The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those with ordinary skill in the art without making progressive improvements shall fall within the scope of protection of the present invention.

The technical solutions provided by the embodiments of the present invention can be applied to a variety of systems, especially 5G systems. For example, applicable systems may be global system of mobile communication (GSM) system, code division multiple access (code division multiple access, CDMA) system, wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) General packet radio service (GPRS) system, long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) ) system, long term evolution advanced (LTE-A) system, universal mobile telecommunication system (UMTS), worldwide interoperability for microwave access (WiMAX) system, 5G new Air interface (New Radio, NR) system, etc. These various systems include terminal equipment and network equipment. The system can also include core network parts, such as the Evolved Packet System (EPS), 5G system (5GS), etc.

First, the following content is introduced: (1) Uplink data repeated transmission; Figure 1 is a schematic diagram of the uplink data transmission process provided by an embodiment of the present invention, and Figure 2 is a schematic diagram of the uplink repeated transmission process provided by an embodiment of the present invention, as shown in Figure 1 As shown in Figure 2, uplink data transmission is divided into two methods: configured scheduling or scheduling-free or predefined scheduling (Configured Grant, CG) and dynamic scheduling (Dynamic Grant, DG). CG is divided into Type1 CG and Type2 CG. When the terminal, also known as user equipment (UE), detects that the transmission parameter configuredGrantConfig configured by the higher layer includes rrc-ConfiguredUplinkGrant, it determines that the CG type is Type1 CG, and can transmit it repeatedly according to the time-frequency resources predefined by the higher layer. number of times to send uplink data; when the high-level configured transmission parameter configuredGrantConfig does not include rrc-ConfiguredUplinkGrant, the CG type is judged to be Type 2 CG. The configuration information of Type 2 CG is composed of high-level signaling and physical downlink control channel (Physical downlink control channel, PDCCH) Commonly configured and used after DCI is started, the CS-RNTI scrambling schedule is used to schedule the downlink control information (DCI) (0-0 or 0-1 or 0-2) to start uplink transmission time and frequency resource location and other configurations. Configuration The parameters take effect periodically until the UE successfully receives the deactivation signaling. DG transmission uses Cell-Radio Network Temporary Identifier (C-RNTI) scrambling and scheduling DCI (0-0 or 0-1 or 0-2) to indicate the time-frequency resource location of the UE's current uplink data transmission. and other configuration information. In Type2 CG 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. If the TDRA table does not contain the number of repeated transmissions, the wireless Resource Control (Radio Resource Control, RRC) semi-static configuration of the number of repeated transmission configuration parameters; otherwise, the number of repeated transmissions is 1.

During Type 1 or Type 2 CG data transmission, the UE repeatedly transmits the same PUSCH in sequence 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, it is judged that the base station received it correctly; for DG , each uplink data transmission (new transmission or retransmission) needs to wait until DCI scheduling before it can be started; (2) Downlink data is repeatedly transmitted; Figure 3 is a schematic diagram of the downlink repeated transmission process provided by the embodiment of the present invention, as shown in Figure 3. Similar to the uplink data repeated transmission process, downlink transmission is divided into two methods: Semi-Persistent Scheduling (SPS) and DG (Dynamic Grant, dynamic scheduling); the configuration information of SPS is composed of high-level signaling and entity downlink control channels (Physical downlink control channel, PDCCH) is co-configured and used after DCI is started; DG is the configuration information carried by DCI for one transmission; the UE is specific after receiving the repeatedly transmitted PDSCH (for example, the high-level configuration parameter dl-DataToUL-ACK , ACK or NACK is fed back in the time slot (slot) of PDSCH-to-HARQ_feedback timing indicator field values) in DCI.

In CG or Semi-Persistent Scheduling (SPS) and DG configurations, the number of available multiple configurations is limited and the flexibility of configuring the number of repetitions of data packets is limited. Therefore, when applied to XR multi-stream services, if the packet size and reliability requirements of different data streams are different, there will be a problem of resource waste for data streams with low reliability requirements; especially in CG or SPS, the number of repeated transmissions takes effect periodically or during the startup period. When the number of repeated transmissions is configured to be higher than the actual required number of repeated transmissions, 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 is not transmitted, services with high priority or more stringent latency requirements need to be transmitted, and signaling is required to instruct the terminal current service to start a new service; XR service coverage can be improved through uplink or downlink repeated transmission. When uplink or downlink data is transmitted in the repeated transmission process in the communication system, the number of optional repeated transmissions is limited. This will cause the base station or terminal to be unable to flexibly adjust the number of repeated transmissions in resource scheduling and utilization, which will also cause a waiting delay for new data packets; therefore, an embodiment of the present invention provides a method and device for terminating data transmission to improve resource utilization while ensuring correct data reception.

Among them, the method and the device are based on the same application concept. Since the principles of solving the problem by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repetitions will not be repeated.

FIG4 is one of the flowcharts of the method for terminating data transmission provided by an embodiment of the present invention.

When the terminal device detects the termination indication information at a signaling receiving position in the middle of the transmitted data, the current PUSCH repeated transmission can be terminated immediately.

For example, the first communication device is a network device, and the second communication device is a terminal. After receiving k0 (k0 < K, K is the total number of repeated transmissions of the first data) times of the first data, the network device can enter a specific state through event judgment, and send a termination indication message carrying a second data transmission indication.

After the network device receives the feedback that the terminal device has received the correct message, it sends a new scheduled DCI to indicate the new PDSCH transmission. The terminal device receives the new instruction and stops subsequent Receive feedback at the location to receive the correct first data PDSCH, and receive new PDSCH, which is the second data, at the location indicated by the new instruction; wherein, the terminal equipment determines the downlink by requesting the scheduled DCI or SPS initiated DCI signaling fed back by the network equipment after scheduling. The number of data retransmissions K1 and the receiving position. When the terminal device determines that the reception is correct after receiving K2 (K2 is the actual number of retransmissions, K1 is the total number of retransmissions configured, K2 <K1) first data, the closest termination The instruction information sending position reports the ACK information and does not receive the current first data at the subsequent position.

During the validity period, the actual number of PUSCH repeated transmissions when it takes effect can be received according to the termination instruction information in Type1 CG preconfiguration or Type2 New data is sent at the transfer location initiated by the CG. If the base station scheduling (new transmission or retransmission) signaling is received within the effective duration, the scheduled transmission signaling will not be affected by the effective time.

In order to ensure that the termination indication information is quickly detected and effective, the time domain duration of the preconfigured DL symbol that terminates uplink data transmission in advance can be detected not to exceed 2 symbols. 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 indication information is carried in a sequence, the network side sending and the terminal device receiving optional locations refer to the DCI-based configuration search space location configuration; after the terminal device starts transmission, it can detect the termination indication information on the dedicated transmission resource. When the termination is detected indication information, and after the effective time of the termination indication information is met, the uplink data transmission can be repeated after the termination indication information takes effect or the transmission of new data, that is, the second data, can be started while terminating the current transmission.

In one embodiment, if the first communication device is a terminal, the second communication device can be a network device, such as a base station, and the first data is downlink data; the terminal device can obtain the configuration parameters of the downlink data, i.e., the first data transmission; wherein, the first data transmission configuration parameters are obtained in the following manner: the transmission information includes: the number of repetitions K1 of the first data PDSCH transmission this time and the time domain position of the transmission; wherein K1 is carried in the scheduling PDSCH DCI or SPS activation DCI information domain.

The terminal device can enter a specific state by judging an event, such as judging that the first data has been correctly received in advance. If the terminal device can support the sending of termination indication information for terminating uplink data transmission in advance, the candidate positions for sending the termination indication information can be configured. Sending the termination indication information at these positions indicates that the downlink data is correctly received in advance. When the terminal supports the sending of termination indication information for terminating downlink data transmission in advance, the high layer can configure exclusive candidate position information (i.e., as a dedicated transmission resource) for the terminal sending and the network side receiving of this termination indication information in the repetition data transmission, including: the number of candidate positions ({1, 2, 3..... }), the number of symbols for a single candidate position (not exceeding 2 symbols), and the time domain position. The number of configurations of this parameter is consistent with the number of candidate positions). When the terminal device supports sending termination indication information, it feeds back the ACK information for the current transmission (as termination indication information) at this configuration location.

When receiving downlink data, the terminal device can determine that the first data has been received correctly after receiving K2<K1 transmissions, and then selects the nearest sending candidate location to send the termination indication information. The network device detects the termination indication information at the sending termination indication information detection candidate position, 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 termination indication information receiving position in the middle of sending the first data, and once the termination indication information is monitored, the subsequent repeated transmission of the first data is immediately stopped; if there is new downlink data to be transmitted subsequently, NDI is issued, otherwise, no indication is given.

If the network side does not detect the termination instruction information sent by the terminal, but there are more urgent services that need to be transmitted at this time, the scheduling DCI after the end of the second data is issued, and the terminal terminates the reception of the first data and starts receiving the second data; if it is SPS , you can enable the validity duration (duration=T slots, T=0, 1, 2, 3...). During the duration of validity, according to the actual number of repeated transmissions of the first data before terminating the transmission, the current SPS schedule Send new data at the configured location. Among them, in order to ensure the rapid detection and effectiveness of the termination indication information, the time domain duration of the candidate position can be set to no more than 2 symbols. If deactivation signaling is received within the duration, the effective duration is invalid.

If the terminal does not determine in advance that the first data is received correctly, but receives new data reception signaling while receiving the first data, it can receive new downlink data as instructed after the signaling takes effect, and feedback ACK or NACK (negative acknowledgment) based on the downlink data reception status before the signaling is received.

In order to ensure that the termination indication information is quickly detected and effective, the time domain duration of the preconfigured DL symbol that terminates uplink data transmission in advance can be detected not to exceed 2 symbols. 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 indication information is carried in a sequence, the network side sending and the terminal device receiving optional locations refer to the DCI-based configuration search space location configuration; after the terminal device starts transmission, it can detect the termination indication information on the dedicated transmission resource. When the termination is detected indication information, and after the effective time of the termination indication information is met, the uplink data transmission can be repeated after the termination indication information takes effect or the transmission of new data, that is, the second data, can be started while terminating the current transmission.

In addition to being applicable to XR services, the embodiments of the present invention are also applicable to uRLLC (Ultra-Reliable and Low Latency Communications) and eMBB (Enhanced Mobile Broadband) services. In the existing technology, only DCI2-4 can terminate a PUSCH transmission in advance (Time duration = a slot) when uRLLC and eMBB services conflict. However, XR data packets are relatively large (e.g. average packet size = 62.5k bytes) and exist in both uplink and downlink. The embodiments of the present invention can also be used to solve the collision problem with the uplink or downlink of XR services and the transmission problem of emergency services.
