Technical Field

[0002] In related technologies, an extended reality (eXtended Reality, XR) service may require multiple data streams to work together, and these data streams are related. When the terminal transmits data to the base station, the base station needs to receive data from all relevant data streams of the current service in order to provide users with a good user experience.

[0091] Figure 1 A block diagram of a wireless communication system applicable to an embodiment of the present application is shown. The wireless communication system includes a terminal device 11 and a network side device (or network device) 12.

It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0092] In order to enable those skilled in the art to better understand the embodiments of the present application, the following description is first made.

[0093] (1) Basic concepts of XR;

[0094] The 3rd Generation Partnership Project (3GPP) 5G system introduced XR (eXtended Reality) services, which are divided into the following categories:

[0095] Augmented Reality (AR): seamless integration of the real world and the virtual world, half real and half fake;

[0096] Virtual Reality (VR): It uses devices to simulate a virtual world, which is completely fake.

[0097] Mixed Reality (MR): contains both real physical entities and virtual information.

[0098] XR services are modeled according to data frames. The same data frame can be divided into multiple Packet Data Unit (PDU) sets. The definition of PDU set is as follows: one or more PDUs corresponding to the same information unit constitute a PDU set. Only when all PDUs in a PDU set are successfully delivered, the PDUset is considered to be delivered successfully.

[0099] (2) Multimodal communication;

[0100] XR services can be applied to one or more user devices, such as 3D glasses, handle remote controls, etc. There are two basic ways for XR services to connect to wireless networks. One is that all user devices are connected to a terminal (UE) and XR services access the network through the terminal; the other is that different user devices access the network as different terminals. This way of XR services with different service flows coming from or going to different user devices is called multimodal communication.

[0101] Multimodal communication refers to the input or output coming from different modalities, such as:

[0102] video / audio media;

[0103] Information from environmental sensors, such as brightness, temperature, humidity, etc.;

[0104] Tactile data: includes perceptible sensations such as pressure, texture, vibration, temperature, or kinesthetic sensations such as gravity and tension. Position perception.

[0105] A notable feature of multimodal communication is the correlation between different data streams. Taking Table 1 as an example, for immersive multimodal VR applications, the delay between different media units is crucial, otherwise the user experience will be reduced. The time difference threshold between different modes may even be lower than the delay indicator of a single application. Taking the first row "audio-tactile" as an example, if touch precedes hearing, the delay threshold of hearing relative to touch is 50ms; if hearing precedes touch, the delay threshold of touch relative to hearing is 25ms. When the relative delay of the two service streams is greater than the threshold value, the immersive service experienced by the user will experience delays, stagnation and other unpleasant feelings.

[0106] Therefore, compared with traditional unimodal communication, multimodal communication also needs to pay more attention to the transmission time difference of related data streams, which cannot exceed the threshold requirement.

[0107] Table 1

[0108]

[0109] The services of related media units in multimodal communication are expressed as different service flows in the wireless network, which can be expressed as IP flows, and then mapped to QoS flows that need to be transmitted in the access network. We call two or more flows with delay requirements between each other related flows. Ensuring the timely transmission of related flows specifically means that the transmission time difference of related flow data is lower than the threshold requirement.

[0110] The related streams may be multiple streams transmitted at one terminal or multiple streams transmitted at different terminals.

[0111] (3) Logical Channel Prioritization (LCP);

[0112] LCP can reflect the priority order of multiple logical channels (Logical Channel, LCH) when transmitting data. Each time a new transmission is performed, the terminal needs to organize the uplink data according to the logical channel priority process.

[0113] The Radio Resource Control (RRC) Information Element (IE) includes an IE named Logical Channel Config, which is used to configure the parameters of the logical channel.

[0114] RRC controls the transmission of uplink data on each logical channel of each Media Access Control (MAC) entity through signaling:

[0115] priority: This parameter is the priority value. A higher priority value indicates a lower priority of the current logical channel. It is an integer value between 1 and 16.

[0116] prioritizedBitRate: This parameter indicates the prioritized bit rate (PBR) of the logical channel;

[0117] bucketSizeDuration: This parameter indicates the maximum coefficient (BucketSize Duration, BSD) that the data of the logical channel can reach.

[0118] Each logical channel is assigned a priority, and the logical channels provide services in order of their priority. The data of the logical channel with the highest priority will be included in the MAC PDU first, followed by the data of the logical channel with the second highest priority, and so on, until the allocated resources are fully occupied or there is no more data to be sent.

[0119] In order to avoid the situation where higher priority logical channels always occupy resources, NR introduces the concepts of PBR and BSD. If the token bucket depth of the current logical channel grows to PBR*BSD, the data to be transmitted cannot continue to grow, and a minimum data rate guarantee is provided for each logical channel, thereby ensuring the service quality (Quality of Service, QoS) of other low priority logical channels.

[0120] The terminal maintains a variable B for each logical channel j j , which indicates the number of tokens currently available in the token bucket, and each token corresponds to 1 Byte of data. j It is initialized to 0 when the logical channel is established. Before each logical channel priority processing process, B j Increase PBR*T, where T represents the last B j The time after the growth moment. If B j >Token bucket size (PBR*BSD), then B j Set to the token bucket size.

[0121] The steps for allocating logical channel resources are as follows:

[0122] Step 1: For all B j Logical channels with priority > 0 are sorted in descending order.

[0123] Step 2: B jSubtract the size of all MAC Service Data Units (SDUs) of the MAC PDUs used by logical channel j in step 1.

[0124] Step 3: If there are still uplink resources left after the first two steps, the remaining resources are allocated to each logical channel according to the logical channel priority without comparing B. j The low-priority logical channels can only be served when all the data of the high-priority logical channels have been sent and the uplink grant has not been exhausted.

[0125] When a terminal performs multi-modal communication, logical channels are often correlated, that is, the transmission time difference between two or more LCHs should not be too large, otherwise the service will be affected.

[0126] like Figure 2 As shown, the embodiment of the present application also provides a method for adjusting the priority of a logical channel, which is executed by a terminal, and the method includes:

[0127] Step 201: When a trigger condition is met, adjust the priority of at least one logical channel among multiple logical channels;

[0128] Among them, the data of the multiple logical channels correspond to the same service, the multiple logical channels include a first logical channel and at least one second logical channel, and the priority of the second logical channel is not higher than the priority of the first logical channel; after adjusting the priority of the at least one logical channel, the difference between the sending time of the data of the first logical channel and the sending time of the data of the second logical channel is less than a first preset threshold.

[0129] Optionally, the data of the above multiple logical channels correspond to the same XR service.

[0130] Optionally, the difference between the sending time of the data of the first logical channel and the sending time of the data of the second logical channel is less than the first preset threshold, which can be understood as the difference between the start sending time of the data of the first logical channel and the start sending time of the data of the second logical channel is less than the first preset threshold, or the difference between the end sending time of the data of the first logical channel and the end sending time of the data of the second logical channel is less than the first preset threshold.

[0131] Optionally, the first preset threshold is notified by the core network, or notified by the application layer, or configured by the base station.

[0132] In an embodiment of the present application, when the trigger conditions are met, the priority of at least one logical channel among multiple logical channels corresponding to the same service is adjusted to ensure that the difference between the sending time of data of the first logical channel among the multiple logical channels and the sending time of data of the second logical channel is less than a first preset threshold, thereby effectively ensuring the service quality.

[0133] Optionally, the trigger condition includes at least one of the following:

[0134] The data of the first logical channel has been transmitted;

[0135] The waiting time of the data of the second logical channel in the buffer is greater than or equal to a second preset threshold;

[0136] A difference between a waiting time of data of the first logical channel in the buffer and a waiting time of data of the second logical channel in the buffer is greater than or equal to a third preset threshold;

[0137] A waiting time of a first packet data unit set PDU set of data of the second logical channel in the buffer is greater than or equal to a fourth preset threshold;

[0138] A difference between the priority of the first logical channel and the priority of the second logical channel is greater than a fifth preset threshold;

[0139] The priority of the first logical channel is increased;

[0140] A PDU set delay budget (PSDB) of the second logical channel is less than or equal to a sixth preset threshold;

[0141] A difference between the PSDB of the first logical channel and the PSDB of the second logical channel is greater than or equal to a seventh preset threshold.

[0142] Optionally, when a trigger condition is met, adjusting the priority of at least one logical channel among the multiple logical channels includes at least one of the following:

[0143] using the priority of the first logical channel as the priority of each of the second logical channels;

[0144] Taking a weighted average of the priorities of the plurality of logical channels as the priority of each logical channel in the at least one logical channel;

[0145] Assign a priority to each logical channel in the at least one logical channel in descending order of priority; for example, the value of priority is an integer value in the range of 1 to 16, and the number of the multiple logical channels is 5, then the priority values ​​corresponding to each logical channel are 1, 2, 3, 4, and 5 respectively;

[0146] Raising the priority of each logical channel in the at least one logical channel to the highest priority, for example, the priority value of each logical channel is 1;

[0147] Raising the priority of the second logical channel to the highest priority;

[0148] Adjusting the priority of the first logical channel and / or the second logical channel to a target priority, where the target priority is higher than the priority of a media access control MAC control element CE;

[0149] Optionally, the method of the embodiment of the present application further includes:

[0150] Determine the effective duration of the adjusted priority level of the at least one logical channel according to at least one of the following:

[0151] an eighth preset threshold, where the eighth preset threshold is a preset threshold corresponding to a waiting delay of data in the at least one logical channel;

[0152] The PSDB of the first logical channel;

[0153] PSDB for the second logical channel.

[0154] Here, the adjusted priority of at least one logical channel is valid within the above-mentioned valid time period. After exceeding the valid time period, the priority of at least one logical channel is restored to the priority before adjustment.

[0155] It should be noted that the second preset threshold to the eighth preset threshold in the embodiment of the present application can be notified by the core network, or notified by the application layer, or configured by the base station.

[0156] The following describes the method for adjusting the logical channel priority of the present application in conjunction with an embodiment.

[0157] Embodiment 1:

[0158] Taking two logical channels as an example, when data of the first logical channel LCH1 is transmitted, the terminal increases the priority of the second logical channel LCH2.

[0159] The logical channel identifier of LCH1 is LCID1, and the logical channel identifier of LCH2 is LCID2. The priority of the logical channel is processed internally by the terminal, and the terminal itself grasps the correlation between the first logical channel and the second logical channel.

[0160] Step 1: The terminal maintains a variable B for each logical channel j j , for all B j Logical channels with priority > 0 are sorted in descending order.

[0161] Step 2: Since the logical channel priority of LCH1 is the highest, the data in this channel will be transmitted first.

[0162] Step 3: The terminal searches for a second logical channel LCH2 related to the first logical channel LCH1.

[0163] Specifically, the terminal searches for a second logical channel related to data transmitted through the first logical channel. The data transmitted through the second logical channel and the data transmitted through the first logical channel correspond to the same XR service.

[0164] Step 4-1: Increase the priority of the second logical channel accordingly. Specifically, reduce the parameter value of the priority field in the information unit LogicalChannelConfig of LCH2 to the parameter value of the priority field in the information unit LogicalChannelConfig of LCH1. For example, reducing the priority value to "1" means that the data stream of LCH2 has the highest priority, and the terminal will first send the data streams in LCH1 and LCH2 in subsequent transmissions.

[0165] Step 4-2: Increase the priority of the second logical channel accordingly. Specifically, reduce the parameter value of the priority field in the information unit LogicalChannelConfig of LCH2. For example, adjust the priority value to "2", which is increased relative to LCH1. The data flow priority of LCH2 is second only to the data flow priority of LCH1. After the terminal allocates sufficient uplink resources for the data flow in LCH1, that is, B LCH1 After subtracting the size of all MAC SDUs of the MAC PDU used by the logical channel LCH1 in step 2, the remaining resources are first selected to be allocated to LCH2.

[0166] Wherein, step 4-1 and step 4-2 represent two methods under the same embodiment.

[0167] Embodiment 2:

[0168] Taking two logical channels as an example, when the PSDB parameter difference between the PDU sets of the first logical channel LCH1 and the second logical channel LCH2 is greater than the time difference threshold T (ie, the seventh preset threshold), the terminal will increase the priority of the LCH with the lower PSDB parameter value.

[0169] The logical channel identifier of LCH1 is LCID1, and the logical channel identifier of LCH2 is LCID2. The value of the time difference threshold T refers to the transmission time difference of the multi-modal communication related data stream, that is, the threshold value in Table 1.

[0170] Step 1: In this embodiment, it is assumed that the data stream in the first logical channel LCH1 arrives at the terminal buffer first, and the related data stream in the second logical channel LCH2 arrives at the terminal buffer later, and the PSDB parameter value of the PDU set in LCH1 is smaller than the PSDB parameter value of the PDU set in LCH2.

[0171] Step 2: The terminal reads the PSDB parameter values ​​of the PDU sets in the first logical channel and the second logical channel.

[0172] Step 3: After the terminal reads the two PSDB parameters, it calculates the PSDB parameter difference.

[0173] Step 4-1: Compare the PSDB parameter difference with the time difference threshold T. If the PSDB parameter difference exceeds the time difference threshold T, the terminal needs to reduce the difference of the PSDB parameter. Specifically, reduce the parameter value of the priority field in the information unit LogicalChannelConfig of LCH1 and LCH2. For example, reducing the priority value to "1" means that the data streams of LCH1 and LCH2 have the highest priority, and the terminal will first send the data streams in LCH1 and LCH2 in subsequent transmissions.

[0174] Step 4-2: Compare the PSDB parameter difference with the time difference threshold T. If the PSDB parameter difference exceeds the time difference threshold T, the terminal needs to reduce the difference in the PSDB parameters. Specifically, adjust the parameter values ​​of the priority field in the information unit LogicalChannelConfig of LCH1 and LCH2 to a weighted average. For example, adjusting the priority values ​​to the average of the priority values ​​of LCH1 and LCH2 means that the data streams of LCH1 and LCH2 have the same priority, and the terminal will subsequently transmit the data streams of LCH1 and LCH2 simultaneously to ensure a lower waiting delay.

[0175] Wherein, step 4-1 and step 4-2 represent two methods under the same embodiment.

[0176] Embodiment three:

[0177] Taking two logical channels as an example, when the priority of the first logical channel LCH1 is increased, the priority of the second logical channel LCH2 also needs to be increased accordingly.

[0178] The logical channel identifier of LCH1 is LCID1, and the logical channel identifier of LCH2 is LCID2. LCH1 has a higher priority than LCH2.

[0179] Step 1: Assuming that the data stream in the first logical channel LCH1 and the data stream in the second logical channel LCH2 both arrive in the buffer of the terminal, the terminal receives the downlink signaling sent by the base station, and needs to increase the priority of the first logical channel LCH1. Specifically, reduce the parameter value of the priority field in the information unit LogicalChannelConfig of LCH1. For example, reduce the priority value to "n". The terminal will give priority to sending the data stream in LCH1 in subsequent transmissions than in the original situation.

[0180] Step 2: The terminal searches for a second logical channel LCH2 related to the first logical channel LCH1.

[0181] Step 3-1: Increase the priority of the second logical channel accordingly. Specifically, reduce the parameter value of the priority field in the information unit LogicalChannelConfig of LCH2. For example, reduce the priority value to "n+1", which means that the data stream priority of LCH2 is second only to the data stream priority of LCH1. After allocating sufficient uplink resources to the data stream in LCH1, the terminal will first choose to allocate the remaining resources to LCH2.

[0182] Step 3-2: Increase the priority of the second logical channel accordingly. Specifically, reduce the parameter value of the priority field in the information unit LogicalChannelConfig of LCH2. For example, reduce the priority value to "n", which means that the data stream priority of LCH2 is equal to the priority of LCH1. The terminal will subsequently transmit the data streams of LCH1 and LCH2 at the same time to ensure a lower waiting delay.

[0183] Wherein, step 3-1 and step 3-2 represent two methods under the same embodiment.

[0184] Embodiment 4:

[0185] Taking two logical channels as an example, when the difference in waiting time between the data streams related to the first logical channel LCH1 and the second logical channel LCH2 is greater than the time difference threshold T (ie, the third preset threshold mentioned above), the terminal will increase the priority of the LCH with a longer waiting time.

[0186] The logical channel identifier of LCH1 is LCID1, and the logical channel identifier of LCH2 is LCID2. Each logical channel is provided with a timer. When data arrives in the logical channel, the timer is started / restarted to record the waiting time for the data.

[0187] The value of the time difference threshold T refers to the transmission time difference of the multimodal communication related data stream, that is, the threshold value in Table 1.

[0188] The embodiment specifically includes: Step 1: Assume that the data stream in the first logical channel LCH1 arrives at the terminal buffer first, and the related data stream in the second logical channel LCH2 arrives at the terminal buffer later, and the timers for recording data waiting time of each logical channel have started timing. The timer value of LCH2 is smaller than that of LCH1.

[0189] Step 2: The terminal reads the timer values ​​of the first logical channel LCH1 and the second logical channel LCH2.

[0190] Step 3: After the terminal reads the two timer values, it calculates the waiting time difference between the data streams of LCH1 and LCH2.

[0191] Step 4-1: Compare the waiting time difference with the time difference threshold T. If the waiting time difference exceeds the time difference threshold T, the terminal needs to increase the priority of the LCH with a larger timer value, that is, LCH1 with a longer waiting time. Specifically, reduce the parameter value of the priority field in the information unit LogicalChannelConfig of LCH1. For example, reducing the priority value to "1" means that the data stream of LCH1 has the highest priority, and the terminal will first send the data stream in LCH1 in subsequent transmissions.

[0192] Step 4-2: Compare the waiting time difference with the time difference threshold T. If the waiting time difference exceeds the time difference threshold T, the terminal needs to increase the priority of the LCH with a larger timer value, that is, LCH1 with a longer waiting time. Specifically, the parameter values ​​of the priority field in the information unit LogicalChannelConfig of LCH1 and LCH2 are adjusted to a weighted average. For example, the priority values ​​are adjusted to the average of the priority values ​​of LCH1 and LCH2, which means that the data streams of LCH1 and LCH2 have the same priority, and the terminal will send the data streams in LCH1 and LCH2 with a shorter time difference in subsequent transmissions.

[0193] Wherein, step 4-1 and step 4-2 represent two methods under the same embodiment.

[0194] Embodiment five:

[0195] Taking two logical channels as an example, when the waiting time of the first logical channel LCH1 in the buffer exceeds the preset delay threshold T', the terminal will increase the priority of the first logical channel LCH1 and the second logical channel LCH2.

[0196] The logical channel identifier of LCH1 is LCID1, and the logical channel identifier of LCH2 is LCID2. Each logical channel is provided with a timer. When data arrives in the logical channel, the timer is started / restarted to record the waiting time for the data.

[0197] The value of the preset delay threshold T' refers to the transmission waiting time threshold of each data stream of the multi-modal communication.

[0198] Step 1: Assume that the data stream in the first logical channel LCH1 arrives at the terminal buffer first, and the related data stream in the second logical channel LCH2 arrives at the terminal buffer later, and the timers for recording the data waiting time of each logical channel have started timing. The timer value of LCH1 is larger than that of LCH2.

[0199] Step 2: The terminal monitors the value of each logical channel timer in real time. When the value of the LCH1 timer exceeds the preset delay threshold T', it indicates that the waiting time of LCH1 in the buffer buffer exceeds the preset delay threshold. The terminal needs to increase the priority of LCH1, which is specifically manifested by reducing the parameter value of the priority field in the information unit LogicalChannelConfig of LCH1. For example, reducing the priority value to "1" means that the data stream of LCH1 has the highest priority, and the terminal will first send the data stream in LCH1 in subsequent transmissions.

[0200] Step 3: The terminal searches for a second logical channel LCH2 related to the first logical channel LCH1.

[0201] Step 4-1: Increase the priority of the second logical channel accordingly. Specifically, reduce the parameter value of the priority field in the information unit LogicalChannelConfig of LCH2. For example, reducing the priority value to "1" is equivalent to LCH1, which means that the terminal will subsequently transmit the data streams of LCH1 and LCH2 simultaneously.

[0202] Step 4-2: Increase the priority of the second logical channel accordingly. Specifically, reduce the parameter value of the priority field in the information unit LogicalChannelConfig of LCH2. For example, adjust the priority value to "2", which is incremented relative to LCH1. The data stream priority of LCH2 is second only to the data stream priority of LCH1. After allocating sufficient uplink resources for the data stream in LCH1, the terminal will first choose to allocate the remaining resources to LCH2.

[0203] Wherein, step 4-1 and step 4-2 represent two methods under the same embodiment.

[0204] Embodiment six:

[0205] Taking two logical channels as an example, when the waiting time of the first PDU set of the first logical channel LCH1 in the buffer exceeds the preset delay threshold T', the terminal will increase the priority of the first logical channel LCH1 and the second logical channel LCH2.

[0206] The logical channel identifier of LCH1 is LCID1, and the logical channel identifier of LCH2 is LCID2. Each logical channel is equipped with a timer. When the data of the first PDU set arrives in the logical channel, the timer is automatically started / restarted to record the waiting time of the first PDU set.

[0207] The value of the preset delay threshold T' refers to the transmission time delay threshold of each data stream of the multi-modal communication, that is, the value in Table 1.

[0208] Step 1: Assume that the data stream in the first logical channel LCH1 arrives at the terminal buffer first, and the related data stream in the second logical channel LCH2 arrives at the terminal buffer later, and the timers for recording the waiting time of the first PDU set in each logical channel have started timing. The timer value of LCH1 is relatively larger.

[0209] Step 2: The terminal monitors the value of each logical channel timer in real time. When the value of the LCH1 timer exceeds the preset delay threshold T', it indicates that the waiting time for the first PDU set of LCH1 in the buffer buffer exceeds the preset delay threshold. The terminal needs to increase the priority of LCH1, which is specifically manifested by reducing the parameter value of the priority field in the information unit LogicalChannelConfig of LCH1. For example, reducing the priority value to "1" means that the data stream of LCH1 has the highest priority, and the terminal will first send the data stream in LCH1 in subsequent transmissions.

[0210] Step 3: The terminal searches for a second logical channel LCH2 related to the first logical channel LCH1.

[0211] Step 4-1: Increase the priority of the second logical channel LCH2 accordingly. Specifically, reduce the parameter value of the priority field in the information unit LogicalChannelConfig of LCH2. For example, reducing the priority value to "1" is equivalent to LCH1, which means that the terminal will subsequently transmit the data streams of LCH1 and LCH2 simultaneously.

[0212] Step 4-2: Increase the priority of the second logical channel LCH2 accordingly. Specifically, reduce the parameter value of the priority field in the information unit LogicalChannelConfig of LCH2. For example, adjust the priority value to "2", which is incremented relative to LCH1. The data stream priority of LCH2 is second only to the data stream priority of LCH1. After allocating sufficient uplink resources for the data stream in LCH1, the terminal will first choose to allocate the remaining resources to LCH2.

[0213] Wherein, step 4-1 and step 4-2 represent two methods under the same embodiment.

[0214] Embodiment seven:

[0215] Taking two logical channels as an example, when the difference between the priority value of the first logical channel LCH1 and the priority value of the second logical channel LCH2 exceeds the preset threshold N (ie, the fifth preset threshold), the terminal will adjust the priorities of LCH1 and LCH2.

[0216] The logical channel identifier of LCH1 is LCID1, and the logical channel identifier of LCH2 is LCID2. LCH1 has a higher priority than LCH2.

[0217] Step 1: Assuming that the data stream in LCH1 and the data stream in LCH2 both arrive at the buffer of the terminal, LCH1 has a higher priority than LCH2.

[0218] Step 2-1: If the difference between the priority values ​​of the two logical channels exceeds the preset threshold N, the priorities of the two logical channels will be increased accordingly. Specifically, the parameter value of the priority field in the information unit LogicalChannelConfig of LCH2 is reduced, and the priority value is reduced to the same as the priority value of LCH1, which means that the terminal will subsequently transmit the data streams of LCH1 and LCH2 at the same time.

[0219] Step 2-2: If the difference between the priority values ​​of the two logical channels exceeds the preset threshold N, the priorities of the two logical channels will be increased accordingly. Specifically, the priority value of LCH2 is reduced to only 1 greater than the priority value of LCH1, and the priority of the LCH2 data stream is increased relative to LCH1. The priority of the LCH2 data stream is second only to the priority of the LCH1 data stream. After allocating sufficient uplink resources for the data stream in LCH1, the terminal will first choose to allocate the remaining resources to LCH2.

[0220] Step 2-3: If the difference between the priority values ​​of the two logical channels exceeds the preset threshold N, the priorities of the two logical channels will be increased accordingly. Specifically, the priority values ​​of LCH1 and LCH2 are weighted averaged, for example, the priority values ​​are adjusted to the average of the priority values ​​of LCH1 and LCH2, which means that the data streams of LCH1 and LCH2 have the same priority, and the terminal will send the data streams in LCH1 and LCH2 with a shorter time difference in subsequent transmissions.

[0221] Among them, step 2-1, step 2-2 and step 2-3 represent three methods under the same embodiment.

[0222] Embodiment eight:

[0223] Taking two logical channels as an example, when the PSDB parameter of the first logical channel LCH1 is lower than the preset threshold T, the terminal will adjust the priorities of the first logical channel LCH1 and the second logical channel LCH2.

[0224] The logical channel identifier of LCH1 is LCID1, and the logical channel identifier of LCH2 is LCID2.

[0225] The value of the preset delay threshold T' refers to the transmission waiting time threshold of each data stream of the multi-modal communication.

[0226] Step 1: Assuming that the data flow in LCH1 arrives at the terminal buffer first, and the data flow related to the data flow in LCH2 arrives at the terminal buffer later, the PSDB parameter of the PDU set in LCH1 is smaller than the PSDB parameter of the PDU set in LCH2.

[0227] Step 2: The terminal monitors the PSDB parameter value of each logical channel in real time. When the PSDB parameter value of LCH1 is lower than the preset threshold T, the terminal will increase the priority of LCH1, specifically by reducing the parameter value of the priority field in the information unit LogicalChannelConfig of LCH1. For example, reducing the priority value to "1" means that the data stream of LCH1 has the highest priority, and the terminal will first send the data stream in LCH1 in subsequent transmissions.

[0228] Step 3: The terminal searches for a second logical channel LCH2 related to the first logical channel LCH1.

[0229] Step 4-1: Increase the priority of the second logical channel LCH2 accordingly. Specifically, reduce the parameter value of the priority field in the information unit LogicalChannelConfig of LCH2. For example, reducing the priority value to "1" is equivalent to LCH1, which means that the terminal will subsequently transmit the data streams of LCH1 and LCH2 simultaneously.

[0230] Step 4-2: Increase the priority of the second logical channel LCH2 accordingly. Specifically, adjust the priority value to "2", which is increased relative to LCH1. The data flow priority of LCH2 is second only to the data flow priority of LCH1. After allocating sufficient uplink resources for the data flow in LCH1, the terminal will first choose to allocate the remaining resources to LCH2.

[0231] Wherein, step 4-1 and step 4-2 represent two methods under the same embodiment.
