In a New wireless (NR) system of 5G, a concept of BandWidth Part (BWP) is introduced, and a terminal device may configure multiple BWPs, and activate only one BWP at a time, and the BWP may correspond to one BWP deactivation timer (inactivity timer), and when the BWP deactivation timer expires (or is disabled), the terminal device may switch the currently activated BWP to a default BWP or an initial BWP.

However, if the BWP deactivation timer times out when data transmission is not completed, the BWP switch will interrupt data transmission, and thus a solution to the above problem is needed.

Therefore, according to the method for transmitting data of the embodiment of the present application, if the BWP deactivation timer expires when the data channel does not start transmission or does not finish transmission, the terminal device starts or restarts the BWP deactivation timer, so that the terminal device can remain on the currently activated BWP to continue data transmission, and data transmission interruption due to BWP switching can be avoided.

In one possible implementation, before the end device restarts the first BWP deactivation timer, the method further includes: the terminal device suspends BWP handover.

and the terminal equipment performs BWP switching under the condition that the data channel transmission is finished.

Therefore, according to the method for transmitting data of the embodiment of the present application, if the BWP deactivation timer expires when the data channel does not start transmission or finish transmission, the terminal device may suspend BWP switching without processing the first BWP deactivation timer, and then continue to transmit the data channel on the first BWP, and perform BWP switching when the data channel finishes transmission, thereby avoiding interruption of data transmission due to BWP switching.

Detailed Description

The technical solution of the embodiment of the present application can be applied to various communication systems, such as a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a long Term Evolution (L on Term Evolution (L TE) System, a L TE Frequency Division Duplex (FDD) System, a L TE Time Division Duplex (WiMAX), a Universal Mobile Telecommunications System (UMTS) System, a Worldwide Interoperability for Microwave Access (WiMAX) System, or a future communication System, such as a UMTS System.

Fig. 1 illustrates a wireless communication system 100 to which an embodiment of the present invention is applied, the wireless communication system 100 may include a Network device 110, the Network device 100 may be a device that communicates with a terminal device, the Network device 100 may provide communication coverage for a specific geographic area, and may communicate with a terminal device (e.g., UE) located within the coverage area, alternatively, the Network device 100 may be a Base Transceiver Station (BTS) in a GSM system or a CDMA system, a Base Station (NodeB, NB) in a WCDMA system, an evolved Node B (eNB, or eNodeB) in a L TE system, or a wireless controller in a Cloud Radio Access Network (CRAN), or the Network device may be a relay Station, an Access point, a vehicle-mounted device, a wearable device, a Network-side device in a future 5G Network, or a Network device in a future evolved Public land Mobile Network (MN L, L, etc.).

The Wireless communication system 100 also includes at least one terminal device 120 located within the coverage of the network device 110. the terminal device 120 may be mobile or fixed. alternatively, the terminal device 120 may refer to an access terminal, a User Equipment (UE), a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a User terminal, a Wireless communication device, a User agent, or a User Equipment.

In the communication system, a Physical Downlink Control CHannel (Physical Downlink Control CHannel PDCCH) may schedule a Physical Downlink Shared CHannel (PDSCH) for Downlink data transmission, or may schedule a Physical Uplink Shared CHannel (PUSCH) for Uplink data transmission, where a time interval between the PDCCH and the PDSCH is K0, a time interval between the PDCCH and the PUSCH is K2, that is, an interval from the end of PDCCH to the end of PDSCH transmission is K0, and an interval from the end of PDCCH to the end of PUSCH transmission is K2, where a value of K0/K2 may be 32ms at the maximum.

However, the duration of the BWP deactivation timer is usually short, for example, 1ms, 2ms, etc., and if the BWP deactivation timer expires during the transmission of the PDSCH or PUSCH or if the BWP deactivation timer expires when the transmission of the PDSCH or PUSCH is not started (i.e., the BWP deactivation timer is within K0/K2), the terminal device needs to perform BWP handover, which may result in interruption of data transmission.

In view of this, embodiments of the present disclosure provide a method for transmitting data, which can avoid data transmission interruption caused by BWP handover.

Fig. 2 is a schematic flow chart of a method 200 for transmitting data according to an embodiment of the present application, where the method 200 may be performed by a terminal device in the communication system 100 shown in fig. 1, and as shown in fig. 2, the method 200 may include the following steps:

s210, the terminal device determines that a first BWP deactivation timer configured on a currently activated first bandwidth part BWP times out between transmission of a control channel received on the first BWP and a data channel indicated by the control channel, or times out in the transmission process of the data channel;

s220, the terminal device starts or restarts the first BWP deactivation timer.

Generally, when the BWP deactivation timer configured on the currently activated BWP expires (or fails), the terminal device needs to perform BWP switching, that is, switching from the currently activated BWP to a default BWP or an initial BWP, in this case, if the data channel on the currently activated BWP has not been completely transmitted or has not started to be transmitted, or the data transmission on the currently activated BWP has not been completed, performing BWP switching may cause data transmission interruption.

Based on the above technical problem, in the embodiment of the present application, if a BWP deactivation timer configured on a currently activated BWP expires when a data channel has not started transmission (denoted as case 1), or expires between a received control channel and a transmission of the data channel indicated by the control channel (i.e. the data channel has not started transmission) (denoted as case 2), the terminal device starts (start) or restarts (restart) the BWP deactivation timer configured on the BWP, so that the terminal device can remain on the currently activated BWP to continue data transmission, and data transmission interruption due to BWP switching can be avoided.

It should be understood that the duration of the first BWP deactivation timer of the start or restart of the terminal device may be the same as the last time, or may also be different, for example, an initial timer duration, a default timer duration, or the like may be used, which is not limited in this embodiment of the application.

Optionally, in some embodiments, before the end device restarts the first BWP deactivation timer, the method further comprises:

the terminal device suspends BWP handover.

That is, the terminal device may suspend BWP handover in case 1 or case 2, that is, make the currently activated BWP of the terminal device still be the first BWP, and further, the terminal device may perform data channel transmission on the first BWP, so as to avoid data transmission interruption caused by BWP handover.

Optionally, in some embodiments, the data channel is a data transmission scheduled for the control channel.

For example, the data Channel is a Physical Downlink Shared Channel (PDSCH) or a Physical Uplink Shared Channel (PUSCH), and the Control Channel is a Physical Downlink Control Channel (PDCCH), that is, the PDSCH or the PUSCH may be Downlink data transmission or Uplink data transmission scheduled by the PDCCH.

Optionally, in this embodiment of the present application, the data channel is a repeated data transmission over a plurality of time units.

That is, the terminal device may repeatedly transmit the same data over multiple time units, and optionally, the time unit may be one or more time slots, one or more symbols, or the like, which is not limited in this embodiment of the present application.

Hereinafter, embodiments according to the present application will be described in detail with reference to specific examples shown in fig. 3 and 4.

For the embodiment shown in fig. 3, the terminal device may receive a PDCCH including Downlink Control Information (DCI) at a currently activated first BWP, where the DCI is used to indicate a downlink assignment (downlink assignment) or an Uplink grant (Uplink grant), that is, the DCI is used to schedule a PDSCH or a PUSCH, in which case the terminal device may start or restart a first BWP deactivation timer configured on the first BWP, and after receiving the PDCCH, the terminal device may wait to transmit the PDSCH or the PUSCH.

For case 1, if the first BWP deactivation timer expires within a time K0/K2 after the PDCCH, that is, the transmission of the PDSCH or PUSCH has not been started, or the duration of the first BWP deactivation timer is less than K0/K2, the terminal device may start or restart the first BWP deactivation timer, and continue to transmit the PDSCH or PUSCH on the first BWP, which is beneficial to avoid interruption of data transmission due to BWP handover.

For case 2, if the first BWP deactivation timer expires during the transmission of the PDSCH or PUSCH, or the duration of the first BWP deactivation timer is greater than K0/K2 and less than K0/K2+ T, where T is the transmission duration of the PDSCH or PUSCH, the terminal device may start or restart the first BWP deactivation timer, and continue to transmit the PDSCH or PUSCH on the first BWP, which is beneficial to avoiding interruption of data transmission due to BWP handover.

In the embodiment shown in fig. 4, for case 1, if the first BWP deactivation timer expires within a time K0/K2 after the PDCCH, that is, the transmission of the PDSCH or PUSCH has not started, or the duration of the first BWP deactivation timer is less than K0/K2, in this case, the terminal device may suspend BWP handover, and perform transmission of the PDSCH or PUSCH on the first BWP.

Optionally, in this embodiment, the terminal device may start or restart the first BWP deactivation timer when the PDSCH or PUSCH transmission is finished, so as to avoid interruption of data transmission due to BWP handover.

s320, when the data channel is completely transmitted, the terminal device continues or restarts the first BWP deactivation timer.

Alternatively, the time between the transmission of the control channel received on the currently activated first bandwidth portion BWP and the transmission of the data channel indicated by the control channel may be any time between the control channel and the data channel, for example, the time may be the time when the data channel starts to transmit, or may also be a certain time after the control channel and before the data channel starts to transmit, which is not limited in this embodiment of the application.

That is, the terminal device may pause the first BWP deactivation timer configured on the first BWP when the data channel starts to transmit or before the data channel starts to transmit, and then restart (restart) or continue (resume) the first BWP deactivation timer when the data channel finishes transmitting, so that it is possible to avoid interruption of data transmission due to case 1 or case 2.

It should be understood that, in the embodiment of the present application, the continuing of the first BWP deactivation timer may refer to continuing counting from the count value at which the first BWP deactivation timer is suspended, and the restarting of the first BWP deactivation timer may refer to the count value of the first BWP deactivation timer being counted again from an initial value or a default value.

It is understood that, in this embodiment, the duration of the first BWP deactivation timer may be greater than K0/K2 and less than K0/K2+ T, or the duration of the first BWP deactivation timer may also be less than K0/K2.

In this embodiment, the terminal device may suspend the first BWP deactivation timer at time t, where the time t may be the time when the PDSCH or PUSCH starts transmission, or may also be a time after the PDCCH until the PDSCH or PUSCH starts transmission, that is, the time interval between the time t and the PDCCH may be less than or equal to K0/K2.

s420, the terminal device performs BWP handover when the data channel transmission is completed.

In this embodiment of the application, in case 1 or case 2, the terminal device may not process the first BWP deactivation timer, but may suspend BWP switching, and then continue data channel transmission on the first BWP, and in case of data channel transmission completion, perform BWP switching, thereby avoiding data transmission interruption caused by BWP switching.
