Referring to Fig. 2, portions of bandwidth transform method of the invention the following steps are included:

Step 201, DCI is received on time quantum n, the band of the activation portions of bandwidth instruction information instruction activation in DCI Wide portion transformation.

Activation portions of bandwidth instruction information can indicate that activation portions of bandwidth is current activation portions of bandwidth (i.e. activating belt Wide portion does not convert), it can also indicate that activation portions of bandwidth is that (i.e. activation portions of bandwidth is become new portions of bandwidth It changes).

Step 202, according to the activation portions of bandwidth instruction information (if activation portions of bandwidth is converted) received Determine the time quantum n+k of the portions of bandwidth of transformation activation.

Here k value is a nonnegative integer, is the parameter of the invention to be determined, the value of parameter k swashs according to instruction The type of DCI and the type of frequency spectrum of portions of bandwidth transformation living determine.For example, passing through the portions of bandwidth of DL DCI instruction activation The possible difference of k value of the k value of transformation and the portions of bandwidth transformation by UL DCI instruction activation, needs to be independently determined, in addition, at The k value of the portions of bandwidth transformation activated in k value and non-paired frequency spectrum to the portions of bandwidth transformation activated on frequency spectrum may be different, It needs to be independently determined, the method that will be described in determining k value in embodiments of the present invention.Alternatively, whether DL DCI instruction swashs The k value of the k value of portions of bandwidth transformation living and the portions of bandwidth transformation by UL DCI instruction activation, and it is directed to paired spectrum The k value of the portions of bandwidth transformation activated in the k value of the portions of bandwidth transformation of upper activation and non-paired frequency spectrum is all the same, for example, k etc. In 1.

The value of k can (such as k value is equal to 1) default by agreement, or it is (such as distinctive by UE by high-level signaling configuration High-level signaling configuration), or by physical layer signaling instruction (for example, using the bit indication in DCI, can be with the PDSCH of scheduling Or PUSCH uses identical k value).

Lower line activating BWP, the activation BWP for receiving PDCCH and PDSCH can be started to convert in same time slot, it can also To start to convert in different time-gap, for uplink activation BWP, the activation BWP for sending PUCCH and PUSCH can be in same time slot Start to convert, can also start to convert in different time-gap.

When for one DCI instruction transformation of pairs of uplink activation BWP and lower line activating BWP, uplink activation BWP is under Line activating BWP can start to convert in same time slot, can also start to convert in different time-gap.

Step 203, it is activated since time quantum n+k in downlink and receives PDCCH and/or PDSCH in portions of bandwidth, and/ Or PUCCH and/or PUSCH is sent in uplink activation portions of bandwidth.

The method of portions of bandwidth transformation of the invention can be applied to the channel radio that UE is configured at least two portions of bandwidth Letter system, and an at most uplink activation BWP and at most a lower line activating BWP simultaneously.Time quantum of the present invention can To be the chronomere as unit of time slot, OFDM symbol or OFDM symbol group etc..It is main to use in the specific embodiment of the invention Be to be illustrated in case where unit is scheduled by time slot (slot), the method for the present invention can simply expand to not with The case where time slot is scheduled for unit (for example, thread is as unit of OFDM symbol or OFDM symbol group).Lead to below The method for crossing several embodiments to illustrate activation portions of bandwidth transformation of the invention.

Embodiment one

In paired spectrum, (i.e. uplink and downlink transfer use different frequency ranges, such as frequency division pair for the present embodiment description Work (FDD, Frequency Division Multiplexing)) in the case of, UE is by receiving the activation of DL DCI indicating downlink The method of BWP transformation, that is, the DCI that UE receives indicating downlink activation BWP transformation in time slot n, are becoming since time slot n+k PDCCH or PDSCH is received in lower line activating BWP after changing.Under thering is following several method to determine that UE starts after the conversion below The time quantum of PDCCH or PDSCH is received in line activating BWP.

Method one:

If the DL DCI of indicating downlink activation BWP transformation scheduled the PDSCH of a time slot, and indicating downlink activates Instruction information indicating downlink activation BWP in the DCI of BWP transformation has occurred transformation and (namely descends line activating BWP from current transmission BWP where DCI has been transformed into an other downlink BWP), and PDSCH and dispatch its DCI in same time slot, then UE from The time slot starts to receive PDSCH on lower line activating BWP after the conversion, first after the time slot for receiving PDSCH Descending time slot starts to receive PDCCH on lower line activating BWP after the conversion.

As shown in Figure 3, it is assumed that UE is configured with two downlink BWP, respectively BWP-1 and BWP-2, and in time slot n, UE is in BWP- The DCI (DCI is transmitted by PDCCH) of indicating downlink activation BWP transformation is detected on 1, which scheduled on BWP-2 The PDSCH (indicate activation BWP from BWP-1 be transformed to BWP-2) of transmission, and PDSCH is also transmitted in time slot n, then UE is from time slot n Start to receive PDSCH on BWP-2, receives PDCCH on BWP-2 since time slot n+1.It can make to activate using this method The instruction of BWP transformation comes into force as early as possible.

Method two:

If the DL DCI of indicating downlink activation BWP transformation scheduled the PDSCH of a time slot, and indicating downlink activates Instruction information indicating downlink activation BWP in the DCI of BWP transformation has occurred transformation and (namely descends line activating BWP from current transmission BWP where DCI has been transformed into an other downlink BWP), and PDSCH and dispatch its DCI in different time-gap, then UE from Time slot where PDSCH starts to receive PDSCH on lower line activating BWP after the conversion, first after time slot where from PDSCH Descending time slot starts to receive PDCCH on lower line activating BWP after the conversion.

It is assumed that UE is configured with two downlink BWP, respectively BWP-1 and BWP-2, in time slot n, UE is in BWP- The DCI (DCI is transmitted by PDCCH) of indicating downlink activation BWP transformation is detected on 1, which scheduled in time slot n+L (L is a positive integer, for example, being configured by high-level signaling by the physical layer signaling instruction in DCI or being preset by agreement) The PDSCH transmitted on BWP-2, then UE receives PDSCH since time slot n+L on BWP-2, since time slot n+L+1 PDCCH is received on BWP-2, and PDCCH is received on BWP-1 in time slot n+1 to time slot n+L, UE.It can be avoided using this method more Secondary BWP converts bring resource consumption.

Method three:

If the DL DCI of indicating downlink activation BWP transformation scheduled the PDSCH of a time slot, and indicating downlink activates Instruction information indicating downlink activation BWP in the DCI of BWP transformation has occurred transformation and (namely descends line activating BWP from current transmission BWP where DCI has been transformed into an other downlink BWP), and PDSCH and dispatch its DCI in different time-gap, then UE from Time slot where PDSCH starts to receive PDSCH on lower line activating BWP after the conversion, and is converting the time slot where PDSCH PDCCH is received on lower line activating BWP afterwards.

As shown in fig. 5, it is assumed that UE is configured with two downlink BWP, respectively BWP-1 and BWP-2, in time slot n, UE is in BWP- The DCI (DCI is transmitted by PDCCH) of indicating downlink activation BWP transformation is detected on 1, which scheduled in time slot n+L (L is a positive integer, for example, being configured by high-level signaling by the physical layer signaling instruction in DCI or being preset by agreement) The PDSCH transmitted on BWP-2, then UE receives PDSCH since time slot n+L on BWP-2, and since time slot n+L PDCCH is received on BWP-2, and PDCCH is received on BWP-1 in time slot n+1 to time slot n+L-1, UE.

Method four:

If the DL DCI of indicating downlink activation BWP transformation scheduled the PDSCH of a time slot, and indicating downlink activates Instruction information indicating downlink activation BWP in the DCI of BWP transformation has occurred transformation and (namely descends line activating BWP from current transmission BWP where DCI has been transformed into an other downlink BWP), and PDSCH with dispatch its DCI in different time-gap or identical Time slot, UE from indicating downlink activation BWP convert DCI after m (m is a nonnegative integer, can be preset by agreement, or Person is configured by high-level signaling, starts to receive PDCCH on lower line activating BWP after the conversion for example, m is equal to 1) a descending time slot, PDSCH is received on lower line activating BWP the time slot where PDSCH after the conversion.

As shown in Figure 6, it is assumed that UE is configured with two downlink BWP, respectively BWP-1 and BWP-2, and in time slot n, UE is in BWP- The DCI (DCI is transmitted by PDCCH) of indicating downlink activation BWP transformation is detected on 1, which scheduled in time slot n+L (L is a positive integer, for example, being configured by high-level signaling by the physical layer signaling instruction in DCI or being preset by agreement) The PDSCH transmitted on BWP-2, then UE receives PDSCH since time slot n+L on BWP-2, from time slot n+1 (assuming that such as preceding institute 1) m stated, which is equal to, to be started to receive PDCCH on BWP-2.It can be connect on lower line activating BWP as early as possible after the conversion using this method PDCCH and PDSCH is received, it is likely that bringing resource consumption because of multiple BWP transformation.For example, it is assumed that UE is configured under two Row BWP, respectively BWP-1 and BWP-2, in time slot n, UE detects the DCI of indicating downlink activation BWP transformation on BWP-1 (DCI is transmitted by PDCCH), which scheduled the PDSCH transmitted on BWP-2 in time slot n+3, then UE exists in time slot n+3 PDSCH is received on BWP-2, UE detects PDCCH in time slot n+1 and time slot n+2 on BWP-2, it is assumed that UE is detected in time slot n-2 The PDSCH of DCI scheduling is transmitted on BWP-1 in time slot n+1, and UE detects the PDSCH of DCI scheduling in time slot n+2 in time slot n-1 It is transmitted on BWP-1, such UE receives PDCCH in time slot n on BWP-1, first transforms to BWP-2 in time slot n+1 and receives Then PDCCH transforms to BWP-1 in time slot n+1 again and receives PDSCH, first transform to BWP-2 in time slot n+2 and receive PDCCH, so BWP-1 is transformed to again in time slot n+2 afterwards and receives PDSCH, is transformed to BWP-2 in time slot n+3 and is received PDCCH, then in time slot n+3 PDSCH is received in BWP-2, as shown in Figure 7.The transformation occurred between multiple BWP-1 and BWP-2 is done so, using this method PDCCH and PDSCH can be received on lower line activating BWP as early as possible after the conversion, it is likely that multiple BWP is brought to convert, from And lead to additional resource consumption.

Method five

If the DL DCI of indicating downlink activation BWP transformation scheduled the PDSCH of a time slot, and indicating downlink activates Instruction information indicating downlink activation BWP in the DCI of BWP transformation has occurred transformation and (namely descends line activating BWP from current transmission BWP where DCI has been transformed into an other downlink BWP), then UE receives PDSCH on the activation BWP not converted, and (m is a nonnegative integer to m after the DCI that indicating downlink activates BWP to convert, can be default by agreement, or passes through high level Signal deployment, such as m are equal to 1) a descending time slot and start to receive PDCCH on lower line activating BWP after the conversion.

As shown in Figure 8, it is assumed that UE is configured with two downlink BWP, respectively BWP-1 and BWP-2, and in time slot n, UE is in BWP- The DCI (DCI is transmitted by PDCCH) of indicating downlink activation BWP transformation is detected on 1, which scheduled on time slot n The PDSCH of transmission, then UE receives PDSCH in time slot n on BWP-1, and from time slot n+p, (p is determined by agreement, or believed by high level Configuration is enabled, 1) starts to receive PDCCH on BWP-2 for example, p is equal to.The unit that this method is also applied for scheduling is not with time slot The case where for unit, if the unit of scheduling be not as unit of time slot, such as with 2 OFDM symbols for a unit, PDCCH With the PDCCH scheduling PDSCH same 2 OFDM symbols unit transmit, then without grace time as BWP convert when Between be spaced, therefore transmit PDSCH BWP with dispatch the BWP of PDCCH of the PDSCH it is identical, in another time quantum later PDCCH lower line activating BWP after the conversion on receive.

The case where dispatching the transmission of the PDSCH of at least two time slots for a PDCCH, five kinds of methods above still may be used To be applicable in, only the PDSCH of the scheduling becomes first in the PDSCH of at least two time slots of PDCCH scheduling A PDSCH.For example, corresponding to above method one, the feelings of the transmission of the PDSCH of at least two time slots are dispatched in a PDCCH It can become under condition as follows: if the DCI of indicating downlink activation BWP transformation scheduled the PDSCH of at least two time slots, and indicate Instruction information indicating downlink activation BWP in the DCI of lower line activating BWP transformation have occurred transformation (namely descend line activating BWP from BWP where current transmission DCI has been transformed into an other downlink BWP), and first time slot in described two time slots PDSCH and the DCI for dispatching it are then received on lower line activating BWP of the UE since the time slot after the conversion in same time slot PDSCH is connect on lower line activating BWP after the conversion first descending time slot after the time slot for receiving PDSCH Receive PDCCH.As shown in Figure 9, it is assumed that UE is configured with two downlink BWP, respectively BWP-1 and BWP-2, and in time slot n, UE is in BWP- The DCI (DCI is transmitted by PDCCH) of indicating downlink activation BWP transformation is detected on 1, which scheduled on BWP-2 The PDSCH of transmission, and PDSCH is transmitted in time slot n and time slot n+1, then UE is received on BWP-2 since time slot n and time slot n+1 PDSCH, UE receive PDCCH since time slot n+1 on BWP-2.This replacement is equally applicable to method two to method five.

Embodiment two

The present embodiment is described in paired spectrum, and UE indicates the side of uplink activation BWP transformation by receiving UL DCI Method, that is, UE receive the DCI of instruction uplink activation BWP transformation, the uplink since time slot n+k after the conversion in time slot n It activates and sends PUSCH or PUCCH in BWP.

If indicating that the UL DCI of uplink activation BWP transformation scheduled the PUSCH of a time slot, and the ULDCI refers to simultaneously Show that uplink activation BWP is converted, is then sent out on uplink activation BWP of the UE since scheduled PUSCH time slot after the conversion Send PUSCH and PUCCH.As shown in Figure 10, it is assumed that UE is configured with two uplink BWP, respectively BWP-1 and BWP-2, and UE is in time slot N has received the UL DCI (DCI is transmitted by PDCCH) of instruction uplink activation BWP transformation, the uplink activation before time slot n BWP is BWP-1, which scheduled the PUSCH sent on BWP-2, while indicating that uplink activation BWP becomes BWP- from BWP-1 2, and PUSCH time slot n+k send, then UE sends PUSCH since time slot n+k on BWP-2, since time slot n+k PUCCH is sent on BWP-2.Uplink activation BWP becomes BWP-2 in time slot n+k, the uplink of UE after the conversion since time slot n+k It activates and sends PUSCH and PUCCH on BWP-2.

Embodiment three

The present embodiment description non-paired frequency spectrum (i.e. identical frequency band not only carries out uplink, but also carries out downlink transfer, such as Time division duplex (TDD, Time Division Multiplexing)) in the case of, UE is by receiving the activation of DL DCI indicating downlink Method of the BWP and uplink activation BWP to transformation.Namely UE receives indicating downlink activation BWP and uplink activation in time slot n BWP receives PDCCH or PDSCH, from time slot n+ to the DCI of transformation since the lower line activating BWP time slot n+k1 after the conversion K2 starts to send PUCCH or PUSCH in uplink activation BWP after the conversion.The k1 and k2 can be identical, that is, from same Time quantum starts the transformation of lower the line activating BWP and uplink activation BWP of lower line activating BWP and uplink activation BWP centering；It is described K1 and k2 can be independently determined, and k1 and k2 can be identical at this time, can not also be identical, that is, since different time unit under The transformation of line activating BWP and lower the line activating BWP and uplink activation BWP of uplink activation BWP centering.The present embodiment provides following several Kind of method determines that UE starts to receive the time quantum of PDCCH or PDSCH in lower line activating BWP after the conversion and UE starts becoming The time quantum of PUCCH or PUSCH is sent in uplink activation BWP after changing.

Method one

UE activates BWP and uplink activation BWP to the method for transformation by receiving DL DCI indicating downlink, that is, UE when Gap n receives downlink of the indicating downlink activation BWP and uplink activation BWP to the DCI of transformation, since time slot n+k1 after the conversion Activate BWP in receive PDCCH or PDSCH, since the uplink activation BWP time slot n+k2 after the conversion send PUCCH or PUSCH.In this method, the k1 and k2 is identical, that is, lower line activating BWP and uplink activation since same time quantum The transformation of lower the line activating BWP and uplink activation BWP of BWP centering.Namely UE receives indicating downlink activation BWP in time slot n With uplink activation BWP to the DCI of transformation, received since the lower line activating BWP time slot n+k after the conversion PDCCH or PDSCH sends PUCCH or PUSCH since the uplink activation BWP time slot n+k after the conversion.

Wherein, the time quantum that UE starts to receive PDCCH or PDSCH in lower line activating BWP after the conversion can use Method one in embodiment one is to this five kinds of methods of method five.

And the time quantum that UE starts to send PUCCH or PUSCH in the uplink activation BWP to after uplink conversion is above-mentioned reality After applying the time quantum that UE in each method of example one starts to receive PDCCH or PDSCH in lower line activating BWP after the conversion The time quantum that first time uplink is sent, the first time uplink transmission can be PUCCH transmission, be also possible to PUSCH transmission.

For example, UE receives indicating downlink activation BWP and uplink activation BWP to the DCI of transformation in time slot n, the DCI is under Row BWP-1 is transmitted, and the indicating downlink activation BWP and uplink activation BWP in the DCI activates the instruction information indicating downlink of transformation BWP and uplink activation BWP scheduled the PDSCH, the PDSCH of time slot n transmission to converting, while in time slot n, the DCI Lower line activating BWP-2 transmission after the conversion, does not have uplink part in time slot n, and time slot n+1 is ascending time slot, then UE from Time slot n+1 starts to send PUCCH and/or PUSCH on uplink activation BWP-2 after the conversion (if the time slot needs to transmit PUCCH and/or PUSCH), as shown in figure 11.

Method two

UE activates BWP and uplink activation BWP to the method for transformation by receiving DL DCI indicating downlink, that is, UE when Gap n receives downlink of the indicating downlink activation BWP and uplink activation BWP to the DCI of transformation, since time slot n+k1 after the conversion Activate BWP in receive PDCCH or PDSCH, since the uplink activation BWP time slot n+k2 after the conversion send PUCCH or PUSCH.In this method, the k1 and k2 are independently determined, can be identical or not identical, for example, k1 is less than or equal to k2, also It is lower line activating BWP and the uplink activation BWP started in lower line activating BWP and BWP couples of uplink activation in different time unit Transformation.Namely UE receives indicating downlink activation BWP and uplink activation BWP to the DCI of transformation, from time slot n+k1 in time slot n Start to receive PDCCH or PDSCH, the uplink activation since time slot n+k2 after the conversion in lower line activating BWP after the conversion PUCCH or PUSCH is sent in BWP.The collision of uplink PUCCH and PUSCH resource can be reduced using this method.

Wherein, UE starts to receive in lower line activating BWP after the conversion in the time quantum n+k1 of PDCCH or PDSCH K1 can to method five, this five kinds of methods be obtained using the method one in embodiment one.

And UE starts to send in the uplink activation BWP to after uplink conversion in the time quantum n+k2 of PUCCH or PUSCH K2 can activate BWP and uplink activation BWP to dispatch the HARQ-ACK transmission of the DCI of transformation or the DCI according to indicating downlink PDSCH HARQ-ACK transmission time quantum (for example, indicating downlink activates BWP and uplink activation BWP to the DCI of transformation Transmitted in time slot n, the HARQ-ACK that the PDSCH of DCI scheduling is generated in n+m slot transmission, then the uplink activation BWP of UE when Gap n+m is converted, i.e. k2, which is equal to, m) to be determined, transformation takes place from the time quantum in the uplink activation BWP of UE, and UE is being converted Uplink activation BWP afterwards sends PUCCH and/or sends PUSCH.Alternatively, k2 can be default by agreement, matched by high-level signaling It sets, or is individually indicated by physical layer signaling, for example, k2 is equal to 4.Or it is true according to the scheduling timing relationship of uplink PUSCH It is fixed, for example, indicating downlink activates BWP and uplink activation BWP to transmit the DL DCI of transformation in time slot n, the scheduling timing of PUSCH Relationship is: whether, if the DCI of scheduling PUSCH is transmitted in time slot n, UE transmits PUSCH in time slot n+p, then no matter have in time slot n PUSCH scheduling, as long as UE receives indicating downlink activation BWP and uplink activation BWP to the DL DCI of transformation in time slot in time slot n N transmission, then uplink activation BWP is converted in time slot n+p, i.e. k2 is equal to p, since time slot n+p, the uplink of UE after the conversion It activates BWP to send PUCCH and/or sends PUSCH.

For example, UE receives indicating downlink activation BWP and uplink activation BWP to the DCI of transformation in time slot n, the DCI is under Row BWP-1 is transmitted, and the indicating downlink activation BWP and uplink activation BWP in the DCI activates the instruction information indicating downlink of transformation BWP and uplink activation BWP scheduled the PDSCH, the PDSCH of time slot n transmission to converting, while in time slot n, the DCI Lower line activating BWP-2 transmission after the conversion, according to HARQ timing relationship, the HARQ-ACK of the PDSCH is transmitted in time slot n+2, Time slot n+1 and time slot n+2 is ascending time slot, then UE time slot n+1 sent on the uplink activation BWP-1 not converted PUCCH and/ Or PUSCH (if the time slot needs to transmit PUCCH and/or PUSCH), uplink of the UE since time slot n+2 after the conversion It activates and sends PUCCH and/or PUSCH (if the time slot needs to transmit PUCCH and/or PUSCH) on BWP-2, such as Figure 12 It is shown.

It can avoid the collision of PUCCH and PUSCH resource as far as possible using the method.For example, UE is in lower line activating BWP-1, DCI is received in time slot n-1, which scheduled PDSCH, and PDSCH is transmitted in time slot n-1, and PDSCH is in lower line activating BWP-1 Transmission, the HARQ-ACK of the PDSCH of time slot n-1 time slot n+1 uplink activation BWP-1 transmission (because in time slot n-1, base It stands and does not know that uplink activation BWP will change, base station is provided according to the PUCCH that HARQ-ACK is distributed is transmitted on uplink activation BWP-1 Source, if according to the uplink activation BWP-2 of the variation for the DCI instruction transmitted in time slot n, time slot n+1 transmission time slot n-1's The HARQ-ACK that PDSCH is generated, then may (PUSCH passes through the uplink DCI of n-1 time slot with the PUSCH that dispatch in time slot n+1 Scheduling) generate collision), UE receives indicating downlink activation BWP and uplink activation BWP in time slot n and exists to the DCI of transformation, the DCI Downlink BWP-1 is transmitted, and the indicating downlink activation BWP and uplink activation BWP in the DCI swashs the instruction information indicating downlink of transformation BWP and uplink activation BWP living scheduled the PDSCH of time slot n transmission in time slot n, the DCI to converting, should The lower line activating BWP-2 transmission of PDSCH after the conversion, according to HARQ timing relationship, the HARQ-ACK of the PDSCH is in time slot n+2 Transmission, n+2 are ascending time slots, and UE sends PUCCH transmission time slot n's on time slot n+2 uplink activation BWP-2 after the conversion The HARQ-ACK that PDSCH is generated, as shown in figure 13.If not using this method, PUCCH and PUSCH will be as shown in figure 13 upper Row time slot n+1 collides in BWP-2.

Example IV

The present embodiment describes under non-paired spread spectrum scenarios, and UE activates BWP and uplink by receiving UL DCI indicating downlink Activate BWP to the method for transformation.Namely UE receives indicating downlink activation BWP and uplink activation BWP to transformation in time slot n DCI receives PDCCH or PDSCH since the lower line activating BWP time slot n+k1 after the conversion, is becoming since time slot n+k2 PUCCH or PUSCH is sent in uplink activation BWP after changing.The k1 and k2 can be identical, that is, opens from same time quantum The transformation of line activating BWP and lower the line activating BWP and uplink activation BWP of uplink activation BWP centering under beginning；The k1 and k2 is independent It determines, at this point, k1 and k2 can be identical or not identical, that is, the lower line activating BWP and upper since different time unit The transformation of lower the line activating BWP and uplink activation BWP of line activating BWP centering.The present embodiment provides several methods to determine that UE starts The time quantum of PDCCH or PDSCH is received in lower line activating BWP after the conversion and UE starts uplink activation after the conversion The time quantum of PUCCH or PUSCH is sent in BWP.

Method one

UE activates BWP and uplink activation BWP to the method for transformation by receiving UL DCI indicating downlink, that is, UE when Gap n receives downlink of the indicating downlink activation BWP and uplink activation BWP to the DCI of transformation, since time slot n+k1 after the conversion Activate BWP in receive PDCCH or PDSCH, since the uplink activation BWP time slot n+k2 after the conversion send PUCCH or PUSCH.In this method, the k1 and k2 is identical, that is, lower line activating BWP and uplink activation since same time quantum The transformation of lower the line activating BWP and uplink activation BWP of BWP centering.Namely UE receives indicating downlink activation BWP in time slot n With uplink activation BWP to the UL DCI of transformation, received since the lower line activating BWP time slot n+k after the conversion PDCCH or PDSCH sends PUCCH or PUSCH since the uplink activation BWP time slot n+k after the conversion.If indicating downlink activates BWP and uplink activation BWP scheduled PUSCH to the UL DCI of transformation, and PUSCH is transmitted in time slot m, and k value can be obtained according to m Out, such as k is equal to m.Alternatively, k value can be default by agreement, high-level signaling configuration or physical layer signaling instruction.

For example, UE activates BWP and uplink activation BWP to the method for transformation by receiving UL DCI indicating downlink, that is, UE receives indicating downlink activation BWP and uplink activation BWP to the UL DCI of transformation in time slot n-1, indicating downlink activate BWP and Uplink activation BWP from BWP-1 is transformed to BWP-2 to transformation, which scheduled the PUSCH sent in time slot n+1, UE from when Gap n+1 starts to receive PDCCH or PDSCH in lower line activating BWP after the conversion, UE after the conversion upper since time slot n+1 PUCCH or PUSCH is sent in line activating BWP, as shown in figure 14.

Method two

UE activates BWP and uplink activation BWP to the method for transformation by receiving UL DCI indicating downlink, that is, UE when Gap n receives downlink of the indicating downlink activation BWP and uplink activation BWP to the DCI of transformation, since time slot n+k1 after the conversion Activate BWP in receive PDCCH or PDSCH, since the uplink activation BWP time slot n+k2 after the conversion send PUCCH or PUSCH.In this method, the k1 and k2 are independently determined, can be identical or not identical, for example, k1 is less than or equal to k2.

K1 therein can determine that (for example, k1 is equal to 1, that is, UE is received under instruction in time slot n by the way that agreement is default Line activating BWP and uplink activation BWP is to the instruction information indicating downlink activation BWP and uplink activation BWP in the DCI of transformation to hair Transformation is given birth to, then UE receives PDCCH or PDSCH since the lower line activating BWP time slot n+1 after the conversion), or pass through height Layer signal deployment, and k2 therein can be determined using the method one in the present embodiment.
