[0135] In some embodiments, for the uplink direction, the terminal can report the amount of data arriving in the uplink (Buffer size) to the base station, but the base station does not know how long it will take for the next data burst to arrive after the terminal sends a data packet in the uplink direction. If the base station can know the duration information of the next data burst arrival in advance, the base station can put the terminal into a dormant state during the time when there is no burst in the middle. Therefore, the introduction of this parameter is beneficial to power saving of the terminal in the uplink direction.

[0136] Figure 2 FIG. 1 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. Figure 2 As shown, the embodiment of the present disclosure relates to a communication method, which is used in a communication system 100, and the method includes:

[0137] Step S2101: The terminal sends third information to the network device.

[0138] In some embodiments, the network device receives third information sent by the terminal.

[0139] In some embodiments, the third information is used to indicate that the terminal supports sending the first information to the network device. The third information may also be referred to as capability information, which is not limited here.

[0140] In some embodiments, the terminal may send the third information to the network device when the terminal establishes a connection with the network device.

[0141] In some embodiments, the first information is used to indicate at least one of the following: a first time, a second time, wherein the first time is the time when the first data packet is sent, and the first data packet is the data packet being sent; the second time is the time when the second data packet is sent, and the second data packet is the next data packet to be sent.

[0142] It should be noted that the time of sending a data packet corresponds to the time when a receiving end receives the data packet or the time when the data packet arrives at the receiving end.

[0143] In some embodiments, the first time is the duration or duration range of sending the first data packet. For example, the duration may be 10 seconds; or the duration range is 10.1 to 10.9 seconds.

[0144] In some embodiments, the second time is the duration or duration range required to wait for sending the second data packet. Here, the duration required to wait can be understood as the interval between the current time and the time when the data packet before sending the second data packet is completed. For example, if the first data packet is currently being sent, the duration required to wait is the interval between the current time and the time when the first data packet is completed.

[0145] In some embodiments, the first information is used by the network device to determine the time to make the terminal enter the sleep state.

[0146] In some embodiments, the first data packet may be a single data packet or a burst of data packets, which is not limited here.

[0147] In some embodiments, the second data packet may be a single data packet or a burst of data packets, which is not limited here.

[0148] In some embodiments, the time may be a start time and an end time.

[0149] In some embodiments, the time may be a start time and a duration.

[0150] In some embodiments, the time may be a duration and an end time.

[0151] Step S2102: The terminal sends first information to the network device.

[0152] In some embodiments, the network device receives first information sent by the terminal.

[0153] In some embodiments, the terminal sends the first information to the network device based on a first period. The first period may be 1 millisecond or 1 second.

[0154] In some embodiments, the terminal sends a first message to the network device. The first message includes first information; the first message is at least one of the following: a media access control (MAC) control element (CE) message; a radio resource control (RRC) message.

[0155] In some embodiments, based on a first condition, the terminal sends the first information to the network device. The first condition is at least one of the following: the first time and / or the second time is updated;

[0156] The data volume of the cache data reported based on the buffer state report (BSR) is the first data volume;

[0157] The data volume of the cached data reported based on the Delay State Report (DSR) is the second data volume.

[0158] Exemplarily, when the first time and / or the second time in the first information sent last time is updated, the terminal sends the first information to the network device.

[0159] Exemplarily, when the amount of buffered data reported by the BSR is less than the first quantity threshold, the terminal sends the first information to the network device. For example, when the amount of data is less than 5, the terminal sends the first information to the network device.

[0160] Exemplarily, when the amount of cached data reported by the DSR is less than the second quantity threshold, the terminal sends the first information to the network device. For example, when the amount of data is less than 3, the terminal sends the first information to the network device.

[0161] Exemplarily, when the amount of cached data reported by the BSR is 0, the terminal sends the first information to the network device.

[0162] Exemplarily, when the amount of cached data reported by the DSR is 0, the terminal sends the first information to the network device.

[0163] Exemplarily, when the amount of cached data reported by the BSR or DSR is 0, the terminal sends the first information (eg, the second time) to the network device.

[0164] Here, the amount of buffered data is the buffer size of the BSR or DSR, for example, buffer size=0.

[0165] In some embodiments, the first information includes time information. The time information is used to determine the first time and / or the second time; the time information includes: the number of time units and / or index values.

[0166] In some embodiments, there is a first mapping relationship between the index value and the duration, and there is a second mapping relationship between the index value and the duration range.

[0167] For example, the number of time units is x time units, and the corresponding duration is 10xms, that is, the first mapping relationship is the relationship between x and 10x.

[0168] For example, when the index value of index is index0, the corresponding duration range is the first duration range, and when the index value of index is index1, the corresponding duration range is the second duration range. That is, the second mapping relationship is the relationship between index0 and the first duration range and between index1 and the second duration range.

[0169] In the above embodiment, if the time information includes the number of time units (for example, 3) and the duration of the time unit is 1 ms, the determined first time and / or second time is 3 ms. In this way, the first time and / or second time can be clearly determined.

[0170] In the above embodiment, if the time information includes an index value, since there is a first mapping relationship between the index value and the duration or a second mapping relationship between the index value and the duration range, the duration corresponding to the first time and / or the second time can be clearly determined based on the indicated index value and the first mapping relationship or the second mapping relationship, or the duration range corresponding to the first time and / or the second time can be clearly determined.

[0171] In some embodiments, the first information is information sent to the network device for a first quality of service (Qos) flow.

[0172] In some embodiments, first information is sent to a network device for a single Quality of Service (Qos) flow.

[0173] In some embodiments, the first data packet and / or the second data packet are data packets associated with a QoS flow.

[0174] In some embodiments, the first information is further used to indicate a first QoS flow.

[0175] In some embodiments, the first QoS flow can be indicated by a first identifier (different QoS flows can be associated with different identifiers). For example, if the first information is information sent to the network device for the first QoS flow, the first information includes a first identifier, so that the network device can clearly determine the first QoS flow based on the first identifier after receiving the first information.

[0176] In some embodiments, the first information may include a single identifier, which is used to indicate a single QoS flow that has a mapping relationship with the identifier, such as the first QoS flow, so that the network device can clearly determine the single QoS flow based on the identifier after receiving the first information.

[0177] In some embodiments, the first information may include multiple identifiers, each of the multiple identifiers is used to indicate a single QoS flow that has a mapping relationship with the identifier, such as a first QoS flow. In this way, multiple QoS flows can be indicated by multiple identifiers, so that the network device can clearly determine the multiple QoS flows based on the multiple identifiers after receiving the first information.

[0178] In some embodiments, the first information is information sent to the network device for a first logical channel LCH; wherein the first LCH is used to send at least one QoS flow.

[0179] In some embodiments, the first information is sent to the network device for a single logical channel (LCH).

[0180] In some embodiments, the LCH is used to send at least one QoS flow.

[0181] In some embodiments, the first data packet and / or the second data packet are data packets of at least one QoS flow.

[0182] In some embodiments, the first information is further used to indicate the first LCH.

[0183] In some embodiments, the first LCH can be indicated by a second identifier (different LCHs can be associated with different identifiers). For example, if the first information is information sent to the network device for the first LCH, the first information includes the second identifier, so that the network device can clearly determine the first LCH based on the second identifier after receiving the first information.

[0184] In some embodiments, the first information may include a single identifier, which is used to indicate a single LCH that has a mapping relationship with the identifier, such as the first LCH, so that the network device can clearly determine the single LCH based on the identifier after receiving the first information.

[0185] In some embodiments, the first information may include multiple identifiers, each of the multiple identifiers is used to indicate a single LCH that has a mapping relationship with the identifier, such as the first LCH. In this way, multiple LCHs can be indicated by multiple identifiers, so that the network device can clearly determine the multiple LCHs based on the multiple identifiers after receiving the first information.

[0186] In some embodiments, the first information is information sent to the network device for a first logical channel group LCG; wherein the first LCG includes at least one LCH.

[0187] In some embodiments, the first information is sent to the network device for a single logical channel group (LCG).

[0188] In some embodiments, the LCG includes at least one LCH.

[0189] In some embodiments, the first data packet and / or the second data packet is a data packet sent in at least one LCH.

[0190] In some embodiments, the LCH is used to send at least one QoS flow, and the first data packet and / or the second data packet are data packets of at least one QoS flow sent in at least one LCH.

[0191] In some embodiments, the first information is further used to indicate the first LCG.

[0192] In some embodiments, the first LCG can be indicated by a third identifier (different LCGs can be associated with different identifiers). For example, if the first information is information sent to the network device for the first LCG, the first information includes a third identifier, so that the network device can clearly determine the first LCG based on the third identifier after receiving the first information.

[0193] In some embodiments, the first information may include a single identifier, which is used to indicate a single LCG that has a mapping relationship with the identifier, such as the first LCG, so that the network device can clearly determine the single LCG based on the identifier after receiving the first information.

[0194] In some embodiments, the first information may include multiple identifiers, each of the multiple identifiers is used to indicate a single LCG that has a mapping relationship with the identifier, such as the first LCG. In this way, multiple LCGs can be indicated by multiple identifiers, so that the network device can clearly determine the multiple LCGs based on the multiple identifiers after receiving the first information.

[0195] Step S2103: The terminal sends second information to the network device.

[0196] In some embodiments, the network device receives second information sent by the terminal.

[0197] In some embodiments, the second information is a buffer status report BSR.

[0198] In some embodiments, the first information is used to indicate the second time, and the second information is used to indicate the first cache value and / or the second cache value.

[0199] In some embodiments, the first buffer value is used to indicate a total amount of first data packets to be sent.

[0200] In some embodiments, based on the total amount of first data packets to be sent indicated by the first cache value, the network device can determine the time when the first data packet is completely sent. For example, when the first cache value is x, it is determined that x data packets need to be sent before the first data packet is completely sent; when the first cache value is 0, it is determined that the first data packet is completely sent.

[0201] In some embodiments, the second buffer value is used to indicate the amount of first data packets to be sent within a unit time.

[0202] In some embodiments, based on the amount of first data packets to be sent per unit time indicated by the second cache value (e.g., z), the network device can determine how many first data packets need to be received within the first time, thereby confirming that the first data packets have been sent after receiving a certain number of first data packets.

[0203] In some embodiments, the terminal sends the second information to the network device while sending the first information to the network device.

[0204] In some embodiments, step S2103 is a non-essential step. When the network device performs an operation based on the first information in step S2104, step S2103 is a non-essential step. When the network device performs an operation based on the first information and the second information in step S2104, step S2103 is a required step.

[0205] Step S2104: The network device performs an operation.

[0206] In some embodiments, when the network device receives the first information and / or the second information, an operation is performed based on the first information, or based on the first information and the second information.

[0207] In some embodiments, the operation performed by the network device may be an operation associated with controlling the terminal to enter a sleep state.

[0208] In some embodiments, the operation associated with controlling the terminal to enter a dormant state may include at least one of the following:

[0209] Determine the time when the terminal enters a dormant state;

[0210] Sending information to the terminal for causing the terminal to enter sleep mode. In some embodiments, the network device performs an operation based on the first information. (This is an embodiment that does not rely on the second information in step S2103)

[0211] In some embodiments, the network device determines the time for the terminal to enter a sleep state based on the first information; when the current time is the time for the terminal to enter a sleep state determined based on the first information, information for causing the terminal to enter a sleep state is sent to the terminal; after receiving the information, the terminal can enter a sleep state, thereby achieving the purpose of saving power for the terminal.

[0212] Exemplarily, the interval between the time when the first data packet is sent based on the first time and the time when the second data packet is to be sent based on the second time is determined by the network device to be the time for the terminal to enter the sleep state; when the current time is within the interval, information for causing the terminal to enter the sleep state is sent to the terminal; after receiving the information, the terminal can enter the sleep state, thereby achieving the purpose of saving power for the terminal.

[0213] In some embodiments, the information used to cause the terminal to enter a sleep state may include time information, which is used to indicate the duration for the terminal to enter a sleep state. The duration may be less than or equal to the duration determined by the network device based on the first time and the second time, and is not limited here.

[0214] In some embodiments, the network device performs an operation based on the first information and the second information. (This is an embodiment that relies on the second information in step S2103)

[0215] In some embodiments, the network device determines the time for the terminal to enter a sleep state based on first information and second information; when the current time is the time for the terminal to enter a sleep state determined based on the first information and the second information, information for causing the terminal to enter a sleep state is sent to the terminal; after receiving the information, the terminal can enter a sleep state, thereby achieving the purpose of saving power for the terminal.

[0216] Exemplarily, the network device determines the time when the first data packet is sent based on the second information (for example, the second information indicates that the first cache value in the BSR is 0, that is, the first data packet is sent) and the interval time between the times of the second data packets to be sent determined based on the second time is the time for the terminal to enter a sleep state; when the current time is within the interval time, information for causing the terminal to enter a sleep state is sent to the terminal; after receiving the information, the terminal can enter a sleep state, thereby achieving the purpose of saving power for the terminal.

[0217] Exemplarily, the network device determines the time when the first data packet is sent based on the second information and the first time (for example, the second information indicates that the second cache value in the BSR is 3, and the first time is 4s, that is, the first data packet needs to be sent after 12 first data packets are sent) and the interval time between the times of the second data packets to be sent based on the second time is the time for the terminal to enter a sleep state; when the current time is within the interval time, information for causing the terminal to enter a sleep state is sent to the terminal; after receiving the information, the terminal can enter a sleep state, thereby achieving the purpose of saving power for the terminal.

[0324] In some embodiments, the above method may include the methods of the above network device side and terminal side embodiments, which will not be repeated here.

[0325] In order to better understand the embodiments of the present disclosure, some exemplary embodiments are further described below:

[0326] In some embodiments, a method for protecting a terminal reporting data packet (corresponding to a first data packet or a second data packet) reaching auxiliary information (corresponding to the first information) is provided.

[0327] In some embodiments, the auxiliary information includes a time interval (corresponding to the second time) for the next data packet (including a single data packet and / or a data packet burst, corresponding to the second data packet) to arrive.

[0328] In some embodiments, the auxiliary information includes the arrival duration (corresponding to the first time) of the current data packet (including a single data packet and / or a data packet burst, corresponding to the first data packet).

[0329] In some embodiments, the reporting granularity may be a time unit such as ms or s (corresponding to the first period).

[0330] In some embodiments, the reporting method includes reporting via MAC CE, RRC and other signaling (corresponding to the first message).

[0331] In some embodiments, time information is carried therein;

[0332] In some embodiments, the time information may be provided explicitly, such as x time units, such as x ms.

[0333] In some embodiments, the time information may be provided implicitly, for example, index 0 indicates that the range is in the first interval; index 1 indicates that the range is in the second interval.

[0334] In some embodiments, the reporting granularity is each QoS Flow.

[0335] In some embodiments, the reporting information (corresponding to the first information) indicates for which QoS flow the report is being made.

[0336] In some embodiments, the reporting granularity is per LCH.

[0337] In some embodiments, the reporting information (corresponding to the first information) indicates which LCH the report is for.

[0338] In some embodiments, the reporting granularity is for each LCH; wherein the auxiliary information is determined by the information of all QoS flows mapped to the logical channel, for example, if the auxiliary information indicates the time interval for the arrival of the next data packet (including a single data packet and / or a data packet burst), then the time interval for the arrival of the next data packet (including a single data packet and / or a data packet burst) for the LCH is determined by the minimum or maximum time interval for the arrival of the next data packet (including a single data packet and / or a data packet burst) on all QoS flows mapped to the LCH.

[0339] In some embodiments, the reporting granularity is per LCG.

[0340] In some embodiments, the reporting information indicates which LCG the report is for.

[0341] In some embodiments, the reporting granularity is for each LCG; wherein the auxiliary information is determined by the information of the logical channel LCH mapped to the LCG. For example, if the auxiliary information indicates the time interval for the arrival of the next data packet (including a single data packet / or a data packet burst), it is determined by the time mapped to the logical channel LCH of the LCG. For example, the time interval for the arrival of the next data packet (including a single data packet / or a data packet burst) is the minimum or maximum time interval for the arrival of the next data packet (including a single data packet / or a data packet burst) on all logical channels for the LCG.

[0342] In some embodiments, the reporting granularity is for each LCG; the auxiliary information is determined by the information of all Qos flows of the logical channel LCH mapped to the LCG. For example, if the auxiliary information indicates the time interval for the arrival of the next data packet (including a single data packet / or a data packet burst), the time is determined by the time information of all Qos flows mapped to all logical channels. For example, the time interval for the arrival of the next data packet (including a single data packet / or a data packet burst) for the LCG is the minimum or maximum time interval for the arrival of the next data packet (including a single data packet / or a data packet burst) of all Qos flows of all logical channels;

[0343] The arrival duration (corresponding to the first time) of the current data packet (including a single data packet and / or a data packet burst, corresponding to the first data packet) may also be determined in a similar manner.

[0344] In some embodiments, the reporting granularity is for each LCH; wherein the auxiliary information is determined by the information of all Qos flows mapped to the logical channel, for example, if the auxiliary information indicates the duration of the arrival of the next data packet (including a single data packet and / or a data packet burst), then the duration of the arrival of the next data packet (including a single data packet and / or a data packet burst) for the LCH is determined by the minimum or maximum duration of the arrival of the next data packet (including a single data packet and / or a data packet burst) on all Qos flows mapped to the LCH.

[0345] In some embodiments, the reporting granularity is for each LCG; the auxiliary information is determined by the information of all Qos flows of the logical channel LCH mapped to the LCG. For example, if the auxiliary information indicates the duration of the arrival of the next data packet (including a single data packet / or a data packet burst), the time is determined by the time information of all Qos flows mapped to all logical channels. For example, the duration of the arrival of the next data packet (including a single data packet / or a data packet burst) for the LCG is the minimum or maximum duration of the arrival of the next data packet (including a single data packet / or a data packet burst) of all Qos flows of all logical channels, etc.;

[0346] In some embodiments, when the UE reports the auxiliary information that the data packet arrives, a BSR report or the like may be triggered (corresponding to sending the second information).

[0347] In some embodiments, if the time interval for reporting the arrival of the next data packet (including a single data packet / or a data packet burst) is triggered, a BSR report can be triggered, where the buffer size in the BSR is 0. (That is, after the transmission of the current data burst is completed, how long will it take for the next transmission to start)

[0348] In some embodiments, if the arrival duration of the next data packet (including a single data packet and / or a data packet burst) is reported, a BSR report may be triggered, wherein the buffer size in the BSR is y; (i.e., the estimated total buffer size when the packet of the duration arrives) or a BSR report may be triggered, wherein the buffer size in the BSR is z; (i.e., the average buffer size per time unit within the duration)

[0349] In some embodiments, a new UE capability is introduced, which supports the capability of reporting data packet arrival auxiliary information (corresponding to the third information).

[0350] In some embodiments, the network may configure the triggering condition of the auxiliary information.

[0351] In some embodiments, reporting is performed only when there is a change between the reported information and the last reported information (ie, to reduce frequent reporting).

[0352] In some embodiments, the reporting of the time interval for the arrival of the next data packet (including a single data packet and / or a data packet burst) is allowed only when the BSR or DSR reports buffer size=0.
