[0035] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0036] First, a brief introduction to some of the terms used in this disclosure:

[0037] PDCCH Listen Adaptive:

[0038] The R17 power saving project proposed a PDCCH monitoring adaptation scheme, which uses a bit field containing N bits in the scheduling DCI to indicate the PDCCH monitoring adaptation behavior.

[0039] When the terminal device receives the PDCCH listening adaptive indication (i.e., the aforementioned DCI), the terminal device's behavior can be one of the following:

[0040] Behavior 1: Do not activate PDCCH skipping

[0041] Action 1A: Stop PDCCH listening for duration X (i.e., PDCCH skipping). The network device can dynamically indicate the value of X in the DCI.

[0042] Action 2: Stop listening to the search space in SSSG#1 and SSSG#2 (if this configuration exists), and listen to the search space in SSSG#0.

[0043] Action 2A: Stop listening to the search space in SSSG#0 and SSSG#2 (if this configuration exists), and listen to the search space in SSSG#1.

[0044] Action 2B: Stop listening to the search space in SSSG#0 and SSSG#1, and listen to the search space in SSSG#2 (if this configuration exists).

[0045] Cancel the suspended SR:

[0046] In related technologies, the following two reasons are defined for canceling a suspended SR:

[0047] (1) If the terminal device sends a Medium Access Control (MAC) Protocol Data Unit (PDU) containing a Buffer State Report (BSR), the pending SR before the MAC PDU is assembled can be canceled.

[0048] (2) If the terminal device receives the uplink scheduling instruction and can meet the transmission requirements of all suspended uplink data, the suspended SR can be cancelled.

[0049] If the SR is still in a suspended state after the terminal device sends it, how should the terminal device handle the SR process after receiving the PDCCH listening and adaptive indication sent by the network device? There is no solution provided in the relevant technology.

[0050] The solutions provided by the embodiments of this disclosure will now be described.

[0051] Figure 1 A block diagram of a communication system provided in an exemplary embodiment of the present disclosure is shown. The communication system may include an access network 12 and a terminal device 14.

[0052] Access network 12 includes a plurality of access network devices 120. Each access network device 120 may be a base station, which is a device deployed in the access network to provide wireless communication functionality to a terminal device (hereinafter referred to as "terminal") 14. Base stations may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the names of devices with base station functionality may differ; for example, in Long Term Evolution (LTE) systems, they are called eNodeB or eNB; in 5G New Radio (NR) systems, they are called gNodeB or gNB. As communication technologies evolve, the description of "base station" may change. For the convenience of the description in the embodiments of this disclosure, the devices that provide wireless communication functionality to the terminal device 14 are collectively referred to as network devices.

[0053] Terminal device 14 may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment, mobile stations (MS), terminal devices, etc. For ease of description, the devices mentioned above are collectively referred to as terminal devices. Access network device 120 and terminal device 14 communicate with each other through some air interface technology, such as a Uu interface.

[0054] The technical solutions of this disclosure can be applied to various communication systems, such as: Global System of Mobile Communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Advanced Long Term Evolution (LTE-A) system, New Radio (NR) system, evolution of NR system, LTE-based access to Unlicensed spectrum (LTE-U) system, NR-U system, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, and Wireless Local Area Network (WLAN). Networks (WLAN), Wireless Fidelity (WiFi), next-generation communication systems, or other communication systems.

[0055] Traditional communication systems typically support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communication but also, for example, device-to-device (D2D) communication, machine-to-machine (M2M) communication, machine-type communication (MTC), vehicle-to-vehicle (V2V) communication, and vehicle-to-everything (V2X) systems. The embodiments disclosed herein can also be applied to these communication systems.

[0056] Figure 2 This disclosure illustrates a method flowchart for processing a scheduling request procedure according to an exemplary embodiment of the present disclosure. The method is applied to... Figure 1 In the terminal device of the communication system shown, the method includes:

[0057] Step 210: The terminal device receives the PDCCH listening adaptive indication sent by the network device.

[0058] Network devices can send PDCCH listen-adaptive indications to terminal devices. Correspondingly, the terminal devices receive the PDCCH listen-adaptive indications sent by the network devices.

[0059] Among them, the PDCCH snooping adaptation indication is a message sent by the network device to the terminal device to indicate that PDCCH snooping adjustments should be made.

[0060] Step 220: If the terminal device has an SR pending and the received PDCCH listening adaptive indication carries the first indication information, the terminal device cancels the pending SR.

[0061] In this embodiment of the disclosure, the terminal device is executing a scheduling request process, which is a process of requesting uplink resources by sending an SR. The current progress is as follows: the terminal device has sent an SR to the network device, the SR is in a pending state, and there is pending data to be transmitted on the terminal device side.

[0062] The suspended state is a state that occurs when an SR is triggered but has not yet been canceled.

[0063] When an SR is suspended, the terminal device receives a PDCCH snooping adaptation indication sent by the network device; if the received PDCCH snooping adaptation indication carries first indication information, the terminal device cancels the suspended SR. That is, if an SR is suspended and a PDCCH snooping adaptation indication containing the first indication information is received, the terminal device cancels the suspended SR.

[0064] Understandably, during the scheduling request process of a terminal device, when requesting uplink resources by sending a Scheduler (SR), after the terminal device sends the SR and it is in a suspended state, it needs to listen to the PDCCH to confirm whether the network device has responded to the SR. Since the terminal device subsequently receives a PDCCH listener adaptation indication, which is used to instruct PDCCH listener adjustments, this received PDCCH listener adaptation indication will affect the terminal device's behavior in confirming whether the network device has responded to the SR.

[0065] The first indication information is the information carried in the PDCCH listening adaptive indication.

[0066] In this embodiment of the disclosure, the first indication information is information that causes the terminal device to believe that the scheduling request (SR) is difficult to satisfy. Therefore, the terminal device cancels the suspended SR and terminates the current scheduling request process. The aforementioned "SR difficult to satisfy" can also be understood as: there is no need to continue suspending the SR, the scheduling request process has failed, etc.

[0067] In summary, the scheduling request process processing method provided in this embodiment, when there is an SR suspension, the terminal device receives a PDCCH listening adaptive indication sent by the network device. When the received PDCCH listening adaptive indication carries first indication information, the terminal device believes that the SR is difficult to satisfy because the first indication information makes the terminal device think that the SR is difficult to satisfy. Therefore, the terminal device cancels the suspended SR, avoiding unnecessary continuous suspension of the SR by the terminal device and wasting the storage and computing resources of the terminal device.

[0068] In one possible implementation, the first instruction information includes: information indicating that the PDCCH should be skipped.

[0069] Figure 3 This disclosure illustrates a method flowchart for processing a scheduling request procedure according to an exemplary embodiment of the present disclosure. The method is applied to... Figure 1 In the terminal device of the communication system shown, the method includes:

[0070] Step 310: The terminal device receives the PDCCH listening adaptive indication sent by the network device.

[0071] In some implementations, the network device sends a PDCCH snooping adaptation indication to the terminal device, and the terminal device receives the PDCCH snooping adaptation indication sent by the network device.

[0072] Among them, the PDCCH snooping adaptation indication is a message sent by the network device to the terminal device to indicate that PDCCH snooping adjustments should be made.

[0073] Optionally, the PDCCH listener adaptive indication is carried in the scheduling DCI. For example, the scheduling DCI includes a bit field containing N bits, which is used to indicate the PDCCH listener adaptive indication.

[0074] • The scheduling DCI is the DCI used for downlink scheduling.

[0075] That is, the PDCCH listening adaptive indication is carried in the DCI used for downlink scheduling.

[0076] • The scheduling DCI is the DCI used for uplink scheduling.

[0077] That is, the PDCCH listening adaptive indication is carried in the DCI used for uplink scheduling.

[0078] For example, the uplink scheduling here cannot meet the transmission requirements of all pending data to be transmitted corresponding to the SR.

[0079] The transmission requirements may include requirements related to the following aspects:

[0080] (1) The number of resources allocated by the uplink scheduling is insufficient to transmit all the pending data to be transmitted.

[0081] (2) The characteristics of the resources allocated by the uplink scheduling cannot meet the Quality of Service (QoS) requirements of all pending data to be transmitted.

[0082] For example, some logical channels require that the time domain length of the Physical Uplink Shared Channel (PUSCH) mapped to the mapped physical layer resource be a maximum of 4 time domain symbols. If the time domain length of the PUSCH allocated by the uplink scheduling is 8 symbols, then the resources allocated by the uplink scheduling cannot meet the transmission requirements of the pending data on that logical channel.

[0083] Step 320: When an SR is suspended and the received PDCCH listening adaptive indication carries first indication information, the terminal device cancels the suspended SR.

[0084] Among them, the information indicating that PDCCH should be skipped (i.e., PDCCH skipping indication) refers to the information that instructs the terminal device not to perform PDCCH listening for a period of time.

[0085] Understandably, during the scheduling request process of a terminal device, when requesting uplink resources by sending an SR (Schedule Request), after sending the SR and placing it in a suspended state, the terminal device needs to listen to the PDCCH (Programmable Channel Communication) to confirm whether the network device has responded to the SR. Since the terminal device subsequently receives a PDCCH listening adaptive indication, and this indication carries first indication information, including an instruction to skip the PDCCH, the terminal device will, based on this first indication information, not perform PDCCH listening for a period of time. If the SR remains suspended during this period, the terminal device cannot confirm whether the network device has responded to the SR. Therefore, the terminal device cancels the suspended SR.

[0086] Optionally, the information indicating the skipping of the PDCCH carries a skip duration, and the skip duration exceeds a first duration; wherein, the skip duration is the duration during which the PDCCH is not monitored. Optionally, the PDCCH includes a Type 3 common search space and a UE-specific search space.

[0087] That is, the skipping duration indicated by the information indicating that the PDCCH is skipped is greater than or equal to (or greater than) the first duration.

[0088] For example, the first duration is a time threshold calculated by the terminal device based on the configuration on the network device side. The above configuration can be a configuration related to SR.

[0089] If the skip duration is less than the first duration, meaning the terminal device skips the PDCCH listening time for a short period, the terminal device can continue listening to the DCI used for uplink scheduling after the skip duration. During this shorter skip duration, there is no need to cancel the SR.

[0090] If the skip duration is longer than the first duration, meaning the terminal device skips listening to the PDCCH for a longer period, the terminal device will not be able to obtain the DCI for uplink scheduling during this skip duration. In other words, the scheduling request cannot be satisfied during this longer period, so the SR can be canceled.

[0091] The following is a further explanation of the first duration.

[0092] • The first duration is determined based on the scheduling request-prohibit timer (sr-ProhibitTimer) configured on the network device.

[0093] For example, the first duration = sr - ProhibitTimer.

[0094] The `sr-ProhibitTimer` is a timer on the terminal device side, and its duration is configured by the network device. The network device can configure one `sr-ProhibitTimer` for each SR configuration. For each SR configuration, after sending an SR, the terminal device is prohibited from sending another SR within the `sr-ProhibitTimer` duration.

[0095] Optionally, if the network device is configured with multiple sr-ProhibitTimers, the first duration is determined based on the maximum value among the multiple sr-ProhibitTimers.

[0096] For example, the first duration = sr - the maximum value of ProhibitTimer.

[0097] • The first duration is determined based on the sr-ProhibitTimer and scheduling request-transmission maximum (sr-TransMax) configured on the network device.

[0098] For example, the first duration = sr - ProhibitTimer * sr - TransMax.

[0099] Here, sr-TransMax is the maximum number of times a terminal device can repeatedly initiate a Signal Request (SR). A network device can configure one sr-TransMax for each SR configuration. If the terminal device does not receive a response from the network device after exceeding this number of repeated transmissions, it is considered that a beam failure or link failure has occurred.

[0100] Optionally, if the network device is configured with multiple sr-ProhibitTimers and multiple sr-TransMax, the first duration is determined based on the maximum value among the multiple sr-ProhibitTimers and the maximum value among the multiple sr-TransMax.

[0101] For example, the first duration = sr - maximum value of ProhibitTimer * sr - maximum value of TransMax.

[0102] In summary, the scheduling request process processing method provided in this embodiment, when an SR is suspended, the terminal device receives a PDCCH listening adaptive indication sent by the network device. When the received PDCCH listening adaptive indication carries first indication information, since the first indication information includes information indicating to skip the PDCCH, the terminal device considers that the SR is difficult to satisfy. Therefore, the terminal device cancels the suspended SR, avoiding unnecessary continuous suspension of the SR by the terminal device and wasting the storage and computing resources of the terminal device.

[0103] In another possible implementation, the first instruction information includes: information indicating a switch to an empty search space set group (SSSG).

[0104] Figure 4 This disclosure illustrates a method flowchart for processing a scheduling request procedure according to an exemplary embodiment of the present disclosure. The method is applied to... Figure 1 In the terminal device of the communication system shown, the method includes:

[0105] Step 410: The terminal device receives the PDCCH listening adaptive indication sent by the network device.

[0106] In some implementations, the network device may send a PDCCH snooping adaptation indication to the terminal device. Correspondingly, the terminal device receives the PDCCH snooping adaptation indication sent by the network device.

[0107] Among them, the PDCCH snooping adaptation indication is a message sent by the network device to the terminal device to indicate that PDCCH snooping adjustments should be made.

[0108] Optionally, the PDCCH listener adaptive indication is carried in the scheduling DCI. For example, the scheduling DCI includes a bit field containing N bits, which is used to indicate the PDCCH listener adaptive indication.

[0109] • The scheduling DCI is the DCI used for downlink scheduling.

[0110] That is, the PDCCH listening adaptive indication is carried in the DCI used for downlink scheduling.

[0111] • The scheduling DCI is the DCI used for uplink scheduling.

[0112] That is, the PDCCH listening adaptive indication is carried in the DCI used for uplink scheduling.

[0113] For example, the uplink scheduling here cannot meet the transmission requirements of all pending data to be transmitted corresponding to the SR.

[0114] The transmission requirements may include requirements related to the following aspects:

[0115] (1) The number of resources allocated by the uplink scheduling is insufficient to transmit all the pending data to be transmitted.

[0116] (2) The characteristics of the resources allocated by the uplink scheduling cannot meet the QoS requirements of all pending data to be transmitted.

[0117] For example, on certain logical channels, the pending data to be transmitted requires a maximum time-domain length of 4 time-domain symbols for the mapped physical layer resource PUSCH. If the time-domain length of the PUSCH allocated by the uplink scheduling is 8 symbols, then the resources allocated by the uplink scheduling cannot meet the transmission requirements of the pending data on that logical channel.

[0118] Step 420: If the terminal device has an SR pending and the received PDCCH listening adaptive indication carries first indication information, the first indication information includes: information indicating switching to an empty SSSG, then the terminal device cancels the pending SR.

[0119] The information indicating a switch to an empty SSSG refers to instructing the terminal device to switch to an SSSG, listen to the search space in that SSSG, and that the SSSG does not contain any search space; it is an empty SSSG.

[0120] Understandably, during the scheduling request process of a terminal device, when requesting uplink resources by sending an SR (Schedule Request), after sending the SR and placing it in a suspended state, the terminal device needs to perform PDCCH (Programmable Channel Communication) listening. This involves checking the search space to see if the network device has sent a PDCCH to the terminal device, thus confirming whether the network device has responded to the SR. Since the terminal device subsequently receives a PDCCH listening adaptive indication, and this indication carries first indication information, including an indication to switch to an empty SSSG (Search Space Grid), the terminal device will switch to an empty SSSG (Search Space Grid) without any search space based on this first indication information. If the SR remains suspended at this point, the terminal device cannot confirm whether the network device has responded to the SR. Therefore, the terminal device cancels the suspended SR.

[0121] Optionally, the information indicating the switch to an empty SSSG carries a timing value, and the timing value exceeds a first duration; wherein the timing value is the duration of the switch to an empty SSSG.

[0122] That is, the timing value of the information indicating the switch to an empty SSSG is greater than or equal to (or greater than) the first duration.

[0123] For example, the first duration is a time threshold calculated by the terminal device based on the configuration on the network device side. The above configuration can be a configuration related to SR.

[0124] If the timeout value is less than the first duration, meaning the time during which the terminal device switches to an empty SSSG and cannot listen to the PDCCH is short, the terminal device can continue to listen to the DCI used for uplink scheduling after the timeout value. Within this short timeout value, there is no need to cancel the SR.

[0125] If the timer value is greater than the first duration, meaning the terminal device switches to an empty SSSG and cannot listen to the PDCCH for a long time, the terminal device will not be able to obtain the DCI for uplink scheduling within this timer value. In other words, the scheduling request cannot be satisfied within this long period of time, so the SR can be canceled.

[0126] The following is a further explanation of the first duration.

[0127] • The first duration is determined based on the sr-ProhibitTimer configured on the network device.

[0128] For example, the first duration = sr - ProhibitTimer.

[0129] The `sr-ProhibitTimer` is a timer on the terminal device side, and its duration is configured by the network device. The network device can configure one `sr-ProhibitTimer` for each SR configuration. For each SR configuration, after sending an SR, the terminal device is prohibited from sending another SR within the `sr-ProhibitTimer` duration.

[0130] Optionally, if the network device is configured with multiple sr-ProhibitTimers, the first duration is determined based on the maximum value among the multiple sr-ProhibitTimers.

[0131] For example, the first duration = sr - the maximum value of ProhibitTimer.

[0132] • The first duration is determined based on the sr-ProhibitTimer and sr-TransMax configured on the network device.

[0133] For example, the first duration = sr - ProhibitTimer * sr - TransMax.

[0134] Here, sr-TransMax is the maximum number of times a terminal device can repeatedly initiate a Signal Request (SR). A network device can configure one sr-TransMax for each SR configuration. If the terminal device does not receive a response from the network device after exceeding this number of repeated transmissions, it is considered that a beam failure or link failure has occurred.

[0135] Optionally, if the network device is configured with multiple sr-ProhibitTimers and multiple sr-TransMax, the first duration is determined based on the maximum value among the multiple sr-ProhibitTimers and the maximum value among the multiple sr-TransMax.

[0136] For example, the first duration = sr - maximum value of ProhibitTimer * sr - maximum value of TransMax.

[0137] In summary, the scheduling request process processing method provided in this embodiment, when an SR is suspended, the terminal device receives a PDCCH listening adaptive indication sent by the network device. When the received PDCCH listening adaptive indication carries first indication information, since the first indication information includes information indicating a switch to an empty SSSG, the terminal device considers that the SR is difficult to satisfy. Therefore, the terminal device cancels the suspended SR, avoiding unnecessary continuous suspension of the SR by the terminal device and wasting the terminal device's storage and computing resources.

[0138] Figure 5 This disclosure illustrates a method flowchart for processing a scheduling request procedure according to an exemplary embodiment of the present disclosure. The method is applied to... Figure 1 In the network device of the communication system shown, the method includes:

[0139] Step 510: The network device sends a PDCCH snooping adaptation indication to the terminal device, so that the terminal device cancels the suspended SR if there is an SR pending and the received PDCCH snooping adaptation indication carries the first indication information.

[0140] Network devices can send PDCCH listen-adaptive indications to terminal devices. Correspondingly, the terminal devices receive the PDCCH listen-adaptive indications sent by the network devices.

[0141] Among them, the PDCCH snooping adaptation indication is a message sent by the network device to the terminal device to indicate that PDCCH snooping adjustments should be made.

[0142] In this embodiment of the disclosure, before the terminal device receives the PDCCH listening adaptive indication, the terminal device is executing a scheduling request process. This scheduling request process is a process of requesting to obtain uplink resources by sending an SR. The current progress is as follows: the terminal device has sent an SR to the network device, and the SR is in a pending state. There is pending data to be transmitted on the terminal device side.

[0143] The suspended state is a state that occurs when an SR is triggered but has not yet been canceled.

[0144] When an SR is suspended, the terminal device receives a PDCCH snooping adaptation indication sent by the network device; if the received PDCCH snooping adaptation indication carries first indication information, the terminal device cancels the suspended SR. That is, if an SR is suspended and a PDCCH snooping adaptation indication containing the first indication information is received, the terminal device cancels the suspended SR.

[0145] Understandably, during the scheduling request process of a terminal device, when requesting uplink resources by sending a Scheduler (SR), after the terminal device sends the SR and it is in a suspended state, it needs to listen to the PDCCH to confirm whether the network device has responded to the SR. Since the terminal device subsequently receives a PDCCH listener adaptation indication, which is used to instruct PDCCH listener adjustments, this received PDCCH listener adaptation indication will affect the terminal device's behavior in confirming whether the network device has responded to the SR.

[0146] The first indication information is the information carried in the PDCCH listening adaptive indication.

[0147] In this embodiment of the disclosure, the first indication information is information that causes the terminal device to believe that the scheduling request (SR) is difficult to satisfy. Therefore, the terminal device cancels the suspended SR and terminates the current scheduling request process. The aforementioned "SR difficult to satisfy" can also be understood as: there is no need to continue suspending the SR, the scheduling request process has failed, etc.

[0148] In summary, the scheduling request process processing method provided in this embodiment, when there is an SR suspension, the terminal device receives a PDCCH listening adaptive indication sent by the network device. When the received PDCCH listening adaptive indication carries first indication information, the terminal device believes that the SR is difficult to satisfy because the first indication information makes the terminal device think that the SR is difficult to satisfy. Therefore, the terminal device cancels the suspended SR, avoiding unnecessary continuous suspension of the SR by the terminal device and wasting the storage and computing resources of the terminal device.

[0149] In one possible implementation, the first instruction information includes: information indicating that the PDCCH should be skipped.

[0151] Step 610: The network device sends a PDCCH listening adaptation indication to the terminal device, so that the terminal device cancels the suspended SR when there is an SR suspension and the received PDCCH listening adaptation indication carries first indication information, the first indication information including: information indicating to skip PDCCH.

[0152] In some implementations, the network device sends a PDCCH snooping adaptation indication to the terminal device, and the terminal device receives the PDCCH snooping adaptation indication sent by the network device.

[0153] Among them, the PDCCH snooping adaptation indication is a message sent by the network device to the terminal device to indicate that PDCCH snooping adjustments should be made.

[0154] Optionally, the PDCCH listener adaptive indication is carried in the scheduling DCI. For example, the scheduling DCI includes a bit field containing N bits, which is used to indicate the PDCCH listener adaptive indication.

[0155] • The scheduling DCI is the DCI used for downlink scheduling.

[0156] That is, the PDCCH listening adaptive indication is carried in the DCI used for downlink scheduling.

[0157] • The scheduling DCI is the DCI used for uplink scheduling.

[0158] That is, the PDCCH listening adaptive indication is carried in the DCI used for uplink scheduling.

[0159] For example, the uplink scheduling here cannot meet the transmission requirements of all pending data to be transmitted corresponding to the SR.

[0160] The transmission requirements may include requirements related to the following aspects:

[0161] (1) The number of resources allocated by the uplink scheduling is insufficient to transmit all the pending data to be transmitted.

[0162] (2) The characteristics of the resources allocated by the uplink scheduling cannot meet the Quality of Service (QoS) requirements of all pending data to be transmitted.

[0163] For example, some logical channels require that the time domain length of the Physical Uplink Shared Channel (PUSCH) mapped to the mapped physical layer resource be a maximum of 4 time domain symbols. If the time domain length of the PUSCH allocated by the uplink scheduling is 8 symbols, then the resources allocated by the uplink scheduling cannot meet the transmission requirements of the pending data on that logical channel.

[0164] Among them, the information indicating that PDCCH should be skipped (i.e., PDCCH skipping indication) refers to the information that instructs the terminal device not to perform PDCCH listening for a period of time.

[0165] Understandably, during the scheduling request process of a terminal device, when requesting uplink resources by sending an SR (Schedule Request), after sending the SR and placing it in a suspended state, the terminal device needs to listen to the PDCCH (Programmable Channel Communication) to confirm whether the network device has responded to the SR. Since the terminal device subsequently receives a PDCCH listening adaptive indication, and this indication carries first indication information, including an instruction to skip the PDCCH, the terminal device will, based on this first indication information, not perform PDCCH listening for a period of time. If the SR remains suspended during this period, the terminal device cannot confirm whether the network device has responded to the SR. Therefore, the terminal device cancels the suspended SR.

[0166] Optionally, the information indicating the skipping of the PDCCH carries a skip duration, and the skip duration exceeds a first duration; wherein, the skip duration is the duration during which the PDCCH is not monitored. Optionally, the PDCCH includes a Type 3 common search space and a UE-specific search space.

[0167] That is, the skipping duration indicated by the information indicating that the PDCCH is skipped is greater than or equal to (or greater than) the first duration.

[0168] For example, the first duration is a time threshold calculated by the terminal device based on the configuration on the network device side. The above configuration can be a configuration related to SR.

[0169] If the skip duration is less than the first duration, meaning the terminal device skips the PDCCH listening time for a short period, the terminal device can continue listening to the DCI used for uplink scheduling after the skip duration. During this shorter skip duration, there is no need to cancel the SR.

[0170] If the skip duration is longer than the first duration, meaning the terminal device skips listening to the PDCCH for a longer period, the terminal device will not be able to obtain the DCI for uplink scheduling during this skip duration. In other words, the scheduling request cannot be satisfied during this longer period, so the SR can be canceled.

[0171] The following is a further explanation of the first duration.

[0172] • The first duration is determined based on the scheduling request-prohibit timer (sr-ProhibitTimer) configured on the network device.

[0173] For example, the first duration = sr - ProhibitTimer.

[0174] The `sr-ProhibitTimer` is a timer on the terminal device side, and its duration is configured by the network device. The network device can configure one `sr-ProhibitTimer` for each SR configuration. For each SR configuration, after sending an SR, the terminal device is prohibited from sending another SR within the `sr-ProhibitTimer` duration.

[0175] Optionally, if the network device is configured with multiple sr-ProhibitTimers, the first duration is determined based on the maximum value among the multiple sr-ProhibitTimers.

[0176] For example, the first duration = sr - the maximum value of ProhibitTimer.

[0177] • The first duration is determined based on the sr-ProhibitTimer and scheduling request-transmission maximum (sr-TransMax) configured on the network device.

[0178] For example, the first duration = sr - ProhibitTimer * sr - TransMax.

[0179] Here, sr-TransMax is the maximum number of times a terminal device can repeatedly initiate a Signal Request (SR). A network device can configure one sr-TransMax for each SR configuration. If the terminal device does not receive a response from the network device after exceeding this number of repeated transmissions, it is considered that a beam failure or link failure has occurred.

[0180] Optionally, if the network device is configured with multiple sr-ProhibitTimers and multiple sr-TransMax, the first duration is determined based on the maximum value among the multiple sr-ProhibitTimers and the maximum value among the multiple sr-TransMax.

[0181] For example, the first duration = sr - maximum value of ProhibitTimer * sr - maximum value of TransMax.

[0182] In summary, the scheduling request process processing method provided in this embodiment, when an SR is suspended, the terminal device receives a PDCCH listening adaptive indication sent by the network device. When the received PDCCH listening adaptive indication carries first indication information, since the first indication information includes information indicating to skip the PDCCH, the terminal device considers that the SR is difficult to satisfy. Therefore, the terminal device cancels the suspended SR, avoiding unnecessary continuous suspension of the SR by the terminal device and wasting the storage and computing resources of the terminal device.

[0183] In another possible implementation, the first instruction information includes: information indicating a switch to an empty SSSG.

[0184] Figure 7 This disclosure illustrates a method flowchart for processing a scheduling request procedure according to an exemplary embodiment of the present disclosure. The method is applied to... Figure 1 In the network device of the communication system shown, the method includes:

[0185] Step 710: The network device sends a PDCCH listening adaptation indication to the terminal device, so that the terminal device cancels the suspended SR when there is an SR suspension and the received PDCCH listening adaptation indication carries first indication information, the first indication information including: information indicating switching to an empty SSSG.

[0186] In some implementations, the network device may send a PDCCH snooping adaptation indication to the terminal device. Correspondingly, the terminal device receives the PDCCH snooping adaptation indication sent by the network device.

[0187] Among them, the PDCCH snooping adaptation indication is a message sent by the network device to the terminal device to indicate that PDCCH snooping adjustments should be made.

[0188] Optionally, the PDCCH listener adaptive indication is carried in the scheduling DCI. For example, the scheduling DCI includes a bit field containing N bits, which is used to indicate the PDCCH listener adaptive indication.

[0189] • The scheduling DCI is the DCI used for downlink scheduling.

[0190] That is, the PDCCH listening adaptive indication is carried in the DCI used for downlink scheduling.

[0191] • The scheduling DCI is the DCI used for uplink scheduling.

[0192] That is, the PDCCH listening adaptive indication is carried in the DCI used for uplink scheduling.

[0193] For example, the uplink scheduling here cannot meet the transmission requirements of all pending data to be transmitted corresponding to the SR.

[0194] The transmission requirements may include requirements related to the following aspects:

[0195] (1) The number of resources allocated by the uplink scheduling is insufficient to transmit all the pending data to be transmitted.

[0196] (2) The characteristics of the resources allocated by the uplink scheduling cannot meet the QoS requirements of all pending data to be transmitted.

[0197] For example, on certain logical channels, the pending data to be transmitted requires a maximum time-domain length of 4 time-domain symbols for the mapped physical layer resource PUSCH. If the time-domain length of the PUSCH allocated by the uplink scheduling is 8 symbols, then the resources allocated by the uplink scheduling cannot meet the transmission requirements of the pending data on that logical channel.

[0198] The information indicating a switch to an empty SSSG refers to instructing the terminal device to switch to an SSSG, listen to the search space in that SSSG, and that the SSSG does not contain any search space; it is an empty SSSG.

[0199] Understandably, during the scheduling request process of a terminal device, when requesting uplink resources by sending an SR (Schedule Request), after sending the SR and placing it in a suspended state, the terminal device needs to perform PDCCH (Programmable Channel Communication) listening. This involves checking the search space to see if the network device has sent a PDCCH to the terminal device, thus confirming whether the network device has responded to the SR. Since the terminal device subsequently receives a PDCCH listening adaptive indication, and this indication carries first indication information, including an indication to switch to an empty SSSG (Search Space Grid), the terminal device will switch to an empty SSSG (Search Space Grid) without any search space based on this first indication information. If the SR remains suspended at this point, the terminal device cannot confirm whether the network device has responded to the SR. Therefore, the terminal device cancels the suspended SR.

[0200] Optionally, the information indicating the switch to an empty SSSG carries a timing value, and the timing value exceeds a first duration; wherein the timing value is the duration of the switch to an empty SSSG.

[0201] That is, the timing value of the information indicating the switch to an empty SSSG is greater than or equal to (or greater than) the first duration.

[0202] For example, the first duration is a time threshold calculated by the terminal device based on the configuration on the network device side. The above configuration can be a configuration related to SR.

[0203] If the timeout value is less than the first duration, meaning the time during which the terminal device switches to an empty SSSG and cannot listen to the PDCCH is short, the terminal device can continue to listen to the DCI used for uplink scheduling after the timeout value. Within this short timeout value, there is no need to cancel the SR.

[0204] If the timer value is greater than the first duration, meaning the terminal device switches to an empty SSSG and cannot listen to the PDCCH for a long time, the terminal device will not be able to obtain the DCI for uplink scheduling within this timer value. In other words, the scheduling request cannot be satisfied within this long period of time, so the SR can be canceled.

[0205] The following is a further explanation of the first duration.

[0206] • The first duration is determined based on the sr-ProhibitTimer configured on the network device.

[0207] For example, the first duration = sr - ProhibitTimer.

[0208] The `sr-ProhibitTimer` is a timer on the terminal device side, and its duration is configured by the network device. The network device can configure one `sr-ProhibitTimer` for each SR configuration. For each SR configuration, after sending an SR, the terminal device is prohibited from sending another SR within the `sr-ProhibitTimer` duration.

[0209] Optionally, if the network device is configured with multiple sr-ProhibitTimers, the first duration is determined based on the maximum value among the multiple sr-ProhibitTimers.

[0210] For example, the first duration = sr - the maximum value of ProhibitTimer.

[0211] • The first duration is determined based on the sr-ProhibitTimer and sr-TransMax configured on the network device.

[0212] For example, the first duration = sr - ProhibitTimer * sr - TransMax.

[0213] Here, sr-TransMax is the maximum number of times a terminal device can repeatedly initiate a Signal Request (SR). A network device can configure one sr-TransMax for each SR configuration. If the terminal device does not receive a response from the network device after exceeding this number of repeated transmissions, it is considered that a beam failure or link failure has occurred.

[0214] Optionally, if the network device is configured with multiple sr-ProhibitTimers and multiple sr-TransMax, the first duration is determined based on the maximum value among the multiple sr-ProhibitTimers and the maximum value among the multiple sr-TransMax.

[0215] For example, the first duration = sr - maximum value of ProhibitTimer * sr - maximum value of TransMax.

[0216] In summary, the scheduling request process processing method provided in this embodiment, when an SR is suspended, the terminal device receives a PDCCH listening adaptive indication sent by the network device. When the received PDCCH listening adaptive indication carries first indication information, since the first indication information includes information indicating a switch to an empty SSSG, the terminal device considers that the SR is difficult to satisfy. Therefore, the terminal device cancels the suspended SR, avoiding unnecessary continuous suspension of the SR by the terminal device and wasting the terminal device's storage and computing resources.
