Terminal device scheduling method and apparatus

Abstract

[Solution] An embodiment of the present application discloses a terminal device scheduling method and apparatus thereof applicable to the field of communications technology. The method performed by the terminal device includes: determining a resource for transmitting a random access message based on the processing capability of a physical layer channel / signal of the terminal device; and sending the random access message to a network device using the resource. The random access message sent using the resource instructs the network device to determine a random access message processing delay of the terminal device based on the resource corresponding to the random access message, and the random access message processing delay schedules the transmission of a subsequent random access message of the terminal device. In this manner, the network device can allocate different resource scheduling processes for subsequent random access messages to terminal devices with different processing capabilities, so that the terminal device can successfully transmit a message through resources reasonably allocated by scheduling, and avoids re-scheduling of resources when message transmission fails, avoiding resource waste, and improving resource utilization rate.

[0002] In the related technology, when a serving cell (SC) allows access by a terminal device with relaxed processing capabilities, if a network device schedules all terminal devices (including the terminal device with relaxed processing capabilities) that access the serving cell based on processing capabilities that are still not relaxed, the terminal device with relaxed processing capabilities does not have enough time to process or prepare a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH), and therefore it becomes difficult for the terminal device with relaxed processing capabilities to successfully transmit a random access message.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0065] To facilitate understanding, we first explain the terminology relevant to this application. 1. Physical uplink shared channel (PUSCH) The PUSCH is used to carry uplink higher layer / physical layer control signaling and user data. 2. Physical downlink shared channel (PDSCH) The PDSCH is used to carry downlink higher layer control signaling and user data. 3. Physical downlink control channel (PDCCH) The PDCCH channel transmits downlink control information (DCI) related to a physical uplink / downlink shared channel (PUSCH, PDSCH), and the DCI information includes related contents such as resource block (RB) allocation information, HARQ process identifier, etc. If a terminal device does not accurately decode the DCI information, it cannot accurately process PDSCH data or PUSCH data. 4. Bandwidth part (BWP) A bandwidth part (BWP) is a subset bandwidth of the terminal channel bandwidth, which flexibly adjusts the size of the bandwidth of transmission and reception by the terminal device through bandwidth adaptation in NR, so that the transmission and reception bandwidth of the terminal device may not be the same as the cell bandwidth. A terminal can only activate one uplink (UL) BWP and one downlink (DL) BWP at the same time, and one subcarrier spacing (SCS) is set for each BWP, and all signals and channels in the BWP use the SCS unless otherwise specified. 5. Hybrid automatic repeat request (HARQ) HARQ is a new communication technology based on FEC (Forward Error Correction) and ARQ (Automatic Repeat Request), which has been developed to achieve better interference prevention and fading resistance, and to improve system throughput (effectiveness) and data transmission reliability.

[0066] In order to better understand the terminal device scheduling method and apparatus disclosed in the embodiments of the present application, the following first describes a communication system applied to the embodiments of the present application.

[0067] Referring to FIG. 1, FIG. 1 is an architecture diagram of a communication system provided by an embodiment of the present application. The communication system includes, but is not limited to, one network device and one terminal device. The number and form of devices shown in FIG. 1 are exemplary and do not limit the embodiment of the present application. In practical applications, the system may include two or more network devices and two or more terminal devices. Take as an example that the communication system shown in FIG. 1 may include one network device 101 and one terminal device 102.

[0068] It should be noted that the technical solutions of the embodiments of the present application may be applied to various communication systems, such as a long term evolution (LTE) system, a 5th generation (5G) mobile communication system, a 5G new radio (NR) system, or other future new mobile communication systems.

[0069] The network device 101 in the embodiment of the present application is a network side entity for transmitting and receiving 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 embodiment of the present application does not limit the specific technology and the specific device form used by the network device. The network device provided by the embodiment of the present application is composed of a central unit (CU) and a distributed unit (DU), where the CU may be called a control unit, and the protocol layer of the network device, for example, a base station, can be separated using the CU-DU structure, and some protocol layer functions are centrally controlled by the CU, and the remaining or all protocol layer functions are distributed to the DU, and the CU centrally controls the DU.

[0070] The terminal device 102 in the embodiment of the present application is a user-side entity for transmitting and receiving signals, for example, a mobile phone. The terminal device may be called a terminal device (terminal), a user device (user equipment, UE), a mobile station (MS), a mobile terminal device (MT), etc. The terminal device may be an automobile with a communication function, a smart car, a mobile phone, a wearable device, a tablet (Pad), a computer with a wireless transmission and reception function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. The embodiment of the present application does not limit the specific technology and specific device used by the terminal device.

[0071] It should be noted that the communication system described in the embodiments of the present application is used to more clearly explain the technical solutions of the embodiments of the present application, and is not intended to limit the technical solutions provided by the embodiments of the present application. As can be understood by those skilled in the art, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present application can also be applied to similar technical issues.

[0072] In the above communication system, the calculation formula for the PDSCH processing procedure time of the terminal device is as shown in Equation (1). T proc,1 =(N1+d 1,1 )(2048+144)·κ2-μ T c (1)

[0073] Here, Tproc.1 represents the PDSCH processing procedure time of the terminal device, and the value of N1 is related to the μ value of the terminal device. There is a correspondence between the μ value and the subcarrier spacing that is determined based on the subcarrier spacing. 1,1 represents the processing time in a specific situation when the PDSCH mapping scheme is A or B, TC is the basic time unit in a communication system, and κ is defined in Article 4.1 of the 3GPP standard TS38.214.

[0074] Here, the PDSCH processing process of the terminal device includes a PDSCH decoding process and a PUCCH preparation process. Correspondingly, the PDSCH processing procedure time T proc,1 includes the PDSCH decoding time and the PUCCH preparation time, and the terminal device determines the time T proc,1 When the network device performs a time domain resource indication for HARQ-ACK feedback, it needs to consider the PDSCH decoding time and the PUCCH preparation time of the terminal device.

[0075] In Release 15, the calculation formula for the PUSCH processing procedure time of a terminal device is as shown in the following formula (2). T proc,2 =max((N2+d 2,1 )(2048+144)·κ2 -μ· T c , d 2,2 ) (2)

[0076] where T proc,2 represents the PUSCH processing procedure time of the terminal device, and the terminal device schedules the DCI after T proc,2The PUSCH can be transmitted only after receiving the PUSCH. The network device needs to consider the PUSCH processing procedure time of the terminal device when scheduling the PUSCH. 2,1 represents the processing time when the demodulation reference signal (DMRS) is set in a specific situation, and when the first symbol of the time domain resource allocated to the PUSCH contains only the DMRS, d 2,1 = 0, otherwise d 2,1 = 1, and d 2,2 represents the delay introduced in the BWP switch, and when the DCI triggers the uplink BWP switch, d 2,2 is the BWP switching delay, otherwise, d 2,2 =0.

[0077] In the above communication system, a plurality of terminal devices may access one serving cell (SC), such as a terminal device with relaxed processing capability, a terminal device with non-relaxed processing capability, etc. Different terminal devices have different PDSCH processing procedure times and PUSCH processing procedure times. For the terminal devices with the above two different processing capabilities, if the network device does not schedule all the terminal devices that access the serving cell based on the non-relaxed processing capability, the terminal device with relaxed processing capability has no time to process or prepare a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH), so that the random access message of the terminal device with relaxed processing capability is difficult to be transmitted normally.

[0078] Release 18 proposes mitigating terminal processing delays, such as PDSCH processing time (N1) and PUSCH preparation time (N2). For example, mitigating the processing delay to twice that of UE capability 1 in Release 16 will reduce terminal costs. The eRedcap project may also mitigate the PDSCH processing delay and PUSCH preparation delay for terminals of specific service types, such as non-safety sensors such as factory sensors.

[0079] In the embodiment of the present application, the terminal device UE can be divided into a terminal device with relaxed processing capability and a terminal device with non-relaxed processing capability based on the difference in channel processing delay. Note that the terminal device with relaxed processing capability refers to a terminal device with relaxed processing capability of a physical layer channel or a physical layer signal, and has a long channel processing delay. The terminal device with non-relaxed processing capability refers to a terminal device with non-relaxed processing capability of a physical layer channel or a physical layer signal, and has a short channel processing delay.

[0080] In one possible implementation, the terminal device with relaxed processing capabilities may be a terminal device with relaxed processing capabilities, also called eRedCap UE. For a terminal device with non-relaxed processing capabilities, in the embodiment of the present application, the terminal device with non-relaxed processing capabilities may also be called non-eRedCap UE. It may include at least one of a normal terminal device with reduced capabilities (RedCap UE) and a normal terminal device (called Normal UE or non-RedCap UE).

[0081] In another possible implementation, the terminal device with relaxed processing capabilities may include at least one of a reduced-capability terminal device with relaxed processing capabilities (also referred to as an eRedCap UE) and a normal terminal device with relaxed processing capabilities. The terminal device without relaxed processing capabilities may include at least one of a reduced-capability normal terminal device (RedCap UE) and a normal terminal device (also referred to as a Normal UE or non-RedCap UE).

[0082] To address this problem, the embodiments of the present application provide a terminal device scheduling method and apparatus.

[0083] Referring to Fig. 2, Fig. 2 is a flowchart of a terminal device scheduling method provided by an embodiment of the present application, and the method is executed by a terminal device. As shown in Fig. 2, the method may include, but is not limited to, the following steps 201-202:

[0086] In an embodiment of the present application, the physical layer channel / physical layer signal includes one or more of a physical random access channel (PRACH), a physical uplink shared channel (PUSCH), a physical downlink shared channel (PDSCH), a physical uplink control channel (PUCCH), a physical downlink control channel (PDCCH), a channel state information reference signal (CSI-RS), a channel sounding reference signal (SRS), a phase tracking reference signal (PTRS), and a tracking reference signal (TRS).

[0087] Here, the processing capability of the channel state information reference signal (CSI-RS) is determined by calculating the feedback of the CSI-RS, where the feedback of the CSI-RS is, for example, a precoding matrix indicator (PMI), a rank indication (RI), a channel quality indicator (CQI), etc. Here, the processing capability of the physical layer channel / signal affects the channel processing delay of the terminal device, thereby affecting the determination of the resource corresponding to the third random access message in the random access process of the terminal device, and the determination of the resource corresponding to the feedback of the fourth random access message.

[0088] In the embodiment of the present application, the random access message refers to an interaction message between a terminal device and a network device in the random access process, such as the first random access message (Msg1), the second random access message (Msg2), the third random access message (Msg3) and the fourth random access message (Msg4), etc.

[0089] In the embodiment of the present application, the resource corresponding to the random access message may include one of the following: a bandwidth portion, a random access occasion, a preamble sequence in a shared random access occasion, and a PUSCH time-frequency domain resource, where for each random access message, the resource corresponding to the random access message may be at least one of the above resources.

[0090] Step 202: sending a random access message to a network device using the resource, where the random access message sent using the resource instructs the network device to determine a random access message processing delay of a terminal device based on a resource corresponding to the random access message, where the random access message processing delay of the terminal device is used to schedule transmission of a subsequent random access message of the terminal device.

[0091] In the embodiment of the present application, after determining its own physical layer channel / signal processing capability, the terminal device determines a resource for transmitting a random access message, and sends the random access message to a network device through the resource. Wherein, the random access message sent using the resource instructs the network device to determine a random access message processing delay of the terminal device according to a resource corresponding to the random access message, and correspondingly and reasonably schedules the transmission of the subsequent random access message of the terminal device. That is, according to the method on the terminal device side, after receiving the random access message sent using the resource, the network device may perform the following operations according to the random access message sent using the resource: Determine a random access message processing delay of the terminal device according to the resource for transmitting the random access message, and thereby reasonably schedule the transmission of the subsequent random access message of the terminal device.

[0092] Wherein, the terminal device with relaxed processing capability and the terminal device with non-relaxed processing capability can use different resources to send random access messages. Corresponding to the method on the terminal device side, after receiving the random access message sent using the resource, the network device can perform the following operations according to the random access message sent using the resource: According to the resource receiving the random access message, determine the type of the terminal device sending the random access message, or determine the processing capability of the terminal device sending the random access message, and correspondingly determine the random access message processing delay of the terminal device.

[0093] Here, the terminal device with relaxed processing capability and the terminal device with non-relaxed processing capability may use different resources to transmit a random access message. In one example, the terminal device with relaxed processing capability uses a first bandwidth portion BWP resource, and the terminal device with non-relaxed processing capability uses a second bandwidth portion BWP resource, where the first BWP resource and the second BWP resource only partially overlap or do not overlap at all. Here, only partially overlapping refers to a part of the first BWP resource overlapping with a part of the second BWP resource. In another example, the terminal device with relaxed processing capability uses a preamble sequence in a first preamble sequence set, and the terminal device with non-relaxed processing capability uses a preamble sequence in a second preamble sequence set, where the first preamble sequence set and the second preamble sequence set have no common set. Detailed description is omitted in the embodiment of the present application.

[0094] By implementing the embodiment of the present application, a terminal device can determine a resource for transmitting a random access message based on the processing capability of its own physical layer channel / signal, and use the resource to send the random access message to a network device, where the random access message sent using the resource instructs the network device to determine a random access message processing delay of the terminal device based on a resource corresponding to the random access message, and the random access message processing delay of the terminal device schedules the transmission of a subsequent random access message of the terminal device. In this manner, the network device can allocate different resources for subsequent random access messages to terminal devices with different processing capabilities, so that the terminal device can successfully transmit a message through the reasonably allocated resource, and avoid re-scheduling of resources when a message transmission fails, thereby avoiding resource waste and improving resource utilization rate.

[0095] Referring to Fig. 3, Fig. 3 is a flowchart of a terminal device scheduling method provided by an embodiment of the present application, and the method is executed by a terminal device. As shown in Fig. 3, the method may include, but is not limited to, the following steps 301 to 303.

[0096] Step 301: receive information sent from a network device, where according to the information, the terminal device determines candidate resource groups corresponding to at least two terminal devices. In some possible implementations, the information may be configuration signaling or configuration parameters, or may be indication information.

[0097] In the embodiment of the present application, different terminal devices correspond to different candidate resource groups, where different terminal devices refer to terminal devices having different processing capabilities of physical layer channels or terminal devices having different processing capabilities of physical layer signals.

[0098] Step 302: determine a candidate resource group corresponding to the terminal device for sending a random access message, and a resource in the candidate resource group is a resource corresponding to the random access message.

[0099] In the embodiments of the present application, the processing capability of the physical layer channel / signal of the terminal device refers to the processing capability of the physical layer channel or the processing capability of the physical layer signal of the terminal device.

[0100] In the above steps 301 and 302, the terminal device can determine the mapping relationship between the candidate resource groups and the terminal device type according to the received information. Here, the terminal device type refers to the terminal device having different processing capabilities of the physical layer channels or the terminal device having different processing capabilities of the physical layer signals. The terminal device can determine the candidate resource groups corresponding to the terminal device according to the processing capabilities of its own physical layer channels or the processing capabilities of its own physical layer signals.

[0101] In the above steps 301 and 302, the terminal device can further determine a mapping relationship between the candidate resource groups and the terminal device type according to a protocol or pre-configuration information. Here, the terminal device type refers to the terminal device having different processing capabilities of the physical layer channels or the terminal device having different processing capabilities of the physical layer signals. The terminal device can determine the candidate resource groups corresponding to the terminal device according to the processing capabilities of its own physical layer channels or the processing capabilities of its own physical layer signals.

[0102] In all embodiments of the present application, a candidate resource group may include one or more candidate resources.

[0103] In an embodiment of the present application, the terminal device determines, based on the received information, a mapping relationship between terminal devices with different processing capabilities and different candidate resource groups for a random access message, and, based on the processing capability of its own physical layer channel / the processing capability of its own physical layer signal, can determine a candidate resource group with a mapping relationship between the processing capability of its own physical layer channel / the processing capability of its own physical layer signal, i.e., a candidate resource group for transmitting a random access message, thereby using resources in the candidate resource group to transmit the random access message to a network device.

[0104] In an embodiment of the present application, the physical layer channel / physical layer signal includes one or more of a physical random access channel (PRACH), a physical uplink shared channel (PUSCH), a physical downlink shared channel (PDSCH), a physical uplink control channel (PUCCH), a physical downlink control channel (PDCCH), a channel state information reference signal (CSI-RS), a channel sounding reference signal (SRS), a phase tracking reference signal (PTRS), and a tracking reference signal (TRS).

[0105] In an embodiment of the present application, in response to the terminal device being an evolved capability-reduced terminal device (i.e., an eRedCap UE), or in response to the processing capability of the physical layer channel of the terminal device or the processing capability of the physical layer signal of the terminal device being a relaxed processing capability, determine a candidate resource group for the terminal device based on a mapping relationship between the candidate resource group and the processing capability of the physical layer channel of the terminal device or the processing capability of the physical layer signal of the terminal device, and determine a resource for transmitting a random access message from the candidate resource group of the terminal device, where the same candidate resource does not exist in different candidate resource groups.

[0106] In all embodiments of the present application, a candidate resource group may include one or more candidate resources.

[0107] In one example, in response to the terminal device being an evolved reduced-capability terminal device, determine a candidate resource group based on a mapping relationship between the candidate resource group and the evolved reduced-capability terminal device, and determine a resource from the candidate resource group for transmitting the random access message, where the evolved reduced-capability terminal device may be a terminal device with relaxed processing capability.

[0108] In another example, in response to the processing capability of the physical layer channel of the terminal device or the processing capability of the physical layer signal of the terminal device being a relaxed processing capability, a candidate resource group is determined based on a mapping relationship between the candidate resource group and the processing capability of the physical layer channel of the terminal device or the processing capability of the physical layer signal of the terminal device, and a resource for transmitting the random access message is determined from the candidate resource group. Here, the terminal device with relaxed processing capability may be a reduced-capability terminal device with relaxed processing capability. In another example, in response to the terminal device being a terminal device with relaxed processing capability, a candidate resource group is determined based on a mapping relationship between the candidate resource group and a terminal device type, and a resource for transmitting the random access message is determined from the candidate resource group.

[0109] Step 303: sending a random access message to a network device using the resource, where the random access message sent using the resource instructs the network device to determine a random access message processing delay of a terminal device based on a resource corresponding to the random access message, where the random access message processing delay of the terminal device is used to schedule transmission of a subsequent random access message of the terminal device.

[0110] In the embodiment of the present application, the terminal device determines a candidate resource group for sending the random access message according to the processing capability of its own physical layer channel or the processing capability of its own physical layer signal, and the resource in the candidate resource group is the resource corresponding to the random access message, and sends the random access message to the network device through the resource. Corresponding to the method on the terminal device side, after receiving the random access message, the network device determines the random access message processing delay of the terminal device according to the resource that transmits the random access message, and reasonably schedules the transmission of the subsequent random access message of the terminal device.

[0111] In some possible implementations, the random access message may be a first random access message (Msg1) and a third random access message (Msg3). Here, in one example, the random access message may be the first random access message (Msg1), and the terminal device reports the processing capability of the physical layer channel or the processing capability of the physical layer signal of the terminal device by setting different resources for the first random access message. The subsequent random access message related to the network device scheduling the terminal device refers to the feedback of the third random access message and the fourth random access message. In another example, the random access message may be the third random access message (Msg3), and the terminal device reports the processing capability of the physical layer channel of the terminal device or the processing capability of its own physical layer signal by setting different resources for the third random access message. The subsequent random access message related to the network device scheduling the terminal device refers to the feedback of the fourth random access message.

[0112] By implementing the embodiment of the present application, a terminal device can receive information sent from a network device, where the information is used to determine a candidate resource group corresponding to the terminal device, and the terminal device determines a candidate resource group of a random access message corresponding to the terminal device based on the information based on the processing capability of its own physical layer channel or the processing capability of its own physical layer signal, and the terminal device further determines a candidate resource group for transmitting the random access message from the candidate resource group, and uses resources in the candidate resource group to transmit the random access message to the network device, so that the network device determines the random access message processing delay of the terminal device based on the transmission resource of the random access message, and schedules the transmission of the subsequent random access message of the terminal device. In this manner, the terminal device can select resources from the corresponding candidate resource group to transmit the random access message based on the processing capability of its own physical layer channel or the processing capability of its own physical layer signal, so that the network device can determine the processing capability of the terminal device based on the resource for transmitting the random access message, and further performs resource scheduling processing for the transmission of the subsequent random access message of the terminal device, avoiding resource waste and improving resource utilization. Of course, the terminal device can further determine the candidate resource groups corresponding to the terminal device based on the communication protocol.

[0113] In the above embodiment, the random access message may be the first random access information (Msg1), that is, the method may include steps 401 to 403, as shown in FIG.

[0114] Step 401: receive information sent from a network device, where according to the information, the terminal device determines candidate resource groups corresponding to at least two terminal devices. In some possible implementations, the information may be configuration signaling or configuration parameters, or may be indication information.

[0115] In the embodiment of the present application, different terminal devices correspond to different candidate resource groups, where different terminal devices refer to terminal devices having different processing capabilities of physical layer channels or terminal devices having different processing capabilities of physical layer signals.

[0116] Step 402: determine a candidate resource group for sending a first random access message corresponding to the terminal device, and a resource in the candidate resource group is a resource corresponding to the first random access message.

[0117] In the embodiments of the present application, the processing capability of the physical layer channel / signal of the terminal device refers to the processing capability of the physical layer channel or the processing capability of the physical layer signal of the terminal device.

[0118] In the above steps 401 and 402, the terminal device can determine the mapping relationship between the candidate resource groups and the terminal device type according to the received information. Here, the terminal device type refers to the terminal device having different processing capabilities of the physical layer channels or the terminal device having different processing capabilities of the physical layer signals. The terminal device can determine the candidate resource groups corresponding to the terminal device according to the processing capabilities of its own physical layer channels or the processing capabilities of its own physical layer signals.

[0119] In the above steps 401 and 402, the terminal device can also determine a mapping relationship between the candidate resource groups and the terminal device type according to a protocol or pre-configuration information. Here, the terminal device type refers to the terminal device having different processing capabilities of the physical layer channels or the terminal device having different processing capabilities of the physical layer signals. The terminal device can determine the candidate resource groups corresponding to the terminal device according to the processing capabilities of its own physical layer channels or the processing capabilities of its own physical layer signals.

[0120] In all embodiments of the present application, a candidate resource group may include one or more candidate resources.

[0121] Step 403: sending a first random access message to a network device using a resource, where the first random access message sent using the resource instructs the network device to determine a random access message processing delay of the terminal device based on a resource corresponding to the first random access message, and schedule transmission of a subsequent random access message of the terminal device.

[0122] In the embodiment of the present application, the terminal device determines that its own physical layer channel processing capability or physical layer signal processing capability is different, determines a candidate resource group for sending a first random access message, and takes a resource in the candidate resource group as a resource corresponding to the first random access message, and sends the first random access message to the network device through the resource. Corresponding to the method at the terminal device side, after the network device receives the first random access message, determines the random access message processing delay of the terminal device according to the resource for transmitting the first random access message, thereby reasonably scheduling the transmission of the subsequent random access message of the terminal device.

[0123] Here, when the random access message is the first random access message (Msg1), the terminal device can report the processing capability of the physical layer channel / signal of the terminal device by configuring different resources for the first random access message, so that the subsequent random access messages related to the network device scheduling the terminal device refer to the feedback of the third random access message and the fourth random access message.

[0124] Referring to Fig. 5, Fig. 5 is a flowchart of a terminal device scheduling method provided by an embodiment of the present application, and the method is executed by a terminal device. As shown in Fig. 5, the method may include, but is not limited to, the following steps 501-503.

[0125] Step 501, the terminal device determines a first time interval corresponding to the processing capability of the terminal device physical layer channel or the processing capability of the terminal device physical layer signal, where the first time interval is a time interval from when the terminal device receives the last symbol of the second random access message to when the terminal device sends the first symbol of the third random access message.

[0126] In an embodiment of the present application, the terminal device can determine a corresponding first time interval based on the received information. In an embodiment of the present application, the information received by the terminal device can be configuration information or indication information, and the information is used to configure or indicate a first time interval corresponding to at least two different terminal device types. Here, the terminal device type refers to the different processing capabilities of the physical layer channels of the terminal devices or the different processing capabilities of the physical layer signals of the terminal devices. After receiving the information, the terminal device can determine a candidate resource group corresponding to the terminal device based on its terminal device type. Here, the terminal device type refers to the different processing capabilities of the physical layer channels of the terminal devices or the different processing capabilities of the physical layer signals of the terminal devices. The terminal device can determine a first time interval corresponding to the terminal device based on the processing capabilities of its own physical layer channels or the processing capabilities of its own physical layer signals.

[0127] In a first type of example, the information includes first time intervals corresponding to at least two types of terminal device types, so that the terminal device can determine the corresponding first time intervals based on the terminal device type and the information to facilitate determining resources for transmitting the third random access message Msg3, where the terminal device type includes at least one of a relaxed terminal device and a non-relaxed terminal device. In all embodiments of the present application, the processing capability of the physical layer channel of the relaxed terminal device or the processing capability of the physical layer signal of the relaxed terminal device is different from the processing capability of the physical layer channel of the non-relaxed terminal device or the processing capability of the physical layer signal of the non-relaxed terminal device.

[0128] In a second type of example, the information includes an index of a first time interval corresponding to each of at least two terminal device types. The terminal device can determine the first time interval corresponding to at least the terminal device type based on the index of the first time interval corresponding to each of at least two terminal device types, and further determines a mapping relationship between the candidate resource group and the terminal device type based on the first time interval corresponding to each of the at least two terminal device types, and further selects a resource for transmitting the corresponding third random access message Msg3 based on its own terminal device type. The terminal device type includes at least one of a terminal device with relaxed processing capability and a terminal device with non-relaxed processing capability. In all embodiments of the present application, the processing capability of the physical layer channel of the terminal device with relaxed processing capability or the processing capability of the physical layer signal of the terminal device with relaxed processing capability is different from the processing capability of the physical layer channel of the terminal device with non-relaxed processing capability or the processing capability of the physical layer signal of the terminal device with non-relaxed processing capability.

[0129] In the above two examples, the network device may directly indicate the first time intervals corresponding to the two terminal device types, or may indicate the indexes of the first time intervals.

[0130] In a third type of example, the information includes a parameter for determining a first time interval of a non-relaxed terminal device and a parameter value N for determining a first time interval of a relaxed terminal device. In response to the terminal device being a non-relaxed terminal device, the terminal device may determine the first time interval of the non-relaxed terminal device based on the parameter for determining the first time interval of the non-relaxed terminal device included in the information, where the parameter for determining the first time interval of the non-relaxed terminal device may be a numerical value of the first time interval, or may be an index of the first time interval, or may be a parameter for calculating the first time interval.

[0131] In response to the terminal device being a terminal device with a relaxed processing capability, the terminal device with a relaxed processing capability can determine a first time interval of the terminal device with a relaxed processing capability based on the parameter for determining a first time interval of the terminal device with a non-relaxed processing capability and the parameter value N. In response to the terminal device being determined or the terminal device being a terminal device with a non-relaxed processing capability, the terminal device with a relaxed processing capability can determine a first time interval corresponding to the terminal device with a relaxed processing capability based on the parameter for determining a first time interval of the terminal device with a non-relaxed processing capability, the parameter value N, and a calculation rule. The calculation rule may be any rule and is not limited here. Take the calculation rule as an example that +, the calculation formula of the first time interval (K_new) corresponding to the terminal device with a relaxed processing capability can be K_new=K+N, where K is the first time interval of the terminal device with a non-relaxed processing capability, that is, the first time interval of the terminal device with a relaxed processing capability is equal to the first time interval of the terminal device with a non-relaxed processing capability+the parameter value N. For example, the calculation rule is *, and the calculation formula of the first time interval (K_new) of the terminal device with relaxed processing power may be K_new=K*N. Here, the calculation rule may be a preset rule, or may be a rule determined based on a communication protocol, or may be a rule set by a network device, etc.

[0132] After the terminal device determines the corresponding first time interval, it may further transmit a third random access message Msg3 in the corresponding resource.

[0133] In a fourth type of example, the information carries index information for determining a first time interval in which the processing capability is not relaxed. Furthermore, the terminal with relaxed processing capability determines a first time interval corresponding to itself based on the first time interval corresponding to the terminal with non-relaxed processing capability and a calculation rule, and transmits a third random access message Msg3 in the corresponding resource. Here, taking the calculation rule as + for example, the calculation formula of the first time interval (K_new) corresponding to the terminal device with relaxed processing capability may be K_new=K+N. Taking the calculation rule as * for example, the calculation formula of the first time interval (K_new) of the terminal device with relaxed processing capability may be K_new=K*N. Here, K is the first time interval of the terminal device with non-relaxed processing capability, K_new is the first time interval of the terminal device with relaxed processing capability, and the value of N is a parameter value preset in the protocol. Here, the calculation rule may be a preset rule, or may be a rule determined based on a communication protocol, or may be a rule set by a network device, etc. Here, the parameter value N may be a preset value, or may be a value determined by a communication protocol.

[0134] Step 502: determine a candidate resource group for sending a third random access message according to a terminal device type, and a resource in the candidate resource group is a resource corresponding to the third random access message.

[0135] In an embodiment of the present application, the terminal device can determine a first time interval corresponding to a different terminal type based on the received information, and can further determine a resource for transmitting a third random access message in combination with the processing capability of its own physical layer channel or the processing capability of a physical layer signal, and use the resource to send the third random access message to the network device.

[0136] In an embodiment of the present application, the physical layer channel / physical layer signal includes one or more of a physical random access channel (PRACH), a physical uplink shared channel (PUSCH), a physical downlink shared channel (PDSCH), a physical uplink control channel (PUCCH), a physical downlink control channel (PDCCH), a channel state information reference signal (CSI-RS), a channel sounding reference signal (SRS), a phase tracking reference signal (PTRS), and a tracking reference signal (TRS).

[0137] Step 503: sending a third random access message to a network device using a resource, where the third random access message sent using the resource instructs the network device to determine a random access message processing delay of the terminal device based on a resource corresponding to the third random access message, and schedule transmission of a subsequent random access message of the terminal device.

[0138] In the embodiment of the present application, the terminal device determines the processing capability of its own physical layer channel or the processing capability of the physical layer signal, and then determines a candidate resource group for transmitting the third random access message, and the resource in the candidate resource group is the resource corresponding to the third random access message, and transmits the third random access message to the network device through the resource. Corresponding to the method on the terminal device side, after the network device receives the third random access message, it determines the random access message processing delay of the terminal device according to the resource transmitting the third random access message, and reasonably schedules the transmission of the subsequent random access message of the terminal device. Here, the candidate resource group of the third random access message may include only one resource used for transmitting the third random access message (Msg3).

[0139] Here, when the random access message may be a third random access message (Msg3), the terminal device can report the processing capability of the physical layer channel or the processing capability of the physical layer signal of the terminal device by configuring different resources for the third random access message. Therefore, the subsequent random access message related to the network device scheduling the terminal device refers to the feedback of the fourth random access message.

[0140] By implementing the embodiment of the present application, the terminal device determines a first time interval corresponding to a processing capability of a physical layer channel or a processing capability of a terminal device physical layer signal, where the first time interval is a time interval from when the terminal device receives the last symbol of the second random access message to when the terminal device sends the first symbol of the third random access message; determine a candidate resource group for sending the third random access message based on a terminal device type, and use the resource in the candidate resource group to send the third random access message to the network device; and according to the method on the terminal device side, the network device sends the third random access message to the network device using the resource. According to the resource corresponding to the third random access message, determine the random access message processing delay of the terminal device, and schedule the transmission of the subsequent random access message of the terminal device. In this manner, the terminal device can select a resource from the corresponding candidate resource group to transmit the third random access message based on the processing capability of its own physical layer channel or the processing capability of the physical layer signal, so that the network device can determine the processing capability of the terminal device based on the resource for transmitting the third random access message, and perform resource scheduling processing for the transmission of the subsequent random access message of the terminal device, to avoid resource waste and improve resource utilization rate.

[0141] Referring to Fig. 6, Fig. 6 is a flowchart of a terminal device scheduling method provided by an embodiment of the present application, and the method is executed by a network device. As shown in Fig. 6, the method may include, but is not limited to, the following steps 601 to 603:

[0142] Step 601, receive a random access message sent from a terminal device.

[0143] In the embodiments of the present application, the random access message refers to an interaction message between a terminal device and a network device during random access, such as a first random access message (Msg1), a second random access message (Msg2), a third random access message (Msg3) and a fourth random access message (Msg4).

[0144] Wherein, in accordance with the method on the network device side, when the terminal device sends a random access message, it implicitly reports the processing capability of the physical layer channel / signal of the terminal device by sending a resource of the random access message, that is, it implicitly reports whether the terminal device is a terminal device with relaxed processing capability or a terminal device with non-relaxed processing capability. The network device can determine the random access message processing delay of the terminal device according to the received random access message. Wherein, the resource may include at least one of a bandwidth portion, a random access occasion, a preamble sequence in a shared random access occasion, and a PUSCH time-frequency domain resource. Wherein, the processing capability of the physical layer channel / signal of the terminal device refers to the processing capability of the physical layer channel of the terminal device or the processing capability of the physical layer signal of the terminal device.

[0145] Here, the resource for the terminal device to transmit the random access message is determined according to the processing capability of the physical layer channel or the processing capability of the physical layer signal of the terminal device itself. There is a corresponding relationship between the resource for transmitting the random access message and the processing capability of the physical layer channel or the processing capability of the physical layer signal, and the network device can determine the processing capability of the physical layer channel / physical layer signal of the terminal device according to the resource for transmitting the random access message.

[0146] Step 602, determine a random access message processing delay of a terminal device according to resources corresponding to the random access message.

[0147] In an embodiment of the present application, the resource corresponding to the random access message may include one of a bandwidth portion, a random access occasion, a preamble sequence in a shared random access occasion, and a PUSCH time-frequency domain resource.

[0148] In the embodiment of the present application, according to the method of the network device side, when the terminal device sends a random access message, it will send the resource of the random access message to implicitly report the processing capability of the physical layer channel / signal of the terminal device, that is, whether the terminal device is a terminal device with relaxed processing capability or a terminal device with non-relaxed processing capability. Therefore, after receiving the random access message sent by the terminal device, the network device can determine the processing capability of the physical layer channel or the processing capability of the physical layer signal of the terminal device according to the resource after determining that the resource of the random access message is received, and can determine the random access message processing delay of the terminal device according to the processing capability of the physical layer channel or the processing capability of the physical layer signal of the terminal device.

[0149] Here, the terminal device with relaxed processing capabilities and the terminal device with non-relaxed processing capabilities may send random access messages using different resources, and after receiving the random access message sent using the resources, the network device can determine the type of the terminal device sending the random access message or the processing capability of the terminal device sending the random access message based on the random access message sent using the resources, and correspondingly determine the random access message processing delay of the terminal device.

[0150] Here, the terminal device with relaxed processing capability and the terminal device with non-relaxed processing capability can use different resources to transmit a random access message. In one example, the terminal device with relaxed processing capability uses a first bandwidth portion BWP resource, and the terminal device with non-relaxed processing capability uses a second bandwidth portion BWP resource, where the first BWP resource and the second BWP resource only partially overlap or do not overlap at all. Here, only partially overlapping refers to a part of the first BWP resource overlapping with a part of the second BWP resource. In another example, the terminal device with relaxed processing capability uses a preamble sequence in a first preamble sequence set, and the terminal device with non-relaxed processing capability uses a preamble sequence in a second preamble sequence set, where the first preamble sequence set and the second preamble sequence set have no intersection. Detailed description is omitted in the embodiments of the present application.

[0151] Step 603: Schedule transmission of subsequent random access messages of the terminal device according to the random access message processing delay of the terminal device.

[0152] In an embodiment of the present application, after receiving a random access message, the network device determines a random access message processing delay of the terminal device based on the resource for transmitting the random access message, and further reasonably schedules the transmission of subsequent random access messages of the terminal device.

[0153] Here, the random access message may be a first random access message (Msg1) and a third random access message (Msg3). Here, in one example, the random access message may be a first random access message (Msg1), and corresponding to the method on the network device side, the terminal device reports the processing capability of the physical layer channel / signal of the terminal device by setting different resources for the first random access message, and the subsequent random access message related to the network device scheduling the terminal device refers to the feedback of the third random access message and the fourth random access message. In another example, the random access message may be a third random access message (Msg3), and corresponding to the method on the network device side, the terminal device reports the processing capability of the physical layer channel / signal of the terminal device by setting resources for the third random access message, and the subsequent random access message related to the network device scheduling the terminal device refers to the feedback of the fourth random access message. Here, the processing capability of the physical layer channel / signal of the terminal device refers to the processing capability of the physical layer channel of the terminal device or the processing capability of the physical layer signal of the terminal device.

[0154] By implementing the embodiment of the present application, a random access message sent from a terminal device is received, and a random access message processing delay of the terminal device is determined based on a resource corresponding to the random access message, and a transmission of a subsequent random access message of the terminal device is scheduled based on the random access message processing delay of the terminal device. In this manner, the network device can allocate different resources for subsequent random access messages to terminal devices with different processing capabilities, so that the terminal device can successfully transmit a message through the reasonably allocated resources, and avoid re-scheduling of resources when a message transmission fails, avoiding resource waste, and improving resource utilization rate.

[0155] Referring to Fig. 7, Fig. 7 is a flowchart of a terminal device scheduling method provided by an embodiment of the present application, and the method is executed by a network device. As shown in Fig. 7, the method may include, but is not limited to, the following steps 701-704:

[0156] Step 701: Send information to a terminal device, where the information indicates candidate resource groups corresponding to at least two terminal devices. In some possible implementations, the information may be configuration signaling or configuration parameters, or may be indication information.

[0157] In the embodiment of the present application, different terminal devices correspond to different candidate resource groups, where different terminal devices refer to terminal devices having different processing capabilities of physical layer channels or terminal devices having different processing capabilities of physical layer signals.

[0158] In the embodiments of the present application, the processing capability of a physical layer channel / signal of a terminal device refers to the processing capability of a physical layer channel of a terminal device or the processing capability of a physical layer signal of a terminal device.

[0159] In an embodiment of the present application, the physical layer channel / physical layer signal includes one or more of a physical random access channel (PRACH), a physical uplink shared channel (PUSCH), a physical downlink shared channel (PDSCH), a physical uplink control channel (PUCCH), a physical downlink control channel (PDCCH), a channel state information reference signal (CSI-RS), a channel sounding reference signal (SRS), a phase tracking reference signal (PTRS), and a tracking reference signal (TRS).

[0160] In the embodiment of the present application, the random access messages may be a first random access message (Msg1) and a third random access message (Msg3).

[0161] When the random access message is a first random access message (Msg1), a mapping relationship between a terminal device type and a candidate resource group is preset, where the terminal device type refers to the terminal device having different physical layer channel processing capabilities or the terminal device having different physical layer signal processing capabilities.

[0162] In an embodiment of the present application, when the random access message is a third random access message (Msg3), the mapping relationship between the candidate resource group and the terminal device type is determined based on a first time interval corresponding to the processing capabilities of at least two types of physical layer channels / signals, where the first time interval is the time interval from when the terminal device receives the last symbol of the second random access message to when it sends the first symbol of the third random access message.

[0163] Here, the information may be configuration information or indication information, and the manner in which the information configures or indicates candidate resource groups corresponding to at least two different terminal device types may be various.

[0164] In a first example, the information includes first time intervals corresponding to at least two terminal device types, so that the terminal device can easily determine the corresponding first time intervals based on the terminal device type and the information to easily determine the resources for transmitting the third random access message Msg3. Here, the terminal device type includes at least one of a relaxed terminal device and a non-relaxed terminal device. In all embodiments of the present application, the processing capability of the physical layer channel of the relaxed terminal device or the processing capability of the physical layer signal of the relaxed terminal device is different from the processing capability of the physical layer channel of the non-relaxed terminal device or the processing capability of the physical layer signal of the non-relaxed terminal device.

[0165] In the embodiments of the present application, the processing capability of a physical layer channel / signal of a terminal device refers to the processing capability of a physical layer channel of a terminal device or the processing capability of a physical layer signal of a terminal device.

[0166] In a second type of example, the information includes an index of a first time interval corresponding to each of at least two terminal device types. The terminal device can determine at least a first time interval corresponding to a terminal device type based on an index of a first time interval corresponding to each of at least two terminal device types, and further determines a mapping relationship between a candidate resource group and a terminal device type based on the first time interval corresponding to each of the terminal device types, and further selects a resource for transmitting a corresponding third random access message Msg3 based on its own terminal device type. The terminal device type includes at least one of a terminal device with relaxed processing capability and a terminal device with non-relaxed processing capability. In all embodiments of the present application, the processing capability of a physical layer channel of the terminal device with relaxed processing capability or the processing capability of a physical layer signal of the terminal device with relaxed processing capability is different from the processing capability of a physical layer channel of a terminal device with non-relaxed processing capability or the processing capability of a physical layer signal of a terminal device with non-relaxed processing capability.

[0167] In the above two examples, the first time intervals corresponding to the two terminal device types are included or the index of the first time interval can be directly indicated via the network device.

[0168] In a third type of example, the information includes a parameter for determining a first time interval of a non-relaxed terminal device and a parameter value N for determining a first time interval of a relaxed terminal device. In response to the terminal device being a non-relaxed terminal device, the terminal device may determine the first time interval of the non-relaxed terminal device based on the parameter for determining the first time interval of the non-relaxed terminal device included in the information, where the parameter for determining the first time interval of the non-relaxed terminal device may be a numerical value of the first time interval, or may be an index of the first time interval, or may be a parameter for calculating the first time interval.

[0169] In response to the terminal device being a terminal device with a relaxed processing capability, the terminal device with a relaxed processing capability can determine a first time interval of the terminal device with a relaxed processing capability based on the parameter for determining a first time interval of the terminal device with a non-relaxed processing capability and the parameter value N. In response to the terminal device being determined or the terminal device being a terminal device with a non-relaxed processing capability, the terminal device with a relaxed processing capability can determine a first time interval corresponding to the terminal device with a relaxed processing capability based on the parameter for determining a first time interval of the terminal device with a non-relaxed processing capability, the parameter value N, and a calculation rule. The calculation rule may be any rule and is not limited here. Take the calculation rule as an example that +, the calculation formula of the first time interval (K_new) corresponding to the terminal device with a relaxed processing capability can be K_new=K+N, where K is the first time interval of the terminal device with a non-relaxed processing capability, that is, the first time interval of the terminal device with a relaxed processing capability is equal to the first time interval of the terminal device with a non-relaxed processing capability+the parameter value N. For example, the calculation rule is *, and the calculation formula of the first time interval (K_new) of the terminal device with relaxed processing power may be K_new=K*N. Here, the calculation rule may be a preset rule, or may be a rule determined based on a communication protocol, or may be a rule set by a network device, etc.

[0170] After the terminal device determines the corresponding first time interval, it may further transmit a third random access message Msg3 in the corresponding resource.

[0171] In a fourth type of example, the information carries index information for determining a first time interval in which the processing capability is not relaxed. Furthermore, the terminal with relaxed processing capability determines a first time interval corresponding to itself based on the first time interval corresponding to the terminal with non-relaxed processing capability and a calculation rule, and transmits a third random access message Msg3 in the corresponding resource. Here, taking the calculation rule as + for example, the calculation formula of the first time interval (K_new) corresponding to the terminal device with relaxed processing capability may be K_new=K+N. Taking the calculation rule as * for example, the calculation formula of the first time interval (K_new) of the terminal device with relaxed processing capability may be K_new=K*N. Here, K is the first time interval of the terminal device with non-relaxed processing capability, K_new is the first time interval of the terminal device with relaxed processing capability, and the value of N is a parameter value preset in the protocol. Here, the calculation rule may be a preset rule, or may be a rule determined based on a communication protocol, or may be a rule set by a network device, etc. Here, the parameter value N may be a preset value, or may be a value determined by a communication protocol.

[0172] In the embodiment of the present application, there are three types of time intervals. One is the minimum time interval between the terminal device receiving the second random access message and sending a new first random access message, the other is the minimum time interval between the terminal device receiving the second random access message and sending a third random access message, that is, the first time interval in each embodiment of the present application, and the third type is the minimum time interval between the terminal device receiving the fourth random access message and sending a HARQ-ACK feedback message. Here, terminal devices with different processing capabilities have different time intervals.

[0173] For example, for a terminal device with non-restricted processing power, the calculation policies of the above three types of time intervals may be as shown in the following Table 1. For a terminal device with relaxed processing power, the calculation policies of the above three types of time intervals may be as shown in the following Table 2.

[0174] [Table 1]

[0175] Here, in Table 1, NT,1 and NT,2 respectively represent N1 and N2 in the PDSCH processing procedure time calculation formula of a terminal device whose processing capability is not relaxed.

[0176] [Table 2]

[0177] Here, in Table 2, NT,1 and NT,2 respectively represent N1 and N2 in the PDSCH processing procedure time calculation formula for a terminal device with relaxed processing capabilities, Msg1 is the first random access message, Msg2 is the second random access message, Msg3 is the third random access message, Msg4 is the fourth random access message, and 0.5 is the processing time of Msg2 in the media access control (MAC) layer.

[0178] Step 702, receive a random access message sent from a terminal device.

[0179] In the embodiments of the present application, the random access message refers to an interaction message between a terminal device and a network device during random access, such as a first random access message (Msg1), a second random access message (Msg2), a third random access message (Msg3) and a fourth random access message (Msg4).

[0180] Wherein, corresponding to the method on the network device side, when the terminal device sends a random access message, it implicitly reports the processing capability of the physical layer channel or the processing capability of the physical layer signal of the terminal device through the resource for sending the random access message, that is, it implicitly reports whether the terminal device is a terminal device with relaxed processing capability or a terminal device with non-relaxed processing capability, so that it is easy for the network device to determine the random access message processing delay of the terminal device. Wherein, the resource may include one of the following: a bandwidth portion, a random access occasion, a preamble sequence in a shared random access occasion, and a PUSCH time-frequency domain resource. Wherein, the processing capability of the physical layer channel / signal of the terminal device refers to the processing capability of the physical layer channel of the terminal device or the processing capability of the physical layer signal of the terminal device.

[0181] Here, the resource that the terminal device uses to send the random access message is determined by the processing capability of the physical layer channel or the processing capability of the physical layer signal of the terminal device itself. There is a corresponding relationship between the resource that the random access message is sent from and the processing capability of the physical layer channel or the processing capability of the physical layer signal, and the network device can determine the processing capability of the physical layer channel or the processing capability of the physical layer signal of the terminal device based on the resource that the terminal device uses to send the random access message.

[0182] Step 703, determine a random access message processing delay of a terminal device according to a resource corresponding to the random access message.

[0183] In an embodiment of the present application, in response to the resource corresponding to the random access message being a configured resource in at least two candidate resource groups, determine that the random access message processing delay of the terminal device is a relaxed delay, i.e., the random access message processing delay of a terminal device with relaxed processing capability; in response to the resource corresponding to the random access message being a non-configured resource in at least two candidate resource groups, determine that the random access message processing delay of the terminal device is a non-relaxed delay, i.e., the random access message processing delay of a terminal device with non-relaxed processing capability.

[0184] Step 704: Schedule transmission of a subsequent random access message of the terminal device based on the random access message processing delay of the terminal device.

[0185] In an embodiment of the present application, after receiving a random access message, the network device determines a random access message processing delay of the terminal device based on the resource for transmitting the random access message, and further reasonably schedules the transmission of subsequent random access messages of the terminal device.

[0186] Here, the random access message may be a first random access message (Msg1) and a third random access message (Msg3). Here, in one example, the random access message may be a first random access message (Msg1), and corresponding to the method on the network device side, the terminal device reports the processing capability of the physical layer channel or the processing capability of the physical layer signal of the terminal device by setting different resources for the first random access message, and the subsequent random access message related to the network device scheduling the terminal device refers to the feedback of the third random access message and the fourth random access message. In another example, the random access message may be a third random access message (Msg3), and corresponding to the method on the network device side, the terminal device reports the processing capability of the physical layer channel or the processing capability of the physical layer signal of the terminal device by setting different resources for the third random access message, and the subsequent random access message related to the network device scheduling the terminal device refers to the feedback of the fourth random access message.

[0187] By implementing the embodiment of the present application, the network device sends information to the terminal device, where the information indicates candidate resource groups corresponding to at least two kinds of terminal devices, receives a random access message sent from the terminal device, determines a random access message processing delay of the terminal device according to the resource corresponding to the random access message, and schedules the transmission of a subsequent random access message of the terminal device according to the random access message processing delay of the terminal device. In this manner, the network device can allocate different resources for subsequent random access messages to terminal devices with different processing capabilities, so that the terminal device can successfully transmit a message with the reasonably allocated resources, avoiding re-scheduling of resources when message transmission fails, avoiding resource waste, and improving resource utilization rate.

[0188] 8, which is a flowchart of a terminal device scheduling method provided by an embodiment of the present application, the method being executed by a network device. As shown in FIG. 8, the method may include, but is not limited to, the following step 801:

[0189] Step 801, based on a mitigated random access message processing delay of the terminal device, schedule transmission of a subsequent random access message of the terminal device in a serving cell in which the network device is located.

[0190] In the embodiment of the present application, the random access message processing delay refers to the time required for a terminal device to process a random access message based on the processing capability of its own physical layer channel or the processing capability of its physical layer signal, where the random access message refers to an interaction message between a terminal device and a network device during random access, such as the first random access message (Msg1), the third random access message (Msg3), etc.

[0191] In an embodiment of the present application, the physical layer channels or signals include one or more of a physical random access channel (PRACH), a physical uplink shared channel (PUSCH), a physical downlink shared channel (PDSCH), a physical uplink control channel (PUCCH), a physical downlink control channel (PDCCH), a channel state information reference signal (CSI-RS), a channel sounding reference signal (SRS), a phase tracking reference signal (PTRS), and a tracking reference signal (TRS).

[0192] In the embodiment of the present application, different terminal devices correspond to different random access message processing delays, where different terminal devices refer to different processing capabilities of the physical layer channels of the terminal devices or different processing capabilities of the physical layer signals of the terminal devices. The network device needs to schedule different subsequent random access message transmission resources for the terminal devices according to different random access message processing delays. For example, when the random access message processing delay of a terminal device with no relaxed processing capability is small and a resource with a large delay is scheduled for the terminal device, the terminal device needs to wait a certain time after completing the processing for the received random access message and then transmit the subsequent random access message through the resource of the network device scheduling. In addition, when the random access message processing delay of a terminal device with relaxed capability is large, when a resource with a small delay is scheduled for the terminal device, at the time when the message needs to be sent by scheduling the resource, the terminal device has not completed the processing for the random access message received before, resulting in wasting resources.

[0193] In the embodiment of the present application, after the network device determines the random access message processing delay of the relaxed terminal device, in one example, when the previously received random access message is the first random access message, the network device sequentially determines the time when the terminal device can transmit the third random access message and the time when the terminal device can transmit the fourth random access message feedback according to the random access message processing delay, thereby scheduling a reasonable time domain resource to ensure that the terminal device can achieve the transmission of the third random access message or the transmission of the fourth random access message feedback in the time domain resource of scheduling. Here, the terminal device can implicitly report the processing capability of the physical layer channel or the processing capability of the physical layer signal of the relaxed terminal device through the previously transmitted first random access message, which makes it easy for the network device to determine the random access message processing delay of the relaxed terminal device.

[0194] In another example, when the previously received random access message is the third random access message, the network device can determine the time when the terminal device can transmit the fourth random access message feedback according to the random access message processing delay, thereby scheduling a reasonable time domain resource, and ensuring that the terminal device can achieve the transmission of the fourth random access message feedback in the scheduled time domain resource. Here, the terminal device can implicitly report the processing capability of the physical layer channel or the processing capability of the physical layer signal of the relaxed terminal device through the previously transmitted third random access message, which makes it easy for the network device to determine the random access message processing delay of the relaxed terminal device.

[0195] In the embodiments of the present application, the serving cell can support the access of the terminal device with relaxed processing capability. If the serving cell supports the access of the terminal device with relaxed processing capability, the network device can use the method in each of the above embodiments to determine the random access message processing delay of the terminal device, and further schedule the transmission of the subsequent random access message of the terminal device in the serving cell, or the network device directly schedules the transmission of the subsequent random access message of the terminal device in the serving cell according to the relaxed random access message processing delay of the terminal device.

[0196] If the serving cell does not support access for a terminal device with relaxed processing capabilities, the network device may schedule transmission of a subsequent random access message of the terminal device in the serving cell based on the random access message processing delay of the terminal device without relaxed processing capabilities.

[0197] By implementing the embodiment of the present application, the network device schedules the transmission of subsequent random access messages of terminal devices in the serving cell where the network device is located based on the mitigated random access message processing delay of the terminal devices. By performing resource scheduling processing in this manner, all terminal devices accessing the serving cell can successfully transmit messages by scheduling resources, avoiding resource rescheduling when messages fail, avoiding resource waste, and improving resource utilization.

[0210] In one embodiment, the transceiver unit 1001 further sends configuration or instruction information to the terminal device, where the configuration or instruction information configures or indicates candidate resource groups corresponding to the processing capabilities of physical layer channels / signals of the at least two types of terminal devices.
