Example 1

Embodiment 1 of the present application provides a method for updating system information, and the method can be executed by a network device.

FIG. 3 is a schematic diagram of the method for updating system information in this embodiment. As shown in FIG. 3, the method includes:

Step 301: The network device sends first indication information, where the first indication information is used to indicate to the terminal device the earliest modification period for acquiring or applying the updated system information (SI).

According to this embodiment, the terminal device is instructed to acquire or apply the earliest modification period of the updated system information (SI) through the first indication information, so that the terminal device can acquire or apply the updated system information according to the earliest modification period ( SI), so as to prevent the terminal equipment from using invalid system information. The advantage of this embodiment is that no additional paging opportunities are needed, time-frequency resources can be saved, and more resources are provided for user data transmission.

In this embodiment, as shown in FIG. 3, the method may further include:

Step 302: The network device sends an SI update instruction in at least one modification period.

In an embodiment, the network device may continuously send the SI update instruction in more than two modification cycles, thereby, the number of times the SI update instruction is sent can be increased, thereby avoiding the situation that some terminal devices cannot receive the SI update instruction. Wherein, the two or more modification cycles may be continuous modification cycles or discontinuous modification cycles.

In this embodiment, the first indication information may include: a first quantity. This first number can be expressed as x. Thus, the earliest modification period for obtaining or applying the updated system information (SI) indicated by the first indication information may be the last modification in the first number of modification periods after the modification period for which the SI update indication was sent. cycle. For example, the network device sends the SI update instruction in the modification period M, and the earliest modification period is the last modification period in x modification periods after the modification period M, that is, the modification period (M+x).

In the embodiments of the present application, the earliest modification period for obtaining or applying updated system information (SI) can also be referred to as the latest modification period, or the first system information that can be obtained or applied for update ( SI) modification cycle, etc.

In this embodiment, the first indication information may be sent through system information. For example, the first indication information may be carried in System Information Block 1 (SIB1: System Information Block 1) and sent together with the modification period coefficient (modificationPeriodCoeff).

In this embodiment, the first indication information may also be sent through Downlink Control Information (DCI). For example, the downlink control information is used to transmit an SI update indication, where the downlink control information can be scrambled using P-RNTI; or, the downlink control information is used to schedule a downlink channel for transmitting the updated SI, where the downlink control information Information is scrambled using SI-RNTI.

In an embodiment, the first indication information may be sent using the DCI format 1_0 scrambled by paging-radio network temporary identification (P-RNTI). Fig. 4 is a schematic diagram of using P-RNTI scrambled DCI format 1_0 to send the first indication information. Fig. 4 (a), (b), (c) shows three possible sending modes.

As shown in (a) of FIG. 4, the first indication information may be carried in the remaining bits in the short message 401 of the DCI.

For example, use bit 3 in the short message 401 to represent x. In one example, bit 3=0 means x=2, bit 3=1 means x=3; or, use bit 3 and bit 4 to represent x. In an example, “00” in bit 3 and bit 4 means x=0, “01” means x=1, “10” means x=2, and “11” means x=3.

As shown in FIG. 4(b), the first indication information may be carried in bit 1 and/or bit 2 of the short message of the DCI.

For example, bit 1 and bit 2 in short message 401 are reused to represent x. In one example, bit 1 and bit 2 are "00" to indicate x=0, and bit 1 and bit 2 are "01" to indicate x=1. "10" for bit 1 and bit 2 means x=2, and "11" for bit 1 and bit 2 means x=3.

As shown in (c) of FIG. 4, the first indication information may be carried in reserved bits of the DCI.

For example, the reserved bits 402 in the DCI are used to represent x. In one example, one or more reserved bits can be used to represent x. The usage is the same as in (a), for example: 1 reserved bit is used to represent x, in one example, this bit=0 means x=2, this bit=1 means x=3; or, use 2 reserved bits to Represents x. In an example, the two reserved bits are "00", which means x=0, "01" means x=1, "10" means x=2, and "11" means x=3.

In this embodiment, as shown in FIG. 3, the method further includes:

Step 303: The network device sends second indication information, where the second indication information is used to instruct the terminal device to apply the updated SI.

By sending the second instruction information, the terminal device can apply the updated SI under the instruction of the second instruction information. For example, the terminal device may apply the updated SI in the modification period in which the second indication information is received. In addition, the second indication information may further indicate in which modification period the terminal device applies the updated SI.

In one embodiment, in step 303, the network device may send the second indication information in a modification period starting from the foregoing earliest modification period. The network device may determine whether the sending situation of the SI update instruction satisfies the first condition from the earliest modification period mentioned above, and send the second instruction information when the first condition is met. The first condition means that the SI update instruction is delivered to a predetermined number of terminal devices. The predetermined number of terminal devices, for example, refers to all terminal devices served by the network device.

In step 303 of this embodiment, the network device may send the second indication information in the following manner:

The second indication information may be carried in 1 remaining bit in the short message used to transmit the downlink control information (DCI) of the SI update indication. For example, refer to FIG. 4(a); or, the second indication information may One bit of the reserved bits carried in the DCI, for example, can refer to Figure 4(c); or, the second indication information can be carried in the use of system information-radio network temporary identification (SI-RNTI) plus The reserved bits in format 1_0 of scrambled or addressed DCI.

In this embodiment, as shown in FIG. 3, the method further includes:

Step 304: The network device sends the updated SI in a modification period next to the modification period in which the SI update indication is sent.

For example, if the network device sends the SI update instruction in the modification period M, then the network device can send the updated system information (SI) in the modification period (M+1).

In this embodiment, as shown in FIG. 3, the method further includes:

Step 305: Calculate the first number according to the required number of modification periods and the modification period for sending the SI update indication.

For example, the number of required modification periods is x ₀ , and the initial modification period for sending the SI update instruction is the modification period M. If the modification period of the SI update instruction sent to a certain terminal device is the modification period M, then the first A quantity x=x ₀ , if the modification period of the SI update indication sent to another terminal device is the nth modification period (n is a natural number) after the modification period M, that is, the modification period (M+n), then the A quantity x=x ₀ -n.

In this embodiment, the number of required modification cycles x ₀ described above can be calculated according to the channel load and the paging opportunity. For example, the terminal device can estimate the number of modification cycles x ₀ required to send SI update instructions to a predetermined number of terminal devices according to the current channel load and paging opportunities, where the predetermined number of terminals may be served by the network device, for example. All terminal equipment.

According to the method shown in Figure 3, the network device can send an SI update instruction to a terminal device in the modification period M, and predict the number of modification periods required to notify all terminals according to the current channel load and paging opportunity situation, and according to the current Determine the first number x (for example, if the network device determines that the required number of modification cycles is 2, then when the modification cycle M transmits the SI update instruction to the terminal device, it is determined that x=2; in the modification cycle M+1, When the terminal device transmits the SI update instruction, it determines x=1), the determined first quantity x is sent to the terminal device as the first instruction information; the updated SI is sent in the modification period (M+1), and the modified SI From period (M+x), it is determined whether the SI update instruction has been transmitted to all terminals. In the modification period in which it is determined that the SI update instruction has been transmitted to all terminals, the second instruction information is sent. The terminal transmits the SI update instruction, and then judges again in the next modification period, until it is determined that the SI update instruction has been transmitted to all terminals, and sends the second instruction information in the modification period of the judgment.

FIG. 5 is another schematic diagram of the method for updating system information of this embodiment. As shown in FIG. 5, the method includes:

In this embodiment, as shown in FIG. 5, the method may further include:

Step 503: The network device sends third indication information that the SI has been updated.

In this embodiment, by sending the third instruction information, the terminal device can be instructed that the SI should be updated, and under the instruction of the third instruction information, obtain the updated SI and apply the updated SI. For example, the terminal device may obtain the updated SI in the modification period in which the third indication information is received, and apply the updated SI in the modification period. In addition, the third indication information may further indicate in which modification period the terminal device obtains and applies the updated SI.

In one embodiment, in step 503, the network device may send the third indication information in a modification period from the earliest modification period. The network device may determine whether the sending situation of the SI update instruction satisfies the first condition from the earliest modification period mentioned above, and when the first condition is met, send the third instruction information. This first condition is the same as the first condition in the above description.

In step 503 of this embodiment, the network device may send the third indication information in the same manner as sending the second indication information. For example, the third indication information may be sent in the following manner:

The third indication information may be carried in 1 remaining bit in the short message used to transmit the downlink control information (DCI) of the SI update indication. For example, refer to FIG. 4(a); or, the third indication information may One bit of the reserved bits carried in the DCI, for example, can refer to Figure 4(c); or, the third indication information can be carried in the use of system information-radio network temporary identification (SI-RNTI) plus The reserved bits in format 1_0 of scrambled or addressed DCI.

In this embodiment, as shown in FIG. 5, the method may further include:

Step 504: The network device also sends the updated SI in the modification period of sending the third indication information.

For example, the network device sends the SI update instruction in the modification period (M+x), and the network device may send the updated system information (SI) in the modification period (M+x).

In this embodiment, as shown in FIG. 5, the method further includes:

In this embodiment, for the description of step 301, step 302, and step 305 in FIG. 5, reference may be made to the description of step 301, step 302, and step 305 in FIG. 3.

According to the method shown in Figure 5, the network device can send an SI update instruction to a certain terminal device in the modification period M, and according to the current channel load and paging opportunities, predict the number of modification periods x ₀ required to notify all terminals, and According to the current modification period M, determine the first number x (for example, the network device determines that the required modification period x ₀ is 2, then when the modification period M transmits the SI update instruction to the terminal device, it is determined that x=2; in the modification period When M+1 transmits the SI update instruction to the terminal device, it is determined that x=1), and the determined first quantity x is sent to the terminal device as the first instruction information; starting from the modification period (M+x), it is determined whether it has been The SI update instruction is delivered to all terminals. In the modification period in which it is determined that the SI update instruction has been delivered to all terminals, the updated SI and the third instruction information are sent. If it is determined that the SI update instruction has not been delivered to all terminals, Then, the judgment is performed again in the next modification period until it is determined that the SI update instruction has been transmitted to all terminals, and the updated SI and the third instruction information are sent in the modification period in which the judgment is made.

In this embodiment, according to the method shown in FIG. 3 and FIG. 5, the terminal device is instructed to acquire or apply the earliest modification period of the updated system information (SI) through the first indication information, so that the terminal device can follow the The earliest modification period obtains or applies the updated system information (SI), so as to prevent the terminal device from using the invalid system information.

The method shown in FIG. 3 or FIG. 5 of the embodiment of the present application can more effectively avoid the problem that the terminal device cannot update the system information, and there is no need to add additional paging opportunities, which can save time and frequency resources, thereby providing users with Data transmission provides more resources.

In addition, in the methods shown in FIG. 3 and FIG. 5, there may also be:

Step 306: Generate the first indication information.

For example, in step 306, the first indication information is generated according to the calculated first quantity.

In addition, in the method shown in FIG. 3, step 302, step 303, step 304, step 305, or step 306 can be freely combined with step 301. For example, the method may only have step 301, or there may be

steps

301 and 302, or There are

steps

301 and 303, etc. In the method shown in FIG. 5, step 302, step 305, step 306, or step 503 can be freely combined with step 301. For example, the method can only have step 301, or there may be

steps

FIG. 6 is another schematic diagram of the method for updating system information in this embodiment, and the method includes:

Step 601: In a modification period, the network device sends a paging including the same short message; and/or, in a modification period, the network device provides at least two paging opportunities for at least one terminal.

In this embodiment, step 601 can enable a terminal to have at least 2 paging opportunities in one modification period, thereby increasing the paging opportunities and reducing the possibility that the terminal device cannot update system information.

In this embodiment, in a modification period, the short messages included in the paging sent by the network device are the same. For example, the SI update indication can be sent from the beginning of a modification period in which the SI update indication is sent.

In this embodiment, in one modification period, the network device provides at least two paging opportunities for at least one terminal. In this embodiment, for example, the value of the modification period coefficient (modificationPeriodCoeff) of the NR-based access to unlicensed spectrum (NR-U) sent by the network device is greater than or equal to 2. For example, the value can be greater than 4, or greater than 8, and so on. In addition, in one embodiment, the network device provides the terminal with at least two paging opportunities in one modification period, and it may actually send a page on only one paging opportunity.

In addition, as shown in Figure 6, the method may further include:

Step 602: The network device generates a short message.

In this embodiment, the network device sends the SI update indication by time/frequency multiplexing with the DRS, and/or the network device sends a page including the SI update indication on a public paging opportunity, so that it can be Fewer resources notify the terminal device of the SI change. The SI update indication can be included in the short message, which is the same as the current NR mechanism; it can also use only 1 bit, 0 means that the SI is not updated, 1 means that the SI is updated, or 1 means that the SI is not updated, and 0 means that the SI is updated.

In this embodiment, the paging may be a broadcast paging.

In this embodiment, the public paging opportunity may be an existing paging opportunity of terminal equipment or a newly-added paging opportunity.

In this embodiment, as shown in FIG. 27, the method further includes:

Step 2702, the network device determines whether to send the SI update indication on the at least one public paging opportunity based on listening before dialogue (LBT).

In step 2702, the LBT may be, for example, a second-level pre-conversation monitoring (CAT 2LBT) of 25 microseconds.

When it is determined that the SI update instruction can be sent on the at least one public paging opportunity, step 2701 may be performed, that is, the SI update instruction is sent on the at least one public paging opportunity.

In this embodiment, as shown in FIG. 27, the method further includes:

Step 2703: The network device sends fourth indication information, where the fourth indication information is used to instruct the terminal device to start or end monitoring the public paging opportunity and/or the paging opportunity of the terminal device.

In this embodiment, ending the monitoring of the public paging opportunity and/or the paging opportunity of the terminal device may also be stopping or no longer monitoring the public paging opportunity and/or the paging opportunity of the terminal device.

In this embodiment, when multiple steps are combined, the network device may have a different execution sequence, which is not limited here. For example, step 2701 may be performed first, and then step 2703, or step 2703 may be performed first, and then step 2701 may be performed.

In this embodiment, the fourth indication information may be sent through DRS and/or system information.

In this embodiment, when the terminal device receives the fourth indication information, it can start or end monitoring the public paging opportunity and/or the paging opportunity of the terminal device according to the indication of the fourth indication information.

Example 9

FIG. 28 is a schematic diagram of a method for updating system information in Embodiment 9 of the present application. As shown in Figure 28, the method includes:

Step 2801, the terminal device receives the SI update instruction multiplexed with the DRS; and/or, the terminal device receives a paging including the system information (SI) update instruction on a common paging opportunity.

In this embodiment, the terminal device receives the SI update indication multiplexed with the DRS by monitoring or receiving the DRS, and/or the terminal device receives the paging including the SI update indication on the public paging opportunity, thereby, Fewer resources receive notifications of SI changes.

In this embodiment, the paging may be a broadcast paging.

In this embodiment, as shown in FIG. 28, the method further includes:

Step 2802, the terminal device monitors the DRS, and does not monitor the common paging opportunity and the paging opportunity of the terminal device or does not monitor the paging opportunity of the terminal device.

Therefore, when a network device sends an SI update instruction multiplexed with a Discovery Reference Signal (DRS), the terminal device can listen to the DRS to receive the DRS and the SI update instruction sent together with the DRS, and Do not monitor the common paging opportunity and the paging opportunity of the terminal device or do not monitor the paging opportunity of the terminal device.

In this embodiment, as shown in FIG. 28, the method further includes:

Step 2803: The terminal device monitors the common paging opportunity and/or the paging opportunity of the terminal device.

Therefore, when the network device sends the SI update indication through the public paging opportunity, the terminal device can monitor the public paging opportunity and/or the paging opportunity of the terminal device.

In this embodiment, as shown in FIG. 28, the method further includes:

Step 2804: The terminal device receives fourth indication information, where the fourth indication information is used to instruct the terminal device to monitor or end monitoring the public paging opportunity and/or the paging opportunity of the terminal device.

In this embodiment, as shown in FIG. 28, the method further includes:

Step 2805: The terminal device determines to start and/or stop monitoring the public paging opportunity and/or the paging opportunity of the terminal device based on the timer, and/or the count value, and/or the measurement amount.

In step 2805, the terminal device determines to start and/or stop monitoring the public paging opportunity and/or the paging opportunity of the terminal device based on a timer, including:

When the first timer expires, start monitoring the public paging opportunity and/or stop monitoring the paging opportunity of the terminal device; or, when the first timer expires, start monitoring the public paging opportunity and/or stop Monitor the paging opportunity of the terminal device, and when the second timer expires, stop monitoring the public paging opportunity and/or start monitoring the paging opportunity of the terminal device.

For example, define a timer to determine the monitoring paging opportunity: when a downlink reference signal or downlink transmission is received on the NR-U, the timer is started or restarted; when the timer expires, the terminal device monitors the common paging opportunity And/or the paging opportunity of the terminal device. In addition, when the terminal enters the idle state or inactive state, the timer is started; when the terminal enters the connected state, the timer is released/cleared/stopped. Downlink transmission can be SSB/PBCH, paging, etc.

For another example, define two timers, one for determining monitoring paging and one for stopping monitoring paging: the timer used to determine monitoring paging is the same as the above; for the timer used to stop monitoring paging , When the timer used to determine the monitoring of the paging expires or the terminal equipment monitors the broadcast paging on the public paging opportunity, the timer for stopping monitoring the paging is started; when it is used to stop monitoring the paging When the timer expires, the terminal device stops monitoring the common paging opportunity and/or the paging opportunity of the terminal device; the network can explicitly instruct to restart the timer through downlink transmission, for example, through DCI.

In this embodiment, the foregoing first timer and/or second timer may be defined in advance, and/or configured or activated by the network device. In this embodiment, the above-mentioned parameters and/or thresholds may also be provided by the network device to the terminal device or pre-defined.

In step 2805, the terminal device determining to start and/or stop monitoring the public paging opportunity and/or the paging opportunity of the terminal device based on the count value includes:

When the first count value is greater than or equal to the first threshold, start monitoring the public paging opportunity and/or stop monitoring the paging opportunity of the terminal device; or, when the first count value is greater than or equal to the first threshold, start Monitor the public paging opportunity and/or stop monitoring the paging opportunity of the terminal device, and when the second count value is greater than or equal to a second threshold, stop monitoring the public paging opportunity and/or start monitoring the terminal device Of paging opportunities.

For example, introduce a count value used to determine monitoring paging: when the predetermined downlink reference signal or downlink transmission is not received, the count value is increased by 1; when the count value reaches the maximum value or a predetermined value, the terminal monitors the common paging opportunity And/or the paging opportunity of the terminal device; when a downlink reference signal or downlink transmission is received on the NR-U, the count value is reset. In addition, when the terminal enters the idle state or inactive state, the count value is reset; when the terminal enters the connected state, the counter is released/cleared or the counting-related activities are stopped. Downlink transmission can be SSB/PBCH, paging, etc.

For another example, two count values are introduced, one for determining monitoring paging, and one for stopping monitoring paging. The usage method for determining the count value for monitoring paging is the same as above. For the count value used to stop monitoring paging: when the counter used to determine monitoring paging reaches the maximum value or reaches a predetermined value, initialize the count value used to stop monitoring paging or make the count value 0; in NR- When a downlink reference signal or downlink transmission or broadcast paging is received on U, the count value is increased. ; When the count value reaches the maximum value or. When a predetermined value is reached, the terminal stops monitoring public paging opportunities for broadcast paging.

In this embodiment, the above counting process may be predefined, and/or configured or activated by the network device. In this embodiment, the aforementioned parameters and/or thresholds may also be provided by the network device to the terminal device or predefined.

In step 2805, the terminal device determining to start and/or stop monitoring the public paging opportunity and/or monitoring the paging opportunity of the terminal device based on the measurement amount includes:

When the evaluation result using the first evaluation formula of the measured quantity satisfies the first predetermined condition, start monitoring the public paging opportunity and/or stop monitoring the paging opportunity of the terminal device, when using the first measurement quantity When the evaluation result of an evaluation formula satisfies the second predetermined condition, stop monitoring the public paging opportunity and/or start monitoring the paging opportunity of the terminal device; or, when the evaluation result of the first evaluation formula of the measurement quantity is used When the third predetermined condition is met, start monitoring the public paging opportunity and/or stop monitoring the paging opportunity of the terminal device, and stop when the evaluation result of the second evaluation formula using the measurement quantity meets the fourth predetermined condition Monitor the public paging opportunity and/or start monitoring the paging opportunity of the terminal device.

For example, only one evaluation formula is used to determine the behavior of the terminal using the entry and exit conditions, that is, when the channel load and/or interference is sufficiently high, the terminal monitors the common paging opportunity and/or monitors the paging opportunity of the terminal device ; When the channel load and/or interference is low enough, the terminal stops monitoring the common paging opportunity and/or monitoring the paging opportunity of the terminal device.

For another example, two evaluation formulas are used to determine monitoring paging and stopping monitoring paging respectively.

In this embodiment, the above-mentioned measurement quantity may be load-related, for example, resource usage, and/or channel occupancy rate, etc.; or, the above-mentioned measurement quantity may also be interference-related, for example, the signal to interference plus noise ratio ( Signal to Interference plus Noise Ratio, SINR), and/or received signal strength indication (Received Signal Strength Indication, RSSI), etc.

In this embodiment, the above-mentioned determination mechanism based on the measurement amount may be defined in advance, and/or configured or activated by the network device. In this embodiment, the aforementioned parameters and/or thresholds may also be provided by the network device to the terminal device or predefined.

As shown in Figure 28, the method may further include:

Step 2806: The terminal device determines the modification period for obtaining the updated SI according to the modification period for receiving the SI update instruction.

For example, in step 2806, the terminal device may use the next modification period of the modification period in which the SI update instruction is received as the modification period for obtaining the updated SI.

In this embodiment, as shown in FIG. 28, the method further includes:

Step 2807: Obtain the updated SI.

For example, in step 2807, the updated SI may be obtained in the next modification period of the modification period in which the SI update indication is received. In this embodiment, the terminal device receives the SI update instruction multiplexed with the DRS by monitoring/receiving the DRS, and/or the terminal device receives the SI update instruction on the public paging opportunity, thereby, it can use less resources Receive notification of SI changes.
