[0137] FIG. 2 is an interaction diagram illustrating a communication method according to an embodiment of the present disclosure. As shown in FIG. 2, the embodiment of the present disclosure relates to a communication method, for a communication system 100, the method comprising:

[0138] Step S2101: The terminal sends third information to the network device.

[0139] In some embodiments, the network device receives the third information sent by the terminal.

[0140] 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 can also be referred to as capability information, which is not limited herein.

[0141] In some embodiments, the terminal can send the third information to the network device when the terminal establishes a connection with the network device.

[0142] In some embodiments, the first information is used to indicate at least one of the following: the first time, the second time. The first time is the time of sending the first data packet, and the first data packet is the data packet being sent; the second time is the time of sending the second data packet, and the second data packet is the next data packet to be sent.

[0143] It should be noted that the time of sending the data packet corresponds to the time of receiving by a receiving end or the time of arrival of the data packet at the receiving end.

[0144] In some embodiments, the first time is the time length or time length range of sending the first data packet. For example, the time length can be 10 seconds; or the time length range is 10.1 to 10.9 seconds.

[0145] In some embodiments, the second time is a time length or a time length range that needs to be waited for sending the second data packet. Here, the time length that needs to be waited for can be understood as an interval time length between the current time and the time when the data packet is finished before the second data packet is sent. For example, the first data packet is being sent at present, and the time length that needs to be waited for is an interval time length between the current time and the time when the first data packet is finished.

[0146] In some embodiments, the first information is used by the network device to determine the time for the terminal to enter the sleep state.

[0147] In some embodiments, the first data packet can be a single data packet or a burst of data packets, which is not limited herein.

[0148] In some embodiments, the second data packet can be a single data packet or a burst of data packets, which is not limited herein.

[0149] In some embodiments, the time can be a start time and an end time.

[0150] In some embodiments, the time can be a start time and a time length.

[0151] In some embodiments, the time can be a time length and an end time.

[0152] Step S2102: The terminal sends first information to the network device.

[0153] In some embodiments, the network device receives the first information sent by the terminal.

[0154] In some embodiments, the terminal sends the first information to the network device based on a first period. The first period can be 1 millisecond or 1 second.

[0155] In some embodiments, the terminal sends a first message to the network device. The first message includes the first information; and the first message is at least one of the following: a media access control (MAC) control element (CE) message; and a radio resource control (RRC) message.

[0156] 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;

[0157] The data amount of the buffer data reported by the buffer state report (BSR) is a first data amount;

[0158] The data amount of the buffer data reported based on the delay state report (DSR) is a second data amount.

[0159] Exemplarily, in a case where the first time and / or the second time in the first information last sent is updated, the terminal sends the first information to the network device.

[0160] Exemplarily, in a case where the data amount of the buffer data reported by the BSR is less than a first quantity threshold, the terminal sends the first information to the network device. For example, in a case where the data amount is less than 5, the terminal sends the first information to the network device.

[0161] Exemplarily, in a case where the data amount of the buffer data reported by the DSR is less than a second quantity threshold, the terminal sends the first information to the network device. For example, in a case where the data amount is less than 3, the terminal sends the first information to the network device.

[0162] Exemplarily, in a case where the data amount of the buffer data reported by the BSR is 0, the terminal sends the first information to the network device.

[0163] Exemplarily, in a case where the data amount of the buffer data reported by the DSR is 0, the terminal sends the first information to the network device.

[0164] Exemplarily, in a case where the data amount of the buffer data reported by the BSR or the DSR is 0, the terminal sends the first information (e.g., the second time) to the network device.

[0165] Here, the data amount of the buffer data is the buffer size of the BSR or the DSR, for example, buffer size = 0.

[0166] 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: a quantity of time units and / or an index value.

[0167] In some embodiments, there is a first mapping relationship between the index value and the time length, and a second mapping relationship between the index value and the time length range.

[0168] For example, the quantity of time units is x time units, and the corresponding time length is 10x ms, i.e., the first mapping relationship is the relationship between x and 10x.

[0169] For example, when the index value of the index index is index0, the corresponding time length range is the first time length range, and when the index value of the index index is index1, the corresponding time length range is the second time length range. That is, the second mapping relationship is the relationship between index0 and the first time length range and the relationship between index1 and the second time length range.

[0170] In the above embodiment, if the time information includes the number of time units (for example, 3) and the time length of the time unit is 1 ms, the determined first time and / or second time is 3 ms, so that the first time and / or the second time can be determined.

[0171] In the above embodiment, if the time information includes an index value, because there is a first mapping relationship between the index value and the time length or a second mapping relationship between the index value and the time length range, the time length corresponding to the first time and / or the second time or the time length range corresponding to the first time and / or the second time can be determined based on the indicated index value and the first mapping relationship or the second mapping relationship.

[0172] In some embodiments, the first information is information sent to the network device for a first quality of service (Qos) flow.

[0175] In some embodiments, the first information is also used to indicate the first Qos flow.

[0176] 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 the first identifier, so that the network device can determine the first Qos flow based on the first identifier after receiving the first information.

[0177] In some embodiments, the first information can include a single identifier, and the single identifier is used to indicate a single Qos flow, for example, the first Qos flow, so that the network device can determine the single Qos flow based on the identifier after receiving the first information.

[0178] In some embodiments, the first information can include a plurality of identifiers, and each identifier in the plurality of identifiers is used to indicate a single Qos flow, for example, the first Qos flow, so that a plurality of Qos flows can be indicated by the plurality of identifiers, and the network device can determine the plurality of Qos flows based on the plurality of identifiers after receiving the first information.

[0179] 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.

[0183] In some embodiments, the first information is further used to indicate the first LCH.

[0184] 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 determine the first LCH based on the second identifier after receiving the first information.

[0185] In some embodiments, the first information can include a single identifier, and the single identifier is used to indicate a single LCH, such as the first LCH, which has a mapping relationship with the identifier, so that the network device can determine the single LCH based on the identifier after receiving the first information.

[0186] In some embodiments, the first information can include multiple identifiers, and each identifier in the multiple identifiers is used to indicate a single LCH, such as the first LCH, which has a mapping relationship with the identifier, so that multiple LCHs can be indicated by the multiple identifiers, so that the network device can determine the multiple LCHs based on the multiple identifiers after receiving the first information.

[0187] 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.

[0188] In some embodiments, the first information is sent to the network device for a single logical channel group (LCG).

[0189] In some embodiments, the LCG includes at least one LCH.

[0190] In some embodiments, the first data packet and / or the second data packet is a data packet sent in the at least one LCH.

[0191] 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 the at least one Qos flow sent in the at least one LCH.

[0192] In some embodiments, the first information is further used to indicate the first LCG.

[0193] 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 by the terminal to the network device for the first LCG, the first information includes the third identifier, so that the network device can determine the first LCG based on the third identifier after receiving the first information.

[0194] In some embodiments, the first information can include a single identifier, and the single identifier is used to indicate a single LCG, for example, the first LCG, which has a mapping relationship with the identifier, so that the network device can determine the single LCG based on the identifier after receiving the first information.

[0195] In some embodiments, the first information can include a plurality of identifiers, and each identifier in the plurality of identifiers is used to indicate a single LCG, for example, the first LCG, which has a mapping relationship with the identifier, so that a plurality of LCGs can be indicated by the plurality of identifiers, so that the network device can determine the plurality of LCGs based on the plurality of identifiers after receiving the first information.

[0196] Step S2103: The terminal sends second information to the network device.

[0197] In some embodiments, the network device receives the second information sent by the terminal.

[0198] In some embodiments, the second information is a buffer status report (BSR).

[0199] In some embodiments, the first information is used to indicate the second time, and the second information is used to indicate the first buffer value and / or the second buffer value.

[0200] In some embodiments, the first buffer value is used to indicate the total amount of the first data packets to be sent.

[0201] In some embodiments, based on the total amount of the first data packets to be sent indicated by the first buffer value, the network device can determine the time when the first data packets are sent completely, for example, when the first buffer value is x, it is determined that the first data packets are sent completely after x data packets are sent; when the first buffer value is 0, it is determined that the first data packets are sent completely.

[0202] In some embodiments, the second buffer value is used to indicate the amount of the first data packets to be sent in a unit of time.

[0203] In some embodiments, based on the amount of first data packets indicated by the second cache value to be sent in a unit of time (e.g., z), the network device can determine how many first data packets are still needed to be received in the first time, thereby confirming that the first data packet sending is completed after how many first data packets are received.

[0204] In some embodiments, the terminal sends the second information to the network device at the same time when the first information is sent to the network device.

[0205] In some embodiments, step S2103 is an optional step. When the network device performs the operation based on the first information in step S2104, step S2103 is an optional step. When the network device performs the operation based on the first information and the second information in step S2104, step S2103 is a necessary step.

[0206] Step S2104: The network device performs the operation.

[0207] In some embodiments, when the network device receives the first information and / or the second information, the operation is performed based on the first information or based on the first information and the second information.

[0208] In some embodiments, the operation performed by the network device can be an operation associated with controlling the terminal to enter the sleep state.

[0209] In some embodiments, the operation associated with controlling the terminal to enter the sleep state can include at least one of the following:

[0210] Determining the time for the terminal to enter the sleep state;

[0211] Sending information to the terminal for making the terminal enter the sleep state. In some embodiments, the network device performs the operation based on the first information. (This is an embodiment not dependent on the second information in step S2103)

[0212] In some embodiments, the network device determines the time for the terminal to enter the sleep state based on the first information; when the current time is the time for the terminal to enter the sleep state determined based on the first information, the network device sends information to the terminal for making the terminal enter the sleep state; after receiving the information, the terminal can enter the sleep state, thus achieving the purpose of power saving of the terminal.

[0213] For example, the interval time between the time determined by the network device based on the first time when the sending of the first data packet is completed and the time determined by the network device based on the second time when the second data packet is to be sent is the time for the terminal to enter the sleep state; when the current time is within the interval time, the network device sends information to the terminal for making the terminal enter the sleep state; after receiving the information, the terminal can enter the sleep state, thus achieving the purpose of power saving of the terminal.

[0214] In some embodiments, the information for the terminal to enter the sleep state can comprise time information indicating a time length for the terminal to enter the sleep state, which can be less than or equal to the time length determined by the network device based on the first time and the second time, without limitation.

[0215] In some embodiments, the network device performs an operation based on the first information and the second information. (This is an embodiment relying on the second information in step S2103)

[0216] In some embodiments, the network device determines a time for the terminal to enter the sleep state based on the first information and the second information; when the current time is the time for the terminal to enter the sleep state determined based on the first information and the second information, the network device sends information for the terminal to enter the sleep state to the terminal; after receiving the information, the terminal can enter the sleep state, so that the purpose of power saving of the terminal can be achieved.

[0217] For example, the network device determines a time interval between the time when the first data packet is sent completely based on the second information (for example, the second information indicates that the first buffer value in the BSR is 0, that is, the first data packet is sent completely) and the time of the second data packet to be sent determined based on the second time as the time for the terminal to enter the sleep state; when the current time is within the time interval, the network device sends information for the terminal to enter the sleep state to the terminal; after receiving the information, the terminal can enter the sleep state, so that the purpose of power saving of the terminal can be achieved.

[0218] For example, the network device determines a time interval between the time when the first data packet is sent completely based on the second information (for example, the second information indicates that the first buffer value in the BSR is 0, that is, the first data packet is sent completely) and the time of the second data packet to be sent determined based on the second time as the time for the terminal to enter the sleep state; when the current time is within the time interval, the network device sends information for the terminal to enter the sleep state to the terminal; after receiving the information, the terminal can enter the sleep state, so that the purpose of power saving of the terminal can be achieved.

[0326] In order to better understand the embodiments of the present disclosure, the following will be further illustrated by some exemplary embodiments:

[0327] In some embodiments, a method for a terminal to report the arrival of a data packet (corresponding to the first data packet or the second data packet) to auxiliary information (corresponding to the first information) is protected.

[0328] In some embodiments, the auxiliary information includes the time interval (corresponding to the second time) of the arrival of the next data packet (including a single data packet or a data packet burst, corresponding to the second data packet).

[0329] 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 or a data packet burst, corresponding to the first data packet).

[0330] In some embodiments, the reporting granularity can be a time unit (corresponding to the first period) such as ms, s, etc.

[0331] In some embodiments, the reporting manner includes reporting (corresponding to the first message) by MAC CE, RRC, etc.

[0332] In some embodiments, the time information is carried.

[0333] In some embodiments, the time information can be explicitly provided, such as x time units, such as x ms.

[0334] In some embodiments, the time information can be implicitly provided, such as index 0 shows the range is in the first interval; index 1 shows the range is in the second interval.

[0335] In some embodiments, the reporting granularity is per Qos Flow.

[0336] In some embodiments, it is indicated in the reporting information (corresponding to the first information) which Qos flow the reporting is for.

[0337] In some embodiments, the reporting granularity is per LCH.

[0338] In some embodiments, it is indicated in the reporting information (corresponding to the first information) which LCH the reporting is for.

[0339] In some embodiments, the reporting granularity is per LCH; wherein the assistance information is determined by information of all Qos flows mapped to the logical channel; such as, if the assistance information indicates the time interval of the arrival of the next data packet (including single data packet / or data packet burst), then the time interval of the arrival of the next data packet (including single data packet / or data packet burst) for the LCH is the minimum value or maximum value, etc. of the time interval of the arrival of the next data packet (including single data packet / or data packet burst) on all Qos flows mapped to the LCH.

[0340] In some embodiments, the reporting granularity is per LCG.

[0341] In some embodiments, it is indicated in the reporting information which LCG the reporting is for.

[0342] In some embodiments, the reporting granularity is per LCG; wherein the assistance information is determined by information of logical channels LCHs mapped to the LCG. Such as, if the assistance information indicates the time interval of the arrival of the next data packet (including single data packet / or data packet burst), then the time interval of the arrival of the next data packet (including single data packet / or data packet burst) for the LCG is determined by the time on the logical channels LCHs mapped to the LCG, such as, the time interval of the arrival of the next data packet (including single data packet / or data packet burst) for the LCG is the minimum value or maximum value, etc. of the time interval of the arrival of the next data packet (including single data packet / or data packet burst) on all logical channels.

[0343] In some embodiments, the reporting granularity is per LCG; the assistance information is determined by information of all Qos flows of logical channels LCHs mapped to the LCG. For example, if the assistance information indicates the time interval of arrival of the next data packet (including a single data packet or a data packet burst), the time information of all Qos flows of all logical channels is determined, for example, the time interval of arrival of the next data packet (including a single data packet or a data packet burst) for the LCG is the minimum or maximum of the time interval of 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.

[0344] The arrival duration (corresponding to the first time) of the current data packet (including a single data packet or a data packet burst, corresponding to the first data packet) can also be determined in a similar manner.

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

[0346] In some embodiments, the reporting granularity is per LCG; the assistance information is determined by information of all Qos flows of logical channels LCHs mapped to the LCG. For example, if the assistance information indicates the duration of arrival of the next data packet (including a single data packet or a data packet burst), the time information of all Qos flows of all logical channels is determined, for example, the duration of arrival of the next data packet (including a single data packet or a data packet burst) for the LCG is the minimum or maximum of the duration of 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.

[0347] In some embodiments, when the UE reports the data packet arrival assistance information, the reporting of BSR or the like (corresponding to the sending of the second information) can be triggered.

[0348] In some embodiments, a BSR reporting can be triggered if the time interval of arrival of the next data packet (including a single data packet or a data packet burst) is reported, wherein the buffer size in the BSR = 0. (That is, the current data burst transmission is complete, and how long will the next transmission start)

[0349] In some embodiments, a BSR reporting can be triggered if the duration of arrival of the next data packet (including a single data packet or a data packet burst) is reported, wherein the buffer size in the BSR = y; (that is, the total buffer size estimated when the packet arrives in the duration) or a BSR reporting can be triggered, wherein the buffer size in the BSR = z; (that is, the average buffer size per time unit in the duration)

[0350] 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).

[0351] In some embodiments, the network can configure the trigger condition of the auxiliary information.

[0352] In some embodiments, the reporting information is reported only when there is a change from the last reporting (that is, to reduce frequent reporting).

[0353] In some embodiments, the time interval of arrival of the next data packet (including a single data packet or a data packet burst) is allowed to be reported only when the buffer size = 0 is reported in the BSR or DSR.
