Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method and device based on indicating unused transmission opportunities in a configured grant (CG) method. Background Art

[0002] With the continuous development of the fifth generation mobile communication technology (5G), data transmission delay is reduced, and transmission capacity is increasing. Some multimedia services with strong real-time requirements and large data capacity requirements have emerged, such as video transmission, cloud gaming (CG) and extended reality (XR) services, such as virtual reality (VR) services or augmented reality (AR) services. The service characteristics are that the arrival of uplink and / or downlink data packets is periodic and the interval time is short. For example, if the frame rate of an XR service is 60 frames per second, the average time interval between the arrival of two adjacent data packets is 16.67 milliseconds (ms) without considering the transmission delay.

[0003] For uplink periodic transmission services, the network device can configure the CG transmission opportunity in the CG cycle period for the terminal through uplink scheduling configuration (configured scheduling, CS) or CG. Subsequently, the terminal can send the data to be sent to the network device through the CG transmission opportunity. In order to allow the data to be sent to have the corresponding CG transmission opportunity to carry, the network device usually configures more CG transmission opportunities for the terminal in the CG cycle period, which will lead to a waste of resources.

[0004] To reduce resource waste, the terminal can send indication information to the network device, such as unused transmission occasions (UTO) uplink control information (UCI), to indicate the CG transmission occasions that the terminal does not use. However, the existing UTO-UCI detection efficiency is low. Summary of the invention

[0005] The present application provides a communication method and device, which improves the detection efficiency of unused CG transmission opportunity indication information on the network device side and reduces the complexity of detecting the information, thereby improving communication efficiency.

[0006] In order to achieve the above objectives, this application adopts the following technical solutions:

[0007] In a first aspect, a communication method is provided, which can be executed by a terminal or by a module (such as a chip or circuit) of the terminal. The method includes: receiving first configuration information from a network device, the first configuration information is used to configure N time units within an authorized CG cycle period, wherein the N time units include time units corresponding to CG transmission opportunities; sending first indication information to the network device, the first indication information indicates the occupancy of CG transmission opportunities within the CG cycle period, wherein the number of bits occupied by the first indication information is L, L is associated with the duration of the CG cycle period, and L and N are positive integers.

[0008] In the above implementation, the length of the first indication information is agreed upon by the terminal side and the network device, so that the first indication information is a fixed length of L information bits, so that the network device side can determine the length of the first indication information as L according to the duration of the CG cycle period, which can reduce the complexity of the network device's blind detection of the first indication information, that is, no matter how many valid CG transmission opportunities the first indication information is used to indicate, the length of the first indication information is fixed, or it is a fixed length negotiated by the terminal and the network device, thereby improving the detection efficiency of the network device in detecting the first indication information and reducing the complexity of the network device.

[0009] In one embodiment, L is also associated with the time division duplexing (TDD) uplink and downlink configuration. For the TDD mode, different uplink and downlink configurations determine the number of CG transmission opportunities within the CG cycle period. Therefore, the length L of the first indication information is also associated with the uplink and downlink configuration of TDD, that is, the terminal and the network device can respectively determine the length of the first indication information as L according to the uplink and downlink configuration of TDD and the duration of the CG cycle period, thereby improving the detection efficiency of the network device in detecting the first indication information, and improving the flexibility and reliability of the first indication information.

In other words, the length L of the first indication information can be set to the maximum value of the number of CG transmission opportunities in the K CG cycle periods, that is, the network device and the terminal can respectively determine the length of the first indication information according to multiple (such as K) CG cycle periods, in which the number of CG transmission opportunities is the largest, thereby improving the detection efficiency of the network device in detecting the first indication information, and improving the flexibility and reliability of the first indication information.

[0014] In the above implementation, the network device configures the indication length of the third indication information for the terminal through a displayed indication method, so that the terminal can generate a third indication information of a fixed length according to the indication of the network device, which is used to indicate the occupancy of the CG transmission opportunity within the CG cycle period, thereby reducing the complexity of the network device's blind detection of the third indication information, that is, no matter how many valid CG transmission opportunities the third indication information is used to indicate, the length of the third indication information is a fixed length negotiated by the terminal and the network device, thereby improving the detection efficiency of the network device in detecting the third indication information and reducing the complexity of the network device.

[0015] In one embodiment, the minimum value of P is also associated with the time division duplex TDD uplink and downlink configuration. For the TDD mode, different uplink and downlink configurations determine the number of CG transmission opportunities within the CG cycle period.

[0058] Before introducing the technical solution of the present application, the relevant technical terms and processes involved in the present application are explained. It is understandable that these explanations are intended to make the present application easier to understand and should not be regarded as limiting the scope of protection claimed by the present application.

[0059] 1. Extended reality (XR)

[0060] XR can refer to various environments that combine reality and virtuality, as well as interactions between people and machines, generated by computing technology and wearable devices. It has advantages such as multiple perspectives and strong interactivity, and can provide users with a new experience. It has great application value and commercial potential. XR mainly includes virtual reality (VR) and augmented reality (AR) and other virtual and real interaction technologies, which can be widely used in entertainment, games, medical treatment, advertising, industry, online education, engineering and many other fields. The following introduces VR technology and AR technology respectively.

[0061] VR technology combines computer graphics, multimedia and other technologies to simulate the functions of human visual, auditory, tactile and other sensory organs, making people feel as if they are in the virtual world generated by the computer, and can communicate in real time through language, gestures, etc., to enhance the sense of immersion. Through VR technology, people can feel the real world realistically while breaking through the limitations of time and space and other conditions, and feel the wonderful experience of entering the virtual world. VR technology usually requires users to wear XR terminals (such as head-mounted devices) to simulate vision and / or hearing and / or touch to users. VR technology can also track the user's movements, so as to update the simulated visual and / or auditory and / or tactile content in a timely manner. For example, VR technology can process the user's status information (such as the user's position information and posture information) to display the scene content corresponding to the user's status information on the XR terminal.

[0062] AR technology can use computer technology to superimpose virtual information on the real world, display it through mobile phones, tablets, glasses and other devices, and be perceived by people, thereby realizing the integration of reality and virtuality and enriching the real world. In short, it is to give more information to physical objects, enhance the three-dimensional sense, and strengthen the visual effect and interactive experience. For example, AR technology can process the perceived visual information (usually the visual information includes depth information) to integrate virtual information with the real world and be perceived by users, thereby achieving "enhancement" of the real world.

[0063] 2. Cloud VR and Cloud AR

[0064] Cloud virtual reality is the application of cloud computing and cloud rendering concepts and technologies to VR services, while cloud augmented reality is the application of cloud computing and cloud rendering concepts and technologies to AR services. Both cloud virtual reality and cloud augmented reality can use high-speed and stable networks to send information in the real world perceived by the terminal to the cloud (such as sending it to the cloud through a base station). The cloud processes the received information to obtain encoded and compressed information such as display output and sound output, and sends the information to the terminal with the help of a high-speed and stable network (such as sending it to the terminal through a base station), thereby realizing the cloud-based VR / AR service content and rendering, and further realizing the market demand for lightweight and mobile terminals.

[0065] It is understandable that in the above-mentioned video transmission service, such as the process in which the terminal sends the perceived real-world information to the cloud, or the process in which the cloud sends the processed display output and sound output and other encoded and compressed information to the terminal, the data to be sent is usually sent periodically according to the frame rate, and the data volume is usually large. Take a video with a frame rate of 60 frames per second (FPS) as an example. Figure 1 As shown, one video frame arrives every 16.67 milliseconds (ms). If the video frame is a 4K video frame, the size of the video frame is about 30 to 100 KB. In addition, the sizes of different video frames are usually different, and due to different compression rates and frame types of different video frames, the sizes of different video frames may vary greatly.

[0066] It is understandable that cloud virtual reality and cloud augmented reality have different characteristics, so their business models are also different. Specifically, in cloud virtual reality services, changes in scene content display are related to the user's posture or position (action). Therefore, the terminal mainly sends the user's location information and posture information to the cloud, with a small amount of data and a network uplink rate of about tens of kbps. The cloud sends mainly rendered video streams to the terminal, with a relatively large amount of data, and the network downlink rate can reach tens to hundreds of Mbps. Unlike cloud virtual reality services, in cloud augmented reality services, changes in scene content display are related to changes in the user's gaze focus target and changes in the spatial relationship between the user's position and the gaze focus target (such as changes in the spatial relationship caused by user actions). Therefore, the terminal mainly sends to the cloud the perceived visual information (which contains depth information), such as clear and stable pictures or video streams, or environmental feature information extracted from the visual information, with a large amount of data. For example, the network uplink rate required to meet the initial experience of cloud augmented reality services is usually about 2Mbps, and the network uplink rate required to meet the advanced experience is about 10 to 20Mbps. The size of the data sent from the cloud to the terminal is small. In summary, cloud virtual reality services have higher requirements for downlink transmission rates, while cloud augmented reality services have higher requirements for uplink transmission rates.

[0067] 3. CG

[0068] A network device (such as a radio access network (RAN) node) can configure periodic uplink resources for a terminal in a CG manner. Afterwards, the terminal can periodically reuse the uplink resources for uplink transmission. For example, the network device can configure periodic uplink resources for the terminal in the following manner 1 or manner 2.

[0069] Method 1: The network device configures and activates CG resources for the terminal.

[0070] The network device sends configuration information to the terminal. Correspondingly, the terminal obtains the configuration information. Exemplarily, the network device can configure and activate CG resources for the terminal through a radio resource control layer (RRC) message. The RRC message may include information about the CG cycle period and information about multiple CG transmission occasions (CG occasions) in a CG cycle period. In this application, the CG transmission occasion can be understood as the time-frequency resources of the CG or the time domain resources of the CG, which are used to transmit uplink data.

[0071] In the present application, the CG transmission opportunity may also have other naming methods, for example, CG transmission opportunity, CG physical uplink shared channel (physical uplink shared channel, PUSCH) transmission opportunity or CG PUSCH transmission opportunity, etc., without limitation.

[0072] Optionally, the RRC message may also include an indication information, which is used to indicate the activation of the above-mentioned CG resources.

[0073] It can be understood that after receiving the RRC message, the terminal can periodically use the above-mentioned multiple CG transmission opportunities for uplink transmission.

[0074] As an example, the CG resources configured and activated by the network device for the terminal can be as follows: Figure 2 shown. Figure 2 FIG. 4 shows multiple CG transmission opportunities within two CG cycle periods. Figure 2 In the example, the network device sends an RRC message to the terminal at time 1. The RRC message configures the CG cycle period and four CG transmission opportunities within a CG cycle period. After receiving the RRC message, the terminal can send data to the network device during the CG cycle period through the CG transmission opportunity within the CG cycle period.

[0075] Method 2: The network device configures CG resources for the terminal and then activates the CG resources through indication information.

[0076] Step 1: The network device sends configuration information to the terminal. Correspondingly, the terminal obtains the configuration information.

[0077] The configuration information is used to configure CG resources. For example, the configuration information includes information about a CG cycle period and information about multiple CG transmission opportunities in a CG cycle period.

[0078] A possible design is that the configuration information is carried in an RRC message.

[0079] Step 2: The network device sends instruction information to the terminal, and the terminal obtains the instruction information accordingly.

[0080] Among them, the indication information is used to indicate the CG resources configured by the activation configuration information.

[0081] In a possible implementation manner, the indication information may be carried in downlink control information (DCI).

[0082] It can be understood that after the terminal obtains the configuration information and indication information, it can periodically use the multiple CG transmission opportunities configured by the configuration information to perform uplink transmission.

[0083] From the above introduction, it can be understood that by adopting the CG method, the network device can configure periodically repeated CG resources for the terminal through one resource allocation. Therefore, the size of data that can be carried by CG resources in different CG periodic periods is the same. For example, Figure 2 In the example, the size of data that can be carried by the first four CG transmission opportunities is the same as the size of data that can be carried by the last four CG transmission opportunities. However, the size of the data to be sent in different CG cycle periods may be different. For example, the previous article described in the introduction of cloud virtual reality and cloud augmented reality that the size of different video frames is usually variable, and due to the different compression rates and frame types of different video frames, the size of different video frames will be quite different. This results in the size of the data to be sent in some CG cycle periods (such as CG cycle period 1) being larger, and the size of the data to be sent in some CG cycle periods (such as CG cycle period 2) being smaller. Then, in CG cycle period 1, the data to be sent may occupy all CG transmission opportunities in this period, and the resources in this period are not wasted. In CG cycle period 2, the data to be sent may occupy part of the CG transmission opportunities in this period, and the CG transmission opportunities not occupied by the data to be sent in this period do not transmit data and are wasted.

[0084] In order to save resources, it is possible to allow the terminal to report to the network device the CG transmission occasions that have not been used for a period of time, so that the network device can reallocate these unused CG transmission occasions, such as allocating them to other services of the terminal, or to other terminals, etc., to reduce the waste of resources. Specifically, the terminal can report to the network device the unused transmission occasions (UTO) that have not been used for a period of time, that is, UTO indication information, according to predefined rules; or, the network device configures the method of reporting UTO for the terminal, and the terminal can send UTO indication information to the network device according to the method configured by the network device.

[0085] Exemplarily, the terminal may send UTO indication information to the network device at one or more CG transmission opportunities within the CG cycle period. Correspondingly, the network device receives the UTO indication information at the corresponding CG transmission opportunity within the CG cycle period. The UTO indication information is used to indicate the CG transmission opportunity that is not used within the CG cycle period. Optionally, the UTO indication information may be carried on uplink control information (UCI), referred to as UTO-UCI.

[0086] like Figure 3 As shown, 4 CG PUSCHs are configured in one CG cycle period. The terminal can send UTO-UCI on the first CG PUSCH to inform the network device of the resource occupancy of the CG PUSCH in this CG cycle period. For example, if the first two CGPUSCHs are occupied, the last two CG PUSCHs are no longer occupied.

[0087] The implementation methods of the present application are described in detail below with reference to the accompanying drawings.

[0088] The method provided in this application can be used in various communication systems. Figure 4 The method provided in the present application is described by taking the communication system 10 as an example. Figure 4 It is only a schematic diagram and does not constitute a limitation on the applicable scenarios of the technical solution provided in this application.

[0089] Figure 4 FIG. 1 is a schematic diagram showing a possible, non-limiting system. Figure 4 As shown, the communication system 10 includes a RAN 100 and a core network (CN) 200. The RAN 100 includes at least one RAN node (e.g. Figure 4 110a and 110b, collectively referred to as 110) and at least one terminal (such as Figure 4RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment ( Figure 4 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.

[0090] 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.

[0091] The RAN node 110, which may also be sometimes referred to as an access network device, a RAN entity, a network device 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 4 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 4 The network elements 110a and 110b may be understood as communication devices having base station functions, and the network elements 120a-120j may be understood as communication devices having terminal functions.

[0092] In one possible scenario, a RAN node may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), 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 4 110a in), micro base stations or indoor stations (such as Figure 4 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.

[0093] 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 central unit (CU), DU, CU-control plane (CP), CU-user plane (UP), or RU, etc. 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).

[0094] 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.

[0095] 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.

[0096] The terminal can also be a VR terminal, an AR terminal, or a mixed reality (MR) terminal. VR terminals, AR terminals, and MR terminals can all be called extended reality terminals. The XR terminal can be, for example, a head-mounted device (such as a helmet, a head mounted display (HMD) or glasses), or an all-in-one machine, or a TV, a monitor, a car, a vehicle-mounted device, a tablet or a smart screen. The XR terminal can access the network wirelessly or wired, for example, through a WiFi or 5G system. The XR terminal can present XR data to the user, and the user can experience a variety of XR services by wearing or using the XR terminal.

Those skilled in the art should understand that in the specific implementation process, the communication system 10 may also include other devices, and the number of RAN nodes and terminals may also be determined according to specific needs without limitation.

[0126] like Figure 6 As shown, a communication method provided by the present application may include the following steps:

[0127] 601: The network device sends first configuration information to the terminal.

[0128] Among them, the first configuration information is used to configure the CG cycle period, and at least N time units included in the CG cycle period, the N time units include the time units corresponding to the CG transmission timing, and N is a positive integer. The first configuration information can be used to configure a CG cycle period, and can also be used to configure multiple periodic CG cycle periods. N is defined as the number of time units allocated to the terminal for determining PUSCH in the CG cycle period.

[0129] It should be noted that in this application, a time unit may be a time domain unit such as a time slot, a symbol or a mini time slot. In subsequent embodiments, a time slot is used as an example of a time unit, and this application does not specifically limit this. In addition, the duration of the CG cycle period may be equal to or greater than the duration of N time units, and the CG cycle period may also include time units other than the N time units configured by the network device, and this application does not limit this.

[0130] That is to say, a CG cycle period may include at least N time units, wherein the N time units include at least one time unit corresponding to one or more CG transmission opportunities.

[0131] Specifically, the duration of a CG cycle period is equal to the duration of the CG cycle. For example, the duration of multiple CG cycle periods configured by the first configuration information is T milliseconds (ms), and the starting time slot of the first CG cycle period is T1. Then, it can be determined that the configured first CG cycle period can be [T1, T1+T-1], and the second CG cycle period can be [T1+T, T1+2T-1]. For example, Figure 7As shown, if T=17ms, the length of a time slot is 1ms, N is 17, T1 is time slot 0, CG cycle period 1 includes time slot 0 to time slot 16, and CG cycle period 2 includes time slot 17 to time slot 33.

[0132] It should be noted that the duration of multiple CG resources may be the same, or may be different. For example, the network device may configure three CG cycle periods for the terminal, and the duration of these three CG cycle periods may be 16 time slots, 16 time slots, and 17 time slots, respectively. This application does not make specific restrictions on this. For ease of description, unless otherwise specified, the duration of multiple CG cycle periods in the following embodiments may be the same.

[0133] In one implementation, the first configuration information may configure the period of the CG, such as the first configuration information includes a parameter N. Optionally, the first configuration information may also include time domain information or frequency domain information corresponding to the CG resources.

[0134] Among them, the N time units include the time units corresponding to the CG transmission opportunities. Specifically, a CG cycle period may include one or more CG transmission opportunities for the terminal to perform uplink transmission. Among them, one CG transmission opportunity can be carried in one time unit, or multiple CG transmission opportunities can be carried in one time unit. It can be seen that a CG cycle period may include one or more time units for uplink transmission.

[0135] Specifically, the embodiments of the present application can be applied to a time division duplexing (TDD) mode or a frequency division duplexing (FDD) mode. For the FDD mode, uplink transmission and downlink transmission use different radio frequency bands. For example, a CG resource is configured to include 17 time slots, all of which are used for uplink transmission. If an uplink time slot U corresponds to a CG transmission opportunity, the CG cycle period includes 17 CG transmission opportunities.

[0136] For the TDD mode, uplink transmission and downlink transmission can share the same radio frequency band, wherein uplink transmission or downlink transmission can use different time units. Specifically, the TDD mode may include specific uplink and downlink configurations, i.e., a configuration ratio or configuration rule for indicating the time units corresponding to downlink transmission and uplink transmission, for example, the uplink and downlink configurations may be DDUDD or DDDU, etc.

[0137] For example, Figure 7As shown, N is 17 (the time unit is a time slot), that is, the CG period configured by the network device for the terminal includes 17 consecutive time slots, wherein, if one uplink time slot U corresponds to one CG transmission opportunity, and the ratio of the downlink time slot D to the uplink time slot U in the CG period is 4:1, if the specific uplink and downlink configuration is DDUDD, then Figure 7 As shown, the downlink time slot D and the uplink time slot U in the CG cycle period can be arranged in the order of DDUDD, and the CG transmission opportunities included in the CG cycle period 1 can be carried in the three time slots of time slot 2, time slot 7 and time slot 12. The CG transmission opportunities included in the CG cycle period 2 can be carried in the four time slots of time slot 17, time slot 22, time slot 27 and time slot 32. In other words, the number of CG transmission opportunities in the CG cycle period 1 can be 3, and the number of CG transmission opportunities in the CG cycle period 2 can be 4.

[0138] Optionally, the first configuration information may be carried in an RRC message.

[0139] Correspondingly, the terminal receives the first configuration information from the network device, obtains the CG resource from the first configuration information, that is, determines that the CG cycle period includes at least N time units, and determines one or more time units corresponding to the CG transmission opportunity included in the N time units. Thus, the terminal can perform uplink transmission through the CG transmission opportunity.

[0140] 602: The terminal sends first indication information to the network device.

[0141] Among them, the first indication information indicates the occupancy status of the CG transmission opportunity within the CG cycle period. Specifically, the first indication information can indicate the occupancy status of one or more CG transmission opportunities within a CG cycle period. The occupancy status of the CG transmission opportunity refers to whether the terminal actually occupies or does not occupy each CG transmission opportunity configured by the network device for it.

[0142] For example, the terminal can determine the number of CG transmission opportunities used in a CG cycle period according to the size of the data to be sent, that is, determine whether each CG transmission opportunity in the CG cycle period is occupied or unoccupied, and then send a first indication information to the network device, so that the network device can reallocate unoccupied CG transmission opportunities to reduce resource waste.

[0143] Specifically, the number of bits occupied by the first indication information is L, L is associated with the duration of the CG cycle period, and L is a positive integer. That is, the length of the first indication information sent by the terminal to the network device is L bits (L bits), where L can be determined by the terminal according to the duration of the CG cycle period indicated in the first configuration information configured by the network device.

[0144] Among them, the length of the first indication information is fixed, which is L bits, wherein one bit of the first indication information can be used to indicate the resource occupancy status of a CG transmission opportunity, including occupied or not occupied. Exemplarily, a bit value of 1 can indicate that the CG transmission opportunity is occupied; a bit value of 0 can indicate that the CG transmission opportunity is not occupied. Alternatively, a bit value of 0 can indicate that the CG transmission opportunity is occupied; a bit value of 1 can indicate that the CG transmission opportunity is not occupied. This application does not make any specific limitation on this.

[0145] It should be noted that the L bits included in the first indication information can be used to indicate the resource occupancy of no more than L CG transmission opportunities, wherein the first indication information may include some bits as reserved bits. For example, when the L bits included in the first indication information are used to indicate the resource occupancy of L1 CG transmission opportunities, wherein L1 is less than L, then the L-L1 bits therein are reserved bits, or unused bits, and these L-L1 bits can be filled according to predefined rules, such as uniformly filled with 0 or 1.

[0146] Optionally, the first indication information may be carried on the UCI. Specifically, the terminal may send the UCI carrying the first indication information through a CG transmission opportunity configured by the network device.

[0147] In one embodiment, the terminal may send first indication information corresponding to a first CG cycle period to a network device at a first moment, wherein the first moment may be a CG transmission opportunity within the first CG cycle period, or the first moment may also be a CG transmission opportunity within other CG cycle periods, such as a CG transmission opportunity within a CG cycle period before the first CG cycle period.

[0148] That is to say, the first indication information may indicate the resource occupancy status within the CG cycle period corresponding to the CG transmission opportunity occupied by the first indication information, or the first indication information may also indicate the resource occupancy status of other CG cycle periods, such as the resource occupancy status of the next CG cycle period of the CG cycle period in which the first indication information is sent.

[0149] Exemplarily, within CG cycle period 1, including CG transmission opportunity 1, the terminal sends a first indication information to the network device through the CG transmission opportunity 1, which is used to indicate the resource occupancy status of CG cycle period 1, or to indicate the resource occupancy status of CG cycle period 1 and CG cycle period 2.

[0150] Correspondingly, the network device receives the first indication information from the terminal. Thus, the network device can determine the occupancy of the CG transmission opportunity within the CG cycle period according to the content included in the first indication information, and can reallocate the unoccupied CG transmission opportunity to reduce resource waste.

[0151] In the above-mentioned implementation mode of the present application, the length of the first indication information is agreed upon by the terminal side and the network device, so that the first indication information is a fixed length of L information bits, which can reduce the complexity of the network device's blind detection of the first indication information, that is, no matter how many valid CG transmission opportunities the first indication information is used to indicate, the length of the first indication information is fixed, or it is a fixed length negotiated by the terminal and the network device, thereby improving the detection efficiency of the network device in detecting the first indication information and reducing the complexity of the network device.

[0152] In one embodiment, the network device may configure CG resources for the terminal according to the data volume of the XR frame corresponding to the terminal. For example, the network device configures K CG cycle periods for the terminal through the first configuration information, which can be specifically numbered as CG cycle period 1 to CG cycle period k, where k is {1, 2, ..., K}, and K is a positive integer greater than 1. The number of CG transmission opportunities included in each CG cycle period can be represented by M, that is, the number of CG transmission opportunities in CG cycle period k is represented by M. k , then the number of CG transmission opportunities corresponding to K CG cycle periods can be {M 1 , M 2 , …M k , …, M K}.

[0153] In one implementation, the length L of the first indication information may be: L=max{M 1 , M 2 , …M k , …, M K},M k It represents the number of CG transmission opportunities in CG cycle period k, where CG cycle period k is one of K CG cycle periods, and the duration of the K CG cycle periods is configured by the first configuration information. max{M(k)} is used to represent the maximum value of the sequence M(k).

[0154] In one implementation, for the FDD mode, if all time units included in a CG cycle period are used for uplink transmission, the length L of the first indication information can be obtained according to the duration of one or more CG cycle periods. Specifically, the length of the first indication information can be set according to the number of CG transmission opportunities in one or more CG cycle periods.

[0155] For example, in FDD mode, K CG cycle periods include at least N time units. If a CG transmission opportunity is carried in one time unit, the number of CG transmission opportunities corresponding to each CG cycle period in the K CG cycle periods is M. k If both are N, then L can be set to the duration of the CG period, that is, L = N. If each CG transmission opportunity corresponds to i time units, then the M corresponding to each CG period in the K CG period is k It can be N / i, then L can be set to: L = N / i. If j CG transmission opportunities correspond to one time unit, then the M corresponding to each CG period in the K CG period is k It can be N*j, then L can be set to: L=N*j. In the above examples, i and j are both positive integers.

[0156] In another example, one CG transmission opportunity corresponds to one time slot. If the durations of the three CG cycle periods in FDD mode are respectively, CG cycle period-1 includes 16 time slots, CG cycle period-2 includes 16 time slots, and CG cycle period-3 includes 17 time slots, then it can be obtained that the number of CG transmission opportunities corresponding to CG cycle period-1 is M 1 =16, the number of CG transmission opportunities corresponding to the CG cycle period -2 is M 2 =16, the number of CG transmission opportunities corresponding to the CG cycle period -3 is M 3 =17, then the length L of the first indication information can be set to 17, so as to meet the requirement that the first indication information indicates the resource occupancy of each CG transmission opportunity in each CG cycle period, thereby improving the flexibility and reliability of the indication information.

[0157] In one implementation, for the TDD mode, the length L of the first indication information is also associated with the uplink and downlink configuration of the TDD mode. That is, in the TDD mode, the length L of the first indication information can be obtained based on the duration of at least one CG cycle period and the uplink and downlink configuration of the TDD mode. Specifically, in combination with the foregoing: the value of the length L of the first indication information can be: L = max{M 1 , M 2 , …M k , …, M K It can be seen that the length L of the first indication information can be the maximum value of the number of CG transmission opportunities corresponding to multiple CG cycle time periods.

[0158] For example, the duration of the CG cycle period is equal to 17 time slots, and one CG transmission opportunity corresponds to one time slot. Figure 7As shown in , if the uplink and downlink configuration of the TDD mode is DDUDD, the difference between two adjacent Us is 5 time slots. It can be obtained that the number of U time slots contained in a CG cycle period may be 3 or 4, and the maximum value is 4. Then the number of bits of the first indication information can be set to 4. Similarly, if the uplink and downlink configuration of the TDD mode is DDDU, such as Figure 8 As shown, there is a difference of 4 time slots between two adjacent Us. It can be obtained that the number of U time slots contained in a CG cycle period may be 4 or 5, and the maximum value is 5. Then the number of bits of the first indication information can be set to 5.

[0159] Specifically, the bit sequence u of the first indication information M-1 ,…,u 1 ,u 0 , can be mapped according to the timing sequence of the CG transmission opportunities included in the CG cycle period, and the mapping order is: according to the timing of each CG transmission opportunity from front to back, the corresponding mapping to the first indication information bit sequence is mapped from the most significant bit (MSB) to the least significant bit (LSB), where u 0 is LSB, u M-1 The unused bits can be filled with 0 or 1.

[0160] According to the above example, Figure 7 As shown, if the value of the bit in the first indication information is 0, it indicates that the terminal is occupying the resources of the CG transmission opportunity; the value is 1, which indicates that the terminal is not occupying the resources of the CG transmission opportunity. The remaining bits can be filled with 0. Taking the uplink and downlink configuration of the TDD mode as DDUDD as an example, in CG cycle period 1, the terminal occupies all 3 CG transmission opportunities, and in CG cycle period 2, the terminal only occupies the first 2 CG transmission opportunities, then the first indication information corresponding to CG cycle period 1 can be 0000, and the first indication information corresponding to CG cycle period 2 can be 0011.

[0161] It can be seen from the above embodiments that when the network device configures CG resources for the terminal and the uplink and downlink configurations of the TDD mode are known, the network device can obtain the maximum number of CG transmission opportunities contained in multiple CG cycle time periods, that is, the number of bits of the first indication information can be obtained, thereby reducing the complexity of the network device detecting the first indication information. In addition, the first indication information only includes the resource occupancy corresponding to the CG transmission opportunity, with less redundant information and less signaling overhead of the first indication information.

[0162] In addition, the present application also provides a communication method, such as Fig. 9 As shown, the method may include the following steps:

[0163] 901: The network device sends first configuration information to the terminal.

[0164] Correspondingly, the terminal receives the first configuration information from the network device.

[0165] The first configuration information is used to configure at least N time units included in the CG cycle period, including one or more time units corresponding to at least one CG transmission opportunity.

[0166] For details, please refer to the description of the aforementioned step 601, which will not be repeated here.

[0167] 902: The terminal sends second indication information to the network device.

[0168] Correspondingly, the network device receives second indication information from the terminal.

[0169] The second indication information indicates the occupancy status of the CG transmission opportunity within the CG cycle period, and the number of bits occupied by the second indication information is N, where N is a positive integer.

[0170] That is, the second indication information can be set to the number N of time units in the CG cycle period configured by the network device for the terminal.

[0171] Optionally, the first indication information may be carried on UCI, which is UTO-UCI.

[0172] For FDD mode, if all time units included in a CG cycle period are used for uplink transmission, and one time unit corresponds to one CG transmission opportunity, the length of the first indication information can be determined according to the duration of the CG cycle period. Specifically, if the CG cycle period includes at least N time units, the length of the second indication information is N bits.

[0173] For the TDD mode, if one time unit corresponds to one CG transmission opportunity, and one or more CG transmission opportunities are included in the N time units within a CG cycle period, the length of the first indication information can be determined according to the duration of the CG cycle period, that is, the length of the second indication information is N bits. Among them, if the N time units within the CG cycle period only include one CG transmission opportunity, one bit in the second indication information is used to indicate whether the resource occupancy of the CG transmission opportunity is occupied or not occupied, and the other N-1 bits are uniformly filled with 0 or 1, which is redundant information. If the N time units within the CG cycle period only include M CG transmission opportunities, where M is a positive integer less than or equal to N, the M bits in the second indication information are used to indicate whether the resource occupancy of the CG transmission opportunity is occupied or not occupied, and the other NM bits are uniformly filled with 0 or 1, which is redundant information.

[0174] Specifically, the bit sequence u of the second indication information M-1 ,…,u 1 ,u 0 , can be mapped according to the timing sequence of at least N time units included in the CG cycle period, and the mapping order is: according to the timing corresponding to each CG transmission opportunity from front to back, the corresponding second indication information bit sequence is mapped from the most significant bit (most significant bit, MSB) to the least significant bit (least significant bit, LSB), where u 0 is LSB, u M-1 The unused bits can be filled with 0 or 1.

[0175] For example, Figure 8 For example, if the value of the bit in the second indication information is 0, it indicates that the terminal is occupying the resources of the CG transmission opportunity; the value is 1, which indicates that the terminal is not occupying the resources of the CG transmission opportunity. The remaining bits can be filled with 1. In CG cycle period 1, the terminal occupies 3 CG transmission opportunities, and in CG cycle period 2, the terminal only occupies the first 2 CG transmission opportunities. The second indication information occupies 17 bits. The second indication information corresponding to CG cycle period 1 can be: 000111111111111111, and the second indication information corresponding to CG cycle period 2 can be: 001111111111111111.

[0176] In the above-mentioned implementation mode of the present application, the length of the second indication information (such as UTO-UCI) is agreed upon by the terminal side and the network device, so that the length of the second indication information is fixed to the length of the CG cycle period, thereby reducing the complexity of the network device's blind detection of the second indication information, that is, regardless of the second indication information is used to indicate the resource occupancy of several valid CG transmission opportunities, the length of the second indication information is fixed, or is a fixed length negotiated by the terminal and the network device, thereby improving the detection efficiency of the network device in detecting the second indication information and reducing the complexity of the network device.

[0177] In addition, in one embodiment, the network device can configure the UTO-UCI indication method for the terminal. Specifically, the UTO-UCI indication method includes: UTO-UCI can be used to indicate the occupancy of the CG transmission opportunity within a CG cycle period, or, it can be used to indicate the occupancy of the CG transmission opportunities within multiple CG cycle periods, or, UTO-UCI is not sent.

[0178] In one implementation, optionally, the terminal may send capability indication information to the network device to report the capabilities supported by the terminal to the network device. For example, the capability indication information is used to indicate whether the terminal supports configuring multiple CG transmission opportunities within a CG cycle. In addition, the capability indication information may also indicate whether the terminal supports indicating the occupancy of CG transmission opportunities by sending UTO-UCI. Thus, after receiving the capability indication information, the network device may configure CG resources for the terminal according to the capability indication information, and configure the indication method of UTO-UCI.

[0179] Among them, the CG resources configured by the network device for the terminal may include one CG transmission opportunity, or may include multiple CG transmission opportunities within a CG cycle period. It should be noted that the different types of CG resources configured by the above network device for the terminal and the indication method of the UTO-UCI configured by the network device for the terminal may be independent of each other, or the indication method of the UTO-UCI may depend on the type of CG resources configured by the network device for the terminal.

[0180] In a possible scenario one, the network device configures the terminal to include multiple CG transmission opportunities within a CG cycle period, but does not support UTO-UCI to indicate the occupancy of the CG transmission opportunities.

[0181] In another possible scenario two, the network device configures the terminal: a CG cycle period includes a CG transmission opportunity, and supports UTO-UCI to indicate the occupancy status of CG transmission opportunities in multiple CG cycle periods.

[0182] In another possible scenario three, the network device configures the terminal: a CG cycle period includes multiple CG transmission opportunities, and supports UTO-UCI to indicate the occupancy status of the CG transmission opportunities within a CG cycle period.

[0183] In another possible scenario four, the network device configures the terminal to include one CG transmission opportunity within one CG cycle period, but does not support UTO-UCI to indicate the occupancy of CG transmission opportunities within multiple CG cycle periods.

[0184] Based on the above scenario three, the present application also provides a communication method, which indicates the number of bits of UTO to the terminal through the network device, such as Fig.10 As shown, the method may include the following steps:

[0185] 1001: The network device sends second configuration information to the terminal.

[0186] Correspondingly, the terminal receives second configuration information from the network device.

[0187] Among them, the second configuration information is used to configure the number of bits P occupied by the third indication information, and the third indication information indicates the occupancy of the CG transmission opportunity within the CG cycle period. The minimum value of P is associated with the duration of the CG cycle period, and P is a positive integer.

[0188] That is, the network device may configure the number of bits occupied by the third indication information for the terminal as P, so that the terminal may determine the number of bits of the third indication information according to the number of bits P indicated in the second configuration information.

[0189] Optionally, the third indication information may be carried on UCI, which is UTO-UCI.

[0190] In one embodiment, the second configuration information is also used to configure at least N time units in the CG cycle period for the terminal, which are used to determine the time unit carrying the CG transmission opportunity. That is, when the network device configures CG resources for the terminal, it can carry the indication information of the number of bits occupied by the third indication information.

[0191] Alternatively, the method further includes: the network device sends first configuration information to the terminal, the first configuration information is used to configure the CG cycle period to include at least N time units, the N time units include time units corresponding to CG transmission opportunities, and N is a positive integer. In other words, the network device can send the first configuration information and the second configuration information to the terminal, respectively, to configure the CG resources and the number of bits occupied by the third indication information.

[0192] Optionally, the second configuration information may be carried in an RRC message. Exemplarily, the number of bits occupied by the third indication information may be represented by an RRC configuration parameter lengthofUTO_UCI.

[0193] In one implementation, P may be a positive integer, and the minimum value of P is at least N time units included in the CG cycle period configured by the network device for the terminal. If the CG cycle period configured by the network device for the terminal includes N time units for determining the CG transmission opportunity, that is, P may be set to any integer greater than or equal to N.

[0194] Specifically, if the network device sets the number of bits P occupied by the third indication information to N, that is, P=N, the specific indication method of the third indication information can refer to the aforementioned Fig. 9 The relevant description about the second indication information in the illustrated embodiment will not be repeated here.

[0195] In another embodiment, the minimum value of P is also associated with the uplink and downlink configuration of the TDD mode. For the TDD mode, different uplink and downlink configurations may have different numbers of CG transmission opportunities included in each corresponding CG cycle period. Therefore, the minimum value of P can be obtained based on the number of time units in the CG cycle period and the uplink and downlink configuration of the TDD mode.

[0196] Specifically, the minimum value of P may be L, where L = max{M 1 , M 2 , …M k , …, M K},M k It represents the number of CG transmission opportunities in CG cycle period k, where CG cycle period k is one of K CG cycle periods, and the value of k is {1, 2, …, K}, where K is a positive integer greater than 1.

[0197] The duration of the K CG cycle periods is also configured by the second configuration information, or may be configured by other configuration information sent by the network device. This application does not limit this.

[0198] Specifically, if the network device sets the number of bits P occupied by the third indication information to L, that is, P is set to the maximum value of the number of CG transmission opportunities in multiple CG cycle periods, the specific indication method of the third indication information can be referred to the aforementioned Figure 6 The relevant description about the first indication information in the illustrated embodiment will not be repeated here.

[0199] 1002: The terminal sends third indication information to the network device.

[0200] Correspondingly, the network device receives third indication information from the terminal.

[0201] Correspondingly, after obtaining the second configuration information, the terminal can determine that the number of bits occupied by the third indication information is P. The terminal can then determine the number of PUSCHs used in a CG cycle period according to the size of the data to be sent, that is, the occupancy of the CG transmission opportunity, thereby generating the corresponding third indication information.

[0202] Specifically, the terminal can generate a third indication information with a length of P bits according to the size of the data to be sent, which is used to indicate to the network device which CG transmission opportunities need to be occupied and which are not occupied within the CG cycle period. After the network device receives the third indication information, it can reallocate the unoccupied CG transmission opportunities, thereby reducing resource waste and improving resource utilization.

[0203] In the above-mentioned embodiment of the present application, the network device configures the indication length of the third indication information (such as UTO-UCI) for the terminal through a displayed indication method, so that the terminal can generate a third indication information of a fixed length according to the indication of the network device, which is used to indicate the occupancy of the CG transmission opportunity within the CG cycle period, thereby reducing the complexity of the network device's blind detection of the third indication information, that is, no matter how many valid CG transmission opportunities the third indication information is used to indicate, the length of the third indication information is fixed, and is a fixed length negotiated by the terminal and the network device, thereby improving the detection efficiency of the network device in detecting the third indication information and reducing the complexity of the network device.

[0204] In addition, the present application also provides a communication method, which is applied to the scenario where UTO-UCI indicates the occupancy of CG transmission opportunities corresponding to multiple CG cycle periods or business cycle periods, wherein the business cycle can specifically refer to the arrival period of business data. In other words, the information indicated by UTO-UCI is not limited to one CG cycle period or business cycle period, but can be indicated across CG cycle periods or business cycle periods.

[0205] Specifically, the information indication range of UTO-UCI is used to indicate the time domain range indicated by UTO-UCI (such as the unit can be a time slot), which means that the UTO-UCI can be used to indicate the occupancy of the CG transmission opportunity within the time domain range. In this application, UTO_P can be used to represent the information indication range corresponding to UTO-UCI. Among them, the information indication range corresponding to UTO-UCI can be the number of time units (such as time slots), and the indication range can include time units within one or more CG cycle periods, which is not limited in this application.

[0206] For example, Fig.11As shown in the figure, the CG period configured by the network device for the terminal includes 15 time slots, and the uplink and downlink configurations in the CG period are DDUDD. The terminal can send UTO-UCI to the network device at the corresponding CG transmission opportunity. Among them, the information indication range UTO_P corresponding to UTO-UCI is 15 time slots, which is determined by Fig.11 It can be seen that for the UTO-UCI-1 sent by the terminal, the information indication range of UTO-UCI-1 is: time slot 2 to time slot 16, which is used to indicate the occupancy of the CG transmission opportunity within the CG cycle period -1. For example, the bit information indicated by UTO-UCI-1 is (1, 1, 0), which can be used to indicate the occupancy of the three CG transmission opportunities within the CG cycle period -1, the first two are occupied, and the last one is not occupied.

[0207] As for UTO-UCI-2, the information indication range of UTO-UCI-1 is: time slot 7 to time slot 21, which can be used to indicate the occupancy of some CG transmission opportunities within CG cycle period-1, and to indicate the occupancy of some CG transmission opportunities within CG cycle period-2.

[0208] For example, the bit information indicated by UTO-UCI-2 is (1, 0, 1), which can be used to indicate that of the two CG transmission opportunities within CG cycle period -1, the first one is occupied and the second one is not occupied, and one CG transmission opportunity within CG cycle period -2 is occupied.

[0209] However, for XR services, data packets arrive periodically and the size of the data packets is variable. During the current CG cycle period or service cycle period, the terminal cannot accurately predict the size of the data packets arriving in the next CG cycle period or service cycle period. It is also impossible to determine the occupancy of the CG transmission opportunity in the next CG cycle period or service cycle period based on the size of the data packets. Therefore, if the above-mentioned implementation method is applied to the XR service, there may be a problem of inaccurate UTO-UCI indication.

[0210] Based on the above problems, the present application also provides an implementation method, which constrains the information indication range corresponding to the UTO-UCI so that the UTO-UCI only indicates the occupancy of the CG transmission opportunity within the current CG cycle period or the service cycle period, without indicating across cycles. This can improve the accuracy of the UTO-UCI indication, reduce the number of bits occupied by the UTO-UCI, and save signaling overhead.

[0211] Specifically, the method includes: the terminal sends a fourth indication information to the network device within the first cycle period, wherein the fourth indication information is used to indicate the occupancy of the CG transmission opportunity within the first cycle period. The first cycle period may be the first CG cycle period, or may be the first service cycle period, which is not limited in this application.

[0212] Optionally, the fourth indication information may be carried on UCI, which is UTO-UCI.

[0213] That is to say, for XR services, if the information indication range corresponding to the fourth indication information includes part of the second cycle period, the fourth indication information sent by the terminal may not include the bit used to indicate the occupancy of the CG transmission opportunity within the second cycle period, that is, the corresponding information indication range of the fourth indication information only includes the current cycle period. In other words, the number of UTO-UCI bits sent by the terminal in the current CG cycle period or service cycle period does not include the bit indicating the occupancy of the CG transmission opportunity corresponding to the next CG cycle period or service cycle period.

[0214] Specifically, in one implementation, if the number of bits occupied by the UTO-UCI initially set or configured by the terminal and the network device is the number of CG transmission opportunities, the number of bits occupied by the UTO-UCI actually sent by the terminal may be: L=L_1=L_U-L_2. Wherein, L_U is the number of CG transmission opportunities included in the information indication range corresponding to the UTO-UCI, L_1 is the number of CG transmission opportunities within the intersection of the first cycle period and the information indication range of the UTO-UCI, and L_2 is the number of CG transmission opportunities within the intersection of the information indication range of the UTO-UCI and the second cycle period.

[0215] Based on the aforementioned Fig.11 In the example shown, the bit information indicated by UTO-UCI-2 can be updated from (1, 0, 1) to (1, 0), and can be used to indicate that of the two CG transmission opportunities within CG cycle period -1, the first one is occupied and the second one is not occupied, instead of indicating the occupancy status of the CG transmission opportunity within CG cycle period -2, thereby saving the signaling overhead of UTO-UCI and improving the accuracy of the UTO-UCI indication.

[0216] For example, Fig.12As shown, the terminal includes a first cycle period and a second cycle period, and the service cycle of the terminal is 16.67 milliseconds, that is, the duration of the first cycle period and the second cycle period is 16.67 milliseconds. Among them, the UTO-UCI indication method initially agreed upon by the terminal and the network device can be: the current UTO-UCI is used to indicate the occupancy of the 6 CG transmission opportunities after the UTO-UCI, that is, the initial UTO-UCI can occupy 6 bits. Fig.12 As shown, the bit information of UTO-UCI-1 can be (1, 1, 1, 0, 0, 0). Through the above implementation of the present application, UTO-UCI can only indicate the dedicated situation of the CG transmission opportunity included in the current cycle period, and does not include the indication bit of the next cycle period. Therefore, the bit information of UTO-UCI-2 can be (1, 1, 0, 0), the bit information of UTO-UCI-3 can be (1, 0, 0), and the bit information of UTO-UCI-4 can be (0, 0).

[0217] Compared with the aforementioned implementation, if UTO-UCI-4 can be indicated across CG cycle periods or service cycle periods, that is, UTO-UCI-4 includes the occupancy of some CG transmission opportunities in the first cycle period and the second cycle period, then the bit information of UTO-UCI-4 can be (0, 0, 1, 1, 1, 1), or, it can be (0, 0, 0, 1, 1, 1). However, the indication of the second cycle period in the UTO-UCI-4 may be inaccurate, and the signaling overhead is also wasted. Through the above implementation of the present application, the bits occupied by UTO-UCI-4 are saved from 6 bits to 2 bits, which not only saves energy UTO-UCI signaling overhead, but also improves the indication accuracy of UTO-UCI.

[0218] It should be noted that the present application does not limit the specific indication method of UTO-UCI, and the UTO-UCI indication in the above embodiments is only used as an example to describe the implementation method provided by the present application.

[0219] The various embodiments mentioned above in this application can be combined without limitation if there is no contradiction between the solutions.

[0220] The above mainly introduces the scheme provided by the present application from the perspective of interaction between various network elements. Accordingly, the present application also provides a communication device, which can be a network device in the above method embodiment, or a component that can be used for a network device; or, the communication device can be a terminal in the above method embodiment, or a device including the above terminal, or a component that can be used for a terminal. It can be understood that in order to implement the above functions, the above network device or terminal, etc., includes a hardware structure and / or software module corresponding to each function. Those skilled in the art should easily realize that, in combination with the units and algorithm operations of each example described in the embodiments disclosed in this article, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the present application.

[0221] It should be understood that the above only describes the interaction between various network elements by taking the terminal and the network device as an example. In fact, the processing performed by the above terminal is not limited to being performed by only a single network element, and the processing performed by the above network device is not limited to being performed by only a single network element. For example, the processing performed by the network device can be performed by at least one of the CU, DU and RU respectively.

[0222] The present application can divide the functional modules of the network device or terminal according to the above method example. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated modules can be implemented in the form of hardware or in the form of software functional modules. It can be understood that the division of modules in the present application is schematic and is only a logical function division. There may be other division methods in actual implementation.

[0223] For example, when the functional modules are divided in an integrated manner, Fig.13 A schematic diagram of the structure of a communication device 1300 is shown. The communication device 1300 includes an interface module 1301 .

[0224] In some embodiments, the communication device 1300 may further include a storage module ( Fig.13 ), for storing program instructions and data.

[0225] Exemplarily, the communication device 1300 may be used to implement the functions of a terminal. Figure 6 The terminal described in the embodiment shown.

[0226] Among them, the interface module 1301 is used to receive the first configuration information from the network device, and the first configuration information is used to configure N time units within the authorized CG cycle period, wherein the N time units include the time units corresponding to the CG transmission timing.

The value of k is {1, 2, …, K}, where K is a positive integer greater than 1.

[0230] In addition, the communication device 1300 can also be used to implement, for example, Fig. 9 The terminal described in the embodiment shown.

[0235] The interface module 1301 is further configured to send third indication information to the network device.

[0236] In one implementation, the minimum value of P is also associated with a time division duplex (TDD) uplink and downlink configuration.
