Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0122] XR refers to a real and virtual combination of a human-computer interactive environment generated by computer technology and wearable devices. XR is a general term for a variety of technologies such as augmented reality (AR), virtual reality (VR), and mixed reality (MR). By integrating the visual interaction technologies of AR, VR, and MR, the user is brought into a virtual world and a real world that seamlessly transitions between the two. In XR services, a service flow is usually composed of multiple data flows (such as quality of service flow (QoS flow)), and has a very large amount of data.

[0123] In practical applications, the transmission of the service flow of the XR service needs to meet certain delay requirements, especially some data flows need to arrive at the network function at the same time for synchronous processing (for example, joint decoding). The delay of any one data flow will cause the synchronous processing of multiple data flows to fail. Therefore, in 5G technology, the priority of the logic channel (LC) is used to schedule the data flow. However, the scheduling of the network device is dynamic, so in some cases, even if some data flow belongs to a low-priority logic channel, if some data packet has not been scheduled for a long time, the terminal needs to send a buffer status report (BSR) to notify the network as soon as possible.

[0124] In some embodiments, a DSR process is introduced, that is, the terminal can trigger a DSR process, which carries delay-related information of data transmission, for example, information that the uplink data has been long without being scheduled, resulting in the remaining time of the data packet being less than a certain threshold. The remaining time of the data packet is the time to packet discard, and the remaining time can be determined according to the discard timer of the packet data convergence protocol (PDCP), for example.

[0125] In some embodiments, the DSR process is used to provide the delay state of the logic channel group (LCG) to the serving base station. The delay state of the LCG includes the remaining time, which is the minimum remaining value of the discard timer of the PDCP in the buffered service data unit (SDU) of the LCG, and the delay critical uplink data of the LCG associated with the data volume calculation process of the associated radio link control (RLC) entity and PDCP entity.

[0126] In some embodiments, a radio resource control (RRC) controls the DSR procedure by configuring the following parameters: remainingTimeThreshold, which refers to a remaining time threshold for triggering the DSR of the LCG.

[0127] In some embodiments, RAN4 introduces some scheduling restrictions. That is, in some time periods, the transceiver of the terminal cannot perform data transmission and reception because it needs to perform measurements. On the one hand, the time period of the scheduling restriction can include a measurement gap (MG), that is, a time period agreed by the network and the terminal for measurement. In this time period, the terminal can focus on measurement and does not need to perform data transmission and reception because the network device has agreed that the terminal does not need to perform transmission and reception. On the other hand, the time period of the scheduling restriction can also include an SMTC window. In the SMTC window, the terminal cannot perform data transmission and reception in the time period for performing SSB measurement.

[0128] In some embodiments, the above scheduling restriction can be understood as Tx / Rx in gaps / restrictions that are caused by RRM measurements.

[0129] However, considering that the XR service is a service that is more sensitive to scheduling delay. If the data stream of the XR service cannot be scheduled in time, a large number of data packets will be discarded. Therefore, for the XR service, how the terminal performs data transmission when encountering scheduling restrictions is a problem to be solved.

[0130] In some embodiments, the terms “scheduling restriction”, “scheduling gap”, “transmission gap”, “transmission restriction”, “uplink / downlink restriction”, “uplink / downlink gap”, “transmission / reception restriction”, and “Tx / Rx restriction” can be replaced with each other.

[0131] In some embodiments, the terms “logical channel” and “logical channel group” can be replaced with each other.

[0132] To this end, the embodiments of the present disclosure provide a communication method, a terminal, a network device, a communication device, and a storage medium, which realize how to perform data transmission when encountering scheduling restrictions, so that data whose delay budget is about to expire can be transmitted in time, and the delay requirement of the XR service is met.

[0133] FIG. 2A is a first interaction schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2A, the embodiment of the present disclosure relates to a communication method, which is performed by the above-mentioned communication system. The above-mentioned method comprises steps S2110 to S2140.

[0134] In step S2110, the terminal sends second information.

[0135] In some embodiments, the network device receives the second information.

[0136] In some embodiments, the second information is used to indicate whether the terminal supports the first function. Alternatively, the second information is used to indicate the capability of the terminal to the first function.

[0140] In some embodiments, the name of the second information is not limited, for example, it can be indication information, capability information, assistance information, etc. In an example, the second information can be UE capability information or UE assistance information.

[0141] In some embodiments, the second information is used to indicate that the terminal supports the first function, or the second information is used to indicate that the terminal does not support the first function.

[0142] In some embodiments, the second information indicates that the terminal supports the first function, which can be understood as: the second information indicates that the terminal supports determining whether to perform data transmission on the first time unit. Alternatively, the second information indicates that the terminal supports deciding whether to perform data transmission on the first time unit. Alternatively, the second information indicates that the terminal supports making a decision on whether to perform data transmission on the first time unit.

[0143] In some embodiments, the second information can be carried in an RRC message, a media access control (MAC)-control element (CE) message, etc.

[0144] In some embodiments, different terminals have different capabilities for the first function. Understandably, some terminals can support the first function, and some terminals can not support the first function.

[0145] In some embodiments, the same terminal has different capabilities for the first function in different frequency ranges (FRs). Understandably, the terminal can support the first function in FR1, and can not support the first function in FR2.

[0146] In some embodiments, after the network device receives the second information, the network device can know the capability of the terminal for the first function, so that the capability interaction between the network device and the terminal about the first function is realized, and a consistent understanding is reached.

[0147] In some embodiments, the network device can also determine whether to perform data transmission with the terminal in the first time unit according to the second information. In some embodiments, the network device receives the above-mentioned second information, and the second information indicates that the terminal supports the first function, at this time, the network device considers that the terminal is likely to perform data transmission in the first time unit. At this time, the network device can determine to perform data transmission with the terminal in the first time unit. In some embodiments, the network device receives the above-mentioned second information, and the second information indicates that the terminal does not support the first function, at this time, the network device considers that the terminal is not likely to perform data transmission in the first time unit. At this time, the network device can determine not to perform data transmission with the terminal in the first time unit.

[0148] In some embodiments, step S2110 can be omitted, at this time, the terminal can be set by default to support the first function or not to support the first function.

[0149] In step S2120, it is determined whether to perform data transmission in the first time unit.

[0150] In some embodiments, the terminal can determine whether to perform data transmission with the network device in the first time unit. In some embodiments, the terminal can determine whether to receive downlink data sent by the network device in the first time unit.

In some embodiments, the network device can determine whether to receive uplink data sent by the terminal in the first time unit. In some embodiments, the network device can determine whether to send downlink data to the terminal in the first time unit.

[0152] In some embodiments, the first time unit can be used for the terminal to perform the scheduling restriction. In some embodiments, the first time unit can be a plurality of continuous time units. In some embodiments, the first time unit can also be a plurality of discontinuous time units. In some embodiments, the counting unit of the above-mentioned time unit can be an absolute time unit, such as millisecond (ms), second (s), minute (min), etc. In some embodiments, the counting unit of the above-mentioned time unit can be a relative time unit, such as frame, subframe, slot, subslot, symbol, etc. In an example, the symbol can be understood as an orthogonal frequency-division multiplexing (OFDM) symbol.

[0153] In some embodiments, the first time unit can be contained in a first time period, and the first time period can be configured by the network device. The first time unit can be a plurality of continuous time units in the first time period. In some embodiments, the first time unit can also be a plurality of discontinuous time units in the first time period. In an example, the network device can configure the first time period to the terminal through a message such as an RRC message, a MAC CE, etc.

[0154] In some embodiments, in the first time unit, the terminal can perform the scheduling restriction, i.e., the terminal performs the measurement without performing the data transmission. In some embodiments, in order to meet the requirement of the data transmission, in the first time unit, the terminal can also not perform the scheduling restriction, but perform the data transmission, i.e., the terminal performs the data transmission without performing the measurement.

[0155] In some embodiments, the above-mentioned “not performing the data transmission” can also be understood as “not expected to perform the data transmission”, “not selected to perform the data transmission”, “should not perform the data transmission”, “not required to perform the data transmission”, etc.

[0156] In some embodiments, the above-mentioned “performing the measurement” can also be understood as “expected to perform the measurement”, “selected to perform the measurement”, “should perform the measurement”, etc.

[0157] In some embodiments, the first time unit can include at least one of the following: a time unit in which the terminal does not perform the data transmission, a time unit in which the terminal performs the measurement.

[0158] In some embodiments, in the case that the terminal does not perform the data transmission in the first time unit, the terminal can perform other operations in addition to the data transmission in the first time unit, and is not limited to performing the measurement.

[0159] In some embodiments, the first time unit can comprise at least one of: a measurement interval, an SMTC window.

[0160] In some embodiments, the first time unit can be used for measurement of a channel status information-reference signal (CSI-RS). In some embodiments, the first time unit can be a measurement interval for CSI-RS measurement.

[0161] It should be noted that the first time unit can be a time unit for performing other measurements, or a time unit for performing other operations in addition to measurement, which are not limited in the embodiments of the present disclosure.

[0162] In some embodiments, the network device does not expect the terminal to perform data transmission in the first time unit. In some embodiments, the network device expects the terminal to perform measurement in the first time unit.

[0163] In some embodiments, the terminal can perform SSB-based measurement in the SMTC window.

[0164] In some embodiments, the terminal can perform layer 1 measurement or layer 3 measurement in the first time unit.

[0165] In some embodiments, in a case where data transmission performed by the terminal is prioritized over the scheduling restriction, the first time unit can also be used for the terminal to perform at least one of data transmission and no measurement.

[0166] In some embodiments, the terminal can determine whether data transmission performed by the terminal is prioritized over the scheduling restriction according to a case of data to be transmitted, a priority of data transmission performed by the terminal, and the like. In an embodiment, in a case where data transmission performed by the terminal is prioritized over the scheduling restriction, the terminal determines to perform data transmission in the first time unit. In some embodiments, in a case where data transmission performed by the terminal is not prioritized over the scheduling restriction, the terminal determines to perform the scheduling restriction, i.e., measurement, in the first time unit.

[0167] In some embodiments, that data transmission performed by the terminal is prioritized over the scheduling restriction can be understood as one of: the data to be transmitted has a specific scheduling requirement, and a priority of data transmission of the terminal in the first time unit is higher than a priority of the scheduling restriction.

[0168] In some embodiments, that data transmission performed by the terminal is prioritized over the scheduling restriction can be understood as one of: the data to be transmitted does not have a specific scheduling requirement, and a priority of data transmission of the terminal in the first time unit is lower than a priority of the scheduling restriction.

[0169] In some embodiments, the terminal determines to perform the data transmission in the first time unit in a case that the priority of the data transmission of the terminal in the first time unit is higher than the priority of the scheduling restriction.

[0170] In some embodiments, the terminal determines not to perform the data transmission in the first time unit in a case that the priority of the data transmission of the terminal in the first time unit is lower than the priority of the scheduling restriction.

[0171] In some embodiments, the terminal determines to perform the data transmission in the first time unit in a case that the priority of the data transmission of the terminal in the first time unit is higher than the priority of the scheduling restriction.

[0172] In some embodiments, the terminal determines not to perform the data transmission in the first time unit in a case that the priority of the data transmission of the terminal in the first time unit is lower than the priority of the scheduling restriction.

[0173] In some embodiments, the terminal can determine whether to perform the data transmission in the first time unit according to a condition of the data to be transmitted. In some embodiments, the condition of the data to be transmitted can include whether the data to be transmitted has a specific scheduling requirement. In an embodiment, in a case that the data to be transmitted has the specific scheduling requirement, the terminal can determine to perform the data transmission in the first time unit. In an embodiment, in a case that the data to be transmitted does not have the specific scheduling requirement, the terminal can determine not to perform the data transmission in the first time unit.

[0174] In some embodiments, the specific scheduling requirement can be understood as an urgent scheduling requirement. In an embodiment, the data having the urgent scheduling requirement can include urgent scheduling data. In an example, the data having the urgent scheduling requirement can include data with a delay budget less than a preset value. In some embodiments, the delay budget of the data can be understood as the remaining time of the data. In an example, the delay budget of the data can be a package delay budget (PDB). In an example, the data having the urgent scheduling requirement can also include data whose transmission cannot meet a synchronization requirement.

[0175] In some embodiments, for the above data having the specific scheduling requirement, the priority of the terminal performing the data transmission in the first time unit can be higher than the priority of performing the measurement, or the priority of the terminal performing the data transmission in the first time unit can also be lower than the priority of performing the measurement.

[0176] In some embodiments, the priority of the terminal performing data transmission on the data with the specific scheduling requirement can be higher than the priority of performing measurement in the first time unit. In this case, when the priority of the terminal performing data transmission on the specific data is higher than the priority of the scheduling restriction in the first time unit, the terminal can determine to perform data transmission in the first time unit.

[0177] In some embodiments, the priority of the terminal performing data transmission on the data without the specific scheduling requirement can be lower than the priority of performing measurement in the first time unit. In this case, when the priority of the terminal performing data transmission on the specific data is lower than the priority of the scheduling restriction in the first time unit, the terminal can determine not to perform data transmission in the first time unit.

[0178] In some embodiments, the data with the urgent scheduling requirement can be mutually replaced with the urgent scheduling data.

[0179] In some embodiments, the preset value can be configured by the network device for the terminal, preconfigured according to a protocol, or determined by negotiation between the network device and the terminal, which is not limited in the embodiments of the present disclosure.

[0180] In some embodiments, when the terminal detects that the delay budget of the data to be transmitted is less than the preset value, the terminal can determine that the data to be transmitted is the data with the urgent scheduling requirement, and further determine to perform data transmission in the first time unit, i.e., to send the data with the urgent scheduling requirement to the network device in the first time unit. In some embodiments, the terminal sending the data with the urgent scheduling requirement to the network device in the first time unit can also be understood as that the terminal preferentially sends the data with the urgent scheduling requirement to the network device in the first time unit.

[0181] In some embodiments, when the terminal detects that the data to be transmitted cannot meet the synchronization requirement, the terminal can determine that the data to be transmitted is the data with the urgent scheduling requirement, and further determine to perform data transmission in the first time unit, i.e., to send the data with the urgent scheduling requirement to the network device in the first time unit. In some embodiments, the terminal sending the data with the urgent scheduling requirement to the network device in the first time unit can also be understood as that the terminal preferentially sends the data with the urgent scheduling requirement to the network device in the first time unit.

[0182] In some embodiments, the data to be transmitted can be transmitted on the first logical channel. In an example, the first logical channel is a logical channel on which the delay budget of data is less than a preset value. The terminal detects that there is data to be transmitted on some logical channels on which the delay budget is less than the preset value, in which case the logical channels are the first logical channels, and the data on the logical channels on which the delay budget is less than the preset value is the data to be transmitted. In an example, the first logical channel is a logical channel on which the transmission of data cannot meet the synchronization requirement. The terminal detects that the transmission of data on some logical channels cannot meet the synchronization requirement, in which case the logical channels are the first logical channels, and the data on the logical channels on which the transmission cannot meet the synchronization requirement is the data to be transmitted.

[0183] In some embodiments, the specific scheduling requirement can also be understood as that the data to be transmitted has triggered the DSR. In some embodiments, the terminal detects that the data of some logical channels has triggered the DSR due to long time of being unscheduled, and the logical channels on which the data triggering the DSR are the first logical channels. Then, the terminal can determine the data to be transmitted on the logical channels as the data having the specific scheduling requirement, and further determine to perform the data transmission in the first time unit, i.e., to send the data to be transmitted on the logical channels associated with the triggered DSR to the network device in the first time unit. In some embodiments, the terminal sending the data having the specific scheduling requirement to the network device in the first time unit can also be understood as that the terminal preferentially sends the data to be transmitted on the logical channels associated with the triggered DSR to the network device in the first time unit.

[0184] In some embodiments, for the data to be transmitted, the priority of the data transmission of the terminal in the first time unit is higher than the priority of the scheduling limit. In this case, the terminal determines to perform the data transmission in the first time unit. Conversely, for other data, the priority of the data transmission of the terminal in the first time unit is lower than the priority of the scheduling limit. In this case, the terminal determines to perform the measurement in the first time unit.

[0185] In some embodiments, after receiving the second information, and the second information indicates that the terminal supports the first function, the network device considers that the terminal is likely to perform the data transmission in the first time unit. At this time, the network device can determine to perform the data transmission with the terminal in the first time unit. Then, the network device can listen to the uplink channel. If the terminal determines to perform the data transmission in the first time unit, the network device can receive the uplink data. If the terminal determines not to perform the data transmission in the first time unit, the network device cannot receive the uplink data.

[0186] In some embodiments, the network device receives the second information, and the second information indicates that the terminal does not support the first function. In this case, the network device considers that the terminal is impossible to perform data transmission in the first time unit. In this case, the network device can determine that the terminal does not perform data transmission in the first time unit. Then, the network device can not listen to the uplink channel, or listen to the uplink channel but not detect the uplink data.

[0187] In some embodiments, in step S2120, the terminal determines that, in the case that the terminal performs data transmission in the first time unit, the terminal can determine to perform measurement in the first time unit. In this case, the terminal can perform step S2130.

[0188] In some embodiments, in step S2120, the terminal determines that, in the case that the terminal does not perform data transmission in the first time unit, the terminal can determine to perform measurement in the first time unit. In this case, the terminal can perform step S2140.

[0189] In some embodiments, in step S2120, the network device determines that, in the case that the terminal performs data transmission in the first time unit, the network device can determine that the terminal performs data transmission and does not perform measurement in the first time unit. In this case, the network device can perform step S2130.

[0190] In some embodiments, in step S2120, the network device determines that, in the case that the terminal does not perform data transmission in the first time unit, the network device can determine that the terminal performs measurement and does not perform data transmission in the first time unit. In this case, the network device can neither send downlink data to the terminal nor listen to the uplink channel in the first time unit, or the network device can also listen to the uplink channel in the first time unit but not receive the uplink data.

[0191] In step S2130, the terminal and the network device perform data transmission in the first time unit.

[0192] In some embodiments, the terminal can receive the downlink data sent by the network device in the first time unit. In some embodiments, the terminal can send the uplink data to the network device in the first time unit.

In some embodiments, the terminal receives data on a logical channel for which data transmission cannot meet synchronization requirements transmitted by the network device in the first time unit.

[0197] In step S2140, the terminal performs measurement in the first time unit.

[0198] In some embodiments, the terminal performs one or more measurements in the first time unit.

[0199] In some embodiments, after completing the measurement, the terminal can report the measurement result to the network device, or can not report the measurement result to the network device.

[0341] Hereinafter, the technical solutions of the embodiments of the present disclosure are exemplarily described through specific implementations.

[0342] In some embodiments, the communication method includes a strategy of how the terminal transmits data within a specific time period (e.g., within the first time period).

[0343] In some embodiments, the specific time period includes at least a time period of scheduling restriction (e.g., the first time unit), and can also include a time period of non-scheduling restriction.

[0344] In some embodiments, the time period of scheduling restriction is a time period in which the terminal cannot transmit and receive data; usually because the terminal needs to perform measurement. In an example, the time period of scheduling restriction can be a measurement gap (Measurement GAP); in an example, the time period of scheduling restriction can be an SMTC window.

[0345] In some embodiments, the terminal determines whether to perform data transmission in the time period of scheduling restriction within the specific time period according to the data to be transmitted or the indication of the base station.

[0346] In some embodiments, if the data to be transmitted includes emergency scheduling data (e.g., data with specific scheduling requirements), the data transmission priority of the terminal is higher than the scheduling restriction in the time period of scheduling restriction within the specific time period. At this time, the terminal normally performs data transmission and does not perform measurement. It can also be understood that the terminal determines whether to perform data transmission, but the base station can only perform blind detection in this time period, which can detect data or can not detect data.

[0347] In some embodiments, the terminal finds that the remaining time of the data of some logical channels is less than a threshold given by the network, and these data are emergency scheduling data.

[0348] In some embodiments, the terminal finds that the transmission of the data of some logical channels cannot meet the synchronization requirement, and these data are emergency scheduling data.

[0349] In some embodiments, the terminal can perform priority transmission of the emergency scheduling data in the time period of scheduling restriction within the specific time period.

[0350] In some embodiments, if the base station indicates that the data transmission priority level of the terminal is higher than the scheduling limit in the time period of the scheduling limit in the specific time period, the terminal performs data transmission normally and does not perform measurement.

[0351] In some embodiments, the base station can carry an indication in the DCI grant to indicate that the current grant is used for data transmission.

[0352] In some embodiments, for the terminal, the terminal follows the indication of the base station, and the data transmission priority level of the terminal is higher than the scheduling limit in the time period of the scheduling limit in the specific time period. At this time, the terminal performs data transmission normally and does not perform measurement.

[0353] In some embodiments, for the terminal, the terminal follows the indication of the base station, and the specific data transmission priority level of the terminal is higher than the scheduling limit in the time period of the scheduling limit in the specific time period. At this time, the terminal only performs data transmission of a specific logical channel. For example, the specific logical channel can be a logical channel whose data remaining time is less than a given threshold of the network, or a logical channel that triggers DSR reporting.

[0354] In some embodiments, the base station can carry an indication in the DCI grant to indicate which data transmission is authorized. For example, the grant specifically indicates which logical channel or logical channel group.

[0355] In some embodiments, for the terminal, the terminal follows the indication of the base station, and the data transmission priority level of the specified logical channel of the terminal is higher than the scheduling limit in the time period of the scheduling limit in the specific time period. At this time, the terminal only performs data transmission of the network specified logical channel or logical channel group.

[0356] In some embodiments, the specific time period is a time range that the network indicates to the terminal in advance. In an example, the configuration of the specific time period can be an RRC message or a MAC CE issued by the network.

[0357] In some embodiments, the above strategy can be overwritten by other strategies, at this time, if the base station reissues the strategy, such as the priority of the terminal's data transmission in the time period of the scheduling limit is higher than the scheduling limit, the terminal normally performs data transmission and does not perform measurement, that is, executes according to the new strategy. If the base station reissues the strategy, such as the priority of the terminal's data transmission in the time period of the scheduling limit is lower than the scheduling limit, the terminal does not perform data transmission and performs measurement, that is, executes according to the new strategy.

[0358] In some embodiments, the terminal reports a new terminal capability to indicate the terminal's capability of supporting the strategy of how to perform data transmission in a specific time period. In some embodiments, the terminal capability can be per UE or per FR.
