[0136] As shown in FIG. 1 , a communication system 100 includes a terminal 101 and a network device 102 .

[0137] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

[0140] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0141] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0142] In some embodiments, the core network device can be a device including one or more network elements, or it can be multiple devices or device groups, each including all or part of one or more network elements. The network element can be virtual or physical. The core network includes, for example, at least one of the Evolved Packet Core (EPC), the 5G Core Network (5GCN), and the Next Generation Core (NGC). Alternatively, the core network device refers to a network element with a specific function, such as the Access Management Function (AMF), the Service Management Function (SMF), etc.

[0143] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0144] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG. 1 , or a part of the main body thereof, but are not limited thereto.

[0145] The entities shown in Figure 1 are examples. The communication system may include all or part of the entities in Figure 1, and may also include other entities outside of Figure 1. The number and form of the entities are arbitrary. The connection relationship between the entities is an example. The entities may be connected or disconnected, and the connection may be in any manner, which may be direct or indirect, and may be wired or wireless.

[0146] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication processing methods, and next-generation systems based on and extending these. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0147] In the embodiment of the present disclosure, the sensitivity of LR is lower than that of MR. For example, the RSRP sensitivity of MR is -110dB, while the receiving sensitivity of LR is -80dB. Under the same power conditions, the coverage performance of LR receiving low-power signals is poorer than that of MR receiving signals. In order to enhance coverage, there may be a situation where power boosting is performed on low-power signals. For example, compared with signals transmitted through conventional NR channels (legacy NR channels), such as reference signals, the transmit power of low-power signals can be enhanced. Among them, the network device 102 needs to configure the power offset value of the low-power signal relative to the signal transmitted through the conventional NR channel.

[0148] For the same serving cell, the frequency domain location of the low-power signal may differ from the frequency domain location of the signal transmitted over the regular NR channel, and the reception conditions of the LR and MR may differ. A method for determining the timing of activating the LR in this scenario is required.

[0149] FIG2 is an interactive diagram illustrating a method for activating a low-power receiver according to an embodiment of the present disclosure. As shown in FIG2 , an embodiment of the present disclosure relates to a method for activating a low-power receiver, the method comprising:

[0150] In step S2101 , the network device 102 sends instruction information to the terminal 101 .

[0151] In some embodiments, the indication information is used to indicate an offset, wherein the offset is used by the terminal 101 to determine whether to activate the LR.

[0152] In some embodiments, the offset includes a first offset caused by the different frequency domain positions of the reference signal and the low-power signal. The first offset is used to indicate the offset between the MR measurement result and the inferred measurement result obtained by LR measurement due to the different frequency domain positions of the reference signal and the low-power signal. For example, the first offset is the offset between the first measurement result and the second measurement result, wherein the first measurement result is the measurement result of MR based on the reference signal, and the second measurement result is the measurement result of LR measurement inferred (or inferred) based on the first measurement result of MR, that is, the second measurement result is not obtained by LR actually measuring the low-power signal.

[0153] In some examples, the first offset may be denoted as RSRP_offset btwf1 / f2 or RSRQ_offset btwf1 / f2 .

[0154] In some examples, the offset includes at least one of the following: a first offset, a receiving power offset between multiple low-power signals with different time domain lengths, and a transmitting power offset between a reference signal and the low-power signal. Please refer to the description of the following embodiments.

[0155] In some embodiments, the indication information is sent via system information SI. For example, the network device 102 broadcasts the indication information via SI to indicate the offset of the terminal 101 in the idle state or the connected state.

[0156] In some embodiments, step S2101 may be omitted. For example, the above-mentioned offset may be defined through a protocol, in which case step S2101 may be omitted.

[0157] In some embodiments, the terminal 101 receives indication information to obtain the above-mentioned offset.

[0158] Step S2102 : The network device 102 sends a reference signal to the terminal 101 .

[0159] In some embodiments, the reference signal may be a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS), and the reference signal may be transmitted through the aforementioned legacy NR channels.

[0160] In some embodiments, the reference signal and the low power consumption signal are at different frequency domain locations. For example, the reference signal and the low power consumption signal are on different carriers or frequency bands.

[0161] In some embodiments, the low-power signal may be an LP WUS or a low-power synchronization signal (LP SS). Compared to the reference signal, the network device 102 may perform power boosting when transmitting the low-power signal. Therefore, there may be a transmit power offset between the reference signal and the low-power signal. This transmit power offset may be recorded as a power offset.

[0162] In some embodiments, terminal 101 receives a reference signal via MR.

[0163] In step S2103 , the terminal 101 obtains a measurement result by measuring the reference signal through MR.

[0164] In some embodiments, the measurement result is used by the terminal 101 to infer the reception quality of the LR or to infer the measurement result of the LR.

[0165] In some embodiments, the measurement result includes at least one of the following: RSRP, RSRQ, or Signal to Interference plus Noise Ratio (SINR).

[0166] In step S2104 , the terminal 101 determines the first value and / or the second value according to the measurement result and the offset.

[0167] In some embodiments, the measurement result may be RSRP and / or RSRQ.

[0168] In some embodiments, the first value is used to represent the measurement result of the LR corresponding to the RSRP inferred by the terminal 101. The second value is used to represent the measurement result of the LR corresponding to the RSRQ inferred by the terminal 101.

[0169] In some embodiments, the offset may include the first offset RSRP_offset described above btwf1 / f2 or RSRQ_offset btwf1 / f2 .

[0170] In some embodiments, the offset also includes: a received power offset between multiple low-power signals with different time domain lengths. length , and / or, the transmit power offset between the reference signal and the low power signal. For example, the LP SS may have different time domain lengths and there is an offset length .

[0171] In some examples, the offset includes: a first offset, a receive power offset, and a transmit power offset.

[0172] Different low-power signals may have the same or different time domain lengths. For example, taking LP SS as an example, the LP SS may include an LP SS of a first length and an LP SS of a second length, where the first length is different from the second length and there is a received power offset between the two.

[0173] In one example, the receive power offset may be indicated by the aforementioned indication information, or the network device 102 may indicate it through other information, or may be defined through a protocol.

[0174] In another example, the transmit power offset may be indicated by the aforementioned indication information, or indicated by the network device 102 through other information, or defined by a protocol. For example, the transmit power offset may be 0 or not configured.

[0175] In some embodiments, the first value is a value determined according to RSRP and an offset, and the second value is a value determined according to RSRQ and an offset.

[0176] In some embodiments, when the measurement results are different (i.e., RSRP or RSRQ), the configured or defined offsets are different, such as the first offsets. Thus, the terminal 101 determines the first value or the second value in different ways. The following examples describe how to determine the activation of the LR based on the first value or the second value.

[0177] In the first example, the offset is an offset corresponding to RSRP, for example, the offset includes a first offset RSRP_offset corresponding to RSRP btwf1 / f2 Among them, the first value R LR Determined as follows:

[0178] in, It represents the first measurement result, which is RSRP in this embodiment.

[0179] Among them, the first offset RSRP_offset btwf1 / f2 The offset is the offset between the RSRP received by the MR and the RSRP inferred by the LR due to the LR and MR being in different frequency domain locations.

[0180] The power offset represents the transmit power offset of the low-power signal compared to the reference signal. The offset can be configured by the base station or be 0.

[0181] Among them, offset length Indicates the received power offset related to the time domain length of a low power signal such as an LP SS.

[0182] In the second example, the offset is an offset corresponding to RSRP, for example, the offset includes a first offset RSRP_offset corresponding to RSRP btwf1 / f2 .in:

[0183] The first value R LR Determined as follows:

[0184] In this example, the offset is the offset corresponding to RSRP, and the second value is determined based on the first value, RSRP, RSRQ, and the offset.

[0185] Second value Determined as follows:

[0186] in, represents RSRP, represents RSRQ, k1 represents the coefficient of noise or interference, and the meaning of the parameters can also be found in the description of the above embodiment.

[0187] k1 is used to estimate the noise or interference when the LR receives the low-power signal from the noise or interference when the MR receives the SSB.

[0188] In some examples, k1=B LPWUS / B SSB , where B SSB is the frequency domain bandwidth of SSB, B LPWUS is the frequency domain bandwidth of the LP WUS, or, k1 = B LPSS / B SSB , where B SSB is the frequency domain bandwidth of SSB, B LPSS is the frequency domain bandwidth of LP WUS.

[0189] In the third example, the offset is an offset corresponding to RSRQ, for example, the offset includes a first offset RSRP_offset corresponding to RSRQ btwf1 / f2 .

[0190] In this example, the offset is an offset corresponding to RSRQ, and the second value is determined according to RSRP, RSRQ, and the offset.

[0191] Among them, the second value Determined as follows:

[0192] in, represents RSRP, Represents RSRQ. For the meaning of the parameter, please refer to the description of the above embodiment.

[0193] In the fourth example, the offset is an offset corresponding to RSRQ, for example, the offset includes a first offset RSRQ_offset corresponding to RSRQ. btwf1 / f2 .

[0194] In this example, the offset is an offset corresponding to the RSRQ, and the second value is determined based on the RSRQ and the offset.

[0195] Among them, the second value Determined as follows:

[0196] in, Indicates RSRQ, RSRQ_offset btwf1 / f2 Indicates the first offset corresponding to RSRQ.

[0197] In this example, the power offset power offset and the receive power offset offsetlength is 0.

[0198] In the fifth example, the offset includes a first offset RSRP_offset corresponding to RSRP btwf1 / f2 The second offset RSRQ_offset corresponding to RSRQ btwf1 / f2 , the first value is determined based on the RSRP and the offset corresponding to the RSRP;

[0199] The second value is determined based on the first value, RSRP, RSRQ, and an offset corresponding to RSRQ, or the second value is determined based on RSRP, RSRQ, and an offset corresponding to RSRQ.

[0200] The first value R LR Determined as follows:

[0201] Second value Determined as follows: or,

[0202] In this example, the method for determining the first value may refer to the first example or the second example, and the method for determining the second value may refer to the third example or the fourth example.

[0203] It is worth noting that the offset corresponding to RSRP may include: a first offset corresponding to RSRP, a receive power offset corresponding to RSRP, and a transmit power offset corresponding to RSRP. The offset corresponding to RSRQ may include: a first offset corresponding to RSRQ, a receive power offset corresponding to RSRQ, and a transmit power offset corresponding to RSRQ. The receive power offset corresponding to RSRP may be the same as the receive power offset corresponding to RSRQ, and / or the transmit power offset corresponding to RSRP may be the same as the transmit power offset corresponding to RSRQ.

[0204] Step S2105: Terminal 101 determines whether to activate LR according to the first value and / or the second value.

[0205] In some embodiments, activating the LR may also be referred to as activating the LR working mode. When the LR is activated or the LR working mode is activated, the terminal 101 performs monitoring and / or RRM measurements through the LR, while the MR may be in a sleep state to achieve energy saving.

[0206] In some embodiments, the first value and the second value each have a corresponding threshold value. For example, a first threshold value corresponding to the first value is configured by the network device 102 or defined by a protocol, where the first threshold value is a threshold value corresponding to RSRP; a second threshold value corresponding to the second value is configured by the network device 102 or defined by a protocol, where the second threshold value is a threshold value corresponding to RSRQ. For example, the first threshold value is recorded as (Threshold0+delta0), and the second threshold value is recorded as (Threshold-q0+delta-q0).

[0207] Among them, delta0 can be a value configured by the network device 102 or defined by the protocol, which is used to ensure a certain degree of received signal power margin to avoid the situation where the low-power signal cannot be detected when the low-power signal reception level fluctuates after LR is activated. Delta0 can be configured or not configured. Threshold0 can be the minimum received power (or receiver sensitivity) required for LR to correctly detect the low-power signal. Threshold0 can be a value determined by the terminal itself, or a value configured by the network device 102 or defined by the protocol.

[0208] Delta-q0 can be a value configured by the network device 102 or defined by the protocol to ensure a certain degree of received signal quality margin to avoid the situation where the low-power signal cannot be detected when the low-power signal reception level fluctuates after LR is turned on. Delta-q0 can be configured or not configured. Threshold-q0 can be the minimum RSRQ (or receiver sensitivity) required for LR to correctly detect the low-power signal. Threshold-q0 can be a value determined by the terminal 101 itself or a value configured by the network device 102 or defined by the protocol.

[0209] In some embodiments, the LR is activated when the first value is greater than or equal to a first threshold, and / or the second value is greater than or equal to a second threshold.

[0210] In some embodiments, when the measurement results are different (i.e., RSRP or RSRQ), the configured or defined offsets are different, such as the first offsets. Consequently, the terminal 101 determines the first value or the second value in different ways, and the method for determining whether to activate the LR using the first value or the second value also differs. In conjunction with the aforementioned examples, the following further describes the method for determining the activation of the LR based on the first value or the second value in different examples.

[0211] In the first example above, the offset is the offset corresponding to RSRP, for example, the offset includes the first offset RSRP_offset corresponding to RSRP btwf1 / f2 In this example, the terminal 101 determines whether to activate LR based on the first value. If the first value is greater than or equal to the first threshold, that is, RLR >=(Threshold0+delta0), Terminal 101 activates LR. Otherwise, Terminal 101 does not activate LR.

[0212] In the second example above, the offset is the offset corresponding to RSRP, for example, the offset includes the first offset RSRP_offset corresponding to RSRP btwf1 / f2 In this example, the terminal 101 determines whether to activate the LR according to the first value and / or the second value.

[0213] In this example, when the first value is greater than or equal to the first threshold value R LR >=(Threshold0+delta0), and / or the second value is greater than or equal to the second threshold, i.e. When , Terminal 101 activates LR.

[0214] In the third example above, the offset is the offset corresponding to RSRQ, for example, the offset includes the first offset RSRP_offset corresponding to RSRQ btwf1 / f2 In this example, the terminal 101 determines whether to activate the LR according to the second value.

[0215] In this example, when the second value is greater than or equal to the second threshold value, When , Terminal 101 activates LR.

[0216] In the fourth example above, the offset is the offset corresponding to RSRQ, for example, the offset includes the first offset RSRQ_offset corresponding to RSRQ btwf1 / f2 In this example, the terminal 101 determines whether to activate the LR according to the second value.

[0217] In this example, when the second value is greater than or equal to the second threshold value, When , Terminal 101 activates LR.

[0218] In the fifth example above, the offset includes the first offset RSRP_offset corresponding to RSRP btwf1 / f2 The first offset RSRQ_offset corresponding to RSRQ btwf1 / f2 In this example, the terminal 101 determines whether to activate the LR according to the first value and the second value.

[0219] In this example, when the first value is greater than or equal to the first threshold value R LR >=(Threshold0+delta0), and the second value is greater than or equal to the second threshold value, that is, When , Terminal 101 activates LR.

[0220] In some embodiments, activating the LR may also be referred to as turning on the LR or activating the LR to work. If the LR is activated, the terminal 101 will monitor and / or measure via the LR, while the MR will be in a sleep state to achieve energy saving.

[0221] In some embodiments, terminal 101 may include two types of LR. One type of LR, referred to as OOK LR, only supports envelope detection of the OOK symbols of the LP WUS or LP SS. This type of receiver has relatively poor link performance. The other type of LR, referred to as orthogonal frequency division multiplexing (OFDM) LR, can detect the time or frequency domain sequences carried by the OOK symbols of the LP WUS or LP SS, thereby improving link performance.

[0222] In one example, the receiver sensitivity of OOK LR is relatively poor, and the performance of OFDM LR receiver is better than OOK LR, but worse than MR.

[0223] Step S2106: After activating the LR, the terminal 101 monitors the low power consumption signal through the LR.

[0224] In some embodiments, after activating the LR, the terminal 101 may monitor the LP WUS or LP SS through the LR.

[0225] In some embodiments, when it is determined that the LR can be activated based on any of the above examples, it indicates that the signal strength of the low power consumption signal is good enough and the LR can detect the low power consumption signal.

[0226] In an example, if the terminal 101 monitors the LP WUS through the LR, and the LP WUS indicates wake-up, the terminal 101 needs to wake up the MR to communicate with the network device 102 .

[0227] In another example, if terminal 101 monitors the LP SS via the LR, terminal 101 may synchronize based on the LP SS, or perform radio resource management (RRM) measurements based on the LP SS via the LR. The RRM measurements may include RRM measurements of the serving cell and / or RRM measurements of neighboring cells. For example, the LR receives the LP SS of the serving cell to perform RRM measurements of the serving cell, or the LR receives the LP SS of the neighboring cell to perform RRM measurements of the neighboring cell. In this example, RRM measurements by the MR can be avoided or reduced, further reducing terminal power consumption.

[0228] In the disclosed embodiment, the terminal may use the measurement result of the MR and the first offset to determine the timing of activating the LR, thereby improving the accuracy of activating the LR in an inter-frequency scenario, and improving the energy saving effect of the MR while ensuring the LR reception performance.

[0279] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 4 b .

[0280] In an embodiment of the present disclosure, a method can be provided for a UE to determine when to activate the LR to perform LP WUS monitoring and / or RRM measurement when the frequency domain position of the LP WUS or LP SS and the NR legacy channels are in different carriers or different bands. In this embodiment, whether to activate the LR is determined by measuring the NR legacy channels (e.g., SSB) by the MR. The measurement result of the LR is inferred by the measurement result of the MR, and whether to activate the LR is determined based on the inferred measurement result of the LR. Since the MR and the LR will operate on different carriers or bands, there is an offset between the measurement results on different carriers or bands. In this embodiment, the measurement result of the LR is inferred based on the frequency domain offset of the measurement results on different carriers or bands.

[0281] To facilitate understanding of the embodiments of the present disclosure, some examples are listed below:

[0282] Example 1:

[0283] In this example, the RSRP offset is configured and the RSRP is used to determine whether to activate the LR.

[0284] Assume that the RSRP measured by MR for SSB is It can be inferred that the received signal power of LP WUS or LP SS received by LR is

[0285] In some embodiments, it is inferred that the received signal power of the LP WUS or LP SS received by the LR corresponds to the first value of the aforementioned embodiment.

[0286] Among them, RSRP_offset btwf1 / f2 The offset between the estimated RSRP received by the LR and the RSRP received by the MR, caused by the LR and MR being on different carriers / bands. This offset value can be protocol-defined or configured by the base station, for example, through system information.

[0287] The power offset is the power offset of the LP WUS or LP-SS channels compared to the NR legacy channels (e.g., SSB). This offset is configured by the base station. This offset can be 0 or not configured.

[0288] Among them, offset length It is an offset value related to the length of the LP SS.

[0289] In this example, R LR >= (Threshold0 + delta0), the UE determines that LR can be enabled; otherwise, the UE determines that LR should not be enabled. Delta0 can be a value configured by the base station or defined by the protocol to ensure a certain degree of received signal power margin to avoid the situation where the LP WUS or LP SS reception level fluctuates after LR is activated, resulting in the LP WUS or LP SS being unable to be detected. Delta0 can be configured or not configured. Threshold0 can be the minimum received power (or receiver sensitivity) required for LR to correctly detect the LP SS or LP WUS. Threshold0 can be a value determined by the terminal itself or a value configured by the base station or defined by the protocol.

[0290] Example 2:

[0291] In this example, the RSRP offset is configured, and whether to activate the LR is determined based on RSRP and / or RSRQ.

[0292] Assume that the RSRP measured by MR for SSB is RSRQ is It can be inferred that the received signal power of LP WUS or LP SS received by LR is The received signal quality of LP WUS or LP SS received by LR is inferred to be

[0293] In some embodiments, the received signal power of the LP WUS or LP SS received by the LR is inferred to correspond to the first value of the aforementioned embodiment. The received signal quality of the LP WUS or LP SS received by the LR is inferred to correspond to the second value of the aforementioned embodiment.
