Description

Technical Field

[0001] This disclosure relates to the field of wireless communication technology, and in particular to a method, apparatus, and readable storage medium for transmitting synchronization signal power information. Background Technology

[0002] In some wireless communication technologies, low-power (LP) wakeup signals (WUS) can be applied. When using LPWUS, the dedicated receiver corresponding to LPWUS can be called an LPWUS receiver. User equipment (UE) uses the primary transceiver to process uplink and downlink data and uses a dedicated receiver to receive LPWUS. For example, if the UE's primary transceiver is in sleep mode, receiving LPWUS through the dedicated receiver will activate the primary transceiver, putting it into operation. If the UE's primary transceiver is in sleep mode and the dedicated receiver does not receive LPWUS, or if it receives LPWUS but the LPWUS instruction does not wake it up, the primary transceiver will remain in sleep mode.

[0003] LPWUS receivers require a synchronization signal to maintain their local clock. Considering that the LPWUS receiver's sensitivity is lower than the master receiver's (e.g., the master receiver's sensitivity is -110dBm while the LPWUS receiver's is -80dBm), the synchronization signal for the LPWUS receiver needs to be enhanced. Furthermore, in related technologies, LPWUS receivers often cannot accurately determine when to activate, leading to increased power consumption. Summary of the Invention

[0057] like Figure 1 As shown, the method for transmitting synchronization signal power information provided in this disclosure can be applied to a wireless communication system 100, which may include, but is not limited to, a network device 101 and a user equipment 102. The user equipment 102 is configured to support carrier aggregation, and the user equipment 102 can be connected to multiple carrier units of the network device 101, including a primary carrier unit and one or more secondary carrier units.

[0063] This disclosure provides a method for transmitting synchronization signal power information. Figure 2 This is a flowchart illustrating a method for transmitting synchronization signal power information according to an exemplary embodiment, such as... Figure 2 As shown, the method includes steps S201 to S202, specifically:

[0064] Step S201: The first network device sends the power configuration information of the synchronization signal to the user equipment.

[0065] The power configuration information of the synchronization signal sent by the first network device to the user equipment is used to indicate the power information of the synchronization signal corresponding to the set receiver of the user equipment. The set receiver is used to receive the low power wake-up signal. In one example, this set receiver can be called the LPWUS receiver.

[0066] After the user equipment receives the power configuration information of the synchronization signal, it can know the power information of the synchronization signal that the LPWUS receiver needs to receive.

[0067] In some possible implementations, the synchronization signal is a synchronization signal for an LP WUS receiver.

[0068] In some possible implementations, the first network device sends the power configuration information of the synchronization signal to the user equipment by sending dedicated signaling to the user equipment, which includes the power configuration information of the synchronization signal.

[0069] In some possible implementations, the first network device sends the power configuration information of the synchronization signal to the user equipment by broadcasting a system message, which includes the power configuration information of the synchronization signal.

[0070] In some possible implementations, the power information is the power offset of the synchronization signal relative to the power of the synchronization signal block SSB (SS / PBCH block).

[0071] For example, the power of the synchronization signal is Pa, the power of the SSB is Pb, and the power offset of the synchronization signal relative to the power of the SSB is Pc, where Pc is Pa-Pb.

[0072] In some possible implementations, the power information is the positive difference between the power of the synchronization signal and the power of the synchronization signal block SSB (SS / PBCH block).

[0073] For example, the power of the synchronization signal is P1, the power of the SSB is P2, the positive difference between the power of the synchronization signal and the power of the SSB is P3, the value of P3 is positive, and the value of P3 is P1-P2.

[0074] By ensuring that the power of the synchronization signal indicated by the power configuration information is greater than the power of the SSB, the problem of the small coverage area of ​​the LPWUS receiver caused by the lower sensitivity of the LPWUS receiver compared to the main receiver can be overcome. This effectively increases the coverage area of ​​the synchronization signal used for the LPWUS receiver and improves the coverage performance of the synchronization signal.

[0075] Step S202: The first network device sends the time-frequency configuration information of the synchronization signal to the user equipment.

[0076] The time-frequency configuration information includes at least one of the following: frequency domain position, time domain period, and time domain position offset.

[0077] In one example, a first network device broadcasts a system message that includes the power configuration information of the synchronization signal and the time-frequency configuration information of the synchronization signal.

[0078] In one example, the first network device broadcasts two system messages, one of which includes the power configuration information of the synchronization signal, and the other of which includes the time-frequency configuration information of the synchronization signal.

[0079] Step S203: The first network device sends the time-frequency configuration information of the synchronization signal to the second network device.

[0080] The time-frequency configuration information of the synchronization signal includes at least one of the following: frequency domain position, time domain period, and time domain position offset.

[0081] In some possible implementations, the cell managed by the second network device is a neighboring cell of the cell managed by the first network device.

[0082] In this embodiment of the disclosure, the first network device sends the power configuration information of the synchronization signal corresponding to the LPWUS receiver of the user equipment to the user equipment. This allows the user equipment to know the power configuration of the synchronization signal corresponding to the LPWUS receiver, and thus enables the user equipment to determine when to turn on the LPWUS receiver when the main receiver is in operation based on this power configuration information and the known sensitivity of the LPWUS receiver. This allows the user equipment to more accurately control the turning on and off of the main receiver and the LPWUS receiver, thereby saving the power consumption of the user equipment.

[0083] Furthermore, by sending the time-frequency configuration information of the synchronization signal to the second network device, the first network device can avoid inter-cell interference. Specifically, after the first network device enhances the power of the synchronization signal corresponding to the LPWUS receiver of the user equipment in the cell it manages, it may cause interference to other neighboring cells. Therefore, it is necessary to notify the network devices of other cells, namely the second network device, of the time-frequency configuration information of this synchronization signal, so that the second network device can avoid the time-frequency position of this synchronization signal when scheduling, thereby avoiding inter-cell interference.

[0084] This disclosure provides a method for transmitting synchronization signal power information. Figure 3 This is a flowchart illustrating a method for transmitting synchronization signal power information according to an exemplary embodiment, such as... Figure 3 As shown, the method includes steps S301 to S302, specifically:

[0085] Step S301: The first network device broadcasts a system message, which includes power configuration information and time-frequency configuration information of the synchronization signal.

[0086] The power configuration information is used to indicate the power information of the synchronization signal corresponding to the set receiver of the user equipment. The set receiver is used to receive the low-power wake-up signal. In one example, this set receiver can be called the LPWUS receiver.

[0087] The time-frequency configuration information of the synchronization signal includes at least one of the following: frequency domain position, time domain period, and time domain position offset.

[0088] Step S302: The first network device sends the time-frequency configuration information of the synchronization signal to the second network device.

[0089] In some possible implementations, the cell managed by the second network device is a neighboring cell of the cell managed by the first network device.

[0090] This disclosure provides a method for transmitting synchronization signal power information. Figure 4 This is a flowchart illustrating a method for transmitting synchronization signal power information according to an exemplary embodiment, such as... Figure 4 As shown, the method includes steps S401 to S402, specifically:

[0091] In step S401, the first network device broadcasts a first system message, which includes power configuration information for the synchronization signal.

[0092] The power configuration information is used to indicate the power information of the synchronization signal corresponding to the set receiver of the user equipment. The set receiver is used to receive the low-power wake-up signal. In one example, this set receiver can be called the LPWUS receiver.

[0093] In step S402, the first network device broadcasts a second system message, which includes time-frequency configuration information of the synchronization signal.

[0094] The time-frequency configuration information of the synchronization signal includes at least one of the following: frequency domain position, time domain period, and time domain position offset.

[0095] Step S403: The first network device sends the time-frequency configuration information of the synchronization signal to the second network device.

[0096] In some possible implementations, the cell managed by the second network device is a neighboring cell of the cell managed by the first network device.

[0097] It should be noted that the sending order of steps S401, S402, and S403 is not limited to... Figure 4 The order shown can be any order in which steps S401, S402, and S403 are executed.

[0098] This disclosure provides a method for receiving synchronization signal power information, executed by a user equipment. Figure 5 This is a flowchart illustrating a method for receiving synchronization signal power information according to an exemplary embodiment, such as... Figure 5 As shown, the method includes step S501 specifically:

[0099] Step S501: Receive the power configuration information of the synchronization signal sent by the first network device.

[0100] The power configuration information is used to indicate the power information of the synchronization signal corresponding to the set receiver of the user equipment; the set receiver is used to receive the low power wake-up signal, and in one example, the set receiver can be called the LPWUS receiver.

[0101] In some possible implementations, receiving power configuration information of a synchronization signal sent by a first network device includes: receiving dedicated signaling sent by the first network device, the dedicated signaling including the power configuration information of the synchronization signal.

[0102] In some possible implementations, receiving power configuration information of a synchronization signal sent by a first network device includes: receiving a system message broadcast by the first network device, the system message including the power configuration information of the synchronization signal.

[0103] In some possible implementations, the power information of the synchronization signal corresponding to the set receiver of the user equipment is the power offset of the synchronization signal relative to the power of the synchronization signal block SSB.

[0104] For example, the power of the synchronization signal is Pa, the power of the SSB is Pb, and the power offset of the synchronization signal relative to the power of the SSB is Pc, where Pc is Pa-Pb.

[0105] In a specific example, the LPWUS receiver of the user equipment (UE) has a sensitivity of -80 dBm. When the UE is in RRC idle state, it activates its master receiver and receives the SSB through the master receiver. The master receiver measures the Reference Signal Receiving Power (RSRP) of the received SSB. The UE receives a system message broadcast by the first network device, indicating that the LPWUS power is 10 dB higher than the SSB power.

[0106] If the SSB power measured by the master receiver is -100dBm, the user equipment can determine from the system message that the received power of the synchronization signal received by the LPWUS receiver is -90dBm, which does not reach the minimum received power of the LPWUS receiver of -80dBm. Therefore, the user equipment determines that it does not need to turn on the LPWUS receiver.

[0107] If the SSB power measured by the master receiver is -85dBm, the user equipment can determine from the system message that the received power of the synchronization signal received by the LPWUS receiver is -75dBm, which has reached the minimum received power of the LPWUS receiver of -80dBm. Thus, the user equipment determines that the LPWUS receiver needs to be turned on.

[0108] In some possible implementations, the power information of the synchronization signal corresponding to the set receiver of the user equipment is the positive difference between the power of the synchronization signal and the power of the synchronization signal block SSB (SS / PBCH block).

[0109] For example, the power of the synchronization signal is P1, the power of the SSB is P2, the positive difference between the power of the synchronization signal and the power of the SSB is P3, the value of P3 is positive, and the value of P3 is P1-P2.

[0110] In a specific example, the LPWUS receiver of the user equipment (UE) has a sensitivity of -80 dBm. When the UE is in RRC idle state, it activates its master receiver and receives the SSB through the master receiver. The master receiver measures the Reference Signal Receiving Power (RSRP) of the received SSB. The UE receives a system message broadcast by the first network device, indicating that the power offset of the LPWUS compared to the SSB power is -20 dB (i.e., the LPWUS power is -20 dB lower than the SSB power).

[0111] If the SSB power measured by the master receiver is -70dBm, the user equipment can determine from the system message that the received power of the synchronization signal received by the LPWUS receiver is -90dBm, which does not reach the minimum received power of the LPWUS receiver of -80dBm. Therefore, the user equipment determines that it does not need to turn on the LPWUS receiver.

[0112] If the SSB power measured by the master receiver is -60dBm, the user equipment can determine from the system message that the received power of the synchronization signal received by the LPWUS receiver is -80dBm, which has reached the minimum received power of the LPWUS receiver of -80dBm. Thus, the user equipment determines that the LPWUS receiver needs to be turned on.

[0113] By ensuring that the power of the synchronization signal indicated by the power configuration information is greater than the power of the SSB, the problem of the small coverage area of ​​the LPWUS receiver caused by the lower sensitivity of the LPWUS receiver compared to the main receiver can be overcome. This effectively increases the coverage area of ​​the synchronization signal used for the LPWUS receiver and improves the coverage performance of the synchronization signal.

[0114] In some possible implementations, the time-frequency configuration information of the synchronization signal is a default value and does not require configuration by the first network device.

[0115] This disclosure provides a method for receiving synchronization signal power information, executed by a user equipment. Figure 6This is a flowchart illustrating a method for receiving synchronization signal power information according to an exemplary embodiment, such as... Figure 6 As shown, the method includes step S601 in detail:

[0116] Step S601: Receive the power configuration information and time-frequency configuration information of the synchronization signal sent by the first network device.

[0117] In some possible implementations, receiving power configuration information and time-frequency configuration information of a synchronization signal sent by a first network device includes: receiving a system message broadcast by the first network device, wherein the system message includes power configuration information and time-frequency configuration information of the synchronization signal.

[0118] In some possible implementations, receiving the power configuration information and time-frequency configuration information of the synchronization signal sent by the first network device includes: receiving a first system message broadcast by the first network device, the first system message including the power configuration information of the synchronization signal; and receiving a second system message broadcast by the first network device, the second system message including the time-frequency configuration information of the synchronization signal.

[0119] In some possible implementations, receiving the power configuration information and time-frequency configuration information of the synchronization signal sent by the first network device includes: receiving a second system message broadcast by the first network device, the second system message including the time-frequency configuration information of the synchronization signal; and receiving a first system message broadcast by the first network device, the first system message including the power configuration information of the synchronization signal.

[0120] In this embodiment of the disclosure, after the user equipment obtains the power configuration information and time-frequency configuration information of the synchronization signal corresponding to the LPWUS receiver, it determines when to turn on the LPWUS receiver when the main receiver is in working state based on this power configuration information and the known sensitivity of the LPWUS receiver. This enables the user equipment to more accurately control the turning on and off of the main receiver and the LPWUS receiver, saving the power consumption of the user equipment. Furthermore, it can accurately receive the synchronization signal based on the time-frequency configuration information of the synchronization signal.

[0121] This disclosure provides a method for transmitting synchronization signal power information, executed by a first network device. Figure 7 This is a flowchart illustrating a method for transmitting synchronization signal power information according to an exemplary embodiment, such as... Figure 7 As shown, the method includes step S701 in detail:

[0122] Step S701: Send the power configuration information of the synchronization signal to the user equipment.

[0123] The power configuration information is used to indicate the power information of the synchronization signal corresponding to the set receiver of the user equipment; the set receiver is used to receive the low power wake-up signal, and in one example the set receiver can be called an LPWUS receiver.

[0124] In some possible implementations, sending power configuration information of a synchronization signal to a user equipment includes sending dedicated signaling to the user equipment, the dedicated signaling including the power configuration information of the synchronization signal.

[0125] In some possible implementations, sending power configuration information of a synchronization signal to a user equipment includes broadcasting a system message, the system message including the power configuration information of the synchronization signal.

[0126] In some possible implementations, the power information of the synchronization signal corresponding to the set receiver of the user equipment is the power offset of the synchronization signal relative to the power of the synchronization signal block SSB.

[0127] For example, the power of the synchronization signal is Pa, the power of the SSB is Pb, and the power offset of the synchronization signal relative to the power of the SSB is Pc, where Pc is Pa-Pb.

[0128] In a specific example, the LPWUS receiver of the user equipment (UE) has a sensitivity of -80 dBm. When the UE is in RRC idle state, it activates its master receiver and receives the SSB through the master receiver. The master receiver measures the Reference Signal Receiving Power (RSRP) of the received SSB. The UE receives a system message broadcast by the first network device, indicating that the LPWUS power is 10 dB higher than the SSB power.

[0129] If the SSB power measured by the master receiver is -100dBm, the user equipment can determine from the system message that the received power of the synchronization signal received by the LPWUS receiver is -90dBm, which does not reach the minimum received power of the LPWUS receiver of -80dBm. Therefore, the user equipment determines that it does not need to turn on the LPWUS receiver.

[0130] If the SSB power measured by the master receiver is -85dBm, the user equipment can determine from the system message that the received power of the synchronization signal received by the LPWUS receiver is -75dBm, which has reached the minimum received power of the LPWUS receiver of -80dBm. Thus, the user equipment determines that the LPWUS receiver needs to be turned on.

[0131] In some possible implementations, the power information of the synchronization signal corresponding to the set receiver of the user equipment is the positive difference between the power of the synchronization signal and the power of the synchronization signal block SSB (SS / PBCH block).

[0132] For example, the power of the synchronization signal is P1, the power of the SSB is P2, the positive difference between the power of the synchronization signal and the power of the SSB is P3, the value of P3 is positive, and the value of P3 is P1-P2.

[0133] The power configuration information of the first network device indicates that the power of the synchronization signal is greater than that of the SSB. This can overcome the problem of the small coverage range of the LPWUS receiver caused by the lower sensitivity of the LPWUS receiver compared to the main receiver, effectively increasing the coverage range of the synchronization signal used for the LPWUS receiver and improving the coverage performance of the synchronization signal.

[0134] This disclosure provides a method for transmitting synchronization signal power information, executed by a first network device. Figure 8 This is a flowchart illustrating a method for transmitting synchronization signal power information according to an exemplary embodiment, such as... Figure 8 As shown, the method includes step S801 specifically:

[0135] Step S801: Send the power configuration information and time-frequency configuration information of the synchronization signal to the user equipment.

[0136] In some possible implementations, sending power configuration information and time-frequency configuration information of the synchronization signal to the user equipment includes broadcasting a system message, wherein the system message includes both the power configuration information and the time-frequency configuration information of the synchronization signal. That is, the same system message contains both the power configuration information and the time-frequency configuration information of the synchronization signal.

[0137] In some possible implementations, sending power configuration information and time-frequency configuration information of a synchronization signal to a user equipment includes: broadcasting a first system message, the first system message including the power configuration information of the synchronization signal; and broadcasting a second system message, the second system message including the power configuration information of the synchronization signal.

[0138] In some possible implementations, sending power configuration information and time-frequency configuration information of a synchronization signal to a user equipment includes: broadcasting a second system message, the second system message including the power configuration information of the synchronization signal; and broadcasting a first system message, the first system message including the power configuration information of the synchronization signal.

[0139] This disclosure provides a method for transmitting synchronization signal power information, executed by a first network device. Figure 9This is a flowchart illustrating a method for transmitting synchronization signal power information according to an exemplary embodiment, such as... Figure 9 As shown, the method includes step S901 in detail:

[0140] Step S901: Send the power configuration information and time-frequency configuration information of the synchronization signal to the user equipment.

[0141] Step S902: Send the time and frequency configuration information to the second network device.

[0142] In some possible implementations, the cell managed by the second network device is a neighboring cell of the cell managed by the first network device.

[0143] In this embodiment, the first network device sends the time-frequency configuration information of the synchronization signal to the second network device to avoid inter-cell interference. Specifically, after the first network device enhances the power of the synchronization signal corresponding to the LPWUS receiver of the user equipment in the cell it manages, it may cause interference to other neighboring cells. Therefore, it is necessary to notify the network devices of other cells, namely the second network device, of the time-frequency configuration information of this synchronization signal, so that the second network device can avoid the time-frequency position of this synchronization signal when scheduling, thereby avoiding inter-cell interference.
