The character "/" generally indicates that the context-dependent object is an "or" relationship.
The term "plurality" in the embodiments of the present application means two or more, and other adjectives are similar thereto.
The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The technical scheme provided by the embodiment of the application can be suitable for various systems, in particular to a 5G system. For example, suitable systems may be global system for mobile communications (global system of mobile communication, GSM), code division multiple access (code division multiple access, CDMA), wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) universal packet Radio service (general packet Radio service, GPRS), long term evolution (long term evolution, LTE), LTE frequency division duplex (frequency division duplex, FDD), LTE time division duplex (time division duplex, TDD), long term evolution-advanced (long term evolution advanced, LTE-a), universal mobile system (universal mobile telecommunication system, UMTS), worldwide interoperability for microwave access (worldwide interoperability for microwave access, wiMAX), 5G New air interface (New Radio, NR), and the like. Terminal devices and network devices are included in these various systems. Core network parts such as evolved packet system (Evloved Packet System, EPS), 5G system (5 GS) etc. may also be included in the system.
The following will be described first:
(1) Repeating uplink data transmission;
fig. 1 is a schematic diagram of an uplink data transmission flow provided in an embodiment of the present application, and fig. 2 is a schematic diagram of an uplink repeated transmission flow provided in an embodiment of the present application, where, as shown in fig. 1 and fig. 2, uplink data transmission is divided into two modes of Configured scheduling or non-scheduled or predefined scheduling (CG) and Dynamic scheduling (DG), where CG is further divided into Type1 CG and Type2 CG. When a terminal, also called User Equipment (UE), detects that a transmission parameter configurable grant of a higher layer configuration includes a rrc-configurable uplink grant, determining that the CG Type is Type1 CG, and sending uplink data according to a predefined time-frequency resource and a repeated transmission number of times of the higher layer; when the transmission parameter configurable GrantConfig of the high-level configuration does not comprise rrc-configurable uplink grant, judging that the CG Type is Type2 CG, wherein the configuration information of the Type2 CG is jointly configured by the high-level signaling and PDCCH and is used after being activated by DCI, and the configuration such as the position of uplink transmission time-frequency resources is activated by CS-RNTI scrambling and scheduling downlink control information (Downlink control Information, DCI) (0-0 or 0-1 or 0-2), and the configuration parameters are periodically validated until the UE successfully receives the deactivation signaling. And when DG is transmitted, the DCI (0-0 or 0-1 or 0-2) is subjected to scrambling scheduling through a Cell-radio network temporary identifier (C-RNTI) to indicate configuration information such as the time-frequency resource position of the uplink data transmission of the UE. In Type2 CG and DG transmission, if the time domain resource allocation (time domain resource assignment, TDRA) table indicated by DCI contains the number of retransmissions, using the configuration in the TDRA table, if the TDRA table does not contain the number of retransmissions, using the configuration parameters of the number of retransmissions of the radio resource control (Radio Resource Control, RRC) semi-static configuration; otherwise, the number of repeated transmissions is 1.
In Type 1 or Type 2 CG data transmission, the UE sequentially and repeatedly transmits the same PUSCH according to the indicated repeated transmission times, and judges that the base station receives correctly if retransmission scheduling of the same PUSCH is not received in CGT time after transmission is completed; for DG, each uplink data transmission (new transmission or retransmission) needs to wait until DCI scheduling can be started;
(2) Repeating transmission of downlink data;
fig. 3 is a schematic diagram of a downlink retransmission process provided in the embodiment of the present application, as shown in fig. 3, similar to an uplink retransmission process, downlink transmission is divided into two modes, i.e., semi-persistent scheduling (Semi-Persistent Scheduling, SPS) and DG (Dynamic Grant); the configuration information of the SPS is jointly configured by a high-layer signaling and a physical downlink control channel (Physical downlink control channel, PDCCH) and is used after being activated by DCI; DG is configuration information carried by DCI for one transmission; the UE feeds back ACK or NACK in a slot (slot) of a specific (e.g., higher layer configuration parameter dl-DataToUL-ACK, PDSCH-to-harq_ feedback timing indicator field values in DCI) after receiving the repeatedly transmitted PDSCH.
CG or Semi-persistent scheduling (Semi-Persistent Scheduling, SPS) and DG configurations, the number of available multiple configurations is limited and the flexibility of the configuration of the number of repetitions of the packet is limited. Therefore, when the method is applied to XR multi-stream service and the data packet sizes and reliability requirements for different data streams are different, the problem of resource waste exists for the data stream with low reliability requirements; particularly in CG or SPS, the number of retransmissions is periodic or the active period is in effect, and when the number of retransmissions is configured to be higher than the number of retransmissions actually required, the termination indication information applied to DG is not necessarily applicable to CG or SPS;
In XR multi-stream service transmission, different data streams have different priorities, when the current data is not transmitted, the service with higher priority or more severe time delay requirement reaches the requirement of transmission, and the signaling is required to instruct the terminal to start new service for the current service;
the XR service coverage can be improved by uplink or downlink retransmission, and the number of optional retransmission is limited when uplink or downlink data is transmitted in the retransmission flow in the communication system. The problem that the base station or the terminal cannot flexibly adjust the repeated transmission times in the aspects of resource scheduling and utilization exists, and the problem also causes the waiting time delay of a new data packet;
therefore, the embodiment of the application provides a method and a device for terminating data transmission, which are used for improving the resource utilization rate under the condition of ensuring correct data reception.
The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.
Fig. 4 is one of flow diagrams of a method for terminating data transmission according to an embodiment of the present application, and as shown in fig. 4, an embodiment of the present application provides a method for terminating data transmission, where an execution body of the method may be a first communication device, and the first communication device may be a transmitting end of termination indication information, for example, may be a terminal or a base station. The method comprises the following steps:

And transmitting the second data, wherein the transmission priority of the second data is higher than that of the first data.
Specifically, when uplink or downlink repeated transmission needs to be considered, under the condition of ensuring the receiving performance, unnecessary uplink or downlink repeated data transmission is reduced, or more urgent uplink or downlink service transmission needs exist, the current data transmission can be interrupted.

In one embodiment, if the first communication device is a network device, such as a base station, the second communication device may be a terminal, and the first data is uplink data;
the terminal equipment can acquire configuration parameters of uplink data, namely first data transmission, and start repeated transmission of the first data;
the first data transmission configuration parameter obtaining mode is as follows:
the terminal equipment reads TDRA information (including the position of a frequency domain during uplink data transmission, the mapping Type and the like) from CS-RNTI or C-RNTI scrambled scheduling DCI (DCI 0-0 or 0-1 or 0-2), and looks up the table to obtain the repeated transmission times K of the current transmission TB, and if the TDRA table does not contain the information of K, the K is determined through a high-level configuration parameter;
The network device may enter a specific state through a decision event, for example, it is determined that the first data has received new data, i.e., the second data, which is correct or has been transmitted in an emergency, if the terminal device may support receiving termination indication information for terminating uplink data transmission in advance, the termination indication information may be carried by DCI or may be carried by a specific sequence (i.e., the first sequence) or the first sequence may be combined with DCI; the network device configures a search space for the termination instruction information in advance (the termination instruction information carried by the sequence can also be mapped on the SS), when receiving the uplink data, and when receiving K0 times of transmission (K0 < the current repeated transmission times K), judging to enter a specific state (for example, judging to receive correct in advance or new data of urgent transmission exists), and then transmitting termination instruction information for terminating the uplink data transmission in advance at a termination instruction information transmitting position closest to the network device.
The duration of the validity may be defined (duration=n slots, n=1, 2,3 …), and new data may be sent at a transmission position preconfigured by Type1 CG or activated by Type2 CG according to the actual PUSCH repetition transmission number when the termination indication information is received and validated in the validity time. If the base station scheduling (new or retransmitted) signaling is received within the validation duration, the scheduled transmission signaling is not affected by the validation time.
In order to ensure the rapid detection and validation of the termination indication information, it is possible to detect that the time domain duration of the pre-configured DL symbols for early termination of uplink data transmission does not exceed 2 symbols. If DCI is adopted to bear the termination indication information, the parameter configuration of the search space is shown in Table1 and Table2. If the termination indication information adopts sequence bearing, the network side sends and the terminal equipment receives optional position reference DCI-based configuration search space position configuration;
after starting transmission, the terminal device can detect the termination instruction information on the dedicated transmission resource, and when the termination instruction information is detected and the effective time of the termination instruction information is satisfied, the terminal device can start new data, namely, the transmission of second data, according to repeated uplink data transmission after the effective time of the termination instruction information or while stopping the current transmission.

The terminal device may enter a specific state through a decision event, for example, it is determined that the first data has been received correctly in advance, and if the terminal device may support transmission of termination indication information for terminating uplink data transmission in advance, the candidate positions for transmission may be configured for the termination indication information, and the transmission of the termination indication information at these positions indicates that downlink data has been received correctly in advance;
when the terminal supports the transmission of termination indication information for terminating the downlink data transmission in advance, the higher layer may configure dedicated candidate location information (i.e. as dedicated transmission resources) in the middle of the repetition data transmission for the transmission of the terminal and the reception of the network side of the termination indication information, including: number of candidate positions ({ 1,2,3 … }), number of single candidate position duration symbols (not more than 2 symbols), time domain position, number of configuration of this parameter is consistent with the number of candidate positions, and ACK information for current transmission (as termination instruction information) is fed back on this configuration position when the terminal device supports transmission of termination instruction information.
When the terminal equipment receives downlink data, and when K2< K1 times of transmission are received, the terminal equipment can judge that the first data is received correctly, and select the nearest transmission candidate position to transmit termination indication information. The network device detects the termination instruction information at the position of the detection candidate of the transmission termination instruction information, and the repeated transmission of the first data after the termination instruction information is validated.
The network side detects termination indication information at a termination indication information receiving position in the middle of sending the first data, and immediately stops repeated transmission of the subsequent first data once the termination indication information is monitored; and if new downlink data is required to be transmitted subsequently, issuing new data to indicate DCI, otherwise, not making any indication.
If the network side does not detect the termination indication information sent by the terminal, but more urgent service needs to be transmitted at the moment, the scheduling DCI after the second data is sent is finished, and the terminal is terminated to receive the first data and starts to receive the second data;
in the case of SPS, the duration of the validity (duration=tslots, t=0, 1,2,3, …) may be turned on, and new data may be sent at the current SPS preconfigured location for the duration of validity according to the actual number of repetitions of the first data before terminating the transmission. In order to ensure that the termination indication information is detected and validated quickly, the time domain duration of the candidate position may be set to not more than 2 symbols. If deactivation signaling is received within the duration, the validation duration is not valid.
If the terminal does not judge that the first data is received correctly in advance, but receives a new data receiving signaling in the middle of receiving the first data, the terminal can receive new downlink data according to the indication after the signaling is effective, and feeds back ACK or NACK according to the downlink data receiving condition before the signaling is received.
In order to ensure the rapid detection and validation of the termination indication information, it is possible to detect that the time domain duration of the pre-configured DL symbols for early termination of uplink data transmission does not exceed 2 symbols. If DCI is adopted to bear the termination indication information, the parameter configuration of the search space is shown in Table1 and Table2. If the termination indication information adopts sequence bearing, the network side sends and the terminal equipment receives optional position reference DCI-based configuration search space position configuration;
after starting transmission, the terminal device can detect the termination instruction information on the dedicated transmission resource, and when the termination instruction information is detected and the effective time of the termination instruction information is satisfied, the terminal device can start new data, namely, the transmission of second data, according to repeated uplink data transmission after the effective time of the termination instruction information or while stopping the current transmission.
In addition to being applicable to XR service and being applicable to ul lc and eMBB service, in the prior art, only DCI2-4 may terminate PUSCH transmission once in advance (Time duration=a slot) when ul lc and eMBB service collide, but the XR data packet is relatively large (e.g. average packet size=62.5 k bytes) and exists in both uplink and downlink directions, and the embodiment of the present invention may also be used to solve the problem of collision with XR service uplink or downlink and the problem of emergency service transmission.
