Obviously, the described embodiments are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present disclosure.

The technical solutions provided by the embodiments of the present disclosure can be applied to various systems, especially 5G systems. For example, the applicable system may be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet Wireless business (general packet radio service, GPRS) system, long term evolution (long term evolution, LTE) system, LTE frequency division duplex (frequency division duplex, FDD) system, LTE time division duplex (time division duplex, TDD) system, Long term evolution advanced (LTE-A) system, universal mobile telecommunications system (UMTS), worldwide interoperability for microwave access (WiMAX) system, 5G new air interface (New Radio, NR) system, etc. These various systems include end devices and network devices. The system may also include a core network part, such as an evolved packet system (Evloved Packet System, EPS), a 5G system (5GS), and the like.

First introduce the following:

(1) Repeated transmission of uplink data;

Figure 1 is a schematic diagram of an uplink data transmission process provided by an embodiment of the disclosure, and Figure 2 is a schematic diagram of an uplink repeated transmission process provided by an embodiment of the disclosure, as shown in Figures 1 and 2, uplink data transmission is divided into configuration scheduling or free Scheduling or predefined scheduling (Configured Grant, CG) and dynamic scheduling (Dynamic Grant, DG) in two ways, where CG is divided into Type1CG and Type2CG. When the terminal, also known as user equipment, (User Equipment, UE) detects that rrc-ConfiguredUplinkGrant is included in the transmission parameter configuredGrantConfig configured by the upper layer, it determines that the CG type is Type1CG, and it can be sent according to the time-frequency resource and the number of repeated transmissions predefined by the upper layer Uplink data; when the transmission parameter configuredGrantConfig configured by the upper layer does not include rrc-ConfiguredUplinkGrant, it is judged that the CG type is Type 2CG, and the configuration information of Type 2CG is configured by the upper layer signaling and PDCCH and used after DCI activation, and scrambled by CS-RNTI Schedule downlink control information (Downlink control Information, DCI) (0-0 or 0-1 or 0-2) to activate configurations such as time-frequency resource locations for uplink transmission, and the configuration parameters take effect periodically until the UE successfully receives the deactivation signaling. DG transmission uses Cell-RadioNetworkTemporaryIdentifier (C-RNTI) scrambling and scheduling DCI (0-0 or 0-1 or 0-2) to indicate configuration information such as the time-frequency resource location of the UE's current uplink data transmission. In Type2CG and DG transmission, if the time domain resource assignment (TDRA) table indicated by DCI contains the number of repeated transmissions, the configuration in the TDRA table is used, and if the number of repeated transmissions is not included in the TDRA table, wireless resources are used Control (Radio Resource Control, RRC) semi-static configuration of the number of repeated transmission configuration parameters; otherwise, the number of repeated transmissions is 1.

In Type 1 or Type 2 CG data transmission, the UE repeats the same PUSCH sequentially according to the indicated number of repeated transmissions. If the retransmission schedule of the same PUSCH is not received within the CGT time after the transmission is completed, the base station judges that the reception is correct; for DG, every An uplink data transmission (new transmission or retransmission) needs to wait until DCI scheduling to start;

(2) Repeated transmission of downlink data;

Figure 3 is a schematic diagram of the downlink repeated transmission process provided by the embodiment of the present disclosure. As shown in Figure 3, similar to the uplink data repeated transmission process, the downlink transmission is divided into Semi-Persistent Scheduling (Semi-Persistent Scheduling, SPS) and DG (Dynamic Grant ) in two ways; SPS configuration information is jointly configured by high-level signaling and Physical downlink control channel (PDCCH) and used after activation by DCI; DG is the configuration information carried by DCI for one transmission; UE receives Feedback ACK or NACK in a specific time slot (slot) after the repeated transmission of the PDSCH (for example, the higher layer configuration parameter dl-DataToUL-ACK, PDSCH-to-HARQ_feedback timing indicator field values in DCI).

In CG or Semi-Persistent Scheduling (Semi-Persistent Scheduling, SPS) and DG configurations, the number of available multi-configurations is limited and the flexibility of data packet repetition configuration is limited. Therefore, when applied to XR multi-stream services, when the data packet size and reliability requirements for different data streams are different, there will be a problem of waste of resources for data streams with low reliability requirements; especially in CG or SPS, repeated transmission The number of times is periodic or the activation period takes effect. When the number of repeated transmissions is configured to be higher than the actual number of repeated transmissions required, the termination indication information applied to DG may not be applicable to CG or SPS;

In XR multi-stream service transmission, different data streams have different priorities. When the current data has not been transmitted, there are high-priority or delay-demanding services that need to be transmitted. Signaling is required to instruct the terminal to start a new service for the current service. business;

XR service coverage can be improved through uplink or downlink repeated transmission. When transmitting uplink or downlink data in the repeated transmission process in the communication system, the number of optional repeated transmissions is limited. This will cause the problem that the base station or terminal cannot flexibly adjust the number of repeated transmissions in terms of resource scheduling and utilization, which will also lead to waiting delays for new data packets;

Therefore, the embodiments of the present disclosure provide a method and device for terminating data transmission, so as to improve resource utilization while ensuring correct data reception.

Among them, the method and the device are conceived based on the same application. Since the principle of solving problems of the method and the device is similar, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated.

When receiving downlink data, the terminal device may determine that the first data is received correctly when receiving K2<K1 transmissions, and then select the nearest sending candidate position to send the termination indication information. The network device detects the termination indication information at the candidate position for sending the termination indication information, and terminates the repeated transmission of the first data after the indication information takes effect.

The network side detects the termination indication information at the receiving position of the termination indication information in the middle of sending the first data, and once the termination indication information is heard, it immediately stops the subsequent repeated transmission of the first data; if there is new downlink data to be transmitted subsequently, it sends a new Data indicates DCI, otherwise, nothing is indicated.

If the network side does not detect the termination indication information sent by the terminal, but there is a more urgent service to be transmitted at this time, send the scheduling DCI after the second data ends, terminate the terminal receiving the first data and start receiving the second data;

If it is SPS, you can enable the effective duration (duration=T slots, T=0, 1, 2, 3...). During the continuous effective time, according to the actual number of repeated transmissions of the first data before the termination of transmission, in the current SPS Send new data on the preconfigured location. Wherein, in order to ensure rapid detection and validation of the termination indication information, the time domain duration of the candidate location may be set to no more than 2symbols. If a deactivation signaling is received within the duration, the effective duration is invalid.

If the terminal does not judge in advance that the first data is received correctly, but receives a new data reception signaling in the middle of receiving the first data, it can receive the new downlink data according to the instructions after the signaling takes effect, and receive the previous data according to the signaling. Feedback ACK or NACK for the received downlink data.

In order to ensure that the termination indication information is quickly detected and takes effect, the time domain duration of the pre-configured DL symbol that terminates the uplink data transmission in advance can be detected not to exceed 2symbols. If DCI is used to carry the termination indication information, see Table 1 and Table 2 for the parameter configuration of the search space. If the termination instruction information is carried by sequence, the optional location of the sending on the network side and the receiving of the terminal device refers to the DCI-based configuration search space location configuration;

The embodiments of the present disclosure are applicable to uRLLC and eMBB services in addition to XR services. In the prior art, only DCI2-4 can terminate a PUSCH transmission in advance (Time duration=a slot) when uRLLC and eMBB services conflict, but XR The data packet is relatively large (e.g. average packet size=62.5k bytes) and both uplink and downlink exist. Embodiments of the present disclosure can also be used to solve the problem of collision with the uplink or downlink of the XR service and the problem of emergency service transmission.
