AI Technical Summary
In the prior art, the delay of the terminal wakes up from an extremely low power consumption state to a normal reception NR signal sent by the base station is large, resulting in an increase in the access delay.
The resource locations of the first and second devices receiving signals are determined through the first configuration information and the second configuration information sent by the network device. Specifically, it includes determining that the first device wakes up the second device based on the time domain and frequency domain location of the first signal, and determining that the second device accesses the network device or transmits the signal or data based on the reception window of the second signal and search space configuration information.
This reduces the delay from the terminal to access the base station after wake-up from an extremely low power consumption state, and reduces the energy consumption overhead during the device's waiting for signals.

Abstract
Description
Method, device and storage medium for determining low-power access or transmission
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims priority to Chinese patent application number 202311014882.2, filed on August 11, 2023, entitled “Method, device and storage medium for determining low-power access or transmission”, which is incorporated herein by reference in its entirety. Technical Field
[0003] The present disclosure relates to the field of communication technologies, and in particular to a method, device, and storage medium for determining low-power access or transmission. Background Art
[0004] The terminal energy-saving topic proposes the concepts of low-power wake-up signal (LP-WUS) and low-power wake-up receiver (LP-WUR), which are applied on the basis of existing energy-saving technologies to further reduce the terminal energy consumption level. When the terminal is in the Radio Resource Control (RRC) idle mode and the base station and the terminal have no business transmission, the terminal's main radio (MR), which consumes more energy, is turned off, allowing the terminal to enter an ultra-deep sleep state. At the same time, the LP-WUR device is turned on to receive the low-power wake-up signal (LP-WUS) sent by the base station to determine whether it is necessary to wake up the MR and base station for communication. This can greatly save the terminal's power consumption.
[0005] However, the access delay incurred by a MR waking up from a low-power state to receiving NR signals from the base station includes the transition delay from the ultra-low-power state to the active state (400ms, 800ms), as well as the resynchronization delay after the MR enters the active state (3 to 10 SSB cycles). Compared with existing terminal energy-saving methods, the access delay of the terminal waking up again after entering the ultra-low-power state is significantly increased.
[0006] Therefore, how to reduce the delay of a terminal accessing a base station after being in an extremely low power consumption state has become an urgent problem to be solved in this field.

[0447] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.
[0448] FIG1 is a flow chart of a method for determining low-power access or transmission provided by an embodiment of the present disclosure, as shown in FIG1 , including:
[0449] Step 101: Determine, based on first configuration information sent by a network device, a resource location at which a first device receives a first signal; the first signal is used to instruct the first device to wake up a second device;
[0450] Specifically, after receiving the first configuration information sent by the network device, the resource location at which the first device receives the first signal is determined according to the first configuration information, that is, at which time-frequency resource locations the first device receives the first signal. The time-frequency resource location here is specifically divided into two aspects: time domain resources and frequency domain resources. According to the different granularities of dividing network resources, the units of the time domain resource location can be determined to include system frames, time slots, and symbols, etc., and the units of the frequency domain resource location include Hertz Hz. Of course, the time-frequency resource location can also be expressed in the form of resource units (Resource Element, RE), resource groups (Resource Element Group, REG), and resource blocks (Resource Block, RB). The first device includes a low power receiver (Low Power Wake Up Receiver, LP-WUR).
[0451] At the resource location where the first signal is received, the first device receives the first signal sent by the network device, where the first signal is used to instruct the first device to wake up the second device, that is, after receiving the first signal, the first device can wake up one or more second devices associated or connected to the first device, and these second devices associated or connected to the first device are in a dormant state. The first signal can be a Low Power Wake Up Signal (LP-WUS), and the second device includes a Main Radio (MR).
[0452] Step 102: Determine the resource location where the second device receives the second signal based on the second configuration information sent by the network device and the resource location where the first device receives the first signal; the second signal is used for the awakened second device to access the network device, or to transmit signals or data between the network device.
[0453] Specifically, in addition to receiving the first configuration signal sent by the network device, the second configuration information sent by the network device will also be received. The second configuration information can configure the offset between the resource location for receiving the second signal and the resource location for receiving the first signal, the configuration parameters for periodically receiving the second signal, the receiving window parameter configuration for receiving the second signal, etc.
[0454] The second configuration information, combined with the resource location for receiving the first signal, further determines the resource location at which the second device receives the second signal. The second device receives the second signal at the resource location for receiving the second signal. The second signal enables the awakened second device to access the network device or perform data or service signal transmission with the network device. The first and second devices may be the same terminal or different terminals.
[0455] The method for determining low-power access or transmission provided by the embodiment of the present disclosure uses first configuration information and second configuration information configured by a network device, and determines the resource location of the first signal based on the first configuration information, and dynamically determines the resource location of the second signal based on the second configuration information, thereby reducing the delay of waiting for the second signal after the second device wakes up, and at the same time reducing the energy consumption overhead of the second device during the period of waiting for the second signal.
[0456] In some embodiments, before determining the resource location of the first device for receiving the first signal based on the first configuration information sent by the network device, the method further includes:
[0457] Reporting receiving capability information to the network device, where the receiving capability information is used by the network device to determine the first configuration information and / or the second configuration information;
[0458] The receiving capability information includes one or more of the following:
[0459] a type of receiver of the first device;
[0460] sensitivity of a receiver of the first device;
[0461] a transition delay of the second device from a very low power state to an active state;
[0462] Version information of the communication standard supported by the second device.
[0463] Specifically, before receiving the first configuration information and the second configuration information sent by the network device, the first device and / or the second device may report receiving capability information, and the first device and the second device may learn the receiving capability information of each other.
[0464] The receiving capability information here specifically includes: one or more of: the type of the first device's receiver, the sensitivity of the first device's receiver, the transition delay of the second device from an extremely low power consumption state to an active state, and the version information of the communication standard supported by the second device. The first device can obtain the receiving capability information of the second device associated or connected to it, and then report it to the network device together with its own receiving capability information; or the second device can obtain the receiving capability information of the first device associated or connected to it, and then report it to the network device together with its own receiving capability information; or the first device reports its own receiving capability information to the network device, and the second device reports its own receiving capability information to the network device, and the network device determines the first configuration information to be sent to the first device and the second configuration information to be sent to the second device. The receiver type of the first device, such as RF-based or baseband-based; the receiver sensitivity of the first device, which primarily indicates the sensitivity of the first device's receiver to signals, expressed in dBm; the transition delay of the second device from an extremely low power state to an active state, which varies from device to device, such as 400ms for some devices and 800ms for others; and the version of the communication standard supported by the second device, which primarily indicates whether the second device supports Rel16, Rel17, or higher-level communication standards. Since the first device and the second device are associated, the first device can determine which second device or devices to wake up after receiving the first signal.
[0465] In some embodiments, the first configuration information includes one or more of the following:
[0466] a time domain position of the first signal;
[0467] The frequency domain position or frequency domain synchronization grid of the first signal;
[0468] The symbol length occupied by the first signal;
[0469] A mapping method of the first signal in the time-frequency resources;
[0470] the number of repeated transmissions or the maximum number of transmissions of the first signal;
[0471] the number of second devices associated with the first signal;
[0472] the number of second device groups associated with the first signal;
[0473] The number of resource locations of the second signal associated with the first signal.
[0474] Specifically, the first configuration information is used to configure relevant parameters for receiving the first signal, including one or more of the following:
[0475] The time domain position of the first signal indicates the distribution of the first signal at multiple specific locations in the time domain. This can be periodic or aperiodic, configured according to the multiple specific locations configured with this parameter. You can also configure the specific starting and ending positions, and duration of the first signal within each period of the time domain. This can be understood as transmitting the first signal in segments or repeatedly within a period.
[0476] The frequency domain position of the first signal indicates the distribution of the first signal at multiple specific locations in the frequency domain. This can be periodic or aperiodic, configured according to the multiple specific locations configured by this parameter. The specific starting and ending frequencies, first bandwidth, and other parameters of the first signal within each frequency domain period can also be configured. This can be understood as transmitting the first signal in parallel across multiple frequency bands within a single period, or transmitting the first signal repeatedly across multiple frequency bands within a single period.
[0477] The frequency domain grid of the first signal and the frequency domain position of the first signal play the same role, but are expressed in different ways, indicating the central frequency point and corresponding bandwidth of the first signal distribution.
[0478] The symbol length occupied by the first signal indicates the total number of symbols occupied by a physical resource unit of a signal.
[0479] The mapping manner of the first signal in the time-frequency resources indicates the mapping relationship between each first signal and the time-frequency resources.
[0480] The number of repeated transmissions or the maximum number of transmissions of the first signal indicates the number of repeated transmissions of the first signal sent by the network device, or the maximum number of transmissions of the first signal sent by the network device. It can be understood as the number of repeated transmissions or the maximum number of transmissions that the network device can send the first signal. After the number of repeated transmissions or the maximum number of transmissions is reached, the network side no longer sends the first signal.
[0481] The number of second devices associated with the first signal is primarily used to configure how many second devices are associated with the first device. This configuration information determines how many second devices are awakened by the first device receiving the first signal. The specific second devices awakened are determined based on the identifiers of the second devices associated with the first device. For the first device, its associated second devices are already configured.
[0482] The number of second device groups associated with the first signal is primarily used to configure how many second device groups are associated with the first device. This configuration information determines how many second device groups are awakened by the first device receiving the first signal. The specific second device groups awakened are determined based on the identifiers of the second devices associated with the first device. For the first device, its associated second device groups are already configured. Furthermore, the number of second devices associated with the first signal and the number of second device groups associated with the first signal can be used together to configure which second device(s) within which second device groups are associated with the first device.
[0483] The number of second signal resource locations associated with the first signal, and the first signal can wake up the second device and / or second device group on the associated second signal resources.
[0484] The first configuration information can dynamically determine the resource location at which the first device receives the first signal through a variety of configuration parameters, which is more flexible than the existing fixed configuration.
[0485] In some embodiments, the time domain position of the first signal includes one or more of the following:
[0486] a receiving period of the first signal;
[0487] A time domain starting receiving position of the first signal within a receiving cycle;
[0488] A time domain termination receiving position of the first signal within a receiving cycle;
[0489] a first duration of the first signal in a receiving cycle;
[0490] The frequency domain position of the first signal includes one or more of the following:
[0491] a receiving period of the first signal;
[0492] A frequency domain starting receiving position of the first signal within a receiving cycle;
[0493] The frequency domain end receiving position of the first signal within one receiving cycle;
[0494] A first bandwidth in the frequency domain of the first signal within one receiving cycle.
[0495] Specifically, the time domain position of the first signal can be represented by any one or more parameters of the receiving period of the first signal, the time domain starting receiving position, the ending receiving position and the first duration within one receiving period. Among them, in the time domain, the time domain starting receiving position within one receiving period can be represented as the time domain starting receiving moment within one receiving period, the time domain ending receiving position within one receiving period can be represented as the time domain ending receiving moment within one receiving period, and the first duration within one receiving period can be represented as the duration of receiving the first signal within one receiving period, and the first duration is usually less than the receiving period of the first signal.
[0496] The frequency domain position of the first signal can be represented by any one or more parameters of the receiving period of the first signal, the starting receiving position of the frequency domain of the first signal within one receiving period, the ending receiving position of the frequency domain of the first signal within one receiving period, and the first bandwidth of the frequency domain of the first signal within one receiving period. Specifically, in the frequency domain, the starting receiving position of the frequency domain within one receiving period can be represented as the starting receiving frequency point of the frequency domain within one receiving period, the ending receiving position of the time domain within one receiving period can be represented as the ending receiving frequency point of the time domain within one receiving period, and the first bandwidth of the frequency domain within one receiving period can be represented as the frequency range of receiving the first signal within one receiving period.
[0497] Through the above-mentioned second configuration information, appropriate second configuration information can be configured for the second device according to the conversion delay of the second device, thereby effectively reducing the waiting time of the second device. For example, a longer reference time domain offset can be configured for a second device with a longer conversion delay, and a shorter reference time domain offset can be configured for a second device with a shorter conversion delay, thereby adapting to second devices with different conversion delays.
[0498] In some embodiments, the second configuration information includes one or more of the following:
[0499] A reference time domain offset, used to represent a time domain offset between a resource location corresponding to a reference point and a resource location at which the second device receives the second signal; the resource location corresponding to the reference point is the resource location at which the first device receives the first first signal or the resource location at which the first device receives the last first signal;
[0500] First search space configuration information is used to configure a first period for receiving the second signal, a starting receiving position offset and a second duration within a single first period, and a type of the second signal;
[0501] Second search space configuration information is used to configure a second period for receiving the second signal, a starting receiving position offset and a third duration within a single second period, and a type of the second signal;
[0502] Receiving window configuration information, used to configure any one of a receiving window start time, a receiving window duration, and a receiving window end time, or a combination thereof; the receiving window is used to receive the second signal;

[0504] Specifically, the second configuration information may be configured using one or more of the following parameters:
[0505] The reference time domain offset represents the time domain offset between the resource position corresponding to the reference point and the resource position for receiving the second signal; here, the resource position corresponding to the reference point is the resource position for receiving the first first signal, or the resource position for receiving the last first signal.
[0506] The first search space configuration information is existing search space configuration information, which is used to configure the first period for receiving the second signal, the starting receiving position offset and the second duration within a single first period, and the type of the second signal.
[0507] The second search space configuration information is newly added, distinct from the first search space configuration information. The second search space configuration information has a different name, and the values of certain configuration parameters in the second search space configuration information differ from the values of the same configuration parameters in the first search space configuration information. The second search space configuration parameters are used to configure the second period for receiving the second signal, the offset of the starting reception position within a single second period, the third duration, and the type of the second signal. Furthermore, the aggregation level and a more granular starting reception symbol position for receiving the second signal can also be configured.
[0508] The receiving window configuration information is used to configure any one of the following: the receiving window start time, the receiving window duration, and the end time, or a combination thereof; the receiving window is used to receive the second signal; that is, a time window configured for receiving the second signal. Unlike the first search space configuration information or the second search space configuration information, the receiving window configuration information is not periodic. Specifically, the specific duration of the receiving window can be determined by configuring the receiving window start time and end time, or the starting time and duration, or the duration and end time. The receiving window duration here can be expressed in different time units.
[0509] The maximum number of times the second signal is received is configured in the second configuration information to prevent the second device from being in an awake state all the time, waiting to receive the second signal sent by the network device, which consumes a lot of power;
[0510] The number of times the second signal is received is mainly used to configure the second device to receive the second signal a fixed number of times, that is, the second signal will no longer be received after the number of consecutive receptions reaches this value.
[0511] In some embodiments, the duration of the receiving window is a plurality of unit durations determined in units of system frames, time slots, symbols or paging cycles.
[0512] Specifically, the duration of the receiving window may be a system frame, a time slot, a symbol or a paging cycle as a unit, and may be multiple system frames, multiple time slots, multiple symbols or multiple paging cycles.
[0513] In some embodiments, the second search space configuration information includes one or more of the following:
[0514] a period for receiving the second signal;
[0515] an offset of a starting receiving position for receiving the second signal;
[0516] a third duration of receiving the second signal;
[0517] A starting received symbol within a single receiving second signal cycle;
[0518] Aggregation level;
[0519] The downlink control information format is used to determine the type of the second signal.
[0520] Specifically, the configuration parameters of the second search space configuration information include any one or a combination of the following:
[0521] The period for receiving the second signal, i.e., the second period, represents a specific value of periodically receiving the second signal;
[0522] an offset of a starting receiving position for receiving the second signal, that is, an offset from a starting moment of each second period;
[0523] a third duration for receiving the second signal, that is, a time length for receiving the second signal in each second period, and the time length is less than a value of the second period;
[0524] A starting reception symbol in a single second signal reception period, that is, a starting reception symbol at a resource location for receiving the second signal in each second period;
[0525] Aggregation Level (AL), used to determine reception information of the second signal;
[0526] The downlink control information format, that is, the format of the downlink control information (DCI), such as DCI Format0_0 and DCI Format1_0, is used to determine the type of the second signal.
[0527] In some embodiments, determining the resource location at which the second device receives the second signal based on the second configuration information sent by the network device and the resource location at which the first device receives the first signal includes:
[0528] Determining a starting resource position of the receiving window based on a receiving window starting time configured in the receiving window configuration information included in the second configuration information and a resource position corresponding to the reference point;
[0529] Determining an end resource position of the receiving window based on a starting resource position of the receiving window and a duration of the receiving window, or based on a starting resource position of the receiving window and an end time of the receiving window configured in the receiving window configuration information included in the second configuration information;
[0530] Based on the second search space configuration information included in the second configuration information, a resource location at which the second device receives the second signal is determined between the starting resource location and the ending resource location of the receiving window.
[0531] Specifically, according to the second configuration information and the resource location for receiving the first signal, there may be multiple methods for determining the resource location for receiving the second signal, one of which is that the second configuration information includes receiving window configuration information and second search space configuration information.
[0532] According to the receiving window configuration information included in the second configuration information, the receiving window starting position and the receiving window duration configured in the receiving window configuration information, or the receiving window starting position and the receiving window ending position are acquired.
[0533] Determine the starting resource position of the receiving window according to the receiving window starting time configured in the receiving window configuration information and the resource position corresponding to the reference point;
[0534] Then, according to the starting resource position of the receiving window and the duration of the receiving window, the ending resource position of the receiving window is determined, or according to the starting resource position of the receiving window and the ending resource position of the receiving window, the ending resource position of the receiving window is determined;
[0535] Between the starting resource position and the ending resource position of this receiving window, the resource position at which the second device receives the second signal is determined according to the second search space configuration parameters included in the second configuration information.
[0536] In some embodiments, determining the resource location at which the second device receives the second signal based on the second configuration information sent by the network device and the resource location at which the first device receives the first signal includes:
[0537] Determining, based on the first search space configuration information and / or the second search space configuration information included in the second configuration information, a candidate resource location for receiving the second signal;
[0538] Determining, in the candidate resource locations, a paging frame in which a starting resource location for receiving the second signal is located, based on a first rule and a first input parameter, as a target paging frame; the first input parameter being one or more of a system frame in which the resource location corresponding to the reference point is located, the paging cycle T, the number N of paging frames in the paging cycle, and a reference time domain offset in the second configuration information;

[0540] Based on the starting reception symbol position set firstPDCCH-MonitoringOccasionOfPO configured in the first system message SIB1, a paging opportunity matching the index value corresponding to the symbol position for receiving the second signal is determined, and the paging opportunity is used as the resource position for receiving the second signal.
[0541] Specifically, in addition to determining the resource location for receiving the second signal based on the receiving window configuration information and the second search space configuration information in the second configuration information, the candidate resource location for receiving the second signal can also be determined based on the first search space configuration information and / or the second search space configuration information configured in the second configuration information; and then, among these candidate resource locations, the resource location for the second device to receive the second signal is determined according to the corresponding preset rules.
[0542] Obtain the relevant parameters required in the preset rules, namely the first input parameter of the first rule and the second input parameter of the index calculation rule. The first input parameter and the second input parameter here can be configured through any one or more of the first system information block (System Information Block1, SIB1), non-access stratum (Non-Access Stratum, NAS) message, wireless access network (wireless access network, RAN) message and radio resource control (Radio Resource Control, RRC) message; wherein the first input parameter is one or more of the paging frame where the resource location corresponding to the reference point is located, the paging cycle T, the number of paging frames in the paging cycle N, and the reference time domain offset in the second configuration information; the second input parameter is one or more of the identifier of the second device, the number of paging frames in the paging cycle N, and the total number of paging opportunities Ns in a single paging frame.
[0543] Using the resource location where the first first signal is received and the resource location where the last first signal is received as the resource location corresponding to the reference point, and further determining the paging frame where the resource location corresponding to the reference point is located;
[0544] The first rule is used in combination with the first input parameter to determine the paging frame where the starting resource position of the second signal is located as the target paging frame; the first rule is used to define any one or more of the following relationships:
[0545] A correspondence between the paging frame where the resource position corresponding to the reference point is located and the paging frame where the second signal starting resource position is located;
[0546] The correspondence between the paging cycle T and the paging frame where the second signal starting resource position is located;
[0547] The correspondence between the number N of paging frames in the paging cycle and the paging frame where the second signal starting resource position is located;
[0548] The correspondence between the time domain offset in the second configuration information and the paging frame where the second signal starting resource position is located.
[0549] An index value corresponding to the second signal is determined by using an index calculation rule in combination with the second input parameter. The index calculation rule is used to define any one or more of the following relationships:
[0550] a correspondence between an identifier of the second device and an index value corresponding to a symbol position at which the second signal is received;
[0551] a correspondence between the number N of paging frames in a paging cycle and an index value corresponding to a symbol position at which the second signal is received;
[0552] The corresponding relationship between the total number Ns of paging opportunities in a single paging frame and the index value corresponding to the symbol position for receiving the second signal.
[0553] Obtain the set firstPDCCH-MonitoringOccasionOfPO of starting reception symbol positions configured in the first system message SIB1, where the set of starting reception symbol positions is used to represent the corresponding relationship between the paging opportunities to be monitored and the index value corresponding to the symbol position for receiving the second signal;
[0554] In the set of starting reception symbol positions, use the index value corresponding to the symbol position for receiving the second signal to perform a search or matching to determine the paging opportunity that matches the index value corresponding to the symbol position for receiving the second signal, and use the paging opportunity as the resource position for receiving the second signal.
[0555] In some embodiments, the first rule satisfies the following formula: (LP-WUS_SFN + LP-WUS_offset + SFN) mod T = T div N;
[0556] Where LP-WUS_SFN represents the system frame where the resource position corresponding to the reference point is located, LP-WUS_offset represents the reference time domain offset, SFN represents the paging frame where the starting resource position of the second signal is located, mod() represents taking the modulus, T represents the discontinuous reception period or paging period, and N represents the number of paging frames within the paging period.
[0557] The paging period T can be configured through the SIB1 message, RRC message, NAS message, or RAN message. If the paging period T configured through the SIB1 message, RRC message, NAS message, or RAN message includes multiple values, for example, the value of the paging period T configured by the SIB1 message is T1, the value of the paging period T configured by the RRC message is T2, the value of the paging period T configured by the NAS message is T3, and the value of the paging period T configured by the RAN message is T4, and T2 < T1 < T3 < T4, determine the minimum value T2 among these values as the value of the paging period T, that is, the value of the paging period T is T2. The number N of paging frames within the paging period and the total number Ns of paging opportunities in a single paging frame can be configured through the SIB1 message.
[0558] In some embodiments, the index calculation rule satisfies the following formula: i_s = floor(UE_ID / N) mod Ns;
[0559] Among them, UE_ID represents the identifier of the second device; N represents the number of paging frames in the paging cycle, floor() represents rounding down, mod() represents modulo, Ns is the number of a single paging frame in the paging opportunity; i_s represents the index value corresponding to the symbol position of receiving the second signal.
[0560] In some embodiments, determining the resource location at which the second device receives the second signal based on the second configuration information sent by the network device and the resource location at which the first device receives the first signal includes:
[0561] Determining, based on the first search space configuration information and / or the second search space configuration information included in the second configuration information, a candidate resource location for receiving the second signal;
[0562] In the candidate resource positions, determining a target paging frame for receiving the second signal by the second device based on the resource position at which the first device receives the first signal and the reference time domain offset in the second configuration information;
[0563] In the target paging frame, resource locations for receiving the second signal are determined in sequence according to the second period in the second search space configuration information in the second configuration information.
[0564] Specifically, in addition to the above method for determining the resource location at which the second device receives the second signal, the following method may also be used for determination:
[0565] According to the first search space configuration information and / or the second search space configuration information configured in the second configuration information, the candidate resource locations for receiving the second signal are determined; then, among these candidate resource locations, the resource location at which the first device receives the first signal and the second search space configuration information in the second configuration information are used to determine the resource location at which the second device receives the second signal.
[0566] In the candidate resource locations, a target paging frame for the second device to receive the second signal is determined based on the resource location at which the first device receives the first signal and the reference time domain offset in the second configuration information.
[0567] In the target paging frame, the resource locations for the second device to receive the second signal are sequentially determined according to the second period in the second search space configuration information. The resource locations for the second device to receive the second signal are determined in units of symbols, that is, the specific symbol position in the target paging frame at which the second signal is received.
[0568] In some embodiments, the method further comprises:
[0569] If the second configuration information sent by the network device further includes a fourth duration associated with the first signal for receiving the second signal, determining, based on the second configuration information, a resource location for the second device to receive the second signal;
[0570] The determining, based on the second configuration information, a resource location at which the second device receives the second signal includes:
[0571] Obtain a first period in the first search space configuration information in the second configuration information;
[0572] In each first period, sequentially determining, according to the reference time domain offset in the second configuration information, a resource location at which the second device receives the second signal;
[0573] Determine, based on the fourth duration and the reference time domain offset in the second configuration information, and the resource location for receiving the target second signal, a resource location for receiving the at least one first signal by the first device;
[0574] The fourth duration is an integer multiple of discontinuous reception cycles or paging cycles for receiving the second signal.
[0575] Specifically, in addition to determining the resource location for the second device to receive the second signal based on the second configuration information and the resource location for receiving the first signal, the resource location for the second device to receive the second signal can also be directly determined based on the second configuration information, and then the resource location for receiving the first signal can be determined based on the time domain offset between the resource location corresponding to the reference point and the resource location for receiving the second signal, thereby first receiving the first signal at the resource location for receiving the first signal, and then receiving the second signal at the resource location for receiving the second signal on the second device.
[0576] In order to directly determine the resource location for the second device to receive the second signal based on the second configuration information, the corresponding second configuration information also needs to configure: a fourth duration associated with the first signal for receiving the second signal, and the fourth duration is an integer multiple of the paging cycle for receiving the second signal.
[0577] When the second configuration information includes a fourth duration for receiving the second signal associated with the first signal, acquiring a first period for receiving the second signal of the first search space configuration information in the second configuration information;
[0578] In each first period, sequentially determining a resource location for receiving the second signal according to the time domain offset in the second configuration information;
[0579] Based on the fourth duration and the time domain offset in the second configuration information, as well as the resource locations for receiving the target second signal, the resource locations for all first devices to receive the first signal are determined. Accordingly, when sending the second signal, the network device further selects one or more resource locations that meet the receiving capability information reported by the first device and / or the second device, and sends the second signal to the second device.
[0580] In some embodiments, the method further comprises:
[0581] receiving the first signal at a resource location for receiving the first signal;
[0582] If the number of repeated transmissions or the maximum number of transmissions of the first signal included in the first configuration information is reached, the first signal is no longer received.
[0583] Specifically, the first device receives the first signal at the resource location for receiving the first signal, and at the same time counts whether the actual number of consecutive receptions of the first signal reaches the number of repeated transmissions or the maximum number of transmissions of the first signal configured in the first configuration information. If reached, the first signal is no longer received. If not reached, the first device continues to receive the first signal until the configured number of repeated transmissions or the maximum number of transmissions of the first signal is reached.
[0584] In some embodiments, the method further comprises:
[0585] receiving the second signal at a resource location for receiving the second signal;
[0586] If the maximum number of times the second signal included in the second configuration information is received is reached and the second signal is not received, the second device enters a sleep state.
[0587] Specifically, the second device receives the second signal at the resource location for receiving the second signal, and counts whether the consecutive number of times the second signal is not received reaches a preset maximum number of receptions. If so, the second device enters the sleep state again.
[0588] In some embodiments, the type of the first configuration information includes one or more of the following: Cell-specific configuration information, UE-specific configuration information, and UE group-specific configuration information; the type of the second configuration information includes one or more of the following: Cell-specific configuration information, UE-specific configuration information, and UE group-specific configuration information; the Cell-specific configuration information, the UE-specific configuration information, and the UE group-specific configuration information are carried in RRC signaling, dynamic signaling, or broadcast signaling.
[0589] Specifically, the type of the first configuration information is divided into any one or more of Cell-specific configuration information, UE-specific configuration information and UE group-specific configuration information; when the first configuration information type is Cell-specific configuration information, all first devices within the coverage of the same cell can adopt the first configuration information; when the first configuration information type is UE-specific configuration information, only specific first devices can receive the first configuration information, and which specific first devices are determined based on the UE-specific configuration information; when the first configuration information type is UE group-specific configuration information, only multiple specific first devices can receive the first configuration information, and which specific first devices can be determined by grouping according to first devices with the same capabilities. Regardless of whether the type of the first configuration information is any one or more of Cell-specific configuration information, UE-specific configuration information, and UE group-specific configuration information, it can be carried in RRC signaling, dynamic signaling or broadcast signaling, that is, it can be configured through RRC signaling, dynamic signaling or broadcast signaling. Dynamic signaling includes downlink data signals or downlink control signals. Downlink control signals can be signals of the Physical Downlink Control Channel (PDCCH), and downlink data signals can be signals of the Physical Downlink Shared Channel (PDSCH). Broadcast signaling includes signaling of the System Information Block (SIB) and the Physical Broadcast Channel (PBCH). System Information Blocks (SIBs) include multiple types, such as SIB1, SIB2, ..., SIB12, etc.
[0590] Similarly, the types of the second configuration information are also divided into three types: Cell-specific configuration information, UE-specific configuration information and UE group-specific configuration information; the functions, effects and configuration methods corresponding to different types are the same as those of the first configuration information, and will not be repeated here.
[0591] In some embodiments, the first configuration information and / or the second configuration information is activated through dynamic signaling, or the first configuration information and / or the second configuration information is deactivated through dynamic signaling.
[0592] Specifically, the first configuration information and / or the second configuration information can also be activated or deactivated via dynamic signaling. This can be understood as if multiple sets of first configuration parameters are configured, and any one or more of them can be activated or deactivated via dynamic signaling. Similarly, multiple sets of second configuration parameters can be configured, and any one or more of them can be activated or deactivated via dynamic signaling. Furthermore, dynamic signaling can be used to activate or deactivate one or more parameters within the first configuration parameters, and similarly, dynamic signaling can be used to activate or deactivate one or more parameters within the second configuration parameters.
[0593] In some embodiments, the method further comprises:
[0594] Determining the type of the received second signal based on the type of the second signal in the second configuration information and the resource location of receiving the second signal; the type of the second signal includes a paging opportunity or a paging advance indication;
[0595] Determining whether to configure paging advance indication configuration information based on third configuration information sent by the network device; the paging advance indication configuration information is used to indicate a type of the second signal that the second device preferentially receives;
[0596] If the paging advance indication configuration information has been configured, the second device preferentially receives the paging advance indication at a resource location where the type of the second signal is a paging advance indication, and then determines, based on the information carried by the paging advance indication, whether to receive a paging message at a resource location of a paging opportunity associated with the paging advance indication; or
[0597] If the paging advance indication configuration information is not configured, the second device receives a paging message at a resource location where the type of the second signal is a paging opportunity.
[0598] Specifically, the above-mentioned second configuration information also configures the type of the second signal. Therefore, while determining the resource location for receiving the second signal, the type of the received second signal can also be determined, where the type of the second signal includes a paging opportunity and a paging advance indication, that is, the type of the received second signal may be any one or a combination of a paging opportunity and a paging advance indication.
[0599] In addition, the network device will also send third configuration information, and it is necessary to determine which type of second signal the second device should preferentially receive based on the third configuration information.
[0600] Further determining whether to configure paging advance indication configuration information based on the third configuration information sent by the network device;
[0601] If the paging advance indication configuration information has been configured, that is, the network device indicates that the second signal of the paging advance indication type is preferentially received, then the second device preferentially receives the paging advance indication at the resource location of the second signal of the paging advance indication type, and then determines whether to receive the paging message at the resource location of the paging opportunity associated with the paging advance indication based on the information carried by the paging advance indication.
[0602] If the paging advance indication configuration information is not configured, the second device directly receives the paging message at a resource location where the second signal type is a paging opportunity.
[0603] Similarly, for the network device, if the paging advance indication configuration information is configured in the third configuration information, the network device preferentially sends the paging advance indication, and carries the paging opportunity associated with it in the paging advance indication message, and sends a paging message to the second device at the corresponding paging opportunity;
[0604] If the paging advance indication configuration information is not configured in the third configuration information, the network device directly sends a paging message to the second device at the resource location of the paging opportunity.
[0605] In some embodiments, the method further comprises:
[0606] Determining the type of the received second signal based on the type of the second signal in the second configuration information and the resource location of receiving the second signal; the type of the second signal includes a paging opportunity or a paging advance indication;
[0607] Determining, based on third configuration information sent by the network device, whether a skip parameter is configured and / or whether the configured skip parameter has been activated; the skip parameter is used to indicate whether to skip a paging advance indication opportunity and / or to indicate a type of the second signal that the second device preferentially receives;
[0608] If the skip parameter has been configured and / or the configured skip parameter has been activated, the second device receives a paging message at a resource location of the second signal type being a paging opportunity; or,
[0609] If the skip parameter is not configured and / or the configured skip parameter is not activated, the second device preferentially receives the paging advance indication at the resource location where the type of the second signal is a paging advance indication, and then determines whether to receive the paging message at the resource location of the paging opportunity associated with the paging advance indication based on the information carried by the paging advance indication.
[0610] Specifically, the above-mentioned second configuration information also configures the type of the second signal. Therefore, while determining the resource location for receiving the second signal, the type of the received second signal can also be determined, where the type of the second signal includes a paging opportunity and a paging advance indication, that is, the type of the received second signal may be any one or a combination of a paging opportunity and a paging advance indication.
[0611] In addition, the network device also sends third configuration information to the second device, and the second device determines which type of second signal to receive preferentially based on the third configuration information.
[0612] Further, based on the third configuration information sent by the network device, it is determined whether the skip parameter is configured and / or whether the configured skip parameter is activated; there are three situations:
[0613] Case 1: Whether to configure the skip parameter;
[0614] If the skip parameter is configured, it means that the skip parameter is effective. The skip parameter is used to indicate whether to skip the paging advance indication opportunity; that is, if the skip parameter is configured, it means that the paging prompt indication opportunity needs to be skipped; if the skip parameter is not configured, it means that the paging prompt indication opportunity does not need to be skipped.
[0615] Case 2: Whether the skip parameter is configured and whether the configured skip parameter is activated
[0616] Configuring the skip parameter only indicates the existence of this configuration item, not its effectiveness. Whether this parameter is effective depends on whether the configured skip parameter is activated. Configuring the skip parameter indicates that the network or terminal has this capability, but whether it is effective depends on whether the skip parameter is activated. If the skip parameter is configured and activated, it indicates that paging prompt indication opportunities need to be skipped. If the skip parameter is configured but not activated, it indicates that paging prompt indication opportunities do not need to be skipped.
[0617] Case 3: Is the configured skip parameter activated?
[0618] Similar to Case 2, "skip parameter activation" means the skip parameter has been configured and activated, while "skip parameter inactivation" means the skip parameter has been configured but not activated. For the corresponding functions and effects, refer to Case 3. The configured skip parameter can be activated or deactivated through dynamic signaling.
[0619] Furthermore, if a skip parameter is configured, the configured skip parameter is activated, or the skip parameter is configured and activated, the second device receives a paging message at a resource location of the second signal of a type of paging opportunity;
[0620] On the contrary, if the skip parameter is not configured or the configured skip parameter is not activated, the second device preferentially receives the paging advance indication at the resource location where the type of the second signal is a paging advance indication, and then determines whether to receive the paging message at the resource location of the paging opportunity associated with the paging advance indication based on the information carried by the paging advance indication.
[0621] In some embodiments, the third configuration information includes one or more of the following:
[0622] Paging advance indication configuration information, used to indicate the type of the second signal that the second device preferentially receives;
[0623] The skip parameter is used to indicate whether to skip the paging advance indication opportunity, and / or to indicate the type of the second signal that the second device preferably receives.
[0624] Specifically, the third configuration information is determined by the network device based on the reported receiving capability information, that is, based on the version information of the communication standard supported by the second device included in the receiving capability information. The third configuration information includes one or more of the following: paging advance indication configuration information and skip parameters.
[0625] The paging advance indication configuration information is used to indicate the type of the second signal that the second device preferentially receives;
[0626] The skip parameter is used to indicate whether to skip the paging advance indication opportunity and / or to indicate the type of the second signal that the second device preferentially receives. There are multiple configurations for this parameter:
[0627] Case 1: If the skip parameter is configured, it means that the parameter is effective, that is, it is used to indicate the type of the second signal that the second device preferentially receives or to indicate to skip the paging advance indication opportunity; if the skip parameter is not configured, it means that the parameter is not effective, that is, the second device receives the second signal according to the existing process or indicates not to skip the paging advance indication opportunity.
[0628] Case 2: Configuring the skip parameter does not necessarily mean it's effective. Activation is required for the configured skip parameter to take effect. Activation can be achieved using an indicator bit in the skip parameter or through dynamic signaling. Specifically, the activation of the configured skip parameter can be indicated by a 0 or 1 indicator bit in the skip parameter, or by dynamic signaling.
[0629] The method for determining low-power access or transmission provided by the embodiment of the present disclosure uses first configuration information and second configuration information configured by a network device, and determines the resource location of the first signal based on the first configuration information, and dynamically determines the resource location of the second signal based on the second configuration information, thereby reducing the delay of waiting for the second signal after the second device wakes up, and at the same time reducing the energy consumption overhead of the second device during the period of waiting for the second signal.
[0630] FIG2 is a second flow chart of a method for determining low-power access or transmission provided by an embodiment of the present disclosure. As shown in FIG2 , the method includes:
[0631] Step 201: Determine first configuration information and / or second configuration information based on the acquired receiving capability information or service requirements;
[0632] The receiving capability information includes one or more of the following:
[0633] a type of receiver of the first device;
[0634] sensitivity of a receiver of the first device;
[0635] a transition delay of the second device from a very low power state to an active state;
[0636] version information of a communication standard supported by the second device;
[0637] The service demand includes one or more of the following: paging demand, data transmission demand, and signal transmission demand.
[0638] Specifically, the network device may determine the first configuration information and / or the second configuration information according to the receiving capability information reported by the first device and / or the second device, or service requirements.
[0639] There is an association or connection relationship between the first device and the second device, and the first device and the second device can obtain each other's receiving capability information, that is, the first device can obtain the receiving capability information of the second device and report it to the network device together with the receiving capability information of the first device; or, the second device can obtain the receiving capability information of the first device and report it to the network device together with the receiving capability information of the second device; or, the first device reports its own receiving capability information to the network device, and the second device reports its own receiving capability information to the network device, and the first device and the second device are associated.
[0640] Then the network devices can all know that the reported receiving capability information includes: the type of the first device's receiver, the sensitivity of the first device's receiver, the transition delay of the second device from the extremely low power consumption state to the active state, and one or more of the version information of the communication standard supported by the second device.
[0641] Alternatively, the first configuration information and / or the second configuration information is determined according to a service requirement including any one of a paging requirement, a data transmission requirement, and a signal transmission requirement.
[0642] The method for determining low-power access or transmission provided by the embodiment of the present disclosure is that the network device flexibly determines the first configuration information and / or the second configuration information through the reported receiving capability information or service requirements, which is used for the first device to determine the resource location of the first signal based on the first configuration information, and / or for the second device to dynamically determine the resource location of the second signal based on the second configuration information, thereby reducing the delay of the second device waiting for the second signal after waking up, and at the same time reducing the energy consumption overhead of the second device during the period of waiting for the second signal.
[0643] In some embodiments, determining the first configuration information and / or the second configuration information based on the acquired receiving capability information or service requirements includes:
[0644] If the receiving capability information reported by the target device is received, determining the first configuration information and / or the second configuration information to be sent to the target device based on the receiving capability information reported by the target device; or,
[0645] If the receiving capability information reported by the target device is not received, determining the first configuration information and / or the second configuration information based on the service requirements;
[0646] The target device is at least one of all first devices and / or all second devices within the coverage range of the network device.
[0647] Specifically, there are multiple first devices and / or second devices within the coverage of the network device, and there is an association relationship between the first device and the second device. Any first device or second device within the coverage of the network device is used as the target device.
[0648] If the network device receives the receiving capability information reported by the target device, then based on the reported receiving capability information, the first configuration information and / or the second configuration information to be sent to the target device is determined. For example, after the first device learns the receiving capability information of the second device associated with it, the receiving capability information reported by the first device includes its own receiving capability information and the receiving capability information of the second device, and the network device determines the first configuration information and the second configuration information respectively based on the receiving capability information; or, the first device reports its own receiving capability information or the second device reports its own receiving capability information, so that the receiving capability information received by the network device only includes the receiving capability information of the first device or the receiving capability information of the second device, thereby determining the first configuration information based on the receiving capability information of the first device, or determining the second configuration information based on the receiving capability information of the second device.
[0649] If the network device does not receive the receiving capability information reported by the target device, the first configuration information and the second configuration information are determined based on service requirements, such as paging requirements, data transmission requirements, and signal transmission requirements.
[0650] In some embodiments, determining the first configuration information and / or the second configuration information to be sent to the target device based on the receiving capability information reported by the target device includes:
[0651] Determining, based on the type of the first device's receiver and / or the sensitivity of the first device's receiver included in the receiving capability information, first configuration information to be sent to the first device; the first configuration information is used by the first device to determine a resource location for receiving a first signal; the first signal is used to instruct the first device to wake up the second device;
[0652] Based on the transition delay of the second device from an extremely low power consumption state to an activated state included in the receiving capability information, second configuration information to be sent to the second device is determined; the second configuration information is used by the second device to determine the resource location for receiving the second signal.
[0653] Specifically, if the received receiving capability information includes the type of the receiver of the first device and / or the sensitivity of the receiver of the first device, the network device determines the first configuration information to be sent to the first device based on the receiving capability information; after the first configuration information is sent to the first device, the first device determines the resource location for receiving the first signal based on the first configuration information, and the first signal instructs the first device to wake up the second device.
[0654] If the received receiving capability information includes a transition delay of the second device from the very low power consumption state to the active state, the network device determines, based on the receiving capability information, second configuration information to be sent to the second device. The second device determines, based on the second configuration information, a resource location for receiving the second signal.
[0655] Here, the first device and the second device are associated with each other.
[0656] In some embodiments, the first configuration information includes one or more of the following:
[0657] a time domain position of the first signal;
[0658] The frequency domain position or frequency domain synchronization grid of the first signal;
[0659] The symbol length occupied by the first signal;
[0660] A mapping method of the first signal in the time-frequency resources;
[0661] the number of repeated transmissions or the maximum number of transmissions of the first signal;
[0662] the number of second devices associated with the first signal;
[0663] the number of second device groups associated with the first signal;
[0664] The number of resource locations of the second signal associated with the first signal.
[0665] Specifically, the first configuration information is determined by the network device and is used to configure relevant parameters for receiving the first signal, and specifically includes one or more of the following:
[0666] The time domain position of the first signal indicates the distribution of the first signal at multiple specific locations in the time domain. This can be periodic or aperiodic, configured according to the multiple specific locations configured with this parameter. You can also configure the specific starting and ending positions, and duration of the first signal within each period of the time domain. This can be understood as transmitting the first signal in segments or repeatedly within a period.
[0667] The frequency domain position of the first signal indicates the distribution of the first signal at multiple specific locations in the frequency domain. This can be periodic or aperiodic, configured according to the multiple specific locations configured by this parameter. The specific starting and ending frequencies, first bandwidth, and other parameters of the first signal within each frequency domain period can also be configured. This can be understood as transmitting the first signal in parallel across multiple frequency bands within a single period, or transmitting the first signal repeatedly across multiple frequency bands within a single period.
[0668] The frequency domain grid of the first signal and the frequency domain position of the first signal play the same role, but are expressed in different ways, indicating the central frequency point and corresponding bandwidth of the first signal distribution.
[0669] The symbol length occupied by the first signal indicates the total number of symbols occupied by a physical resource unit of a signal.
[0670] The mapping manner of the first signal in the time-frequency resources indicates the mapping relationship between each first signal and the time-frequency resources.
[0671] The number of repeated transmissions or the maximum number of transmissions of the first signal indicates the number of repeated transmissions of the first signal sent by the network device, or the maximum number of transmissions of the first signal sent by the network device. It can be understood as the number of repeated transmissions or the maximum number of transmissions that the network device can send the first signal. After the number of repeated transmissions or the maximum number of transmissions is reached, the network side no longer sends the first signal.
[0672] The number of second devices associated with the first signal is primarily used to configure how many second devices are associated with the first device. This configuration information determines how many second devices are awakened by the first device receiving the first signal. The specific second devices awakened are determined based on the identifiers of the second devices associated with the first device. For the first device, its associated second devices are already configured.
[0673] The number of second device groups associated with the first signal is primarily used to configure how many second device groups are associated with the first device. This configuration information determines how many second device groups are awakened by the first device receiving the first signal. The specific second device groups awakened are determined based on the identifiers of the second devices associated with the first device. For the first device, its associated second device groups are already configured. Furthermore, the number of second devices associated with the first signal and the number of second device groups associated with the first signal can be used together to configure which second device(s) within which second device groups are associated with the first device.
[0674] The number of second signal resource locations associated with the first signal, and the first signal can wake up the second device and / or second device group on the associated second signal resources.
[0675] The first configuration information can dynamically determine the resource location at which the first device receives the first signal through a variety of configuration parameters, which is more flexible than the existing fixed configuration.
[0676] In some embodiments, the time domain position of the first signal includes one or more of the following:
[0677] a receiving period of the first signal;
[0678] A time domain starting receiving position of the first signal within a receiving cycle;
[0679] A time domain termination receiving position of the first signal within a receiving cycle;
[0680] a first duration of the first signal in a receiving cycle;
[0681] The frequency domain position of the first signal includes one or more of the following:
[0682] a receiving period of the first signal;
[0683] A frequency domain starting receiving position of the first signal within a receiving cycle;
[0684] The frequency domain end receiving position of the first signal within one receiving cycle;
[0685] A first bandwidth in the frequency domain of the first signal within one receiving cycle.
[0686] Specifically, the time domain position of the first signal can be represented by any one or more parameters of the receiving period of the first signal, the time domain starting receiving position, the ending receiving position and the first duration within one receiving period. Among them, in the time domain, the time domain starting receiving position within one receiving period can be represented as the time domain starting receiving moment within one receiving period, the time domain ending receiving position within one receiving period can be represented as the time domain ending receiving moment within one receiving period, and the first duration within one receiving period can be represented as the duration of receiving the first signal within one receiving period, and the first duration is usually less than the receiving period of the first signal.

Specifically, in the frequency domain, the starting receiving position of the frequency domain within one receiving period can be represented as the starting receiving frequency point of the frequency domain within one receiving period, the ending receiving position of the time domain within one receiving period can be represented as the ending receiving frequency point of the time domain within one receiving period, and the first bandwidth of the frequency domain within one receiving period can be represented as the frequency range of receiving the first signal within one receiving period.

[0694] Specifically, the second configuration information may be configured using one or more of the following parameters:
[0695] The time domain offset between the resource position corresponding to the reference point and the resource position for receiving the second signal; here, the resource position corresponding to the reference point is the resource position for receiving the first first signal, or the resource position for receiving the last first signal.
[0696] The first search space configuration information is existing search space configuration information, which is used to configure the first period for receiving the second signal, the starting receiving position offset and the second duration within a single first period, and the type of the second signal.
[0697] The second search space configuration information is newly added, distinct from the first search space configuration information. The second search space configuration information has a different name, and the values of certain configuration parameters in the second search space configuration information differ from the values of the same configuration parameters in the first search space configuration information. The second search space configuration parameters are used to configure the second period for receiving the second signal, the starting reception position offset and third duration within a single second period, and the type of the second signal. Furthermore, the aggregation level and the starting reception symbol for receiving the second signal at a finer granularity can also be configured.

Unlike the first search space configuration information or the second search space configuration information, the receiving window configuration information is not periodic. Specifically, the specific duration of the receiving window can be determined by configuring the receiving window start time and end time, or the starting time and duration, or the duration and end time. The receiving window duration here can be expressed in different time units.
[0699] The maximum number of times the second signal is received is configured in the second configuration information to prevent the second device from being in an awake state all the time, waiting to receive the second signal sent by the network device, which consumes a lot of power.
[0700] The number of times the second signal is received is mainly used to configure the second device to receive the second signal a fixed number of times, that is, the second signal will no longer be received after the number of consecutive receptions reaches this value.
[0701] In some embodiments, the duration of the receiving window is a plurality of unit durations determined in units of system frames, time slots, symbols or paging cycles.
[0702] Specifically, the duration of the receiving window may be a system frame, a time slot, a symbol or a paging cycle as a unit, and may be multiple system frames, multiple time slots, multiple symbols or multiple paging cycles.

Regardless of whether the type of the first configuration information is any one or more of Cell-specific configuration information, UE-specific configuration information, and UE group-specific configuration information, it can be carried in RRC signaling, dynamic signaling or broadcast signaling, that is, it can be configured through RRC signaling, dynamic signaling or broadcast signaling. Dynamic signaling includes downlink data signals or downlink control signals. Downlink control signals can be signals of the Physical Downlink Control Channel (PDCCH), and downlink data signals can be signals of the Physical Downlink Shared Channel (PDSCH). Broadcast signaling includes signaling of the System Information Block (SIB) and the Physical Broadcast Channel (PBCH). System Information Blocks (SIBs) include multiple types, such as SIB1, SIB2, ..., SIB12, etc.
[0705] In some embodiments, the method further comprises:
[0706] Sending dynamic signaling to the first device and / or the second device;
[0707] The dynamic signaling is used to activate the first configuration information and / or the second configuration information, or the dynamic signaling is used to deactivate the first configuration information and / or the second configuration information.
[0708] Specifically, the network device may activate the first configuration information and / or the second configuration information, or deactivate the first configuration information and / or the second configuration information by sending dynamic signaling to the first device and / or the second device.
[0709] In some embodiments, the method further comprises:
[0710] determining third configuration information based on version information of a communication standard supported by the second device included in the received capability information;
[0711] The third configuration information is used to configure the type of the second signal that the second device preferentially receives;
[0712] The type of the second signal includes a paging advance indication or a paging opportunity;
[0713] Send the third configuration information to the first device and / or the second device.
[0714] Specifically, the network device receives the reception capability information reported by the first device and / or the second device, determines third configuration information, and configures the second device to prioritize receiving a second signal type, where the second signal type includes a paging advance indication and a paging opportunity. Specifically, the network device configures the second device to prioritize receiving a paging advance indication or a paging opportunity. The determined third configuration information is then sent to the first device and / or the second device.
[0715] In some embodiments, the third configuration information includes one or more of the following:
[0716] Paging advance indication configuration information, used to indicate the type of the second signal that the second device preferentially receives;
[0717] The skip parameter is used to indicate whether to skip the paging advance indication opportunity, and / or to indicate the type of the second signal that the second device preferably receives.
[0718] Specifically, the third configuration information is determined by the network device based on the acquired receiving capability information, that is, the third configuration information is determined based on the version information of the communication standard supported by the second device included in the receiving capability information.

[0720] The skip parameter is used to indicate whether to skip the paging advance indication opportunity and / or to indicate the type of the second signal that the second device preferentially receives. There are multiple configurations for this parameter:
[0721] Case 1: If the skip parameter is configured, it means that the parameter is effective, that is, it is used to indicate the type of the second signal that the second device preferentially receives or to indicate to skip the paging advance indication opportunity; if the skip parameter is not configured, it means that the parameter is not effective, that is, the second device receives the second signal according to the existing process or indicates not to skip the paging advance indication opportunity.
[0722] Case 2: Configuring the skip parameter does not necessarily mean it's effective. Activation is required for the configured skip parameter to take effect. Activation can be achieved using an indicator bit in the skip parameter or through dynamic signaling. Specifically, the activation of the configured skip parameter can be indicated by a 0 or 1 indicator bit in the skip parameter, or by dynamic signaling.
[0723] The method for determining low-power access or transmission provided by the embodiment of the present disclosure is that the network device flexibly determines the first configuration information and / or the second configuration information through the reported receiving capability information or service requirements, which is used for the first device to determine the resource location of the first signal based on the first configuration information, and / or for the second device to dynamically determine the resource location of the second signal based on the second configuration information, thereby reducing the delay of the second device waiting for the second signal after waking up, and at the same time reducing the energy consumption overhead of the second device during the period of waiting for the second signal.
[0724] In order to more clearly illustrate the method for determining low-power access or transmission provided by the embodiment of the present disclosure, the technical solution of the embodiment of the present disclosure is further introduced through several specific examples below.
[0725] Initial state: The first device is in an ultra-deep sleep state, and the second device is in a dormant state.
[0726] Example 1: Determine the resource location for receiving the second signal by receiving the window configuration information in the second configuration information.
[0727] Step 1: The base station side configures first configuration information and second configuration information. The first configuration information is used to determine the sending and receiving resource location of the first signal (LP-WUS signal), and the second configuration information is used to determine the sending and receiving resource location of the second signal (PO / PEI-O).
[0728] 1.1 The first configuration information and the second configuration information may be UE (group)-specific configuration information or cell-specific configuration information based on the receiver capabilities reported by the first device and / or the second device. The first configuration information and the second configuration information may also be cell-specific configuration information for all receiver capabilities determined based on service requirements.
[0729] The first device includes a Low Power Wake Up Receiver (LP-WUR); the second device includes a Main Radio (MR).
[0730] The receiver reception capability reported by the first device and / or the second device includes at least one of the following:

[0735] The type of the first configuration information includes UE (group) specific configuration information or Cell specific configuration information, and the type of the second configuration information includes UE (group) specific configuration information or Cell specific configuration information.
[0736] Cell-specific configuration information can be configured through any one or more of RRC signaling configuration, dynamic signaling and broadcast signaling, where dynamic signaling includes PDCCH, PDSCH, etc.; broadcast signaling includes SIB X, PBCH, etc.; in addition, dynamic signaling can be used to activate certain Cell-specific configuration information or certain Cell-specific configuration information, or to deactivate certain Cell-specific configuration information or certain Cell-specific configuration information.
[0737] Similarly, the UE group-specific configuration information and the Cell-specific configuration information can be configured through any one or more of RRC signaling configuration, dynamic signaling and broadcast signaling, and activated and / or deactivated through dynamic signaling.
[0738] 1.2 The first configuration information is used to determine the reception of the first signal (LP-WUS). The LP-WUS included in the first device is a dedicated signal received by the LP-WUR. The first configuration information may include one or more of the following:
[0739] a receiving period of the first signal in the time domain and / or frequency domain;
[0740] The starting receiving position, duration, and ending receiving position of the first signal within the period;
[0741] The symbol length occupied by the first signal;
[0742] The number of repeated transmissions of the first signal / the maximum number of transmissions;
[0743] The frequency domain position or frequency domain synchronization grid of the first signal;
[0744] The number of second devices associated with the first signal.
[0745] the number of second device groups associated with the first signal;
[0746] The number of resource locations of the second signal associated with the first signal.
[0747] 1.3 The second configuration information is used to determine the reception of the second signal, which is a dedicated signal received by the second device. The second signal includes PO / PEI-O, and the second configuration information may include at least one of the following:
[0748] 1) Existing search space (SS) configuration information, used to configure the period for receiving the second signal, the starting receiving position offset, and the duration;
[0749] 2) New search space (New SS) configuration information, used to configure the period, starting reception position offset, and duration for receiving the second signal. The difference between the new search space configuration parameters and the existing search space configuration parameters lies in the name. For example, the existing search space configuration information is named PO-SS or PEI-SS, while the new search space configuration information is named PO-SS-Rel-18 or PEI-SS-Rel-18.
[0750] 3) First receiving window configuration parameters: receiving the second signal within the first receiving window and not receiving the second signal outside the first receiving window. The relevant configuration parameters may include at least one of the following:
[0751] The starting time of the first receiving window may be based on a time domain offset LP-WUS_offset between a resource location for receiving the first or last first signal and a resource location for receiving the second signal;
[0752] The duration of the first receiving window can be M1 frames, M1 time slots, M1 symbols or N paging cycles, where M1 is a positive integer and can be pre-configured by RRC; N is a positive integer and can be determined by the maximum number of received paging times pre-configured by RRC or predefined by the protocol.
[0753] The end time of the first receiving window may be a specific frame, a time slot, or a symbol.
[0754] 4) A time domain offset LP-WUS_offset between a resource location for receiving the first or last first signal and a resource location for receiving the second signal.
[0755] 5) The number of times the second signal is received or the maximum number of times it is received.
[0756] Step 2: The base station side sends a first signal (LP-WUS) carrying wake-up information according to the paging requirement to instruct the first device to wake up the second device, so that the second device is in a state where it can receive paging information and / or PEI, and determines the first receiving window for receiving the second signal according to the second configuration information.
[0757] Step 3: The first device (LP-WUR) wakes up the second device (MR) after receiving the first signal (LP-WUS) carrying the wake-up information. The second device determines the starting position of the first receiving window based on the receiving position of the first signal (LP-WUS), and determines the resource location for receiving the second signal (PO / PEI) within the first receiving window and receives it.
[0758] 3.1 The second device determines the resource location of the first receiving window according to the receiving location of the first signal:
[0759] The first receiving position and / or the last receiving position of the first signal is the resource position of the reference point, and the resource position offset from the resource position of the reference point by LP-WUS_offset is used as the starting position of the first window;
[0760] Then, according to the configuration parameters of the first receiving window in the second configuration information and the starting position of the first window, determine the duration and end position of the first receiving window;
[0761] 3.2 The second device determines, within the first receiving window, a receiving resource location for the second signal based on the existing search space (SS) configuration information and / or the new search space (New SS) configuration information in the second configuration information. As shown in FIG3 , FIG3 is a schematic diagram of the resource location distribution for receiving the second signal within the receiving window provided by an embodiment of the present disclosure.
[0762] Step 4: Determine the type of the second signal to be received preferentially according to the third configuration information;
[0763] According to the type of the second signal configured in the second configuration information and the resource location for receiving the second signal determined in the above steps, the type of the second signal received at the resource location for receiving the second signal can be determined; the type of the second signal includes a paging opportunity and a paging advance indication.
[0764] and determining, based on the third configuration information sent by the network device, whether paging advance indication configuration information is configured in the third configuration information;
[0765] If the paging advance indication configuration information is configured, the second device preferentially receives the paging advance indication at a resource location where the second signal type is the paging advance indication, and determines, based on information carried by the paging advance indication, whether to receive a paging message at a resource location of a paging opportunity associated with the paging advance indication;
[0766] If the paging advance indication configuration information is not configured, the second device receives a paging message at a resource location where the type of the second signal is a paging opportunity.
[0767] Alternatively, based on the third configuration information sent by the network device, determining whether the skip parameter PEI_skip_enable is configured in the third configuration information, and / or whether the configured skip parameter PEI_skip_enable is activated;
[0768] There are two cases here:
[0769] Case 1: Whether the skip parameter is configured, that is, whether the skip parameter is effective. For example, if the skip parameter is configured, it means that the skip parameter has been activated; if the skip parameter is not configured, it means that the skip parameter is not activated;
[0770] Case 2: Whether the skip parameter is configured does not determine whether the skip parameter is effective. If the skip parameter is configured, you must activate the configured skip parameter to ensure that it takes effect.
[0771] If the skip parameter has been configured, indicating that the skip parameter has taken effect, or if the skip parameter has been configured and the configured skip parameter has been activated, indicating that the skip parameter has taken effect, or if the configured skip parameter has been activated, equivalent to the case where the skip parameter has been configured and the configured skip parameter has been activated, then the second device receives the paging message at a resource location where the type of the second signal is a paging opportunity;
[0772] If the skip parameter is not configured, it means that the skip parameter is not effective; or, the skip parameter is configured and the configured skip parameter is not activated, which also means that the skip parameter is not effective; or, the configured skip parameter is not activated, which is equivalent to the case where the skip parameter is configured and the configured skip parameter is not activated, then the second device preferentially receives the paging advance indication at the resource location where the type of the second signal is a paging advance indication, and then determines whether to receive the paging message at the resource location of the paging opportunity associated with the paging advance indication based on the information carried by the paging advance indication.
[0773] Example 2: Determining the resource location where the second device receives the second signal based on the second configuration information and the resource location where the first signal is received
[0774] Step 1: The base station side configures first configuration information and second configuration information, the first configuration information is used to determine the sending and receiving resource location of the first signal (LP-WUS), and the second configuration information is used to determine the sending and receiving resource location of the second signal (PO / PEI-O).
[0775] Step 2: The base station side sends a first signal (LP-WUS) carrying wake-up information according to the paging requirement to instruct the first device to wake up the second device. The second device is in a state where it can receive the second signal. The time domain offset of the resource location for sending the second signal from the resource location for sending the first signal is LP-WUS_offset.
[0776] Step 3: The second device determines the resource location for receiving the second signal (PEI and / or PO) based on the resource location for receiving the first signal, and may adopt one of the following methods:
[0777] Method 1: The second device determines the resource location for receiving the second signal based on the resource location for receiving the first signal and the new search space configuration information in the second configuration information; as shown in Figure 4, Figure 4 is one of the resource location distribution diagrams for receiving the first signal and the second signal provided in an embodiment of the present disclosure.
[0778] First, determining a starting system frame (starting paging frame) for receiving the second signal, and then determining a symbol position for receiving the second signal in the starting paging frame, including:
[0779] Based on the received SIB1 message, obtain one or more of the discontinuous reception cycle or paging cycle T, the number N of paging frames in the paging cycle, and the total number Ns of paging opportunities in a single paging frame;
[0780] Obtaining a time domain offset in the second configuration information, that is, obtaining a time domain offset between a resource location of a reference point and a resource location for receiving the second signal, where the resource location of the reference point is a resource location at which the first device receives the first first signal or a resource location at which the last first signal is received;
[0781] Determine the system frame where the resource location corresponding to the reference point is located;
[0782] Determining that the first input parameter is any one or more of a discontinuous reception cycle or a paging cycle T, the number N of paging frames in the paging cycle, a system frame in which a resource location corresponding to a reference point is located, and a time domain offset in the second configuration information;
[0783] Based on a first rule and a first input parameter, a system frame containing a starting resource location for receiving the second signal is determined as a target paging frame. The system frame containing a paging opportunity is a paging frame, and the system frame containing a starting resource location for receiving the second signal is correspondingly determined as the target paging frame. The first rule is used to define a correspondence between different input parameters and the system frame containing the starting resource location for receiving the second signal.
[0784] In the target paging frame, based on the index calculation rule and the second input parameter, the target index value corresponding to the symbol position of receiving the second signal is determined; the second input parameter here includes one or more of the identifier of the second device, the number N of paging frames in the paging cycle, and the total number Ns of paging opportunities in a single paging frame; the index calculation rule is used to define the relationship between different input parameters and the index values corresponding to the symbol position of receiving the second signal.
[0785] According to the starting reception symbol position set firstPDCCH-MonitoringOccasionOfPO configured in SIB1, a paging opportunity matching the target index value is determined; and the paging opportunity is used as a resource position for receiving the second signal.
[0786] In some embodiments, the first rule satisfies the formula: (LP-WUS_SFN+LP-WUS_offset+SFN) mod T=T div N;
[0787] Wherein, LP-WUS_SFN represents the system frame (SFN) where the resource location of the reference point is located, and the resource location of the reference point is the resource location where the first / last first signal is received;
[0788] LP-WUS_offset represents a time domain offset between a resource location corresponding to a reference point and a resource location at which the second device receives the second signal, and is configured through the second configuration information;
[0789] SFN represents the paging frame where the second signal start reception resource location is located;
[0790] T represents the discontinuous reception (DRX) cycle, enhanced discontinuous reception (eDRX) cycle, or paging cycle, which can be configured through any one or more of SIB1 messages, RRC signaling, and NAS signaling;
[0791] N represents the number of paging frames in a paging cycle, which is configured through the SIB1 message.
[0792] In some embodiments, the formula corresponding to the index calculation rule is: i_s=floor(UE_ID / N) mod Ns;
[0793] Among them, UE_ID represents the identifier of the second device; N represents the number of paging frames in the paging cycle, floor() represents rounding down, mod() represents modulo, Ns is the number of a single paging frame in the paging opportunity; i_s represents the target index value corresponding to the symbol position of receiving the second signal.
[0794] The starting reception position of the Paging Early Indication (PEI) associated with the Paging Occasion (PO) is determined by the pei-FrameOffset and firstPDCCH-MonitoringOccasionOfPEI-O configuration parameters in the existing SIB1 message.
[0795] Method 2: If no SIB1 message is received, the resource location for receiving the second signal is determined according to the new search space configuration information in the second configuration information and the resource location for receiving the first signal.
[0796] A time domain offset LP-WUS_offset between a starting resource position for receiving the second signal and a resource position for receiving the first / last first signal, where the unit of LP-WUS_offset may be a frame / time slot / symbol;
[0797] Determine a system frame where a resource location for receiving the first signal is located as the first system frame;
[0798] In the first system frame, the resource location for receiving the second signal is determined in sequence according to the second period configured by the second search space configuration information in the second configuration information and the time domain offset in the second configuration information.
[0799] The second search space configuration information is primarily used to configure the periodic determination of the time slot position or symbol position for receiving the second signal within a single system frame. Whether the time slot position or symbol position is determined is based on the granularity of the resource position for receiving the first signal. If the resource position for receiving the first signal is in time slots, then the resource position for receiving the second signal is also in time slots. If the resource position for receiving the first signal is in symbols, then the resource position for receiving the second signal is also in symbols. This determines the resource position for receiving the second signal.
[0800] Step 4: Determine the type of the second signal to be received preferentially according to the third configuration information; the specific implementation process is the same as that in Example 1 and will not be repeated here.
[0801] Example 3: When the fourth duration associated with the first signal and used to receive the second signal is further configured in the second configuration information, the resource location for receiving the second signal is determined directly according to the second configuration information.
[0802] Step 1: The base station side configures first configuration information and second configuration information, the first configuration information is used to determine the sending and receiving resource location of the first signal (LP-WUS), and the second configuration information is used to determine the sending and receiving resource location of the second signal (PO / PEI-O).
[0803] Step 2: The base station side sends a first signal (LP-WUS) carrying wake-up information according to the paging requirement to instruct the first device to wake up the second device. The second device is in a state where it can receive the second signal. The time domain offset of the resource location for sending the second signal from the resource location for sending the first signal is LP-WUS_offset.
[0804] Step 3: Based on the first search space configuration information in the second configuration information, first determine the resource location for receiving the second signal, and then determine the resource location for receiving the first signal based on the fourth duration associated with the first signal for receiving the second signal, specifically including:
[0805] Obtaining a first period of the first search space configuration information in the second configuration information;
[0806] In each first period, starting from the start time of each period, and in accordance with the time domain offset in the second configuration information, sequentially determining a resource location for receiving the second signal;
[0807] Based on the fourth duration and the time domain offset in the second configuration information, as well as the resource location for receiving the target second signal, the resource location for receiving all the first signals is determined; as shown in Figure 5, Figure 5 is the second schematic diagram of the resource location distribution for receiving the first signal and the second signal provided in an embodiment of the present disclosure.
[0808] The type of the above-mentioned first configuration information includes one or more of Cell-specific configuration information, UE-specific configuration information, and UE group-specific configuration information; the type of the second configuration information includes one or more of Cell-specific configuration information, UE-specific configuration information, and UE group-specific configuration information.
[0809] Step 4: Determine the type of the second signal to be received preferentially according to the third configuration information; the specific implementation process is the same as that in Example 1 and will not be repeated here.
[0810] At the resource location for receiving the first signal, the first signal is first received, and then at the resource location for receiving the second signal, the second signal is received.
[0811] When starting to receive the first signal, count whether the number of times the first signal is received reaches the number of repeated transmissions or the maximum number of transmissions of the first signal configured in the first configuration information. If so, stop receiving the first signal. If not, continue receiving the first signal.
[0812] Similarly, when starting to receive the second signal, the consecutive number of times the second signal is not received is counted to see whether the maximum number of receptions of the second signal configured in the second configuration information is reached. If reached, the second device enters the sleep state again. If not reached, the second device continues to receive the second signal.
[0813] In addition, the first device and the second device have an associated relationship and can obtain each other's receiving capability information. The receiving capability information is reported by the first device, the second device, or the first device and the second device. The network device determines the first configuration information, the second configuration information, and the third configuration information based on the received receiving capability information.
