[0002] This application relates to the field of wireless communication, and more particularly to a method, apparatus and system for beam management. Background Technology

[0003] With the development of mobile communication technology, the demand for communication speed and capacity is increasing. The 3rd Generation Partnership Project (3GPP) incorporates high-frequency bands into the system design considerations for next-generation new radio (NR) systems. To combat path loss in high-frequency scenarios, beamforming techniques will be increasingly used to improve gain.

[0004] Different transmit beams from transmitting equipment and different receive beams from receiving equipment can form different beam pair links for communication. The communication quality may vary depending on the beam pair link. How to establish or maintain suitable beam pair links to provide good communication quality has become an important research topic.

[0005] In existing technologies, the above problems can be solved through beam management operations such as beam sweeping and beam tracking. For details, see [link to relevant documentation]. Figure 1 As shown, taking the downlink as an example, the base station's transmit beam set includes transmit beam 1, transmit beam 2, and transmit beam 3, while the terminal's receive beam set includes receive beam a, receive beam b, and receive beam c. The base station can transmit signals sequentially through transmit beams 1 to 3 at certain time intervals to cover terminals within a certain area.

[0077] It should be understood that the above signal metric can be a layer 1 measurement result based on a synchronization signal block measurement. Alternatively, the above signal metric can be a layer 1 measurement result based on a channel state information reference signal measurement. It should be understood that the signal metric corresponding to the optimal receive beam can also include any combination of the above optional implementations.

[0078] It should be understood that by using the above technical solutions, the baseband processor can determine whether to trigger the reconfiguration action according to whether the signal metric corresponding to the updated receive beam set meets the communication requirement of the terminal, so as to guarantee the received signal quality.

[0080] Based on this, in an optional implementation, the terminal includes a sensor, and the baseband processor is further configured to acquire state information of the sensor of the terminal to determine the change in the motion state of the terminal.

[0081] It should be understood that the state information of the sensor of the terminal can be a motion state record of the terminal, and the processing unit determines whether the terminal has a change in the motion state according to the read motion state record of the terminal. Alternatively, it can also be an indication of whether the terminal is in motion generated by the sensor, and the baseband processor determines whether the terminal has a change in the motion state according to the indication.

[0082] It should be understood that with the technical solution described above, the baseband processor can determine whether to trigger a reconfiguration action according to whether the change in the motion state of the terminal is within a predefined range, so as to guarantee the quality of the received signal.

[0083] It should be understood that any optional implementation of the ninth aspect described above can be combined with each other. The baseband processor can trigger a reconfiguration action when any of the trigger conditions described above is met, reconfigure the set of receive beams of the serving cell, and the reconfigured set of receive beams of the serving cell includes the first receive beam and the second receive beam. Alternatively, the reconfigured set of receive beams of the serving cell includes the first receive beam and another receive beam. With the technical solution described above, the trigger condition can be reduced to further guarantee the quality of the received signal.

[0084] With the technical solution provided in the ninth aspect or any optional implementation described above, in an optional implementation, the baseband processor is specifically configured to determine the optimal receive beam of the serving cell once in the set of receive beams of the serving cell in one discontinuous reception (DRX) cycle. In an optional implementation, the baseband processor is specifically configured to determine the optimal receive beam of the serving cell once in the set of receive beams of the serving cell in one discontinuous reception (DRX) cycle.

[0085] In an optional implementation of any of the above ninth aspect, the terminal is configured to receive downlink messages of the updated serving cell via one or more of the set of receive beams of the updated serving cell. In an optional implementation, the terminal is configured to determine an optimal receive beam or perform receive beam tracking among one or more of the set of receive beams of the updated serving cell. In an optional implementation, the terminal is configured to measure the signal quality of the updated serving cell via one or more of the set of receive beams of the updated serving cell.

[0086] In a tenth aspect, a wireless communication system is provided, which includes a wireless network device and an apparatus as provided in the second aspect or any of the optional implementations, or an apparatus as provided in the fifth aspect or the sixth aspect, or a terminal as provided in the ninth aspect.

[0087] It should be understood that in the technical solutions provided in any of the above aspects or any of the optional implementations, a beam can be understood as a communication resource.

By using the technical solutions of the embodiments of the present application, the power consumption of the terminal can be reduced. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0101] The technical solutions provided by the present application will be further described below in conjunction with the drawings and embodiments. It should be understood that the system structure and service scenarios provided in the embodiments of the present application are mainly used to illustrate possible implementation modes of the technical solutions of the present application, and should not be interpreted as the only limitation of the technical solutions of the present application. Those skilled in the art can know that the technical solutions provided by the present application are also applicable to similar technical problems as the system structure evolves and new service scenarios appear.

[0102] It should be understood that the beam management solutions provided by the embodiments of the present application include a beam management method, apparatus and system. Since the principles of these technical solutions for solving problems are the same or similar, in the following introduction of specific embodiments, some repeated parts may not be described again, but should be regarded as mutual reference between these specific embodiments, which can be combined with each other.

[0103] In order to facilitate understanding of the embodiments of the present application, some terms will be briefly explained below to facilitate understanding by those skilled in the art.

[0104] Beam: A beam is a kind of communication resource, which can be a wide beam, a narrow beam, or other types of beams. Different beams can be considered as different communication resources, and the same information or different information can be transmitted through different beams. Alternatively, a beam can also be understood as different numbered synchronization signal blocks (SSBs) transmitted by the same transmitting end device. Alternatively, a beam can also be understood as different antenna ports. Alternatively, multiple beams with the same or similar communication characteristics can be considered as one beam. For example, a transmitting beam can refer to the signal strength distribution of a signal formed in different directions in space after the signal is transmitted by an antenna, and a receiving beam can refer to the signal strength distribution of a wireless signal received by an antenna in different directions in space. It can be understood that one or more antenna ports forming a beam can also be regarded as an antenna port set, and a beam can also be referred to as a spatial filter. A transmitting beam can also be referred to as a spatial transmission filter, and a receiving beam can also be referred to as a spatial reception filter.

[0105] Beam pair link is established on the basis of the concept of beam. A beam pair link usually includes a transmitting beam of a transmitting end device and a receiving beam of a receiving end device. If not specified, the transmitting beam in the following can be understood as the transmitting beam of the network device, and the receiving beam can be understood as the receiving beam of the terminal.

[0106] Figure 1 A structural schematic diagram of a communication system provided by an embodiment of the present application is shown. Figure 1 A wireless communication system 00 composed of a wireless network device 01 and a terminal 02 is shown. It should be understood that although Figure 1 Only one wireless network device and one terminal are shown, the wireless communication system can also include other numbers of wireless network devices and terminals, and can also include other network devices.

[0107] The wireless communication system 00 can be an example of a mobile communication system based on the 3rd Generation Partnership Project (3GPP) technical specification, and can also cover wireless communication systems based on other wireless communication standards, such as the Institute of Electrical and Electronics Engineers (IEEE) 802 series, such as 802.11, 802.15, 802.20, etc.

[0108] The wireless network device is a computing device with wireless communication function, which can generate beams with different directions by beamforming and other technologies to cover the cell 03 and communicate with terminals in different directions within the cell 03. It should be understood that the wireless network device can be a wireless access network device such as a base station. The base station can be a general node B (gNB) in the 5G mobile communication system, an evolutional node B (eNB or eNodeB) in the 4G mobile communication system, and a base station in other possible wireless access technologies. The physical form and transmission power of the base station can also be various, such as a macro base station or a micro base station.

[0109] The terminal can also be referred to as a user equipment (UE), a mobile station (MS) or a subscriber unit (SU). The terminal can be, but is not limited to, a mobile phone, a tablet computer, a laptop computer, a wearable device (a smart watch, a smart bracelet, a smart helmet, smart glasses, etc.), and other communication devices with wireless access capability, such as various Internet of Things devices, including smart home devices (smart meters, smart home appliances, etc.), smart vehicles, etc.

[0110] The cell can be a serving cell or an intra-frequency neighboring cell or an inter-frequency neighboring cell. The intra-frequency neighboring cell and the inter-frequency neighboring cell can also be referred to as a neighboring cell. It should be understood that the "serving cell" in the present application can also be referred to as "this cell", and the "neighboring cell" in the present application can also be referred to as "non-serving cell", without affecting the understanding of its technical meaning.

[0111] It should be understood that the wireless communication system structure in Figure 1 The wireless communication system structure in the present application is only an exemplary embodiment in the present application, and the communication system structure in the present application includes but is not limited to the above communication system structure.

[0112] Figure 2 A structure diagram of a synchronization signal block provided by the present application is shown in FIG. 2. As shown in FIG. 2, the synchronization signal block includes a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). Figure 2As shown, in an NR communication system, the primary synchronization signal, secondary synchronization signal, and physical broadcast channel together constitute a single SSB. An SSB occupies four orthogonal frequency division multiplexing (OFDM) symbols in the time domain and 240 consecutive subcarriers, or 20 physical resource blocks, in the frequency domain. The subcarrier spacing of an SSB can be one of 15 kHz, 30 kHz, 120 kHz, or 240 kHz. 15 kHz and 30 kHz are used for frequencies below 6 GHz, while 120 kHz and 240 kHz are used for frequencies above 6 GHz.

[0113] Figure 3 This is a schematic diagram of the structure of a synchronization signal burst set provided in an embodiment of this application. Figure 3 As shown in the upper part, a synchronization signal burst set (SS burst set) can consist of at most L (L≥1) SSBs, and the synchronization signal burst set can be transmitted periodically. The value of L is related to the frequency band; in frequency bands below 6 GHz, the maximum value of L is 8, and in frequency bands above 6 GHz, the maximum value of L is 64. SSBs within a synchronization signal burst set should be transmitted within a 5-millisecond (ms) window. During the initial dwell phase, the synchronization signal burst set is transmitted according to a predefined synchronization signal burst set period (default SS burst set period), where the predefined period is 20 ms.

[0114] like Figure 3 As shown in the lower part, the wireless network device can use different transmit beam directions to sequentially transmit SSBs with different numbers within the synchronization signal burst transmission cycle, or it can use the same transmit beam direction to sequentially transmit SSBs with the same number between synchronization signal burst transmission cycles. It should be understood that the different numbered synchronization signal blocks in this embodiment can also be understood as supporting transmit beam scanning in different directions. In frequency bands below 6 GHz, the base station can support up to 8 transmit beam scans, and in frequency bands above 6 GHz, the base station can support up to 64 transmit beam scans.

[0115] The terminal can have different received signal strengths of the SSB signals received through different beam pairs. In order to select the optimal receiving beam or the optimal beam pair, the terminal in the idle state or the inactive state receives and measures the corresponding SSBs through the corresponding receiving beams within a certain time period according to a predetermined manner, and determines the optimal receiving beam according to the measurement results corresponding to each receiving beam or each beam pair. In combination with Figure 1 For example, for the downlink, the terminal can be configured with receiving beam a, receiving beam b, and receiving beam c to receive different SSBs in at least three synchronization signal burst sets periodically transmitted by the base station in sequence, and measure the SSBs received by each receiving beam. If there are L SSBs in each synchronization signal burst set, each receiving beam corresponds to at most L SSB measurement results. The optimal receiving beam is determined according to the corresponding measurement results (for example, signal-to-interference-and-noise ratio).

[0116] In the actual environment, the wireless communication channel between the wireless network device and the terminal can be blocked due to the existence of obstacles, in other words, the existence of obstacles can cause some beam pairs to be blocked, and the communication quality obtained by communicating through the blocked beam pairs is poor. For the terminal, the obstacle can be close, for example, in the scenario of holding the terminal, the hand can be the obstacle; in the scenario of placing the terminal parallel to the desktop, the desktop can be the obstacle. The obstacle can also be far away, for example, high-rise buildings, vehicles, pedestrians, trees and other objects in the daily environment.

[0117] When all the beam pairs corresponding to one or more receiving beams of the terminal are blocked, according to the prior art, the terminal still receives and measures the SSBs through the receiving beams to determine the optimal receiving beam and the optimal beam pair. This not only wastes the power consumption of the terminal, but also can reduce the speed of determining the optimal receiving beam and the optimal beam pair.

[0118] In summary, the beam management scheme in the prior art wastes a certain power consumption and reduces the speed of determining the optimal receiving beam and the optimal beam pair, which does not meet the demand of the NR system for low power consumption. In order to solve the above problems, the embodiments of the present application provide a device, method and system for configuring receiving beams according to the measurement results of the received signals to reduce the power consumption of the terminal.

[0119] Figure 4A schematic diagram of an active period and a dormant period in a discontinuous reception cycle is provided for an embodiment of the present application. In order to save power consumption, a discontinuous reception (DRX) method is introduced. The DRX can be understood as that the terminal only turns on the receiver to enter the active period at necessary time to receive the downlink data and signaling. While at other time, the receiver is turned off to enter the dormant period to stop receiving the downlink data and signaling to save power consumption. As shown in Figure 4 , the cycle of the DRX can be a short cycle of the DRX, and when the short cycle timer of the DRX expires, a long cycle of the DRX is used. It should be understood that when the terminal enters the active period, in order to guarantee the reception quality of the downlink signal, the downlink data and signaling can be received through the optimal reception beam. Therefore, the reception beam tracking can be performed once in each DRX cycle to confirm the optimal reception beam once.

[0120] Figure 5 A method flowchart of beam management is provided for an embodiment of the present application. The method can be performed by a communication device, which can be a terminal or a chip that can be arranged in the terminal. The chip can be specifically a baseband processor or a system on chip (SoC). As shown in Figure 5 , the method comprises:

[0121] S501: determining an optimal reception beam of a serving cell in a reception beam set of the serving cell, wherein the reception beam set of the serving cell comprises a first reception beam and a second reception beam.

[0122] The first reception beam can be one or more reception beams, and the second reception beam can also be one or more reception beams. In addition, the reception beam set of the serving cell can further comprise other reception beams. The method of determining the optimal reception beam of the serving cell in the reception beam set of the serving cell of the terminal can be specifically that each reception beam in the reception beam set is configured to the terminal to receive a plurality of periodic synchronization signal burst sets from a wireless network device in turn respectively, and according to the measurement results corresponding to each reception beam, the beam pair link with the maximum measurement result is selected as the optimal beam pair link, and the corresponding reception beam is the optimal reception beam. Or, the linear average value of all measurement results corresponding to the reception beam can be taken in units of beam pair link, and the reception beam with the maximum value after the linear average of the corresponding measurement result is the optimal reception beam.

[0123] S502: receiving a downlink message of the serving cell through the optimal reception beam.

[0124] The communication device can receive a downlink message of the serving cell through the optimal receiving beam. For example, the baseband processor configures the parameter of the radio frequency receiving circuit through the interface circuit to receive the downlink message of the serving cell through the optimal receiving beam. Here, the parameter of the radio frequency receiving circuit can be understood as the parameter of the phase shifter, and can also be understood as the antenna array element weight used for calculation.

[0125] S503: When the first receiving beam is determined as the optimal receiving beam of the serving cell for a plurality of times continuously, updating the receiving beam set of the serving cell, and the updated receiving beam set of the serving cell only includes the first receiving beam.

[0126] It should be understood that the method of judging that the first receiving beam is determined as the optimal receiving beam of the serving cell for a plurality of times continuously can be specifically implemented by setting the software code in the communication device. For example, a counter is set to M (M≥1) in the related software module implementing the software algorithm, and when the first receiving beam is confirmed as the optimal receiving beam of the serving cell once, the counter is reduced by 1. In the next adjacent judgment, if the first receiving beam is again confirmed as the optimal receiving beam of the serving cell, the counter is reduced by 1 again, otherwise, the counter returns to M. When the counter is cleared, the updating action is triggered. Alternatively, it can also be implemented by setting the parameters of the hardware circuit or device in the communication device or connected thereto, for example, a timer is set to T1 (T1≥1), and the value of T1 can be predefined by the terminal, which can be greater than or equal to the time corresponding to M times of judging whether the first receiving beam is the optimal receiving beam of the serving cell. Before the timer expires, if the first receiving beam is confirmed to be not the optimal receiving beam of the serving cell, the timer returns to T1, otherwise, if the first receiving beam has been confirmed to be the optimal receiving beam of the serving cell before the timer expires, the updating action is triggered. Alternatively, it can also be implemented by setting the related software module of the software algorithm and the parameters of the above-mentioned hardware circuit or device. For example, the timer in the SoC chip is set to the time length corresponding to the period (such as the short period) of DRX, and the counter is set to M (M≥1) in the related software module implementing the software algorithm. The timer is reduced by 1 every time it expires, and when the counter is reduced to 0, the updating action is triggered.

[0127] By adopting the above technical solutions, in the next period of time, the receiving beam tracking can not be performed again, and the downlink message (such as a paging message) of the serving cell can be received through one or more receiving beams in the first receiving beam, thereby reducing the power consumption of the terminal. Alternatively, in the next period of time, the receiving beam tracking can be performed in the first receiving beam to determine the optimal receiving beam of the serving cell, thereby reducing the power consumption of the terminal while also speeding up the beam tracking.

[0128] In an alternative embodiment, after the set of receive beams of the serving cell is updated, the method further comprises:

[0129] S504a, after the predefined time duration, reconfiguring the set of receive beams of the serving cell, the reconfigured set of receive beams of the serving cell comprising the first receive beam and the second receive beam.

[0130] In an alternative embodiment, after the set of receive beams of the serving cell is updated, the method further comprises:

[0131] S504b, after the predefined time duration, reconfiguring the set of receive beams of the serving cell, the reconfigured set of receive beams of the serving cell comprising the first receive beam and other receive beams.

[0132] It should be understood that the other receive beams can be the same as one or more of the second receive beams, or can be completely different from the second receive beams.

[0133] The communication environment in which the terminal is located can change after a certain time duration, and the set of receive beams comprising only the first receive beam can not be able to guarantee the received signal quality of the terminal. By using the above technical solution, the possibility that the received signal quality cannot be guaranteed due to a possible change in the communication environment can be reduced to a certain extent by using a time trigger condition.

[0134] On the basis of the above two alternative embodiments, in an alternative embodiment of the present application, the method further comprises: the predefined time duration is set in a timer of the terminal, and when the timer expires, the above reconfiguration action is completed. In another alternative embodiment of the present application, the method further comprises: a discontinuous reception cycle timer is used, and when the discontinuous reception cycle timer expires N (N≥1) times, the above reconfiguration action is completed.

[0135] It should be understood that the timer in the embodiments of the present application can be a software timer, and setting the predefined time duration can be understood as setting the parameters corresponding to the software module of the related timing function of the software algorithm. The timer in the embodiments of the present application can also be a hardware circuit or device of the terminal, and setting the predefined time duration can be understood as setting the parameters of the hardware timing circuit or timer. The timer in the embodiments of the present application can also be completed by combining the related software module of the software algorithm and the above hardware circuit or device, for example, setting the timer parameters in the SoC chip to the time duration of the discontinuous reception cycle, and setting the counter to N in the related software module of the software algorithm. Each time the timer expires, the counter decreases by 1, and when the counter is cleared, it indicates that the predefined time duration has elapsed.

[0136] In an alternative embodiment, after updating the set of receive beams of the serving cell, the method further comprises:

[0137] S504c: reconfiguring the set of receive beams of the serving cell when the signal metric corresponding to the optimal receive beam is lower than the metric lower threshold, the reconfigured set of receive beams of the serving cell comprising the first receive beam and the second receive beam.

[0138] In an alternative embodiment, after updating the set of receive beams of the serving cell, the method further comprises:

[0139] S504d: reconfiguring the set of receive beams of the serving cell when the signal metric corresponding to the optimal receive beam is lower than the metric lower threshold, the reconfigured set of receive beams of the serving cell comprising the first receive beam and other receive beams.

[0140] It should be understood that the other receive beams can be the same as one or more of the second receive beams, or can be completely different from the second receive beams.

[0141] Further, optionally, the signal metric corresponding to the optimal receive beam comprises a reference signal received power (RSRP). Optionally, the signal metric corresponding to the optimal receive beam comprises a received signal strength indicator (RSSI). Optionally, the signal metric corresponding to the optimal receive beam comprises a reference signal received quantity (RSRQ). Optionally, the signal metric corresponding to the optimal receive beam comprises a signal to inference plus noise (SINR).

[0142] It should be understood that the above-mentioned signal metric can be a layer 1 measurement result based on a synchronization signal block measurement. Alternatively, the above-mentioned signal metric can be a layer 1 measurement result based on a channel state information reference signal (CSI-RS) measurement. It should be understood that the signal metric corresponding to the optimal receive beam can also comprise any combination of the above-mentioned alternative embodiments. Wherein, the layer 1 measurement result can also be understood as a physical layer measurement result.

[0143] It should be understood that when the signal metric corresponding to the updated set of receive beams does not meet the requirement of the terminal, the reconfiguration action is triggered, otherwise, the current updated set of receive beams is maintained. With the above technical solution, whether the signal metric corresponding to the updated set of receive beams meets the communication requirement of the terminal can be determined, and the reconfiguration action is triggered to ensure the quality of the received signal.

[0144] In an optional implementation, after the set of receive beams of the serving cell is updated, the method further comprises:

[0145] S504e: reconfiguring the set of receive beams of the serving cell according to the change of the motion state of the terminal, wherein the reconfigured set of receive beams of the serving cell comprises the first receive beam and the second receive beam.

[0146] S504f: reconfiguring the set of receive beams of the serving cell according to the change of the motion state of the terminal, wherein the reconfigured set of receive beams of the serving cell comprises the first receive beam and other receive beams.

[0147] Further, the method further comprises: obtaining the state information of the sensor of the terminal to determine the change of the motion state of the terminal.

[0148] It should be understood that the sensor of the terminal can monitor the motion state of the terminal and generate the motion state record of the terminal. The communication device can determine whether the motion state of the terminal changes by reading the motion record of the terminal from the sensor. For example, when the motion state record of the terminal exceeds a predefined range, it is determined that the motion state of the terminal changes. Alternatively, when the motion state record of the terminal changes, it is determined that the motion state of the terminal changes.

[0149] Alternatively, the sensor of the terminal can also determine whether the motion state of the terminal changes according to the monitored motion state record and generate a corresponding indication. For example, when the sensor of the terminal monitors that the motion state (such as speed) of the terminal changes beyond a predefined range, the sensor generates an indication bit with a value of 1, and the communication device determines that the motion state of the terminal changes by reading the indication bit.

[0150] With the above technical solution, whether the motion state of the terminal exceeds a predefined range can be determined, and the reconfiguration action is triggered to ensure the quality of the received signal.

[0151] It should be understood that any of the optional embodiments described above can be combined with each other. After updating the set of receive beams of the serving cell, the reconfiguration action can be triggered when any one or any two of the triggering conditions described above are met, reconfiguring the set of receive beams of the serving cell, the reconfigured set of receive beams of the serving cell including the first receive beam and the second receive beam. Alternatively, the reconfigured set of receive beams of the serving cell includes the first receive beam and other receive beams. With the above technical solutions, the triggering conditions can be reduced to further guarantee the received signal quality.

[0152] It should be understood that the updated set of receive beams of the serving cell can be used to receive the downlink message of the serving cell. Further, one or more receive beams in the updated set of receive beams of the serving cell can be used to receive the downlink message of the serving cell. Specifically, the communication device can configure the terminal to receive the downlink message of the serving cell through the receive beams described above. It should be understood that there are various embodiments of configuring the terminal to receive signals through a receive beam. The direction of the receive beam of the terminal can be the same as the receive beam by selecting the radio frequency transceiver circuit of the terminal. Alternatively, the parameters of the radio frequency transceiver circuit of the terminal can also be configured, such as the parameters of the phase shifter. Alternatively, the weights of the antenna elements used for calculation can also be configured.

[0153] Alternatively, one or more receive beams in the updated set of receive beams of the serving cell can be used to determine the optimal receive beam or receive beam tracking. Specifically, the terminal is configured to receive the reference signal of the serving cell through the receive beams described above, and the optimal receive beam is determined according to the measurement results corresponding to the respective reference signals.

[0154] Further, alternatively, after reconfiguring the set of receive beams of the serving cell, the method further includes: re-determining the optimal receive beam of the serving cell in the reconfigured set of receive beams of the serving cell.

[0155] It should be understood that after completing the reconfiguration action, receive beam tracking can also be re-performed in the reconfigured set of receive beams of the serving cell to guarantee the received signal quality of the serving cell. The above process can also be understood as a process that is executed in a loop.

[0156] Further, alternatively, the specific manner of determining the optimal receive beam of the serving cell in the set of receive beams of the serving cell of the terminal can include: determining the optimal receive beam of the serving cell once in the set of receive beams of the serving cell in one DRX cycle.

[0157] It should be understood that the optimal receiving beam of the serving cell can be determined once in the receiving beam set of the serving cell in one DRX cycle. The DRX cycle here can be a DRX short cycle or a DRX long cycle.

[0158] Optionally, the specific manner of determining the optimal receiving beam of the serving cell in the receiving beam set of the serving cell of the terminal can include: determining the optimal receiving beam of the serving cell once in the receiving beam set of the serving cell in a plurality of consecutive DRX cycles.

[0159] It should be understood that the optimal receiving beam of the serving cell can be determined once in the receiving beam set of the serving cell in one DRX cycle. The optimal receiving beam can be used in the next or several subsequent DRX cycles.

[0160] Further, optionally, the terminal can be in an idle state or a deactivated state, and the above-mentioned embodiments are performed based on the measurement result corresponding to the SSB-based measurement. The downlink message of the serving cell can include a paging message of the serving cell. Optionally, the terminal can be in a connected state, and the above-mentioned embodiments are performed based on the measurement result corresponding to the CSI-RS-based measurement. The downlink message of the serving cell can include downlink data (such as downlink channel information) of the serving cell.

[0161] Figure 6 A method flow diagram of beam management provided by an embodiment of the present application is shown. The method can be performed by a communication device, which can be a terminal or a chip that can be arranged in the terminal. The chip can be a baseband processor or an SoC chip. As shown in the figure, the method includes: Figure 6

[0162] S601: determining an optimal receiving beam of a serving cell in a receiving beam set of the serving cell of a terminal, wherein the receiving beam set of the serving cell includes a first receiving beam, a second receiving beam, and other receiving beams, and the second receiving beam is an adjacent receiving beam of the first receiving beam.

[0163] S602: receiving a downlink signal of the serving cell through the optimal receiving beam.

[0164] S603: when the first receiving beam is determined as the optimal receiving beam of the serving cell for a plurality of consecutive times, updating the receiving beam set of the serving cell of the terminal, and the updated receiving beam set of the serving cell only includes the first receiving beam and the second receiving beam.

[0165] ​It should be understood that the first receive beam can be one or more receive beams. The second receive beam can be one or more receive beams adjacent in direction or close in number to the first receive beam. When the first receive beam is determined as the optimal receive beam of the serving cell for multiple times in succession, the receive beams adjacent in direction or close in number to the first receive beam can also have relatively good receive signal quality. Therefore, the updated receive beam set can include the first receive beam and the receive beams adjacent in direction or close in number to the first receive beam. Here, the number can be understood as the number of transmit beams, for example, the first receive beam is receive beam 2, the second receive beam is receive beam 1 and receive beam 3. It can also be understood as the number of SSBs, for example, the first receive beam corresponds to SSB1 and SSB2, and the second receive beam corresponds to SSB3. It can also be understood as the number of codebooks, for example, the first receive beam can correspond to a receive beam formed by using codebook B, and the second receive beam can correspond to a receive beam formed by using codebook A and a receive beam formed by using codebook C.

[0166] Further, it can be understood that the communication device can receive the downlink signal of the serving cell through the first receive beam and the receive beams adjacent in direction or close in number to the first receive beam, and in the next period of time, the receive beam tracking can not be performed again, and the power consumption of the terminal can be reduced. It can also be understood that the communication device can perform receive beam tracking in the first receive beam and the receive beams adjacent in direction or close in number to the first receive beam, and determine the optimal receive beam, which can speed up the beam tracking while reducing the power consumption of the terminal.

[0167] Figure 7 A method flow diagram of beam management provided by an embodiment of the present application is provided. The method can be performed by a communication device, which can be a terminal or a chip that can be arranged in the terminal. The chip can be a baseband processor or an SoC chip. As shown in the figure, the method includes the following steps. Figure 7

[0168] S701: In a receive beam set of a serving cell of a terminal, an optimal receive beam of the serving cell is determined, wherein the receive beam set of the serving cell includes a first receive beam, a second receive beam and other receive beams.

[0169] S702: A downlink signal of the serving cell is received through the optimal receive beam.

[0170] S703: When the first receive beam and the second receive beam are respectively determined as the optimal receive beam of the serving cell within a first time length, the receive beam set of the serving cell of the terminal is updated, and the updated receive beam set of the serving cell only includes the first receive beam and the second receive beam.​

[0171] It should be understood that the first receiving beam can be one or more receiving beams, and the second receiving beam can be one or more receiving beams. When multiple receiving beams are determined as the optimal receiving beam of the serving cell multiple times within a certain time length, it can be assumed that the signal quality received by the multiple receiving beams is relatively guaranteed. Therefore, the updated receiving beam set can include the multiple receiving beams. For example, in the first, third, and fifth judgment processes within a certain time length, receiving beam 1 is determined as the optimal receiving beam in the receiving beam set of the serving cell, and in the second, fourth, and sixth judgment processes, receiving beam 3 is determined as the optimal receiving beam in the receiving beam set of the serving cell. At this time, it can be considered that the signal quality received by receiving beam 1 and receiving beam 3 is relatively guaranteed. Then, the updated receiving beam set can include the above-mentioned receiving beam 1 and receiving beam 3.

[0172] Further, it can be understood that the communication device can receive the downlink signal of the serving cell through the first receiving beam and the second receiving beam, and in the following period of time, the receiving beam tracking can not be performed again, and the power consumption of the terminal can be reduced. It can also be understood that the communication device can perform receiving beam tracking in the first receiving beam and the second receiving beam, and determine the optimal receiving beam therefrom, which can reduce the power consumption of the terminal while speeding up the beam tracking.

[0173] It should be understood that Figure 6 and Figure 7 The method shown in the above embodiments can also have various implementation manners, and the description of S504a to S504f and the related more specific implementation manners in the above embodiments can be referred to.

[0179] ​In addition, the apparatus 20 can further include a memory 240, a connection line 250, and an I / O interface. The memory 240 is configured to store computer programs or computer instructions.

However, for the purpose of clear illustration, all the buses are collectively referred to as a bus system in this paper.

[0180] It should be understood that when the memory 240 stores the function programs of the terminal-related communication device, the wireless communication apparatus 20 can be a terminal in the wireless communication system of the embodiments of the present application, or can be a chip or circuit that can be arranged in the terminal.

[0181] Figure 10 A structural schematic diagram of an apparatus provided by the embodiments of the present application is shown. The apparatus can be a terminal in the wireless communication system of the embodiments of the present application, or can be a chip or circuit that can be arranged in the terminal. The chip can be a baseband processor or an SoC chip, and can implement the beam management method as shown in Figures 5 to 7 , and each of the optional embodiments described above. In an exemplary design as shown in Figure 10 , the apparatus 30 includes an antenna module 310, a radio frequency (RF) subsystem 320 coupled with the antenna module 310, and a baseband subsystem 330 coupled with the RF subsystem 320.

[0182] In an optional implementation, the RF subsystem 320 is configured to determine an optimal reception beam of a serving cell in a reception beam set of the serving cell, wherein the reception beam set of the serving cell includes a first reception beam and a second reception beam; the antenna module 310 and the RF subsystem 320 are configured to receive a downlink message of the serving cell through the optimal reception beam; and the RF subsystem 320 is further configured to update the reception beam set of the serving cell when the first reception beam is determined as the optimal reception beam of the serving cell for a plurality of consecutive times, and the updated reception beam set of the serving cell only includes the first reception beam.

[0183] The antenna module 310 can be configured to receive a signal, and the signal is input to the radio frequency subsystem 320 in the form of a radio frequency signal corresponding to the signal. The radio frequency subsystem 320 can be configured to process (for example, filter, denoise, amplify, etc.) the received radio frequency signal, and down-convert the radio frequency signal to a baseband signal for processing by the baseband subsystem 330. The radio frequency subsystem 320 can include a radio frequency front-end module 321 and a radio frequency transceiver module 342. The baseband subsystem 330 can be configured to implement the beam management method as shown in Figures 5 to 7 and the optional embodiments described above based on measurement results based on the baseband signal corresponding to the received signal.

[0184] Figure 11 A structural schematic diagram of an apparatus according to an embodiment of the present application is shown. The apparatus is based on the apparatus shown in Figure 10 and further introduces some optional implementation manners of the embodiment of the present application. For details, refer to the description of Figure 10 . The repeated content will not be described here. In an exemplary design as shown in Figure 11 , the apparatus 40 includes an antenna module 410, a radio frequency subsystem 420 coupled to the antenna module 410, and a baseband subsystem 430 coupled to the radio frequency subsystem 420.

[0185] In addition, the apparatus 40 can further include a first memory 460 coupled to the baseband subsystem 430. The baseband subsystem 430 includes a processor 431 and a second memory 432. The first memory 460 is coupled to the second memory 432 in the baseband subsystem 430. The first memory 460 can be a non-volatile memory, and the second memory 432 can be a volatile memory or a non-volatile memory. Specifically, the volatile memory refers to a memory whose internal data will be lost when the power supply is interrupted. At present, the volatile memory mainly refers to a random access memory (RAM), including a static RAM and a dynamic RAM. The non-volatile memory refers to a memory whose internal data will not be lost when the power supply is interrupted. Common non-volatile memories include read-only memories, optical discs, magnetic discs, solid-state hard discs, and various memory cards based on flash memory technology, etc. Specifically, the first memory 460 can be used to store one or more instructions corresponding to the method provided by any embodiment of the present application. After the apparatus 40 is powered on, the code is loaded into the second memory 432 and executed by the processor 431. Referring to Figure 11 , the code can be used to implement the beam management method as shown inFigures 5 to 7 The processor 431 can further include a cache connected with the second memory 432, and the code in the second memory 432 can be cached in the cache to be executed by the processor.

[0186] In one possible implementation, the baseband subsystem 330 configures one or more parameters in the antenna module and the radio frequency receiving circuit, so that the terminal can sequentially receive synchronization signal blocks in a plurality of periodic synchronization signal burst sets through each receiving beam in a receiving beam set of a serving cell of the terminal, and determine an optimal receiving beam in the receiving beam set according to measurement results of the corresponding receiving beams. When the first receiving beam is determined as the optimal receiving beam of the serving cell for a plurality of times in succession, the receiving beam set of the serving cell is updated, and the updated receiving beam set of the serving cell only includes the first receiving beam.

[0187] It should be understood that, in the embodiments of the present application, the radio frequency receiving circuit can include one or more of the input circuit, the low-noise amplifier, and the receiving circuit, and can further include the radio frequency front-end module 421 and the antenna module 410. The radio frequency transmitting circuit can include one or more of the output circuit, the power amplifier, and the transmitting circuit, and can further include the radio frequency front-end module 421 and the antenna module 410. It should be understood that the antenna module 410 and part or all of the circuits in the radio frequency subsystem 420 can individually or collectively constitute the radio frequency receiving circuit 440 for receiving radio frequency signals.

[0188] It should be understood that there are various implementations for configuring a receiving beam in the receiving beam set. Alternatively, the baseband subsystem 430 selects a radio frequency receiving circuit 440 to receive signals through the receiving beam in the receiving beam set; alternatively, the baseband subsystem 430 adjusts the parameters of the radio frequency receiving circuit 440 to receive signals through the receiving beam in the receiving beam set.

[0189] It should be understood that the antenna module 410 receives the signal of the serving cell and inputs the corresponding radio frequency signal of the signal of the serving cell into the selected radio frequency receiving circuit, and then converts into a baseband signal for processing by the baseband subsystem 430. The following description is based on the assumption that one of the selected radio frequency receiving circuits is the radio frequency receiving circuit 440a, and the antenna module 410 receives the corresponding radio frequency signal of the signal of the serving cell, and inputs the radio frequency signal into the selected radio frequency receiving circuit 440a through the radio frequency front-end module 421 in the form of a radio frequency signal. The radio frequency front-end module 421 can include an antenna switch, a duplexer, a diplexer, etc. For the radio frequency signal from the radio frequency front-end module 421, the input circuit 441a in the radio frequency receiving circuit 440a is used for pre-processing (for example, filtering, etc.) to provide the low-noise amplifier 442a in the form of a radio frequency signal. The low-noise amplifier 442a amplifies the received signal with lower noise and inputs the radio frequency signal into the receiving circuit 443a. The receiving circuit 443a amplifies, filters, and down-converts the radio frequency signal from the low-noise amplifier 442a to a baseband signal for processing and judgment by the baseband subsystem. The baseband subsystem 430 measures, processes, and judges according to the received baseband signal.

[0190] On the basis of the above-mentioned optional implementation, in an optional implementation in the embodiment of the present application, the parameters of the radio frequency receiving circuit 440 include antenna array element weights for calculation. At this time, the corresponding operation can be performed in the digital domain by the baseband subsystem, and the analog part adopts a fixed connection network, one antenna array element is connected with one corresponding radio frequency chain (RF chain). The flexibility of the device is relatively high, and can be used for digital beamforming.

[0191] On the basis of the above-mentioned optional implementation, in an optional implementation in the embodiment of the present application, the parameters of the radio frequency receiving circuit 440 include phaser shift parameters, such as the weights of the phasers. At this time, the corresponding operation is implemented in the analog domain, and the implementation of the device is simple, and the cost and power consumption are relatively low, which can be used for analog beamforming.

[0192] On the basis of the above-mentioned optional implementation, in an optional implementation in the embodiment of the present application, the parameters of the radio frequency receiving circuit 440 include antenna array element weights and phaser parameters for calculation, such as the weights of the antenna array elements and the weights of the phasers. The device has good flexibility and low cost, and can be used for hybrid beamforming.

[0193] It should be understood that the parts of the devices in the embodiments of the present application can be integrated into one chip or integrated circuit, or can be combined into different chips or circuits accordingly, or can be combined into a whole machine (for example, a terminal, a base station, etc.), which all belong to the protection scope of the embodiments of the present application. It should be understood that in the embodiments of the present application, the radio frequency transceiver module 342 can also be a radio frequency receiving module or a radio frequency receiving module, which can be integrated with the baseband subsystem 330 or / and the antenna module 310, or can be arranged separately from the baseband subsystem 330 or / and the antenna module 310.

[0194] In order to introduce the technical solutions of the embodiments of the present application in more detail, the present application also provides the following optional embodiments. Among them, embodiments 1 and 2 mainly introduce several possible specific implementation manners and specific implementation processes of using the present application scheme for the serving cell, and embodiment 3 mainly introduces several possible exemplary designs of using the present application scheme device.

[0195] Embodiment 1

[0196] The embodiments of the present application will be illustrated for the serving cell.

[0197] The wireless network device periodically transmits a synchronization signal burst set, and each synchronization signal burst set needs to be transmitted within a window range of 5 milliseconds (ms). For example, referring to Figure 3 , a synchronization signal burst set can include two different SSBs, denoted as SSB1 and SSB2. It should be understood that the SSBs here can be understood as different in time domain and the same in power domain. SSB1 and SSB2 can be transmitted by the wireless network device corresponding to the serving cell through transmit beam 1 and transmit beam 2 in different time slots in turn.

[0198] In order to determine the optimal receiving beam of the serving cell, the terminal in the idle state or the deactivated state will receive and measure the above SSBs. Assuming that the currently available receiving beams are receiving beam a, receiving beam b and receiving beam c, which can be used to receive SSB1 and SSB2 from the serving cell.

[0199] The set of configured receive beams Φ including receive beam a, receive beam b and receive beam c, denoted as Φ = {a, b, c}, can be used to receive SSB1 and SSB2 from the serving cell, and the optimal receive beam of the serving cell is determined according to the corresponding measurement results. Specifically, in a round of measurement process, the configured receive beam a receives SSB1 and SSB2 in turn in the first synchronization signal burst set transmission period; the configured receive beam b receives SSB1 and SSB2 in turn in the second synchronization signal burst set transmission period; and the configured receive beam c receives SSB1 and SSB2 in turn in the third synchronization signal burst set. By measuring SSB1 and SSB2 received by receive beam a, receive beam b and receive beam c respectively, the measurement results corresponding to different beam pair links can be obtained, and the optimal receive beam and the optimal beam pair link can be determined according to the above measurement results. Here, the measurement results can include RSRP, unit: decibel milliwatt (dBm). For ease of description, the above process is denoted as a round of measurement, corresponding to one measurement scheduling period.

[0200] Table 1 gives an example of a set of measurement results, where i represents the ith round of measurement. For the ith round of measurement, transmit beam 1 and receive beam a form beam pair link 1a, and the corresponding measurement result is denoted as Transmit beam 2 and receive beam a form beam pair link 2a, and the corresponding measurement result is denoted as Other combinations are similar.

[0201] In order to reduce the power consumption of terminal measurement, under certain conditions, the set of configured receive beams only includes the optimal receive beam determined by the measurement results for a plurality of times in succession, and the set of receive beams can be used to receive signals of the serving cell. In this way, the number of measurements or the length of each round of measurement is reduced, thereby reducing the power consumption.

[0202] For example, an entering threshold condition is introduced. When the optimal receive beam determined according to the measurement results corresponding to the consecutive multiple rounds of measurement remains unchanged, it can be assumed that the communication environment of the terminal remains unchanged or the change of the communication environment of the terminal can be ignored. Therefore, the configured receive beam set only includes the optimal receive beam determined according to the measurement results, and the receive beam set can be used to receive the signal of the serving cell. The measurement round of the entering threshold condition can be predefined. Here, it is assumed that the predefined consecutive measurement times are 3 rounds. Referring to Table 1, for the first round of measurement, the measurement result RSRP corresponding to the beam pair link 1a has the maximum value of -70 dBm. It is determined that the beam pair link 1a is the optimal beam pair link, and the corresponding receive beam a is the optimal receive beam. Similarly, according to the second round and the third round of measurement results, it is determined that the receive beam a is the optimal receive beam. Therefore, the configured receive beam set Φ' only includes the receive beam a, denoted as Φ' = {a}, and the receive beam set Φ' can be used to receive one or more of the SSB of the serving cell and the paging message of the serving cell. It should be understood that the entering threshold condition here can also be that the optimal receive beam determined according to the measurement results corresponding to a period of time remains unchanged. Here, the value of the period of time can be predefined or calculated according to the number of consecutive rounds of measurement and the period of each round of measurement.

[0203] After the configured receive beam set Φ' is used to receive the signal for a period of time, the communication environment can change, and the optimal communication quality cannot be obtained by continuing to use the configured receive beam set Φ'. Therefore, an exiting mechanism can be designed. When the exiting condition is met, the receive beam set Φ = {a, b, c} is reconfigured to receive the SSB of the serving cell to enter the next round of measurement scheduling to determine the optimal receive beam of the serving cell. Otherwise, the configuration of the current receive beam set is maintained.

[0204] For example, a time exiting mechanism is designed. It is assumed that the predefined scheduling time threshold is 10 seconds (s). After the receive beam set is configured to receive the SSB of the serving cell or the paging signal of the serving cell for 10 s, the receive beam set Φ = {a, b, c} is reconfigured to enter a new round of measurement scheduling.

[0205] It should be understood that the time exiting mechanism can also be a counting exiting mechanism. It is assumed that the predefined scheduling round threshold is 10 times. After the receive beam set Φ' is configured to receive the SSB of the serving cell or the paging signal of the serving cell for 10 times, the receive beam set Φ = {a, b, c} is reconfigured to enter a new round of measurement scheduling to determine the optimal receive beam of the serving cell. The time threshold and the scheduling round threshold can be converted according to the measurement scheduling period.

[0206] For example, a motion state monitoring exit mechanism is designed. When the motion state of the terminal is monitored to change, the receiving beam set Φ = {a, b, c} is reconfigured to receive the SSB of the serving cell to enter a new round of measurement scheduling, and the optimal receiving beam of the serving cell is determined.

[0207] It should be understood that the trigger conditions in each of the above exit mechanisms can be combined with each other. When any one or more of the trigger conditions are met, the above reconfiguration action is performed. By using the above scheme provided in the embodiments of the present application, the number of measurements and the length of each round of measurement can be effectively reduced, the power consumption can be reduced, and the standby time can be improved.

[0208] Table 1 measurement result example

[0209]

[0210] In order to further guarantee the reliability of the measurement scheduling in the above scheme, the entry condition can also be improved. For example, a threshold judgment mechanism is introduced, the value of the upper threshold Γ1 is predefined, and only when the measurement result corresponding to the optimal receiving beam determined by the continuous multiple measurement results is greater than the predefined upper threshold Γ1, the receiving beam set is configured to only include the optimal receiving beam determined by the continuous multiple measurement results, and the receiving beam set can be used to receive the signal of the serving cell.

[0211] Table 2 gives a group of measurement result examples, assuming that the value of the predefined upper threshold Γ1 is -80dBm. According to the measurement from the forty-fifth round to the forty-seventh round, it is determined that the beam pair link of each round is 2a, 1a, 1a in turn, and the optimal receiving beam is receiving beam a. And according to the measurement result, for the above three consecutive measurements, the measurement results corresponding to the beam pair link of receiving beam a are all greater than -80dBm. Therefore, the receiving beam set Φ' is configured to only include receiving beam a, denoted as Φ' = {a}, and the receiving beam set Φ' can be used to receive one or more of the SSB of the serving cell and the paging message of the serving cell.

[0212] Similarly, after the receiving beam set Φ' is configured to receive the SSB or the paging message of the serving cell, even if a time exit mechanism or a number exit mechanism is designed, when the scheduling does not reach the scheduling duration threshold or the scheduling round threshold, the configured receiving beam set Φ' may not be able to obtain the optimal communication quality due to changes in the communication environment. Therefore, in order to further guarantee the reliability of the measurement scheduling in the above scheme, the exit condition can also be reduced.

[0213] For example, a exit threshold determination mechanism is introduced, and a value of the lower threshold Γ2 is predefined. For the optimal receive beam in the configured receive beam set Φ' determined by the measurement results of previous rounds, when the measurement results corresponding to all beam pair links of the receive beam are less than the predefined lower threshold Γ2 for consecutive multiple times, the receive beam set Φ = {a, b, c} is reconfigured to receive the SSB of the serving cell to enter a new round of measurement scheduling to determine the optimal receive beam of the serving cell.

[0214] The value of the predefined lower threshold Γ2 is-95dBm, and see Table 2. After the receive beam Φ' is configured to receive the SSB of the serving cell, the SSB1 and SSB2 received by the receive beam a are measured. According to the measurement results, for the fifty-third to fifty-fifth round of measurement, it is determined that the measurement results corresponding to all beam pair links of the receive beam a are less than-95dBm, and therefore, the receive beam set Φ = {a, b, c} is reconfigured to receive the SSB of the serving cell to enter a new round of measurement scheduling to determine the optimal receive beam of the serving cell.

[0215] It should be understood that the trigger conditions in each of the above exit mechanisms can be combined with each other, and when any one or more of the trigger conditions are met, the above reconfiguration action is performed. By using the scheme provided in the embodiments of the present application, the number of measurements and the length of each round of measurement can be effectively reduced on the basis of ensuring the reliability of the measurement results, the power consumption is reduced, and the standby time is improved.

[0216] Table 2 measurement result example

[0217]

[0218] Embodiment 2

[0219] It should be understood that the repeated parts of the embodiments of the present application are based on the basis of embodiment 1, and the description can be referred to in embodiment 1, which will not be repeated here.

[0220] When the measurement results corresponding to the optimal receive beam and the suboptimal receive beam have a small difference in value, the suboptimal receive beam determined this time may correspond to a measurement result in the next round of measurement due to the measurement result corresponding to the optimal receive beam determined this time. In order to obtain better communication quality, the receive beam set can no longer be configured with the receive beam with poor communication quality to reduce the number of measurements or the length of each round of measurement.

[0221] For example, an entering threshold condition is introduced. When the worst receive beam determined according to the measurement results corresponding to the consecutive multiple rounds of measurement remains unchanged, it can be considered that the communication environment of the terminal remains unchanged or the change of the communication environment of the terminal can be ignored. In this case, the receive beam set configured only includes the receive beams other than the worst receive beam determined according to the measurement results, and the receive beam set can be used to receive signals. The worst receive beam can be the receive beam corresponding to the worst communication quality, or can be the receive beam corresponding to the measurement result less than the predefined lower threshold Γ3.

[0222] The measurement round of the entering threshold condition can be predefined. Here, it is assumed that the predefined consecutive measurement times are 3 rounds. Table 3 gives an example of a set of measurement results. For the first round of measurement, the measurement results corresponding to beam pair link 3b and beam pair link 4b are -100 dBm and -98 dBm respectively, both of which are less than -95 dBm. Therefore, it is determined that the quality of the SSB received through the receive beam b is poor. Similarly, according to the second and third round of measurement results, it is determined that the quality of the SSB received through the receive beam b is poor, and the corresponding measurement results are both less than the threshold -90 dBm. Therefore, the receive beam set Φ' configured only includes the receive beams a and c, denoted as Φ' = {a, c}, to receive the SSB of the serving cell to enter a new round of measurement scheduling to determine the optimal receive beam of the serving cell. After a period of time, the communication environment may change, and the optimal communication quality cannot be obtained by using the configured receive beam set Φ' all the time. Therefore, a similar embodiment 1, an exiting mechanism, can be designed. When the exiting condition is met, the receive beam set Φ = {a, b, c} is reconfigured to receive the SSB of the serving cell to enter the next round of measurement scheduling to determine the optimal receive beam of the serving cell. Otherwise, the configuration of the current receive beam set is maintained.

[0223] By using the above scheme provided in the embodiments of the present application, the number of measurements and the time length of each round of measurement can be effectively reduced, the power consumption can be reduced, and the standby time length can be improved. It should be understood that the extension of other entering conditions and exiting conditions can refer to the description in embodiment 1, which will not be repeated here.

[0224] It should be understood that the optimal receive beam described above can also be used to receive the paging message of the same frequency neighbor cell or the different frequency neighbor cell. It should be understood that the schemes described in embodiments 1 and 2 are also applicable to the same frequency neighbor cell or the different frequency neighbor cell. For example, the receive beam set is configured to receive the SSB of the same frequency neighbor cell. When the optimal receive beam determined according to the measurement results corresponding to the consecutive multiple rounds of measurement remains unchanged, the receive beam set configured only includes the optimal receive beam determined according to the measurement results, and the receive beam set can be used to receive signals of the same frequency neighbor cell. The remaining cases can refer to the description in embodiments 1 and 2, which will not be repeated here.

[0228] Example 3

[0229] This application will use Embodiment 1 as an example to illustrate a serving cell, providing an exemplary device design employing the solution of this application. The structural design of this device can be referenced from the above description. Figures 8 to 11 The description will not be repeated here. For the sake of simplicity and ease of understanding, the following will use... Figure 11 The following is an example design scheme using the device in the example.

[0230] The wireless network equipment corresponding to the serving cell periodically transmits synchronization signal burst sets, and each synchronization signal burst set may include two different SSBs, denoted as SSB1 and SSB2 respectively. SSB1 and SSB2 can be transmitted sequentially by the wireless network equipment corresponding to the serving cell through transmit beam 1 and transmit beam 2 in different time slots.

[0231] See Figure 11 The illustrated device 40, assuming currently configurable receive beams a, b, and c, can be used to receive SSB1 and SSB2 from the wireless network device. To obtain better communication quality, the wireless network device 40 configures a set of receive beams to determine the optimal receive beam for the serving cell. The baseband subsystem 430 configures a set of receive beams Φ, including receive beams a, b, and c, denoted as Φ = {a, b, c}, to receive the SSBs of the serving cell and determine the optimal receive beam for the serving cell. Specifically, the baseband subsystem 430 can adjust the RF receiving circuit parameters or select one or more corresponding RF receiving circuits to configure the receive beam set to receive the SSBs of the serving cell.

[0232] For example, in a synchronization signal burst set transmission period, the baseband subsystem 430 can adjust the receive beam direction to the direction of the receive beam a by adjusting the phase shifter parameters (e.g., phase shifter weights) in the radio frequency subsystem, and receive SSB1 and SSB2 from the wireless network device through the antenna module 410. The radio frequency signal received by the antenna module 410 is sent into the radio frequency subsystem 420, and the radio frequency subsystem 420 performs filtering, noise reduction, amplification, etc. on the received signal, and down-converts the radio frequency signal to a baseband signal for processing by the baseband subsystem 430. The baseband subsystem 430 performs measurement, calculation, etc. on the received signal, and obtains corresponding calculation results. In the next two synchronization signal burst set transmission periods, the receive beam b and the receive beam c are configured in turn to receive SSB1 and SSB2 from the wireless network device, and the specific implementation is the same as the configuration of the receive beam a. Here, the measurement results include RSRP, with units of decibel-milliwatts (dBm). The corresponding calculation results can be stored in the second memory 432 in the baseband subsystem 430. In the embodiments of the present application, various tables can also be implemented using other data structures, such as arrays, queues, containers, stacks, linear tables, pointers, linked lists, trees, graphs, structures, classes, heaps, hash tables, etc.

[0233] Referring to the measurement results shown in Table 1, for the first round of measurement, the baseband subsystem 430 determines that the measurement result RSRP corresponding to the beam pair link 1a has the maximum value and is greater than the predefined upper threshold Γ1-80 dBm. It is determined that the beam pair link 1a is the optimal beam pair link, and the corresponding receive beam a is the optimal receive beam. Similarly, according to the second round and the third round of measurement results, the baseband subsystem 430 determines that the receive beam a is the optimal receive beam.

[0234] Therefore, the baseband subsystem 430 configures the receive beam set Φ' to include only the receive beam a, denoted as Φ' = {a}, for receiving the SSB of the serving cell.

[0235] The timer in the baseband subsystem 430 can be used to calculate whether the predefined scheduling duration threshold is currently reached. When the predefined scheduling duration threshold is reached, the receive beam set Φ = {a, b, c} is reconfigured to receive the SSB of the serving cell to enter a new round of measurement scheduling, and the optimal receive beam of the serving cell is determined.

[0236] Alternatively, the counter in the baseband subsystem 430 can also be used to calculate whether the predefined scheduling round threshold is currently reached. When the predefined scheduling round threshold is reached, the receive beam set Φ = {a, b, c} is reconfigured to receive the SSB of the serving cell to enter a new round of measurement scheduling, and the optimal receive beam of the serving cell is determined.

[0237] Or, the motion state of the current device 40 can also be monitored by the sensor of the device 40 and sent to the baseband subsystem 430. When the baseband subsystem determines that the motion state of the current device 40 changes, the receiving beam set Φ = {a, b, c} is reconfigured to receive the SSB of the serving cell into a new round of measurement scheduling to determine the optimal receiving beam of the serving cell.

[0238] Or, the baseband subsystem 430 can also determine that the continuous multiple measurement results corresponding to the current receiving beam a are all less than the pre-defined lower threshold Γ2, reconfigure the receiving beam set Φ = {a, b, c} to receive the SSB of the serving cell into a new round of measurement scheduling to determine the optimal receiving beam of the serving cell.

[0239] It should be understood that there are other different implementations of the method of configuring the receiving beam set.

[0240] Optionally, the baseband subsystem 430 adjusts the antenna array element weight used for calculation to adjust the receiving beam direction. The device design method using this implementation has higher degree of freedom.

[0241] Optionally, the baseband subsystem 430 adjusts the antenna array element weight used for calculation and the phase shifter parameter (for example, the phase shifter weight) in the radio frequency subsystem 420 to adjust the receiving beam direction. The device design method using this implementation can reduce the structure complexity while reducing the number of phase shifters, reducing the cost and improving the degree of freedom.

[0242] Or, the baseband subsystem 430 selects one or more radio frequency channels to adjust the receiving beam direction. The device design method using this implementation can reduce the structure complexity while reducing the number of phase shifters, reducing the cost and improving the degree of freedom.

[0243] The device provided by the above embodiments of the present application can effectively reduce the number of measurements and the length of each round of measurement, reduce power consumption, and improve standby time. Optionally, the receiving beam direction is adjusted by adjusting the phase shifter parameter, which is simple to implement and has relatively low cost and power consumption; optionally, the receiving beam direction is adjusted by adjusting the antenna array element weight, which has higher degree of freedom; optionally, the receiving beam direction is adjusted by adjusting the phase shifter parameter and the communication array element weight, which can reduce the structure complexity while reducing the number of phase shifters, reducing the cost and improving the degree of freedom.
