Description

Communication method, terminal, network device, communication device, and communication system TECHNICAL FIELD

[0001] The present disclosure relates to the field of wireless communication, and in particular, to a communication method, a terminal, a network device, a communication device, and a communication system. BACKGROUND

[0002] In an extended reality (XR) service, a service flow is usually composed of multiple data flows, and has a very large amount of data. In the process of implementing the XR service using a 5th generation mobile communication technology (5G technology), the transmission of the service flow of the XR service needs to meet certain latency requirements, and in particular, some data flows need to arrive at a 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.

[0029] According to the present embodiment, the terminal can determine to perform data transmission on the first data preferentially in the first time unit in which the scheduling restriction exists. In this way, the terminal can perform data transmission on the first data preferentially in the first time unit in which the scheduling restriction exists, in a case that a delay budget of the first data is about to expire, for example. Then, the terminal can perform transmission on the data whose delay budget is about to expire in time, avoiding the data packet from being discarded, so as to meet the delay requirement of the service corresponding to the first data.

In this way, the terminal can preferentially perform data transmission on the first data at the first time unit with scheduling restriction in a case such as expiration of delay budget of the first data.

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

[0110] XR refers to a real and virtual combination of an environment that can be interacted with by a computer technology and wearable devices. XR is a collective term for augmented reality (AR), virtual reality (VR), mixed reality (MR), and the like. By fusing the visual interaction technologies of AR, VR, and MR, the user is brought into a "immersive" experience of seamless conversion between the virtual world and the real world. 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.

[0111] In actual 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 flows belong to a low-priority logic channel, if some data packets have 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.

[0112] In some embodiments, a DSR process is introduced, that is, the terminal can trigger the DSR process, which carries delay-related information of data transmission, for example, information that the uplink data has been long without being scheduled, causing the remaining time of the data packet to be 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.

[0113] In some embodiments, the DSR procedure is used to provide a delay status of a logic channel group (LCG) to a serving base station. The delay status of the LCG includes a remaining time, which refers to the minimum remaining value of a discard timer for PDCP in service data units (SDUs) buffered for the LCG (as specified in clause 7.3 in TS 38.323), and delay-critical uplink data for the LCG associated with a data volume computation procedure for an associated radio link control (RLC) entity and PDCP entity (as specified in clause 5.5 in TS 38.322 and clause 5.6 in TS 38.323).

[0114] 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 DSR for an LCG.

[0115] 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), i.e., 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.

[0116] In some embodiments, the above scheduling restriction can be understood as a Tx / Rx in gaps / restrictions that are caused by RRM measurements.

[0117] However, considering that XR traffic is a kind of traffic that is more sensitive to scheduling delay. If the data stream of the XR traffic cannot be scheduled in time, a large number of data packets will be discarded. Therefore, for XR traffic, how the terminal performs data transmission when encountering scheduling restrictions is a problem to be solved.

[0118] In some embodiments, the terms "scheduling restriction", "scheduling gap", "transmission gap", "transmission restriction", "uplink / downlink restriction", "uplink / downlink gap", "transmit / receive restriction", "Tx / Rx restriction" can be replaced with each other.

[0119] In some embodiments, the terms "logical channel", "logical channel group" can be replaced with each other.

[0120] To this end, the embodiments of the present disclosure provide a communication method, a terminal, a network device, a communication system, a storage medium and a program product, which realize how to perform data transmission when a scheduling restriction is encountered, so that data whose delay budget is about to expire can be transmitted in time, and the delay requirement of XR service is met.

[0121] FIG. 2 is an interaction schematic diagram of a communication method according to an embodiment of the present disclosure. The communication method related by the embodiments of the present disclosure can be applied to the communication system 100. As shown in FIG. 2, the communication method of the embodiments of the present disclosure includes steps S201 to S204.

[0122] In step S201, the network device 102 sends first information to the terminal 101.

[0123] In some embodiments, the terminal 101 can receive the first information.

[0124] In some embodiments, the network device 102 indicates to the terminal 101 to prioritize the data transmission of the first data on the first time unit by sending the first information. In some embodiments, the network device 102 can indicate to the terminal 101 to prioritize the data transmission of the first data on the first time unit by explicit indication or implicit indication.

[0125] In some embodiments, the network device 102 indicates to the terminal 101 to prioritize the data transmission of the first data on the first time unit by sending explicit indication (such as the first information). In an example, the first information can be used to indicate to the terminal 101 to prioritize the data transmission of the first data on the first time unit. In some embodiments, the first information can be used to inform the terminal 101 that the terminal 101 can perform transmission and / or reception of the first data on the first time unit.

[0126] In some embodiments, the network device 102 indicates to the terminal 101 to allow the terminal 101 to perform data transmission on the first data preferentially on the first time unit by sending an implicit indication. In an example, the first information can be used to indicate the terminal 101 to deactivate a measurement gap on the first time unit. In some embodiments, the first information can be used to indicate the terminal 101 to deconfigure a measurement gap on the first time unit. In this way, the terminal 101 is allowed to perform data transmission on the first data preferentially on the first time unit due to the invalidation of the measurement gap.

[0127] In some embodiments, the name of the first information is not limited, which can be, for example, indication information, deactivation instruction, measurement gap configuration information, preferential transmission permission information, preferential transmission open indication, etc.

[0128] In some embodiments, the terminal 101 performing data transmission on the first data preferentially on the first time unit can be understood as the terminal 101 performing data transmission on the first data preferentially on the first time unit compared to performing scheduling restriction. In some embodiments, the terminal performing data transmission on the first data is prior to performing scheduling restriction.

[0129] In some embodiments, the first time unit can be used for the terminal to perform 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 non-continuous 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.

[0130] In some embodiments, the first time unit can be contained in a first time period, which 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 non-continuous time units in the first time period. In an example, the network device can configure the first time period to the terminal through messages such as RRC message, MAC CE, etc.

[0131] In some embodiments, at the first time unit, the terminal can perform a scheduling restriction, i.e., the terminal performs measurement without performing data transmission. In some embodiments, in order to meet the requirement of data transmission of the first data, at the first time unit, the terminal can also not perform the scheduling restriction, but perform data transmission, i.e., the terminal performs data transmission without performing measurement.

[0132] In some embodiments, the above-mentioned "not performing data transmission" can also be understood as "not expected to perform data transmission", "not selected to perform data transmission", "not supposed to perform data transmission", "not required to perform data transmission", etc.

[0133] In some embodiments, the above-mentioned "performing measurement" can also be understood as "expected to perform measurement", "selected to perform measurement", "supposed to perform measurement", "required to perform measurement", etc.

[0134] 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 data transmission, a time unit in which the terminal performs measurement.

[0135] In some embodiments, in the case that the terminal does not perform data transmission at the first time unit, the terminal can perform other operations in addition to data transmission at the first time unit, and is not limited to performing measurement.

[0136] In some embodiments, in the case that the first data needs to be transmitted preferentially, the first time unit is also used for the terminal to perform data transmission and / or not to perform measurement.

[0137] In some embodiments, in the case that the first information indicates that the terminal 101 is allowed to perform data transmission preferentially on the first data at the first time unit, the terminal determines that the first data needs to be transmitted preferentially, and at this time, the first time unit is also used for the terminal to perform data transmission and / or not to perform measurement.

[0138] In some embodiments, the first time unit can include at least one of the following: a measurement interval, an SSB measurement time configuration (SMTC) window.

[0139] In some embodiments, the first time unit can be used for measurement of a channel state information-reference signal (CSI-RS). In some embodiments, the first time unit can be a measurement interval for CSI-RS measurement.

[0140] 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, and the embodiments of the present disclosure do not make specific limitation thereto.

[0141] In some embodiments, the first data can include at least one of the following: data with a preset scheduling requirement, data of a preset type. In some embodiments, the first data can have a preset type and / or a preset scheduling requirement.

[0142] In some embodiments, the data with a preset scheduling requirement can be data with an urgent scheduling requirement. In some embodiments, the data with an urgent scheduling requirement can include delay critical data. In an example, the delay critical data can be data with a higher requirement for delay. In an example, the delay critical data can be data sensitive to delay. It can be understood that, since the delay critical data has a higher requirement for delay and / or is sensitive to delay, it has an urgent scheduling requirement.

[0143] In some embodiments, the data of a preset type can include at least one of the following: data with a remaining time less than or equal to a preset threshold, data for which scheduling has lagged and a multi-stream synchronization threshold between data streams cannot be met.

[0144] In some embodiments, a scheduling waiting time can be set for the data in the process of scheduling the data. The scheduling waiting time can be a time from when the data starts waiting for scheduling to when the data is discarded. In other words, in the case where the scheduling waiting time is exhausted, the data can be discarded.

[0145] In some embodiments, the scheduling waiting time can be counted by a timer. In an example, the timer can be set to count the scheduling waiting time. In an example, in the case where the timer times out, the corresponding data can be discarded. It can be understood that the timer can be referred to as a “discard timer”.

[0146] In some embodiments, the remaining time can refer to a time length from when the data is discarded. In an example, the remaining time can be indicated by the above-mentioned timer. In some embodiments, the data of a preset type can be data with a remaining time less than or equal to a preset threshold. In an example, the data of a preset type can be data for which the remaining time of the corresponding timer is less than or equal to a preset threshold.

[0147] In some embodiments, there can be an association between the multiple data streams. In an embodiment, there can be an association between the content of the multiple data streams. For example, the multiple data streams can correspond to one multimedia service, one or more of the multiple data streams can carry video data, and one or more of the multiple data streams can carry audio data. In this case, there can be a requirement of synchronization between the multiple data streams, for example, to ensure audio-video synchronization. In some embodiments, there can be a synchronization threshold between the multiple data streams. The synchronization threshold can ensure synchronization between the multiple data streams.

[0148] In some embodiments, the data for which scheduling has lagged and for which the multi-stream synchronization threshold between data streams cannot be met can be data of a certain type. In some embodiments, in the multiple data streams with an association, the scheduling of data in one or more data streams can lag behind the data in other data streams among these data streams, and the synchronization threshold between the latter data stream and the other data streams can not be met. In this case, the data in the latter data stream is the data for which scheduling has lagged and for which the multi-stream synchronization threshold between data streams cannot be met.

[0149] In some embodiments, the data with a preset scheduling requirement can be of a preset type. In some embodiments, the data with a preset scheduling requirement can be considered as data of a preset type.

[0150] In some embodiments, the data of a preset type can have a preset scheduling requirement. In some embodiments, the data of a preset type can be considered as data with a preset scheduling requirement.

[0151] In some embodiments, the first information can be carried in a radio resource configuration (RRC) message.

[0152] In some embodiments, the first information can be carried in a media access control-control element (MAC-CE) message.

[0153] In some embodiments, the first information can be carried in downlink control information (DCI). In some embodiments, the first information in the DCI can be used to indicate the first time unit. In some embodiments, the first information in the DCI can be used to indicate that data transmission can be prioritized over measurement in the first time unit. In some embodiments, the DCI can be used to indicate a measurement interval. At this time, the first information in the DCI can be used to indicate that data transmission can be prioritized for execution within the first time unit.

[0154] In step S202, the network device 102 sends the second information to the terminal 101.

[0155] In some embodiments, the terminal 101 can receive the second information.

[0156] In some embodiments, the second information can be used to instruct the terminal 101 to perform data transmission on the first data preferentially in the first time unit.

[0157] In some embodiments, the second information can be used to trigger the terminal 101 to perform data transmission on the first data preferentially in the first time unit.

[0158] In some embodiments, the second information can be carried in an RRC message.

[0159] In some embodiments, the first information can be carried in a MAC CE message. In some embodiments, the MAC CE message can be a measurement gap deactivation. At this time, the first information in the measurement gap deactivation can be used to indicate that the time period of the measurement gap is the first time unit. In other words, the measurement gap deactivation in the MAC CE message can be used to instruct to perform data transmission on the first data preferentially in the time period of the measurement gap.

[0160] In some embodiments, the first information can be carried in a DCI. In some embodiments, the first information in the DCI can be used to indicate the first time unit. In some embodiments, the DCI can be used to indicate the time period of the measurement gap. In other words, the first information in the DCI can be used to indicate that the time period of the measurement gap is the first time unit. At this time, the first information in the DCI can be used to instruct to perform data transmission preferentially in the first time unit.

[0161] In some embodiments, step S202 is optional. In some embodiments, step S202 can be performed. In some embodiments, step S202 can not be performed.

[0162] In some embodiments, in the case where step S202 is performed, the first information and the second information can be sent respectively or jointly. In some embodiments, the network device 102 can send the first information to the terminal 101 first, and then send the second information to the terminal 101. At this time, the first information and the second information can be carried in different messages or signaling. In some embodiments, the network device 102 can send the first information and the second information to the terminal 101 simultaneously. At this time, the first information and the second information can be carried in the same message or signaling. For example, the first information and the second information can be carried in the same RRC message, or the same MAC CE message, or the same DCI.

[0163] In some embodiments, the terminal determines that the first data needs to be transmitted preferentially in the case that the first information indicates that the terminal 101 is allowed to perform data transmission preferentially on the first data in the first time unit, and the second information indicates that the terminal 101 performs data transmission preferentially on the first data in the first time unit. In this case, the first time unit is further used for the terminal to perform data transmission and / or not to perform measurement.

[0164] It should be noted that in some embodiments, the step S201 and / or the step S202 can be omitted, and in this case, the terminal can be set by default to determine that the first data needs to be transmitted preferentially. Alternatively, the terminal can also determine whether the first data needs to be transmitted preferentially based on its own implementation.

[0165] In step S203, the terminal 101 determines to perform data transmission preferentially in the first time unit.

[0166] In some embodiments, the first time unit is further used for the terminal to perform data transmission and / or not to perform measurement in the case that the first data needs to be transmitted preferentially.

[0167] In some embodiments, the terminal can determine that the first data needs to be transmitted preferentially according to at least one of the first information and the second information. In an embodiment, the terminal determines to perform data transmission in the first time unit in the case that the first data needs to be transmitted preferentially.

[0168] In some embodiments, the first data needs to be transmitted preferentially can be understood as one of the following: the first information indicates that the terminal 101 is allowed to perform data transmission preferentially on the first data in the first time unit, and the second information indicates that the terminal 101 performs data transmission preferentially on the first data in the first time unit.

[0169] In some embodiments, the terminal 101 can determine to transmit the first data preferentially on the first logical channel in the first time unit. In this case, the first time unit is used for the terminal to perform transmission of the first data, and not to perform measurement.

[0170] In some embodiments, the first logical channel can include one or more logical channels. In some embodiments, the first logical channel can include a logical channel group.

[0171] In some embodiments, the first logical channel can include at least one of the following: a logical channel on which the terminal detects the first data, a logical channel on which data to be transmitted has triggered a first operation, and a logical channel on which the first data is contained in data to be transmitted.

[0172] In some embodiments, the first logical channel can be a logical channel carrying the first data. In some embodiments, the logical channel on which the terminal detects the first data can be the first logical channel.

[0173] In some embodiments, the first data can be all data carried on the first logical channel. In an example, the first logical channel can only carry the first data. In an example, all data to be transmitted on the first logical channel can be the first data.

[0174] In some embodiments, the first data can be part of data carried on the first logical channel. In an example, the first logical channel can carry the first data and other data. In an example, part of data to be transmitted on the first logical channel can be the first data.

[0175] In some embodiments, the first logical channel can be a logical channel on which all data is the first data and triggers the first operation. In some embodiments, the first operation can be an operation related to delay. In an example, the first operation can be delay status reporting (DSR). In this case, the first logical channel can be a logical channel triggering DSR.

[0176] In some embodiments, in a case where all data to be transmitted on the first logical channel is the first data, the terminal 101 can determine to preferentially transmit data in the first logical channel. In some embodiments, in a case where all data to be transmitted on the first logical channel is the first data, the terminal 101 can determine to preferentially transmit data in the first logical channel.

[0177] In some embodiments, in a case where part of data to be transmitted on the first logical channel is the first data, the terminal 101 can determine to preferentially transmit the first data in the first logical channel.

[0178] In some embodiments, the terminal 101 can determine to preferentially perform data transmission according to the first information and / or the second information.

[0179] In some embodiments, in a case where both step S201 and step S202 are performed, the terminal 101 can determine to preferentially perform data transmission according to the first information and the second information. In an example, the terminal 101 can determine to allow preferential performance of data transmission within the first time unit according to the first information; and then, the terminal 101 can determine to preferentially perform data transmission within the first time unit according to the second information. In this case, the terminal 101 can preferentially transmit the first data on the first logical channel within the first time unit upon detecting the first data.

[0180] In some embodiments, in the case where step S202 is omitted, the terminal 101 can determine to preferentially perform data transmission according to the first information and the protocol agreement. In an example, the terminal 101 can determine to allow preferential performance of data transmission in the first time unit according to the first information, and then determine to preferentially perform data transmission in the first time unit according to the protocol agreement. In this case, the terminal 101 can preferentially transmit the first data on the first logical channel in the first time unit upon detecting the first data.

[0181] In step S204, the terminal 101 transmits the first data to the network device 102 in the first time unit.

[0182] In some embodiments, the terminal 101 can preferentially perform data transmission on the first data in the first time unit.

[0183] In some embodiments, the first data can be uplink data. In some embodiments, the terminal 101 can preferentially perform data transmission on the first data in the first time unit, so as to send the first data to the network device 102.

[0237] In the following, the technical solutions of the embodiments of the present disclosure are exemplarily described through specific embodiments.

[0238] In some embodiments, the network (such as the network device 102) issues or protocols the terminal (such as the terminal 101) to use a specific data priority transmission strategy in a first time period.

[0239] In some embodiments, the first time period is a scheduling limited time period: that is, the terminal cannot perform data transmission and reception in this time period; usually because the terminal needs to perform measurement.

[0240] In some embodiments, the first time period can be a measurement gap (Measurement GAP).

[0241] In some embodiments, the first time period can be an SMTC window.

[0242] In some embodiments, the specific type of data is data with specific scheduling requirements; for example, delay critical data.

[0243] In some embodiments, the specific type of data can be data with a remaining time less than or equal to a threshold.

[0244] In some embodiments, the specific type of data can be data whose scheduling has lagged and cannot meet the multi-stream synchronization threshold between data streams.

[0245] In some embodiments, the specific data prioritized transmission can be detected in a certain logical channel or logical channel group.

[0246] In some embodiments, the specific data prioritized transmission includes prioritizing the transmission of a logical channel that detects a specific type of data or triggers a specific operation (e.g., DSR trigger) or prioritizing the transmission of data with a specific type within a logical channel.

[0247] In some embodiments, the terminal can use the specific data prioritized transmission strategy in the first time period upon receiving the network instruction.

[0248] In some embodiments, the network instruction includes an instruction (i.e., first information) that the network instructs the terminal to perform data transmission and reception in the first time period. In an example, the network can explicitly or implicitly indicate that the terminal can perform data transmission and reception in the first time period. For example, the network can explicitly indicate that the terminal can perform data transmission and reception in the first time period, or the network can implicitly indicate that the terminal deactivates or deconfigures the measurement interval. In this way, the network implicitly indicates that the terminal can perform data transmission and reception at this time because the measurement interval is invalid at this time.

[0249] In some embodiments, the network instruction can be an RRC message or a MAC CE message or a DCI.

[0250] In some embodiments, the MAC CE message can be a measurement interval deactivation, and thereafter, the terminal can perform data transmission and reception in the time period of the original measurement interval, and then use the specific data prioritized transmission strategy when sending uplink data.

[0251] In some embodiments, the network DCI instruction indicates that the terminal can perform data transmission and reception in the first time period or instructs the terminal to deactivate or deconfigure the measurement interval, i.e., data transmission and reception is prioritized over measurement, and thereafter, the terminal can perform data transmission and reception in the time period of the original measurement interval, and then use the specific data prioritized transmission strategy when sending uplink data.

[0252] In some embodiments, the terminal can determine whether to use the specific data prioritized transmission strategy in the first time period based on the information carried in the network instruction upon receiving the network instruction.

[0253] In some embodiments, the network instruction includes an instruction that the network instructs the terminal to perform data transmission and reception in the first time period or instructs the terminal to deactivate or deconfigure the measurement interval, and at the same time, the network also carries an indication that indicates whether the terminal uses the specific data prioritized transmission strategy in the first time period (i.e., second information).

[0254] In some embodiments, the network instruction can be an RRC message or a MAC CE message or a DCI.

[0255] In some embodiments, the MAC CE message can be a measurement interval deactivation, after which the terminal can perform data transmission and reception in the time period of the original measurement interval, and the MAC CE also carries an indication of whether to use a specific data priority transmission strategy. If yes, the terminal uses the specific data priority transmission strategy when sending uplink data.

[0256] In some embodiments, the network DCI instruction indicates that the terminal can perform data transmission and reception in the first time period or tells the terminal to deactivate or deconfigure the measurement interval, i.e., data transmission and reception is prioritized over measurement, and the DCI also carries an indication of whether to use a specific data priority transmission strategy. If yes, the terminal uses the specific data priority transmission strategy when sending uplink data.
