Description

[Technical field]

The present application relates to the field of communications technology, and in particular to a method, an apparatus and a communications device operating the communications device. [Background technology]

[0002] In the design of a communication system, different states of a terminal (User Equipment, UE), such as an idle state (IDLE) and a connected state (CONNECTED), are introduced. After transmitting or receiving data, the UE can transition from the CONNECTED state to the IDLE state to save power. In the IDLE state, the UE only needs to receive necessary synchronization information, paging information, and system broadcast information (System Information Block, SIB), etc. Compared with the CONNECTED state, the power can be significantly reduced, typically reaching a level of several tens of mW, which is less than one tenth of the CONNECTED state.

[0003] However, the IDLE state design still requires the terminal to periodically turn on the transceiver and the corresponding modem (MODEM) signal processing module to properly process the received signal, but since these radio frequency (RF) and MODEM modules cannot actually be completely turned off, the communication power consumption in the IDLE state cannot be reduced.

[0019] Referring to Fig. 1, Fig. 1 shows a block diagram of a wireless communication system to which the embodiment of the present application can be applied. The wireless communication system includes a terminal 11 and a network side device 12. Here, the terminal 11 may be called a terminal device or a user terminal (User Equipment, UE), and the terminal 11 may be a terminal side device such as a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a mobile internet device (Mobile Internet Device, MID), a wearable device, or an in-vehicle device, and it should be noted that the embodiment of the present application does not limit the specific type of the terminal 11.The network side device 12 may be a base station or a core network, where the base station may be a base station of 5th-Generation (5G) and later versions (e.g., NR node (gNB), 5G NR NB, etc.), or a base station in other communication systems (e.g., Evolved B node (eNB), Wireless Local Area Networks (WLAN) access point, or other access point, etc.), or a location server (e.g., Enhanced Serving Mobile Location Centre (E-SMLC) or Location Manager Function (LMF)), where the base station may be a Node B, Evolved Node B, access point, Base Transceiver Station (BTS), radio base station, radio transceiver, Basic Service Set (BSS), Extended Service Set (LSB), or other service set (SP). The base station may be called a wireless LAN access point (WLAN) or a wireless set (ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a wireless fidelity (WiFi) node, or any other suitable term in the art, and as long as the same technical effect is achieved, the base station is not limited to a specific technical term, and it should be explained that in the embodiments of the present application, only a base station in an NR system is taken as an example, but the embodiments of the present application are not limited to a specific type of base station and a specific communication system. In the description of the embodiments of the present application, it may be transmission and reception between a terminal and a base station, or transmission and reception between two terminals, i.e., terminal 1 and terminal 2, or other non-cellular phone communication system transmission and reception nodes, such as a sensor receiving device and a launching device, etc.

[0020] Because mobile phones and networks communicate with each other through radio channels and exchange large amounts of information with each other, they require a control mechanism to exchange configuration information and reach an agreement, and such a control mechanism is Radio Resource Control (RRC). In order for terminals to maintain a relatively fixed communication state, different RRC states are introduced in related communication systems, such as: In New Radio (NR), RRC has three states: IDLE, INACTIVE, and CONNECTED.

[0021] Long Term Evolution (LTE) only has two RRC states: RRC IDLE and RRC CONNECTED. NR introduces a new state -- RRC INACTIVE.

[0022] The above states can be converted into each other.

[0023] In the above IDLE state design, the terminal still needs to periodically turn on the transceiver and the corresponding MODEM signal processing module to properly process the received signal, but since these RF and MODEM modules cannot be completely turned off, the communication power consumption in the IDLE state cannot be reduced.

[0024] To significantly reduce the power consumption of communication reception by reducing the reception activity in the RRC IDLE state and by certainly turning off the RF and MODEM modules, a near-zero power receiver can be introduced in the terminal's reception module. This near-zero power receiver does not require the complex signal detection (e.g., amplification, filtering, quantization, etc.) of the RF module and the signal processing of the MODEM, but relies only on passive matched filtering and relatively low power signal processing.

[0025] On the base station side, by triggering a wake-up signal (WUS) on-demand, a receiver with power close to "zero" can be activated to know the activation notification, thereby triggering a series of flows inside the terminal, such as turning on modules such as radio frequency transmission / reception and baseband processing.

[0026] Such wake-up signals are typically some relatively simple on-off keying signal, so that the receiver can learn of the wake-up announcement by a process such as simple energy detection, followed by possible sequence detection identification.

[0027] An embodiment of the present application provides an operating method for a communication device, which is performed by a first communication device, and includes the following steps, as shown in FIG.

[0028] Step 101: receiving a sleep state transition command for a second communication device; and determining that the first communication device satisfies a preset sleep state transition condition.

[0029] In an embodiment of the present application, when a predetermined condition is satisfied, the first communication device converts from a non-sleep state to a sleep state; in the sleep state, the first communication device detects a wake-up signal, and there is no need to perform other physical layer processes, which can save the power consumption of the communication device; when the sleep state needs to be cancelled, the wake-up signal instructs the first communication device to convert to a non-sleep state, which can ensure the communication quality of the first communication device.

[0030] In some embodiments, In the sleep state, the first communication device at least detects a wake-up signal, where the sleep state is a state different from RRC IDLE, INACTIVE or CONNECTED, and optionally, in the sleep state, the MODEM module is in an off state to save electrical energy.

[0031] In the non-sleep state, the first communication device does not detect a wake-up signal and executes a physical layer process in a radio resource control (RRC) idle state IDLE, a deactivation state INACTIVE or a connected state CONNECTED.

[0032] In this embodiment, in the sleep state, the first communication device can only detect the wake-up signal, so as to achieve the purpose of saving the power consumption of the communication device, and in the non-sleep state, the first communication device performs the physical layer process in other states.

[0033] Here, for each state, the physical layer process to be performed is as follows:

[0034] 1. RRC_IDLE (Idle mode): The UE selects a Public Land Mobile Network (PLMN), The UE receives the broadcast system information; Cell reselection mobility, Mobile terminated data paging is initiated by the 5th Generation Mobile Communication Technology Core Network (5GC) Paging of the mobile termination data area is managed by the 5GC, Discontinuous Reception (DRX) for Core Network (CN) paging deployed by the Non Access Stratum (NAS).

[0035] 2. RRC_INACTIVE (inactive mode): PLMN selection, Broadcast system information, Cell reselection mobility, Paging is initiated by NG-RAN (RAN Paging), Notification areas (RNAs) based on wireless access networks (RANs) are managed by NG-RANs, RAN Paging DRX deployed by NG-RAN; Establishing a 5GC-NG-RAN connection (including a control plane and / or a user plane) for the UE; UE Access Stratum (AS) messages are stored in the NG-RAN and the UE, The NG-RAN knows the RNA to which the UE belongs.

[0036] 3. RRC_CONNECTED (connected mode): Establishing a 5GC-NG-RAN connection (including a control plane and / or a user plane) for the UE; The UE AS message is stored in the NG-RAN and the UE, The NG-RAN knows the cell to which the UE belongs, Transmitting unicast data to the UE; It includes measurements and the network controls the mobility.

[0037] In some embodiments, the sleep state transition condition is: The received signal quality of the first communication device is higher than a first threshold or the received signal quality of the first communication device is lower than a second threshold; The first communication device has not experienced a cell reselection within a first preset time period; and A fluctuation range of the received signal quality of the first communication device within a second preset time period is smaller than a third threshold value; the first communication device has not received a paging message or a system message within a third preset time period; and The time during which the first communications device is continuously present in at least one state other than the sleep state exceeds a first preset time length.

[0038] Here, the first threshold, the second threshold, the first preset time period, the second preset time period, the third threshold, the third preset time period, and the first preset time length may be pre-configured, configured by the network side, or defined by a protocol.

[0039] The received signal quality may be measured by Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Received Signal Strength Indication (RSSI), Pathloss, or Signal to Interference plus Noise Ratio (SINR), but is not limited to being measured using the above parameters.

[0040] The at least one state other than the sleep state may be an IDLE state or an INACTIVE state.

[0041] In some embodiments, the method further comprises: The method further includes reporting auxiliary information to the second communication device for determining whether or not the second communication device transmits a sleep state transition command to the first communication device, the auxiliary information being: a signal strength or signal quality of the first communication device; and a mobility status of the first communication device.

[0042] After receiving the auxiliary information, the second communication device can determine whether or not to instruct the first communication device to enter a sleep state based on the auxiliary information. Since the auxiliary information is related to the communication quality of the first communication device, the first communication device can be prevented from entering a sleep state when this would affect the communication quality. In this way, the communication quality of the first communication device can be guaranteed while also saving power consumption of the first communication device. In some embodiments, before or after converting from a non-sleep state to a sleep state, the method further comprises: The method further includes transmitting first instruction information to the second communication device to instruct the first communication device to enter a sleep state.

[0043] In this embodiment, the first communication device can send the first instruction information to the second communication device before converting from the non-sleep state to the sleep state, in this manner, the first instruction information can further be a request that the first communication device wishes to convert from the non-sleep state to the sleep state, or the first communication device can send the first instruction information to the second communication device after converting from the non-sleep state to the sleep state, in this manner, the first instruction information can be a notification that the first communication device will convert from the non-sleep state to the sleep state.

[0044] Alternatively, if the first communication device determines that a preset sleep state conversion condition is satisfied, the first communication device converts from a non-sleep state to a sleep state. Since this method is a method in which the first communication device autonomously converts, the first communication device can transmit first instruction information to the second communication device before or after converting from the non-sleep state to the sleep state. Specifically, the first communication device can transmit the first instruction information to the second communication device before converting from the non-sleep state to the sleep state, or the first communication device can transmit the first instruction information to the second communication device after converting from the non-sleep state to the sleep state.

[0045] In this way, after the first communication device has entered a sleep state, the first communication device can notify the second communication device that it has already entered a sleep state, thereby enabling the second communication device to know the state of the first communication device in a timely manner and avoiding the second communication device sending unnecessary signaling to the first communication device.

[0046] In some embodiments, the first instruction information comprises: A Random Access Channel (RACH), A sounding reference signal (SRS), A reference signal (SR), A Physical Uplink Shared Channel (PUSCH); A predefined physical channel; It is carried by one of the predefined physical signals.

[0047] In some embodiments, the method further comprises: The method further includes receiving second instruction information of the second communication device, instructing the second communication device to refuse to enter the sleep state.

[0048] In this embodiment, the second communication device can refuse the first communication device to be converted from a non-sleep state to a sleep state. Optionally, the first communication device may send first instruction information to the second communication device before converting from a non-sleep state to a sleep state, the first instruction information being a request to convert from a non-sleep state to a sleep state, and at this time, the second communication device can send second instruction information to the first communication device to instruct the first communication device to refuse to enter the sleep state. It should be noted that the second communication device can further send a sleep state conversion command to indicate that the first communication device agrees to enter the sleep state.

[0049] In this way, if the second communication device determines that the first communication device cannot enter a sleep state, the second communication device can send second instruction information to instruct the first communication device not to enter a sleep state, thereby ensuring the communication quality of the first communication device.

[0050] In some embodiments, the method further comprises: receiving a third message on the second communication device; and The method further includes obtaining configuration information of the wake-up signal based on the third message.

[0051] In this way, the first communication device can obtain the arrangement information of the wake-up signal through the third message and detect the wake-up signal based on the arrangement information of the wake-up signal.

[0052] In some embodiments, the third message carries configuration information for a wake-up signal, the configuration information comprising: Sequence information of the wake-up signal (e.g., basic sequence, scrambling code information, etc.); Frequency domain information of the wake-up signal; Parameter configurations that trigger state transitions (such as timer configurations), and placement of a beacon signal.

[0053] Here, the third message may be a dedicated signaling or a public signaling, and may include configuration information of at least one wake-up signal.

[0054] In some embodiments, the third message carries configuration information of a wake-up signal, or the third message carries information for calculating configuration information of a wake-up signal, and the configuration information of the wake-up signal is A time domain resource of the wake-up signal, including a reception period and an offset amount in time, etc.; A frequency domain resource of the wake-up signal, including a frequency domain density, and a code domain resource of the wake-up signal.

[0055] Here, the third message may be a dedicated signaling or a public signaling, and may include configuration information of at least one wake-up signal.

[0056] The third message may directly carry the configuration information of the wake-up signal, or may carry information for calculating the configuration information of the wake-up signal. When the third message carries information for calculating the configuration information of the wake-up signal, the first communication device can calculate resource information for receiving the wake-up signal, including a time position, a frequency domain position, a code resource, etc., based on the "information for calculating the configuration information of the wake-up signal" in combination with information such as an identifier of the first communication device.

[0057] In some embodiments, after entering the sleep state, the method further comprises: The method further includes periodically detecting a wake-up signal based on the configuration information of the wake-up signal, or constantly detecting a wake-up signal.

[0058] When detecting the wake-up signal, the first communication device can detect the wake-up signal according to a predetermined period, and can also detect the wake-up signal constantly. Here, the predetermined period may be configured by the network side, or may be configured in advance, or may be defined by a protocol, and detecting the wake-up signal according to the predetermined period can further save the power consumption of the first communication device. In some specific examples, the first communication device can periodically detect the wake-up signal on the target time-frequency resource.

[0059] In some embodiments, after entering the sleep state, the method further comprises: turning off a main receiver for receiving downlink information in a non-sleep state; and turning on a dedicated receiver for detecting a wake-up signal in the sleep state.

[0060] After entering the sleep state in this way, the first communication device can turn on only the dedicated receiver, thereby saving the power consumption of the first communication device.

[0061] In some embodiments, the method further comprises: Further comprising performing downlink synchronization by a dedicated receiver, the signal for downlink synchronization being different from the wake-up service WUS signal.

[0062] After entering the sleep state in this way, the first communication device can still use the dedicated receiver to perform downlink synchronization, and the communication quality of the first communication device can be guaranteed.

[0063] In some embodiments, the method further comprises: The method further includes performing at least one of radio resource measurement and downlink synchronization in response to the wake-up signal.

[0064] In this way, the first communication device can further use the wake-up signal to perform radio resource measurement or downlink synchronization, and the utilization rate of the wake-up signal can be improved, and there is no need to add an extra signal to perform radio resource measurement or downlink synchronization, so that signaling overhead can be saved. When using the wake-up signal to perform downlink synchronization, the network side transmits a wake-up signal once at regular intervals, and at this time, the wake-up signal may only synchronize the wake-up signal without waking up the first communication device.

[0065] In some embodiments, the information carried by the wake-up signal includes: wake-up instruction information for instructing the first communication device to wake up; sleep instruction information for instructing the first communication device to sleep; and synchronization information.

[0066] In some embodiments, if the wake-up signal indicates a wake-up of the first communication device, the method further comprises: Further comprising entering a non-sleep state.

[0067] In an embodiment of the present application, the first communication device may be a mobile terminal, and the second communication device may be a network side device or a mobile terminal or a network node; or The first communication device may be a receiving node of a communication system, and the second communication device may be a transmitting node of a communication device, for example the first communication device is a sensor receiving device and the second communication device is a sensor launching device, etc.

In the embodiment of the present application, the operating method of the communication device according to the embodiment of the present application is described by taking the execution and loading of the operating method of the communication device by the operating device of the communication device as an example.

[0071] In some embodiments, In the sleep state, the first communication device detects at least a wake-up signal; In the non-sleep state, the first communication device does not detect a wake-up signal and executes a physical layer process in a radio resource control (RRC) idle state IDLE, a deactivation state INACTIVE or a connected state CONNECTED.

[0072] In this embodiment, in the sleep state, the first communication device can only detect the wake-up signal, so as to achieve the purpose of saving the power consumption of the communication device, and in the non-sleep state, the first communication device performs the physical layer process in other states.
