representated by state value " 0 " or " 1 " is not limited only to implementation above mode, can also there is other implementations, and the present invention is real It applies example and this is not construed as limiting.

The second, the type by indicating the different scrambling mode of instruction information BWP.

When the instruction information is scrambled using first identifier, the instruction information is used to indicate uplink BWP；Or, working as institute When stating instruction information using second identifier scrambling, the instruction information is used to indicate downlink BWP.

It should be noted that perhaps second identifier can scramble or right the DCI of instruction information the first identifier Indicate that the CRC in the DCI of information is scrambled, the embodiment of the present invention is not construed as limiting this.

Certainly, the network equipment can also indicate a BWP type by some specific mark, such as: (being represented using A One mark) to instruction information scrambling, then that the instruction information instruction is uplink BWP.After terminal device receives instruction information, By the scrambling mode of identification instruction information, the type of BWP indicated by instruction information can be determined.

Exemplary, first identifier and second identifier can be the first radio network temporary identifier (radio network Temporary identifier, RNTI) and the 2nd RNTI, it can also be other identifier, the embodiment of the present invention does not limit this It is fixed.

In the specific implementation, the network equipment can be by referring to wireless heterogeneous networks (radio resource control, RRC) Signaling can also notify to mark by broadcast signaling to the corresponding relationship of terminal device notice mark and BWP type to terminal device Know the corresponding relationship with BWP type, naturally it is also possible to the corresponding relationship of regulation mark and BWP type in consensus standard.In addition, When identifying the corresponding relationship with BWP type to terminal device notice, a mark and an offset, terminal device can be notified Another mark can be determined according to a mark and an offset.Exemplary, notify to terminal device: mark A is corresponding Uplink BWP and offset, terminal device can determine another mark B according to mark A and offset, and then determine mark B corresponds to downlink BWP.

Third, the type that BWP is indicated by different search spaces.

So-called search space (search space) refers to multiple Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH) set, pair terminal device can carry out blind Detecting in search space, i.e., Various possible PDCCH carry out blind decoding.

When the network equipment is when the first search space sends the instruction information, the instruction information is used to indicate Row BWP；Or, the instruction information is used to indicate when the network equipment is when the second search space sends the instruction information Downlink BWP.

Certainly, the network equipment can also indicate a BWP type by some specific search space, such as: utilize B (representing a search space) sends instruction information, then the instruction information indicates uplink BWP.If terminal device is to search Space B carries out blind Detecting, has decoded the instruction information of network equipment transmission, then can determine the class of instruction information instruction BWP Type is uplink BWP.

In the embodiment of the present invention, different user equipment specific search space (user equipment can be used Special search space, UESS) come distinguish instruction information the first field instruction be uplink BWP or downlink BWP. It is exemplary, if the network equipment indicates uplink BWP, instruction information is sent using the first UESS, if under network equipment instruction Row BWP then sends instruction information using the 2nd UESS.Terminal device carries out blind Detecting in the first UESS and decodes the instruction letter Breath, it is determined that the network equipment indicates that uplink BWP, terminal device carry out blind Detecting in the 2nd UESS and decode the instruction information, Then determine network equipment indicating downlink BWP.Further, it is possible to determine indicated BWP's according to the first field of instruction information Call number.

In the specific implementation, the network equipment can be by referring to wireless heterogeneous networks (radio resource control, RRC) Signaling, can also be logical to terminal device by broadcast signaling to the corresponding relationship of terminal device notice search space and BWP type Know the corresponding relationship of search space and BWP type, naturally it is also possible to pair of search space and BWP type is provided in consensus standard It should be related to.In addition, can notify a search space when notifying the corresponding relationship of search space and BWP type to terminal device With an offset, terminal device can determine another search space according to a search space and an offset.Show Example, notify to terminal device: search space A corresponds to uplink BWP and offset, and terminal device can be according to search space A Another search space B is determined with offset, and then determines that search space B corresponds to downlink BWP.

It should be noted that only allowing the field of one downlink BWP and a uplink BWP of terminal device activation in synchronization Under scape, if the instruction of the first field is the currently active downlink BWP of terminal device or the currently active uplink of terminal device BWP, terminal device then ignore the instruction of the first field and do not execute activation or deactivated operation after receiving instruction information, after It is continuous still to receive the downlink data that the network equipment is sent in the currently active downlink BWP, or, in the currently active uplink BWP to net Network equipment sends upstream data.

In bandwidth indicating means provided in an embodiment of the present invention, the network equipment generates instruction information, and instruction information is for referring to Show that terminal device sends upstream data to the network equipment or receives the downlink data that the network equipment is sent.Further, information is indicated The first field can indicate another BWP (can be uplink BWP or downlink BWP).Terminal receives the finger that the network equipment is sent After showing information, the currently active BWP can be deactivated, the BWP of activation the first field instruction refers to so that UE is transformed into this Show and receives downlink data or transmission upstream data on the BWP of information instruction.Alternatively, terminal device can also be the currently active The BWP of the first field instruction is deactivated in multiple BWP.In this way, the network equipment can be supported through DL assignment or UL The activation of grant signaling deactivates downlink BWP or uplink BWP, so that the scheduling of the network equipment is more flexible.

In embodiments of the present invention, the index of the existing first field instruction BWP of instruction information can be used.Work as instruction The data in the currently active BWP are dispatched, that is, when not needing to activate other BWP, need not actually be indicated to terminal device The index of the currently active BWP.At this point, the first field indicates the information oneself characterized originally；When instruction is dispatched in other BWP Data, that is, when needing to activate other BWP, the first field can be used to refer to the index for the BWP being activated.

In detailed below using the index of which field instruction BWP, and how to use these fields instruction BWP's index.Specifically:

The first, the index of BWP is indicated using the part of resource allocation (resource allocation, RA) field. That is indicate that the index of BWP, these bits in RA field no longer indicate its script by the partial bit of RA field The information of characterization, such as: resource allocation conditions.

It is exemplary, by taking RA field is used to indicate frequency domain resource as an example, use frequency resource allocation Type0 indicates that frequency domain resource, frequency domain resource for unit, are passed through with Physical Resource Block group (resource block group, RBG) Bitmap indicates the resource allocation conditions of some UE.Such as: as soon as current frequency domain resource shares 20 RBG, then with 20 bit To indicate frequency domain resource distribution condition, the corresponding RBG of each bit.The state value of the corresponding bit of one RBG is " 1 " generation The distribution condition of the table RBG are as follows: be allocated to UE (i.e. terminal device described in the embodiment of the present invention), state value is " 0 " generation The distribution condition of the table RBG are as follows: be not allocated to the UE.

Assuming that be configured with 4 BWP, including 2 uplink BWP and 2 downlink BWP, and the mutual not phase of the index of 4 BWP Together, then 2bits can be used to indicate the index of BWP.Further, it is possible to indicate BWP using preceding 2 bit of RA field Index.

At this point, the distribution condition of corresponding two RGB of preceding 2 bit of RA field is defaulted not to be assigned to UE, alternatively, The distribution condition for defaulting corresponding two RGB of preceding 2 bit of RA field is to be assigned to the UE.Or according to RA field 3rd bit determines the distribution condition of corresponding two RGB of preceding 3 bit, if the 3rd bit is 0, then it represents that preceding 3 bit The distribution condition of corresponding 3 RBG is to be not allocated to the UE；If the 3rd bit is 1, then it represents that preceding 3 bit are corresponding The distribution condition of 3 RBG is to be allocated to the UE.

Above be only used to indicate for frequency domain resource to RA field is illustrated, and RA field may be used to indicate that time domain Resource or running time-frequency resource, at this point, similar using the implementation of the index of RA field instruction BWP, details are not described herein again.

It should be noted that described above only using the possible realization side of one kind of the index of RA field instruction BWP Formula can also have other implementations using the index of RA field instruction BWP, and comparison of the embodiment of the present invention is not construed as limiting.

The second, using the index of resource group instruction (resource set (s) indication) field instruction BWP.

As shown in figure 4, introducing the concept of resource set in 5G NR (New Radio), i.e., in transmission PDCCH Symbol on, having some resources is not occupied by PDCCH, these not by PDCCH occupy resource, that is, resource Set, resource set can also be configured to PDSCH use, and the network equipment (such as: base station) can use resource set Down user data is sent to terminal device (such as: UE).Further, base station can be that UE configuration is one or more by RRC signaling Resource set, then indicate which set is UE available by the use resource group indication field in DCI, which be UE not It is available.

Current BWP (BWP1) is deactivated, activates new BWP (BWP2) when there is across BWP scheduling UE with reference to Fig. 5 When, carried out data transmission by new BWP and UE.UE decoding PDCCH needs the regular hour, jumps to BWP2 from BWP1 and is also required to Regular hour will lead to have certain time interval between PDCCH and PDSCH.At this point, UE is waited to be switched to BWP2 progress When data receiver, the time-domain symbol where resource set on BWP2 is sent already, and UE can not receive base station The data sent on these resource set.Meanwhile UE can't be cached on BWP2 when on BWP1 with base station communication Data, therefore, the resource set when BWP switching occurs on BWP2 obviously cannot be used to the UE again.

To sum up, there is across BWP scheduling, that is, when activating new BWP, using resource group indication field virtually free from work ?.The field can be used at this time to indicate the index of BWP.

Third, the index that BWP is indicated using redundancy versions (redundant version, RV) field.

For initial data after being encoded, the different sets of coded bits (coded bit) are referred to as different RV. When being retransmitted after transmission failure, transmitting different RV (i.e. different coded bit set) can have than transmitting identical RV It is higher to be decoded into power.

There is across BWP scheduling, that is, when activating new BWP, is defaulting scheduled data and use RV=0.At this point, RV field It may be used for the index of instruction BWP.

4th, indicate BWP's using transmission power control (transmission power control, TPC) field index。

In general, the transmission power of UE is controlled by base station, in DCI, (i.e. instruction described in the embodiment of the present invention is believed for base station Breath) in can indicate the transmission power of UE.Transmission power control is divided into two kinds: accumulation TPC (cumulative formula power control) With absolute TPC (absolute value formula power control).When UE uses accumulation TPC, changed power is indicated in DCI Value, the changing value add up to the final power control value of UE with accumulated value before；It is straight in DCI when using absolute TPC It connects and indicates final power control value.

When UE uses accumulation TPC, defaults and indicate that power change values are 0 in the secondary DCI, then UE can Using the power control value that accumulated value before is final as UE, DCI is not necessarily to indicated horsepower changing value at this time, and base station can use The index of TPC command field instruction BWP.

Alternatively, defaulting the closed-loop power control value indicated in the secondary DCI when UE uses absolute TPC and nearest one same It is identical in type TPC command.DCI is without indicating final power control value at this time, then base station can use TPC The index of command field instruction BWP.

5th, using modulating-coding strategy, ((mymova checkin system, MCS) field indicates BWP's index。

Usual MCS field is used to indicate the modulation system of current transmission, it is assumed that the length of MCS field is 5 bit, configuration 4 BWP, including 2 uplink BWP and 2 downlink BWP, and the index of 4 BWP is different, then can be used 2bits indicates the index of BWP.Preceding 2 bit of MCS field can be used to indicate the index of BWP.

Further, remaining 3 bits of MCS field still can be with the available MCS of indicating section.Alternatively, MCS field is remaining 3 bits as reserved (reservation does not have to), use the MCS of a default.Or remaining 3 bits of MCS field As reserved (reservation does not have to), identical MCS is once transmitted using with preceding.

It is introduced in bandwidth indicating means provided in an embodiment of the present invention for indicating that information is DCI and specifically how to be referred to below Show the index of BWP.

For the downlink DCI signal of dispatching downlink data, there are following 3 kinds of situations:

Situation 1: downlink DCI indicates that uplink a BWP, UE activate the uplink BWP, UE to send uplink on uplink BWP Data, such as: the ACK or NACK of feeding back downlink data (i.e. according to the received downlink data of instruction of downlink DCI) reception condition, Or transmission SRS, PUSCH, SR, CSI/CQI feedback etc..

Situation 2: downlink DCI indicates a downlink BWP, at this point, UE has following two reception possible:

The first, as shown in fig. 6, UE is received on the currently active downlink BWP (BWP1) (i.e. base station sends the downlink DCI) The downlink data of downlink DCI scheduling, but the downlink BWP of downlink DCI instruction is switched in next slot (time slot) (BWP2) on, the subsequent downlink data for receiving base station on downlink BWP and sending

The second, as shown in fig. 7, UE receives downlink DCI, the downlink of downlink DCI instruction is switched in current slot On BWP (BWP2), the downlink data of downlink DCI scheduling is received on the downlink BWP (BWP2) of downlink DCI instruction.

Compared to second implementation, the first implementation can reduce the scheduler latency of PDSCH, and can dispatch Unused resource in PDCCH is that UE transmits data.

Situation 3: downlink DCI indicates the currently active uplink BWP or the currently active downlink BWP, that is to say, that without swashing New BWP living.Then UE receives the downlink data of DCI scheduling on the currently active downlink BWP, and in the currently active uplink ACK/NACK of the downlink data, or transmission SRS, PUSCH, SR, CSI/CQI feedback etc. are fed back on BWP.

For the uplink DCI signal of dispatching uplink data, there are following 3 kinds of situations:

Situation 1: uplink DCI indicate downlink a BWP, UE received on the downlink BWP that uplink DCI is indicated it is subsequent under Row data, such as: for carrying out the DCI of uplink scheduling, the DCI for being used to indicate downlink transfer, down user data.

Situation 2: uplink DCI indicates uplink a BWP, UE, and there is also following two transmission is possible:

The first, it after UE receives uplink DCI, switches on the uplink BWP of uplink DCI instruction, is sent out on uplink BWP The upstream data and subsequent upstream data for giving uplink DCI to dispatch.

The second, UE sends the upstream data of uplink DCI scheduling on the currently active uplink BWP, but next Slot is switched on the uplink BWP of uplink DCI instruction, subsequent that upstream data or upload control letter are sent on uplink BWP Number.
