CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Chinese Patent Application No. 202211617260.4 filed in China on December 15, 2022, the entire contents of which are incorporated herein by reference.

Technical Field

The present application belongs to the field of communication technology, and specifically relates to a wake-up signal transmission processing method, device, terminal and equipment.

Background technique

In order to reduce the receiving activity of the terminal in the standby state, the RF (radio frequency) and MODEM (baseband) modules are truly turned off, thereby greatly reducing the power consumption of communication reception. This can be achieved by introducing a near "zero" power receiver in the receiving module of the terminal. This near "zero" power receiver does not require complex RF module signal detection (such as amplification, filtering, quantization, etc.) and MODEM signal processing, but only relies on passive matching filtering and signal processing with low power consumption.

On the base station side, by triggering a wake-up signal on demand, the near-zero power receiver can be activated to receive the activation notification, thereby triggering a series of processes inside the terminal, such as turning on the RF transceiver and baseband processing modules.

In order to flexibly choose between resource overhead and coverage performance, it is necessary to consider multiple formats of wake-up signals so that the network can flexibly allocate resources for wake-up signal transmission. However, how to indicate the formats of multiple wake-up signals and enable the terminal to effectively receive the wake-up signals has become an urgent problem to be solved.

For ease of understanding, some contents involved in the embodiments of the present application are described below:

1. Low power receiver

Low-power receiver, namely Low Power Wake up Receiver (LP-WUR) or Almost Zero Power Wake Up Receiver (AZP-WUR). Its basic working principle is that the receiving end includes a first module and a second module, as shown in Figure 2. The first module is the main communication module, which is used for sending and receiving mobile communication data. The second module is a low-power receiving module (also called a low-power wake-up receiving module), which is used to receive a low-power wake-up signal (Low Power Wake Up Signal, LP-WUS), referred to as a wake-up signal (Wake Up Signal, WUS). The terminal turns on the low-power receiving module in the energy-saving state to monitor LP-WUS and turns off the main communication module. When downlink data arrives, the network side device will send a wake-up signal to the terminal. After the terminal monitors the wake-up signal through the low-power receiving module, it triggers the main communication module from off to on after a series of judgments. At this time, the low-power receiving module enters the off state (also called the sleep state) from the working state. The low-power wake-up receiving module can be turned on continuously, Or it can be turned on intermittently and receive a low-power wake-up signal when it is turned on.

2. Low power wake-up signal

In order to reduce the receiving activity of the terminal in the standby state, the RF (Radio Frequency, RF) and baseband (MODEM) modules are truly turned off, thereby greatly reducing the power consumption of communication reception. This can be achieved by introducing a near "zero" power receiver in the receiving module of the terminal. This near "zero" power receiver does not require complex RF module signal detection (such as amplification, filtering, quantization, etc.) and MODEM signal processing, but only relies on passive matching filtering and signal processing with low power consumption.

On the base station side, by triggering a wake-up signal on demand, the near-zero power receiver can be activated to receive the activation notification, thereby triggering a series of processes inside the terminal, such as turning on the RF transceiver and baseband processing modules.

This wake-up signal is usually some simple on-off keying signal, so that the receiver can obtain the wake-up notification through simple energy detection and subsequent possible sequence detection and identification processes.

3. Beacon signal

A beacon signal is a signal that is sent periodically to transmit time information. The receiving end can obtain time synchronization information by receiving the beacon signal. In some embodiments, mobility measurement or channel measurement can also be performed by receiving the beacon signal.

Normally, the Wake-up Receiver (WUR) beacon signal is transmitted using a specific Media Access Control (MAC) frame, the structure of which is shown in Figure 3. The Type Dependent Control (Type Dependent Control) of the WUR beacon MAC frame carries the information of the 5th to 16th bits of the 64-bit Timer Synchronization Function (TSF) clock of the Access Point (AP). After receiving the corresponding information bits, the user updates the user's local TSF clock according to the defined time update criteria, thereby achieving synchronization with the AP. The transmission period of the WUR beacon and the offset of the transmission start position are indicated by the operation element sent by the AP. The period is the minimum number of TSF time units between two beacon transmissions, and the start position is the number of TSF time units offset relative to TSF0. When Carrier Sense Multiple Access (CSMA) deferrals occur, the WUR beacon will be delayed in sending in the current cycle, but will still be sent in subsequent cycles according to the WUR beacon's sending cycle and the location determined by the sending start position.

The following is a detailed description of the wake-up signal transmission processing method provided by the embodiment of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

As shown in FIG4 , a wake-up signal transmission processing method according to an embodiment of the present application includes:

Step 401: The terminal obtains indication information of a wake-up signal; wherein the indication information is used to indicate a format parameter of the wake-up signal.

Here, the wake-up signal is a low power wake-up signal (LP-WUS). In this step, the terminal learns the format parameters of the wake-up signal that the first device expects the terminal to receive by acquiring indication information indicating the format parameters of the wake-up signal.

Step 402: The terminal detects and receives the wake-up signal according to the indication information.

In this step, the terminal further detects and receives a wake-up signal corresponding to the indication information according to the indication information obtained in step 401 .

In this way, according to the above steps 401 and 402, the terminal understands the format parameters of the wake-up signal that the first device expects the terminal to receive by obtaining the indication information of the wake-up signal. Thereafter, the terminal can detect and receive the wake-up signal that the first device expects the terminal to receive based on the indication information. In this way, the terminal can flexibly receive the wake-up signal to perform subsequent processing.

The first device may be a network side device, such as a base station, or a terminal, a repeater, a relay, a transmission reception point (TRP), etc. In this embodiment, the first device is taken as an example to be described as a network side device.

As an implementation method, when the network side device flexibly selects different formats to send the WUS signal, the terminal understands the format parameters of the wake-up signal that the network side device expects the terminal to receive by obtaining the indication information of the wake-up signal. After that, it can detect and receive the wake-up signal that the network side device expects the terminal to receive based on the indication information, and effectively receive the wake-up signal to perform subsequent processing.

Optionally, in this embodiment, the indication information includes at least one of the following:

A preamble of the wake-up signal;

Information carried in the first information field of the wake-up signal;

Format of non-wake-up signals;

The information carried by the second information field of the non-wake-up signal.

Among them, the indication information includes the preamble of the wake-up signal, that is, the preamble is associated with the format parameters of the wake-up signal. Specifically, different format parameters are associated with different sequence information of the preamble, and different sequence information may include at least one of the sequence elements, sequence lengths, and sequence chip rates. For example, if the preamble sequence is sequence 1 (here, sequence 1 is a combination of sequence elements used by the network-side device configuration or predefined wake-up signal preamble), the format of the wake-up signal is indicated to be format 1; the preamble sequence length is sequence length 1, indicating that the format of the wake-up signal is format 2; the chip rate of the preamble sequence is chip rate 1, indicating that the format of the wake-up signal is format 1, or the above sequence information is combined, etc. It should be noted that the association between the sequence information of the preamble and the format parameters of the wake-up signal can be predefined or configured by the network-side device.

The indication information includes information carried by the first information field on the wake-up signal, that is, a separate information field (first information field) is provided on the wake-up signal to carry information indicating the format parameters of the wake-up signal. In order not to affect the performance of the preamble, the first information field is dedicated to indicating the format parameters of the wake-up signal.

The indication information includes the format of the non-wake-up signal, that is, the format of the non-wake-up signal is associated with the format parameter of the wake-up signal. For example, the format of the non-wake-up signal is format 1, and the format of the indication wake-up signal is format 1. It should be noted that the association relationship between the format of the non-wake-up signal and the format parameter of the wake-up signal can be pre-defined or configured by the network side device.

The indication information includes information carried in the second information field of the non-wake-up signal, that is, a separate information field (second information field) is provided on the non-wake-up signal to carry information indicating the format parameters of the wake-up signal.

Therefore, optionally, the terminal obtains indication information of the wake-up signal, including at least one of the following:

The terminal receives a preamble of the wake-up signal, and determines the indication information according to sequence information of the preamble;

The terminal receives the wake-up signal, and determines the indication information according to the information carried in the first information field of the wake-up signal;

The terminal receives the non-wake-up signal, and determines the format of the wake-up signal according to the format of the non-wake-up signal;

The terminal receives the non-wake-up signal, and determines the indication information according to information carried in the second information field of the non-wake-up signal.

That is to say, when the terminal receives the preamble of the wake-up signal, it can determine the indication information from the sequence information of the preamble and obtain the format parameters of the wake-up signal indicated by the network side device. For example, the network predefines or configures a table containing the correspondence between the preamble sequence information and the WUS format parameters. After detecting a specific preamble, the terminal obtains the WUS format parameters associated with the sequence information of the preamble, and then performs subsequent detection of the payload part to detect the relevant information carried in the WUS. The different sequence information here can be the same length and different sequence content; it can also be different lengths; it can also be different sequence elements or sequences of different rates.

In addition, when the terminal receives a wake-up signal, it can determine the indication information from the information carried in the first information field of the wake-up signal, and learn the format parameters of the wake-up signal indicated by the network side device. When the terminal receives a non-wake-up signal, it can determine the indication information from the format of the non-wake-up signal, and learn the format parameters of the wake-up signal indicated by the network side device. When the terminal receives a non-wake-up signal, it can determine the indication information from the information carried in the second information field of the non-wake-up signal, and learn the format parameters of the wake-up signal indicated by the network side device.

Of course, since the indication information can be composed of at least one of the preamble code of the wake-up signal, the information carried by the first information field on the wake-up signal, the format of the non-wake-up signal, and the information carried by the second information field on the non-wake-up signal, the terminal can also combine the indication information determined by different methods for detection and reception of the wake-up signal.

In this embodiment, the network side device configures or predefines a specific signal as the above non-wake-up signal, and indicates the format parameters of the wake-up signal through its format or carried information. Optionally, the non-wake-up signal is at least one of the following:

beacon signal;

High-level signaling;

Downlink control information.

Among them, the beacon signal is a signal used to obtain time synchronization or perform mobility measurement, channel measurement, etc. When the beacon signal is used to indicate the format parameters of the wake-up signal, as shown in Figure 5, the format parameters of the wake-up signal can be indicated by carrying an extended message on the beacon signal, and the Extended message is located in the second information field. Or, it can be indicated by the association between the beacon signal format and the format parameters of the wake-up signal. Of course, it can also be indicated by the beacon signal format and the information in the second information field. For example, beacon formats are predefined to be associated with WUS formats, and specific associations include beacon format 1 being associated with WUS formats 1-1, WUS format 1-2, WUS format 1-3, and WUS format 1-4. Extended information then indicates which WUS format it is, thereby reducing bit overhead.

It should be known that when the beacon signal indicates the format parameters of the wake-up signal, the beacon signal will be sent after the terminal starts the low-power wake-up receiving module and before the terminal receives WUS. Other signals sent during this period can be indicated according to the above content and are not listed here.

Before entering the low-power wake-up receiving module, the terminal maintains normal communication. During this period, the network can configure and/or predefine WUS format parameters, which are used to indicate the format parameters of the wake-up signal through high-level signaling and downlink control information (DCI), and then transmitted to the low-power wake-up receiving module. For example, the information in the second information field of high-level signaling and downlink control information points to an index in the WUS format table (the WUS format table is configured or predefined by the network), and the corresponding WUS format parameters are obtained in the WUS format table through the index; or the information in the second information field of high-level signaling and downlink control information directly corresponds to the corresponding WUS format parameters.

Of course, the implementation of the non-wake-up signal is not limited to the above content, and can also be other signals, which are not listed here one by one.

Optionally, in this embodiment, the indication information is at least one of the following:

sequence;

Bits of information.

That is, the indication information can be a sequence and/or bit information. For example, for the information carried by the first information field on the wake-up signal, the information can be a sequence; or it can be bit information. The bit information length of the first information field is fixed, and its encoding method and code rate are different from the payload on the wake-up signal. Of course, the bit information of the first information field may not be encoded. For another example, for the information carried by the second information field on the non-wake-up signal, the information can be a specific sequence, and the correspondence between the sequence and the format parameters of the wake-up signal is determined by predefining or configuring a table; it can also be bit information, and the corresponding parameter configuration is indicated by decoding the bit information. Specifically, the indication method can be to obtain the format parameters of the wake-up signal by indicating the table index, or the corresponding bit position corresponds to a certain format parameter, and the correspondence is configured or predefined by the network.

In addition, optionally, in this embodiment, the wake-up signal content includes at least one of the following:

Preamble;

indication sequence;

Control information (control information bits).

Based on at least one of the preamble, indication sequence, and control information bits, the wake-up signal structure is shown in Figure 6-8. Of course, the wake-up signal structure can also have other forms, which are not listed here one by one.

In this embodiment, for a WUS without a preamble, the indication information indicating the format parameters of the wake-up signal can be carried on the beacon signal. For a signal containing a preamble, the format parameters of the wake-up signal can also be indicated by the preamble, or as shown in FIG9 , a first information field is set after the preamble to further transmit the indication information (Instruction) indicating the format parameters of the wake-up signal, and the indication information is a sequence or bit information.

Among them, if the indication information is a sequence, the transmitter indicates different format parameters through different sequences, and the receiver determines the WUS format parameters according to the sequence of the received indication information, then the terminal needs to perform blind detection in multiple sequences to determine the content indicated by the indication information. Compared with the indication through the preamble sequence, more different formats can be indicated. If the indication information is bit information, the receiver obtains the corresponding WUS format parameters by decoding the bit information. The bit length of the indication information is fixed, and the encoding method and code rate may be different from the payload, and channel coding may not be performed.

In this embodiment, the indication sequence and/or control information bits are the payload part of the wake-up signal. The indication sequence is also called a wake-up indication sequence, which is used to indicate that a group of UEs need to wake up. For example, if there are 8 groups of UEs that need to be woken up, the wake-up indication sequence requires 8 sequences. The content of the control information bits includes at least one of the following:

a) Whether to monitor paging signals;

b) Whether to initiate the Random Access Channel (RACH) process;

c) Timing Reference Signal (TRS) availability indication;

d) Whether to monitor the paging advance indication;

e) Paging group information update (including subgroup ID and paging cycle update of the UE, etc.);

f) Indicates whether the paging is core network (CN) paging or radio access network (RAN) paging;

g) indicating tracking area update (tracking area update);

h) System information update;

i) Switching of monitoring parameters of the Physical Downlink Control Channel (PDCCH), wherein the monitoring parameters include: whether to monitor PDCCH, the period of PDCCH monitoring, the search space to be monitored, and the search space group to be monitored;

j) Switching of Discontinuous Reception (DRX) parameters (including whether to enable the associated DRX onduration timer, update the DRX onduration start position, update the DRX cycle, update the DRX onduration length, DRX InActivityTimer length, etc.);

k) Monitoring of reference signals, high-level configuration channels, signaling, etc.;

l) Whether to initiate the RRC connection process;

m) Indication signal source, including one of the following:

i. Cell logo;

ii. TRP logo;

iii. Whether it comes from the UE, or the UE's identity;

iv. Whether it comes from a relay, or the relay's identifier.

Optionally, the wake-up signal structure includes: a sequence, an information bit, or a structure combining the two. The sequence part can be used for synchronization or information indication. The information sequence used for synchronization is usually also called preamble. The format or sequence number is small, and it does not carry information for indication, or the information that can be used for indication is limited. If the wake-up signal does not include a preamble, the wake-up signal is synchronized with the beacon signal. Of course, when the wake-up signal includes a preamble, a beacon signal can also exist to enhance synchronization performance.

In addition, optionally, in this embodiment, the format parameter includes at least one of the following:

Sequence information of the preamble of the wake-up signal;

Sequence information indicating a sequence in the wake-up signal;

A signal parameter carrying control information in the wake-up signal;

The validity period of the indication information.

In one implementation, if the wake-up signal contains a preamble, the format parameters of the wake-up signal indicated by the indication information include the sequence information of the preamble, and the format parameter information related to the payload part (i.e., the sequence information indicating the sequence and/or the signal parameter carrying the control information). If the wake-up signal contains a preamble, the format parameters of the wake-up signal indicated by the indication information include the format parameter information related to the payload part.

In this embodiment, it should be understood that the effective duration of the indication information refers to the detection and reception of the wake-up signal according to the format parameters indicated by the indication information within the effective duration. Taking the beacon signal as an example, the beacon signal does not carry specific information about the effective duration. At this time, the default effective duration is the current cycle, that is, the beacon signal only indicates the WUS format of the current cycle, and the next cycle needs to be indicated by the beacon of the next cycle. The information in the second information field of the beacon signal can also indicate whether the indication information of the beacon signal (or the format parameters indicating the wake-up signal) is effective and/or the effective duration. For example, bit 0 indicates that the indication information of the beacon signal in the current cycle is not effective, and the WUS format remains unchanged and is still the previous cycle. Bit 1 indicates that the indication information of the beacon signal in the current cycle is effective, and the WUS format is determined according to the indication information. Alternatively, in the second information field of the beacon signal, the effective duration of the indication information is directly carried by the bit information, such as two cycles.

Optionally, in this embodiment, the signal parameter includes at least one of the following:

Number of bits; coded information; sequence information.

That is, the indication information indicates the signal parameters of the control information carried in the wake-up signal, including at least one of the number of bits, coding information, and sequence information. The signal parameters include coding information, which is applicable to the case where the indication information is transmitted in a coded manner; the signal parameters include sequence information, which is applicable to the case where the indication information is transmitted in a bit sequence manner.

Optionally, the encoding information includes at least one of the following:

Coding method; coding rate; whether to perform repeated encoding; cyclic redundancy check code (CRC) length; CRC polynomial.

Here, the CRC can be scrambled using a predefined or configured scrambling sequence, such as <0,0,…0>, <0,0,…,1>. Therefore, different scrambling sequences can indicate control information of different formats. Alternatively, different CRC generating polynomials are used to distinguish control information of different formats. For example, the CRC generating polynomial for control information of format 1 is x15+x11+x10+x7+x4+x2+x+1; the CRC generating polynomial for control information of format 2 is x15+x13+x9+x8+x6+x3+x+1; at this time, the lengths of these two CRCs are both 16 bits. Different formats can also correspond to CRCs of different lengths, for example: the generating polynomial of the CRC for control information of format 1 is x15+x11+x10+x7+x4+x2+x+1; the generating polynomial of the CRC ... The formula is x15+x11+x10+x7+x4+x2+x+1; the CRC generating polynomial for the control information of format 2 is x7+x6+x3+x+1; the former is a CRC with a length of 16 bits and the latter is a CRC with a length of 8 bits.

In this embodiment, in order to enable the terminal to use a low-power receiver to receive the wake-up signal, the wake-up signal generally has the following characteristics, such as using binary on-off keying (OOK), amplitude shift keying (ASK) or frequency shift keying (FSK) to modulate the signal, or further using Manchester, pulse interval encoding (PIE), FM0, Miller, Walsh encoding and other simple encoding methods to form a combination of signal amplitudes. That is, the information is transmitted by using amplitude information or a combination of amplitude information, and the terminal only needs to demodulate the control information by judging the amplitude information or the combination of amplitude information.
