Obviously, the described embodiments are some but not all of the embodiments of the application.

It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, not limited in number; for example, a first object can be one or more. Furthermore, in the specification and claims, "and" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0031] It is worth noting that the technologies described in this application are not limited to New Radio (NR) systems, Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in this application are often used interchangeably, and the described technologies can be used with the systems and radio technologies mentioned above, as well as with other systems and radio technologies. The following description describes NR systems for illustrative purposes, and NR terminology is used in most of the following description; however, these technologies can also be applied to applications other than NR systems, such as 6th generation (6G) wireless communication systems. th Generation 6G communication system.

[0032] To facilitate a better understanding of the embodiments of this application, the following technical points are introduced first:

[0033] I. Regarding XR services

[0034] XR refers to a technology that combines real and virtual environments with human-computer interaction devices. It is implemented using computer technology and wearable devices, where X represents a variable, which can be a current or future spatial computing technology. For example... Figure 1As shown, XR includes Augmented Reality (AR), Mixed Reality (MR), and Virtual Reality (VR), as well as areas in between. Compared with traditional video, VR brings an unprecedented immersive experience. AR is a technology that integrates real-world information and virtual-world information "seamlessly". MR is a combination of VR and AR, perfectly combining virtual reality and augmented reality to provide a new visualization environment. The significance of XR is the extension of human experience, especially in terms of presence (presented by virtual reality) and cognition (presented by augmented reality). With the continuous development of human-computer interaction technology, these meanings continue to evolve.

[0035] Referring to Figure 2 , XR services have high data rate, high reliability requirements, low latency requirements, non-integer periods, packet arrival time jitter, multiple service streams, and varying packet sizes, which pose higher requirements on mobile communication systems.

[0036] II. On multi-stream service transmission

[0037] To achieve immersive experience for users, multimedia services (such as XR) have multiple data stream transmissions. From the data type, it can be divided into video stream, audio stream, action transformation, and other control stream.

[0038] For video transmission, there are also full-view transmission, Field of View (FOV) transmission, and other transmission schemes. Among them, the full-view transmission scheme is to transmit 360° surround pictures to the terminal, and when the user's head turns and needs to switch pictures, all processing is completed locally on the terminal, which has very high transmission requirements. The FOV transmission scheme divides the 360° panoramic view into several view angles, generates a video file for each view angle, and only contains visual information within the view angle with high resolution and surrounding part with low resolution. The corresponding view angle file is transmitted to the user according to the user's view angle position, and there is multi-data stream transmission of FOV stream and non-FOV stream in this transmission scheme.

[0039] Since the data volume of the original video is quite large, video compression is also needed, that is, some redundancies in the original data are removed, and then transmission or storage is performed to reduce the demand for bandwidth and storage space. When video encoding is performed, three types of frames are generated, which are:

[0040] (1) I frame: Intra-coded frame, key frame, complete preservation of this frame picture; only the frame data is needed for decoding, and the amount of data information is relatively large.

[0041] (2) P frame: forward prediction encoding frame. P frame represents the difference between this frame and the previous key frame (or P frame), and when decoding, the final picture is generated by superimposing the previously cached picture and the difference defined by the current frame. The compression of P frame is relatively high, but it may cause the spread of decoding errors.

[0042] (3) B frame: bidirectional prediction interpolation encoding frame, which records the difference between the current frame and the previous and next frames. To decode the B frame, not only the previous cached picture is needed, but also the picture after decoding is needed. The final picture is obtained by superimposing the data of the previous and next pictures and the current frame. The compression ratio of B frame is the highest.

[0043] Therefore, in some multimedia services, multiple data streams will be transmitted simultaneously.

[0163] The first operation comprises one of the following:

[0164] (1) adjusting the HDRLL service according to the first information;

[0165] For example, the first communication device can perform adaptive adjustment according to the received first information (e.g., the first information represents actual reception of the radio access network device or a recommended value), and can adjust relevant parameters or directly adjust to a recommended parameter according to the first information.

[0166] (2) not adjusting the HDRLL service according to the first information;

[0167] For example, the first communication device can also not perform adjustment after analyzing system performance according to the first information, for example, it is found that the performance requirement has been met.

[0168] (3) ignoring the received first information.

[0169] Optionally, the above adjustment can comprise one or more of the following: (a) adjusting QoS, such as initiating a Qos modification process; (b) adjusting service characteristics of the HDRLL service.

[0170] Optionally, the service characteristics comprise one or more of the following:

[0172] (2) data volume ratio of different transmission units;

[0173] (3) service packet size of one or more transmission units;

[0174] (4) service packet size ratio of different transmission units;

[0180] (10) Transmission mode of the HDRLL service;

[0181] (11) Quantization parameter of the HDRLL service;

[0182] (12) Encoding mode of the HDRLL service.

[0183] For example, the code rate is increased or decreased, or the quantization parameter is increased or decreased, or the value of a is adjusted.

[0184] In an embodiment of the present application, step 501 comprises:

[0185] The first communication device receives the first information from the radio access network device through a first channel, and the first channel is a dedicated channel between the first communication device and the radio access network device.

[0186] In an embodiment of the present application, after step 501, the method further comprises:

[0187] The first communication device sends second information to the radio access network device, and the second information is used to assist the radio access network device to stop or suspend sending the first information.

[0188] It can be understood that, the first communication device sends the stop / suspend indication information as long as the first information is received (for example, the power configuration of the radio access network device or the capability information of the RAN is received, or the first communication device does not use the first information reported by the radio access network device); or the first communication device sends the stop / suspend indication information after judging according to the first information.

[0189] Optionally, the second information indicates that the first communication device has successfully received the first information.

[0190] Optionally, the second information can include first indication information, and the first indication information includes one or more of the following:

[0191] (1) A first timer, before the first timer expires, the radio access network device stops or suspends sending the first information to the first communication device;

[0192] (2) An indication bit;

[0193] (3) A reason value.

[0194] In another embodiment of the present application, after step 501, the method further comprises:

[0195] The first communication device receives first information from the radio access network device within a second time (or time window or timer), and sends second information to the radio access network device to assist the radio access network device to stop or suspend sending the first information, if a second condition is met;

[0196] Optionally, the second condition comprises one or more of the following:

[0197] (1) Within the second time, the transmission quality of the radio access network device is higher than a preset threshold value;

[0198] (2) Within the second time, the first information sent by the radio access network device does not change;

[0199] For example, the first information sent is always recommended left and right eye alternation transmission; or the first information sent is always recommended I frame and P frame traffic packet size ratio of 1.5 (the radio access network device always reports repeated information, which has no meaning, so the first communication device sends the second information to instruct the radio access network device to stop / suspend reporting).

[0200] (3) Within the second time, the first information sent by the radio access network device changes;

[0201] For example, the first information sent: the transmission error rate of I frame / P frame / B frame changes from 15% to 10% (indicating that the transmission quality of the radio access network device has improved); or the recommended I frame and P frame traffic packet size ratio changes from 1.5 to 3 (indicating that the carrying capacity of the radio access network device has increased at this time).

[0202] (4) Within the second time, the first information sent by the radio access network device is consistent with the behavior or configuration of the first communication device.

[0203] For example, the first information sent: the recommended quantization parameter for video encoding is 18, and the quantization parameter actually adopted by the first communication device is indeed 18. (For example, quantization parameter, ratio of different transmission unit quantities, generation method of HDRLL service, etc. The radio access network device does not know the configuration of the first communication device explicitly, and the value recommended by the radio access network device may be exactly the current configuration of the first communication device).

[0204] Optionally, the length of the second time is preconfigured by the first communication device, or is configured according to the local strategy of the first communication device.

[0205] The transmission delay or rebuffering time or duration or generation period or unit time or generation time or first timer or second time or generation time interval unit in this paper includes one of the following: seconds, milliseconds, frames, subframes, time slots, and symbols.

[0206] In the embodiments of the present application, the first communication device can adaptively adjust the service characteristics (such as video encoding mode, service generation / sending mode) or QoS of the HDR LL service according to the first information reported by the radio access network device, so as to help the radio access network device to better complete data transmission, thereby improving system performance and user experience.

[0207] The embodiments of the present application will be described below in combination with Embodiment One to Embodiment Seven.

[0208] Embodiment One: The first information includes the transmission situation of the radio access network device.

[0209] Method One: For downlink (DL) transmission, the radio access network device (such as the packet data convergence protocol (PDCP) / radio link layer control (RLC) layer of the base station (gNB)) reports the transmission unit error probability, or recommends to increase / decrease the error probability, or recommends to increase / decrease the error probability value to the first communication device. Then the first communication device adjusts the adaptive increase according to the information, for example, adjusts the service sending mode (such as adjusting the alternate sending of left eye and right eye service packets) or adjusts the video encoding mode / configuration (such as adjusting the data packet size ratio of I frame and P frame, the number ratio of I frame and P frame), etc., so as to reduce the PER of the RAN side and obtain better user experience. Or the first communication device changes the QoS according to the received information, triggers the QoS modification process, and selects a more suitable QoS for data transmission to improve user experience.

[0210] Method Two: The radio access network device maps the recommended increase / decrease error probability, or the recommended increase / decrease error probability value into a QoS adjustment request and sends it to the first communication device. The specific QoS adjustment request content includes but is not limited to one or more of the following: QFI value, 5QI value, priority.

[0211] Embodiment Two: The first information includes the data volume of the transmission unit or the service packet size

[0212] Reference is made to Figure 6, a Group of picture (GOP) contains 1 I frame and (K-1) P frames, the first information can be an average bit number, a minimum bit number, a maximum bit number of the I frame or the P frame, or an average packet size ratio of the I frame and the P frame. If an average packet size ratio of a current I frame and a P frame is α=3, the radio access network device finds that a service burst is too large at some time (for example, an I frame arrival time) and a PER is very high. The radio access network device can recommend down-regulating α or recommending using α=1.5 to the first communication device by using a channel of the radio access network device and the first communication device established in a Core Network (CN). The first communication device adjusts a video encoding mode according to the received first information, for example, uses α=1.5, thereby avoiding a very large data packet burst at a certain time, relieving scheduling and transmission pressure of the radio access network device, improving the PER on the RAN side, and obtaining better user experience.

[0213] Embodiment three: the first information includes a transmission mode of an HDR LL service.

[0214] If the current first communication device simultaneously transmits left and right eye data packets in the DL, the radio access network device finds that a service amount is too large at the same time and a timeout phenomenon is serious, see type 1 in Figure 7 The radio access network device can recommend using an alternate transmission mode of left and right eye service packets to the first communication device, see type 2 in Figure 7 .

[0215] The specific process is: a channel of the RAN and the first communication device is established in the CN, and the channel is used to carry the first information that is recommendation of alternate transmission of left and right eye service packets and a left and right eye time interval=6 ms. The first communication device adjusts a service generation mode according to the first information, and adjusts to alternate generation of left and right eye data and a left and right eye data generation interval=6 ms, thereby the radio access network device can use limited air interface resources to transmit service packets to users within a time delay requirement and provide better user experience. The first communication device can also not adjust if it considers that the recommended parameter of the radio access network device is unreasonable.

[0216] Embodiment four: the first information includes a ratio or corresponding relationship between different contents

[0217] For DL transmission, the radio access network device reports a recommended transmission unit transmission time delay and a ratio or corresponding relationship of different transmission unit data rates to the first communication device according to a current reception situation, and the first communication device adjusts the ratio of different transmission unit data rates according to a current time delay requirement to ensure system transmission quality.

[0218] For example, the first communication device assumes that the I-frame delay requirement of the wireless access network device is 20 ms, the average packet size ratio of the currently adopted I-frame and P-frame is a = 4. The recommended parameter reported by the wireless access network device is that the I-frame delay requirement = 10 ms corresponds to a = 1.5, and then the first communication device adjusts a = 3 according to the current I-frame delay requirement of 20 ms. If the first communication device considers that the recommended parameter of the wireless access network device is unreasonable, the first communication device can also not perform the adjustment.

[0219] Embodiment five: the first information is RAN configuration information.

[0220] The medium access layer (MAC) of the wireless access network device reports the current power-related configuration information (for example, the configuration information of CDRX (such as the DRX period and the starting position and the like), the CDRX configuration update information (such as the change of the DRX period from 10 ms to 16 ms), the wake-up signal (WUS) configuration information (such as the monitoring occasion, the monitoring period, and the monitoring duration of the WUS signal), the information of the PDCCH monitoring occasion, and the information of the PDCCH adaptive monitoring (such as the starting position / time of skipping the PDCCH monitoring and the duration of skipping the monitoring)) to the first communication device. Then, the first communication device adjusts the starting transmission time of the transmission unit according to the information, so as to match the power-related configuration of the wireless access network device, reduce the service packet waiting delay, and bring better user experience.

[0221] For example, referring to Figure 8a and Figure 8b , when the service packet sent by the first communication device arrives at the wireless access network device, the terminal is in the DRX_off state, and the wireless access network device can only perform the scheduling transmission of the service packet when the terminal is switched to the on duration state, thereby generating an additional waiting delay, which has a greater impact on the HDRLL service sensitive to the delay. The wireless access network device reports the configured CDRX starting offset, CDRX period, and duration to the first communication device, and the first communication device adjusts the generation time / generation period / sending time of the service, so that the service packet arrives at the wireless access network device at the on_duration state of the terminal or at the starting time of the on_duration, reduces the waiting delay of the service packet, brings better user experience, reduces user power consumption, for example, the service packet arrives at the wireless access network device at the starting time of the on_duration, the wireless access network device performs the scheduling transmission of the service packet, and the meaningless PDCCH monitoring of the terminal is reduced, thereby saving the power consumption.

[0222] Embodiment 6: Establishing a dedicated channel for AF and RAN device.

[0223] Referring to Figure 9 , subscription event and channel establishment are performed simultaneously

[0224] Step 1: AF sends a QoS flow modification message to a Policy Control Function (PCF). The QoS flow modification message contains an indication indicating that the PCF establishes a first channel.

[0225] Step 2: AF sends a request message to the PCF to subscribe to an XR-related event. The target address IP needs to be carried in the request message.

[0226] Step 3: The PCF derives QoS parameters according to the indication provided by the AF (and some other existing AF-provided parameters), generates first policy information (such as a Policy and Charging Control rule (PCC rule)), and sends it to a Session Management Function (SMF). Optionally, an indication information is also carried in the sent message. The indication information indicates that the first channel is used for event reporting, or indicates that the SMF establishes a channel for event reporting.

[0227] Step 4-1: The SMF derives a QoS profile according to the first policy information, and generates related information (such as tunnel info) of the first channel. At the same time, the SMF needs to carry an indication information indicating that the RAN does not need to establish a Data Radio Bearer (DRB) with the terminal, or indicating that the RAN establishes the first channel.

[0228] Step 4-2: The SMF sends the QoS profile, tunnel info and / or indication information to the RAN.

[0229] Step 4-3: According to the information provided in step 3-2, after the RAN successfully establishes the first channel, the RAN sends a confirmation message of the channel establishment completion to the SMF.

[0230] Step 5: The RAN reports at least one of the following through the first channel: a case of transmitting a high data rate low latency (HDR LL) service by the RAN device; information of one or more transmission units; information of the HDR LL service; a transmission condition of the RAN device; configuration information of the RAN device; and a QoS adjustment request (or described as a QoS adjustment indication).

[0231] Embodiment seven: Establishing a dedicated channel solution for AF and radio access network device

[0232] Referring to Figure 10 , the subscription event and the channel establishment are independent of each other, and subsequent association is performed.

[0233] Step 1-1: The radio access network device sends a request message for establishing a channel to the SMF. The request message carries an indication information indicating that the established channel is for event reporting.

[0234] Step 1-2: According to the indication information in step 1-1, the SMF generates the relevant information (tunnel info) of the first channel (the interaction process with other network elements is omitted here). At the same time, the SMF carries an indication information indicating that the radio access network device does not need to establish a DRB with the terminal, or indicating that the RAN establishes the first channel. The SMF sends the QoS profile, tunnel info and / or indication information to the radio access network device.

[0235] Step 1-3: According to the information provided in step 1-2, after the radio access network device successfully establishes the first channel, the radio access network device sends a confirmation message of the channel establishment completion to the SMF.

[0236] Step 2: The SMF sends the channel related information (such as at least one of the tunnel info, the terminal identifier (UE ID), the session identifier, and the channel identifier) to the AF (possibly forwarded by several network elements in the middle).

[0237] Step 3: The AF sends a request message to the PCF to subscribe to the XR related event. The request message needs to carry: target address IP, and the identification information obtained in step 2 (including: tunnel info, terminal identifier, session identifier, and / or channel identifier).

[0238] Step 4: The PCF sends the target address IP and the identification information obtained in step 2 to the SMF according to the subscription event.

[0239] Step 5: The SMF sends the target address IP and the identification information obtained in step 4 to the RAN. The role of this message is to make the radio access network device associate the AF (according to the target IP address) and the previously established channel (according to the identification information), or to activate the previously established channel.

[0240] Step 6: The radio access network device reports at least one of the following through the established channel: radio access network device side reception state information; number of different transmission units; transmission unit generation time related information; quantization parameter; service generation mode; QoS adjustment request.
