[0033] To better understand the scheduling signaling detection method disclosed in the embodiments of the present application, a communication system to which the embodiments of the present application are applicable will first be described below.

[0034] Referring to FIG. 1, FIG. 1 is a schematic diagram of the architecture of a communication system provided by an embodiment of the present application.

It should be noted that the sidelink in the embodiments of the present application may also be referred to as a sidelink or a direct communication link.

[0036] The network device 101 in the embodiments of the present application is a network-side entity used to transmit or receive signals. For example, the network device 101 may be an evolved base station (eNB), a transmission reception point (TRP), a next-generation base station (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system.

The network device provided by the embodiments of the present application may be configured with a centralized unit (CU) and distributed units (DUs). The CU may also be referred to as a control unit. The CU-DU configuration is used to separate protocol layers of a network device, for example, a base station, with some protocol layer functions centrally controlled by the CU and the remaining or all protocol layer functions distributed to the DUs, and the DUs are centrally controlled by the CU.

[0039] It should be understood that the communication system described in the embodiments of the present application is intended to more clearly explain the technical solutions of the embodiments of the present application, and does not limit the technical solutions provided by the embodiments of the present application. Those skilled in the art can understand that with the evolution of system architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present application can also be applied to similar technical problems.

[0040] It should be noted that the scheduling signaling detection method provided by any one of the embodiments of the present application may be performed alone, or may be performed in combination with possible implementation methods of other embodiments, or may be performed in combination with any one of the technical solutions of the related art.

[0041] Hereinafter, the scheduling signaling detection method and apparatus provided by the present application will be described in detail 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 interval of the scheduling signaling is determined. In S202, detection of scheduling signaling that schedules transmission of the same HARQ process is not performed within the interval.

[0044] In a process in which a network device dynamically schedules data transmission of a terminal device, one scheduling signal may include scheduling information for one or more time domain units, and the scheduling information may be used to schedule data bearers for one or more time domain units. For example, if the scheduling signal is downlink scheduling signaling, the terminal may schedule one time domain unit to receive data based on the scheduling signal. The time domain unit may be an Orthogonal Frequency Division Multiplexing (OFDM) symbol, a slot, a subframe, a radio frame, or the like.

[0045] Optionally, in the process of dynamically scheduling the terminal device, the terminal device can feed back HARQ reception status to the network device. The network device can sequentially determine idle HARQ processes, generate HARQ process numbers (HPNs) based on the idle HARQ processes, and include the HPNs in scheduling signaling to send to the terminal device. Furthermore, after receiving the scheduling signaling, the terminal device sequentially determines, based on the HPNs in the scheduling signaling, to receive or transmit channel data scheduled by the scheduling signaling through the corresponding HARQ processes.

[0046] In an embodiment of the present application, to reduce the detection complexity of a terminal device and save energy consumption, an interval is determined for the terminal device, and within the interval, the terminal device does not perform detection of scheduling signaling for the same HARQ process. Between two adjacent detections of scheduling signaling for the same HARQ process by the terminal device, an interval of a certain number of time domain units is required. For example, the interval may be N subframes, M OFDM symbols, K slots, or L radio frames.

[0047] In an embodiment of the present application, the terminal device may determine the interval of the scheduling signaling based on a protocol and / or a network instruction.

[0048] Alternatively, the terminal device may determine the interval of the scheduling signaling based on a protocol agreement. In some implementations, a candidate interval is agreed upon in the protocol, and the terminal device may determine the candidate interval as the interval.

[0049] Optionally, the terminal device can determine the interval of the scheduling signaling based on the first indication information. In some implementations, a protocol agrees on a first interval set, and the first interval set can include one or more candidate intervals. Furthermore, the terminal device can receive first indication information transmitted by the network device, and the terminal device can determine an interval from the first interval set based on the first indication information. Optionally, the first indication information includes an index value of a candidate interval in the first interval set, and the terminal device can determine the candidate interval indicated by the index value as the interval for detecting the scheduling signaling. Optionally, the first indication information can indicate a candidate interval in the first interval set via a bitmap. For example, the first indication information may be downlink control information (DCI).

[0050] Alternatively, the terminal device may determine an interval for the scheduling signaling based on second indication information. In some implementations, the terminal device may receive second indication information sent by the network device, and the second indication information may include an interval for detecting the scheduling signaling configured for the terminal device. Note that the second indication information may be Radio Resource Control (RRC) signaling, Media Access Control-Control Element (MAC-CE) signaling, or other higher layer signaling, but this application is not limited to this.

[0051] Optionally, the terminal device can determine the interval of the scheduling signaling based on the third indication information and the fourth indication information. In some implementations, the terminal device can receive third indication information transmitted by the network device, the third indication information including a second interval set configured for the terminal device by the network device. The second interval set can include one or more candidate intervals. The third indication information may be RRC signaling, MAC-CE signaling, or other higher layer signaling, but is not limited to this in the present application. Furthermore, the terminal device can receive fourth indication information transmitted by the network device, and the terminal device can determine an interval from the second interval set based on the fourth indication information. Optionally, the fourth indication information can include an index value of a candidate interval in the second interval set, and the terminal device determines the candidate interval indicated by the index value as the interval for detecting the scheduling signaling. Optionally, the fourth indication information can indicate a candidate interval in the second interval set via a bitmap. For example, the fourth indication information may be DCI.

[0052] In the embodiment of the present disclosure, the above four indications may be used individually or in combination, and the first interval set and the second interval set may be the same set or different sets.

[0053] In addition, the first indication information, the second indication information, the third indication information, and the fourth indication information may be sent by the network device to the terminal device via physical layer signaling. For example, the physical layer signaling may be scheduling signaling.

[0054] In an embodiment of the present application, a terminal device may receive physical layer signaling or higher layer signaling and determine one of the first to fourth indication information from the physical layer signaling or higher layer signaling. In some implementations, one of the first to fourth indication information may be carried in a designated information field of the physical layer signaling or higher layer signaling. Correspondingly, the terminal device may obtain one of the first to fourth indication information in the designated information field after receiving the physical layer signaling or higher layer signaling. In another implementation, one of the first to fourth indication information may be carried in a configurable information field of the physical layer signaling or higher layer signaling. Correspondingly, the terminal device may obtain one of the first to fourth indication information in the configurable information field after receiving the physical layer signaling or higher layer signaling. The configurable information field may be an idle information field or a reusable information field on the physical layer signaling or on the higher layer signaling.

[0055] In an embodiment of the present application, the interval set includes multiple candidate intervals. The number of bits in the information field that one of the first to fourth indicators must occupy to indicate a specific 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 indicate a specific interval. If the interval set includes four candidate intervals, two bits must be occupied to indicate a specific interval.

[0056] Alternatively, the terminal device may stop detecting a scheduling command for the same HARQ process from a first time domain unit at which reception of a transmission block (TB) transmitted on a physical downlink shared channel (PDSCH) is completed, and may re-detect the scheduling command for the HARQ process when a second time domain unit is reached. That is, the terminal device may determine the time domain unit between the second time domain unit and the first time domain unit as an interval.

[0057] The terminal device is configured with one HARQ process called HP1. As shown in Figure 3, the interval determined by the terminal device during which no detection of scheduling signaling for scheduling HP1 transmission is performed is X. The terminal device transmits TB1 using HP1. After the transmission of TB1 ends, the time domain falls into interval X. During interval X, the terminal device does not perform detection of scheduling signaling for HP1.

[0058] In an embodiment of the present application, a scheduling signaling interval is determined, and the terminal device does not perform detection of scheduling signaling that schedules transmission of the same HARQ process within the interval. In the present 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, which reduces the detection complexity of the terminal device and does not reduce the detection capability of the terminal device by reducing the detection frequency, thereby achieving both the detection complexity and the 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 indication information is reported to a network device, the capability indication information is used to indicate the data demodulation capability of the terminal device, and the data demodulation capability is used by the network device to determine an interval.

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

[0062] Alternatively, the terminal device may actively report the capability indication information to the network device. In some implementations, the terminal device may report the capability indication information to the network device during the initial access process. In other implementations, the terminal device may report the capability indication information to the network device after initial access is completed.

[0063] Optionally, the terminal device can receive request information sent by the network device, and the request information is used to request the terminal device to report capability indication information to the network device. Upon receiving the request information, the terminal device can report the capability indication information to the network device.

[0064] In the embodiments of the present application, after receiving the capability indication 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 the data demodulation capability, thereby eliminating the need for the terminal device to detect frequently, reducing the complexity of detection, and avoiding reducing the detection frequency and reducing the detection capability of the terminal device.

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

[0066] Optionally, after the network device determines the intervals, the terminal device can receive the intervals transmitted by the network device. In some implementations, the terminal device can receive signaling from the network device, where the intervals are included in the signaling. In other implementations, the terminal device can receive a set of intervals configured via one signaling, and further receive an interval within the set of intervals indicated by another signaling. The intervals are adaptive intervals determined for the terminal device by the network device based on its data demodulation capabilities.

[0067] Regarding the specific process in which the network device instructs the terminal device about the interval, reference can be made to the relevant content described in the above embodiment, and therefore, a repeated description will be omitted here.

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

[0069] In an embodiment of the present application, a scheduling signaling interval is determined, and the terminal device does not perform detection of scheduling signaling that schedules transmission of the same HARQ process within the interval. In the present 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, which reduces the detection complexity of the terminal device and does not reduce the detection capability of the terminal device by reducing the detection frequency, thereby achieving both the detection complexity and the 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 interval of the scheduling signaling is determined. In S502, detection of scheduling signaling that schedules transmission of the same HARQ process within the interval is not performed.

[0072] For a specific explanation of steps S501 and S502, the relevant contents in each embodiment of the present application can be referred to, and therefore a repeated explanation will be omitted here.

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

[0074] In some implementations, two or more HARQ processes may be configured in a terminal device. When multiple HARQ processes are configured in a terminal device, the terminal device performs detection of transmission scheduling signaling for the HARQ processes in time sequence. Within an interval, the terminal device does not re-perform detection of transmission scheduling signaling for the same HARQ process, but may perform detection of transmission scheduling signaling for another HARQ process.

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

[0076] In an embodiment of the present application, a scheduling signaling interval is determined, and the terminal device does not perform detection of scheduling signaling that schedules transmission of the same HARQ process within the interval, and can perform detection of scheduling signaling for another HARQ process within the interval. In the present 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 detection complexity of the terminal device and not reducing the detection frequency to reduce the detection capability of the terminal device, thereby achieving both the detection complexity and detection capability of the terminal device. Furthermore, detection of scheduling signaling for another HARQ process can be performed within the interval, allowing transmission of the other HARQ process to be performed normally, thereby 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 interval of the scheduling signaling is determined. In S702, an interval is instructed to the terminal device, and the terminal device is instructed not to perform detection of scheduling signaling that schedules transmission of the same HARQ process within the interval.

[0079] In an embodiment of the present application, in order to reduce the complexity of detection of a terminal device and save energy consumption, a network device can determine an interval of one scheduling signaling for a terminal device and indicate the interval to the terminal device, where the terminal device does not need to detect scheduling signaling of the same HARQ process within the interval.

[0080] Alternatively, the network device may determine the interval of the scheduling signaling for the terminal device based on a protocol agreement or the data demodulation capability of the terminal device.

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

[0082] Alternatively, the network device may determine the interval of the scheduling signaling based on the second indication information. In some implementations, the network device may send the second indication information to the terminal device, and the second indication information may include a scheduling signaling detection interval configured for the terminal device. The second indication information may be RRC signaling, MAC-CE signaling, or other higher layer signaling, but is not limited thereto in the present application.

[0083] Alternatively, the network device may instruct the terminal device of an interval for scheduling signaling based on the third indication information and the fourth indication information. In some implementations, the network device may send third indication information to the terminal device, and the third indication information includes a second interval set configured for the terminal device by the network device. The second interval set may include one or more candidate intervals. The third indication information may be, but is not limited to, RRC signaling, MAC-CE signaling, or other higher layer signaling.

[0084] Furthermore, the network device may transmit fourth indication information to the terminal device, and the terminal device may determine an interval from the second interval set based on the fourth indication information. Optionally, the fourth indication information may include an index value of a candidate interval in the second interval set, and the terminal device may determine the candidate interval indicated by the index value as the interval for detecting the scheduling signaling. Optionally, the fourth indication information may indicate the candidate interval in the second interval set via a bitmap. For example, the fourth indication information may be a DCI.

[0085] In addition, the first indication information, the second indication information, the third indication information, and the fourth indication information may be sent by the network device to the terminal device via physical layer signaling, for example, the physical layer signaling may be scheduling signaling.

[0086] In an embodiment of the present application, a network device may transmit physical layer signaling or higher layer signaling to a terminal device, where the physical layer signaling or higher layer signaling includes one of first to fourth indication information. In some implementations, the network device may carry one of the first to fourth indication information in a designated information field of the physical layer signaling or higher layer signaling. Correspondingly, the terminal device may obtain one of the first to fourth indication information in the designated information field after receiving the physical layer signaling or higher layer signaling. In another implementation, the network device may carry one of the first to fourth indication information in a configurable information field of the physical layer signaling or higher layer signaling. Correspondingly, the terminal device may obtain one of the first to fourth indication information in the configurable information field after receiving the physical layer signaling or higher layer signaling. The configurable information field may be an idle information field or a reusable information field in the scheduling signaling.

[0087] In an embodiment of the present application, the interval set includes multiple candidate intervals. The number of bits in the information field that one of the first to fourth indicators must occupy to indicate a specific 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 indicate a specific interval. If the interval set includes four candidate intervals, two bits must be occupied to indicate a specific interval.

[0088] Alternatively, the network device may instruct the terminal device to stop detecting a scheduling command for the same HARQ process from a first time domain unit in which the terminal device has finished receiving the TB transmitted on the PDSCH, and when the terminal device reaches a second time domain unit in which it starts detecting the scheduling command for the HARQ process again, the terminal device may redetect the scheduling command for the HARQ process, i.e., the terminal device may determine the time domain unit between the second time domain unit and the first time domain unit as an interval.

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

[0090] In an embodiment of the present application, a scheduling signaling interval is determined and instructed to a terminal device, so that the terminal device does not perform detection of scheduling signaling that schedules transmission of the same HARQ process within the interval. In the present application, by setting a scheduling signaling interval for a terminal device, the terminal device does not need to frequently perform detection of scheduling signaling for the same HARQ process, which reduces the detection complexity of the terminal device and does not reduce the detection frequency and thereby reduce the detection capability of the terminal device, thereby achieving both the detection 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. 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 S801 to S803.

[0092] In S801, capability indication information reported by a terminal device is received, and the capability indication information is used to indicate the data demodulation capability of the terminal device. In S802, the interval is determined based on the data demodulation capability.

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

[0094] Alternatively, the network device may receive capability indication information actively reported by the terminal device. In some implementations, the network device may receive capability indication information reported by the terminal device during the initial access process. In other implementations, the network device may receive capability indication information reported by the terminal device after the initial access is completed.

[0095] Alternatively, the network device may transmit request information to the terminal device, the request information being used to request the terminal device to report capability indication information to the network device. Furthermore, upon receiving the request information, the terminal device may report the capability indication information to the network device. Correspondingly, the network device may receive the capability indication information reported by the terminal device based on the request information.

[0096] In the embodiment of the present application, after the network device receives the capability indication information, it can determine the data demodulation capability of the terminal device, and further determine an appropriate interval for the terminal device based on the data demodulation capability, so that the terminal device does not need to perform detection frequently, which can reduce the detection complexity and avoid reducing the detection frequency and reducing the detection capability of the terminal device.

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

[0098] For a specific explanation of step S803, please refer to the relevant descriptions in each embodiment of the present application, and therefore a repeated explanation will be omitted here.

[0099] In an embodiment of the present application, a scheduling signaling interval is determined and instructed to a terminal device, so that the terminal device does not perform detection of scheduling signaling that schedules transmission of the same HARQ process within the interval. In the present application, by setting a scheduling signaling interval for a terminal device, the terminal device does not need to frequently perform detection of scheduling signaling for the same HARQ process, which reduces the detection complexity of the terminal device and does not reduce the detection frequency and thereby reduce the detection capability of the terminal device, thereby achieving both the detection complexity and detection capability of the terminal device.
