[0002] Network energy saving is an important consideration in network design and deployment, which helps to reduce costs and improve operational efficiency.

[0097] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0098] In order to further understand the technical content of each embodiment of the present application, the related content of the prior art involved in the present application is first introduced:

[0099] See also Figure 1 In order to further reduce the communication power consumption of the terminal, the 19th edition of the technical specification (3rd Generation Partnership Project Release 19, 3GPP R19) formulated by the 3rd Generation Partnership Project launched the research on low-power wake-up receiver (Low-Power Wake-Up Receiver, LP-WUR) and low-power wake-up signal (Low-Power Wake-Up Signal, LP-WUS). Specifically, the terminal will have two different receivers:

[0100] Main Receiver (MR): This receiver is used to receive signals specified in the existing 3GPP New Radio (NR) technology. Specifically, the receiver has strong receiving performance and can achieve a high transmission rate; but at the same time, its receiver complexity is high and the power consumption is high.

[0101] Low-Power Receiver (LR): This receiver is used to receive low-power signals. In the current 3GPP R19 discussion, possible low-power signals include LP-WUS and Low-Power Synchronization Signal (LP-SS). Specifically, the reception performance of this receiver is relatively weak, and the achievable transmission rate is limited; but at the same time, its receiver implementation is simple and low in complexity, so the power consumption is much lower than that of the main receiver.

[0102] About random access:

[0103] After the cell search process and obtaining system information, the user equipment (UE) has achieved downlink synchronization with the cell, and the UE can now 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 the random access procedure. After the random access procedure is successful, the UE is in the Radio Resource Control (RRC) connected state and can perform normal uplink and downlink transmission with the network.

[0104] The main purposes of random access are: (1) to obtain uplink synchronization; (2) to allocate a unique Cell-Radio Network Temporary Identifier (C-RNTI) to the UE.

[0105] There are two different ways of random access process:

[0106] 1. Contention-based random access (CBRA), such as Figure 2As shown. In CBRA, the UE randomly selects a preamble from the 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 provide an uplink timing advance to adjust the UE's uplink transmission time (timing). If multiple UEs simultaneously select the same PRACH resource to send the same preamble (i.e., Msg1), these UEs will decode the same RAR (i.e., Msg2) and send physical uplink shared channel (PUSCH) data (i.e., Msg3) on the same uplink time-frequency resources, resulting in a conflict. In Msg4, the network resolves the conflict and sends the winning UE's information to the UE.

[0107] 2. Non-contention-free random access (CFRA), such as Figure 3 In CFRA, the network provides a dedicated preamble to the UE through RRC signaling or Physical Downlink Control Channel (PDCCH) order, so there is no conflict.

[0108] The present application embodiment provides a communication method, which is executed by a terminal. Figure 4 , Figure 4 is a flow chart of a communication method provided in an embodiment of the present application, such as Figure 4 As shown, the following steps are included:

[0109] Step 401: Send a first uplink signal to a network device, where the first uplink signal is used to wake up the network device;

[0110] In this step, see Figure 5 and Figure 6 Before the terminal initiates a four-step random access process (i.e., a contention-based random access process) or a two-step random access process (i.e., a non-contention-based random access process) to the network device, the terminal may first send a low-power wake-up signal (Msg0) to the network device, i.e., the first uplink signal mentioned above. In addition, the network device generally 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 may also be used to wake up the network device to send a high-power synchronization signal.

[0111] Network equipment can be understood as equipment such as base stations.

[0112] Optionally, the terminal sends the first uplink signal to the network device when at least one of the following conditions is met:

[0113] The terminal needs to perform state transition;

[0114] The terminal needs to access the network;

[0115] The terminal needs to perform uplink synchronization.

[0116] The terminal needs to perform state transitions, illustratively: from a non-connected state to a connected state, where the non-connected state includes an idle state and an inactive state; from a power-saving state to a working state; and from a sleep state to a non-sleep state.

[0117] The terminal needs to access the network. For example, the terminal needs to register with the network.

[0118] The uplink low power consumption signal may be different from the signal used for normal communication between the terminal and the network. The difference may include:

[0119] (1) The modulation and / or coding methods are different, such as the existing On-Off Keying (OOK) signal compared to the signal in the existing NR;

[0120] (2) The uplink low power consumption signal is a simplification of the signal used for normal communication, such as the LP-WUS signal based on Orthogonal Frequency Division Multiplexing (OFDM) in LP-WUS.

[0121] Therefore, the network device can have an independent low-power receiver to receive the uplink low-power signal, or use a normal communication receiver to receive the signal. If a normal communication receiver is used, the base station may turn off some components or functions of the receiver before using it to receive the uplink low-power signal.

[0122] Step 402: When it is determined that the network device is awakened, 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.

[0123] In this step, after determining that the network device is awakened, the terminal sends a second uplink signal to the network device. The second uplink signal can be understood as an uplink high power consumption signal.

[0124] In one implementation, after the network device is awakened based on the first uplink signal received from the terminal, it receives the second uplink signal from the terminal, and the power consumption of the first uplink signal is less than that of the second uplink signal. This can prevent the network device from constantly receiving the uplink high-power consumption signal from the terminal, thereby further achieving the purpose of network energy saving by reducing the uplink receiving power consumption of the network device.

[0125] Optionally, before sending the first uplink signal to the network device, the method further includes:

[0126] receiving configuration information sent by the network device, where the configuration information includes time-frequency domain resources corresponding to the first uplink signal;

[0127] The sending a first uplink signal to the network device includes:

[0128] The first uplink signal is sent to the network device in the time-frequency domain resources.

[0129] 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 so that the terminal and the network device can interact better. If the terminal accesses the network device for the first time, the configuration information is obtained by reading the network system message broadcast by the network device; if the terminal is not accessing the network device for the first time, the configuration information is obtained by reading the RRC dedicated signaling broadcast by the network device.

[0130] The configuration information will include the time-frequency domain resources corresponding to the first uplink signal, and may also include the transmission power corresponding to the first uplink signal, the sequence used by the first uplink signal or the generated sequence information, so that the terminal sends the first uplink signal to the network device according to the configuration information.

[0131] By explicitly specifying time-frequency domain resources, this implementation method enables the network to optimize scheduling to reduce interference and resource conflicts and improve spectrum efficiency. By ensuring that uplink signals are sent on specific time-frequency domain resources, the risk of packet loss can be reduced and the reliability of communication and the robustness of the connection can be improved.

[0132] Optionally, the configuration information also includes at least one of the following:

[0133] Wake-up condition information, used by the terminal to determine whether the network device is awakened;

[0134] Feedback configuration information is used by the terminal to determine whether the network device is awakened in combination with a feedback signal sent by the network device in response to the first uplink signal.

[0135] In one implementation, the configuration information also includes wake-up condition information, and the terminal can determine whether the network device is awakened based on the wake-up condition information. Exemplarily, the wake-up condition message can include the waiting window length of the terminal, and the terminal can consider that the network device is awakened when it receives a feedback signal sent by the network device within the waiting window length. The configuration information can also include feedback configuration information. Further, the terminal can determine whether the network device is awakened in combination with the feedback configuration information and the feedback signal. Exemplarily, in addition to receiving the feedback signal sent by the network device within the waiting window length, the terminal must also confirm that the feedback signal includes a network device activation indication before confirming that the network device is awakened.

[0136] In addition to being configured by network devices, the above information can also be specified through protocols.

[0137] In this implementation, the information terminal can be used to determine whether the network device needs to be awakened, thereby avoiding unnecessary energy consumption. If the network device remains awake when it is not needed, battery life will be wasted.

[0138] 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:

[0139] receiving a feedback signal sent by the network device;

[0140] Determining whether the network device is awakened according to the awakening condition information and / or the feedback configuration information;

[0141] The wake-up condition information includes: if the feedback signal is received, it is determined that the network device is awakened;

[0142] In a case where the feedback signal includes an activation indication of the network device, it is determined that the network device is awakened.

[0143] Optionally, when the wake-up condition information includes a waiting window length, if a distance between a time of receiving the feedback signal and a time of sending the first uplink signal is within the waiting window length, it is determined that the network device is awakened.

[0144] In one implementation, after the terminal sends the first uplink signal to the network device, it can receive a feedback signal sent by the network device based on the first uplink signal. The terminal then determines whether the network device is awakened based on the feedback signal according to the awakening condition information and / or feedback configuration information.

[0145] In one case, the terminal regards the network device as being awakened when it receives a feedback signal sent by the network device; in another case, the terminal needs to receive a feedback signal sent by the network device within the waiting window length configured by the network device before it regards the network device as being awakened, and the feedback signal does not need to include any specific indication information; in another case, in addition to receiving the feedback signal sent by the network device within the waiting window length, the terminal also needs to confirm that the feedback signal includes an activation indication of the network device before determining that the network device is awakened. If the feedback signal includes a continued sleep or energy-saving indication of the network device, it means that the network device has not been awakened.

[0146] In this implementation, by clarifying the time relationship between the waiting window length and the feedback signal, the terminal can more accurately determine the wake-up state of the network device. This accuracy helps to reduce misjudgment and ensure the effective use of network resources. By using the activation indication in the feedback signal, the terminal can further confirm the status of the device, enhance the reliability of the system, and reduce communication failures caused by unclear device status.

[0147] 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:

[0148] When no feedback signal sent by the network device is received within the waiting window length, 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 a feedback signal sent by the network device is received before the maximum number of transmissions is reached.

[0149] In one implementation, if the terminal does not receive a feedback signal sent by the network device within the waiting time window, the terminal may repeatedly send a first uplink signal to the network device based on the configuration information or protocol provisions of the network device until the number of repeated transmissions reaches a preset maximum number of transmissions or before the terminal receives a feedback signal sent by the network device.

[0150] In this implementation, even if the channel condition is not good, the repeated transmission mechanism can compensate for the temporary signal quality degradation and improve the robustness of the system.

[0151] Optionally, the method further comprises:

[0152] The feedback signal includes a sleep indication or a power saving indication of the network device, or when the number of repeated transmissions reaches a maximum number of transmissions and the feedback signal sent by the network device is not received, a cell reselection process is initiated to the network device.

[0153] In one implementation, if the feedback signal received by the terminal from the network device includes a sleep indication or a power-saving indication of the network device, the terminal may consider that the cell cannot be accessed, and may initiate cell reselection, thereby reducing unnecessary waiting time and improving the speed of accessing other available cells; or if the terminal does not receive the feedback signal sent by 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 the feedback signal sent by the network device, the terminal may consider that the cell cannot be accessed, and may initiate cell reselection, thereby reducing unnecessary repeated requests and invalid uplink signal transmissions, thereby reducing the signaling burden of the target cell and optimizing the overall network performance.

[0154] 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 is awakened after the preset waiting time.

[0155] In one implementation, after sending the first uplink signal, the terminal may not send any message to the network device within the preset waiting time configured by the network device or the preset waiting time specified by the protocol, and after the preset waiting time, the network device is considered to have been awakened, and a second uplink signal may be sent to the network device. In this implementation, the terminal does not send other messages within the preset waiting time, which can avoid unnecessary data transmission, thereby reducing interference and conflict with the network. And taking into account the time required for the network device to switch from a dormant state to an active state, the communication between the terminal and the network is more efficient and stable.

[0156] Optionally, the configuration information also includes a maximum random access number threshold;

[0157] After determining that the network device is awakened, the method further includes any one of the following:

[0158] When the number of times the terminal initiates random access using the second uplink signal reaches a preset maximum number, the terminal sends the first uplink signal to the network device again, or receives a random access response RAR and determines the network state, or determines that the random access fails, or falls back to step four to reach RACH;

[0159] When the maximum random access number threshold is less than the preset maximum number and the number of random access initiated by the terminal reaches the maximum random access number threshold, sending the first uplink signal to the network device again, and when the number of random access initiated by the terminal reaches the preset maximum number, determining that the random access fails, or retreating to the four-step RACH;

[0160] When the maximum random access number threshold is greater than the preset maximum number and the number of random access initiated by the terminal reaches the preset maximum number, the first uplink signal is sent to the network device again, and when the number of random access initiated by the terminal reaches the maximum random access number threshold, it is determined that the random access fails, or it is retreated to the four-step RACH.

[0161] In one implementation, after sending the first uplink signal, the terminal may not send any message to the network device within the preset waiting time configured by the network device or the preset waiting time specified by the protocol, and considers that the network device has been awakened after the preset waiting time. However, in this case, the network device does not explicitly send any message indicating that it has been awakened, and the terminal may have misjudged it, so it can be verified through multiple random access and multiple wake-up processes. The verification can be carried out in any of the following ways:

[0162] 1. When the number of times the terminal initiates random access using the second uplink signal reaches a preset maximum number, it can decide whether to send the first uplink signal to the network device again based on the network configuration or protocol provisions, or receive RAR and determine the network status, or determine that the random access fails and indicate to the upper layer when the random access is a four-step random access, or fall back to the four-step RACH when the random access is a two-step random access;

[0163] 2. The network device may be configured with an additional maximum random access number threshold. When the maximum random access number threshold is less than the preset maximum number and the number of random access initiated by the terminal reaches the maximum random access number threshold, it may be determined whether to send the first uplink signal to the network device again based on the network configuration or protocol provisions, and it is possible that the number of random access transmissions is not cleared to 0, that is, the process of initiating random access again after the terminal repeatedly sends the first uplink signal is considered to be the same RACH procedure. When the number of random access initiated by the terminal reaches the preset maximum number, when the random access is a four-step random access, it is determined that the random access fails and indicates it to the upper layer, or when the random access is a two-step random access, it falls back to a four-step RACH;

[0164] 3. The network device may be configured with an additional maximum random access number threshold. When the maximum random access number threshold is greater than the preset maximum number and the number of random access initiated by the terminal reaches the preset maximum number, it may be determined whether to send the first uplink signal to the network device again based on the network configuration or protocol provisions, and it is possible that the number of random access transmissions is not cleared to 0, that is, the process of initiating random access again after the terminal repeatedly sends the first uplink signal is considered to be the same RACH Procedure. When the number of random access initiated by the terminal reaches the maximum random access number threshold, when the random access is a four-step random access, it is determined that the random access fails and indicates it to the upper layer, or when the random access is a two-step random access, it falls back to a four-step RACH.

[0165] The above implementation method uses a multi-step strategy and condition judgment to enable the terminal to have more opportunities to attempt a successful connection even in the case of weak signals or network congestion.

[0166] Optionally, the first uplink signal is also used to initiate a random access request to the network device, and the first uplink signal carries a preamble code.

[0167] In one embodiment, see Figure 7 and Figure 8 In addition to being used to wake up the network device, the first uplink signal can also be used to initiate a four-step random access process or a two-step random access process to the network device. In this case, the first uplink signal is both a wake-up signal and a random access trigger signal. Compared with using the first uplink signal to wake up the network device and then using the second uplink signal to initiate a random access request to the network device, this implementation method can shorten the delay of terminal random access.

[0168] Optionally, the configuration information further includes first indication information, used to indicate that a random access process is triggered by the first uplink signal, and the first uplink signal carries a preamble code.

[0169] In one implementation, the process of the terminal triggering random access using the first uplink signal may be instructed by a network device. In this implementation, the network device instructs the terminal to trigger the random access process, which can ensure that the process is performed on demand and avoid resource waste caused by unnecessary random access attempts.

[0170] Optionally, the configuration information also includes at least one of the following:

[0171] a period of the first uplink signal;

[0172] A beam association relationship between the first uplink signal and the second uplink signal;

[0173] The duration of the interval from when the network device receives the first uplink signal to when it sends the feedback signal.

[0174] In one implementation, the network device can help the terminal device better manage energy consumption by specifying a periodic transmission mechanism for the first uplink signal, thereby extending the battery life of the terminal device. The network device indicates the beam association relationship between the first uplink signal and the second uplink signal, so that the terminal can select the best transmission mode under different conditions to improve signal quality and data transmission efficiency. The network device indicates the interval length from receiving the first uplink signal to sending the feedback signal, so that the terminal can reasonably estimate the waiting time and optimize subsequent operations and response strategies. In addition, the network device can indicate whether the feedback signal sent by the network device to the terminal is a low-power signal or a high-power signal, so that the terminal can determine what kind of receiver to use to receive the feedback signal sent by the network device.

[0175] The present application embodiment provides a communication method, which is executed by a network device. Fig. 9 , Figure 7 is a flow chart of a communication method provided in an embodiment of the present application, such as Fig. 9 As shown, the following steps are included:

[0176] Step 901: Receive a first uplink signal sent by a terminal;

[0177] Step 902: When awakened by the first uplink signal, receive a second uplink signal sent by the terminal, wherein power consumption of the first uplink signal is less than power consumption of the second uplink signal.

[0178] Optionally, before receiving the first uplink signal sent by the terminal, the method further includes:

[0179] Sending configuration information to a terminal, where the configuration information includes time-frequency domain resources corresponding to the first uplink signal;

[0182] Optionally, the configuration information also includes at least one of the following:

[0183] Wake-up condition information, used by the terminal to determine whether the network device is awakened;

[0185] Optionally, after receiving the first uplink signal sent by the terminal, the method further includes:

[0186] A feedback signal is sent to the terminal.

[0187] It should be noted that this embodiment is Figure 4 The implementation methods of the corresponding network devices in the embodiment shown in the figure can be found in the specific implementation methods. Figure 4 In order to avoid repeated description, the relevant description of the embodiment shown will not be repeated in this embodiment, and the same beneficial effects can still be achieved.

[0188] Optionally, the receiving a second uplink signal sent by the terminal includes:

[0189] Determine the beam position of the terminal based on the first uplink signal;

[0190] When the preset energy saving amount of the network device is greater than a first preset value and / or the number of activated components of the network device is less than a second preset value, receiving a second uplink signal sent by the terminal at the beam position where the terminal is located;

[0191] When the preset energy saving amount of the network device is less than the first preset value and / or the number of activated components of the network device is greater than the second preset value, the second uplink signal sent by the terminal is received at all beam positions.

[0192] In one implementation, the network device can determine which beam the terminal is on based on the received first uplink signal, and then the network device can choose to receive the second uplink signal of the terminal only on the beam or on the beam and its adjacent beams, or receive the second uplink signal of the terminal on all beams, depending on the energy saving requirements of the network device and / or the switching conditions of the components of the network device. When the preset energy saving amount of the network device is greater than the first preset value and / or the number of activated components of the network device is less than the second preset value, the network device can choose to receive the second uplink signal sent by the terminal at the beam position where the terminal is located; when the preset energy saving amount of the network device is less than the first preset value and / or the number of activated components of the network device is greater than the second preset value, the network device can choose to receive the second uplink signal sent by the terminal at all beam positions.

[0193] In this implementation, through an intelligent beam selection strategy, network equipment can effectively balance performance, energy consumption and resource management, and improve the overall service quality.

[0194] Optionally, the configuration information further includes first indication information, used to indicate that a random access process is triggered by the first uplink signal, and the first uplink signal carries a preamble code.

[0195] Optionally, the configuration information also includes at least one of the following:

[0196] a period of the first uplink signal;

[0197] A beam association relationship between the first uplink signal and the second uplink signal;

[0198] The duration of the interval from when the network device receives the first uplink signal to when it sends the feedback signal.

[0199] It should be noted that this embodiment is Figure 4 The implementation methods of the corresponding network devices in the embodiment shown in the figure can be found in the specific implementation methods. Figure 4 In order to avoid repeated description, the relevant description of the embodiment shown will not be repeated in this embodiment, and the same beneficial effects can still be achieved.

[0200] Optionally, in the case of being awakened by the first uplink signal, after receiving a second uplink signal sent by the terminal, the method further includes:

[0201] When it is determined that the terminal does not transmit signals with the network device, the terminal enters a dormant state.

[0202] In one implementation, when the network device determines that it does not need to send a downlink signal to the terminal or receive an uplink signal sent by the terminal, it enters a dormant state, and can indicate this through configuration information sent by the network device to the terminal. This implementation can save energy consumption of the network device.

[0203] Optionally, after receiving a first uplink signal sent by the terminal and before receiving a second uplink signal sent by the terminal, the method further includes:

[0204] The main receiver is turned on, or a working module of the receiver is switched from a first working state to a second working state, wherein the power consumption of the first working state is less than the power consumption of the second working state.

[0205] In one implementation, after the network device is awakened 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., a non-low-power receiver used for normal communication) or switch the working module in the normal receiver that was previously in a low-power working state to a high-power working state.

[0206] 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 state of the receiver according to actual communication needs.
