Description

Technical Field

[0001] The present application relates to the field of mobile communication technology, and in particular to a communication method and device based on configuration authorization configuration and heterofrequency measurement configuration. Background Art

[0002] With the continuous development of wireless communication systems, data transmission delay is continuously reduced and transmission capacity is increasing. Wireless communication systems are gradually infiltrating some services with strong real-time requirements and large data capacity requirements, such as video transmission, cloud gaming, and extended reality (XR). Among them, XR refers to a combination of real and virtual environments that can interact with humans and machines through computer technology and wearable devices. It is a general term for various forms such as augmented reality (AR) and virtual reality (VR).

[0003] Cloud gaming services and XR services generally have the characteristics of periodic transmission. Therefore, when transmitting downlink service data, semi-persistent scheduling (SPS) can usually be used, and when transmitting uplink service data, configured grant (CG) can usually be used. At present, when the SPS transmission timing and / or CG transmission timing conflicts with the measurement gap (MG), it may increase the delay of service transmission and affect service performance. Summary of the invention

[0004] The present application provides a communication method and apparatus based on configuration authorization configuration and heterodyne measurement configuration, which are used to reduce service transmission delay when an SPS transmission timing and / or a CG transmission timing conflicts with an MG.

[0005] In the first aspect, a communication method is provided. The method can be implemented by a first communication device. The first communication device can be a terminal device, or a component in the terminal device, for example, a terminal device. Among them, the components in the present application may include at least one of functional modules such as a chip, a chip system, a processor, a transceiver, a processing unit, or an interface unit. The method can also be implemented by a logical node, a logical module or software that can realize all or part of the functions of the terminal device. Taking the execution subject as an example, the method can be implemented by the following steps: the terminal receives first configuration information and second configuration information from an access network device, the first configuration information is used to configure a first CG transmission timing and a first time offset, and the second configuration information is used to configure a measurement timing, and the measurement timing is used for heterofrequency measurement; when the first CG transmission timing overlaps with the measurement timing in the time domain, the terminal sends uplink information to the access network device through the second CG transmission timing, wherein the time interval between the second CG transmission timing and the first CG transmission timing is equal to the first time offset.

[0006] Based on the method shown in the first aspect, the terminal and the access network device can transmit uplink data through the second CG transmission opportunity when the first CG transmission opportunity and the measurement opportunity overlap in time domain. The time interval between the second CG transmission opportunity and the first CG transmission opportunity can be the first time offset configured by the access network device. Therefore, when the first CG transmission opportunity and the measurement opportunity overlap in time domain, the uplink information can be transmitted in time through the second CG transmission opportunity, thereby reducing the service transmission delay.

[0007] In the second aspect, a communication method is provided. The method can be implemented by a second communication device. In the present application, the second communication device can be an access network device, or a component in the access network device, for example, referred to as an access network device. The access network device is, for example, a base station. The method can also be implemented by a logical node, a logical module or software that can implement all or part of the functions of the access network device. Taking the execution subject as an access network device as an example, the method can be implemented by the following steps: the access network device sends first configuration information and second configuration information to the terminal device, the first configuration information is used to configure the first configuration authorization CG transmission timing and the first time offset, the second configuration information is used to configure the measurement timing, and the measurement timing is used for heterofrequency measurement; when the first CG transmission timing overlaps with the measurement timing in the time domain, the uplink information from the terminal device is received through the second CG transmission timing, wherein the time interval between the second CG transmission timing and the first CG transmission timing is equal to the first time offset.

[0008] The beneficial effects of the method shown in the second aspect can refer to the beneficial effects of the first aspect.

[0009] In a possible implementation of the first aspect or the second aspect, the length of the first time offset is greater than or equal to the length of the measurement opportunity. Based on this implementation, it can be ensured that the time domain position of the second CG transmission opportunity is located after the time domain position of the measurement opportunity, thereby avoiding the second CG transmission opportunity from overlapping with the measurement opportunity.

[0010] In a possible implementation of the first aspect or the second aspect, the length of the first time offset is less than or equal to the length of the time interval between the end position of the CG cycle period in which the first CG transmission opportunity is located and the end position of the first CG transmission opportunity. Based on this implementation, it can be ensured that the second CG transmission opportunity and the first CG transmission opportunity are in the same CG cycle period, which can reduce the uplink delay.

[0011] In a possible implementation of the first aspect or the second aspect, the first CG transmission opportunity includes N1 CG transmission opportunities, where N1 is a positive integer greater than 1; wherein at least K1 CG transmission opportunities among the first CG transmission opportunities overlap with the measurement opportunity in the time domain.

[0012] Based on this implementation, K1 can be used as a threshold. When the number of CG transmission opportunities that overlap with the measurement opportunity among the N1 CG transmission opportunities included in the first CG transmission opportunity is at least K1, uplink information can be transmitted between the terminal and the access network device through the second CG transmission opportunity. Otherwise, uplink information can still be transmitted according to the N1-K1 CG transmission opportunities in the first CG transmission opportunity that do not overlap with the measurement opportunity. At this time, the delay caused by the measurement opportunity on service transmission is limited. Compared with sending uplink information using the second CG transmission opportunity, using the N1-K1 CG transmission opportunities to transmit uplink information can reduce transmission delay and reduce system complexity.

[0013] In a possible implementation of the first aspect or the second aspect, the first configuration information is also used to configure the ratio of the K1 or the K1 CG transmission opportunities to the N1 CG transmission opportunities. Based on this implementation, the access network device can configure the K1 threshold through the first configuration information, and the configuration method can be to directly configure K1 or to configure the ratio, such as configuring the value of K1 / N1. The " / " here represents a division operation.

[0014] In a possible implementation of the first aspect or the second aspect, the logical channel used to carry the uplink information is a high-priority logical channel. Based on this implementation, in the transmission process for logical channels with higher priorities, when the first CG transmission opportunity and the measurement opportunity overlap in the time domain, the uplink information can be sent through the second CG transmission opportunity, thereby reducing the service delay of the high-priority logical channel. The method of the present application may not be used in the transmission of low-priority logical channels to reduce complexity, and can give priority to the transmission performance of services with higher importance when resources are limited.

The first communication device can be a terminal device, or a component in the terminal device, for example, called a terminal device. The method can also be implemented by a logical node, a logical module or software that can implement all or part of the functions of the terminal device. Taking the execution subject as an example, the method can be implemented by the following steps: the terminal receives third configuration information and second configuration information from the access network device, the third configuration information is used to configure a third CG transmission opportunity, and the second configuration information is used to configure a measurement opportunity, and the measurement opportunity is used for heterofrequency measurement; when the third CG transmission opportunity overlaps with the measurement opportunity in the time domain, the terminal can send uplink information to the access network device through the fourth CG transmission opportunity, wherein the time interval between the fourth CG transmission opportunity and the third CG transmission opportunity is related to the length or end position of the measurement opportunity.

[0016] Based on the method shown in the third aspect, the terminal and the access network device can transmit uplink information through the fourth CG transmission opportunity when the third CG transmission opportunity overlaps with the measurement opportunity in the time domain. Among them, the time interval between the fourth CG transmission opportunity and the third CG transmission opportunity can be determined according to the length or end position of the measurement opportunity. Therefore, when the third CG transmission opportunity overlaps with the measurement opportunity in the time domain, the uplink information can be transmitted in time through the fourth CG transmission opportunity, thereby reducing the service transmission delay.

[0017] In a fourth aspect, a communication method is provided. The method may be implemented by a second communication device. In the present application, the second communication device may be an access network device, or a component in the access network device, such as an access network device. The method may also be implemented by a logical node, a logical module or software that can implement all or part of the functions of the access network device. Taking the execution subject as an access network device as an example, the method may be implemented by the following steps: the access network device sends third configuration information and second configuration information to the terminal device, the third configuration information is used to configure a third CG transmission opportunity, the second configuration information is used to configure a measurement opportunity, and the measurement opportunity is used for heterofrequency measurement; when the third CG transmission opportunity overlaps with the measurement opportunity in the time domain, the access network device receives uplink information from the terminal device through the fourth CG transmission opportunity, wherein the time interval between the fourth CG transmission opportunity and the third CG transmission opportunity is related to the length or end position of the measurement opportunity.

[0018] The beneficial effects of the method shown in the fourth aspect can refer to the beneficial effects of the third aspect.

[0019] In a possible implementation of the third aspect or the fourth aspect, the third CG transmission opportunity and the fourth CG transmission opportunity are located in the same CG cycle period. Based on this implementation, it can be ensured that the fourth CG transmission opportunity and the third CG transmission opportunity are located in the same CG cycle period, which can reduce the uplink delay.

[0020] In a possible implementation of the third aspect or the fourth aspect, the starting position of the fourth CG transmission opportunity is related to the time interval between the end position of the measurement opportunity and the starting position of the third CG transmission opportunity. Based on this implementation, the starting position of the fourth CG transmission opportunity can be determined according to the time interval between the end position of the measurement opportunity and the starting position of the third CG transmission opportunity, which can achieve reasonable determination of the fourth CG transmission opportunity and help reduce transmission delay.

[0021] In a possible implementation of the third aspect or the fourth aspect, the starting position of the fourth CG transmission opportunity is related to the ending position of the measurement opportunity. Based on this implementation, the starting position of the fourth CG transmission opportunity can be determined according to the ending position of the measurement opportunity, which can achieve reasonable determination of the fourth CG transmission opportunity and help reduce transmission delay.

[0022] In a possible implementation of the third aspect or the fourth aspect, the length of the time interval is greater than or equal to the length of the measurement opportunity. Based on this implementation, it is possible to ensure that the time domain position of the fourth CG transmission opportunity is located after the time domain position of the measurement opportunity, thereby avoiding the fourth CG transmission opportunity from overlapping with the measurement opportunity.

[0023] In a possible implementation of the third aspect or the fourth aspect, the length of the time interval is less than or equal to the length of the time interval between the end position of the CG cycle period in which the third CG transmission opportunity is located and the end position of the third CG transmission opportunity. Based on this implementation, it can be further ensured that the fourth CG transmission opportunity and the third CG transmission opportunity are in the same CG cycle period, which can reduce the uplink delay.

[0024] In a possible implementation of the third aspect or the fourth aspect, the third CG transmission opportunity includes N2 CG transmission opportunities, where N2 is a positive integer greater than 1; wherein at least K2 CG transmission opportunities among the third CG transmission opportunities overlap with the measurement opportunity in the time domain.

[0025] Based on this implementation, K2 can be used as a threshold. When the number of CG transmission opportunities that overlap with the measurement opportunity among the N2 CG transmission opportunities included in the third CG transmission opportunity is at least K2, uplink information can be transmitted between the terminal and the access network device through the fourth CG transmission opportunity. Otherwise, uplink information can still be transmitted according to the N2-K2 CG transmission opportunities in the third CG transmission opportunity that do not overlap with the measurement opportunity. At this time, the delay caused by the measurement opportunity on service transmission is limited. Compared with sending uplink information using the fourth CG transmission opportunity, using the N2-K2 CG transmission opportunities to transmit uplink information can reduce transmission delay and reduce system complexity.

[0026] In a possible implementation of the third aspect or the fourth aspect, the third configuration information is further used to configure the K2 or the ratio of the K2 CG transmission opportunities to the N2 CG transmission opportunities. Based on this implementation, the access network device can configure the K2 threshold through the third configuration information, and the configuration method can be to directly configure K2 or to configure the ratio, such as configuring the value of K2 / N2.

[0027] In a possible implementation of the third aspect or the fourth aspect, the logical channel used to carry the uplink information is a high-priority logical channel. Based on this implementation, in the transmission process for logical channels with higher priorities, when the third CG transmission opportunity and the measurement opportunity overlap in the time domain, the uplink information can be sent through the fourth CG transmission opportunity, thereby reducing the service delay of the high-priority logical channel. The method of the present application may not be used in the transmission of low-priority logical channels to reduce complexity, and can give priority to the transmission performance of services with higher importance when resources are limited.

[0028] In a fifth aspect, a communication method is provided. The method can be implemented by a first communication device. The first communication device can be a terminal device, or a component in the terminal device, for example, called a terminal device. The method can also be implemented by a logical node, a logical module or software that can implement all or part of the functions of the terminal device. Taking the execution subject as an example, the method can be implemented by the following steps: the terminal receives fourth configuration information and second configuration information from the access network device, the fourth configuration information is used to configure the first SPS transmission timing and the second time offset, the second configuration information is used to configure the measurement timing, and the measurement timing is used for heterofrequency measurement; when the first SPS transmission timing overlaps with the measurement timing in the time domain, the terminal can receive downlink information from the access network device through the second SPS transmission timing, wherein the time interval between the second SPS transmission timing and the first SPS transmission timing is equal to the second time offset.

[0029] Based on the method shown in the fifth aspect, the terminal and the access network device can transmit uplink data through the second SPS transmission opportunity when the first SPS transmission opportunity overlaps with the measurement opportunity in the time domain. Among them, the time interval between the second SPS transmission opportunity and the first SPS transmission opportunity can be the first time offset configured by the access network device. Therefore, when the first SPS transmission opportunity overlaps with the measurement opportunity in the time domain, the uplink information can be transmitted in time through the second SPS transmission opportunity, thereby reducing the service transmission delay.

[0030] In a sixth aspect, a communication method is provided. The method may be implemented by a second communication device. In the present application, the second communication device may be an access network device, or a component in the access network device, such as an access network device. The method may also be implemented by a logical node, a logical module or software that can implement all or part of the functions of the access network device. Taking the execution subject as an access network device as an example, the method may be implemented by the following steps: the access network device sends a fourth configuration information and a second configuration information to the terminal device, the fourth configuration information is used to configure a first semi-static scheduling SPS transmission timing and a second time offset, the second configuration information is used to configure a measurement timing, and the measurement timing is used for heterofrequency measurement; when the first SPS transmission timing overlaps with the measurement timing in the time domain, the access network device may send downlink information to the terminal device through the second SPS transmission timing, wherein the time interval between the second SPS transmission timing and the first SPS transmission timing is equal to the second time offset.

[0031] The beneficial effects of the method shown in the sixth aspect can refer to the beneficial effects of the fifth aspect.

[0032] In a possible implementation of the fifth aspect or the sixth aspect, the length of the second time offset is greater than or equal to the length of the measurement opportunity. Based on this implementation, it is possible to ensure that the time domain position of the second SPS transmission opportunity is located after the time domain position of the measurement opportunity, thereby avoiding the second SPS transmission opportunity from overlapping with the measurement opportunity.

[0033] In a possible implementation of the fifth aspect or the sixth aspect, the length of the second time offset is less than or equal to the length of the time interval between the end position of the SPS cycle period in which the first SPS transmission opportunity is located and the end position of the first SPS transmission opportunity. Based on this implementation, it can be ensured that the second SPS transmission opportunity and the first SPS transmission opportunity are in the same SPS cycle period, and the uplink delay can be reduced.

[0034] In a possible implementation of the fifth aspect or the sixth aspect, the first SPS transmission opportunity includes N3 SPS transmission opportunities, N3 is a positive integer greater than 1; wherein, at least K3 of the first SPS transmission opportunities overlap with the measurement opportunity in the time domain. Based on this implementation, K3 can be used as a threshold. When the number of SPS transmission opportunities overlapping with the measurement opportunity among the N3 SPS transmission opportunities included in the first SPS transmission opportunity is at least K3, downlink information can be transmitted between the terminal and the access network device through the second SPS transmission opportunity. Otherwise, downlink information can still be transmitted according to the N3-K3 SPS transmission opportunities in the first SPS transmission opportunity that do not overlap with the measurement opportunity. At this time, the delay caused by the measurement opportunity to the service transmission is limited. Compared with using the second SPS transmission opportunity to send downlink information, using the N3-K3 SPS transmission opportunities to transmit downlink information can reduce transmission delay and reduce system complexity.

[0035] In a possible implementation of the fifth aspect or the sixth aspect, the first configuration information is further used to configure the K3 or the ratio of the K3 SPS transmission opportunities to the N3 SPS transmission opportunities. Based on this implementation, the access network device can configure the K3 threshold through the first configuration information, and the configuration method can be to directly configure K3 or to configure the ratio, such as configuring the value of K3 / N3.

[0036] In a possible implementation of the fifth aspect or the sixth aspect, the logical channel used to carry the downlink information is a high-priority logical channel. Based on this implementation, in the transmission process for logical channels with higher priorities, when the first SPS transmission opportunity and the measurement opportunity overlap in the time domain, the downlink information can be sent through the second SPS transmission opportunity, thereby reducing the service delay of the high-priority logical channel. The method of the present application may not be used in the transmission of low-priority logical channels to reduce complexity, and can give priority to guaranteeing the transmission performance of services with higher importance when resources are limited.

Taking the execution subject as an example, the method can be implemented by the following steps: the terminal receives the fifth configuration information and the second configuration information from the access network device, the third configuration information is used to configure the third SPS transmission opportunity, the second configuration information is used to configure the measurement opportunity, and the measurement opportunity is used for heterofrequency measurement; when the third SPS transmission opportunity overlaps with the measurement opportunity in the time domain, the terminal can receive the downlink information from the access network device through the fourth SPS transmission opportunity, wherein the time interval between the fourth SPS transmission opportunity and the third SPS transmission opportunity is related to the length or end position of the measurement opportunity.

[0038] Based on the method shown in the seventh aspect, the terminal and the access network device can transmit downlink information through the fourth SPS transmission opportunity when the third SPS transmission opportunity overlaps with the measurement opportunity in the time domain. Among them, the time interval between the fourth SPS transmission opportunity and the third SPS transmission opportunity can be determined according to the length or end position of the measurement opportunity. Therefore, when the third SPS transmission opportunity overlaps with the measurement opportunity in the time domain, the downlink information can be transmitted in time through the fourth SPS transmission opportunity, thereby reducing the service transmission delay.

[0039] In an eighth aspect, a communication method is provided. The method may be implemented by a second communication device.

[0044] In a possible implementation of the seventh aspect or the eighth aspect, the length of the time interval is greater than or equal to the length of the measurement opportunity. Based on this implementation, it is possible to ensure that the time domain position of the fourth SPS transmission opportunity is located after the time domain position of the measurement opportunity, thereby avoiding the fourth SPS transmission opportunity from overlapping with the measurement opportunity.

[0045] In a possible implementation of the seventh aspect or the eighth aspect, the length of the time interval is less than or equal to the length of the time interval between the end position of the SPS cycle period in which the third SPS transmission opportunity is located and the end position of the third SPS transmission opportunity. Based on this implementation, it can be further ensured that the fourth SPS transmission opportunity and the third SPS transmission opportunity are in the same SPS cycle period, which can reduce the uplink delay.

[0048] In a possible implementation of the seventh aspect or the eighth aspect, the logical channel used to carry the downlink information is a high-priority logical channel. Based on this implementation, in the transmission process for logical channels with higher priorities, uplink information can be sent through the fourth CG transmission opportunity when the third CG transmission opportunity and the measurement opportunity overlap in the time domain, thereby reducing the service delay of the high-priority logical channel. The method of the present application may not be used in the transmission of low-priority logical channels to reduce complexity, and can give priority to the transmission performance of services with higher importance when resources are limited.

[0075] The embodiment of the present application provides a communication method and device based on configuration authorization configuration and inter-frequency measurement configuration. The method and device are based on the same inventive concept. Since the method and device solve the problem in a similar way, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0076] Figure 1FIG. 1 is a schematic diagram showing a possible, non-limiting system. Figure 1 As shown, the communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. The RAN 100 includes at least one RAN node (e.g. Figure 1 110a and 110b, collectively referred to as 110) and at least one terminal (such as Figure 1 120a-120j in the figure are collectively referred to as terminal 120). RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment ( Figure 1 The terminal 120 is connected to the RAN node 110 in a wireless manner. The RAN node 110 is connected to the core network 200 in a wireless or wired manner. The core network device in the core network 200 and the RAN node 110 in the RAN 100 may be different physical devices, or may be the same physical device that integrates the core network logical function and the radio access network logical function.

[0077] RAN 100 may be a cellular system related to the third generation partnership project (3GPP), for example, a 4G, 5G mobile communication system, or a future evolution system (for example, a 6G mobile communication system). RAN 100 may also be an open access network (open RAN, O-RAN or ORAN), a cloud radio access network (cloud radio access network, CRAN), or a wireless fidelity (wireless fidelity, WiFi) system. RAN 100 may also be a communication system that integrates two or more of the above systems.

[0078] The RAN node 110, which may also be sometimes referred to as an access network device, a RAN entity or an access node, constitutes a part of the communication system to help the terminal achieve wireless access. The multiple RAN nodes 110 in the communication system 10 may be nodes of the same type or nodes of different types. In some scenarios, the roles of the RAN node 110 and the terminal 120 are relative, for example, Figure 1 The network element 120i may be a helicopter or a drone, which may be configured as a mobile base station. For the terminals 120j that access the RAN 100 through the network element 120i, the network element 120i is a base station; but for the base station 110a, the network element 120i is a terminal. The RAN node 110 and the terminal 120 are sometimes referred to as communication devices, for example Figure 1The network elements 110a and 110b can be understood as communication devices with base station functions, and the network elements 120a-120j can be understood as communication devices with terminal functions.

[0079] In one possible scenario, the RAN node may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a new radio (NR), a next generation NodeB (gNB), or a next generation base station in a sixth generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. A RAN node may be a macro base station (e.g. Figure 1 110a in), micro base stations or indoor stations (such as Figure 1 110b in the description), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node may also be a server, a wearable device, a vehicle or an on-board device, etc. For example, the access network device in the vehicle to everything (V2X) technology may be a road side unit (RSU). All or part of the functions of the RAN node in the present application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform). The RAN node in the present application may also be a logical node, a logical module or software that can implement all or part of the functions of the RAN node.

[0080] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU) or a remote radio head (RRH).

[0081] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, CU, CU-CP, CU-UP, DU and RU are described as examples in this application. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0082] The terminal may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. The terminal can be widely used in various scenarios, for example, device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a robotic arm, a smart home device, etc. The embodiments of the present application do not limit the device form of the terminal. It is understood that for XR scenarios, the terminal may be a device such as a smart phone, a head mounted display (HMD) or smart glasses (such as VR glasses, AR glasses). For cloud gaming scenarios, the terminal may be a device such as a smart phone or a tablet computer.

[0083] In this application, "sending information to a terminal" can be understood as the destination of the information being the terminal. This can include sending information to the terminal directly or indirectly. "Receiving information from a terminal" can be understood as the source of the information being the terminal, which can include receiving information from the terminal directly or indirectly. The information may be processed as necessary between the source and destination of the information, such as format changes, but the destination can understand the valid information from the source. Similar expressions in this application can be understood similarly and will not be repeated here.

[0084] In the following, the method provided in the present application is introduced by taking the terminal and the access network device as the execution subject as an example. Among them, the terminal may include the aforementioned terminal 120. The access network device may include the aforementioned RAN node 110. It can be understood that the present application does not limit the execution subject of the method. For example, the method executed by the access network device in the present application may also be executed by a module of the access network device (such as a chip, a chip system, or a processor), and may also be implemented by a logical node, a logical module or software that can implement all or part of the access network device. The method executed by the terminal in the present application may also be executed by a module of the terminal (such as a chip, a chip system, or a processor), and may also be implemented by a logical node, a logical module or software that can implement all or part of the terminal functions.

[0085] The current business data of cloud games and XR services often has the characteristics of periodic transmission. Taking the downlink business data as an example, a video with a frame rate of 60 frames per second (FPS) arrives at a frame every 16.67 milliseconds (ms) under ideal conditions. The 3GPP standard requires XR video to have a transmission reliability of 99%. In addition, the uplink XR video air interface delay requirement is usually 30ms, and the downlink XR video air interface delay requirement is usually 10ms.

[0086] Based on the periodic characteristics of business data of cloud games and XR services, the access network equipment can configure the terminal to use CG to transmit uplink data of cloud games and / or XR services.

[0087] Among them, CG means that in the process of uplink transmission, the uplink scheduling resources only need to be allocated or specified once through radio resource control (RRC) signaling or physical downlink control channel (PDCCH), and then the same time-frequency resources can be periodically reused for uplink transmission. CG includes two types, namely type 1 CG and type 2 CG. Among them, type 1 CG refers to the configuration of relevant parameters of CG transmission through RRC signaling, such as configured scheduling radio network temporary identifier (CS-RNTI), CG period (periodicity), CG time domain resources, CG frequency domain resources, etc. In addition, in type 1 CG, the access network device can also activate the corresponding CG period through RRC signaling; in type 2 CG, the relevant parameters of CG transmission, such as CS-RNTI or CG period and other parameters, are configured through RRC signaling, and the corresponding CG period is activated through PDCCH and the allocated CG transmission timing and CG frequency domain resources are indicated. It can be understood that the CG period in this application refers to a time period with a length of CG period.

[0088] It is understandable that one or more CG transmission opportunities may be included in a CG cycle period. In the present application, the CG transmission opportunity is an uplink resource used to transmit uplink service data or PUSCH. The terminal can send uplink data to the access network device via PUSCH at the CG transmission opportunity. The CG transmission opportunity can also be replaced by other possible descriptions, such as CG resources, CG PUSCH, PUSCH resources, PUSCH opportunities, PUSCH opportunities, CG uplink resources, CG PUSCH resources, CG PUSCH transmission resources or transmission opportunities.

[0089] The current protocol stipulates that the CG period is an integer multiple of 2 symbol lengths, 7 symbol lengths, or 14 symbol lengths supported by NR. For example, when the subcarrier spacing is 30 kHz, the time slot length is 0.5 ms, and a time slot includes 14 symbols. The CG period length supported by the protocol is 2 symbols, 7 symbols, or (1 to 1280)*14 symbols, that is, the minimum period length supported by the protocol is 0.5 / 7ms, and the maximum period is 640ms.

[0090] Exemplarily, the CG scheduling process of type 1 is:

[0091] 1. The access network equipment configures the relevant parameters of the CG cycle period through high-level signaling, including CS-RNTI, CG cycle, CG time domain resources and frequency domain resources, etc. In addition, the access network equipment base station activates the corresponding CG cycle period through RRC signaling.

[0092] 2. The medium access control (MAC) entity of the terminal determines the time slot in which the CG period is periodically effective according to the CG configuration. Exemplarily, the position of the time slot may satisfy the following formula:

[0093] [(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)+(slot number in the frame×numberOfSymbolsPerSlot)+symbol number in the slot]=(timeReferenceSFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+timeDomainOffset×numberOfSymbolsPerSlot+S+N×periodicity)modulo(1024×numberOfSlotsPerFrame×numberOfSymbolsPerSlot);

[0094] Among them, SFN represents the wireless system frame number, numberOfSlotsPerFrame represents the number of time slots contained in the wireless system frame, numberOfSymbolsPerSlot represents the number of symbols contained in the time slot, slot number in the frame represents the number of time slots in the wireless system frame, symbol number in the slot represents the number of symbols in the time slot, refers to the starting symbol of the CG cycle period in the time slot, timeReferenceSFN is used to indicate the offset SFN of the CG transmission opportunity in the time domain, timeDomainOffset can be used to indicate the offset of the starting position of the CG cycle period from timeReferenceSFN, S refers to the time domain parameter configured in the high-level signaling, represents the current symbol (current_symbol), N represents the Nth CG cycle period, periodicity represents the CG period, and modulo() represents the modulo operation.

[0095] The CG scheduling process of type 2 is:

[0096] 1. The access network equipment configures relevant parameters of the CG cycle period through high-level signaling, including parameters such as CS-RNTI and CG cycle, which may include multiple groups of CG cycle period parameters. For example, multiple groups of CG cycle period parameters may correspond to different CG cycles.

[0097] 2. For uplink data (such as PUSCH) transmission, the access network equipment indicates the specific activated CG cycle period (for example, the period of the activated CG cycle period) through PDCCH (such as downlink control information (DCI) carried by PDCCH). In addition, the CG time domain resources and CG frequency domain resources specifically allocated for CG transmission can also be indicated through the resource allocation domain.

[0098] 3. The MAC entity determines the time domain symbol that periodically takes effect during the CG period according to the configuration of the CG. For example, the position of the time slot can satisfy the following formula:

[0099] [(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)+(slot number in the frame×numberOfSymbolsPerSlot)+symbol number in the slot]=[(SFNstarttime×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+slotstart time×numberOfSymbolsPerSlot+symbolstart time)+N×periodicity]modulo(1024×numberOfSlotsPerFrame×numberOfSymbolsPerSlot);

[0100] Among them, SFNstart time refers to the radio frame number at which PUSCH starts to send, slotstart time refers to the time slot number at which PUSCH starts to send, and symbolstart time refers to the symbol at which PUSCH starts to send. For other parameters, please refer to the description in Type 1CG configuration.

[0101] For type 1 CG or type 2 CG, if the corresponding CG cycle period needs to be released, the base station can indicate the release of the corresponding CG cycle period through PDCCH (such as DCI carried on PDCCH).

[0102] In addition, the access network device can configure the terminal to use SPS to transmit downlink data of cloud games and / or XR services.

[0103] Among them, SPS means that in the process of downlink transmission, the downlink scheduling resources only need to be allocated or specified once through PDCCH, and then the same time-frequency resources can be reused periodically, which can effectively reduce the overhead of PDCCH. The protocol stipulates that the relevant parameters of the SPS period are configured through RRC signaling, such as CS-RNTI and SPS period. The access network equipment can also indicate the SPS transmission timing and SPS frequency domain resources through PDCCH. It can be understood that the SPS period in this application refers to a time period with a length of SPS period.

[0104] It is understandable that one or more SPS transmission opportunities may be included in an SPS cycle period. In the present application, the SPS transmission opportunity is an uplink resource for transmitting downlink service data or PDSCH. The access network device can send downlink data to the terminal via PDSCH during the SPS transmission opportunity. The SPS transmission opportunity can also be replaced by other possible descriptions, such as SPS resources, SPS PDSCH, PDSCH resources, PDSCH opportunities, PDSCH opportunities, SPS downlink resources, SPS PDSCH resources, SPS PDSCH transmission resources or transmission opportunities.

[0105] The SPS period specified in the existing protocol is an integer multiple of the time slot length supported by NR. For example, when the subcarrier spacing is 30KHz and the time slot length is 0.5ms, the SPS period supported by the protocol is (1~1280)*0.5ms, that is, the minimum period supported by the protocol is 0.5ms and the maximum period is 640ms.

[0106] Exemplarily, the basic process of SPS scheduling is:

[0107] 1. The access network device configures the relevant parameters of the SPS period through RRC signaling, such as CS-RNTI or SPS period.

[0108] 2. When transmitting downlink data through the physical downlink shared channel (PDSCH), the access network device indicates the specific activated SPS cycle period (such as the period of the activated SPS cycle period) through the PDCCH (such as the downlink control information (DCI) carried by the PDCCH), and indicates the frequency domain resources specifically allocated for SPS transmission through the resource allocation field.

[0109] 3. The MAC entity determines the time slot during which the SPS period is periodically effective according to the SPS configuration. For example, the position of the time slot may satisfy the following formula:

[0110] (numberOfSlotsPerFrame×SFN+slot number in the frame)=[(numberOfSlotsPerFrame×SFNstart time+slotstart time)+N×periodicity×numberOfSlotsPerFrame / 10]modulo(1024×numberOfSlotsPerFrame);

[0111] Among them, SFN represents the wireless system frame number, numberOfSlotsPerFrame represents the number of time slots contained in the wireless system frame, slot number in the frame represents the number of time slots in the wireless system frame, N represents the Nth SPS cycle period, periodicity represents the period of the SPS cycle period, SFNstart time refers to the wireless frame number at the start of PDSCH transmission, and slotstart time refers to the time slot number at the start of PDSCH transmission. The meaning of other parameters can be found in the introduction of CG configuration and will not be repeated here.

[0112] 4. If the corresponding SPS cycle period needs to be released, the access network device may indicate the release of the corresponding resources through the PDCCH (such as the DCI carried on the PDCCH).

[0113] It is understood that the timing or transmission timing in the present application may refer to a time domain unit for transmitting information. The timing may also be referred to as a time unit. In the embodiments of the present application, there is no limitation on the unit or granularity of the timing. For example, the unit or granularity of the timing may be: a radio frame, a subframe, a slot, a mini-slot, or a time domain symbol, etc.

[0114] In one design, a wireless frame may include one or more subframes, a subframe may include one or more subframes, a subframe may include one or more time slots, a time slot may include one or more micro-time slots, a time slot or micro-time slot may include one or more time domain symbols, etc. The time domain symbol may be simply referred to as a symbol. The time domain symbol may be an orthogonal frequency division multiplexing (OFDM) symbol, or an orthogonal frequency division multiplexing (DFT-s-OFDM) symbol based on discrete Fourier transform spread, etc. A micro-time slot, also known as a mini-time slot, may be a smaller unit than a time slot. For example, a time slot may include 14 or 12 time domain symbols, and a micro-time slot may include 2, 4 or 7 time domain symbols.

[0115] Different time slot lengths may be used for different sub-carrier spacings (SCS). For example, when the sub-carrier spacing is 15 kHz, a time slot is 1 ms; when the sub-carrier spacing is 30 kHz, a time slot is 0.5 ms.

[0116] Taking a subcarrier spacing of 15kHz as an example, one radio frame may last for 10ms, one radio frame includes 10 subframes, one subframe may last for 1ms, one subframe may include one time slot, one time slot lasts for 1ms, and one time slot may include 14 time domain symbols. Furthermore, a micro time slot may include 4, 2 or 7 time domain symbols, etc.

[0117] In a mobile cellular network, when a terminal moves from one cell (or access network equipment coverage) to another, it needs to switch between cells. Before switching, the terminal needs to measure the signals of the neighboring cells to determine when to switch cells. 3GPP proposes to reserve a portion of measurement opportunities (i.e., MGs), during which the terminal cannot send or receive any data, and tunes the receiver to the target cell frequency for measurement. At the end of the measurement opportunity, the terminal switches the receiver to the current cell to resume sending and receiving.

[0118] The MG parameters configured by the access network device to the terminal may include:

[0119] (1) Gap offset: used to specify the starting subframe at the beginning of the gap. It ranges from 0 to mgrp-1 relative to the starting position of the MG period. mgrp is the value of the measurement gap repetition period (MGRP). The MG period can be a time period of length mgrp.

[0120] (2) MGRP: used for MG period, that is, the repetition period of measurement opportunity. Its value can be 20ms, 40ms, 80ms or 160ms. For example, when its value is 40ms, it means that MG repeats every 40ms.

[0121] (3) MG length (measurement gap length, MGL): used to specify the duration of a measurement opportunity in milliseconds. Its value can be 1.5, 3, 3.5, 4, 5.5 or 6.

[0122] For example, common MG parameter configuration methods include: parameter combination (MGL, MGRP) = (6ms, 40ms), (6ms, 80ms) is a mandatory parameter, that is, the terminal must support this parameter configuration. Other parameter combinations can be optional parameters for the terminal, or conditionally optional parameters. For example, parameter combinations such as (MGL, MGRP) = (1.5ms, 80ms) are optional transmission parameters for the terminal.

[0123] At present, when the SPS transmission timing and / or the CG transmission timing conflicts with the MG, the terminal cannot transmit according to the SPS transmission timing and / or the CG transmission timing, but needs to measure at the measurement timing, which may increase the delay of service transmission and affect service performance. In the present application, the conflict between the SPS transmission timing and / or the CG transmission timing and the MG can be reflected in that the SPS transmission timing and / or the CG transmission timing overlaps with the measurement timing in the time domain. In the present application, the overlap of two timings in the time domain may refer to partial overlap or complete overlap of the two timings in the time domain.

[0124] Take the CG transmission timing as an example, Figure 2 As shown in the figure, when the MG length is configured to 6ms and the MG period is configured to 40ms, for uplink service data with a frame rate of 60 frames per second, some CG transmission opportunities that overlap with the MG measurement opportunities cannot be used to transmit video frames, resulting in reduced communication capacity and increased transmission delay. Figure 2 The cases where one CG cycle period includes one CG transmission opportunity and the case where one CG cycle period includes five CG transmission opportunities are respectively shown.

[0125] In view of this, an embodiment of the present application provides a communication method for reducing service transmission delay when the SPS transmission timing and / or the CG transmission timing conflicts with the MG.

[0126] Figure 3 A flow chart corresponding to a communication method provided in an embodiment of the present application.

[0127] like Figure 3 As shown, the method comprises the following steps:

[0128] S101: The access network device sends first configuration information and second configuration information to a terminal. Correspondingly, the terminal receives the first configuration information and the second configuration information.

[0129] The first configuration information may be used to configure a first CG transmission opportunity and a first time offset. The first CG transmission opportunity may include one or more CG transmission opportunities within a CG cycle period.

[0130] The second configuration information may be used to configure a measurement opportunity, and the measurement opportunity is used for inter-frequency measurement.

[0131] S102: When the first CG transmission opportunity overlaps with the measurement opportunity in the time domain, the terminal sends uplink information to the access network device through the second CG transmission opportunity. The time interval between the second CG transmission opportunity and the first CG transmission opportunity is equal to the first time offset. Therefore, the time domain position of the second CG transmission opportunity can be determined based on the time domain position of the first CG and the first time offset, see the introduction below.

[0132] Among them, the uplink information may include uplink data of cloud gaming services and / or uplink data of XR services.

[0133] Correspondingly, when the first CG transmission opportunity and the measurement opportunity overlap in the time domain, the access network device receives the uplink information sent by the terminal through the second CG transmission opportunity.

[0134] It can be seen that based on Figure 3 As shown in the process, in a communication method provided by the present application, the terminal and the access network device can transmit uplink information through the second CG transmission opportunity when the first CG transmission opportunity and the measurement opportunity overlap in time domain. The time interval between the second CG transmission opportunity and the first CG transmission opportunity can be the first time offset configured by the access network device. Therefore, when the first CG transmission opportunity and the measurement opportunity overlap in time domain, the uplink information can be transmitted in time through the second CG transmission opportunity, thereby reducing the service transmission delay.

[0135] The first configuration information involved in S101 is described below.

[0136] In a possible embodiment, the first configuration information may be used to configure the CG. For example, the first configuration information may at least be used to configure parameters such as the CG period, CG time domain resources, etc. The CG configured by the first configuration information may be a type 1 CG or a type 2 CG, which is not specifically limited in this application.

[0137] Specifically, the first configuration information may include a time domain resource configuration for indicating the first CG transmission opportunity. For example, the first configuration information may include a period field and a time domain allocation status field in the ConfiguredGrantConfig domain. For example, the time domain allocation status parameter may include a time domain resource allocation (timeDomainAllocation) field and a time domain offset (timeDomainOffset) field.

[0138] Among them, the time domain resource allocation field can be used to indicate the combination of the starting symbol length and the PUSCH mapping type. For example, the value of the time domain resource allocation field can be used to indicate a row in the resource allocation table, and the row information can be used to determine the time domain position of the first CG transmission opportunity. Exemplarily, any row in the resource allocation table contains a set of CG cycle period indication information, such as the time slot offset of the CG transmission opportunity, the starting symbol of the CG transmission opportunity relative to the start of the time slot (ie S), and the number of consecutive symbols L contained in the CG transmission opportunity (ie the length of the CG transmission opportunity). The time domain offset field can be used to indicate the offset of the time-frequency resources relative to the system frame number (SFN).

[0139] It is understandable that the terminal can determine the time domain position of the first CG transmission opportunity based on the time domain resource allocation field and the time domain offset field, and the determination method does not belong to the limited content in this application. This application also does not limit the first configuration information to configure the CG transmission opportunity in other ways.

[0140] Alternatively, when the CG cycle period configured by the first configuration information includes multiple CG transmission opportunities, the first configuration information may also include the time intervals between the multiple CG transmission opportunities. For example, when multiple CG transmission opportunities are distributed at equal time intervals, the first configuration information may include a parameter for indicating the time intervals between the multiple CG transmission opportunities.

[0141] In addition, the first configuration information may also include a configuration of a first time offset, which is used to indicate the time interval between the second CG transmission opportunity and the first CG transmission opportunity. Therefore, the starting position of the second CG transmission opportunity can be determined by the first time offset based on the starting position of the first CG transmission opportunity. For example, the moment value of the time domain starting position of the second CG transmission opportunity is the sum of the moment value of the time domain starting position of the first CG transmission opportunity and the value of the first time offset. In S102, the second CG transmission opportunity can be used for the terminal to send uplink information.

[0142] Optionally, the time domain length of the second CG transmission opportunity may be the same as or different from the time domain length of the first CG transmission opportunity, which is not specifically limited in this application. Among them, if the time domain length of the second CG transmission opportunity is different from the time domain length of the first CG transmission opportunity, the first configuration information may also include the configuration of the time domain length of the second CG transmission opportunity; or, the time domain length of the second CG transmission opportunity may adopt a default configuration, which may be determined in a predefined or preconfigured manner. In this application, the predefined method may refer to a configuration implemented based on the local configuration information of the device, and the local configuration information may include factory configuration information of the device or configuration information based on a protocol or standard. The preconfigured method may refer to the access network device configuring the terminal through signaling or information such as RRC signaling, MAC CE or DCI.

[0143] It can be understood that no matter whether the first CG transmission opportunity includes one or more CG transmission opportunities, the second CG transmission opportunity may include one CG transmission opportunity or multiple CG transmission opportunities. If the second CG transmission opportunity includes multiple CG transmission opportunities, the first time offset may be used to indicate the time interval between the first CG transmission opportunity in the second CG transmission opportunity and the first CG transmission opportunity.

[0144] It can also be understood that the number of CG transmission opportunities included in the second CG transmission opportunity may be the same as or different from the number of CG transmission opportunities included in the first CG transmission opportunity, and this application does not specifically limit it. For example, the first CG transmission opportunity includes M CG transmission opportunities in a CG cycle period, M is a positive integer, and when the time interval between the end position of the first CG transmission opportunity and the end position of the CG cycle period is large, the second CG transmission opportunity may include no less than M CG transmission opportunities. For another example, the first CG transmission opportunity includes M CG transmission opportunities in a CG cycle period, M is a positive integer, and when the time interval between the end position of the first CG transmission opportunity and the end position of the CG cycle period is small, the second CG transmission opportunity may include no more than M CG transmission opportunities.

[0145] In addition, the intervals between the multiple CG transmission opportunities included in the second CG transmission opportunity may be the same as or different from the intervals between the multiple CG transmission opportunities included in the first CG transmission opportunity.

[0146] like Figure 4 As shown in the scenario numbered (a), for a CG cycle period that includes only one CG transmission opportunity, the CG transmission opportunity is the first CG transmission opportunity, and the first time offset can be the time interval between the second CG transmission opportunity and the first CG transmission opportunity. Figure 4 As shown in the scenario numbered (b), for the case where a CG cycle period includes multiple CG transmission opportunities, the multiple CG transmission opportunities are the first CG transmission opportunity. At this time, the first time offset can be the time interval between the second CG transmission opportunity and the first CG transmission opportunity among the multiple CG transmission opportunities included in the first CG transmission opportunity.

[0147] Optionally, the first configuration information includes a configuration authorization-measurement interval-offset (CG-MG-offset) field, whose value is the first time offset, that is, the CG-MG-offset field can be used to configure the first time offset. It is not excluded that the first configuration information indicates the first time offset through other fields or reuses existing fields.

[0148] The numerical range of the first time offset is introduced below.

[0149] The value of the first time offset represents the time domain length of the first time offset. Therefore, the value range of the first time offset is equivalent to the length range of the first time offset.

[0150] In a possible embodiment, the length of the first time offset is greater than or equal to the length of the measurement opportunity, or the value of the first time offset may be not less than the length of the measurement opportunity. The length of the measurement opportunity is the MG length, and its value may be indicated by the MGL field. The advantage of adopting this design is that by reasonably setting the value of the first time offset, the second CG transmission opportunity is located after the measurement opportunity, so that the terminal can send uplink information after the measurement opportunity, thereby avoiding the inability to send uplink information due to the overlap of the measurement opportunity and the first CG transmission opportunity.

[0151] In a possible embodiment, the length of the first time offset is less than or equal to the length of the time interval between the end position of the CG cycle period where the first CG transmission opportunity is located and the end position of the first CG transmission opportunity. In other words, the value of the first time offset is less than or equal to the difference between the moment of the end position of the CG cycle period where the first CG transmission opportunity is located and the moment of the end position of the first CG transmission opportunity. The advantage of adopting this design is that by reasonably setting the value of the first time offset, the second CG transmission opportunity and the first CG transmission opportunity are located in the same CG cycle period, so that the terminal can send uplink information in time and reduce transmission delay.

[0152] It can be understood that the access network device can determine the value of the first time offset according to the numerical range of the first time offset.

[0153] In addition, the first configuration information may also include other parameters included in the type 1 CG and / or type 2 CG. Please refer to the description of the CG parameters in this application, or refer to the description in the relevant communication standards or protocols.

[0154] Optionally, the first configuration information may be (or be included in) high-level configuration signaling, such as an RRC message, or a MAC control element (CE). For example, the first configuration information may include a ConfiguredGrantConfig field for configuring the CG. In addition, it is not excluded that the first configuration information includes information in non-high-level configurations such as DCI, such as a resource allocation field, etc.

[0155] The second configuration information is described below.

[0156] In the present application, the second configuration information may be used to configure a measurement opportunity, and the measurement opportunity may be a MG. The measurement opportunity may be used for inter-frequency measurement.

[0157] The second configuration information may be configuration information of MG parameters, which may be used to determine the time domain position of the measurement opportunity in the present application. For example, the second configuration information may be used to configure one or more parameters of the MG interval offset, MGRP and MG length.

[0158] Optionally, the second configuration information may be (or included in) a higher-layer configuration signaling, such as an RRC message, or a MACCE, etc. For example, the second configuration information may include a measurement gap configuration (MeasGapConfig) field.

[0159] The following introduces the method in S102 in which the terminal and / or access network device determines whether there is a time domain overlap between the first CG transmission timing and the measurement timing.

[0160] In one implementation of S102, the terminal and / or access network device can determine whether there is a time domain overlap between the first CG transmission opportunity and the measurement opportunity based on the time domain position of the first CG transmission opportunity and the time domain position of the measurement opportunity. For example, the terminal and / or access network device can determine the time domain position of the first CG transmission opportunity based on the first configuration information, and determine the time domain position of the measurement opportunity based on the second configuration information, and then determine whether there is an overlap between the time domain position of the first CG transmission opportunity and the time domain position of the measurement opportunity.

[0161] In another implementation of S102, the terminal and / or access network device can also determine whether there is a time domain overlap between the first CG transmission opportunity and the measurement opportunity based on the first configuration information and the second configuration information, without first determining the time domain position of the first CG transmission opportunity and the time domain position of the measurement opportunity. For example, the terminal and / or access network device can determine whether the time domain position of the first CG transmission opportunity within a certain CG cycle period overlaps with the time domain position of the measurement opportunity based on the period, time domain resource allocation field, time domain offset terminal indicated by the first configuration information, and the interval offset, MGRP and MG length of the MG indicated by the second configuration information, by formula or table lookup.

[0162] It can be understood that in S102, when the first CG transmission opportunity overlaps with the measurement opportunity in the time domain, the terminal and / or the access network device can determine the time domain position of the second CG transmission opportunity based on the time domain position of the first CG transmission opportunity and the first time offset, so as to transmit uplink information through the second CG transmission opportunity. For example, the terminal and / or the access network device can use the sum of the time value of the time domain starting position of the first CG transmission opportunity and the value of the first time offset as the time value of the time domain starting position of the second CG transmission opportunity.

[0163] In an optional embodiment of S102, if the first CG transmission opportunity includes N1 CG transmission opportunities, and N1 is a positive integer greater than 1, the terminal can send uplink information to the access network device through the second CG transmission opportunity when at least K1 (or, more than K1) of the N1 CG transmission opportunities overlap with the measurement opportunity in the time domain. Correspondingly, the access network device can receive the uplink information sent by the terminal through the second CG transmission opportunity when at least K1 of the N1 CG transmission opportunities overlap with the measurement opportunity in the time domain. In this embodiment, K1 can be used as a threshold condition to trigger the execution of S102, that is, uplink information will be sent through the second CG transmission opportunity only when no less than K1 transmission opportunities overlap with the measurement opportunity in the time domain.

[0164] For example Figure 4As shown in (b), a CG cycle period includes N1=5 CG transmission opportunities. When K1=3 is configured, it is necessary to use the second CG transmission opportunity to send uplink information when at least 3 CG transmission opportunities overlap with the measurement opportunity. In the case that 1 or 2 CG transmission opportunities among N1=5 CG transmission opportunities overlap with the measurement opportunity, it is not necessary to use the second CG transmission opportunity to send uplink information. At this time, the terminal and the access network device still use the CG transmission opportunities among N1=5 CG transmission opportunities that do not overlap with the measurement opportunity to transmit uplink information.

[0165] The advantage of this design is that if N1 CG transmission opportunities are configured in a CG cycle period, and P1 of the CG transmission opportunities overlap with the measurement opportunity, if P1 is less than K1, the delay caused by the measurement opportunity on the service transmission is limited, because there are still at least K1-P1 CG transmission opportunities available for service transmission. At this time, the transmission scheme of S102 can be omitted to reduce system complexity. When at least K1 of the N1 CG transmission opportunities overlap with the measurement opportunity, and the remaining N1-K1 transmission opportunities cannot meet the service transmission requirements, the scheme shown in S102 can be used to send uplink information.

[0166] Optionally, in this embodiment, the first configuration information can also be used to configure K1, for example, to configure the value of K1. Alternatively, the first configuration information can also be used to configure the ratio of K1 CG transmission opportunities to N1 CG transmission opportunities, and the ratio can be expressed as K1 / N1, where " / " represents a division operation. In addition, it is not excluded that the access network device uses information or messages such as RRC signaling, MAC CE or DCI other than the first configuration information to configure K1 or the above ratio. K1 or the above ratio can also be pre-configured in the terminal and / or access network device through a protocol or factory configuration.

[0167] In another embodiment of S102, the uplink information sent by the terminal device to the access network device can be carried on a high-priority logical channel. In other words, if the uplink information is carried on a low-priority logical channel, the method shown in the present application can be ignored for sending. Therefore, in the transmission process for logical channels with higher priorities, when the first CG transmission opportunity and the measurement opportunity overlap in the time domain, the uplink information can be sent through the second CG transmission opportunity, thereby reducing the service delay of the high-priority logical channel. The method of the present application can be omitted in the transmission of low-priority logical channels to reduce complexity, and can give priority to the transmission performance of services with higher importance when resources are limited.

[0168] In the present application, the priority of a logical channel can be determined according to the value of the priority field in the logical channel configuration (LogicalChannelConfig) domain. Among them, the logical channel with a smaller value of the priority field has a higher priority. The logical channel configuration domain corresponding to the logical channel of the uplink information can be carried in the RRC signaling, MAC CE or DCI sent by the access network device to the terminal.

[0169] Exemplarily, a high-priority logical channel may refer to a logical channel whose priority field value is less than or equal to the priority field threshold. In other words, the priority field value of the high-priority logical channel is less than or equal to the priority field value of at least one other uplink logical channel of the terminal's uplink information.

[0170] Figure 5 A flow chart corresponding to a communication method provided in an embodiment of the present application. Figure 5 The method shown is Figure 3 The method shown differs in that in Figure 5 In the method shown, the access network device does not need to configure the first time offset. In addition, when the CG transmission timing overlaps with the measurement timing, the terminal and / or the access network device can determine the CG transmission timing used for uplink transmission based on the length or end position of the measurement timing.

[0171] like Figure 5 As shown, the method may include the following steps:

[0172] S201: The access network device sends third configuration information and second configuration information to the terminal. Correspondingly, the terminal receives the third configuration information and the second configuration information.

[0173] The third configuration information may be used to configure a third CG transmission opportunity. The third CG transmission opportunity may include one or more CG transmission opportunities within a CG cycle period. The second configuration information may be used to configure a measurement opportunity. The second configuration information and the measurement opportunity may refer to the description in S101 and will not be repeated here.

[0174] The third configuration information is described below.

[0175] In a possible embodiment, the third configuration information may be used to configure the CG. For example, the third configuration information may at least be used to configure parameters such as the CG period, CG time domain resources, etc. The CG configured by the third configuration information may be a type 1 CG or a type 2 CG, which is not specifically limited in this application.

[0176] Specifically, the third configuration information may include a time domain resource configuration for indicating a third CG transmission opportunity. For details, please refer to the description of configuring the first CG transmission opportunity with the first configuration information in S101 in this application.

[0177] Alternatively, when the CG cycle period configured by the third configuration information includes multiple CG transmission opportunities, the first configuration information may also include the time intervals between the multiple CG transmission opportunities. For example, when multiple CG transmission opportunities are distributed at equal time intervals, the third configuration information may include a parameter for indicating the time intervals between the multiple CG transmission opportunities.

[0178] It can be understood that the third configuration information may also include other parameters included in type 1 CG and / or type 2 CG. Please refer to the description of CG parameters in this application, or refer to the description in the relevant communication standards or protocols.

[0179] Optionally, the third configuration information may be (or be included in) high-level configuration signaling, such as an RRC message, or a MACCE, etc. For example, the third configuration information may include a ConfiguredGrantConfig field for configuring the CG. In addition, it is not excluded that the third configuration information includes information in non-high-level configurations such as DCI, such as a resource allocation field, etc.

[0180] S202: When the third CG transmission opportunity overlaps with the measurement opportunity in the time domain, the terminal sends uplink information to the access network device through the fourth CG transmission opportunity. Correspondingly, when the third CG transmission opportunity overlaps with the measurement opportunity in the time domain, the access network device receives the uplink information sent by the terminal through the fourth CG transmission opportunity.

[0181] In S202, the time interval between the fourth CG transmission opportunity and the third CG transmission opportunity is related to the length or end position of the measurement opportunity.

[0182] It can be understood that the method in which the terminal and / or access network device in S202 determines whether there is a time domain overlap between the third CG transmission timing and the measurement timing can refer to the introduction of the method in S102 for determining whether there is a time domain overlap between the first CG transmission timing and the measurement timing, and the repeated parts will not be repeated.

[0183] In S202, the end position of the measurement opportunity is related to the length of the measurement opportunity, or it can be said that the end position of the measurement opportunity can be determined according to the length of the measurement opportunity. For example, when the access network device configures the interval offset, MGRP and MG length of the MG, the time domain position of the measurement opportunity within the MG cycle period can be determined according to the interval offset, MGRP and MG length of the MG.

[0184] As a possible embodiment, the fourth CG transmission opportunity may be the first uplink time slot after the measurement opportunity, and thus the time interval between the fourth CG transmission opportunity and the third CG transmission opportunity may be determined according to the end position of the measurement opportunity.

[0185] In this embodiment, the terminal and / or access network device can determine the uplink time slot where the fourth CG transmission opportunity is located based on the end position of the measurement opportunity that coincides with the third CG transmission opportunity.

[0186] As another possible embodiment, the time interval between the fourth CG transmission opportunity and the third CG transmission opportunity may be equal to the time difference between the end position of the measurement opportunity and the start position of the third CG transmission opportunity. That is, the time interval between the fourth CG transmission opportunity and the third CG transmission opportunity may satisfy the following formula:

[0187] The time interval between the fourth CG transmission opportunity and the third CG transmission opportunity = the time value of the end position of the measurement opportunity - the time value of the start position of the third CG transmission opportunity.

[0188] In this embodiment, the terminal and / or access network device can determine the time domain position of the fourth CG transmission opportunity based on the time domain position of the third CG transmission opportunity and the time difference between the end position of the measurement opportunity and the start position of the third CG transmission opportunity. For example, the time value of the start position of the third CG transmission opportunity is summed with the difference between the time value of the end position of the measurement opportunity and the time value of the start position of the third CG transmission opportunity to obtain the time value of the start position of the fourth CG transmission opportunity.

[0189] In addition, the time domain position of the fourth CG transmission opportunity can also be determined in combination with the above two embodiments. For example, if the time domain position of the CG transmission opportunity determined by the terminal and / or access network device based on the time domain position of the third CG transmission opportunity and the time difference between the end position of the measurement opportunity and the start position of the third CG transmission opportunity still overlaps with the time domain position of the measurement opportunity, the time domain position of the fourth CG transmission opportunity finally adopted can be determined based on the end position of the measurement opportunity.

[0190] In another embodiment, the time interval between the fourth CG transmission opportunity and the third CG transmission opportunity may be fixed to the length of the measurement opportunity. For example, in this embodiment, the terminal and / or access network device may sum the time value of the starting position of the third CG transmission opportunity and the length value of the measurement opportunity to obtain the time value of the starting position of the fourth CG transmission opportunity.

[0191] It can be seen that based on Figure 5As shown in the process, in a communication method provided by the present application, the terminal and the access network device can transmit uplink information through the fourth CG transmission opportunity when the third CG transmission opportunity overlaps with the measurement opportunity in the time domain. The time interval between the fourth CG transmission opportunity and the third CG transmission opportunity can be determined according to the length or end position of the measurement opportunity. Therefore, when the third CG transmission opportunity overlaps with the measurement opportunity in the time domain, the uplink information can be transmitted in time through the fourth CG transmission opportunity, thereby reducing the service transmission delay.

[0192] in, Figure 5 The process shown is similar to Figure 3 The difference between the processes shown is that in S201, the third configuration information does not need to carry the time domain offset of the time interval between the third CG transmission opportunity and the fourth CG transmission opportunity; accordingly, the time domain position of the fourth CG transmission opportunity can be determined based on the time domain position of the third CG transmission opportunity and the length or end position of the measurement opportunity. Figure 3 The method shown can reduce the complexity of the configuration process and reduce signaling overhead.

[0193] Similar to the embodiment of S102, in an optional embodiment of S202, if the third CG transmission opportunity includes N2 CG transmission opportunities, and N2 is a positive integer greater than 1, the terminal can send uplink information to the access network device through the fourth CG transmission opportunity when at least K2 (or, more than K2) of the N2 CG transmission opportunities overlap with the measurement opportunity in the time domain. Correspondingly, the access network device can receive the uplink information sent by the terminal through the fourth CG transmission opportunity when at least K2 of the N2 CG transmission opportunities overlap with the measurement opportunity in the time domain. In this embodiment, K2 can be used as a threshold condition to trigger the execution of S202, that is, uplink information will only be sent through the fourth CG transmission opportunity when no less than K2 transmission opportunities overlap with the measurement opportunity in the time domain. The method of the present application may not be used in the transmission of low-priority logical channels to reduce complexity, and can give priority to the transmission performance of services with higher importance when resources are limited.

[0194] In this embodiment, the third configuration information can also be used to configure K2, for example, to configure the value of K2. Alternatively, the third configuration information can also be used to configure the ratio of K2 CG transmission opportunities to N2 CG transmission opportunities. In addition, it is not excluded that the access network device uses information or messages such as RRC signaling, MAC CE or DCI other than the third configuration information to configure K2 or the above ratio. K2 or the above ratio can also be pre-configured in the terminal and / or access network device through a protocol or factory configuration.

[0195] In another embodiment of S202, the uplink information sent by the terminal device to the access network device can be carried on a high-priority logical channel. In other words, if the uplink information is carried on a low-priority logical channel, the method shown in the present application can be ignored for sending. Referring to the description in S102, the priority of the logical channel can be determined according to the value of the priority field.

[0196] Figure 6 A flow chart corresponding to a communication method provided in an embodiment of the present application. Figure 6 The method shown is Figure 3 The method shown differs in that in Figure 6 The method shown is applied to downlink transmission based on SPS, and Figure 3 The method is applied to CG-based uplink transmission.

[0197] like Figure 6 As shown, the method may include the following steps:

[0198] S301: The access network device sends fourth configuration information and second configuration information to the terminal. Correspondingly, the terminal receives the fourth configuration information and the second configuration information.

[0199] The fourth configuration information may be used to configure the first SPS transmission opportunity and the second time offset. The first SPS transmission opportunity may include one or more SPS transmission opportunities within an SPS cycle period.

[0200] The second configuration information can be used to configure the measurement opportunity, and the measurement opportunity is used for inter-frequency measurement. The second configuration information and the measurement opportunity can refer to Figure 3 The instructions in the process will not be repeated here.

[0201] S302: When the first SPS transmission opportunity overlaps with the measurement opportunity in the time domain, the access network device sends downlink information to the terminal through the second SPS transmission opportunity. The time interval between the second SPS transmission opportunity and the first SPS transmission opportunity is equal to the first time offset. Therefore, the time domain position of the second SPS transmission opportunity can be determined according to the time domain position of the first SPS and the second time offset, as described below.

[0202] Among them, the downlink information may include downlink data of cloud gaming services and / or downlink data of XR services.

[0203] Correspondingly, when the first SPS transmission opportunity overlaps with the measurement opportunity in the time domain, the terminal receives downlink information from the access network device through the second SPS transmission opportunity.

[0204] It can be seen that based on Figure 6In the process shown in the present application, in a communication method provided by the present application, the terminal and the access network device can transmit downlink information through the second SPS transmission opportunity when the first SPS transmission opportunity overlaps with the measurement opportunity in the time domain. Among them, the time interval between the second SPS transmission opportunity and the first SPS transmission opportunity can be the first time offset configured by the access network device. Therefore, when the first SPS transmission opportunity overlaps with the measurement opportunity in the time domain, the downlink information can be transmitted in time through the second SPS transmission opportunity, thereby reducing the service transmission delay.

[0205] The fourth configuration information involved in S301 is described below.

[0206] In a possible embodiment, the fourth configuration information may be used to configure the SPS. For example, the fourth configuration information may be used to configure at least parameters such as the SPS period and the SPS time domain resources.

[0207] Specifically, the fourth configuration information may include a time domain resource configuration for indicating the first SPS transmission opportunity. For example, the fourth configuration information may also include a field in the DCI for indicating the SPS time domain resource, such as a resource allocation field, which may be used to indicate the location of the first SPS transmission opportunity. In addition, the fourth configuration information may also include a period field in the SPS configuration (SPS-Config) field.

[0208] It is understandable that the terminal can determine the time domain position of the first SPS transmission opportunity according to the resource allocation field and other fields used to indicate the SPS time domain resources, and the determination method does not belong to the limited content of this application. This application also does not limit the fourth configuration information to configure the SPS transmission opportunity in other ways.

[0209] Alternatively, when the SPS period configured by the fourth configuration information includes multiple SPS transmission opportunities, the fourth configuration information may also include the time intervals between the multiple SPS transmission opportunities. For example, when the multiple SPS transmission opportunities are distributed in equal time intervals, the fourth configuration information may include a parameter for indicating the time intervals between the multiple SPS transmission opportunities.

[0210] In addition, the fourth configuration information may also include a configuration of a second time offset, which is used to indicate the time interval between the second SPS transmission opportunity and the first SPS transmission opportunity. Therefore, the starting position of the second SPS transmission opportunity can be determined by the second time offset based on the starting position of the first SPS transmission opportunity. For example, the moment value of the time domain starting position of the second SPS transmission opportunity is the sum of the moment value of the time domain starting position of the first SPS transmission opportunity and the value of the second time offset. In S302, the second SPS transmission opportunity can be used to transmit downlink information. Optionally, the time domain length of the second SPS transmission opportunity may be the same as or different from the time domain length of the first SPS transmission opportunity, which is not specifically limited in this application. Among them, if the time domain length of the second SPS transmission opportunity is different from the time domain length of the first SPS transmission opportunity, the fourth configuration information may also include a configuration of the time domain length of the second SPS transmission opportunity; or, the time domain length of the second SPS transmission opportunity may adopt a default configuration, which may be determined in a predefined or preconfigured manner.

[0211] It can be understood that no matter whether the first SPS transmission opportunity includes one or more SPS transmission opportunities, the second SPS transmission opportunity may include one SPS transmission opportunity or multiple SPS transmission opportunities. If the second SPS transmission opportunity includes multiple SPS transmission opportunities, the second time offset may be used to indicate the time interval between the first SPS transmission opportunity in the second SPS transmission opportunity and the first SPS transmission opportunity.

[0212] It can also be understood that the number of SPS transmission opportunities included in the second SPS transmission opportunity may be the same as or different from the number of SPS transmission opportunities included in the first SPS transmission opportunity, and this application does not specifically limit it. For example, the first SPS transmission opportunity includes Q SPS transmission opportunities in an SPS cycle period, Q is a positive integer, and when the time interval between the end position of the first SPS transmission opportunity and the end position of the SPS cycle period is large, the second SPS transmission opportunity may include no less than Q SPS transmission opportunities. For another example, the first SPS transmission opportunity includes Q SPS transmission opportunities in an SPS cycle period, Q is a positive integer, and when the time interval between the end position of the first SPS transmission opportunity and the end position of the SPS cycle period is small, the second SPS transmission opportunity may include no more than Q SPS transmission opportunities.

[0213] In addition, the intervals between the multiple SPS transmission opportunities included in the second SPS transmission opportunity and the intervals between the multiple SPS transmission opportunities included in the first SPS transmission opportunity may be the same as or different from each other.

[0214] The temporal position relationship between the second SPS transmission opportunity and the first SPS transmission opportunity is similar to the temporal position relationship between the first CG transmission opportunity and the second CG transmission opportunity, so it can be referred to Figure 4 For example, you can Figure 4 The CG transmission opportunity in is replaced by the SPS transmission opportunity. For example, in the case where an SPS cycle period contains only one SPS transmission opportunity, the SPS transmission opportunity is the first SPS transmission opportunity, and the second time offset can be the time interval between the second SPS transmission opportunity and the first SPS transmission opportunity. For another example, in the case where an SPS cycle period contains multiple SPS transmission opportunities, the multiple SPS transmission opportunities are the first SPS transmission opportunity, and the second time offset can be the time interval between the second SPS transmission opportunity and the first SPS transmission opportunity among the multiple SPS transmission opportunities contained in the first SPS transmission opportunity.

[0215] Optionally, the fourth configuration information includes a semi-static scheduling-measurement interval-offset (SPS-MG-offset) field, whose value is the second time offset, that is, the SPS-MG-offset field can be used to configure the second time offset. It is not excluded that the second time offset is indicated in the fourth configuration information through other fields or by reusing existing fields.

[0216] The numerical range of the second time offset can refer to the numerical range of the first time offset. For example, the length of the second time offset is greater than or equal to the length of the measurement opportunity, or the value of the second time offset is not less than the length of the measurement opportunity; and / or the length of the second time offset is less than or equal to the length of the time interval between the end position of the SPS cycle period where the first SPS transmission opportunity is located and the end position of the first SPS transmission opportunity.

[0217] It can be understood that the access network device can determine the value of the first time offset according to the numerical range of the first time offset.

[0218] The value of the second time offset represents the time domain length of the second time offset. Therefore, the value range of the second time offset is equivalent to the length range of the second time offset.

[0219] In addition, the fourth configuration information may also include other parameters included in the SPS configuration, and reference may be made to the description of SPS parameters in this application, or to the description in the relevant communication standards or protocols.

[0220] Optionally, the fourth configuration information may be (or included in) high-level configuration signaling, such as an RRC message, or a MACCE, etc. For example, the fourth configuration information may include an SPS-Config field for configuring the SPS. In addition, it is not excluded that the fourth configuration information includes information in non-high-level configurations such as DCI, such as a resource allocation field, etc.

[0221] The following describes the manner in which the terminal and / or access network device determines whether the first SPS transmission opportunity overlaps with the measurement opportunity in the time domain in S302.

[0222] Similar to the implementation of S103, in one implementation of S302, the terminal and / or access network device can determine whether there is a time domain overlap between the first SPS transmission opportunity and the measurement opportunity based on the time domain position of the first SPS transmission opportunity and the time domain position of the measurement opportunity. The first SPS transmission opportunity can be determined based on the fourth configuration information, and the measurement opportunity can be determined based on the second configuration information. In another implementation of S302, the terminal and / or access network device can also determine whether there is a time domain overlap between the first SPS transmission opportunity and the measurement opportunity based on the fourth configuration information and the second configuration information, without first determining the time domain position of the first SPS transmission opportunity and the time domain position of the measurement opportunity.

[0223] It can be understood that in S302, when there is a time domain overlap between the first SPS transmission opportunity and the measurement opportunity, the terminal and / or access network device can determine the time domain position of the second SPS transmission opportunity based on the time domain position of the first SPS transmission opportunity and the first time offset, so as to transmit downlink information through the second SPS transmission opportunity.

[0224] In an optional embodiment of S302, if the first SPS transmission opportunity includes N3 SPS transmission opportunities, and N3 is a positive integer greater than 1, the access network device can send downlink information to the access network device through the second SPS transmission opportunity when at least K3 (or, more than K3) of the N3 SPS transmission opportunities overlap with the measurement opportunity in the time domain. Correspondingly, the terminal can receive downlink information through the second SPS transmission opportunity when at least K3 of the N3 SPS transmission opportunities overlap with the measurement opportunity in the time domain. In this embodiment, K3 can be used as a threshold condition to trigger the execution of S302, that is, downlink information will be transmitted through the second SPS transmission opportunity only when no less than K3 transmission opportunities overlap with the measurement opportunity in the time domain. The method of the present application may not be used in the transmission of low-priority logical channels to reduce complexity, and can give priority to the transmission performance of services with higher importance when resources are limited.

[0225] In this embodiment, the third configuration information may also be used to configure K3, for example, to configure the value of K3. Alternatively, the third configuration information may also be used to configure the ratio of K3 SPS transmission opportunities to N3 SPS transmission opportunities. In addition, it is not excluded that the access network device may configure K3 or the above ratio using information or messages such as RRC signaling, MAC CE or DCI other than the third configuration information. K3 or the above ratio may also be pre-configured in the terminal and / or access network device by means of a protocol or factory configuration.

[0226] In another embodiment of S302, the downlink information sent by the access network device to the terminal can be carried on a high-priority logical channel. In other words, if the downlink information is carried on a low-priority logical channel, the method shown in the present application can be ignored for sending. Referring to the description in S102, the priority of the logical channel can be determined according to the value of the priority field.

[0227] Figure 7 A flow chart corresponding to a communication method provided in an embodiment of the present application. Figure 7 The method shown is Figure 6 The method shown differs in that in Figure 7 In the method shown, the access network device does not need to configure the first time offset. In addition, when the SPS transmission timing overlaps with the measurement timing, the terminal and / or the access network device can determine the SPS transmission timing used for downlink transmission based on the length or end position of the measurement timing.

[0228] like Figure 7 As shown, the method may include the following steps:

[0229] S401: The access network device sends fifth configuration information and second configuration information to the terminal. Correspondingly, the terminal receives the fifth configuration information and the second configuration information.

[0230] The fifth configuration information may be used to configure a third SPS transmission opportunity. The third SPS transmission opportunity may include one or more SPS transmission opportunities within an SPS cycle period. The second configuration information may be used to configure a measurement opportunity. The second configuration information and the measurement opportunity may refer to the description in S101, which will not be repeated here.

[0231] The fifth configuration information is described below.

[0232] In a possible embodiment, the fifth configuration information may be used to configure the SPS. For example, the fifth configuration information may at least be used to configure parameters such as the SPS period and / or SPS time domain resources.

[0233] Specifically, the fifth configuration information may include a time domain resource configuration for indicating the third SPS transmission opportunity, and specific reference may be made to the description of configuring the first SPS transmission opportunity with the fourth configuration information in S301 of this application. For example, the fifth configuration information may also include a field in the DCI for indicating the SPS time domain resource, such as a resource allocation field, which may be used to indicate the location of the third SPS transmission opportunity.

[0234] Alternatively, when the SPS period configured by the fifth configuration information includes multiple SPS transmission opportunities, the fifth configuration information may also include the time intervals between the multiple SPS transmission opportunities. For example, when multiple SPS transmission opportunities are distributed in equal time intervals, the fifth configuration information may include a parameter for indicating the time intervals between the multiple SPS transmission opportunities.

[0235] It can be understood that the fifth configuration information may also include other parameters of the SPS configuration, and reference may be made to the description of the SPS parameters in this application, or to the description in the relevant communication standards or protocols.

[0236] Optionally, the fifth configuration information may be (or included in) high-level configuration signaling, such as an RRC message, or a MACCE, etc. For example, the fifth configuration information may include an SPS-Config field for configuring the SPS. In addition, it is not excluded that the fifth configuration information includes information in non-high-level configurations such as DCI, such as a resource allocation field, etc.

[0237] S402: When the third SPS transmission opportunity overlaps with the measurement opportunity in time domain, the access network device sends downlink information to the terminal through the fourth SPS transmission opportunity. Correspondingly, when the third SPS transmission opportunity overlaps with the measurement opportunity in time domain, the access network device receives downlink information sent by the terminal through the fourth SPS transmission opportunity.

[0238] In S402, the time interval between the fourth SPS transmission opportunity and the third SPS transmission opportunity is related to the length or end position of the measurement opportunity.

[0239] It can be understood that the way in which the terminal and / or access network equipment in S402 determines whether there is a time domain overlap between the third SPS transmission timing and the measurement timing can refer to the introduction of the way in which the first SPS transmission timing and the measurement timing are determined whether there is a time domain overlap in S102, and the repeated parts will not be repeated.

[0240] In S402, the end position of the measurement opportunity is related to the length of the measurement opportunity, or it can be said that the end position of the measurement opportunity can be determined according to the length of the measurement opportunity. For example, when the access network device configures the interval offset, MGRP and MG length of the MG, the time domain position of the measurement opportunity within the MG cycle period can be determined according to the interval offset, MGRP and MG length of the MG.

[0241] As a possible embodiment, the fourth SPS transmission opportunity may be the first downlink time slot after the measurement opportunity, so the time interval between the fourth SPS transmission opportunity and the third SPS transmission opportunity may be determined according to the end position of the measurement opportunity.

[0242] In this embodiment, the terminal and / or the access network device may determine the downlink time slot where the fourth SPS transmission opportunity is located according to the end position of the measurement opportunity that coincides with the third SPS transmission opportunity.

[0243] As another possible embodiment, the time interval between the fourth SPS transmission opportunity and the third SPS transmission opportunity may be equal to the time difference between the end position of the measurement opportunity and the start position of the third SPS transmission opportunity. That is, the time interval between the fourth SPS transmission opportunity and the third SPS transmission opportunity may satisfy:

[0244] The time interval between the fourth SPS transmission opportunity and the third SPS transmission opportunity=the time value of the end position of the measurement opportunity−the time value of the start position of the third SPS transmission opportunity.

[0245] In this embodiment, the terminal and / or access network device can determine the time domain position of the fourth SPS transmission opportunity based on the time domain position of the third SPS transmission opportunity and the time difference between the end position of the measurement opportunity and the start position of the third SPS transmission opportunity. For example, the time value of the start position of the third SPS transmission opportunity is summed with the difference between the time value of the end position of the measurement opportunity and the time value of the start position of the third SPS transmission opportunity to obtain the time value of the start position of the fourth SPS transmission opportunity.

[0246] In addition, the time domain position of the fourth SPS transmission opportunity can also be determined in combination with the above two embodiments. For example, if the time domain position of the SPS transmission opportunity determined by the terminal and / or access network device based on the time domain position of the third SPS transmission opportunity and the time difference between the end position of the measurement opportunity and the start position of the third SPS transmission opportunity still overlaps with the time domain position of the measurement opportunity, the time domain position of the fourth SPS transmission opportunity finally adopted can be determined based on the end position of the measurement opportunity.

[0247] In another embodiment, the time interval between the fourth SPS transmission opportunity and the third SPS transmission opportunity can be fixed to the length of the measurement opportunity. For example, in this embodiment, the terminal and / or access network device can sum the time value of the starting position of the third SPS transmission opportunity and the length value of the measurement opportunity to obtain the time value of the starting position of the fourth SPS transmission opportunity.

[0248] It can be seen that based on the process shown in the figure, in a communication method provided in the present application, the terminal and the access network device can transmit downlink information through the fourth SPS transmission opportunity when there is a time domain overlap between the third SPS transmission opportunity and the measurement opportunity. Among them, the time interval between the fourth SPS transmission opportunity and the third SPS transmission opportunity can be determined according to the length or end position of the measurement opportunity. Therefore, when there is a time domain overlap between the third SPS transmission opportunity and the measurement opportunity, the downlink information can be transmitted in time through the fourth SPS transmission opportunity, thereby reducing the service transmission delay.

[0249] in, Figure 7 The process shown is similar to Figure 6 The difference between the processes shown is that: in S401, the fifth configuration information does not need to carry the time domain offset of the time interval between the third SPS transmission opportunity and the fourth SPS transmission opportunity; accordingly, the time domain position of the fourth SPS transmission opportunity can be determined according to the time domain position of the third SPS transmission opportunity and the length or end position of the measurement opportunity. Figure 6 The method shown can reduce the complexity of the configuration process and reduce signaling overhead.

[0250] Similar to the embodiment of S102, in an optional embodiment of S402, if the third SPS transmission opportunity includes N4 SPS transmission opportunities, and N4 is a positive integer greater than 1, the terminal can send downlink information to the access network device through the fourth SPS transmission opportunity when at least K4 (or, more than K4) of the N4 SPS transmission opportunities overlap with the measurement opportunity in the time domain. Correspondingly, the access network device can receive the downlink information sent by the terminal through the fourth SPS transmission opportunity when at least K4 of the N4 SPS transmission opportunities overlap with the measurement opportunity in the time domain. In this embodiment, K4 can be used as a threshold condition to trigger the execution of S402, that is, downlink information will be sent through the fourth SPS transmission opportunity only when no less than K4 transmission opportunities overlap with the measurement opportunity in the time domain. The method of the present application may not be used in the transmission of low-priority logical channels to reduce complexity, and can give priority to the transmission performance of services with higher importance when resources are limited.

[0251] In this embodiment, the fifth configuration information may also be used to configure K4, for example, to configure the value of K4. Alternatively, the fifth configuration information may also be used to configure the ratio of K4 SPS transmission opportunities to N4 SPS transmission opportunities. In addition, it is not excluded that the access network device may configure K4 or the above ratio using information or messages such as RRC signaling, MAC CE or DCI other than the fifth configuration information. K4 or the above ratio may also be pre-configured in the terminal and / or access network device by means of a protocol or factory configuration.

[0252] In another embodiment of S402, the downlink information sent by the terminal device to the access network device can be carried on a high-priority logical channel. In other words, if the downlink information is carried on a low-priority logical channel, the method shown in the present application can be ignored for sending. Referring to the description in S102, the priority of the logical channel can be determined according to the value of the priority field.
