Description

Signal measurement, transmission method, device and equipment

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on October 30, 2023, with application number 202311419449.7 and application name “Signal Measurement, Transmission Method, Device and Equipment”, the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0002] The present disclosure relates to the field of communication technology, and in particular to a signal measurement and transmission method, device, and equipment. Background Art

[0003] The terminal energy conservation topic in Release 18 (Rel-18) introduces the concepts of a low-power wake-up signal (LP-WUS) and a low-power wake-up receiver (LP-WUR), further reducing terminal energy consumption based on related energy-saving technologies. When there is no service transmission between the base station and the terminal, the energy-intensive main radio (MR) is turned off, while the LP-WUR is turned on to receive the low-power signal from the base station. When there is service transmission, the base station activates the main radio via the LP-WUS to complete the service transmission. This significantly reduces terminal power consumption when there is no service transmission.

[0004] When the MR enters an extremely low-power state, the LP-WUR is enabled. The LP-WUR periodically measures the channel state to obtain information such as channel status and time-frequency synchronization. However, because the LP-WUR lacks a fast Fourier transform (FFT) module, it cannot receive demodulation reference signals or synchronization signals, and therefore cannot obtain channel status and synchronization information.

Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0368] The following is a brief description of the relevant concepts mentioned in this disclosure.

[0369] 1. Channel State Information Reference Signal (CSI-RS)

[0370] 1.1 CSI-RS Generation

[0371] The Non-Zero Power Channel State Information Reference Signal (NZP-CSI-RS) is generated based on a 31-bit GOLD sequence, initialized by scrambling a 10-bit scrambling identifier (ID) configured by higher layers. It is mapped to the resource elements (REs) occupied by the port using a downlink power allocation factor and a time-frequency orthogonal convolutional code (OCC).

[0372] The Channel State Information Interference Measurement (CSI-IM) signal is a UE-specific configuration in which the base station configures the transmit power of the REs where the CSI-IM resources are located to 0. Only terminals in the radio resource control connected mode (RRC_CONNECTED mode) receive this signal.

[0373] 1.2 CSI-RS Resource Configuration and Function

[0374] Radio Resource Control Connected Mode (RRC_CONNECTED mode): Multiple UE-Specific CSI-RS resource sets configured based on the Channel State Information Measurement Configuration (CSI-MeasConfig) in the Radio Resource Control (RRC) parameter ServingCellConfig. The CSI-RS resource sets include multi-port NZP-CSI-RS for obtaining channel state information, a 1-port or 2-port NZP-CSI-RS resource set for beam management (measuring Layer 1 reference signal received power (L1-RSRP) and Layer 1 reference signal received quality (L1-RSRQ)), and a single-port CSI-IM resource for interference measurement.

[0375] Radio Resource Control Idle / Inactive Mode (RRC_IDLE / INACTIVE mode): One or two Tracking Reference Signal (TRS) resources are configured via System Information Block 1 (SIB1) for precise time-frequency synchronization. Available TRS resources are indicated by the Paging Physical Downlink Control Channel (PDCCH) or Paging Early Indication (PEI).

[0376] 2. Synchronization Signal / PBCH Block (SSB) signal design

[0377] The SSB signal consists of the Primary Synchronization Signal (PSS), the Secondary Synchronization Signal (SSS), and the Physical Broadcast Channel (PBCH). The terminal can obtain time-frequency synchronization information and the cell ID based on the PSS and SSS in the SSB. The PSS and SSS each occupy an Orthogonal Frequency Division Multiplex (OFDM) symbol in the time domain and 12 consecutive Physical Resource Blocks (PRBs) in the frequency domain. In the RRC_IDLE / INACTIVE state, the terminal measures the SSB signal to obtain L1-RSRP and L1-RSRQ.

[0378] 3. Low-power signal generation

[0379] The following are four LP-WUS signal generation methods based on on-off keying (OOK) signal modulation:

[0380] Option OOK-1: One OFDM symbol corresponds to a single bit. The subcarrier (SC) of LP-WUS is:

[0381] OOK=1 means all SCs are used for modulation;

[0382] OOK=0 means that all SCs are at zero power (from the baseband perspective).

[0383] Option OOK-2: Indicates parallel M-bit OOK in the frequency domain. The N SCs of LP-WUS are further divided into M segments, with possible guard bands in between and / or around them. The SCs of LP-WUS are:

[0384] OOK=1 means all SCs in the segment have been modulated;

[0385] OOK=0 means that all SCs in the segment are zero power (from the baseband point of view).

[0386] Option OOK-3: Indicates multi-tone single-bit OOK. The N SCs of LP-WUS are divided into L segments. There is no guard band between segments, but there may be guard bands around the segments. The SCs of LP-WUS are:

[0387] OOK=1 means that one subcarrier of each segment (known to the UE) is modulated and the rest of the SC is zero power (from the baseband perspective);

[0388] OOK=0 means that all SCs in all segments are zero power (from the baseband point of view).

[0389] Option OOK-4: Indicates time-domain M-bit OOK. The N SCs of OOK-4 are generated through a transform (Discrete Fourier Transform (DFT) / least squares).

[0390] The relevant technologies mainly have the following problems:

[0391] 1. LP-WUR does not have an FFT module, does not support OFDM signal demodulation, and cannot distinguish RE-level information. Therefore, the LP-WUS signal cannot use the new radio (NR) CSI-ZP-RS signal to measure the interference power of the current channel. In addition, CSI-ZP-RS is a UE-Specific reference signal in the connected state. When LP-WUR is in the idle (IDLE) state, a cell-specific (Cell-specific) or UE (group)-Specific reference signal is required to measure the channel state. Therefore, it is necessary to design a cell-specific or UE (group)-Specific extremely low power zero power reference signal (Low Power Zero Power Reference signal, LP-ZP-RS) for different LP-WUS signal generation methods (that is, the OOK signal generation method) for LP-WUR to measure interference information.

[0392] 2. When the transmission resource location of the low-power signal conflicts with the transmission resource location of the NR signal, how to design the signal transmission and reception method to avoid the conflict between the reception of the NR signal and the reception of the LP-WUR signal?

[0393] The following describes embodiments of the present disclosure in conjunction with the accompanying drawings. The signal measurement and transmission methods, devices, and apparatuses provided in the embodiments of the present disclosure can be applied to wireless communication systems. The wireless communication system can be a system that uses fifth-generation (5G) mobile communication technology (hereinafter referred to as a 5G system). Those skilled in the art will appreciate that the 5G NR system is only an example and not a limitation.

[0394] Referring to FIG1 , FIG1 is a structural diagram of a network system applicable to an embodiment of the present disclosure. As shown in FIG1 , the network system includes a user terminal 11 and a base station 12. The user terminal 11 may be a user equipment (UE), such as a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a mobile internet device (MID), or a wearable device. It should be noted that the specific type of the user terminal 11 is not limited in the embodiment of the present disclosure. The base station 12 may be a base station of 5G or later versions (e.g., gNB, 5G NR NB), or a base station in other communication systems, or referred to as a node B. It should be noted that in the embodiment of the present disclosure, only a 5G base station is used as an example, but the specific type of the base station 12 is not limited.

[0395] The embodiments of the present disclosure provide an information transmission method, apparatus, terminal, and network equipment to ensure that LP-WUR can also achieve channel state measurement.

[0401] Optionally, the first device mentioned in the embodiment of the present disclosure may be understood as a device that does not include an FFT module. For example, the first device may be an LP-WUR.

[0402] It should be noted that, by sending a first signal with a transmission power of 0 watt to the first device that does not include an FFT module, the first device can also perform channel state measurement and obtain channel state information.

[0403] Optionally, the first signal is an exclusive receiving signal of the first device generated based on a first target signal, and the first target signal includes at least one of the following: an amplitude shift keying (ASK) signal, a frequency shift keying (FSK) signal, and an orthogonal frequency division multiplex (OFDM) signal.

[0404] For example, the first signal may be a very low power reference signal (Low Power Reference signal, LP-RS), LP-WUS, or a very low power synchronization signal (Low Power Synchronization Signa, LP-SS).

[0405] It should be noted that, in order to ensure accurate reception of the first signal, the first device needs to obtain the time-frequency resource position of the first signal before receiving the first signal, and then receive the first signal based on the resource position. Optionally, in one implementation, before receiving the first signal sent by the network device, the method further includes:

[0406] Determining a time-frequency resource position of the first signal according to the first information;

Optionally, the number of repeated transmissions of the first signal may be the maximum number of repeated transmissions of the first signal configured by the network for the first device. For example, if the network side configures the maximum number of repeated transmissions of the first signal to be 5 times, then the first device determines that the actual number of repeated transmissions of the first signal may be less than or equal to 5 times.

[0470] Optionally, in one case, the time-frequency resource position of the first signal can be determined based on the resource position configuration parameters of the second signal. For example, the first device determines the resource position of the second signal through the resource position configuration parameters of the second signal, and the time-frequency resource position of the first signal is associated with the second signal. The association can be agreed upon through a protocol. The first setting can determine the time-frequency resource position of the first signal through the resource position configuration parameters of the second signal sent by the network device and the association between the time-frequency resource position of the first signal and the second signal agreed upon by the protocol; optionally, in another case, the time-frequency resource position of the first signal can be determined based on the second configuration parameters. For example, the first device obtains the resource position of the second signal, and then determines the time-frequency resource position of the first signal through the resource position of the second signal and the second configuration parameters; optionally, in another case, the time-frequency resource position of the first signal can be determined based on the resource position configuration parameters of the second signal and the second configuration parameters. The first device receives the resource position configuration parameters of the second signal sent by the network device to determine the resource position of the second signal, and then determines the time-frequency resource position of the first signal in combination with the second configuration parameters.

[0483] A1222. The first signal occupies at least one OFDM symbol position in at least one time slot in the time domain;

[0484] For example, the OFDM index occupied by the first signal in a slot belongs to one or more of the set {0 to 13}. The time domain length occupied by the first signal can be dynamically determined based on the length of the first signal, or it can be the time domain position occupied by the first signal agreed upon by the protocol (for example, the slot index in the frame occupied by the first signal, the symbol index in the slot).

[0485] A1223. The first signal and the second signal are sent in the same manner, and the sending manner includes: periodic sending or non-periodic sending.

[0486] For example, if the second signal is a periodic signal, the first signal is also a periodic signal; similarly, if the second signal is a non-periodic signal, the first signal is also a non-periodic signal.

[0487] It should be noted that by including the above information in the second configuration parameter, the association relationship between the receiving time-frequency resource positions of the first signal and the second signal can be determined.

[0533] Optionally, whether the indicator parameter satisfies a preset threshold corresponding to the indicator parameter is understood to mean that the indicator parameter is higher or lower than the preset threshold corresponding to the indicator parameter.

[0534] Optionally, in one implementation, the specific implementation of receiving the first signal sent by the network device includes:

[0535] In a case where it is determined that the first signal conflicts with the fifth signal, receiving the first signal sent by the network device based on a first predefined rule;

[0537] The first predefined rule includes at least one of the following:

[0538] D11. Receive the first signal at a position where the first signal and the fifth signal overlap;

[0539] Optionally, in one implementation, when a conflict occurs between the first signal and the fifth signal, the network device transmits only the first signal at the overlapping position and does not transmit the fifth signal, while signals at non-overlapping positions are transmitted normally. Optionally, in another implementation, when a conflict occurs between the first signal and the fifth signal, the network device transmits both the first signal and the fifth signal at the overlapping position, while signals at non-overlapping positions are transmitted normally, and the first device receives only the first signal at the overlapping position and does not receive the fifth signal.

[0540] D12. Receive the fifth signal at a position where the first signal and the fifth signal overlap;

[0541] Optionally, in one implementation, when a conflict occurs between the first signal and the fifth signal, the network device transmits only the fifth signal at the overlapping position and does not transmit the first signal, while signals at non-overlapping positions are transmitted normally.

[0546] It should be noted that the first predefined rule can be understood as the receiving rule of the first device. It should be noted here that the sending of the network device corresponds to the receiving of the first device. How the network device sends is how the terminal receives.

[0547] The following uses the communication between the base station and LP-WUR as an example to illustrate the specific application of the embodiment of the present disclosure.

[0548] Application Scenario 1: Design of LP-ZP-RS (i.e., first signal) for periodic channel state measurement

[0549] Mainly include:

[0550] Step S1: The base station first transmits first configuration parameters of the LP-ZP-RS, or resource location configuration parameters of another signal (i.e., a second signal) associated with the LP-ZP-RS time-frequency resource location, and second configuration parameters to at least one LP-WUR. The base station then transmits the LP-ZP-RS and / or the second signal associated with the LP-ZP-RS location to the at least one LP-WUR.

[0551] Optionally, the LP-ZP-RS is a dedicated reception signal of the LP-WUR generated based on ASK, FSK and / or OFDM signals.

[0552] Optionally, the base station may independently send LP-ZP-RS to LP-WUR periodically or non-periodically, or may simultaneously send a second signal having a fixed time-frequency resource position relationship with LP-ZP-RS to LP-WUR.

[0553] The second signal can be a dedicated receiving signal of LP-WUR generated based on ASK and / or FSK and / or OFDM signals, or it can be an NR reference signal (e.g., CSI-RS) and / or NR synchronization signal (e.g., SSB).

[0554] Optionally, the first configuration parameters of LP-ZP-RS, or the resource location configuration parameters of other signals associated with the LP-ZP-RS position and the second configuration parameters include the time-frequency resource location information of signal reception, the number of transmitting beams, and QCL information, which are used by LP-WUR to determine the receiving time-frequency resource location and other receiving information of LP-ZP-RS.

[0555] Step S2: LP-WUR determines the resource position of LP-ZP-RS based on the first configuration information of LP-ZP-RS, or the resource position configuration parameters of other signals associated with the LP-ZP-RS time-frequency resource position and the second configuration parameters, and receives LP-ZP-RS and / or the second signal associated with the LP-ZP-RS position to obtain channel state information.

[0556] Optionally, the transmission time-frequency resources of the LP-ZP-RS may be determined in any of the following two ways:

[0557] Method 1: LP-ZP-RS is sent independently, and the time-frequency resource position of the first signal is determined based on the first configuration parameter. The specific content of the first configuration parameter can be referred to the above description and will not be repeated here. Specifically, the time-frequency resource sending position of the first signal can be:

[0558] The frequency domain resource position occupies a continuous fixed bandwidth or the frequency domain resource position is non-continuously mapped to a fixed bandwidth (wherein the mapping pattern is fixed, and the unit of the pattern can be a portion of REs in an RB or a portion of RBs in the entire bandwidth of the first device);

[0559] The time domain occupies a fixed OFDM symbol position within at least one slot. For example, the OFDM index occupied within a slot belongs to one or more of the set {0-13}. The time domain length occupied by the first signal can be dynamically determined based on the length of the first signal, or can be determined by the protocol to define the time domain position occupied by the first signal (Slot index within the frame, symbol index within the slot).

[0560] The first signal can be sent periodically or periodically within a specific sending window (the first signal is not sent outside the sending window, and the period of LP-WUR measuring the channel status can be an integer multiple of the sending window period).

[0561] For example, an example application of the first method is: the method of mapping LP-ZP-RS to time-frequency resources can be based on α K,l (n) = 0, n = 1 to N are determined;

[0562] K is the granularity of mapping each bit of LP-ZP-RS to frequency domain resources, which can be K' consecutive subcarriers or RBs or REs; l is the granularity of mapping each bit of LP-ZP-RS to time domain resources, which can be l' consecutive OFDM symbols or slots or ms. The values ​​of K and l can be:

[0563] The value of K is: CRB start is the starting RB position of the first signal, is the total number of RBs or REs occupied by the first signal, N is the signal length of the first signal, and M is the number of bits of the first signal carried by a single OFDM symbol.

[0564] It should be noted that the above parameters may be based on protocol agreement, configured through RRC parameters, or indicated through downlink data / control signals.

[0565] In particular, if the base station side is not configured or the protocol does not agree on the value of M, K is a single subcarrier in the frequency domain. The value range of K is:

[0566] The value range of l is: l start is the starting symbol position of LP-ZP-RS in a slot, N is the signal length of the first signal, and M is the number of bits of the first signal carried by a single OFDM symbol.

[0567] In particular, if the base station side does not configure or the protocol does not agree on M, the first signal occupies one OFDM symbol in the time domain, and i in the above formula = 0. The above parameters can be based on protocol agreement or configured through RRC parameters or indicated by downlink data / control signals.

[0568] Mode 2: The LP-ZP-RS is associated with a periodically transmitted second signal and transmitted. The resource position of the LP-ZP-RS is determined based on a resource position configuration parameter of the second signal and a second configuration parameter indicating an association relationship between the time-frequency resource position of the second signal and the LP-ZP-RS. The association relationship may be that the time domain position of the first signal and the time domain position of the second signal are TDM and / or the frequency domain resource position of the first signal and the frequency domain resource position of the second signal are FDM, as follows:

[0569] The frequency domain resource location of the LP-ZP-RS and the frequency domain resource location FDM of the second signal may specifically be:

[0570] There is a first offset between the frequency domain starting position of the LP-ZP-RS and the frequency domain starting position, the frequency domain center position, or the frequency domain ending position of the second signal;

[0571] LP-ZP-RS is mapped to at least one RE / RB continuously or discontinuously (with a fixed mapping pattern) in a fixed frequency domain. It can also be mapped to at least one RE / RB continuously or discontinuously based on a specific mapping pattern and with the starting position as a reference.

[0572] The time domain position of the LP-ZP-RS and the time domain position TDM of the second signal can be specifically:

[0573] The time domain starting position of the LP-ZP-RS is offset from the time domain starting position, the time domain center position, or the time domain ending position of the second signal by a second offset, and occupies a continuous or discontinuous (fixed time domain mapping pattern) OFDM symbol / slot;

[0574] The LP-ZP-RS occupies a fixed OFDM symbol position within at least one slot in the time domain. For example, the OFDM index occupied within a slot belongs to one or more of the set {0-13}. The time domain length occupied by the LP-ZP-RS can be dynamically determined based on the length of the LP-ZP-RS, or can be determined by the protocol-specified time domain position occupied by the LP-ZP-RS (slot index within the frame, symbol index within the slot).

[0575] The LP-ZP-RS is associated with the transmission period of the second signal. One LP-ZP-RS resource can be associated with N periods of the second signal (N can be an integer or a fraction). For example, if the second signal is LP-SS, N = 2 and N = 1 / 2 are used as follows:

[0576] For example, an LP-ZP-RS is associated with two periods of LP-SS. The resource location of the LP-ZP-RS can be determined based on the time-frequency relationship, using the reception location of the first or last associated LP-SS (N > 2, either one) as a reference.

[0577] In Example 2, one LP-ZP-RS is associated with a 1 / 2 period LP-SS. The resource locations of the two LP-ZP-RSs are determined by the transmission resource location of the same LP-SS. Therefore, resource location association configuration parameters for the two LP-ZP-RSs need to be configured separately. The resource location association configuration parameters are used to determine the transmission locations of the two LP-ZP-RSs.

[0578] The LP-ZP-RS and the associated second signal have the same QCL relationship, and the QCL type can be at least one of Type A, Type B, Type C, and Type D.

[0579] The second signal may be a dedicated reception signal of LP-WUR, or an NR synchronization signal or reference signal in the related art. The second configuration parameters are described below based on different types of the second signal:

[0580] Type 1: The second signal is an NR synchronization signal (e.g., SSB), the LP-ZP-RS is associated with the resource location of the SSB signal, and the second configuration parameters may include:

[0581] A LP-ZP-RS resource location includes L LP beam directions, each beam direction is associated with at least one SSB frame (Burst) O beam directions (L LP <=total number of SSB beams in a single SSB Burst); (particularly, when a single LP-RS beam is transmitted, the time-frequency resource position of the first signal is associated with at least one SSB Burst).

[0582] The LP-ZP-RS (beam) resource and the (beam) resource associated with the second signal have the same QCL relationship, and the QCL Type may be at least one of {Type A, Type B, Type C, Type D};

[0583] There is an offset in the time domain and / or frequency domain between the resource position of the LP-ZP-RS (beam) and the resource position of the associated second signal (beam) (Toffset is the time domain offset, Foffset is the frequency domain offset).

[0584] Optionally, in this case, it may also include: configuration parameters of the first signal related to generation (signal type, signal length, number of repeated transmissions of the first signal, etc.).

[0585] Type 2: The second signal is an NR reference signal (e.g., CSI-RS), and the LP-ZP-RS is associated with the resource location of the CSI-RS signal. The second configuration parameters may include:

[0586] The LP-ZP-RS is associated with at least one CSI-RS Resource in at least one CSI-RS resource set.

[0587] The LP-ZP-RS and the associated second signal have the same QCL relationship, and the QCL Type may be at least one of {Type A, Type B, Type C, Type D}.

[0588] There is an offset in the time domain and / or frequency domain between the resource position of the LP-ZP-RS and the resource position of the associated second signal (Toffset is the time domain offset, Foffset is the frequency domain offset).

[0589] There is a first offset between the frequency domain starting position of the LP-ZP-RS and the frequency domain starting position, the frequency domain center position, or the frequency domain ending position of the second signal;

[0590] LP-ZP-RS is mapped to at least one RE / RB continuously or discontinuously (with a fixed mapping pattern) in a fixed frequency domain. It can also be mapped to at least one RE / RB continuously or discontinuously based on a specific mapping pattern and with the starting position as a reference.

[0591] Optionally, in this case, it may also include: configuration parameters of the first signal related to generation (signal type, signal length, number of repeated transmissions of the first signal, etc.).

[0592] Type 3, the second signal is a dedicated receive signal for LP-WUR, such as LP-RS, LP-WUS, and LP-SS. The following will be expanded based on the periodic low-power signal (LP-SS, LP-RSref) and the aperiodic low-power signal (LP-WUS):

[0593] The resource location information of the second reference signal (LP-SS / LP-RSref) is independently configured. For details on the configuration, see the above-mentioned method 1.

[0594] If the second signal is a periodic signal, the associated LP-ZP-RS is also a periodic signal. Similarly, if the second signal is an aperiodic signal, the associated LP-ZP-RS is also aperiodic. Specifically:

[0595] 1) The second signal is a periodic signal (e.g., LP-SS / LP-RSref): The period of the LP-RS is determined based on the period of the second signal and the number of associated signals. For example, if the transmission period of the second signal is 20 ms and the LP-ZP-RS is associated with four other signals, the transmission period of the first signal is 80 ms.

[0596] 2) The other signal is an aperiodic signal (for example, LP-WUS), and the LP-RS is also an aperiodic signal and is transmitted in association with the second signal.

[0597] The LP-ZP-RS and the associated second signal may be configured in the same resource set, and the resource index of the second signal associated with the LP-ZP-RS and / or the type of the second signal may be configured; the LP-ZP-RS and the associated second signal may also be configured in different resource sets, and the resource set index of the second signal associated with the LP-ZP-RS and / or the resource index under the resource set index and / or the type of the second signal may be configured;

[0598] The LP-ZP-RS and the associated second signal have the same QCL relationship, and the QCL Type may be at least one of {Type A, Type B, Type C, Type D}.

[0599] There is an offset in the time domain and / or frequency domain between the resource position of the LP-ZP-RS and the resource position of the associated second signal (Toffset is the time domain offset, Foffset is the frequency domain offset).

[0600] Optionally, in this case, it may also include: configuration parameters of the first signal related to generation (signal type, signal length, number of repeated transmissions of the first signal, etc.).

[0601] Taking the LP-WUS reception time-frequency resource location as an example to determine the LP-ZP-RS reception time-frequency resource location, six possible time-frequency resource location relationships between the LP-ZP-RS and LP-WUS are listed.

[0602] For example, the LP-ZP-RS and the LP-WUS are FDMed in the frequency domain, and there is a fixed offset between the LP-ZP-RS and the associated LP-WUS in the frequency domain. The frequency domain resource position of the LP-ZP-RS may be at the top and / or bottom of the frequency domain resource position of the associated LP-WUS, for example, the position relationships of the LP-WUS and the LP-ZP-RS are respectively indicated in FIG5 , FIG6 , and FIG7 ;

[0603] The LP-ZP-RS and LP-WUS are TDMed in the time domain. The LP-ZP-RS and the associated LP-WUS appear at different times. There is a fixed offset between the LP-ZP-RS and the associated LP-WUS in the time domain. For example, the position relationship between the LP-WUS and the LP-ZP-RS is indicated in Figures 8, 9, and 10, respectively.

[0604] Optionally, the LP-ZP-RS is generated in one or more of the following ways:

[0605] Method 1: The protocol stipulates that the transmission power at the determined time domain resource transmission position is 0;

[0606] Mode 2: LP-ZP-RS is an independent signal: an all-zero sequence of length N. The sequence length N can be determined by protocol agreement, configured through RRC parameters, or indicated by downlink data / control signals.

[0607] Method three: the bit position of the first information field of LP-ZP-RS for interference measurement in the first signal (the information field consists of a sequence of all 0s, the base station's transmit power in this information field is 0, and this field can be used by LP-WUR to measure the interference power of the current channel).

[0608] Optionally, the first signal may further include a second information field. The composition of the second information field can be found in the above description and will not be repeated here.

[0609] Optionally, the information field of the LP-ZP-RS and each information field bit may be based on protocol agreement, configured through RRC parameters, or indicated through downlink data / control signals.

[0610] It should be noted here that the relevant configuration parameters in Methods 1 to 3 of the LP-ZP-RS generation method can be based on protocol agreement, configured through RRC parameters, indicated by SIB messages, indicated by broadcast signals (PBCH) and / or indicated by downlink control / data signals (activation / deactivation).

[0611] It should be noted that the specific indicator parameters contained in the channel state information obtained by LP-WUR based on LP-ZP-RS can be found in the above description and will not be repeated here.

[0612] When the measured channel state information meets a preset threshold, the LP-WUS may trigger at least one of the following actions:

[0613] Action 1: triggering the second device to enter the activation state;

[0614] Action 2: triggering the second device to receive the third signal;

[0615] Action three: triggering the second device to measure and / or report the fourth signal;

[0616] The measurement information reported by the second device is carried in at least one of the following: a physical uplink shared channel, a configuration authorization resource, and a physical uplink control channel.

[0617] Action 4: triggering LP-WUR to report channel state information and / or first device capability information;

[0618] The channel state information and / or first device capability information reported by LP-WUR is carried in at least one of the following: a physical uplink shared channel, configured authorized resources, and a physical uplink control channel.

[0619] The preset threshold may be N measurement thresholds (N is greater than or equal to 1), and the above-mentioned behavior is triggered when the channel state information is higher than or lower than one or more measurement thresholds.

[0620] For example, the channel state information meeting the preset threshold means that the indicator parameter of the measured channel state information is higher than the preset threshold. The indicator parameter can be one or more of the indicator parameters B11-B16 contained in the above-mentioned channel state information, or it can be the measurement indicator defined by NR in the related technology (for example, SS-RSRP, CSI-RSRP). There can be one or more threshold values ​​corresponding to a measurement indicator.

[0621] Application Scenario 2: On-demand channel state measurement for LP-WUS reception

[0622] Step P2: The base station sends the configuration information of LP-ZP-RS and / or LP-WUS to LP-WUR according to service requirements.

[0623] Step P2: The base station simultaneously sends an LP-ZP-RS and an LP-WUS to at least one first device. The LP-ZP-RS is used to measure interference power, and the preamble sequence of the LP-WUS can be used to measure signal power. In particular, if the LP-WUS itself can simultaneously measure channel state measurement and interference power (that is, the LP-WUS signal structure includes an IM field and a preamble field, the IM field can measure interference, and the preamble field can measure channel state information, and other generation methods cannot measure interference), the base station may not configure an additional LP-ZP-RS for measuring interference power).

[0624] Optionally, both the LP-ZP-RS signal and the LP-WUS signal are exclusive receiving signals of the LP-WUR generated based on ASK and / or FSK and / or OFDM signals:

[0625] In step P3, the LP-WUR detects the Preamble sequence in the LP-WUS, determines the existence of the LP-WUS and the associated LP-ZP-RS, and obtains the current channel state information. The resource location of the LP-ZP-RS is determined based on the first configuration parameter of the LP-ZP-RS or the time-frequency position of the received Preamble sequence, and the LP-ZP-RS is received to obtain the interference power. The LP-WUR can estimate the LP-SINR of the current channel based on the channel state information (for example, signal strength) and interference power, and receive the wake-up information carried in the demodulated LP-WUS.

[0626] Optionally, the resource location of the LP-ZP-RS is determined by the reception location of the preamble field in the LP-WUS, which can be TDM and / or FDM. The specific association relationship and configuration parameters are as follows:

[0627] The frequency domain resource locations of LP-ZP-RS and preamble are FDM, which can be:

[0628] There is a first offset between the frequency domain start position of the LP-ZP-RS and the frequency domain start position, the frequency domain center position, or the frequency domain end position of the preamble domain;

[0629] LP-ZP-RS is mapped to at least one RE / RB continuously or discontinuously (with a fixed mapping pattern) in a fixed frequency domain. It can also be mapped to at least one RE / RB continuously or discontinuously based on a specific mapping pattern with a starting position as a reference.

[0630] The time domain position of the LP-ZP-RS and the time domain position of the preamble TDM can be:

[0631] The time domain starting position of the LP-ZP-RS is offset from the time domain starting position, time domain center position or time domain ending position of the preamble domain, and occupies a continuous or discontinuous (fixed time domain mapping pattern) OFDM symbol / slot;

[0632] The LP-ZP-RS occupies a fixed OFDM symbol position within at least one slot in the time domain. For example, the OFDM index occupied within a slot belongs to one or more of the set {0-13}. The time domain length occupied by the LP-ZP-RS can be dynamically determined based on the length of the LP-ZP-RS, or can be determined by the protocol-agreed time domain position occupied by the LP-ZP-RS (slot index within the frame, symbol index within the slot).

[0633] The LP-ZP-RS and the associated LP-WUS have the same QCL relationship, and the QCL type can be at least one of {Type A, Type B, Type C, Type D}.

[0634] The configuration parameters of LP-ZP-RS and LP-WUS can be found in the above description, where the reception time-frequency resource information of LP-WUS used as a reference is configured independently, and the resource position of LP-ZP-RS is determined based on the resource position configuration parameter of LP-WUS and the second configuration parameter indicating the association relationship between the preamble and the time-frequency resource position of LP-ZP-RS;

[0635] Optionally, the configuration method of LP-ZP-RS and corresponding configuration parameters can be found in the above description and will not be repeated here.

[0636] It should be noted that the specific indicator parameters contained in the channel state information obtained by LP-WUR based on LP-ZP-RS can be found in the above description and will not be repeated here.

[0637] When the measured channel state information meets a preset threshold, the LP-WUS may trigger at least one of the following actions:

[0638] Action 1: triggering the second device to enter the activation state;

[0639] Action 2: triggering the second device to receive the third signal;

[0640] Action three: triggering the second device to measure and / or report the fourth signal;

[0641] Action 4: Trigger LP-WUR to report channel status information and / or first device capability information.

[0642] The preset threshold may be N measurement thresholds (N is greater than or equal to 1), and the above-mentioned behavior is triggered when the channel state information is higher than or lower than one or more measurement thresholds.

[0643] The indicator parameter of the measured channel state information is higher than the preset threshold. The indicator parameter may be one or more indicator parameters contained in the above-mentioned channel state information, or it may be a measurement indicator defined by NR in the related technology (for example, SS reference signal received power (SS-RSRP), CSI reference signal received power (CSI-RSRP)). There may be one or more threshold values ​​corresponding to a measurement indicator.

[0644] Application Scenario 3: Conflict between First Signal and NR Signal Resource Locations

[0645] Step K1: When the time-frequency resource position for the base station to send the first signal conflicts with the resource position for sending the NR signal, the base station decides to cancel the sending of the first signal and / or the sending of the NR signal based on the base station implementation or predefined rules.

[0646] The first signal is a dedicated reception signal of LP-WUR, for example, LP-RS, LP-WUS, LP-SS.

[0647] The generation method and mapping method of the first signal are described above and will not be repeated here.

[0648] Optionally, the NR signal may be, for example, a synchronization signal (SSB), a reference signal (CSI-RS), or a downlink control / downlink data signal (PDCCH, PDSCH).

[0649] Predefined rules include one or more of the following:

[0650] When the transmission positions of the first signal and the NR signal conflict, the base station cancels the transmission of the first signal;

[0651] When the sending locations of the first signal and the NR signal conflict, the base station sends the first signal at the resource overlapping location and sends the NR signal and / or the first signal at other resource locations.

[0652] When the sending locations of the first signal and the NR signal conflict, the base station sends the third signal at the resource overlapping location and sends the first signal and / or NR signal at other resource locations.

[0653] When the transmission positions of the first signal and the NR signal conflict, the base station cancels the transmission of the NR signal;

[0654] Step K2, LP-WUR determines the resource location where the signal conflict occurs based on the configuration parameters of the first signal and the configuration parameters of the NR signal, and LP-WUR determines whether to receive the first signal and / or report the measurement information of the first signal based on implementation or predefined rules.

[0655] NR signals can be, for example, synchronization signals (SSB), reference signals (CSI-RS), and downlink control / data signals (PDCCH, PDSCH).

[0656] The configuration related to the reception of the first signal is detailed in the above description and will not be repeated here.

[0657] The predefined rules are detailed in step K1. The corresponding actions of LP-WUR are as follows:

[0658] When the predefined rule defines cancellation of transmission of the first signal, the LP-WUR does not receive the first signal at the time-frequency resource position of the first signal and / or does not report measurement information of the first signal;

[0659] When the predefined rule defines that the resource overlap portion of the first signal and the NR signal is used to send the third signal, the LP-WUR does not receive the first signal in the resource overlap portion, and only receives the first signal in the resource non-overlap portion and / or the reported measurement information is only obtained based on the resource non-overlapping resource measurement;

[0660] When the first signal is sent in the case of resource conflict defined in the predefined rule, the LP-WUR receives the first signal at the time-frequency resource location of the first signal and / or reports measurement information at the resource location for reporting measurement information.

[0661] It should be noted that at least one embodiment of the present disclosure is aimed at LP-WUR without an FFT module, does not support OFDM signal demodulation, and cannot distinguish the information characteristics of the RE level. A method for generating and sending a zero-power signal based on RB / OFDM symbols is proposed. LP-WUR does not need to perform FFT to receive this signal, and can directly measure the channel state information in the time domain. In addition, in the related art, CSI-ZP-RS is a UE-Specific reference signal in the connected state. When LP-WUR is in the IDLE state, a Cell-specific or UE (group)-Specific reference signal is required to measure the channel state; the zero-power signal designed in the embodiment of the present disclosure is Cell-specific or UE (group)-Specific, and can also be used to measure the channel state of LP-WUR in RRC_IDLE / INACTIVE mode. The embodiment of the present disclosure solves the problem of the conflict between the resource position of the zero-power signal and the transmission resource position of the specific signal by defining how to transmit the signal when the resource position of the zero-power signal conflicts with the transmission resource position of the specific signal, thereby ensuring the reliability of signal transmission.
