[0027] The technical solution in this application will be described below with reference to the accompanying drawings.

[0028] Communication System

[0029] FIG1 illustrates a wireless communication system 100 used in an embodiment of the present application. The wireless communication system 100 may include communication devices. The communication devices may include a network device 110 and a terminal device 120. The network device 110 may be a device that communicates with the terminal device 120.

[0030] FIG1 exemplarily shows a network device and two terminals. Optionally, the wireless communication system 100 may include multiple network devices and each network device may include other numbers of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0031] Optionally, the wireless communication system 100 may further include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiment of the present application.

[0032] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: fifth generation (5G) system or new radio (NR), long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), etc. The technical solutions provided in this application can also be applied to future communication systems, such as the sixth generation mobile communication system, satellite communication system, etc.

The terminal device in the embodiments of the present application may refer to a device that provides voice and / or data connectivity to a user and can be used to connect people, objects and machines, such as a handheld device with wireless connection function, a vehicle-mounted device, etc. The terminal device in the embodiments of the present application can be a mobile phone, a tablet computer, a laptop computer, a PDA, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. Optionally, the UE can be used to act as a base station. For example, the UE can act as a scheduling entity that provides sidelink signals between UEs in vehicle-to-everything (V2X) or device-to-device (D2D). For example, a cellular phone and a car communicate with each other using sidelink signals. The cellular phone and smart home devices communicate without relaying the communication signal through a base station.

[0034] The network device in the embodiments of the present application may be a device for communicating with a terminal device. The network device may also include an access network device. The access network device may provide communication coverage for a specific geographical area and may communicate with the terminal device 120 located within the coverage area. The access network device may also be referred to as a radio access network device or a base station. The access network device in the embodiments of the present application may refer to a radio access network (RAN) node (or device) that connects the terminal device to a wireless network. Access network equipment can broadly cover various names as follows, or replace the following names, such as: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), master eNB (MeNB), secondary eNB (SeNB), multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. The base station can be a macro base station, a micro base station, a relay node, a donor node, or the like, or a combination thereof. A base station may also refer to a communication module, modem, or chip used to be set in the aforementioned device or apparatus. A base station may also be a mobile switching center and a device that performs base station functions in D2D, V2X, and machine-to-machine (M2M) communications, a network-side device in a 6G network, or a device that performs base station functions in future communication systems. A base station may support networks with the same or different access technologies. The embodiments of this application do not limit the specific technology and specific device form used by the access network device.

[0035] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move based on the location of the mobile base station. In other examples, a helicopter or drone can be configured to act as a device that communicates with another base station.

[0036] The communication equipment involved in a wireless communication system can include not only access network equipment and terminal equipment, but also core network (CN) network elements. Core network elements can be implemented by devices, that is, core network elements are core network devices. It is understood that core network devices can also be a type of network equipment.

[0037] The core network elements in the embodiments of the present application may include network elements that process and forward user signaling and data. For example, the core network equipment may include core network access and mobility management function (AMF), session management function (SMF), user plane gateway, location management function (LMF) and other core network equipment. Among them, the user plane gateway may be a server with functions such as mobility management, routing, and forwarding of user plane data, generally located on the network side, such as a serving gateway (SGW) or a packet data network gateway (PGW) or a user plane network element function entity (UPF). Of course, the core network may also include other network elements, which are not listed here one by one.

[0038] In some deployments, the network device in the embodiments of the present application may refer to a CU or a DU, or the network device may include a CU and a DU. The gNB may also include an AAU.

[0039] The network equipment and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; they can also be deployed in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the scenarios in which the network equipment and terminal devices are located.

[0040] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0041] Developed by the Third Generation Partnership Project (3GPP), 5G aims to meet people's demands for speed, latency, high-speed mobility, and energy efficiency, while adapting to the diversity and complexity of future services. Key 5G application scenarios include enhanced mobile broadband (eMBB), ultra-reliable and low latency communications (URLLC), and massive machine-type communications (mMTC).

[0042] eMBB aims to provide users with multimedia content, services, and data, and demand for it is growing rapidly. However, since eMBB can be deployed in diverse scenarios, such as indoors, in urban areas, and in rural areas, its capabilities and requirements vary significantly. Therefore, it cannot be generalized and requires detailed analysis based on specific deployment scenarios. Typical applications of URLLC include industrial automation, power automation, remote medical operations (surgery), and traffic safety. Typical characteristics of mMTC include high connection density, small data volumes, latency-insensitive services, low module costs, and long lifespans.

[0043] In some communication systems (such as NR systems), radio resource control (RRC) states may include RRC idle state (RRC_IDLE), RRC connected state (RRC_CONNECTED), and RRC inactive state (RRC_INACTIVE).

[0044] In RRC_IDLE mode, there is no RRC connection between the terminal device and the network device. The mobility of the terminal device is primarily reflected in the cell selection / reselection based on the terminal device. In RRC_IDLE mode, the core network (CN) initiates the paging process for the network device to the terminal device, and the paging area is configured by the CN. In addition, in RRC_IDLE mode, the network device does not have the terminal device's access stratum (AS) context.

[0045] In RRC_CONNECTED mode, an RRC connection exists between the terminal device and the network device. Both the network device and the terminal device store the terminal device's AS context. In RRC_CONNECTED mode, the network device only knows the terminal device's location at the cell level. In RRC_CONNECTED mode, unicast data can be transmitted between the terminal device and the network device, and the terminal device's mobility is managed and controlled by the network device.

[0046] RRC_INACTIVE is a new RRC state defined in some systems (such as NR systems). RRC_INACTIVE can reduce air interface signaling in the communication system. In addition, a terminal device in RRC_INACTIVE can quickly restore the wireless connection and quickly resume data services.

[0047] In RRC_INACTIVE mode, a CN-NR connection exists. The AS context of the terminal device is stored on a certain network device. In addition, in RRC_INACTIVE mode, the paging process of the network device to the terminal device can be triggered by the radio access network (RAN), and the RAN-based paging area can be managed by the RAN. In addition, in RRC_INACTIVE mode, the location of the terminal device that the network device can obtain is based on the RAN paging area level location, and the mobility of the terminal device is mainly reflected in the cell selection / reselection based on the terminal device.

[0048] XR

[0049] With the development of technology, research on XR / cloud gaming (CG) is becoming increasingly popular. Among them, XR technology mainly includes augmented reality (AR) technology, virtual reality (VR), etc. A major business of XR / CG is the video stream business. The arrival rate of the video stream can be measured by frames per second (fps). For example, the arrival rate of the video stream can be 30fps, 60fps, 90fps or 120fps, etc. Correspondingly, the period of the video stream can be 33.33ms, 16.67ms, 11.11ms or 8.33ms.

[0050] XR data features variable packet sizes and / or a large average packet size. For an AR / VR system with a 100Mbps data rate, for example, the average uplink packet size can be 20,833 bytes, with a maximum of 31,250 bytes and a minimum of 10,417 bytes. This means that within each cycle, for an AR / VR system with a 100Mbps data rate, the size of the packet to be transmitted ranges from [10,417 bytes to 31,250 bytes]. In a real-world system with a 100Mbps bandwidth, transmitting a 20,833-byte packet requires approximately four time slots of transmission resources.

[0051] In response to the above situation, the relevant technology supports configuring multiple physical uplink shared channel (PUSCH) occasions within a configured grant (CG) cycle for transmitting XR large data packets. In addition, XR large data packets can also be transmitted by configuring multiple sets of CG. When the amount of data transmitted in a certain data transmission is relatively small and does not need to occupy multiple pre-configured PUSCH occasions, the terminal device can notify the base station of the unused PUSCH occasions. The base station can reallocate unused PUSCH occasions to other terminal devices for data transmission, thereby improving system efficiency.

[0052] Application layer data exchanged between terminal devices and application servers or peer terminal devices, such as AR / VR / CG / live video, typically includes data streams in multiple modes, such as voice, video, text, and control information. These data streams usually require synchronization. For example, data such as voice, video, and subtitles need to be displayed to the user synchronously. The current practice for video playback is to synchronize multiple data streams through the application layer. For example, multiple received data streams are cached, and the corresponding data frames of multiple data streams are extracted based on the timestamps of the playback data streams and displayed synchronously to the user.

[0053] Typical XR frame rates supported by the technology are 15, 30, 45, 60, 72, 90, and 120 fps, corresponding to service periods of 66.66, 33.33, 22.22, 16.66, 13.88, 11.11, and 8.33 ms, respectively. In practice, many XR application implementations can adjust the bitrate / frame rate in response to changes in connection or channel quality.

[0054] In summary, XR service characteristics may include: non-integer XR traffic periodicity; variable XR data rate; quasi-periodic XR periodicity, hence enhancements would be beneficial in this area; and latency requirements, making it a latency-sensitive service.

[0055] As can be seen, some services experience changes in transmission rate (such as the frame rate or bit rate mentioned above). In this case, in related technologies, communication devices are unable to respond to rate changes in a timely manner, resulting in the communication devices being unable to respond to changes in connection quality, which in turn leads to a poor user experience.

[0056] FIG2 is a schematic flowchart of a wireless communication method provided in an embodiment of the present application.

[0057] Figure 2 can be performed by a first device and a second device. The first device may include the terminal device and the core network device described above. The second device may include the base station, the terminal device, and the core network device described above.

[0058] The method shown in FIG. 2 may include step S210 .

[0059] Step S210: The first device sends first information to the second device.

[0060] In some embodiments, when the first device includes a terminal device and the second device includes a base station, the terminal device may send first information to the base station. In some embodiments, when the first device includes a core network device and the second device includes a base station, the core network device may send first information to the base station. In some embodiments, when the first device includes a core network device and the second device includes a terminal device, the core network device may send first information to the terminal device. In some embodiments, when the first device includes a terminal device and the second device includes a core network device, the terminal device may send first information to the core network device. In some embodiments, when the core network device receives the first information sent by the terminal device, the core network device may also send the first information or a message generated based on the first information to the base station device.

[0061] The first information may be related to a transmission rate. In some embodiments, the transmission rate may be a rate adjusted by an application. The application may be an XR / CG application. In some embodiments, the transmission rate may be an arrival rate of a video stream. In some embodiments, the transmission rate may be a rate recommended or determined by the first device, a rate that needs to be modified or used, or a rate to be modified or used.

[0062] The information related to the transmission rate may include one or more of the following: historical information of the transmission rate, current information of the transmission rate, change information of the transmission rate, and initial information of the transmission rate.

[0063] The historical information of the transmission rate may include one or more of the following: the historically obtained transmission rate, the historically reported transmission rate. The current information of the transmission rate may include: the currently available transmission rate.

[0064] The transmission rate change information may reflect the change in the transmission rate and may include one or more of the following information: the change in the currently available transmission rate and the historically reported transmission rate, and the change in the currently available transmission rate and the historically acquired transmission rate.

[0065] The initial transmission rate information may be information about the available transmission rate first acquired by the first device, or the first available transmission rate acquired by the first device, or the default or predefined storage rate information, or the available transmission rate information acquired before the first device reports the first information. The current transmission rate information may be used to indicate the most recently acquired transmission rate by the first device, or the most recently available transmission rate.

[0066] Through the first information, the second device can obtain information related to the transmission rate. In some embodiments, when the first information includes information about changes in the transmission rate, the second device can directly obtain the adjustment status of the transmission rate through the information about changes in the transmission rate. In some embodiments, when the first information includes current information about the transmission rate, the second device can determine the adjustment status of the transmission rate by combining the currently received first information and the previously received first information. In some embodiments, when the first information includes initial information about the transmission rate and current information about the transmission rate, the second device can determine the adjustment status of the transmission rate based on the initial information and the current information.

[0067] In some embodiments, the transmission rate may include, but is not limited to, one or more of the following: bit rate, frame rate, packet size, packet rate, bandwidth, and transmission efficiency.

[0068] In some embodiments, the first information may indicate information related to a transmission rate. The information related to the transmission rate may include one or more of the following information: an adjustment status of the transmission rate, a current transmission rate, a historical transmission rate, a recommended or determined rate, a rate that needs to be modified or used, and a rate to be modified or used.

[0069] Exemplarily, the first information may include one or more of the following: a recommended or determined rate, a rate that needs to be modified or used, or a rate to be modified or used. The first information may be used to indicate one or more of the following: a rate required by the first device, a determined rate, or a modified rate result. As a recipient of the first information, the first information may be used to perform one or more of the following operations: obtaining the rate information, performing rate adjustment, or allocating or transmitting system resources.

[0070] It should be noted that, since the communication device can obtain the adjustment status of the transmission rate through the first information, in some embodiments, the first information can also be called rate adjustment information.

[0071] Optionally, in the case where the transmission rate changes regularly, the first information may indicate one or more of the following information about the transmission rate: usage time point, usage duration, usage sequence, usage pattern, usage pattern period, and usage pattern start time. Regular changes may include periodic changes, foreseeable changes, etc.

[0072] It should be noted that the transmission rate may include one or more of the following: the transmission rate for the terminal device, the transmission rate for one or more quality of service (QoS) flows, the transmission rate for one or more data flows, the transmission rate for one or more protocol data unit (PDU) sessions, and the transmission rate for one or more DRBs. In other words, the first information may be indicated at the granularity of one or more of the following: terminal device, QoS flow, data flow, PDU session, and DRB.

[0073] When certain information (including the first information and one or more of the second information, third information, etc. described later) is based on the granularity of the terminal device, the information may include the index of the terminal device and the corresponding information. When certain information is based on the granularity of QoS flow, the information may include the identifiers of one or more QoS flows and the corresponding information. In some embodiments, the identifiers of multiple QoS flows may form an identifier list, or the identifiers of the QoS flows may be represented in the form of a QoS flow bitmap. When certain information is based on the granularity of DRB, the information may include the identifiers of one or more DRBs and the corresponding information. In some embodiments, the identifiers of multiple DRBs may form an identifier list, or the identifiers of DRBs may be represented in the form of a DRB bitmap. When certain information is based on the granularity of data flow, the information may include the identifiers of one or more data flows and the corresponding information. In some embodiments, the identifiers of multiple data flows may form an identifier list, or the identifiers of data flows may be represented in the form of a data flow bitmap. When certain information is based on the granularity of PDU session, the information may include the identifiers of one or more PDU sessions and the corresponding information. In some embodiments, the identifiers of multiple PDU sessions may form an identifier list, or the identifiers of the PDU sessions may be represented in the form of a PDU session bitmap. It is understood that based on different granularities, information reporting or triggering at different angles or with different degrees of sophistication may be achieved.

[0074] In some embodiments, when the first information is related to the transmission rate of the terminal device, the first information may include an index of the terminal device and corresponding information related to the transmission rate. In some embodiments, when the first information is related to the transmission rate of one or more QoS streams, the first information may include identifiers of one or more QoS streams (in some embodiments, identifiers of multiple QoS streams may constitute an identifier list, or identifiers of QoS streams may be represented in the form of a QoS stream bitmap) and corresponding information related to the transmission rate. Wherein, multiple QoS streams may correspond one-to-one to information related to the transmission rate, or multiple QoS streams may correspond to information related to the transmission rate as a whole. In some embodiments, when the first information is related to the transmission rate of one or more DRBs, the first information may include identifiers of DRBs (for example, identifiers of multiple DRBs may constitute an identifier list, or identifiers of DRBs may be represented in the form of a DRB bitmap) and corresponding information related to the transmission rate. Wherein, multiple DRBs may correspond one-to-one to information related to the transmission rate, or multiple DRBs may correspond to information related to the transmission rate as a whole. In some embodiments, when the first information is related to the transmission rate of one or more PDU sessions, the first information may include the identifiers of one or more PDU sessions (in some embodiments, the identifiers of multiple PDU sessions may form an identifier list, or the identifiers of the PDU sessions may be expressed in the form of a PDU session bitmap) and the corresponding information related to the transmission rate. Among them, multiple PDU sessions may correspond one-to-one to the information related to the transmission rate, or multiple PDU sessions may correspond to the information related to the transmission rate as a whole. In some embodiments, when the first information is related to the transmission rate of one or more data streams, the first information may include the identifiers of one or more data streams (in some embodiments, the identifiers of multiple data streams may form an identifier list, or the identifiers of data streams may be expressed in the form of a data stream bitmap) and the corresponding information related to the transmission rate. Among them, multiple data streams may correspond one-to-one to the information related to the transmission rate, or multiple data streams may correspond to the information related to the transmission rate as a whole. It should be noted that in the present application, if the first information of one or some QoS flow granularity is reported, the first information of other QoS flow granularities may be reported or not. If the first information of one or more DRB granularities is reported, the first information of other DRB granularities may or may not be reported. If the first information of a certain granularity is reported, the first information of other types of granularities may or may not be reported. In some embodiments, if the first information of the terminal device granularity is reported, the first information of the QoS flow granularity and / or DRB granularity may or may not be reported.

[0075] In some embodiments, the first device may send second information to the second device. The second information may be used to indicate whether the first device supports reporting of the first information. In some embodiments, when the first device includes a terminal device and the second device includes a base station, the terminal device may send the second information to the base station to indicate whether the terminal device supports reporting of the first information. In some embodiments, when the first device includes a terminal device and the second device includes a core network device, the terminal device may send the second information to the core network device to indicate whether the terminal device supports reporting of the first information.

[0076] In the present application, the core network device may include at least one of the following: UPF, SMF, application function (AF), and policy control function (PCF).

[0078] In some embodiments, the second device may send a first request to the first device, where the first request may be used to request first information or enable the transmission of the first information. In response to the second device requesting the first information or enabling the transmission of the first information, the first device may send the first information to the second device. In other words, if the second device does not request the transmission of the first information, the first device may not send the first information to the second device; if the second device requests the transmission of the first information, the first device may send the first information to the second device.

[0079] It should be noted that the embodiments of the first device sending the first information provided in this application can be implemented in combination. In some embodiments, in response to the second device requesting the first information, if the first device obtains the first information, the first device can send the first information to the second device; in response to the second device requesting the first information, if the first information is available or valid, the first device can send the first information to the second device; in response to the second device requesting the first information, the first device can periodically send the first information to the second device; in response to the second device requesting the first information, if the first condition is met, the first device can send the first information to the second device.

That is, if the second device does not enable the first device to send the first information, the first device may not send the first information to the second device; if the second device enables the first device to send the first information, the first device may send the first information to the second device.

[0081] It should be noted that the embodiments of the first device sending the first information provided in this application can be implemented in combination.

[0082] In some embodiments, the second device may send third information to the first device. The third information may be used to trigger or enable the first device to send the first information. In other words, through the third information, the second device may instruct the first device to report the first information.

[0083] Exemplarily, the third information may be carried in an RRC message. In some embodiments, the third information may be carried in other configuration (otherconfig) information in the RRC message.

[0130] It should be noted that if the change between the required transmission rate corresponding to the first QoS flow and the historically required transmission rate is greater than or equal to the first threshold, and the change between the required transmission rate corresponding to the second QoS flow and the historically required transmission rate is not greater than or equal to the first threshold, then the first device may not send the first information corresponding to the second QoS flow, or the first device may report both the first information for the second QoS flow and the first information for the first QoS flow. In addition, if the change between the required transmission rate corresponding to the first DRB and the historically required transmission rate is greater than or equal to the first threshold, and the change between the required transmission rate corresponding to the second DRB and the historically required transmission rate is not greater than or equal to the first threshold, then the first device may not send the first information corresponding to the second DRB, or the first device may report both the first information for the second DRB and the first information for the first DRB. In addition, if the change between the required transmission rate corresponding to the first PDU session and the historically required transmission rate is greater than or equal to the first threshold, and the change between the required transmission rate corresponding to the second PDU session and the historically required transmission rate is not greater than or equal to the first threshold, the first device may not send the first information corresponding to the second PDU session, or the first device may report both the first information for the second PDU session and the first information for the first PDU session. In addition, if the change between the required transmission rate corresponding to the first data stream and the historically required transmission rate is greater than or equal to the first threshold, and the change between the required transmission rate corresponding to the second data stream and the historically required transmission rate is not greater than or equal to the first threshold, the first device may not send the first information corresponding to the second data stream, or the first device may report both the first information for the second data stream and the first information for the first data stream.

[0131] For ease of understanding, the first condition is explained below using Examples 1 to 6.

[0132] Example 1: For QoS flow 1 / DRB1, if the transmission rate is not reported, or the reporting prohibition timer is not running, or the reporting has changed, the first device can report the first information for QoS flow 1 / DRB1. If the reporting prohibition timer for QoS flow 2 / DRB2 has not timed out, or the first information for QoS flow 2 / DRB2 has not been reported, or the first information for QoS flow 2 / DRB2 has not changed, the first information for QoS flow 2 / DRB2 will not be reported.

[0133] Example 2: For QoS flow 1 / DRB1, if the transmission rate is not reported, or the reporting prohibition timer is not running, or the reporting has changed, then the information of QoS flow 1 / DRB1 + the information of QoS flow 2 / DRB2 can be reported, even if the reporting prohibition timer for QoS flow 2 / DRB2 has not timed out or the first information for QoS flow 2 / DRB2 has not been reported or the first information for QoS flow 2 / DRB2 has not changed.

[0134] Example 3: For QoS flow 1 / DRB1, if the transmission rate is not reported, or the prohibit reporting timer is not running, or there is a change in the report, the information of QoS flow 1 / DRB1 + the information of QoS flow 2 / DRB2 can be reported. At this time, the prohibit reporting timer for QoS flow 2 / DRB2 has timed out or the first information for QoS flow 2 / DRB2 has not been reported.

[0135] Example 4: For QoS flow 1, if the transmission rate is not reported, or the reporting prohibition timer is not running, or the reporting has changed, the first device can report the first information for QoS flow 1. If the reporting prohibition timer for QoS flow 2 has not timed out, or the first information for QoS flow 2 has not been reported, or the first information for QoS flow 2 has not changed, the first information for QoS flow 2 will not be reported.

[0136] Example 5: For QoS flow 1, if the transmission rate is not reported, or the prohibit reporting timer is not running, or the reporting has changed, the information of QoS flow 1 + the information of QoS flow 2 can be reported, even if the prohibit reporting timer for QoS flow 2 has not timed out or the first information for QoS flow 2 has not been reported or the first information for QoS flow 2 has not changed.

[0137] Example 6: For QoS flow 1, if the transmission rate is not reported, or the prohibit reporting timer is not running, or there is a change in the report, the information of QoS flow 1 + the information of QoS flow 2 can be reported. At this time, the prohibit reporting timer for QoS flow 2 has timed out or the first information for QoS flow 2 has not been reported.

[0138] The present application does not limit the manner in which the first device obtains the first information and / or the transmission rate. In some embodiments, the acquisition of the first information and / or the transmission rate may satisfy one or more of the following: interaction from the first protocol layer of the terminal device to the second protocol layer of the terminal device; acquisition through the implementation of the terminal device; acquisition through packet header information; acquisition through interactive information between the core network, and acquisition by the interaction between the application (application, APP) of the terminal device and the application server. Among them, the first protocol layer is higher than the second protocol layer. The first protocol layer may be, for example, a MAC layer, and the second protocol layer may be, for example, a PHY layer. The header information may include information contained in the header of a packet transmitted between different protocol layers, and / or information contained in the header of a packet transmitted between different devices.

[0139] In an optional embodiment, the first information may be carried in one or more of the following information: an RRC message, a non-access stratum (NAS) message, a media access control element (MAC CE), uplink control information (UCI), a physical uplink control channel (PUCCH), or a control plane (CP) message. Similarly, the second information or the third information may be carried in one or more of the following information: an RRC message, a NAS message, a MAC CE, UCI, PUCCH, or a control plane message.

[0140] Exemplarily, when the first device includes a terminal device and the second device includes a base station, the first information can be carried in an uplink RRC message. The uplink RRC message may include a terminal device assistance information (UEassistanceinformation) message. In some embodiments, uplink service information (UL-TrafficInfo) can carry the first information.

In some embodiments, new UAI reporting content can be introduced in UEassistanceinformation. In some embodiments, a new information element can be introduced to indicate the first information.

[0141] For example, if in a sidelink (SL) communication scenario, when the first device includes a terminal device and the second device includes a base station, the first information can be carried in sl-UE-AssistanceInformationNR or other newly added terminal device auxiliary information IE; and / or the second information can be carried in sl-AssistanceConfigNR.

[0142] Exemplarily, when the first device includes a terminal device and the second device includes a base station, the first information may be carried in an uplink NAS message. The uplink NAS message may include, for example, an uplink information transfer (UL information transfer) or other NAS messages.

[0143] Exemplarily, when the first device includes a core network device and the second device includes a base station, the first information can be carried in a control plane message. The control plane message may include, for example, time sensitive communication assistance information (TSCAI) and / or a time sensitive communication assistance container (TSCAC) message. Since TSCAI is based on QoS flow indication, the first information corresponding to the QoS flow corresponding to the TSCAI can be added to the TSCAI information.

[0158] The fourth information may be used to indicate one or more of the following: one or more transmission resource sets, one or more transmission parameter sets, one or more carriers or Scells (such as those that need to be activated or deactivated, or configured or deconfigured).

[0159] As described above, the first operation may include one or more of the following: selecting or recommending a target transmission resource set from one or more transmission resource sets; selecting or recommending a target transmission parameter set from one or more transmission parameter sets.

That is, the initial or default transmission resource set and / or the initial or default transmission parameter set may be indicated by the second device to the first device.

[0176] In some embodiments, the second device may send fifth information to the first device. The fifth information may be used to indicate a changed transmission parameter set or a target transmission parameter set; and / or, the fifth information may be used to indicate a changed transmission resource set or a target transmission resource set.

The changed transmission resource set may be the changed target transmission resource set. That is, if the transmission resource set selected or recommended by the second device is different from the currently used transmission resource set, the target transmission resource set may be the changed transmission resource set.

[0177] Exemplarily, after the second device selects or recommends a target transmission parameter set and / or a target transmission resource set, the second device may indicate to the first device the target transmission resource set and / or target transmission parameter set selected or recommended by the second device. Alternatively, after the second device selects or recommends a target transmission parameter set and / or a target transmission resource set, if the target transmission parameter set and / or the target transmission resource set is different from the currently used transmission parameter set and / or transmission resource set, the second device may indicate the changed transmission resource set and / or the changed transmission parameter set.

[0180] In some embodiments, the first device and / or the second device may perform transmission based on the fifth information. That is, the first device and / or the second device may perform transmission using the target transmission resource set and / or target transmission parameter set indicated by the fifth information. That is, the target transmission resource set and / or target transmission parameter set are the sets determined to be used.

[0181] In some embodiments, the first device and / or the second device may determine transmission parameters and / or transmission resources based on the fifth information. That is, the first device and / or the second device may determine appropriate transmission parameters and / or transmission resources based on the target transmission resource set and / or target transmission parameter set indicated by the fifth information before performing transmission. In other words, the target transmission resource set and / or target transmission parameter set are recommended sets.

That is, the first device and / or the second device may use the rate identifier or rate value indicated by the fifth information to determine a target transmission resource set and / or a target transmission parameter set for transmission. That is, the target transmission resource set and / or the target transmission parameter set are the sets determined to be used.

[0183] In some embodiments, if the first device determines or recommends transmission parameters and / or transmission resources based on the fifth information (i.e., the target transmission parameter set and / or target transmission resource set is a recommended set), the first device may send sixth information. The sixth information may be used to indicate the transmission parameters and / or transmission resources recommended or determined by the first device. In other words, the sixth information may be related to the fifth information. In some embodiments, the sixth information may be equal to the fifth information, or the sixth information may be similar to the fifth information.

[0184] In some embodiments, when the first device determines or recommends rate information (i.e., target rate information) based on the fifth information, the first device may send sixth information. The sixth information may be used to indicate the target rate information recommended or determined by the first device, and / or transmission parameters and / or transmission resources.

In some embodiments, the sixth information may be equal to the fifth information, or the sixth information may be similar to the fifth information.

[0185] In some embodiments, the first device may send seventh information to the second device. The seventh information may be used to indicate transmission parameters and / or transmission resources recommended or determined by the first device, and / or the first device may transmit based on the seventh information. It will be appreciated that in this embodiment, the first device may directly recommend or determine transmission parameters and / or transmission resources, eliminating the need to select from one or more sets.

The seventh information may be used to indicate rate information recommended or determined by the first device, and / or recommended transmission parameters and / or transmission resources, and / or the first device performs transmission based on the seventh information. It is understandable that in this embodiment, the first device may directly recommend or determine the rate, and / or transmission parameters and / or transmission resources, thereby eliminating the need to select from one or more sets. Optionally, the second device determines the transmission resources, transmission parameters, or transmission rate based on the recommended information, indicates the transmission resources, transmission parameters, or transmission rate ultimately used by the first device, and / or performs transmission or scheduling.

[0187] Optionally, the first device and / or the second device may use the transmission resources and / or transmission parameters indicated by the seventh information for transmission. Alternatively, the first device and / or the second device may not directly use the transmission resources and / or transmission parameters indicated by the seventh information for transmission. Whether to use the transmission resources and / or transmission parameters indicated by the seventh information for transmission may depend on network configuration or network changes.

[0188] In some embodiments, the second device may perform transmission based on the seventh information, or the second device may determine or recommend transmission parameters and / or transmission resources based on the seventh information. For example, when the second device determines or recommends transmission resources and / or transmission parameters based on the seventh information, the second device may send eighth information to the first device. The eighth information may be used to indicate the transmission parameters and / or transmission resources recommended or determined by the second device.

[0193] Step S310: The terminal device or the core network device indicates rate adjustment information to the base station.

[0194] In some embodiments, upon obtaining the rate adjustment information, the terminal device or the core network notifies the base station of the rate adjustment information. Alternatively, upon request from the base station for obtaining the rate adjustment information, the terminal device or the core network notifies the base station of the rate adjustment information.

[0195] In some embodiments, the terminal device may report to the base station whether the terminal device supports reporting of rate adjustment information.

[0196] In some embodiments, the terminal device obtains the rate adjustment information by: the upper layer of the terminal device interacts with the lower layer of the terminal device (implemented by the terminal device, or packet header information, etc.), or the core network notifies the terminal device (such as through NAS signaling).

[0197] In some embodiments, if the terminal device reports the rate adjustment information, the terminal device reports the rate adjustment information via a UL RRC message. In some embodiments, the UL RRC message may be a UEAssistanceInformation message. Alternatively, if the terminal device reports the rate adjustment information, the terminal device reports the rate adjustment information via a UL NAS message. In some embodiments, the UL NAS message may be a ULInformationTransfer message or other NAS message (after the core network obtains the rate adjustment information, it forwards the rate adjustment information to the base station).

[0198] In some embodiments, the base station may instruct the terminal device to report the rate adjustment information in otherconfig. The otherconfig may carry a first indication. In some embodiments, the first indication may instruct or enable the terminal device to report the rate adjustment information. In some embodiments, the first indication may indicate that the otherconfig may indicate a specific QoS flow index or QoS flow list to report the corresponding rate adjustment information. In some embodiments, the first indication may indicate that the otherconfig may indicate a specific DRB index or DEB list to report the corresponding rate adjustment information.

[0199] In some embodiments, the terminal device reports the rate adjustment information if a first condition is met. The first condition may include at least one of the following: a rate adjustment information reporting prohibition timer for the terminal device or for a QoS flow / DRB is not running or has timed out; the terminal device has not reported the rate adjustment information for the terminal device or for a QoS flow / DRB when reporting is configured; or there is a change in the last reported information or the intensity of the information change is greater than a first threshold (e.g., a change in the terminal device report, or a change in the report for a specific QoS flow / DRB).

[0200] In some embodiments, the indication granularity of the rate adjustment information is for terminal devices, for QoS flows, or for DRBs.

[0201] In some embodiments, the rate adjustment information may be added to the QOS-FlowUL-TrafficInfo IE of the PDU-SessionUL-TrafficInfo in the UL-TrafficInfo. In some embodiments, the rate adjustment information may be added to the UL-TrafficInfo. In some embodiments, the rate adjustment information may be added to the PDU-SessionUL-TrafficInfo in the UL-TrafficInfo. In some embodiments, the rate adjustment information corresponding to the QFI in the IE may be indicated in the above IE.

[0202] In some embodiments, a new UAI may be introduced in UEAssistanceInformation to report the rate adjustment information. For example, a new IE may be introduced. The new IE may be used to indicate rate adjustment information for a terminal device, a QoS flow, or a DRB.

[0203] If the CN indicates the rate adjustment information, the CN indicates the rate adjustment information through a CP message. In some embodiments, the CP message may be TSCAI. In some embodiments, since TSCAI is based on QoS flow indication, rate adjustment information corresponding to the QoS flow corresponding to the TSCAI may be added to the TSCAI information. In some embodiments, the rate adjustment information may also be indicated through other CP plane information, such as indicating one or more QoS flows, and indicating rate adjustment information for this QoS flow or for these QoS flows as a whole. In some embodiments, rate adjustment information for a terminal device may be indicated through CP information.

[0204] It should be noted that the rate adjustment information can be information for a terminal device, a QoS flow, or a QoS flow list. The rate adjustment information can be initial information or change information. The rate adjustment information can be bit rate information, frame rate information, or packet size / packet rate information.

[0205] Step S320: The base station performs related configuration, scheduling or resource allocation according to the rate adjustment information.

[0206] In some embodiments, based on the rate adjustment information, the base station schedules dynamic scheduling resources and, in some embodiments, adjusts the DG configuration. In some embodiments, for the updated DG configuration, the base station configures corresponding LCH configuration parameters and / or LCP mapping restrictions. The LCH configuration parameters and / or LCP mapping restrictions include at least some LCH parameters and / or LCP mapping restriction factors in the relevant protocol.

[0207] In some embodiments, based on the rate adjustment information, the base station may delete an existing CG or SPS configuration, or modify an existing CG or SPS configuration parameter, or add a new CG or SPS configuration. In some embodiments, for the updated CG / SPS configuration, the base station configures corresponding LCH configuration parameters and / or LCP mapping restrictions. The LCH configuration parameters and / or LCP mapping restrictions include at least some LCH parameters and / or LCP mapping restriction factors in the relevant protocol.

[0208] In some embodiments, based on the rate adjustment information, the base station adjusts the LCP mapping restrictions of the existing CG / SPS / DG.

[0209] In some embodiments, based on the rate adjustment information, the base station adjusts LCH configuration parameters of an existing LCH. In some embodiments, the LCH configuration parameters and / or LCP mapping restrictions include at least some LCH parameters and / or LCP mapping restriction factors in a related protocol.

[0210] It should be noted that, if it is a SL scenario, the terminal device can report the rate adjustment information of the SL UE's QoS flow to the base station. In some embodiments, the network can instruct the terminal device to report the rate adjustment information (for the terminal device or for the QoS flow) in the configuration sl-AssistanceConfigNR. The terminal device can use sl-UE-AssistanceInformationNR or add other terminal device auxiliary information IE to indicate the rate adjustment information.

[0211] Example 1 provides a method of indicating rate adjustment through the terminal device or CN. The rate adjustment information (i.e., rate change information) can assist the base station in performing resource or parameter configuration adjustment, quickly adapting to rate changes, and thus ensuring terminal device performance.

[0212] Example 2

[0213] Example 2 is directed to uplink transmission. In Example 2, the first device includes a terminal device or a core network device. The second device includes a base station. The first information is rate adjustment information. The base station preconfigures multiple sets of transmission resources and / or transmission configuration parameters. Based on the rate adjustment information indicated by the terminal device or the core network device, the base station may instruct the terminal device to use or change the transmission resources and / or transmission configuration parameters.

[0214] FIG4 is a schematic flowchart of a wireless communication method provided in Embodiment 2. The method shown in FIG4 may include steps S410 to S430.

[0215] Step S410: The terminal device or the core network indicates rate adjustment information to the base station.

[0216] The specific implementation of step S410 can refer to Example 1.

[0217] In step S420, the base station pre-configures multiple sets of transmission resources (ie, multiple transmission resource sets) and / or transmission configuration parameters (ie, multiple transmission parameter sets).

[0218] It should be noted that there is no restriction on the order of executing step S410 and step S420. Step S420 can be performed after step S410 or before step S410.

[0219] In some embodiments, the multiple sets of transmission resources and / or transmission configuration parameters correspond to different rates, or to different sets, wherein different sets correspond to different rates, or one set corresponds to one or more rates.

[0220] The multiple sets of transmission resources include at least one of the following: multiple sets of CG configurations, multiple sets of SPS configurations. In some embodiments, different configurations correspond to different configuration transmissions. In some embodiments, different configurations correspond to different sets or different configuration indexes.

[0221] The multiple sets of transmission configuration parameters include at least one of the following: at least one LCH configuration parameter, at least one PUSCH parameter, at least one PUCCH parameter, at least one PDSCH parameter, at least one PDCP parameter, at least one RLC parameter, and at least one MAC configuration parameter. In some embodiments, different parameters have different corresponding values. In some embodiments, different parameters correspond to different sets or set indexes.

[0222] The multiple sets of transmission resources and / or transmission configuration parameters include a default or initial resource or parameter. The default or initial resource or parameter is configured or indicated by RRC, or indicated by MAC CE, or indicated by DCI. The default or initial resource or parameter has a CG / SPS index of a specific value (such as minimum or maximum), or a specific set, or a set index of a specific value (such as minimum or maximum).

[0223] In some embodiments, when multiple sets of transmission resources and / or transmission configuration parameters are configured, the terminal device uses default or initial resources or parameters to perform transmission until the network instructs the terminal device to change the used resources or parameters.

[0224] In some embodiments, if the rate adjustment is periodic or regular, the base station can simultaneously indicate at least one of the usage time points, usage durations, usage orders, usage patterns, usage period of patterns, and usage start times of patterns of different sets in step S410.

[0225] In step S430, the base station indicates the resources or parameters to be changed or used through the indication information. Accordingly, the terminal device modifies, changes or uses the resources or parameters indicated by the base station for transmission based on the indication of the base station.

[0226] In some embodiments, the indication information may be indicated to the terminal device via DCI, MAC CE or RRC message.

[0227] In some embodiments, if the rate adjustment is periodic or regular, the base station may simultaneously indicate at least one of the following in step S410: the time point of use, duration of use, order of use, pattern of use, period of use of the pattern, and start time of use of the pattern for different sets. Accordingly, when the base station indicates a change, the base station may not indicate which set to use specifically, but may simply indicate a change in resource or parameter configuration.

[0228] In some embodiments, the base station may adjust the resources or transmission parameters required by the terminal device based on the rate adjustment information indicated by the terminal device or the CN. For example, the base station may instruct the terminal device to change or use a CG / SPS index, or a set to use, or indicate a set index to use. Accordingly, the terminal device performs transmission based on the base station's instruction using the updated resources and / or parameters.

[0229] In some embodiments, the base station schedules DG and / or removes / deactivates CG / SPS transmission based on rate adjustment information indicated by the terminal device or CN.

[0230] It should be noted that Example 2 can also be applied to SL scenarios.

[0231] Example 2 provides a method for obtaining the rate change information through a terminal device or CN indication method plus preconfigured resources. This method can quickly adjust resource usage based on the rate adjustment information, reduce air interface resource reconfiguration overhead, and quickly adapt to rate changes, ensuring terminal device performance.

[0232] Example 3

[0233] Example 3 is directed to uplink transmission. In Example 3, the second device may include a terminal device. The first device may include a core network device and / or a base station. The base station may pre-configure multiple sets of transmission resources and / or transmission configuration parameters. The terminal device may select to use or update transmission resources and / or transmission configuration parameters based on the rate adjustment information. Furthermore, the terminal device may notify the base station of the selected or updated transmission resources and / or transmission configuration parameters.

[0234] FIG5 is a schematic flowchart of a wireless communication method provided in Embodiment 3. The method shown in FIG5 may include steps S510 to S530.

[0235] Step S510: The base station pre-configures multiple sets of transmission resources and / or transmission configuration parameters.

[0236] The multiple sets of transmission resources and / or transmission configuration parameters correspond to different rates, or correspond to different sets (different sets correspond to different rates. Alternatively, one set corresponds to one or more rates).

[0237] The multiple sets of transmission resources include at least one of the following: multiple sets of CG configurations, multiple sets of SPS configurations. In some embodiments, different configurations correspond to different configuration transmissions. In some embodiments, different configurations correspond to different sets or different configuration indexes.

[0238] The multiple sets of transmission configuration parameters include at least one of the following: at least one LCH configuration parameter, at least one PUSCH parameter, at least one PUCCH parameter, at least one PDSCH parameter, at least one PDCP parameter, at least one RLC parameter, and at least one MAC configuration parameter. In some embodiments, different parameters have different corresponding values. In some embodiments, different parameters correspond to different sets or set indexes.

[0239] The multiple sets of transmission resources and / or transmission configuration parameters include a default (or initial) resource or parameter. The default (or initial) resource or parameter is configured or indicated by RRC, or indicated by MAC CE, or indicated by DCI. The default (or initial) resource or parameter may be a CG / SPS index with a specific value (such as minimum or maximum), or a specific set, or a set index with a specific value (such as minimum or maximum).

[0240] In some embodiments, when multiple sets of transmission resources and / or transmission configuration parameters are configured, the terminal device uses default (or initial) resources or parameters to perform transmission until the network instructs the terminal device to change the used resources or parameters.

[0241] The terminal device obtains the rate adjustment information. The terminal device obtains the rate adjustment information in the following ways: the upper layer of the terminal device interacts with the lower layer of the terminal device (implemented by the terminal device, or packet header information, etc.), or the CN notifies the terminal device (such as through NAS signaling).

[0242] The rate adjustment information may be information for a terminal device, a QoS flow, or a QoS flow list. The rate adjustment information may be initial information or change information. The rate adjustment information may be bitstream information, frame rate information, or packet size / packet rate information.

[0243] Step S520: The terminal device selects transmission resources or parameters to use or update.

[0244] In step S530, the terminal device notifies the base station of the selected or updated transmission resources and / or transmission configuration parameters, or the recommended configuration or parameters.

[0245] In some embodiments, the terminal device indicates to the base station the selected or updated transmission resources and / or transmission configuration parameters. In some embodiments, the indication can be implemented through UCI information, MAC CE, or RRC signaling. In some embodiments, the indication is for the terminal device, or for a QoS flow, or for a QoS flow list, or for a specific QoS flow, or for a resource, or for a collection.

[0246] Option 1: The terminal device adjusts the resources or transmission parameters it needs to use based on the rate adjustment information. For example, the adjustment may include: changing or using the CG / SPS index, determining the set to use, or the set index actually used. Accordingly, the terminal device uses the updated or adjusted resources or parameters for transmission.

[0247] Option 2, the terminal device determines the resources or transmission parameters it wants to use or update based on the rate adjustment information. For example, the resources or transmission parameters it wants to use or update include: the CG / SPS index changed or used by the terminal device, or the set determined to be used, or the set index actually used, etc. Accordingly, the terminal device reports the demand or recommends it to the network. The network determines or executes the adjustment of the resources or transmission to be used or updated based on the report of the terminal device. In some embodiments, the base station indicates the updated or used resources or parameters to the terminal device (such as through DCI, MAC CE, or RRC, etc.). In some embodiments, the base station schedules DG, and / or removes / deactivates CG / SPS transmission.

[0248] It should be noted that Example 3 can be applied to SL scenarios.

[0249] Example 3 provides a method of adjusting or recommending pre-configured resources through the terminal device. In Example 3, the terminal device can obtain the rate change information and quickly adjust resource usage based on the rate adjustment information, reducing the air interface resource reconfiguration overhead and quickly adapting to the rate change, thereby ensuring terminal device performance.
