For ease of description, the above-mentioned devices are collectively referred to as terminal devices. The number of terminal devices 10 is generally multiple, and one or more terminal devices 10 may be distributed in each cell managed by an access network device 20. In the embodiments of the present application, “terminal device” and “UE” are often used interchangeably, but those skilled in the art will understand that the two generally express the same meaning.

[0061] Access network equipment 20 is a device deployed in an access network to provide wireless communication capabilities for terminal device 10. Access network equipment 20 may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different wireless access technologies, the names of devices that provide access network equipment functions may vary. For example, in 5G NR systems, they are referred to as gNodeBs or gNBs. As communication technologies evolve, the term "access network equipment" may change. For ease of description, in the embodiments of this application, the aforementioned devices that provide wireless communication capabilities for terminal device 10 are collectively referred to as access network equipment.

The access network device 20 and the terminal device 10 communicate with each other via an air interface technology, such as the Uu interface.

[0064] The "5G NR system" in the embodiments of the present application may also be referred to as a 5G system or an NR system, but those skilled in the art will understand its meaning. The technical solutions described in the embodiments of the present application may be applicable to LTE systems, 5G NR systems, subsequent evolution systems of 5G NR systems, and other communication systems such as NB-IoT (Narrow Band Internet of Things) systems, and this application does not limit this.

[0065] In an embodiment of the present application, the network device can provide services for a cell, and the terminal device communicates with the network device through the transmission resources (for example, frequency domain resources, or spectrum resources) on the carrier used by the cell. The cell can be a cell corresponding to the network device (for example, a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0066] Before introducing the technical solutions of this application, we first introduce and explain some of the background technologies involved in this application. The following related technologies can be combined with the technical solutions of the embodiments of this application as optional solutions, and they all fall within the scope of protection of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0067] 1. UE energy saving based on PDCCH (Physical Downlink Control Channel)

[0068] In the evolution of 5G, higher requirements are placed on UE power saving. For example, for the existing DRX (Discontinuous Reception) mechanism, during each on duration, the UE needs to continuously detect the PDCCH to determine whether the base station schedules data transmission to itself. As shown in Figure 2, the DRX mechanism includes configuring a DRX cycle for the UE in the RRC_CONNECTED state (also known as the "RRC (Radio Resource Control) connection state"). A DRX cycle consists of "On Duration" and "Opportunity for DRX". During the "On Duration" time, the UE monitors and receives downlink channels and signals including PDCCH; during the "Opportunity for DRX" time, the UE does not receive downlink channels and signals such as PDCCH to reduce power consumption.

[0069] However, for most UEs, there may be no need to receive data transmission for a long time, but it is still necessary to maintain a regular wake-up mechanism to monitor possible downlink transmissions. For this type of UE, there is room for further optimization of power saving. In the relevant standards, energy-saving signals are introduced for energy saving of UEs in the RRC_CONNECTED state to achieve further energy saving. The energy-saving signal is used in conjunction with the DRX mechanism, and the UE receives an indication of the energy-saving signal before the DRX ON duration. When the UE has data transmission in a DRX cycle, the energy-saving signal "wakes up" the UE to monitor the PDCCH during the DRX On duration; otherwise, when the UE has no data transmission in a DRX cycle, the energy-saving signal does not "wake up" the UE, and the UE does not need to monitor the PDCCH during the DRX On duration. Among them, the energy-saving signal is carried on the PDCCH channel and is carried by DCIformat 2_6 (DCI (Downlink Control Information) format 2_6).

[0070] Figure 3 shows the process of using a power-saving signal to indicate whether a UE should monitor the PDCCH during the DRX On Duration. The relevant standards optimize energy conservation for UEs receiving paging messages in the RRC_IDEL / RRC_INACTIVE state (RRC idle or inactive) by introducing similar power-saving signals. When receiving paging messages via DRX, there is a paging occasion (PO) within a DRX cycle. The UE only receives paging messages during the PO and not during other times, thereby saving power. The PF (Paging Frame) indicates the system frame number in which the paging message should appear, while the PO indicates the possible time of appearance. A PF may include one or more POs. During each DRX cycle or paging cycle, the UE only needs to monitor its own PO. The UE calculates its corresponding PF and the position of the PO within the PF based on its ID. Figure 4 shows the position of the PF within a paging DRX cycle and the position of the PO within the PF.

[0071] However, in reality, the probability of a UE being paged may not be high. The UE periodically checks the PDCCH at the corresponding PO, but fails to detect the paging indication information sent to it, resulting in power waste. The energy-saving signal introduced in the relevant standards is called PEI (Paging Early Indication), which is used to indicate whether the UE will receive the paging PDCCH at the target PO before the target PO arrives. The energy-saving signal is carried on the PDCCH channel and is carried by DCI format 2_7.

[0072] As shown in FIG5 , a power saving signal indicates whether UEs in one or more paging subgroups receive paging on the corresponding PF or PO.

[0073] The relevant standards continue to enhance energy conservation for UEs in the RRC_CONNECTED state, introducing enhanced solutions for search space set group switching and power saving by skipping PDCCH detection when necessary, known as PDCCH skipping. Control information related to search space set group switching and PDCCH skipping is also carried on the PDCCH.

[0074] 2. UE energy saving based on receiver wake-up

[0075] In order to further save power for UE, relevant standards consider introducing WUR (Wake Up Receiver) to receive wake-up signals. The wake-up receiver has the characteristics of extremely low cost, extremely low complexity and extremely low power consumption. It mainly receives the wake-up signal through envelope detection. Therefore, the WUS (Wake Up Signal) received by the wake-up receiver is different from the modulation method, waveform, etc. of the signal based on PDCCH carried by the relevant standards. The wake-up signal is mainly an envelope signal that performs ASK (amplitude shift keying) modulation on the carrier signal. The demodulation of the envelope signal is also mainly based on the energy provided by the wireless radio frequency signal to drive the low-power circuit, so it can be passive. The wake-up receiver can also be powered by the UE. Regardless of the power supply method, the receiver greatly reduces power consumption compared to the traditional receiver of the UE. The wake-up receiver can be combined with the UE as an additional module of the UE receiver, or it can be used as a wake-up function module of a UE alone.

[0076] The block diagram of the receiver system based on zero-power wake-up is shown in Figure 6. The wake-up receiver receives the wake-up signal and can instruct the UE to turn on the main receiver if necessary. Otherwise, the UE's main receiver can be turned off.

[0077] The wake-up receiver does not need to be turned on and off to save power like traditional receivers. Instead, it can be activated by WUS at any time and receive the wake-up signal. The wake-up signal is mainly an envelope signal that performs ASK modulation on the carrier signal. For example, the WUS signal used in 802.11 technology uses OOK (On-Off Keying) modulation. The modulation principle of OOK is to modulate the amplitude of the carrier signal to non-zero and zero values, corresponding to On and Off, respectively, to represent the information bit. OOK is also known as binary amplitude shift keying (2ASK). As shown in Figure 7, bit 1 is modulated to On and bit 0 is modulated to Off.

[0078] Beamforming in 3.5G

[0079] In 5G systems, because the frequency band used is higher than that of LTE, the path loss of wireless signal transmission increases, and the coverage of wireless signals decreases. In this case, using beamforming technology to form beams through the base station's multi-antenna system to increase the gain of wireless signals and compensate for the path loss is a feasible method. Beams are directional, and a narrow beam can only cover part of a cell and cannot cover all users in the cell. As shown in Figure 8, the base station can send signals using four beams in different directions (B1, B2, B3, and B4 in the figure). Beam B2 only covers UE1 and not UE2.

[0080] Common channels and signals in 5G systems, such as synchronization signals and broadcast channels, must be covered throughout the entire cell using multi-beam scanning to facilitate reception by UEs within the cell. For UE-specific channels and signals, the base station uses beam management to transmit them using the appropriate beam.

[0081] Beam Management in 4.5G

[0082] In NR technology, a beam failure recovery mechanism is designed for the primary cell (PCell) and the primary secondary cell (PSCell). The UE measures the PDCCH to determine the link quality corresponding to the downlink transmission beam. If the corresponding link quality is very poor, it is considered that the downlink beam has a beam failure. The UE will also measure a set of alternative beams and select a beam that meets a certain threshold as the new beam. The UE then notifies the network of a beam failure through the Beam Failure Recovery Request (BFRQ) process and reports a new beam. After the network receives the BFRQ information sent by a UE, it knows that the UE has a beam failure and chooses to send the PDCCH from the new beam. When the UE receives the PDCCH sent by the network on the new beam, it believes that the response information from the network side has been correctly received.

[0083] In the NR protocol, determining beam failure requires collaboration between the physical layer and the MAC (Media Access Control) layer. The specific steps are as follows:

[0084] The physical layer detects the assumed block error rate (BLER) of the beam corresponding to the PDCCH. If the assumed BLER for all beams is less than the specified threshold, it is recorded as a beam failure instance (BFI) and reported to the MAC. The physical layer needs to report this to the MAC periodically. If no BFI is reported at a certain time, it is assumed that there is no BFI.

[0085] The MAC layer maintains the relevant beam failure detection timer (beamFailureDetectionTimer) and beam failure counter (BFI_COUNTER). To ensure the reliability of beam failure detection, each time the MAC layer receives a BFI report, it starts or restarts the beam failure detection timer, and the beam failure counter counts by 1. If the beam failure detection timer times out, the UE resets the counter to 0, thereby ensuring that the judgment of beam failure is based on continuous BFI reports. If the beam failure counter reaches the specified maximum value during the timer operation, the UE considers that a beam failure has occurred and initiates a random access process on the corresponding primary cell.

[0086] Because the actual BLER of a PDCCH transmission cannot be directly obtained, the UE infers the corresponding possible BLER based on the measured SINR (Signal to Interference plus Noise Ratio), which is called the assumed PDCCH BLER. The assumed PDCCH BLER is obtained by measuring the periodic CSI-RS (Channel State Information Reference Signal) of the corresponding single port. This CSI-RS measurement detects beam failure. Multiple single-port periodic CSI-RS correspond to multiple beams.

[0087] If the UE detects a beam failure, it also needs to obtain a good-quality downlink beam through measurement. The network configures the UE with a set of reference signals (such as CSI-RS signals and / or SSB (Synchronization Signal and PBCH block)) for BFD (Beam Failure Detection) in advance. Each reference signal corresponds to an alternative downlink transmit beam. The UE determines a new beam by measuring the L1-RSRP (Layer 1 Reference Signal Received Power) of these alternative beams. The network pre-configures an RSRP threshold value, and the UE selects a beam from the alternative beams whose L1-RSRP measurement value is greater than this RSRP threshold as an available new beam.

[0088] The UE needs to notify the network of the new available beam it has found so that the network knows that it can use this new beam for downlink transmission. This notification process is called BFRQ. When a beam failure occurs, the UE triggers a random access process and indicates to the network side through the random access MSG1 (message 1) that the UE has experienced a beam failure and the new beam information selected by the UE. Specifically, the network pre-configures a set of candidate beams (such as CSI-RS signals and / or SSBs) for the UE, and configures corresponding PRACH (Physical Random Access Channel) resources and random preambles for each SSB / CSI-RS. Then, when the UE determines that a beam is a new beam, it uses the PRACH resources corresponding to the new beam to send the corresponding random preamble. After receiving the preamble, the network knows that the UE has experienced a beam failure. The network will determine the new beam selected by the UE based on the received PRACH information and send a random access response on the new beam. The above random access process is based on the dedicated PRACH resources pre-configured by the network, so the random access type is non-contention random access. In an actual system, the network may not configure dedicated Beam Failure Recovery (BFR) resources (including a set of candidate beams and their corresponding dedicated PARCH resources) for the UE, or the UE may not be able to find an available new beam among the candidate beams configured by the network. There are two specific cases:

[0089] 1) The network does not configure the reference signal for NBI and the corresponding PRACH resources, that is, the UE has no alternative beam to measure;

[0090] 2) The L1-RSRP measurement values ​​corresponding to all candidate beams are worse than the threshold configured by the network.

[0091] When the above situation occurs, the UE will initiate the existing contention-based random access process to complete the reconnection with the network based on the SSB signal quality measurement results in the cell. In this case, since the network has not pre-configured a dedicated PRACH resource for the UE for beam failure requests, after the UE sends the corresponding MSG1, the network does not know whether the UE initiated the random access process due to beam failure or for other reasons. In the enhanced version of NR, in order to further enhance the beam failure recovery mechanism in this case, the UE can carry a MAC CE (MAC Control Element, media access layer control unit) dedicated to indicating BFR information in the Msg3 (message 3) or MsgA (message A) of the contention-based random access to indicate to the network side that the random access process is triggered by a beam failure. At the same time, the BFR MAC CE can also carry the new beam information selected by the UE.

[0092] In NR technology, the transmission of channels or signals has certain spatial properties to improve the coverage and performance of transmission. For UEs in idle or inactive states, the base station does not know the distribution of UEs in the cell, and the beams used for the common channels or signals it sends need to cover different areas. The base station uses beams in different directions and beam sweeping to achieve cell coverage, that is, beams in different directions are used to cover different areas in the cell at different times. For UEs in connected state, beam management is achieved through the beam management process, through beam measurement, selection, indication and other methods and processes, and the base station can obtain the appropriate downlink and uplink beams for communicating with the UE.

[0093] In order to further save power for the UE, the main receiver of the UE can be in the off state, and the wake-up receiver receives the wake-up signal to wake up the main receiver for communication. When the main receiver is turned on, the beam used for communication can be maintained according to the beam management process described above. The measurement of a beam is achieved by measuring the reference signal transmitted on this beam. When the main receiver is turned off, the UE will not be able to perform measurements and feedback. When the movement of the UE causes a change in the communication beam with the base station, it cannot be reported in time (the selected new beam cannot be reported), so that after the UE's main receiver is awakened, the base station cannot determine the appropriate beam for communicating with the UE.

[0094] Please refer to Figure 9, which shows a flow chart of a wireless communication method provided by an embodiment of the present application. The method can be executed by a terminal device. The method may include the following steps:

[0095] In step 910 , the terminal device receives at least one measurement signal through a second receiver, where different measurement signals correspond to different spatial information. The terminal device includes a first receiver and a second receiver, and the second receiver is used to receive a wake-up signal.

[0096] The first receiver and the second receiver are two different receivers. For example, the first receiver and the second receiver have different functions, such as receiving different signals. In some embodiments, the capability of the first receiver is greater than that of the second receiver. In some embodiments, the power consumption of the first receiver is greater than that of the second receiver.

[0097] In some embodiments, the second receiver is used to receive a wake-up signal. After receiving the wake-up signal, the second receiver may wake up the first receiver, ie, trigger the first receiver to switch from a non-working state to a working state.

[0098] In some embodiments, the first receiver may be the main receiver in FIG. 6 , and the second receiver may be the wake-up receiver in FIG. 6 .

[0099] In some embodiments, the measurement signal is a newly defined waveform signal, such as an envelope signal using ASK modulation, specifically, a signal generated using OOK modulation. Of course, the measurement signal can also be a signal in other forms, and the embodiments of the present application do not limit the specific form of the measurement signal.

[0100] In some embodiments, different measurement signals correspond to different spatial information, meaning that different measurement signals correspond to different beams. Exemplarily, the different beams refer to beams in different directions. In some embodiments, different measurement signals are transmitted using different beams, for example, using beams in different directions.

[0101] In some embodiments, different measurement signals use different sequences, and different sequences correspond to different spatial information. A measurement signal can be represented by a sequence, and different measurement signals can use different sequences. The second receiver detects the measurement signal by detecting the sequence. Measurement signals with different spatial information use different sequences, which are used by the second receiver to determine the spatial information corresponding to the detected measurement signal. For example, there are three different measurement signals, denoted as measurement signal 1, measurement signal 2, and measurement signal 3. These three different measurement signals correspond to beams in three different directions, for example, measurement signal 1 corresponds to beam 1, measurement signal 2 corresponds to beam 2, and measurement signal 3 corresponds to beam 3. Exemplarily, measurement signal 1 is represented by sequence 1, measurement signal 2 is represented by sequence 2, and measurement signal 3 is represented by sequence 3; wherein sequence 1, sequence 2, and sequence 3 correspond to beam 1, beam 2, and beam 3, respectively. Assuming that the second receiver detects sequence 2, it means that the spatial information corresponding to the detected measurement signal is beam 2.

[0102] In some embodiments, different measurement signals use different transmission resources, and different transmission resources correspond to different spatial information. A measurement signal can be sent using one or a group of transmission resources, and different measurement signals can be sent using different transmission resources. The second receiver determines the spatial information corresponding to the received measurement signal by determining the transmission resource used by the measurement signal. In other words, measurement signals with different spatial information use different transmission resources, such as using transmission resources at different locations. The location of the transmission resource can be determined by the time domain and / or frequency domain location. For example, as shown in Figure 10, the frequency domain locations of the transmission resources used by measurement signals with different spatial information are different. The second receiver determines the spatial information corresponding to the measurement signal based on the frequency domain location of the received measurement signal. For example, there are three different measurement signals, recorded as measurement signal 1, measurement signal 2, and measurement signal 3. The three different measurement signals correspond to beams in three different directions, for example, measurement signal 1 corresponds to beam 1, measurement signal 2 corresponds to beam 2, and measurement signal 3 corresponds to beam 3. For example, measurement signal 1 is sent using transmission resource 1, measurement signal 2 is sent using transmission resource 2, and measurement signal 3 is sent using transmission resource 3. Transmission resource 1, transmission resource 2, and transmission resource 3 correspond to beam 1, beam 2, and beam 3, respectively. Assuming that the second receiver detects the measurement signal sent on transmission resource 1, the spatial information corresponding to the detected measurement signal corresponds to beam 1.

[0103] In some embodiments, the two aforementioned methods can be combined, namely, the transmission resource and sequence used by the measurement signal are used to jointly determine the spatial information corresponding to the measurement signal. For example, different measurement signals use different combinations of transmission resources and sequences, and different combinations of transmission resources and sequences correspond to different spatial information. These different combinations of transmission resources and sequences can refer to the same transmission resources but different sequences, the same sequences but different transmission resources, or different transmission resources and sequences. For example, there are three different measurement signals, denoted as measurement signal 1, measurement signal 2, and measurement signal 3. These three different measurement signals correspond to beams in three different directions. For example, measurement signal 1 corresponds to beam 1, measurement signal 2 corresponds to beam 2, and measurement signal 3 corresponds to beam 3. Exemplarily, measurement signal 1 is represented by sequence 1 and transmitted on transmission resource 1, measurement signal 2 is represented by sequence 1 and transmitted on transmission resource 2, and measurement signal 3 is represented by sequence 2 and transmitted on transmission resource 1. The combinations of sequence 1 and transmission resource 1, sequence 1 and transmission resource 2, and sequence 2 and transmission resource 1 correspond to beam 1, beam 2, and beam 3, respectively. Assuming that the second receiver detects sequence 2 sent on transmission resource 1, it means that the spatial information corresponding to the detected measurement signal is beam 3.

[0104] In some embodiments, different measurement signals carry different control information, and different control information corresponds to different spatial information. Different measurement signals may carry different control information. After receiving a measurement signal, the second receiver determines the spatial information corresponding to the control information based on the control information carried in the received measurement signal, and uses the spatial information corresponding to the measurement signal. The different control information may be different index information, such as index information of different reference signals, such as index information of different CSI-RS and / or SSB reference signals. For example, there are three different measurement signals, denoted as measurement signal 1, measurement signal 2, and measurement signal 3. These three different measurement signals correspond to beams in three different directions. For example, measurement signal 1 corresponds to beam 1, measurement signal 2 corresponds to beam 2, and measurement signal 3 corresponds to beam 3. Exemplarily, measurement signal 1 carries index information 1, measurement signal 2 carries index information 2, and measurement signal 3 carries index information 3; wherein index information 1, index information 2, and index information 3 correspond to beam 1, beam 2, and beam 3, respectively. Assuming that the measurement signal received by the second receiver carries index information 2, it means that the spatial information corresponding to the measurement signal received by the second receiver is beam 2.

[0105] In some embodiments, the spatial information corresponding to the measurement signal is determined based on the spatial information corresponding to the reference signal that has a corresponding relationship with the measurement signal. In other words, there is a corresponding relationship between the measurement signal and the reference signal. Since different reference signals correspond to different spatial information, the spatial information corresponding to the measurement signal can be determined based on the corresponding relationship between the measurement signal and the reference signal and the spatial information corresponding to the reference signal. Exemplarily, the above-mentioned reference signals include but are not limited to reference signals such as CSI-RS and SSB. In some embodiments, the corresponding relationship between the above-mentioned measurement signal and the reference signal is a QCL (Quasi-Colocation) relationship.

[0106] In some embodiments, the correspondence between the measurement signal and the reference signal is configured by a network device. Exemplarily, the network device indicates the correspondence between the measurement signal and the reference signal, such as indicating a QCL relationship between the measurement signal and the reference signal, by sending configuration information such as RRC signaling, a system message, or a physical layer signaling to the terminal device.

[0107] In some embodiments, the correspondence between the above-mentioned measurement signal and the reference signal is predefined. For example, different transmission resources in the transmission resource set of the measurement signal have a QCL relationship with the index information of the reference signal (such as CSI-RS and / or SSB) in a predefined manner. Or, different sequences in the sequence set of the measurement signal have a QCL relationship with the index of the reference signal (such as CSI-RS and / or SSB) in a predefined manner. Or, the control information carried by the measurement signal has a QCL relationship with the index information of the reference signal (such as CSI-RS and / or SSB) in a predefined manner. Among them, the predefined manner, for example, has a QCL relationship with the index information of the reference signal (such as CSI-RS and / or SSB) in sequence according to the position of the transmission resource, sequence, and control information in the corresponding set. Taking the sequence as an example, the 8 sequences that can be used by the predefined measurement signal have a QCL relationship with the indexes 0-7 of the SSB respectively in the order of sequences 0-7. The predefined correspondence in the transmission resource and the way of carrying control information is similar.

[0108] In some embodiments, different spatial information corresponds to different beams. The terminal device determines the target beam based on the spatial information corresponding to the received measurement signal.

[0109] In some embodiments, a terminal device determines a target beam based on spatial information corresponding to a received measurement signal, including: if a single measurement signal is received, the terminal device determines the target beam based on the spatial information corresponding to the received measurement signal; or, if multiple measurement signals are received, the terminal device selects a target measurement signal from the multiple received measurement signals and determines the target beam based on the spatial information corresponding to the target measurement signal. The terminal device may select a target measurement signal from the multiple received measurement signals by random selection or by implementation of the terminal device, and this application does not limit this.

[0110] In some embodiments, the terminal device determines the target beam based on the spatial information corresponding to the received measurement signal, including: the terminal device determines the signal strength of the received measurement signal; selects a target measurement signal from the measurement signals whose signal strength is greater than or equal to the threshold value, and determines the target beam based on the spatial information corresponding to the target measurement signal. Among the one or more measurement signals received by the terminal device, if there is a measurement signal whose signal strength is greater than or equal to the threshold value, a target measurement signal is selected from the measurement signals whose signal strength is greater than or equal to the threshold value. Exemplarily, if there is only one measurement signal whose signal strength is greater than or equal to the threshold value, the measurement signal is determined as the target measurement signal; if there are multiple measurement signals whose signal strength is greater than or equal to the threshold value, one can be randomly selected from the multiple measurement signals as the target measurement signal, or the measurement signal with the largest (optimal) signal strength can be selected as the target measurement signal, or it depends on the implementation of the terminal device, which is not limited in this application. Exemplarily, the above-mentioned threshold value can be configured by the network device or predefined. For example, if the measurement signal is modulated using ASK, its high level is compared with a threshold level through a comparator to determine whether it is greater than or equal to the threshold value.

[0111] The above embodiments provide two methods for determining the target beam. In one method, considering that the second receiver may have relatively low capabilities and may only be able to receive measurement signals sent using an appropriate beam, the process of the second receiver receiving the measurement signal to determine the target beam can be based on the result of detecting the measurement signal using the beam. In another method, if the second receiver has higher capabilities, for example, the second receiver can measure signal strength, the target beam can be determined based on whether the signal strength of the detected measurement signal meets a certain threshold.

[0112] In some embodiments, when the first receiver is in a non-working state, the terminal device receives the at least one measurement signal through the second receiver. The non-working state may be a closed state, a power-off state or a sleep state, and the working state is a concept relative to the non-working state, and the working state refers to an open state, a power-on state or a non-sleep state (such as a normal working state). When the first receiver is in a working state, its power consumption is greater than that in a non-working state. In order to save power for the terminal device, the first receiver can be set to a non-working state in some cases, and when necessary (such as when the first receiver has a working demand), the first receiver can be awakened to enter a working state. By receiving the measurement signal through the second receiver for measurement during the period when the first receiver is in a non-working state, beam management during the period when the first receiver is in a non-working state is achieved.

[0113] In some embodiments, after the first receiver switches from an inactive state to an active state, the terminal device performs a beam failure recovery process. In some embodiments, during the beam failure recovery process, the terminal device may indicate the target beam determined based on the measurement signal to the network device, so that after the beam failure recovery is complete, the network device can use the target beam to send information to the terminal device.

[0114] In some embodiments, the at least one measurement signal is associated with a first BWP (Bandwidth Part); or, the at least one measurement signal is associated with a second BWP; or, the measurement signal corresponding to the at least one measurement signal is associated with the first BWP; or, the measurement signal corresponding to the at least one measurement signal is associated with the second BWP; wherein the first BWP is the BWP used after the first receiver switches from a non-operating state to an operating state, and the second BWP is the BWP used before the first receiver enters the non-operating state. Exemplarily, the association may refer to a reference signal corresponding to the at least one measurement signal being a signal configured on the first BWP or the second BWP.

[0115] The technical solution provided by the embodiment of the present application is that for a terminal device equipped with a first receiver and a second receiver, the second receiver is used not only to receive a wake-up signal but also to receive a measurement signal. Since different measurement signals correspond to different spatial information, the terminal device can perform beam management based on the measurement signal received by the second receiver to ensure that a suitable beam is used for communication between the terminal device and the network device, thereby improving communication quality and reliability.

[0116] In some embodiments, beam management is implemented during the first receiver's inactive state by using a second receiver to receive measurement signals and perform measurements while the first receiver is inactive. After the first receiver switches from the inactive state to the active state, the terminal device can perform a beam failure recovery process based on the measurement results of the second receiver. This ensures that after the second receiver resumes operation, the terminal device and the network device use the appropriate beam for communication, thereby improving communication quality and reliability.

[0117] Please refer to Figure 11, which shows a flowchart of a wireless communication method provided by another embodiment of the present application. The method can be performed by a terminal device, which includes a first receiver and a second receiver. The method can include the following steps:

[0118] Step 1110: When the first receiver is in a non-working state, if the second receiver receives a wake-up signal, the terminal device switches the first receiver from the non-working state to the working state.

[0119] Step 1120: After the first receiver switches to the working state, the terminal device performs a beam failure recovery process.

[0120] The first receiver and the second receiver are two different receivers. For example, the first receiver and the second receiver have different functions, such as receiving different signals. In some embodiments, the capability of the first receiver is greater than that of the second receiver. In some embodiments, the power consumption of the first receiver is greater than that of the second receiver.

[0121] In some embodiments, the second receiver is used to receive a wake-up signal. After receiving the wake-up signal, the second receiver may wake up the first receiver, ie, trigger the first receiver to switch from a non-working state to a working state.

[0122] In some embodiments, the first receiver may be the main receiver in FIG. 6 , and the second receiver may be the wake-up receiver in FIG. 6 .

[0123] In some embodiments, the non-working state may be a closed state, a power-off state, or a dormant state, and the working state is a concept relative to the non-working state, and the working state refers to the open state, the power-on state, or the non-dormant state (such as the normal working state). When the first receiver is in the working state, its power consumption is greater than that in the non-working state. In order to save power in the terminal device, the first receiver can be set to the non-working state in some cases, and when necessary (such as when the first receiver has a working requirement), the first receiver can be awakened to enter the working state.

[0124] In some embodiments, when the first receiver is in a non-working state, if the second receiver receives a wake-up signal from the network device, the terminal device switches the first receiver from the non-working state to the working state.

[0125] In some embodiments, after the first receiver switches to an active state, the terminal device performs a beam failure recovery process, including: after the first receiver switches to an active state, the terminal device determines a target reference signal that meets the conditions based on a beam failure detection result; and initiates a random access process using a random access resource corresponding to the target reference signal. The beam failure detection result may be obtained after the first receiver switches to an active state or while the first receiver is in an inactive state.

[0126] In some embodiments, after the first receiver of the terminal device switches to the working state, the terminal device receives at least one reference signal through the second receiver, different reference signals correspond to different spatial information (such as beams), and a target reference signal that meets the conditions is determined based on the received reference signal. Exemplarily, the signal strength of the received reference signal is measured, and a target reference signal is selected from the reference signals whose signal strength is greater than or equal to the threshold value. Exemplarily, after the first receiver of the terminal device wakes up, the reference signal (such as CSI-RS and / or SSB) is measured, and a target CSI-RS or SSB that meets the quality is determined based on the measurement results, and the random access process is initiated using the PRACH resource corresponding to the target CSI-RS or SSB.

[0127] In some embodiments, while the first receiver is in an inoperative state, the terminal device receives at least one reference signal through a second receiver. Different reference signals correspond to different spatial information (e.g., beams). A target reference signal that meets the conditions is determined based on the received reference signals. Exemplarily, the signal strength of the received reference signals is measured, and a target reference signal is selected from reference signals whose signal strength is greater than or equal to a threshold value. In this example, the second receiver has the ability to receive reference signals. The reference signal here can be understood as the measurement signal in the embodiment of FIG. 9 . For relevant technical details, please refer to the description of the embodiment of FIG. 9 and will not be repeated here.

[0128] In some embodiments, the terminal device indicates the spatial information (such as the beam) corresponding to the target reference signal to the network device by initiating a random access process. The random access process can be a non-contention-based random access process or a contention-based random access process.

[0129] In some embodiments, when the first receiver is in an inactive state, the beam failure detection timer and beam failure counter are suspended. After the first receiver switches from the inactive state to the active state, the beam failure detection timer and beam failure counter resume operation. The beam failure detection timer may be the beamFailureDetectionTimer described above, and the beam failure counter may be the BFI_COUNTER described above. Suspending the beam failure detection timer and beam failure counter means that the timer pauses timing or the counter pauses counting, but retains the current timing value or count value. After resuming operation, the timer resumes timing or counts from the current timing value or count value.

[0130] In some embodiments, after the first receiver switches from a non-operating state to an operating state, the beam failure detection timer is restarted and / or the count value of the beam failure counter is set to zero. Restarting the beam failure detection timer refers to initializing the timer value. The beam failure detection timer may be the beamFailureDetectionTimer described above, and the beam failure counter may be the BFI_COUNTER described above. When the first receiver is in the non-operating state, the beam failure detection timer and the beam failure counter are stopped. Stopping the beam failure detection timer and the beam failure counter means that the timer stops timing or the counter stops counting.

[0131] The technical solution provided by the embodiment of the present application is to trigger the execution of a beam failure recovery process for a terminal device having a first receiver and a second receiver after the first receiver switches from a non-working state to a working state. That is, the beam failure recovery process is not triggered based on a related timer or counter, but is triggered based on the wake-up of the first receiver. Since the first receiver is in the non-working state, the terminal device may move or other reasons, resulting in the beam originally used before entering the non-working state being no longer applicable after switching to the working state again after a non-working period. By executing the beam failure recovery process after the first receiver wakes up, the appropriate beam can be re-determined, thereby improving communication quality and reliability.

[0132] Please refer to Figure 12, which shows a flow chart of a wireless communication method provided by another embodiment of the present application. The method can be performed by a terminal device, which includes a first receiver and a second receiver. The method can include the following steps:

[0133] Step 1210: When the first receiver is in a non-working state, if the second receiver receives a wake-up signal, the terminal device switches the first receiver from the non-working state to the working state.

[0134] Step 1220: After the first receiver switches to the working state, the terminal device determines the BWP on which the first receiver is working, and performs beam failure detection on the BWP on which the first receiver is working.

[0135] For the introduction and description of the first receiver, the second receiver, the working state and the non-working state, please refer to the other embodiments above, which will not be described in detail in this embodiment.

[0136] When the second receiver of the terminal device receives the wake-up signal, it needs to determine the frequency domain bandwidth (e.g., BWP) of the first receiver after waking up. When the first receiver of the terminal device is turned on, it needs to operate with an active downlink BWP and an active uplink BWP. When the first receiver of the terminal device is turned off and awakened again by the wake-up signal, the BWP of the first receiver of the terminal device needs to be determined.

[0137] In some embodiments, after the first receiver switches to the working state, its working BWP can be determined using any one of the following methods 1 to 5.

[0138] Method 1: After the first receiver of the terminal device switches to an active state, it may operate with the active BWP that was last active during the last active state, that is, the active BWP that was last active before the first receiver enters an inactive state. For example, after the main receiver of the terminal device wakes up, it may operate with the active BWP that was last active during the last wake-up, that is, the active BWP that was last active before the main receiver shuts down.

[0139] Method 2: After the first receiver of the terminal device switches to an active state, its active BWP can be determined based on configuration information. For example, the BWP that is active after the primary receiver of the terminal device wakes up can be determined based on configuration information, such as the ID of the BWP that the network device configures for the terminal device to wake up the primary receiver.

[0140] Method 3: After the first receiver of the terminal device switches to the working state, the BWP it works on is predefined. In one example, the BWP that works after the main receiver of the terminal device wakes up may be a predefined BWP. For example, in the related art, the network device configures the ID of the default BWP for the terminal device through the defaultDownlinkBWP-Id information. The BWP that works after the main receiver of the terminal device wakes up may be the default BWP. In another example, in the carrier aggregation scenario, the network device configures the ID of the default activated BWP after the SCell (Secondary Cell) is activated for the terminal device through the firstActiveDownlinkBWP-Id information. After the main receiver of the terminal device wakes up, the BWP that works for the SCell may be the default activated BWP. In another example, the predefined BWP may be the BWP with the smallest or largest ID among the BWPs configured by the network device for the terminal device. Specifically, the BWPID is not equal to 0, that is, the initial BWP is excluded. Specifically, the predefined BWP may also be the initial BWP.

[0141] Mode 4: After the first receiver of the terminal device switches to the working state, the BWP it works on is the initial BWP. For example, when the terminal device is in the idle state or inactive state, the BWP it works on after the main receiver of the terminal device wakes up is the initial BWP.

[0142] Method 5: The wake-up signal can carry frequency domain information corresponding to the wake-up information, which is used to determine the BWP to be operated after the first receiver switches to the active state. For example, after the terminal device's main receiver wakes up, it operates in the BWP indicated by the frequency domain information carried in the wake-up signal. For example, as shown in Figure 13, the terminal device is configured with three BWPs: BWP1, BWP2, and BWP3. The wake-up signal carries target BWP information indicating BWP1 among the three BWPs. After the main receiver wakes up, the terminal device operates in BWP1, meaning that BWP1 is the active BWP. BWP2 and BWP3 remain inactive.

[0143] Regardless of the method for determining the BWP that the main receiver of the terminal device works after waking up, for the beam management process involved in this application, the terminal device performs BFD (beam failure detection) on the BWP that the main receiver determines to work after waking up. Specifically, in the BFD method, for example, if the BWP that the main receiver of the terminal device works after waking up is the same as the BWP before the main receiver of the terminal device was last turned off, a beam failure recovery process can be performed after the main receiver wakes up, or the beam failure detection timer and the beam failure counter can be controlled to resume operation, or the beam failure detection timer can be controlled to restart and / or the count value of the beam failure counter can be set to zero; if the BWP that the main receiver of the terminal device works after waking up is different from the BWP before the main receiver of the terminal device was last turned off, a beam failure recovery process can be performed after the main receiver wakes up, or the beam failure detection timer can be controlled to restart and / or the count value of the beam failure counter can be set to zero.

[0144] The technical solution provided by the embodiment of the present application is that, for a terminal device having a first receiver and a second receiver, after the first receiver switches from a non-working state to a working state, the terminal device determines the BWP on which the first receiver is working, and performs beam failure detection on the BWP on which the first receiver is working, so that the terminal device can perform beam failure detection on an appropriate BWP after the first receiver is awakened to determine whether the beam needs to be adjusted to ensure the communication quality and reliability between the terminal device and the network device.

[0145] Please refer to Figure 14, which shows a flowchart of a wireless communication method provided by another embodiment of the present application. The method can be executed by a terminal device. The method may include the following steps:

[0146] Step 1410, after the first receiver switches from a non-working state to a working state, the terminal device adjusts the operating state of the beam failure detection timer and / or the beam failure counter; wherein the terminal device includes a first receiver and a second receiver, and the second receiver is used to receive a wake-up signal.

[0147] For the introduction and description of the first receiver, the second receiver, the working state and the non-working state, please refer to the other embodiments above, which will not be described in detail in this embodiment.

[0148] In some embodiments, when the first receiver is in a non-operating state, the beam failure detection timer and the beam failure counter are suspended. After the first receiver switches from the non-operating state to the operating state, the terminal device controls the beam failure detection timer and the beam failure counter to resume operation. The beam failure detection timer may be the beamFailureDetectionTimer described above, and the beam failure counter may be the BFI_COUNTER described above. The suspension of the beam failure detection timer and the beam failure counter means that the timer pauses timing or the counter pauses counting, but retains the current timing value or count value unchanged. After resuming operation, the timing or counting is resumed starting from the current timing value or count value.

[0149] In the related technologies described above, the MAC layer determines whether continuous BFI reports occur by maintaining a beam failure detection timer (beamFailureDetectionTimer) and a beam failure counter (BFI_COUNTER). When a terminal device's primary receiver is powered off, it can no longer measure the reference signal used for beam management, nor can it generate BFI reports. While the primary receiver is powered off, the terminal device may move or remain stationary. During this time, the terminal device is unaware of changes in its good-quality beams. Before the terminal device's primary receiver is powered off, the beam failure detection timer and beam failure counter maintained by the terminal device's MAC layer remain running. When the terminal device's primary receiver is powered off, the beam failure detection timer and beam failure counter are suspended and remain in the same state as when the primary receiver was powered off. When the terminal device's primary receiver is powered off, the beam failure detection timer and beam failure counter resume. In other words, the beam failure detection timer and beam failure counter operate based on the BFD reference signal detection results before and after the terminal device's primary receiver is powered off, ignoring BFD operations that occurred while the terminal device's primary receiver was powered off.

[0150] In some embodiments, after the first receiver switches from a non-operating state to an operating state, the terminal device controls the restart of the beam failure detection timer and / or sets the count value of the beam failure counter to zero. The beam failure detection timer may be the beamFailureDetectionTimer described above, and the beam failure counter may be the BFI_COUNTER described above. In some embodiments, when the first receiver is in the non-operating state, the beam failure detection timer and the beam failure counter cease to run. The beam failure detection timer and the beam failure counter cease to run, which means that the timer stops timing or the counter stops counting.

[0151] When the terminal device's main receiver is turned off, it can no longer measure the reference signal used for beam management, nor can it generate a BFI report. During the period when the main receiver is turned off, the terminal device is unaware of whether the beam has changed. Unlike the aforementioned method, after the terminal device's main receiver wakes up, the terminal device re-measures the BFD reference signal and maintains the beam failure detection timer and beam failure counter based on the measurement results, regardless of the maintenance status before the terminal device's main receiver was turned off. Therefore, when the terminal device's main receiver wakes up, the beam failure detection timer maintained by the MAC layer is restarted, and the beam failure counter is set to zero.

[0152] Please refer to Figure 15, which shows a flow chart of a wireless communication method provided by another embodiment of the present application. The method can be performed by a zero-power terminal device (hereinafter referred to as a zero-power terminal). The method may include the following steps:

[0153] Step 1510: The zero-power consumption terminal receives at least one measurement signal, where different measurement signals correspond to different spatial information.

[0154] Step 1520: The zero-power consumption terminal sends indication information of the target measurement signal in the at least one measurement signal by active transmission or backscattering.

[0155] In some embodiments, different measurement signals use different sequences, and different sequences correspond to different spatial information.

[0156] In some embodiments, different measurement signals use different transmission resources, and different transmission resources correspond to different spatial information.

[0157] In some embodiments, different measurement signals carry different control information, and different control information corresponds to different spatial information.

[0158] In some embodiments, the spatial information corresponding to the measurement signal is determined based on the spatial information corresponding to a reference signal that has a corresponding relationship with the measurement signal. Exemplarily, the corresponding relationship is a QCL relationship. Exemplarily, the corresponding relationship is configured or predefined by the network device.

[0159] In some embodiments, different spatial information corresponds to different beams.

[0160] In some embodiments, the zero-power consumption terminal determines a target beam based on spatial information corresponding to a received measurement signal, where the target beam corresponds to the target measurement signal.

[0161] In some embodiments, if a measurement signal is received, the zero-power consumption terminal determines the target beam based on the spatial information corresponding to the received measurement signal; or, if multiple measurement signals are received, the zero-power consumption terminal selects a target measurement signal from the multiple measurement signals received, and determines the target beam based on the spatial information corresponding to the target measurement signal.

[0162] In some embodiments, the zero-power terminal determines the signal strength of the received measurement signal; selects a target measurement signal from the measurement signals whose signal strength is greater than or equal to a threshold value, and determines the target beam based on the spatial information corresponding to the target measurement signal.

[0163] In some embodiments, the indication information of the target measurement signal includes: identification information of the target measurement signal.

[0164] In some embodiments, the indication information of the measurement signal is carried in the measurement signal; or, the indication information of the measurement signal is determined by association information of the measurement signal. Exemplarily, the association information includes at least one of the following: a sequence used by the measurement signal, and a transmission resource used by the measurement signal.

[0165] Based on the energy source and usage of zero-power terminals, zero-power terminals can be divided into the following types:

[0166] (1) Passive zero-power terminal

[0167] Zero-power terminals do not require internal batteries. When they approach network devices (such as the reader / writer of an RFID (Radio Frequency Identification) system), they are within the near-field radiation generated by the network device's antenna. Consequently, the zero-power terminal's antenna generates an induced current through electromagnetic induction, which drives the terminal's low-power chip circuits to demodulate forward link signals and modulate backward link signals. For backscatter links, the zero-power terminal uses backscattering to transmit signals.

[0168] It can be seen that the passive zero-power terminal does not require a built-in battery to drive either the forward link or the reverse link, and is a true zero-power terminal.

[0169] Passive zero-power terminals do not require batteries, and their RF circuits and baseband circuits are very simple. For example, they do not require components such as LNA (Low Noise Amplifier), PA (Power Amplifier), crystal oscillator, and ADC (Analog to Digital Converter). Therefore, they have many advantages such as small size, light weight, low price, and long service life.

[0170] (2) Semi-passive zero-power terminal

[0171] Semi-passive zero-power terminals do not have conventional batteries themselves, but instead use RF (Radio Frequency) energy harvesting modules to harvest radio wave energy and store it in an energy storage unit (such as a capacitor). This energy storage unit then drives the low-power chip circuitry in the zero-power terminal to demodulate forward link signals and modulate backward link signals. For backscatter links, the zero-power terminal uses backscattering to transmit signals.

[0172] It can be seen that the semi-passive zero-power terminal does not require a built-in battery to drive either the forward link or the reverse link. Although energy stored in capacitors is used in operation, the energy comes from the radio energy collected by the energy harvesting module. Therefore, it is also a true zero-power terminal.

[0173] Semi-passive zero-power consumption terminals inherit many advantages of passive zero-power consumption terminals, and therefore have many advantages such as small size, light weight, low price, and long service life.

[0174] (3) Active zero-power terminal

[0175] In some scenarios, zero-power terminals can also be active zero-power terminals, which can have built-in batteries. The battery is used to drive the low-power chip circuits in the zero-power terminal, performing tasks such as demodulating forward link signals and modulating reverse link signals. However, for backscatter links, zero-power terminals use backscattering to transmit signals. Therefore, the zero-power nature of these terminal devices is primarily due to the fact that reverse link signal transmission does not require the terminal device's own power, but instead uses backscattering.

[0176] Active zero-power terminals are powered by built-in batteries to extend their communication range and improve communication reliability. Therefore, they are used in scenarios with relatively high requirements for communication distance and read latency.

[0177] In this embodiment, the zero-power terminal is an independent communication terminal, and its communication with the network device also needs to implement beam management. Among them, the measurement signal for beam failure detection can be defined in the manner of the method embodiment shown in Figure 9. During the process of beam failure recovery, the zero-power terminal is required to report a new beam to the network device for the network device to adjust the beam. Unlike the wake-up receiver mentioned earlier in this application, the zero-power terminal has a receiver and a transmitter. The way it transmits signals can be active or backscattering. As shown in Figure 16, it shows a schematic diagram of the principle of backscattering. The zero-power terminal (the backscattering tag in Figure 16) receives the carrier signal sent by the backscattering reader and collects energy through the RF energy collection module. Then the low-power processing module (the logic processing module in Figure 16) is controlled to modulate the incoming signal and perform backscattering. The main features of backscatter are as follows: (1) The terminal device does not actively transmit signals, but achieves backscatter communication by modulating the incoming signal; (2) The terminal device does not rely on traditional active power amplifier transmitters, and uses low-power computing units, greatly reducing hardware complexity; (3) It can be powered by batteries, and can also be combined with energy harvesting to achieve battery-free communication.

[0178] The zero-power terminal reports the measurement results of the measurement signal used for beam failure detection to the network device through active transmission or backscattering, for the network device to use for beam management. Specifically, the identification information of the measurement signal used for beam failure detection can be reported. The identification information is explicitly carried by the measurement signal or implicitly determined by the sequence of the measurement signal, transmission resources, etc., where the sequence of the measurement signal, transmission resources, and identification information have a corresponding relationship, which is predefined or network-configured.

[0180] The technical solution provided in the embodiment of the present application proposes a beam management solution for zero-power terminals by measuring measurement signals and feeding back target measurement signals to network devices through active emission or backscattering, so that the zero-power terminals and network devices can also communicate using appropriate beams, thereby improving communication quality and reliability.
