[0039] It should be understood that the communication systems described in the embodiments of this application are intended to provide a clearer explanation of the technical solutions of the embodiments of this application and do not limit the technical solutions provided by the embodiments of this application. Those skilled in the art will understand that, with the evolution of system architectures and the emergence of new service scenarios, the technical solutions provided by the embodiments of this application can also be applied to similar technical challenges.

[0040] The scheduling signaling detection method provided by any one embodiment of this application may be performed alone, in combination with possible implementations of other embodiments, or in combination with any one of the related technologies.

[0041] The method and apparatus for detecting scheduling signaling provided in this application will be described in detail below with reference to the drawings.

[0042] Referring to Figure 2, Figure 2 is a schematic flowchart of a scheduling signaling detection method provided by an embodiment of the present application. The scheduling signaling detection method is performed by a terminal device. The scheduling signaling detection method includes, but is not limited to, the following steps S201 and S202.

[0043] In S201, the scheduling signaling interval is determined. In S202, the detection of scheduling signaling that schedules the same HARQ process transmission within an interval is not performed.

[0044] In the process by which network devices dynamically schedule data transmission for terminal devices, a scheduling signaling may include scheduling information for one or more time-domain units, and this scheduling information can be used to schedule data bearers for one or more time-domain units. For example, if the scheduling signaling is a downlink scheduling signaling, a terminal can schedule one time-domain unit to receive data based on the signaling. A time-domain unit can be an orthogonal frequency division multiplexing (OFDM) symbol, slot, subframe, or wireless frame, among other units.

[0045] In a process for selectively and dynamically scheduling terminal devices, terminal devices can provide feedback on their HARQ reception status to network devices. Network devices can sequentially determine idle HARQ processes, generate HARQ Process Numbers (HPNs) based on the idle HARQ processes, and include the HPNs in the scheduling signaling and send them to terminal devices. Furthermore, after receiving the scheduling signaling, terminal devices can sequentially determine, based on the HPNs in the scheduling signaling, whether to receive or transmit the channel data scheduled by the scheduling signaling in the corresponding HARQ processes.

[0046] In the embodiments of this application, in order to reduce the complexity of terminal device detection and conserve energy consumption, a single interval is determined for terminal devices, and within this interval, terminal devices do not perform detection of the same HARQ process scheduling signaling. A certain number of time-domain units must be spaced between two adjacent detections of the same HARQ process scheduling signaling by a terminal device. For example, the interval may be N subframes, or M OFDM symbols, or K slots, or L wireless frames, etc.

[0047] In embodiments of this application, a terminal device can determine the scheduling signaling interval based on protocol and / or network instructions.

[0048] Selectively, terminal devices can determine scheduling signaling intervals based on protocol agreement. In some implementations, a single candidate interval is agreed upon in the protocol, and terminal devices can choose that candidate interval as their interval.

[0049] Selectively, a terminal device can determine a scheduling signaling interval based on first instruction information. In some implementations, a first set of intervals is agreed upon in the protocol, and this first set of intervals may include one or more candidate intervals. Furthermore, a terminal device can receive first instruction information transmitted by a network device, and the terminal device can determine an interval from the first set of intervals based on the first instruction information. Selectively, the first instruction information may include an index value of a candidate interval in the first set of intervals, and the terminal device can determine the candidate interval indicated by the index value as the scheduling signaling detection interval. Selectively, the first instruction information may indicate a candidate interval in the first set of intervals via a bitmap. For example, the first instruction information may be Downlink Control Information (DCI).

[0050] Selectively, a terminal device can determine the scheduling signaling interval based on second instruction information. In some implementations, the terminal device can receive second instruction information transmitted by a network device, which may include an interval used to detect scheduling signaling set for the terminal device. The second instruction information may be, but is not limited to, radio resource control (RRC) signaling, media access control layer (MAC-CE) signaling, or other high-level signaling.

[0051] Selectively, a terminal device can determine scheduling signaling intervals based on third and fourth instruction information. In some implementations, the terminal device can receive third instruction information transmitted by a network device, which includes a second set of intervals set for the terminal device by the network device. This second set of intervals may include one or more candidate intervals. The third instruction information may be, but is not limited to, RRC signaling or MAC-CE signaling or other high-level signaling. Furthermore, the terminal device can receive fourth instruction information transmitted by the network device, and the terminal device can determine intervals from the second set of intervals based on the fourth instruction information. Selectively, the fourth instruction information may include an index value for a candidate interval in the second set of intervals, and the terminal device determines the candidate interval indicated by the index value as the scheduling signaling detection interval. Selectively, the fourth instruction information may indicate a candidate interval in the second set of intervals via a bitmap. For example, the fourth instruction information may be DCI.

[0052] In the embodiments of this disclosure, the four instructional pieces of information described above may be used individually or in combination. The first set of intervals and the second set of intervals may be the same set or different sets.

[0053] The first, second, third, and fourth instruction information may be transmitted to the terminal device by the network device via physical layer signaling. For example, the physical layer signaling may be scheduling signaling.

[0054] In embodiments of this application, a terminal device can receive physical layer signaling or high-level signaling and determine one of the first to fourth instruction information from the physical layer signaling or high-level signaling. In some implementations, one of the first to fourth instruction information can be carried in a designated information field of the physical layer signaling or high-level signaling. Correspondingly, after receiving the physical layer signaling or high-level signaling, the terminal device can obtain one of the first to fourth instruction information in the designated information field. In other implementations, one of the first to fourth instruction information can be carried in a configurable information field of the physical layer signaling or high-level signaling. Correspondingly, after receiving the physical layer signaling or high-level signaling, the terminal device can obtain one of the first to fourth instruction information in the configurable information field. The configurable information fields may be idle information fields or reusable information fields on physical layer signaling or high-layer signaling.

[0055] In the embodiments of this application, the interval set includes multiple candidate intervals. The number of bits in the information field that one of the first to fourth instruction pieces must occupy to specify a particular interval is related to the number of interval values ​​in the interval set. For example, if the interval set includes eight candidate intervals, three bits must be occupied to specify a particular interval. If the interval set includes four candidate intervals, two bits must be occupied to specify a particular interval.

[0056] Selectively, terminal devices, from the first time-domain unit in which reception of a transmission block (TB) transmitted over a physical downlink shared channel (PDSCH) has finished, move to the same HARQ process. Scheduling signaling Stop detection of the HARQ process Scheduling signaling When the terminal device reaches the second time-domain unit in which the detection is re-executed, the HARQ process Scheduling signaling The detection can be re-executed. That is, the terminal device can determine the time domain units between the second time domain unit and the first time domain unit as an interval.

[0057] The terminal device has one HARQ process called HP1 configured. As shown in Figure 3, X is the interval during which the terminal device does not perform the detection of scheduling signaling to schedule HP1 transmissions. The terminal device transmits TB1 on HP1, and after the transmission of TB1 is completed, the time domain enters interval X, and the terminal device does not perform scheduling signaling detection for HP1 within that interval X.

[0058] In the embodiments of this application, the scheduling signaling interval is determined, and the terminal device does not perform detection of scheduling signaling that schedules the same HARQ process transmission within that interval. In this application, by setting the scheduling signaling interval for the terminal device, the terminal device does not need to frequently perform detection of scheduling signaling for the same HARQ process, thereby reducing the complexity of terminal device detection, and without reducing the detection capability of the terminal device by lowering the detection frequency, it is possible to achieve both complexity and detection capability of the terminal device.

[0059] Referring to Figure 4, Figure 4 is a schematic flowchart of a scheduling signaling detection method provided by an embodiment of the present application. The scheduling signaling detection method is performed by a terminal device. The scheduling signaling detection method includes, but is not limited to, the following steps 401 to 403.

[0060] In S401, capability instruction information is reported to the network device, and this capability instruction information is used to instruct the terminal device on its data demodulation capability, which the network device uses to determine the interval.

[0061] Selectively, the data demodulation capability of a terminal device may be determined based on the hardware capabilities of the terminal device.

[0062] Selectively, terminal devices can proactively report capability information to network devices. In some implementations, terminal devices can report capability information to network devices during the initial access process. In other implementations, terminal devices can report capability information to network devices after the initial access is complete.

[0063] Selectively, a terminal device may receive request information transmitted by a network device, which is used to request the terminal device to report capability instruction information to the network device. Upon receiving such request information, the terminal device may report the capability instruction information to the network device.

[0064] In the embodiments of this application, after receiving the capability instruction information, the network device can determine the data demodulation capability of the terminal device and determine an appropriate interval for the terminal device based on that data demodulation capability. This eliminates the need for the terminal device to be detected frequently, reduces the complexity of detection, and does not reduce the detection capability of the terminal device by lowering the detection frequency.

[0065] In S402, instruction information for determining the interval, transmitted by a network device, is received.

[0066] Selectively, after a network device has determined an interval, a terminal device can receive the interval transmitted by the network device. In some implementations, the terminal device can receive signaling from the network device, which includes the interval. In other implementations, the terminal device can receive a set of intervals configured via one signaling, and further, the terminal device can receive an interval within that set of intervals indicated by another signaling. This interval is an adaptive interval determined by the network device for the terminal device based on its data demodulation capabilities.

[0067] The specific process by which a network device instructs terminal devices on the interval can be found in the relevant section of the above embodiment, so a further explanation is omitted here.

[0068] In S403, the detection of scheduling signaling that schedules the same HARQ process transmission within an interval is not performed. For a detailed explanation of step S403, please refer to the relevant descriptions in each embodiment of this application; therefore, a further explanation will be omitted here.

[0069] In the embodiments of this application, the scheduling signaling interval is determined, and the terminal device does not perform detection of scheduling signaling that schedules the same HARQ process transmission within that interval. In this application, by setting the scheduling signaling interval for the terminal device, the terminal device does not need to frequently perform detection of scheduling signaling for the same HARQ process, thereby reducing the complexity of terminal device detection, and without reducing the detection capability of the terminal device by lowering the detection frequency, it is possible to achieve both complexity and detection capability of the terminal device.

[0070] Referring to Figure 5, Figure 5 is a schematic flowchart of a scheduling signaling detection method provided by an embodiment of the present application. The scheduling signaling detection method is performed by a terminal device. The scheduling signaling detection method includes, but is not limited to, the following steps S501 to S503.

[0071] In S501, the scheduling signaling interval is determined. In S502, the detection of scheduling signaling that schedules the same HARQ process transmission within an interval is not performed.

[0072] For a detailed explanation of steps S501 to S502, please refer to the relevant descriptions in each embodiment of this application; therefore, a further explanation will be omitted here.

[0073] In S503, within the interval, detection of transmission scheduling signaling is performed for another HARQ process.

[0074] In some implementations, a terminal device may have two or more HARQ processes configured. If multiple HARQ processes are configured, the terminal device performs transmission scheduling signaling detection on the HARQ processes in a time-series manner. Within an interval, it does not repeat transmission scheduling signaling detection on the same HARQ process, but it can perform transmission scheduling signaling detection on a different HARQ process.

[0075] As an illustrative example, two HARQ processes, namely HARQ process 1 (HP1) and HARQ process 2 (HP2), may be configured for a terminal device. As shown in Figure 6, the interval at which the terminal device performs scheduling signaling detection for the same HARQ process is X. The network device transmits TB1 to the terminal device via HP1, and after receiving TB1, the terminal device must perform scheduling signaling detection for HP1 after interval X and continue to receive TB3 transmitted via HP1 in the next time-domain unit. In this example, within interval X, the terminal device can perform scheduling signaling detection for HP2 and receive TB2 transmitted via HP2.

[0076] In the embodiments of this application, the scheduling signaling interval is determined, and the terminal device can perform scheduling signaling detection for the same HARQ process transmission within the interval, while simultaneously performing scheduling signaling detection for a different HARQ process. In this application, by setting a scheduling signaling interval for the terminal device, the terminal device does not need to frequently perform scheduling signaling detection for the same HARQ process, thereby reducing the complexity of detection for the terminal device. At the same time, it is possible to achieve a balance between the complexity and detection capability of the terminal device without reducing the detection frequency and thus reducing the detection capability of the terminal device. Furthermore, within the interval, scheduling signaling detection can be performed for a different HARQ process, allowing for the normal transmission of the other HARQ process and avoiding data loss.

[0077] Referring to Figure 7, Figure 7 is a schematic flowchart of a scheduling signaling detection method provided by an embodiment of the present application. The scheduling signaling detection method is performed by a network device. The scheduling signaling detection method includes, but is not limited to, the following steps S701 and S702.

[0078] In S701, the scheduling signaling interval is determined. In S702, the terminal device is instructed to set an interval and not to perform the detection of scheduling signaling that schedules the same HARQ process transmission within that interval.

[0079] In embodiments of this application, to reduce the complexity of terminal device detection and save energy consumption, a network device can determine and instruct a terminal device on the interval of one scheduling signaling. The terminal device does not need to detect scheduling signaling for the same HARQ process within the interval.

[0080] Selectively, network devices can determine scheduling signaling intervals for terminal devices based on protocol agreement or the terminal device's data demodulation capability.

[0081] Selectively, a network device may transmit first instruction information to a terminal device, which may instruct the terminal device to determine a scheduling signaling interval from a first set of intervals agreed upon by the protocol. In some implementations, one first set of intervals may be agreed upon by the protocol, which may include one or more candidate intervals. Furthermore, the network device may transmit first instruction information to the terminal device, which may determine an interval from the first set of intervals based on the first instruction information. Selectively, the first instruction information may include an index value of a candidate interval in the first set of intervals, and the terminal device determines the candidate interval indicated by the index value as the scheduling signaling detection interval. Selectively, the first instruction information may indicate a candidate interval in the first set of intervals via a bitmap.

[0082] Selectively, a network device may determine the scheduling signaling interval based on second instruction information, and in some implementations, the network device may transmit the second instruction information to a terminal device, which may include the scheduling signaling detection interval set for the terminal device. The second instruction information may be RRC signaling, MAC-CE signaling, or other high-level signaling, but is not limited to these applications.

[0083] Selectively, a network device may instruct a terminal device on scheduling signaling intervals based on third and fourth instruction information. In some implementations, the network device may transmit third instruction information to a terminal device, which includes a second set of intervals set by the network device for the terminal device. This second set of intervals may include one or more candidate intervals. The third instruction information may be, but is not limited to, RRC signaling, MAC-CE signaling, or other high-level signaling.

[0084] Furthermore, the network device transmits a fourth instruction to the terminal device, which can then determine an interval from the second set of intervals based on the fourth instruction. Optionally, the fourth instruction may include an index value of a candidate interval in the second set of intervals, and the terminal device determines the candidate interval indicated by that index value as the interval for scheduling signaling detection. Optionally, the fourth instruction may indicate a candidate interval in the second set of intervals via a bitmap. For example, the fourth instruction may be a DCI (Digital Control Index).

[0085] Furthermore, the first, second, third, and fourth instruction information may be transmitted to the terminal device by the network device via physical layer signaling. For example, the physical layer signaling may be scheduling signaling.

[0086] In embodiments of this application, a network device can transmit physical layer signaling or high-level signaling to a terminal device, and the physical layer signaling or high-level signaling includes one of the first to fourth instructional information. In some implementations, the network device can carry one of the first to fourth instructional information in a designated information field of the physical layer signaling or high-level signaling. Correspondingly, after receiving the physical layer signaling or high-level signaling, the terminal device can obtain one of the first to fourth instructional information in the designated information field. In other implementations, the network device can carry one of the first to fourth instructional information in a configurable information field of the physical layer signaling or high-level signaling. Correspondingly, after receiving the physical layer signaling or high-level signaling, the terminal device can obtain one of the first to fourth instructional information in the configurable information field. The configurable information fields may be idle information fields or reusable information fields in scheduling signaling.

[0087] In the embodiments of this application, the interval set includes multiple candidate intervals. The number of bits in the information field that one of the first to fourth instruction pieces must occupy to specify a particular interval is related to the number of interval values ​​in the interval set. For example, if the interval set includes eight candidate intervals, three bits must be occupied to specify a particular interval. If the interval set includes four candidate intervals, two bits must be occupied to specify a particular interval.

[0088] Selectively, the network device instructs the terminal device to exit the same HARQ process from the first time-domain unit in which the reception of TB transmitted via PDSCH has finished. Scheduling signaling Stop detection of the HARQ process Scheduling signalingWhen the terminal device reaches the second time-domain unit in which the detection is re-executed, the HARQ process Scheduling signaling The time domain is re-detected. That is, the terminal device can determine the time domain unit between the second time domain unit and the first time domain unit as an interval.

[0089] The terminal device has one HARQ process called HP1 configured. As shown in Figure 3, the terminal device transmits TB1 using HP1, and after the transmission of TB1 is completed, the time domain enters an interval, and within that interval, the terminal device does not perform scheduling signaling detection for HP1.

[0090] In the embodiments of this application, by determining the scheduling signaling interval and instructing the terminal device, the terminal device does not perform the detection of scheduling signaling that schedules the same HARQ process transmission within the interval. In this application, by setting the scheduling signaling interval for the terminal device, the terminal device does not need to frequently perform the detection of scheduling signaling for the same HARQ process, thereby reducing the complexity of terminal device detection, and without reducing the detection capability of the terminal device by lowering the detection frequency, it is possible to achieve both complexity and detection capability of the terminal device.

[0091] Referring to Figure 8, Figure 8 is a schematic flowchart of a scheduling signaling detection method provided by an embodiment of the present application.

[0093] Selectively, the data demodulation capability of a terminal device may be determined based on the hardware capabilities of the terminal device.

[0094] Selectively, network devices can receive capability information proactively reported by terminal devices. In some implementations, network devices can receive capability information reported by terminal devices during the initial access process. In other implementations, network devices can receive capability information reported by terminal devices after the initial access is complete.

[0095] Selectively, a network device may send request information to a terminal device, which is used to request the terminal device to report capability instruction information to the network device. Furthermore, upon receiving such request information, the terminal device may report capability instruction information to the network device. In response, the network device may receive the capability instruction information reported by the terminal device based on the request information.

[0096] In the embodiments of this application, after a network device receives the capability instruction information, it can determine the data demodulation capability of a terminal device, and further determine an appropriate interval for the terminal device based on that data demodulation capability. This eliminates the need for the terminal device to perform detection frequently, reduces the complexity of detection, and does not degrade the detection capability of the terminal device by lowering the detection frequency.

[0097] In S803, the terminal device is instructed to set an interval and not to perform the detection of scheduling signaling that schedules the same HARQ process transmission within that interval.

[0098] For a detailed explanation of step S803, please refer to the relevant descriptions in each embodiment of this application; therefore, a further explanation will be omitted here.
