[0004] Network energy saving is an important consideration in network design and deployment, helping to reduce costs and improve operational efficiency. Currently, network energy saving technologies mainly involve shutting down downlink transmission signals, such as the Synchronization Signal Block-less Cell (SSB-less Cell) and Discontinuous Transmission (DTX) in Release 18, activation of the Synchronization Signal Block (SSB) in neighboring cells, and paging enhancement, as well as the on-demand Synchronization Signal Block Secondary Cell (on-demand SSB Scell) and on-demand System Information Block Type 1 (on-demand SIB1) mechanisms in Release 19.

[0099] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0100] To further understand the technical content of the embodiments of this disclosure, the relevant technical content involved in this disclosure will first be introduced:

[0101] Referring to Figure 1, to further reduce the communication power consumption of terminals, the 3rd Generation Partnership Project Release 19 (3GPP R19) initiated research on Low-Power Wake-Up Receiver (LP-WUR) and Low-Power Wake-Up Signal (LP-WUS) to address the need for further reduction in terminal communication power consumption. Specifically, the terminal will have two different receivers:

[0102] Main Receiver (MR): This receiver is used to receive signals specified in the existing 3GPP New Radio (NR) technology. Specifically, this receiver has strong receiving performance and can achieve high transmission rates; however, it is also more complex and consumes more power.

[0103] Low-Power Receiver (LR): This receiver is used to receive low-power signals. In the current 3GPP R19 discussions, possible low-power signals include LP-WUS and Low-Power Synchronization Signal (LP-SS). Specifically, this receiver has relatively weak receiving performance and a limited achievable transmission rate; however, its implementation is simple and low-complexity, resulting in significantly lower power consumption than the main receiver.

[0104] Regarding random access:

[0105] After the cell search process and system information acquisition, the User Equipment (UE) has achieved downlink synchronization with the cell, at which point the UE can receive downlink data. However, the UE can only perform uplink transmission after achieving uplink synchronization with the cell. The UE establishes a connection with the cell and achieves uplink synchronization through a Random Access Procedure (RRC). After a successful RRC, the UE is in a Radio Resource Control (RRC) connected state and can perform normal uplink and downlink transmissions with the network.

[0106] The main purposes of random access are: (1) to obtain uplink synchronization; (2) to assign a unique Cell-Radio Network Temporary Identifier (C-RNTI) to the UE.

[0107] There are two different methods for the random access process:

[0108] 1. Contention-based random access (CBRA), as shown in Figure 2. In CBRA, the UE randomly selects a preamble from a contention-based preamble pool shared with other UEs in the cell and transmits it on the Physical Random Access Channel (PRACH). The cell then sends a Random Access Response (RAR) to indicate the received preamble and provides uplink timing advance to adjust the UE's uplink transmission timing. If multiple UEs simultaneously select the same PRACH resource and transmit the same preamble (Msg1), these UEs will decode the same RAR (Msg2) and transmit Physical Uplink Shared Channel (PUSCH) data (Msg3) on the same uplink time-frequency resource, resulting in a collision. In Msg4, the network resolves the collision and sends the winning UE's information to the UE.

[0109] 2. Contention-free random access (CFRA), as shown in Figure 3. In CFRA, the network provides the UE with a dedicated preamble via RRC signaling or Physical Downlink Control Channel (PDCCH) orders, thus eliminating conflicts.

[0110] This disclosure provides a communication method executed by a terminal. Referring to Figure 4, which is a flowchart of the communication method provided in this disclosure, the method includes the following steps:

[0111] Step 401: Send a first uplink signal to the network device, the first uplink signal being used to wake up the network device;

[0112] In this step, referring to Figures 5 and 6, before the terminal initiates a four-step random access procedure (i.e., a contention-based random access procedure) or a two-step random access procedure (i.e., a non-contention-based random access procedure) to the network device, the terminal can first send a low-power wake-up signal (Msg0), which is the first uplink signal mentioned above. Furthermore, the network device typically sends a high-power synchronization signal to the terminal. If the network device does not send a high-power synchronization signal to the terminal, the aforementioned first uplink signal can also be used to wake up the network device to send the high-power synchronization signal.

[0113] Network equipment can be understood as equipment such as base stations.

[0114] Optionally, the terminal sends the first uplink signal to the network device under at least one of the following conditions:

[0115] The terminal needs to undergo a state transition;

[0116] The terminal needs to access the network;

[0117] The terminal needs to perform uplink synchronization.

[0118] The terminal needs to perform state transitions, for example: from a disconnected state to a connected state, where the disconnected state includes an idle state and an inactive state; from a power-saving state to a working state; and from a hibernation state to a non-hibernation state.

[0119] The terminal needs to access the network; for example, the terminal needs to register with the network.

[0120] This uplink low-power signal may differ from the signal used in normal communication between the terminal and the network. The differences may include:

[0121] (1) The modulation and / or coding methods are different, for example, the existing on-off keying (OOK) signal is compared with the signal in the existing NR;

[0122] (2) The uplink low power signal is a simplification of the signal used in normal communication, such as the LP-WUS signal based on orthogonal frequency division multiplexing (OFDM) in LP-WUS.

[0123] Therefore, network devices can have an independent low-power receiver to receive the uplink low-power signal, or they can use a normal communication receiver to receive the signal. If a normal communication receiver is used, the base station may disable some components or functions of the receiver before using it to receive the uplink low-power signal.

[0124] Step 402: If it is determined that the network device is woken up, send a second uplink signal to the network device, wherein the power of the first uplink signal is less than the power of the second uplink signal.

[0125] In this step, after determining that the network device has been woken up, the terminal sends a second uplink signal to the network device. This second uplink signal can be understood as an uplink high-power signal.

[0126] In one implementation, the network device is woken up based on a first uplink signal received from the terminal, and then receives a second uplink signal from the terminal. The power consumption of the first uplink signal is less than that of the second uplink signal. This avoids the network device continuously receiving high-power uplink signals from the terminal, thereby reducing the uplink receiving power consumption of the network device and further achieving network energy saving.

[0127] Optionally, before sending the first uplink signal to the network device, the method further includes:

[0128] Receive configuration information sent by the network device, the configuration information including time-frequency domain resources corresponding to the first uplink signal;

[0129] Sending the first uplink signal to the network device includes:

[0130] The first uplink signal is sent to the network device from the time-frequency domain resources.

[0131] In one implementation, before the terminal sends the first uplink signal to the network device, the network device broadcasts some configuration information to the terminal to enable better interaction between the terminal and the network device. If the terminal is accessing the network device for the first time, it obtains the configuration information by reading the network system messages broadcast by the network device; if the terminal is not accessing the network device for the first time, it obtains the configuration information by reading the RRC dedicated signaling broadcast by the network device.

[0132] The configuration information may include time-frequency domain resources corresponding to the first uplink signal, and may also include the transmit power corresponding to the first uplink signal, and the sequence or generation sequence information used by the first uplink signal, so that the terminal can send the first uplink signal to the network device according to the configuration information.

[0133] This implementation method, by explicitly specifying time-frequency domain resources, enables the network to optimize scheduling to reduce interference and resource conflicts, improve spectrum efficiency, and reduce the risk of packet loss by ensuring that uplink signals are sent on specific time-frequency domain resources, thereby improving communication reliability and connection robustness.

[0134] Optionally, the configuration information may further include at least one of the following:

[0135] Wake-up condition information is used by the terminal to determine whether the network device has been woken up.

[0136] Feedback configuration information is used by the terminal to determine whether the network device has been woken up, based on the feedback signal sent by the network device to the first uplink signal.

[0137] In one implementation, the configuration information further includes wake-up condition information, which the terminal can use to determine whether the network device has been woken up. For example, the wake-up condition message may include a waiting window length for the terminal; if the terminal receives a feedback signal from the network device within the waiting window length, it can consider the network device to have been woken up. The configuration information may also include feedback configuration information. Further, the terminal can combine the feedback configuration information and the feedback signal to determine whether the network device has been woken up. For example, in addition to receiving the feedback signal from the network device within the waiting window length, the terminal must also confirm that the feedback signal includes a network device activation indication to confirm that the network device has been woken up.

[0138] In addition to being configured by network devices, the above information can also be specified through protocols.

[0139] In this implementation, the information terminal can determine whether the network device needs to be woken up, thereby avoiding unnecessary energy consumption. If the network device remains awake when not needed, it will waste battery life.

[0140] Optionally, after sending the first uplink signal to the network device and before sending the second uplink signal to the network device, the method further includes:

[0141] Receive feedback signals sent by the network device;

[0142] Based on the wake-up condition information and / or the feedback configuration information, it is determined whether the network device is woken up;

[0143] The wake-up condition information includes determining that the network device is woken up if the feedback signal is received;

[0144] If the feedback signal includes an activation indication of the network device, it is determined that the network device has been woken up.

[0145] Optionally, if the wake-up condition information includes a waiting window length, and the time between receiving the feedback signal and sending the first uplink signal is within the waiting window length, then it is determined that the network device has been woken up.

[0146] In one implementation, after the terminal sends a first uplink signal to the network device, it can receive a feedback signal sent by the network device based on the first uplink signal. Then, the terminal determines whether the network device has been woken up based on the feedback signal, according to wake-up condition information and / or feedback configuration information.

[0147] In one scenario, the terminal considers the network device to be awakened upon receiving a feedback signal from the network device. In another scenario, the terminal needs to receive a feedback signal from the network device within the waiting window configured for the network device to be considered awakened, and this feedback signal does not need to include any specific indication information. In yet another scenario, in addition to receiving a feedback signal from the network device within the waiting window, the terminal also needs to confirm that the feedback signal includes an activation indication for the network device in order to determine that the network device has been awakened. If the feedback signal includes an indication for the network device to continue sleeping or power saving, it means that the network device has not been awakened.

[0148] In this implementation, by defining the waiting window length and the timing relationship of the feedback signal, the terminal can more accurately determine the wake-up status of the network device. This accuracy helps reduce false alarms and ensures the effective utilization of network resources. By utilizing the activation indication in the feedback signal, the terminal can further confirm the device's status, enhancing system reliability and reducing communication failures caused by unclear device status.

[0149] Optionally, after sending the first uplink signal to the network device and before receiving the feedback signal sent by the network device, the method further includes:

[0150] If no feedback signal is received from the network device within the waiting window, the first uplink signal is repeatedly sent to the network device until the number of repeated transmissions reaches a preset maximum number of transmissions, or until a feedback signal from the network device is received before the maximum number of transmissions is reached.

[0151] In one implementation, if the terminal does not receive a feedback signal from the network device within the waiting time window, the terminal may repeatedly send the first uplink signal to the network device based on the network device's configuration information or protocol specifications until the number of repeated transmissions reaches the preset maximum number of transmissions or until a feedback signal from the network device is received before that.

[0152] In this implementation, even if channel conditions are poor, the mechanism of repeated transmission can compensate for temporary signal quality degradation and improve system robustness.

[0153] Optionally, the method further includes:

[0154] The feedback signal may include a sleep indicator or power saving indicator for the network device, or, if the number of repeated transmissions reaches the maximum number of transmissions and no feedback signal is received from the network device, a cell reselection procedure may be initiated for the network device.

[0155] In one implementation, if the terminal receives a feedback signal from the network device that includes a sleep indicator or power-saving indicator from the network device, the terminal can assume that it cannot access the cell and can initiate cell reselection. This can reduce unnecessary waiting time and improve the speed of accessing other available cells. Alternatively, if the terminal does not receive a feedback signal from the network device within the waiting time window, and then repeatedly sends the first uplink signal to the network device until the number of repeated transmissions reaches a preset maximum number of transmissions and still does not receive a feedback signal from the network device, the terminal can assume that it cannot access the cell and can initiate cell reselection. This can reduce unnecessary repeated requests and invalid uplink signal transmissions, thereby reducing the signaling burden of the target cell and optimizing overall network performance.

[0156] Optionally, the terminal does not send a signal to the network device within a preset waiting time after sending the first uplink signal, and determines that the network device has been woken up after the preset waiting time.

[0157] In one implementation, after sending the first uplink signal, the terminal may refrain from sending any messages to the network device for a preset waiting time configured by the network device or a preset waiting time specified in the protocol. After the preset waiting time, the terminal assumes the network device has been awakened and can send a second uplink signal. This implementation avoids unnecessary data transmission by refraining from sending other messages within the preset waiting time, thereby reducing network interference and conflicts. Furthermore, it takes into account the time required for the network device to transition from a dormant state to an active state, making communication between the terminal and the network more efficient and stable.

[0158] Optionally, the configuration information may also include a maximum random access threshold;

[0159] After determining that the network device has been woken up, the method further includes any one of the following:

[0160] If the terminal initiates random access using the second uplink signal to the network device once the preset maximum number of times has been reached, the terminal may send the first uplink signal again, or receive a random access response (RAR) and determine the network status, or determine that the random access has failed, or retreat to step four to reach the RACH.

[0161] If the maximum number of random access attempts is less than the preset maximum number of attempts and the number of random access attempts initiated by the terminal reaches the maximum number of random access attempts, the first uplink signal is sent to the network device again. If the number of random access attempts initiated by the terminal reaches the preset maximum number of attempts, the random access is determined to have failed, or the process is reversed to the four-step RACH.

[0162] If the maximum number of random access attempts is greater than the preset maximum number of attempts and the number of random access attempts initiated by the terminal reaches the preset maximum number of attempts, the first uplink signal is sent to the network device again. If the number of random access attempts initiated by the terminal reaches the maximum number of random access attempts, the random access is determined to have failed, or the process is reversed to the four-step RACH.

[0163] In one implementation, after sending the first uplink signal, the terminal may not send any messages to the network device for a preset waiting time configured by the network device or a preset waiting time specified in the protocol, and assume that the network device has been woken up after the preset waiting time. However, in this case, the network device does not explicitly send any message indicating that it has been woken up, and the terminal may misjudge. Therefore, verification can be performed through multiple random access and multiple wake-up processes. Verification can be performed using any of the following methods:

[0164] 1. When the terminal initiates random access using the second uplink signal and reaches the preset maximum number of times, it can decide whether to send the first uplink signal to the network device again based on the network configuration or protocol, or receive RAR and determine the network status, or determine that the random access has failed and indicate to the upper layer when the random access is a four-step random access, or back to a four-step RACH when the random access is a two-step random access.

[0165] 2. The network device can be configured with an additional maximum random access attempt threshold. When the maximum random access attempt threshold is less than the preset maximum and the terminal initiates random access attempts to the maximum random access attempt threshold, the device can decide whether to resend the first uplink signal to the network device based on network configuration or protocol specifications. It is possible that the random access attempt count will not be cleared to zero; that is, if the terminal re-initiates random access after repeatedly sending the first uplink signal, it is considered the same RACH procedure. If the terminal initiates random access attempts to the preset maximum, and the random access is a four-step random access, the random access is deemed a failure and an indication is sent to the upper layer; or if the random access is a two-step random access, it reverts to a four-step RACH.

[0166] 3. The network device can be configured with an additional maximum random access attempt threshold. When the maximum random access attempt threshold exceeds a preset maximum and the terminal initiates random access attempts to the maximum, the device can decide whether to resend the first uplink signal to the network device based on network configuration or protocol specifications. It is possible that the random access attempt count will not be cleared to zero; that is, if the terminal re-initiates random access after repeatedly sending the first uplink signal, it is considered the same RACH procedure. When the terminal's random access attempt count reaches the maximum random access attempt threshold, if the random access is a four-step random access, it is determined to have failed and an indication is sent to the upper layer; or if the random access is a two-step random access, it reverts to a four-step RACH.

[0167] The above implementation method, through multi-step strategies and condition judgments, enables the terminal to have more opportunities to attempt a successful connection even in situations with weak signals or network congestion.

[0168] Optionally, the first uplink signal is further used to initiate a random access request to the network device, and the first uplink signal carries a preamble.

[0169] In one implementation, referring to Figures 7 and 8, the first uplink signal can be used not only to wake up the network device but also to initiate a four-step random access procedure or a two-step random access procedure to the network device. In this case, the first uplink signal serves as both a wake-up signal and a random access trigger signal. Compared to waking up the network device using the first uplink signal and then initiating a random access request to the network device using the second uplink signal, this implementation can reduce the latency of the terminal's random access.

[0170] Optionally, the configuration information further includes first indication information, used to indicate that a random access procedure is triggered by the first uplink signal, wherein the first uplink signal carries a preamble.

[0171] In one implementation, the process of triggering random access using a first uplink signal may be instructed by a network device. This method, where the network device instructs the terminal to trigger the random access process, ensures that the process is performed on demand, avoiding resource waste caused by unnecessary random access attempts.

[0172] Optionally, the configuration information may further include at least one of the following:

[0173] The period of the first uplink signal;

[0174] The beam correlation between the first uplink signal and the second uplink signal;

[0175] The time interval between receiving the first uplink signal and sending a feedback signal by the network device.

[0176] In one implementation, the network device, by specifying a periodic transmission mechanism for the first uplink signal, can help the terminal device better manage power consumption, thereby extending the terminal device's battery life. By indicating the beam association relationship between the first and second uplink signals, the network device enables the terminal to select the optimal transmission mode under different conditions, improving signal quality and data transmission efficiency. By indicating the interval between receiving the first uplink signal and sending the feedback signal, the network device allows the terminal to reasonably estimate the waiting time and optimize subsequent operations and response strategies. Furthermore, the network device can indicate whether the feedback signal sent to the terminal is a low-power signal or a high-power signal, enabling the terminal to determine which receiver to use to receive the feedback signal sent by the network device.

[0177] This disclosure provides a communication method executed by a network device. Referring to Figure 9, which is a flowchart of the communication method provided in this disclosure, the method includes the following steps:

[0178] Step 901: Receive the first uplink signal sent by the receiving terminal;

[0179] Step 902: When awakened by the first uplink signal, receive the second uplink signal sent by the terminal, wherein the power consumption of the first uplink signal is less than the power consumption of the second uplink signal.

[0180] Optionally, before receiving the first uplink signal sent by the terminal, the method further includes:

[0182] The first uplink signal sent by the receiving terminal includes:

[0183] The receiving terminal transmits the first uplink signal in the time-frequency domain resource.

[0184] Optionally, the configuration information may further include at least one of the following:

[0185] Wake-up condition information is used by the terminal to determine whether the network device has been woken up.

[0186] Feedback configuration information is used by the terminal to determine whether the network device has been woken up, based on the feedback signal sent by the network device to the first uplink signal.

[0187] Optionally, after the receiving terminal sends the first uplink signal, the method further includes:

[0188] Send a feedback signal to the terminal.

[0189] It should be noted that this embodiment is an implementation of the network device corresponding to the embodiment shown in Figure 4. For specific implementation details, please refer to the relevant description of the embodiment shown in Figure 4. In order to avoid repeated descriptions, this embodiment will not be repeated, and the same beneficial effects can be achieved.

[0190] Optionally, receiving the second uplink signal sent by the terminal includes:

[0191] The location of the terminal in the beam is determined based on the first uplink signal;

[0192] When the preset energy saving amount of the network device is greater than the first preset value and / or the number of components activated by the network device is less than the second preset value, the second uplink signal sent by the terminal is received at the beam position where the terminal is located.

[0193] When the preset energy saving amount of the network device is less than the first preset value and / or the number of components activated by the network device is greater than the second preset value, the second uplink signal sent by the terminal is received at all beam positions.

[0194] In one implementation, the network device can determine which beam the terminal is on based on the received first uplink signal. The network device can then choose to receive the terminal's second uplink signal only on that beam, or on that beam and its adjacent beams, or on all beams, depending on the network device's energy-saving requirements and / or the on / off status of its components. If the network device's preset energy-saving threshold is greater than a first preset value and / or the number of activated components is less than a second preset value, the network device can choose to receive the terminal's second uplink signal at the beam where the terminal is located. If the network device's preset energy-saving threshold is less than the first preset value and / or the number of activated components is greater than the second preset value, the network device can choose to receive the terminal's second uplink signal at all beam locations.

[0195] In this implementation, an intelligent beam selection strategy enables network devices to effectively balance performance, energy consumption, and resource management, thereby improving the overall quality of service.

[0196] Optionally, the configuration information further includes first indication information, used to indicate that a random access procedure is triggered by the first uplink signal, wherein the first uplink signal carries a preamble.

[0197] Optionally, the configuration information may also include at least one of the following:

[0198] The period of the first uplink signal;

[0199] The beam correlation between the first uplink signal and the second uplink signal;

[0200] The time interval between receiving the first uplink signal and sending a feedback signal by the network device.

[0201] It should be noted that this embodiment is an implementation of the network device corresponding to the embodiment shown in Figure 4. For specific implementation details, please refer to the relevant description of the embodiment shown in Figure 4. In order to avoid repeated descriptions, this embodiment will not be repeated, and the same beneficial effects can be achieved.

[0202] Optionally, after receiving the second uplink signal sent by the terminal when awakened by the first uplink signal, the method further includes:

[0203] If it is determined that the terminal is not transmitting signals with the network device, it enters a sleep state.

[0204] In one implementation, when the network device determines that it does not need to send downlink signals to the terminal or receive uplink signals from the terminal, it enters a sleep state, and this can be indicated by configuration information sent by the network device to the terminal. This implementation can save power consumption of the network device.

[0205] Optionally, after the receiving terminal sends the first uplink signal and before receiving the second uplink signal sent by the terminal, the method further includes:

[0206] Turn on the main receiver, or switch the receiver's operating module from the first operating state to the second operating state, wherein the power consumption of the first operating state is less than the power consumption of the second operating state.

[0207] In one implementation, after the network device is woken up by receiving the first uplink signal (low-power signal) sent by the terminal, it needs to prepare to receive the second uplink signal (high-power signal) sent by the terminal. At this time, the terminal can turn on the main receiver (i.e., the non-low-power receiver used for normal communication) or switch the working module in the normal receiver that was previously in the low-power working state to the high-power working state.

[0208] This implementation method can optimize the allocation of network and device resources and improve the efficiency of the entire system by adjusting the power consumption of the receiver according to actual communication needs.
