Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, without limiting the number of objects; for example, the first object can be one or more. Furthermore, "or" in this application indicates at least one of the connected objects.

The character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0034] The term "instruction" in this application can be either a direct instruction (or explicit instruction) or an indirect instruction (or implicit instruction). A direct instruction can be understood as one in which the sender explicitly informs the receiver of specific information, the operation to be performed, or the requested result, etc., in the instruction sent.

[0035] It is worth noting that the technologies described in this application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA), or other systems. The terms "system" and "network" in this application are often used interchangeably, and the described technologies can be used in the systems and radio technologies mentioned above, as well as in other systems and radio technologies. The following description describes a New Radio (NR) system for illustrative purposes, and the term NR is used in most of the following description; however, these technologies can also be applied to systems other than NR systems, such as 6th generation (6G) radio systems. thGeneration 6G communication system.

[0036] To facilitate understanding of the embodiments of this application, the following technical points are introduced first:

[0037] 1. 802.11ba Wake-Up Receiver (WUR) beacon.

[0038] The 802.11ba standard designs a low-power wake-up receiver, such as... Figure 1 As shown, an 802.11 user consists of two parts: the main interface and the wake-up receiver. The main interface is used for wireless data transmission and reception, while the wake-up receiver is used to wake up the main interface. Before being woken up, the main interface is in a closed state and does not transmit or receive data. The wake-up receiver receives the wake-up signal sent by the 802.11 wireless access point (AP). The wake-up signal can be an On-Off Keying (OOK) modulated signal, allowing the wake-up receiver to detect the wake-up signal using envelope detection, which can reduce power consumption to the level of a few hundred microwatts, greatly reducing the power consumption of the 802.11 user.

[0039] To maintain synchronization between the low-power wake-up receiver and the access point (AP), 802.11ba uses periodic transmission of WUR beacon signals to convey time information, such as... Figure 2 As shown, the type-dependent control of the WUR beacon Medium Access Control (MAC) frame carries 12 bits of information from the [5:16] section of the 64-bit Timing Synchronization Function (TSF) timer of the AP. After receiving this 12-bit information, the user updates its local TSF timer according to the time update criteria defined in 802.11ba, thereby achieving synchronization with the AP. The transmission period and the offset of the transmission start position of the WUR beacon 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 transmitted delayed in the current period, but will still be transmitted in subsequent periods according to the position determined by the WUR beacon's transmission period and transmission start position.

[0040] 2. Regarding LP-WUS in New Radio (NR).

[0041] In related technologies, research has focused on introducing LP WUR / WUS into mobile cellular systems. LP-WUS is a low-power wake-up signal, received by a low-power receiver (LP WUR) and used to wake up the main communication module, etc. For example... Figure 3 As shown, the terminal includes two modules. The first module is the main communication module, used for sending and receiving mobile communication data. The second module is a low-power wake-up receiving module, used for receiving low-power wake-up signals and low-power beacon signals sent by the transmitting end. The low-power wake-up signal is used to wake up the receiving end's main communication module, and the low-power beacon signal provides time reference information and other information for receiving the low-power wake-up signal, and can also provide wake-up link management. Figure 3 As shown, the first module remains in a closed state when not woken up by the second module, and does not send or receive data. When downlink data arrives, the second module detects a wake-up signal sent by the transmitter, and this wake-up signal contains information about the terminal. The second module then triggers the first module to switch from a closed state to a working state, enabling data reception and transmission. The second module can be continuously or intermittently powered on. When powered on, the second module can receive low-power wake-up signals and low-power beacon signals.

[0042] 3. Regarding LP-WUS

[0043] The basic format of LP-WUS is shown in Table 1.

[0044]

[0045] Table 1

[0046] The preamble field has uses including, but not limited to, at least one of the following: LP-WUS detection, synchronization, and data rate determination. Furthermore, the preamble field can also be used to indicate user identifiers or user group identifiers, etc.

[0047] Data field indicates: the part that carries the data.

[0048] 4. Regarding low-power receivers

[0049] A low-power receiver, also known as a low-power wake-up receiver (LP-WUR) or an almost zero-power wake-up receiver (AZP-WUR), operates on the principle that the receiver comprises a first module and a second module, such as... Figure 4As shown, the first module is the main communication module, used for sending and receiving mobile communication data. The second module is a low-power receiver module (also called a low-power wake-up receiver module), used to receive the wake-up signal. In power-saving mode, the terminal activates the low-power receiver module to monitor LP-WUS and disables the main communication module. When downlink data arrives, the network sends a wake-up signal to the terminal. After detecting the wake-up signal through the low-power receiver module, the terminal triggers the main communication module to turn on after a series of checks, while the low-power receiver module transitions from the active state to the off state. The low-power wake-up receiver module can be continuously or intermittently activated, and when activated, it can receive low-power wake-up signals.

[0050] 5. Regarding low-power wake-up signals

[0051] To reduce receiving activity in standby mode and effectively shut down the radio frequency (RF) and modem modules, thereby significantly reducing power consumption during communication reception, this can be achieved by introducing a near-zero power receiver into the terminal's receiver module. This near-zero power receiver eliminates the need for complex RF module signal detection (such as amplification, filtering, quantization, etc.) and modem signal processing, relying solely on passive matched filtering and low-power signal processing.

[0052] On the base station side, by triggering a wake-up signal on demand, the receiver with near-zero power can be activated to receive the activation notification, thereby triggering a series of processes within the terminal, such as turning on the radio frequency transceiver and baseband processing modules.

[0053] These wake-up signals are typically simple on-off keying (OOK) signals, such as... Figure 5 As shown, the receiver can then obtain the wake-up notification through simple energy detection and subsequent possible sequence detection and identification processes.

[0054] Since existing NR systems commonly employ Orthogonal Frequency Division Multiplexing (OFDM) signal modulation, OOK signals can be generated using OFDM signal generation methods. For example, transmitting or not transmitting an OFDM-modulated sequence represents ON / OFF in the time domain. OOK signals can be received using low-power receivers, but these receivers have poor reception performance and coverage.

[0055] Furthermore, the OFDM modulation sequence in the ON modulation can carry information through different sequences, for example, two sequences representing 0 and 1 information respectively, or four sequences representing 00, 01, 10, and 11 information respectively, such as... Figure 6 As shown, some information is modulated by OOK, and the other part is carried by an ON-level OFDM sequence.

[0056] Since demodulating OFDM sequences requires a receiver capable of receiving OFDM signals, such receivers generally have better demodulation performance than low-power receivers that can only demodulate OOK signals.
