Abstract

The application provides an information receiving method and device. A User Equipment (UE) acquires a beam receiving mode before entering a sleep mode, and acquires different device posture information corresponding to different beam receiving modes in the sleep mode. And the UE determines a time window for receiving the paging information in the paging time according to the displacement or attitude change amplitude of the UE during the sleep period reflected by the equipment attitude information, and awakens and receives the paging information only in the determined specific time window. Thus, the UE may not need to wake up for beam training before each paging occasion and may not need to remain awake for each full paging occasion. By doing so, while the link robustness of the UE and the network device is ensured, the wake-up time of the UE is reduced, and the power consumption of the UE in a Discontinuous Reception (DRX) mode is further reduced.

Description

Information receiving method and device

Technical Field

The present application relates to the field of wireless communication technologies, and in particular, to an information receiving method and apparatus.

Background

In a high-frequency wireless communication scenario, for example, in the FR2 frequency band (millimeter wave frequency band, the frequency spectrum coverage range is from 24.25GHz to 52.6GHz) of the New Radio (NR) of the fifth generation (5G) cellular communication technology, an electromagnetic signal may experience a severe path loss during propagation, resulting in a severe attenuation of the strength of a received signal. To overcome this problem, network equipment and User Equipment (UE) may employ beamforming (beamforming) techniques to improve the directionality of signal transmission and reception. Accordingly, a physical layer communication link is established through beam training by the network device and the UE side to produce an optimal transmit-receive beam pair.

After the UE accesses the cell, if data transmission does not occur for a long time, the network device may configure the UE to enter a Discontinuous Reception (DRX) mode, so as to reduce power consumption. In DRX mode, the UE periodically wakes up from a sleep state when each Paging Occasion (PO) configured by the network device arrives, and monitors paging information. In particular, if the UE is paged, the UE then initiates random access to the network device; if the UE is not paged, the UE returns to the dormant state after the paging occasion is finished. Since the position and posture of the UE during sleep may change, the transmit-receive beam pairs determined by beam training by the UE and the network device before going to sleep may fail accordingly. To ensure that the UE can successfully receive paging information at the next paging occasion, conventional solutions require the UE to wake up for a complete beam training before each paging occasion comes to re-determine the matching transmit-receive beam pair. In addition, to improve link robustness, the UE may remain awake for the entire paging occasion. These approaches undoubtedly increase the wake-up time of the UE, resulting in additional power consumption overhead.

Disclosure of Invention

The application provides an information receiving method and device, which can reduce power consumption of UE in a DRX mode while ensuring robustness of a communication link between the UE and network equipment.

In a first aspect, the present application provides an information receiving method. The method comprises the following steps: the method comprises the steps that a beam receiving mode before the user equipment UE enters a Discontinuous Reception (DRX) mode is determined, wherein the beam receiving mode comprises omnidirectional reception and/or directional reception; the method comprises the steps that UE obtains equipment attitude information according to a beam receiving mode in a dormant state of a DRX mode, wherein the equipment attitude information comprises a displacement value and/or an attitude change value of the UE; the UE determines an awakening time window according to the equipment attitude information, wherein the time window is positioned in a paging timer of the network equipment; the UE wakes up in the time window and monitors the paging information of the network equipment.

According to the method provided by the application, the UE determines the time window for receiving the paging information in the paging time machine according to the equipment attitude information, and only wakes up and receives the paging information in the determined specific time window, the UE does not need to wake up to perform beam training before each paging occasion comes, and does not need to keep waking up in each complete paging time machine, so that the link robustness of the UE and the network equipment is ensured, meanwhile, the wake-up time of the UE is reduced, and the power consumption of the UE in a DRX mode is reduced.

In an alternative embodiment, when the beam receiving mode is omni-directional receiving, the device attitude information includes displacement values; when the displacement value is smaller than a preset first threshold value, the UE determines a time window as a time slot corresponding to the optimal transmitting beams of the X network devices in the paging occasion, and the optimal transmitting beams of the X network devices are determined by the UE and the network devices according to beam training and directional transmitting beams of the network devices; when the displacement value is greater than or equal to the first threshold, the UE determines the time window as the paging occasion. Therefore, when the UE adopts the omnidirectional receiving, the UE can obtain the displacement value of the UE in the DRX mode dormant state, and adaptively determines the time window for the UE to wake up in the paging machine according to the displacement value, so that the link robustness of the UE and the network equipment is ensured, the wake-up time of the UE is reduced, and the power consumption of the UE in the DRX mode is reduced.

In an alternative embodiment, when the beam receiving mode is directional receiving, the device attitude information includes displacement values and attitude change values; when the displacement value is smaller than a preset first threshold value and the attitude change value is smaller than a preset second threshold value, the UE determines a time window as a corresponding time slot of X optimal beam pair links in a paging occasion, wherein the X optimal beam pair links are determined by the UE and the network equipment according to beam training and a beam pair link between the network equipment and the UE; and when the displacement value is greater than or equal to a first threshold value or the attitude change value is greater than or equal to a second threshold value, the UE determines the time window as the paging occasion. Therefore, when the UE adopts directional reception, the UE obtains a displacement value or an attitude change value of the UE in a DRX mode dormant state, and adaptively determines a time window for awakening the UE in a paging machine according to the displacement value or the attitude change value, so that the awakening time of the UE is reduced and the power consumption of the UE in the DRX mode is reduced while the link robustness of the UE and the network equipment is ensured.

In an alternative embodiment, when the displacement value is greater than or equal to the first threshold, the UE maintains a listening state in the paging timer, and re-determines the X optimal transmission beams of the network device from the transmission beams of the network device. Therefore, when the next paging occasion comes, if the displacement value of the UE in the dormancy period between two paging occasions is smaller than the displacement threshold value, the UE can wake up in the corresponding time slot in the next paging occasion according to the redetermined optimal transmission beam of the network equipment.

In an alternative embodiment, when the displacement value is greater than or equal to the first threshold or the posture change value is greater than or equal to the second threshold, the UE wakes up before the paging occasion comes and determines X optimal beam pair links again. Therefore, when the position or the posture of the UE is changed remarkably, the UE wakes up in advance to perform beam training so as to re-determine X optimal beam pair links, so that the UE can wake up and monitor paging information according to the corresponding time slot of the re-determined optimal beam pair link in the paging occasion in the next paging occasion.

In an alternative embodiment, when the UE does not receive paging information within K consecutive paging occasions, the UE determines that the awake time window is the K +1 th paging occasion. Therefore, when the beam receiving mode is omni-directional receiving, if the UE does not successfully receive the paging information in the continuous K paging occasions, the UE can keep waking up and monitor the paging information at the K +1 th paging occasion, and simultaneously determines the optimal transmitting beam of the X network devices again so as to improve the probability of successful receiving of the paging information.

In an alternative embodiment, when the UE does not receive paging information in K consecutive paging occasions, the UE wakes up before the K +1 th paging occasion arrives, re-determines X optimal beam pair links, and determines a time window for waking up as a corresponding time slot of the re-determined X optimal beam pair links in the K +1 th paging occasion. Therefore, when the beam receiving mode is directional receiving, if the UE does not receive the paging information in the continuous K paging occasions, the UE can determine the time window for the UE to wake up in the K +1 th paging occasion according to the time slot corresponding to the X optimal beam pair link with the redetermined quota.

In an alternative embodiment, the displacement value or the attitude change value is determined according to one or more of acceleration sensor data, gyroscope data, geomagnetic sensor data, and gravity sensor data acquired by the UE in a sleep state.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. In the description of the embodiments of the present application, "/" indicates an alternative meaning unless otherwise specified, for example, a/B may indicate a or B; in the embodiment of the present application, "or" is only a relationship describing an associated object, and means that there may be three cases, that is, a or (or) B may mean that a exists alone, B exists alone, and a and B exist at the same time. In addition, in the description of the embodiments of the present application, "a plurality" means two or more.

Before explaining the technical solution of the embodiment of the present application, first, a technical background and an application scenario related to the technical solution of the embodiment of the present application are specifically explained.

With the popularization of high-definition streaming media playing, augmented reality and virtual reality applications, users put higher demands on the speed of mobile cellular communication. Since the achievable spectral efficiency of the prior art approaches shannon channel capacity (shannon capacity), high-rate transmission often needs to rely on wideband spectral resources. In view of the scarcity of microwave frequency bands, the third generation partnership project (3 GPP) has incorporated millimeter wave bands with abundant spectrum resources into the fifth generation (5G) cellular communication system standard to meet the demand of high-rate communications of users.

In a high-frequency wireless communication scenario, for example, in FR2 frequency band (millimeter wave frequency band, spectrum coverage range is from 24.25GHz to 52.6GHz) of new air interface (NR) of fifth generation cellular communication technology, electromagnetic signals generate serious path loss during propagation, thereby causing serious attenuation of received signal strength. To overcome this problem, network equipment and User Equipment (UE) may use beamforming (beamforming) techniques to improve the directionality of signal transmission and reception. The beam forming is realized by configuring a multi-antenna array at the network equipment and the UE side and setting corresponding antenna gain and phase parameters. Due to the limited coverage of each beam, the transmit beam of the network device and the receive beam of the UE must be efficiently paired to meet the link budget required for communication, for which beam training is an indispensable step to establish and maintain a beam pair that meets the link budget requirements. In the 5G NR protocol, a user equipment UE measures signal strength of a reference signal Synchronization Signal Block (SSB) and a channel state information-reference signal (CSI-RS), and performs beam scanning on a transmission beam of a network device by using two stages of wide and narrow reception beams in sequence, thereby finding a matching beam pair close to an optimal network device and UE.

After the UE accesses the cell, if the UE in the connected state has not transmitted data for a long time, the network device may configure the UE to enter the DRX mode to reduce power consumption.

Fig. 1 is a schematic diagram of communication between a UE and a network device in a DEX mode. As shown in fig. 1, in the DRX mode, the network device keeps tracking area (tracking area) information where the UE is located, and the UE enters a discontinuous reception state where the UE periodically switches between an awake state and a sleep state, where each switching period includes a paging occasion and a sleep occasion. Generally, the UE wakes up during paging and remains dormant during sleep.

In order to ensure that the paging information of the network device can reach the UE, the network device sends the same paging Downlink Control Information (DCI) and paging information in all cells included in the tracking area in a beam scanning manner at each Paging Occasion (PO). Correspondingly, the UE wakes up periodically at each paging occasion, monitors a paging DCI on a Physical Downlink Control Channel (PDCCH) by using a receive beam, and demodulates paging information on a Physical Downlink Shared Channel (PDSCH) according to the paging DCI. If the UE monitors the paging information, the UE initiates random access to the network equipment, and if the UE does not monitor the paging information, the UE continues to enter a dormant state after the paging occasion is ended. Since the position and posture of the UE during the sleep period may change, and the transmit-receive beam pair determined by the UE and the network device through the beam training may fail, the UE needs to wake up in advance to perform the beam training in order to ensure that the UE can successfully decode the paging DCI on the PDCCH and the corresponding paging information on the PDSCH when waking up at the next paging occasion. In conventional solutions, the UE needs to wake up in advance for a complete beam training before each paging occasion comes to re-determine the matched transmit-receive beam pair, which, while ensuring the effectiveness of the beam pair link, increases the UE wake-up time and causes additional power consumption overhead, which is highly unnecessary if the UE is not paged within the paging occasion. In addition, in the conventional solution, in order to improve the robustness of the link, the UE may remain awake during the integrated paging occasion, which also causes the power consumption overhead of the UE to be too large, and since the coverage of the UE and the beam of the network device on the link is limited, if the power consumption is reduced by reducing the UE awake time, the UE may not receive the paging information of the network device, thereby reducing the robustness of the link.

In order to solve the above problem, the present application provides an information receiving method, which can be applied to a scenario where a UE and a network device need to communicate through a beamforming technology, such as a 5G NR high frequency (e.g., FR2 frequency band) communication system.

The following is a first embodiment of an information receiving method provided by the present application, which is suitable for a scenario in which a UE employs an omni-directional receiving beam and a network device employs a directional transmitting beam. Fig. 4 is a flowchart of a first embodiment of an information receiving method provided in the present application. As shown in fig. 4, when the UE employs an omni-directional reception beam, the method may include the steps of:

step S101, when UE initially accesses to a cell, the UE measures the transmission beam of the network device by adopting the omnidirectional receiving beam so as to determine the optimal transmission beam of X network devices. Illustratively, the X network device optimal transmit beams may be the X highest gain transmit beams.

There are various ways to determine the optimal transmission beam, for example, the UE may determine the optimal transmission beam through beam training.

Fig. 5 is a diagram illustrating a UE determining an optimal transmission beam through beam training. As shown in fig. 5, assuming that the network device has 16 transmission beams in total and sequentially marked as 1, 2, …, and 16 according to the scanning order, in one beam scanning period, the network device sequentially uses the beams 1, 2, …, and 16 to transmit Synchronization Signal Block (SSB) information in a time-sharing scanning manner, and the UE sequentially receives the SSB information on all 16 transmission beams by using an omnidirectional reception beam, and determines X transmission beams with the highest gain as the optimal transmission beams of the network device based on the measurement result of Secondary Synchronization Signals (SSS) therein. For example, when X is 4, if the above 16 transmission beams are beams 7, 8, 6, 9, 5, and 10 … … in order of gain from high to low, the 4 optimal transmission beams that the UE can determine may be beams 6, 7, 8, and 9.

Step S102, when the UE enters a dormant state of an idle state DRX mode or a non-active state DRX mode, the UE acquires the posture information of the UE.

According to a Radio Resource Control (RRC) connected state before the UE enters the DRX mode, the network device may configure the UE with a corresponding DRX mode, as shown in the following table:

in scenarios where the UE employs an omni-directional receive beam, the device attitude information may include a displacement value Z generated by the UE during sleep in DRX mode. The displacement value Z may be measured from one or more sensors of the UE itself, for example, from data measured by an acceleration sensor during sleep of the UE.

Step S103, when the paging occasion comes, the UE according to the displacement value Z and the preset displacement threshold value Z₀The value relationship between the UE and the paging time, and the time window for the UE to wake up in the paging time is determined.

In a specific implementation, if the displacement value Z of the UE is smaller than the displacement threshold value Z₀Then, the time window for UE wake-up is the corresponding time slot of the optimal transmit beam of X network devices determined before the UE enters the sleep state in the paging timer. In the paging time machine, the UE wakes up only in the time slot corresponding to the X optimal transmission beams, and monitors and decodes the paging information of the network equipment by using the omnidirectional beams. If the paging is carried out, the UE initiates Random Access (RA) to the network equipment; otherwise, the UE continues to enter the sleep state beyond the time slots of the X optimal transmission beams.

Illustratively, as shown in fig. 6, if the UE is at the paging occasion T_n+0The previously determined optimal transmission beams of the network device are beams 6, 7, 8 and 9, and then when the displacement value Z of the UE is smaller than the displacement threshold value Z₀Then, the UE will be at the paging occasion T_n+0The time slots corresponding to the inner beams 6, 7, 8 and 9 are awakened, the paging information of the beams 6, 7, 8 and 9 is received and decoded, and if the paging information is paged, the UE initiates random access; if the UE does not receive paging information from beams 6, 7, 8 and 9, the UE will go to sleep earlier as shown in fig. 6. At the next paging occasion T_n+1When coming, if the UE is from the time of determining the optimal transmission beam of the network equipment to the next paging occasion T_n+1The accumulated displacement value Z between the arrival moments is less than the displacement threshold value Z₀The UE will continue at the paging occasion T_n+1The time slots corresponding to inner beams 6, 7, 8 and 9 wake up.

In a specific implementation, if the displacement value Z of the UE is greater than or equal to the displacement threshold value Z₀Then the UE wakes up for a time window equal to one full paging occasion. Specifically, the UE wakes up at the beginning of the paging occasion, and continuously monitors and decodes the network device paging information using the omni-directional beam until the paging information is successfully decoded. And, in the whole paging time machine, the UE simultaneously measures the gain of each transmission beam of the network equipment so as to redetermine the optimal X network equipmentThe beam is transmitted. When the next paging occasion comes, if the displacement value Z of the UE in the sleep period between two paging occasions is smaller than the displacement threshold value Z₀And the UE wakes up in a corresponding time slot in the next paging occasion according to the redetermined optimal transmission beam of the network equipment.

Illustratively, as shown in FIG. 7, if the UE is at the paging occasion T_n+0The displacement value Z of the previous sleep period is greater than or equal to the displacement threshold value Z₀Then at the paging occasion T_n+0At the time of arrival, the UE will be at the entire paging occasion T_n+0The method comprises the steps of keeping awake, monitoring and decoding paging information of the network equipment, and measuring the gain of each transmission beam of the network equipment to re-determine the optimal transmission beams of the X network equipment. For example, if the UE is at paging occasion T when X ═ 4_n+0 Beams 1, 2, 3 and 4 are determined as the optimal transmission beams of the network equipment; then, if the UE is at the paging occasion T_n+0And paging occasion T_n+1The displacement value Z in the sleep period in between is smaller than the displacement threshold value Z₀The UE will be at the paging occasion T_n+1The time slots corresponding to beams 1, 2, 3 and 4 in inner wake up.

In some embodiments, if the UE does not successfully receive paging information for K consecutive paging occasions, the UE will remain awake for the K +1 th paging occasion.

In some cases, the environment around the UE changes, so that the UE cannot receive the paging information even if no obvious displacement occurs. To address such situations, in some embodiments, if the UE does not successfully receive paging information in K consecutive paging occasions, the UE will stay awake to listen for paging information at the K +1 th paging occasion and at the same time re-determine the optimal transmit beams of X network devices.

It should be added that, in the above embodiment, acquiring the device posture information is used, for example: the displacement value of the UE in the dormant state and/or the attitude change value of the UE in the dormant state determine the time window for the network equipment to wake up in the paging time. However, it should be understood that the device attitude information in the embodiment of the present application may include, in addition to the above displacement value and attitude change value, other information that can indicate that the UE has changed position or attitude, for example: the UE may be configured to obtain, from the UE, the barometric pressure information, the acceleration information, the access base station information, the base station signal strength information, the altitude information, and the like in the sleep state.

According to the technical scheme provided by the first embodiment of the application, when the UE adopts the omnidirectional receiving wave beam, the UE obtains the displacement value when the UE enters the dormant state, and adaptively determines the time window for the UE to wake up in the paging time according to the displacement value. Specifically, if the displacement value of the UE in the sleep state is smaller than the preset displacement threshold, the UE awakening time window is a time slot corresponding to the optimal transmission beam of the X network devices determined before the UE enters the sleep state in the paging occasion; and if the displacement value of the UE in the dormant state is greater than or equal to the preset displacement threshold value, the time window awakened by the UE is the whole paging occasion. Therefore, the technical solution provided in the first embodiment of the present application does not require the UE to wake up to perform the beam training before each paging occasion comes, and does not require the UE to stay awake in each complete paging occasion. Therefore, the power consumption of the UE in the DRX mode can be further reduced while the link robustness of the UE and the network equipment is ensured.

The following is a second embodiment of an information receiving method provided in the present application, which is suitable for a scenario in which a UE and a network device communicate with a link using a directional beam.

Fig. 8 is a flowchart of a second embodiment of an information receiving method provided in the present application. As shown in fig. 8, when the UE and the network device communicate to the link using a directional beam, the method may include the steps of:

step S201, when the UE initially accesses the cell, the UE performs complete two-stage wide-narrow beam training to determine X optimal beam pair links by measuring the signal strength of the reference signal synchronization signal block SSB and the channel state information reference signal CSI-RS and the network equipment.

Fig. 9 is a schematic diagram of wide and narrow two-stage beam training. As shown in fig. 9, the network device transmits the SSB beam and the CSI-RS beam in a time-division scanning manner, and the UE also uses a beamforming technique to generate beams in different directions for receiving and transmitting data. The UE adopts a wide transmission beam corresponding to SSB of the wide beam scanning network equipment and a narrow transmission beam corresponding to CSI-RS in an initial access stage, so that the approximate direction of the optimal receiving beam is determined. After the UE feeds back the optimal transmission narrow beam corresponding to the CSI-RS to the network device, the network device instructs the UE to perform beam scanning using the narrow reception beam to determine X optimal (which may be the highest gain) beam pair links, and selects one beam pair link from the X optimal beam pair links for subsequent communication, where each optimal beam pair link includes an optimal transmission narrow beam and an optimal reception narrow beam.

From the UE side, beam training may include the following three phases:

in the first stage, the network device and the UE perform a wide beam scan. The network device periodically performs beam scanning using the cell-level SSB wide beams and the UE receives using the wide beams, thereby determining an optimal wide beam pair between the network device and the UE.

And a second stage, narrow beam scanning of the network device. The network device performs periodic scanning using the CSI-RS narrow beams, and the UE receives using the optimal wide beam determined in the first stage to determine an optimal at least one transmission narrow beam for the network device.

The third phase, narrow beam scanning of the UE. The network equipment uses the optimal CSI-RS narrow beam, and the UE uses the narrow beam to scan the CSI-RS receiving narrow beam, so that the receiving narrow beam matched with the narrow beam sent by the network equipment is determined, and a beam pair link is established.

Step S202, when the UE enters an idle state DRX mode or a non-active state DRX mode, the UE adopts beam forming to carry out directional transmission and directional reception. When the UE enters a sleep state in a DRX mode, the UE acquires own equipment posture information.

In scenarios where the UE employs a directional receive beam, the device attitude information may include a displacement value Z and an attitude change value W generated by the UE during sleep in DRX mode. These device attitude information may be measured from one or more sensors of the UE itself. The displacement value Z of the UE during the sleep period can be measured and obtained through an acceleration sensor of the UE; the attitude change value W of the UE during sleep can be measured by a gyroscope, a geomagnetic sensor, and the like of the UE.

Step S203, when the paging occasion comes, the UE compares the displacement value Z with a preset displacement threshold value Z₀The numerical relation between the attitude change value W and the preset attitude change threshold value W₀The numerical relation between the UE and the paging time frame comprehensively determines the time window of the UE awakening in the paging time frame.

In a specific implementation, if the displacement value Z of the UE is smaller than the displacement threshold value Z₀And the attitude change value W of the UE is smaller than the attitude change threshold value W₀Then, the time window for UE wake-up is the corresponding time slot of the X optimal beam pair links determined by the UE before entering the sleep state in the paging occasion. In the paging time machine, the UE only wakes up in the time slot corresponding to the X optimal wave beam pair link to monitor and decode the paging information of the network equipment. If the paging is carried out, the UE initiates random access to the network equipment; otherwise, the UE is switched into a dormant state beyond the time slots of the X optimal beam pair links.

Illustratively, as shown in fig. 10, if the UE is at the paging occasion T_n+0The previously determined optimal beam pair links are beam pairs 6, 7, 8 and 9, and then the displacement value Z of the UE is smaller than the displacement threshold value Z₀And the attitude change value W is smaller than the attitude change threshold value W₀Then, the UE will be at the paging occasion T_n+0The inner wave beam is awakened to the time slot corresponding to the links 6, 7, 8 and 9, the paging information of the network equipment is monitored and decoded, and if the paging information is paged, the UE initiates random access; if the UE does not receive paging information from the beam pair links 6, 7, 8 and 9, the UE may transition to the sleep state in advance as shown in fig. 10. At the next paging occasion T_n+1At the time of arrival, if the UE reaches the paging occasion T from the moment of determining the optimal beam pair link_n+1The accumulated displacement value Z between the arrival moments is less than the displacement threshold value Z₀And the accumulated attitude change value W is smaller than the attitude change threshold value W₀The UE will continue at the paging occasion T_n+1The inner beam wakes up for the corresponding time slot of links 6, 7, 8 and 9.

In a specific implementation, if the displacement value Z of the UE is greater than or equal to the displacement threshold value Z₀Or the attitude change value W is greater than or equal to the attitude change threshold value W₀The UE wakes up and performs beam training before the paging occasion arrives, and re-determines the X optimal (which may be the highest gain) beam pair link sets of the network device to determine the time slot in which the UE wakes up in the paging occasion. Therefore, when the paging occasion comes, the UE can wake up and monitor the paging information according to the corresponding time slot of the redetermined optimal beam pair link in the paging occasion.

Illustratively, as shown in FIG. 11, if the UE is at the paging occasion T_n+0The displacement value Z of the previous sleep period is greater than or equal to the displacement threshold value Z₀Or the attitude change value W is greater than or equal to the attitude change threshold value W₀Then the UE will be at paging occasion T_n+1And waking up before arrival to perform beam training, and re-determining X optimal beam pair links. For example, if the UE is at paging occasion T when X ═ 4 is_n+1Having re-determined the beam pair links 11, 12, 13 and 14 as the optimal beam pair links before arrival, then at the paging occasion T_n+1In this case, the UE will only wake up and listen to paging messages in the time slots corresponding to the beam pair links 11, 12, 13 and 14.

In some embodiments, if the displacement value Z of the UE is greater than or equal to the displacement threshold Z₀Or the attitude change value W is greater than or equal to the attitude change threshold value W₀The UE may further select a receiving beam from the previously determined X optimal beam pair links, and keep waking up when the paging occasion comes, and listen to the paging information using the selected receiving beam.

Illustratively, as shown in fig. 12, assume that the X optimal beam pair links previously determined by the UE include beam pair links 5, 6, 7, 8; then, if the UE reaches the paging occasion T from the time when the optimal beam pair link is determined_n+1The accumulated displacement value Z between the arrival moments is greater than or equal to a displacement threshold value Z₀Or the accumulated attitude change value W is greater than or equal to the attitude change threshold value W₀The UE may select one reception beam from the reception beams corresponding to the transmission beams 5, 6, 7, and 8, respectively, as shown in fig. 12Beams, e.g. receiving beams 7 corresponding to the transmitting beam 7, and in the paging occasion T_n+1Remains awake and listens for paging information using the receive beam 7.

In some cases, the environment around the UE changes, so that the UE cannot receive the paging information even though no obvious displacement or posture change occurs. To address such situations, in some embodiments, if the UE does not successfully receive paging information in K consecutive paging occasions, the UE wakes up for beam training before the K +1 th paging occasion arrives, re-determines X optimal beam pair links, and determines a time window for the UE to wake up in the K +1 th paging occasion according to a time slot corresponding to the X optimal beam pair links re-determined.

According to the technical scheme provided by the second embodiment of the application, when the UE and the network equipment use the directional beam pair link, the UE obtains the displacement value and the attitude change value of the UE in the dormant state, and adaptively determines the time window for the UE to wake up in the paging time according to the displacement value and the attitude change value. Specifically, if the displacement value and the attitude change value of the UE in the sleep state are both smaller than the corresponding threshold values, the time window awakened by the UE is the corresponding time slot of the X beam pair link sets in the paging occasion determined before the UE enters the sleep state; if the displacement value or the attitude change value of the UE in the dormant state is larger than or equal to the corresponding threshold value, the UE reminds to wake up to perform beam training before the paging occasion comes, and determines X optimal beam pair link sets again so as to determine a corresponding wake-up time window of the UE in the paging occasion; or, the UE selects one receiving beam from the previously determined X optimal beam pair link sets, and keeps waking up to monitor the paging information within the paging occasion. Therefore, in the technical solution provided in the second embodiment of the present application, the UE does not need to wake up to perform beam training before each paging occasion comes, and does not need to remain awake in each complete paging occasion. Therefore, the power consumption of the UE in the DRX mode can be further reduced while the link robustness of the UE and the network equipment is ensured.

The following is a third embodiment of an information receiving method provided in the present application.

Fig. 13 is a flowchart of a third embodiment of an information receiving method provided in the present application. As shown in fig. 13, the method may include steps S301-S304:

step S301, the UE determines a beam receiving mode before entering a Discontinuous Reception (DRX) mode, wherein the beam receiving mode comprises omnidirectional reception and/or directional reception.

In order to overcome the problem of serious attenuation of a received signal caused by path loss in a high-frequency FR2 frequency band wireless communication scene, such as 5G NR, a network device generates a directional transmission beam which is periodically scanned through a beam forming technology to communicate with a UE. At the UE side, the receiving mode can be omnidirectional receiving, namely, the optimal sending beam of the network equipment is selected for information receiving through beam training with the network equipment; or directional reception, that is, determining a matched transmitting-receiving beam pair link through beam training with the network device, and selecting an optimal beam pair link from the links for information reception. For example, the optimal transmission beam of the network device may be the transmission beam with the highest gain, and the optimal beam pair link may be the beam pair link with the highest gain.

Considering that different receiving modes based on omnidirectional, beam forming and the like exist on the UE side, the embodiment of the present application correspondingly adopts different strategies to receive the paging information of the network device in the DRX mode, so as to further reduce the power consumption of the UE in the DRX mode on the premise of ensuring the link robustness between the UE and the network device in any receiving mode.

Step S302, the UE obtains the device attitude information according to the beam receiving mode in the sleep state of the DRX mode, and the device attitude information comprises the displacement value and/or the attitude change value of the UE.

In a specific implementation, when the beam receiving mode is omni-directional receiving, the equipment attitude information includes a displacement value of the UE; when the beam receiving mode is directional receiving, the device attitude information includes a displacement value and an attitude change value of the UE.

When the receiving mode of the UE is omnidirectional receiving, the attitude change of the UE cannot influence the established communication link. However, if the UE is significantly displaced, the link gain of the previously determined optimal transmission beam of the network device on the UE side may be attenuated, resulting in a reception decoding failure. Therefore, when the beam reception manner of the UE is omni-directional reception, the device attitude information includes a displacement value of the UE.

When the beam receiving mode of the UE is directional reception, the UE receives using a wide beam or a narrow beam. Because the rotation of the UE itself may cause the direction of the receiving beam to change, and the displacement of the UE may cause the relative orientation of the UE and the network device to change, the previously determined transmitting beam and receiving beam pair may no longer be the best match, which may cause the gain of the beam pair link to decrease or even fail, thereby causing the failure of receiving the paging information. Therefore, when the beam reception manner of the UE is directional reception, the device attitude information includes a displacement value and an attitude change value of the UE. The device attitude information may be obtained from data measured by various sensors provided with the UE. For example, the displacement value and the attitude change value of the UE may be obtained by an Inertial Measurement Unit (IMU) of the UE.

Step S303, the UE determines an awakening time window according to the equipment posture information, and the time window is positioned in a paging time machine of the network equipment.

In the embodiment of the application, in the DRX mode, the UE adaptively determines a time window to wake up in a paging occasion and a corresponding sleep time according to the device displacement or posture change information, and the UE determines the time window in different ways according to different beam receiving ways, i.e., omni-directional receiving or directional receiving.

The following is a specific explanation of the manner in which the UE determines the time window when using omni-directional reception and directional reception, respectively.

When the beam receiving manner is omni-directional receiving, step S303 may include, as shown in fig. 14, step S401 to step S4022:

in step S401, the UE determines whether the displacement value is smaller than a preset first threshold.

Illustratively, the first threshold has a unit of length (e.g., centimeters (cm)) value that is greater than or equal to 0, e.g., 50 cm. The first threshold may be a fixed value or a variable value; the first threshold may be pre-configured in the UE, or may be indicated to the UE by the network device when the UE communicates with the network device, or may be a value read by the UE from a configuration file. The first threshold is not specifically limited in the embodiment of the present application.

In one embodiment, to determine the displacement value of the UE, a spatial coordinate system for expressing the position of the UE may be established, and the spatial coordinate system may be a rectangular coordinate system as shown in fig. 15, including an x-axis, a y-axis and a z-axis which are orthogonal to each other. Then, any position of the UE in the spatial coordinate system can be described by a three-dimensional vector, i.e. p ═ x, y, z ], where three dimensional values x, y, z of the vector p are coordinate values of the x axis, y axis and z axis of the UE in the rectangular coordinate system.

Based on the rectangular coordinate system of FIG. 15, if the position of the UE before the displacement is p₀＝[x₀,y₀,z₀]At the shifted position p₁＝[x₁,y₁,z₁]Then the UE displacement can be described by a displacement vector Δ p, i.e. Δ p ═ p₁-p₀＝[x₁-x₀,y₁-y₀,z₁-z₀]. Corresponding to the displacement values described by the displacement vector Δ p, the first threshold in the embodiment of the present application may be a threshold vector p_thresh＝[x_thresh，y_thresh，z_thresh]. Based on the above threshold vector, the UE needs to determine the magnitude of the displacement value vector Δ p in step S401, i.e., | Δ p | ═ [ | x |)₁-x₀|,|y₁-y₀|,|z₁-z₀|](the absolute value of each vector element is calculated when applied to the vector) is less than the threshold vector | Δ p | if each dimension value in the displacement vector | Δ p | is less than the threshold vector p_threshCan conclude that the displacement value of the UE is less than the first threshold value if the displacement value along any one dimension in the displacement vector | Δ p | is greater than or equal to the threshold vector p_threshMay conclude that the displacement value of the UE is greater than or equal to the first threshold value.

Illustratively, the UE preset threshold vector p_thresh＝[50,50,50](ii) a In DRX modeIn the following formula, if the position of the UE entering the sleep state after awakening at a certain paging occasion is p₀＝[10,15,0]The position at the arrival time of the next paging occasion is p₁＝[20，-15，10]Then, the displacement value | Δ p | ═ 20-10|, | -15-15|, |10-0|, of the UE in the sleep state]＝[10,30,10]Each dimension value in the displacement value | Δ p | is smaller than p_threshAnd thus the UE concludes that the displacement value is less than the first threshold.

Illustratively, the UE preset threshold vector p_thresh＝[50,50,50](ii) a In DRX mode, if the position of UE entering into sleep state after waking up at a certain paging occasion is p₀＝[10,15,0]The position when the next paging occasion comes is p₁＝[20，-50，10]Then the displacement values | Δ p | ═ 20-10|, | -50-15|, |10-0|, of the UE in the sleep state]＝[10,65,10]At this time, since a variation of 65cm of the displacement value | Δ p | in the y-axis is greater than the corresponding threshold value 50cm, the UE concludes that the displacement value is greater than the first threshold value.

Step S4021, when the displacement value is smaller than a preset first threshold, the UE determines that the time window is a time slot corresponding to the optimal transmission beam of the X network devices in the paging occasion, and the optimal transmission beam of the X network devices is determined by the UE and the network devices according to the beam training and the directional transmission beam of the network devices.

In a specific implementation, the UE may determine the optimal transmit beams of X network devices by using the beam training method shown in fig. 5. Illustratively, the X network device optimal transmit beams may be the X highest gain transmit beams of the network device. For example, when X is 4, if the above 16 transmission beams are beams 7, 8, 6, 9, 5, and 10 … … in order of gain from high to low, the 4 optimal transmission beams that the UE can determine may be beams 6, 7, 8, and 9. Thus, the time window in which the UE wakes up at the paging occasion is the time slot in which the transmit beams 6, 7, 8 and 9 are within the paging occasion.

Step S4022, when the displacement value is greater than or equal to the first threshold, the UE determines the time window as the paging occasion.

In a specific implementation, when the displacement value of the UE is greater than or equal to the first threshold, indicating that the UE has a significant position change during the sleep period, the previously determined X network device transmission beams may therefore no longer be the X transmission beams with the highest gain, which may result in a failure in information transmission between the UE and the user equipment. Therefore, in order to ensure that the UE can receive the paging information when the network device transmits the paging information within the paging occasion, as shown in fig. 7, the UE adjusts the awake time window to the complete paging occasion. Specifically, the UE wakes up at the beginning of the paging occasion, and continuously monitors and decodes the network device paging information using the omni-directional beam until the paging occasion ends or until the paging information decoding is successful.

In some embodiments, when the displacement value of the UE is greater than or equal to the first threshold, the UE maintains a listening state within the paging occasion and re-determines X network device optimal transmit beams from among the transmit beams of the network devices.

In a specific implementation, the UE measures the gain of each transmission beam of the network device in the whole paging time set, so as to re-determine the optimal transmission beams of the X network devices. Therefore, when the next paging occasion comes, if the displacement value of the UE in the sleep period between two paging occasions is smaller than the displacement threshold, the UE may wake up in the corresponding time slot in the "next paging occasion" according to the re-determined optimal transmission beam of the network device.

When the beam receiving manner is omni-directional receiving, step S303 may include, as shown in fig. 16, step S501-step S5022:

in step S501, the UE determines whether the displacement value is smaller than a first threshold and the attitude change value is smaller than a second threshold.

Illustratively, the first threshold has a unit of length (e.g., centimeters "cm") that is greater than or equal to 0, such as 50 cm; the second threshold has the same or different measurement units according to the description mode of the UE posture in the embodiment of the present application. For example, in a rectangular coordinate system, the second threshold is uniformly expressed in an angle system or a radian system (e.g., an angle "°" or a radian "rad"), and takes a value greater than or equal to 0, such as 30 °, pi/6 rad, and the like. The first threshold value and the second threshold value may be fixed values or variable values; the first threshold and the second threshold may be pre-configured in the UE, or may be indicated to the UE by the network device when the UE communicates with the network device, or may be values read by the UE from a configuration file. The first threshold and the second threshold are not specifically limited in the embodiments of the present application.

In one embodiment, to determine the displacement value and the attitude change value of the UE, a spatial coordinate system for expressing the position of the UE may be established, and the spatial coordinate system may be a rectangular coordinate system as shown in fig. 15, including an x-axis, a y-axis and a z-axis which are orthogonal to each other. Then, any position of the UE in the spatial coordinate system can be described by a three-dimensional vector, i.e. p ═ x, y, z ], where three dimensional values x, y, z of the vector p are coordinate values of the x axis, y axis and z axis of the UE in the rectangular coordinate system.

The attitude of the UE in the spatial rectangular coordinate system can be represented by another three-dimensional vector, i.e. q ═ α, β, γ, where the three dimensional values α, β, γ of the vector q are the angular values of the rotation of the UE around the x, y and z axes in the rectangular coordinate system, i.e. the angular values of pitch (pitch), yaw (yaw) and roll (roll), respectively.

Based on the rectangular coordinate system of FIG. 15, if the position of the UE before the displacement is p₀＝[x₀,y₀,z₀]At the shifted position p₁＝[x₁,y₁,z₁]Then the displacement of the UE can be described by a displacement vector | Δ p |, i.e., | Δ p | ═ p |₁-p₀|＝[|x₁-x₀|,|y₁-y₀|,|z₁-z₀|]. Similarly, if the UE attitude q before the attitude change₀＝[α₀，β₀，γ₀]In the attitude q after the attitude change₁＝[α₁，β₁，γ₁]Then the UE attitude change value can be represented by an attitude change vector | Δ q |, where | Δ q | ═ q |, and₁-q₀|＝[|α₁-α₀|，|β₁-β₀|，|γ₁-γ₀|]＝[Δα，Δβ，Δγ]。

corresponding to the above | Δ p | and | Δ q |, the first threshold value in the embodiment of the present application may beIs a displacement threshold vector p_thresh＝[x_thresh，y_thresh，z_thresh]The second threshold may be an angular threshold vector q_thresh＝[α_thresh，β_thresh，γ_thresh]. Based on the above threshold vectors, the UE needs to determine whether the displacement vector | Δ p | and the attitude change vector | Δ q | are smaller than their corresponding displacement threshold vectors p in step S501_threshAnd an angle threshold vector q_thresh(ii) a If each dimension value in the displacement vector | Δ p | is smaller than the value in the threshold vector p_threshIf the dimension value is smaller than the corresponding dimension threshold value, it may be determined that the displacement value of the UE is smaller than the first threshold value; if any at least one dimension value in the displacement vector | Δ p | is greater than or equal to the displacement threshold vector p_threshIf the UE is a corresponding dimension threshold, it may be determined that the displacement value of the UE is greater than or equal to the first threshold; if each dimension value in the angle change vector | Δ q | is smaller than the angle threshold vector q |_threshIf the corresponding dimension threshold value is greater than the first threshold value, it may be determined that the attitude change value of the UE is greater than the second threshold value; if any at least one dimension value in the angle change vector | Δ q | is greater than or equal to the angle threshold vector q_threshThe attitude change value of the UE may be determined to be greater than or equal to the second threshold.

Illustratively, the UE preset displacement threshold vector is p_thresh＝[50,50,50]The attitude change threshold vector is q_thresh＝[15,15,15](ii) a In DRX mode, if the position of the time when the UE enters the dormant state after a certain paging occasion is p₀＝[10,15,0]Attitude q₀＝[45,10,1](ii) a The position at the arrival time of the next paging occasion is p₁＝[20,-15,10]In an attitude of q₁＝[48,10,5]Then the displacement value of the UE in the sleep state is | Δ p | [ |20-10|, | 15-15|, |10-0|]＝[10,30,10]. It will be readily seen that each element in the displacement value | Δ p | represents a change along the x-, y-, z-axes of less than p_threshSo that the UE determines that the displacement value is less than the first threshold; similarly, the posture change value of the UE in the sleep state is | Δ q | [ |48-45|, |10-10, |5-1|, non-volatile memory]＝[3,0,4]The variation value along each dimension is less thanq_threshSo that the UE determines that the attitude change value is less than the second threshold.

Illustratively, if the location of the UE at the next paging occasion arrival time is p₁＝[10,-60,85]Then, the displacement value in the sleep state is | Δ p | [ |10-10|, - | -60-15|, |85-0|]＝[0,75,85]At this time, since the y-axis dimension value 75 and the z-axis dimension value 85 of the displacement value | Δ p | are both greater than the corresponding dimension threshold 50, the UE determines that the displacement value is greater than the first threshold.

Illustratively, if the UE has an attitude of q at the time of arrival of the next paging occasion₁＝[39,11,5]Then, the posture change value in the sleep state is | Δ q [ |39-45|, |11-10|, |5-1|]＝[6,4,1]. At this time, since the change value 6 along the x-axis represented by the posture change vector | Δ q | is greater than the corresponding threshold value 5, the UE determines that the posture change value is greater than the second threshold value.

Step S5021, when the displacement value is smaller than a preset first threshold value and the attitude change value is smaller than a preset second threshold value, the UE determines that the time window is a corresponding time slot of X optimal beam pair links in the paging occasion, and the X optimal beam pair links are determined by the UE and the network equipment according to beam training and a beam pair link between the network equipment and the UE.

In a specific implementation, the UE and the network device may perform beam training according to the method shown in fig. 9 to determine X optimal beam pair links. Illustratively, the X optimal beam pair links may be the X highest gain beam pair links between the network device and the UE. For example, when X is 4, if the UE determines through beam training that the beam pair links between the network device and the UE are beam pair links 7, 8, 6, 9, 5, and 10 … … in order of gain from high to low, the 4 optimal beam pair links that the UE can determine may be beam pair links 6, 7, 8, and 9. Thus, the time window in which the UE wakes up at the paging occasion is the time slot in the paging occasion for the beam pair links 6, 7, 8 and 9.

Step S5022, when the displacement value is greater than or equal to the first threshold value, or the attitude change value is greater than or equal to the second threshold value, the UE re-determines the time slot corresponding to the optimal transmission beam of the X network devices in the paging occasion.

In a specific implementation, when the displacement value of the UE is greater than or equal to the first threshold, or the posture change value is greater than or equal to the second threshold, it indicates that the UE has a significant position or posture change during the sleep, and the previously determined beam pair link may therefore no longer be the beam pair link with the highest gain, which may result in a failure in information transmission between the UE and the user equipment. Therefore, in order to ensure that the UE can receive the paging information when the network device transmits the paging information within the paging occasion, as shown in fig. 12, the UE adjusts the awake time window to the complete paging occasion. Specifically, the UE wakes up at the beginning of the paging occasion, selects a receiving beam to continuously monitor and decode the paging information of the network device until the paging occasion is ended or until the paging information is successfully decoded.

In some embodiments, when the displacement value is greater than or equal to the first threshold or the attitude change value is greater than or equal to the second threshold, the UE wakes up before the paging occasion comes and determines X optimal beam pair links again.

In a specific implementation, the UE may wake up for beam training before the paging occasion comes, so as to re-determine X optimal beam pair links. Therefore, when the next paging occasion comes, as shown in fig. 11, the UE may wake up and listen to the paging information according to the corresponding time slot of the re-determined optimal beam pair link in the paging occasion.

Step S304, the UE wakes up in the time window selected in the paging timer and receives the paging information.

In specific implementation, if the UE is paged, the UE initiates random access to the network device; if not paged, the UE will continue to enter the dormant state after the paging occasion is over, so as to save power consumption.

In some cases, the environment around the UE changes, so that the UE cannot receive the paging information even if no obvious displacement occurs. To cope with such a situation, in some embodiments, when the beam receiving manner is omni-directional receiving, if the UE does not successfully receive paging information in K consecutive paging occasions, the UE keeps waking up to listen to the paging information at the K +1 th paging occasion, and at the same time, determines X optimal transmission beams of the network device again.

In some cases, the environment around the UE changes, so that the UE cannot receive the paging information even though no obvious displacement or posture change occurs. To address such situations, in some embodiments, when the beam reception mode is directional reception, if the UE does not receive paging information within K consecutive paging occasions, the UE determines the awake time window to be the K +1 th paging occasion. In specific implementation, the UE may wake up for beam training before the K +1 th paging occasion arrives, re-determine the X optimal beam pair links, and determine a time window for the UE to wake up in the K +1 th paging occasion according to the time slot corresponding to the X optimal beam pair links re-determined in quota.

In some embodiments, the UE obtains a third threshold, and a value of the third threshold is greater than 0 and smaller than the first threshold. The third threshold may be pre-configured in the UE, or may be indicated to the UE by the network device when the UE communicates with the network device, or may be a value read by the UE from a configuration file. The third threshold is not specifically limited in the embodiment of the present application.

In some embodiments, when the UE employs omni-directional reception, if a displacement value generated by the UE in a sleep state of the DRX mode is greater than a third threshold and less than a first threshold, an awake window of the UE in a paging occasion includes not only a slot corresponding to the X network device optimal transmission beams determined by the UE but also a slot corresponding to at least one transmission beam adjacent to the network device optimal transmission beam. Therefore, when the UE generates displacement but the amplitude is not significant, the UE can improve the success rate of receiving the paging information by increasing the awakening time slot, reduce the probability of the extreme condition that the paging information cannot be successfully decoded at the K paging occasions, and further reduce the times of beam training so as to reduce the power consumption.

FIG. 17 is a schematic illustration of a wake-up window with a displacement value greater than a third threshold and less than a first threshold. As shown in fig. 17, the UE determines the network device optimal transmit beams 6, 7, 8, 9 from the 16 transmit beams of the network device through beam training. When the displacement value of the UE is greater than the third threshold and smaller than the first threshold, the UE wakes up not only at the time slot of the beams 6, 7, 8, and 9, but also at the adjacent beam 5 and beam 10, so as to achieve the above-mentioned effects of improving the success rate of successfully decoding the paging information and reducing power consumption.

In some embodiments, the UE further obtains a fourth threshold for the attitude change value on the basis of obtaining the third threshold, and a value range of the fourth threshold is greater than 0 and smaller than the second threshold. The fourth threshold may be pre-configured in the UE, or may be indicated to the UE by the network device when the UE communicates with the network device, or may be a value read by the UE from a configuration file. The fourth threshold is not specifically limited in the embodiment of the present application. When the UE adopts directional reception, if a displacement value generated by the UE in a sleep state of a DRX mode is larger than a third threshold and smaller than a first threshold, or an attitude change value is larger than a fourth threshold and smaller than a second threshold, an awakening window of the UE at a paging occasion not only comprises time slots corresponding to X network equipment optimal transmission beams determined by the UE, but also comprises time slots corresponding to at least one transmission beam adjacent to the network equipment optimal transmission beam. Therefore, when the UE generates displacement or posture change but the amplitude is not obvious, the UE can improve the success rate of receiving the paging information by increasing the awakening time slot, reduce the probability of the extreme condition that the paging information cannot be successfully decoded at the K paging occasions, and further reduce the times of beam training so as to reduce the power consumption.

Fig. 18 is a schematic diagram of a wake-up window with a UE attitude change value greater than a fourth threshold and less than a second threshold. As shown in fig. 18, the UE determines the optimal beam pair links 6, 7, 8, 9 from the 16 beam pair links through beam training. When the displacement value of the UE is greater than the third threshold and less than the first threshold, or the attitude change value is greater than the fourth threshold and less than the second threshold, the UE wakes up not only at the time slot of the beam pair links 6, 7, 8, 9, but also at the adjacent beam pair link 5 and beam pair link 10, so as to achieve the above-mentioned purposes of improving the success rate of receiving paging information and reducing power consumption.

In the method provided in the third embodiment of the present application, the UE acquires a beam receiving mode before entering the sleep state, and determines, according to the beam receiving mode, corresponding device posture information, that is, a displacement value or a posture change value, etc., that the UE should acquire in the sleep state, and determines, according to the displacement and posture change amplitude of the UE during the sleep period, which are characterized by the device posture information, a time window for receiving paging information in a paging server, and wakes up to monitor the paging information only in the determined specific time window. Therefore, in the method provided in the third embodiment of the present application, the UE does not need to wake up to perform beam training before each paging occasion comes, and does not need to keep waking up in each complete paging occasion, so that the link robustness between the UE and the network device is ensured, the wake-up time of the UE is reduced, and the power consumption of the UE in the DRX mode is further reduced.

In one embodiment, the user equipment UE implements the required functionality by means of the hardware architecture shown in fig. 19. Specifically, the information receiving apparatus includes a processor 601, a transceiver 602, and a memory 603. The transceiver 602 and the memory 603 are electrically coupled to the processor 601.

In some embodiments, the information receiving apparatus further includes a sensor module 604 for acquiring device position and orientation information. The sensor module 604 may include an acceleration sensor 604A or a gravity sensor 604B for measuring acceleration data of the device motion to estimate a displacement value of the device; a gyroscope 604C for measuring angular acceleration data of the apparatus to obtain an attitude change value of the apparatus; a geomagnetic sensor 604D for measuring orientation data of the apparatus to assist in calculating an attitude change value of the apparatus.

The device provided by the embodiment of the application is used for acquiring the beam receiving mode before the device enters the sleep state, and acquiring the device attitude information such as the displacement value or the attitude change value of the device in the sleep state according to the beam receiving mode. According to the displacement or attitude change amplitude of the device embodied by the attitude information of the equipment during the sleep period, the time window for receiving the paging information in the paging time is determined, and the device only wakes up in the determined specific time window to receive the paging information. Therefore, the device does not need to wake up to perform beam training before each paging occasion comes, and does not need to keep waking up in each complete paging occasion, so that the link robustness of the device and network equipment is ensured, meanwhile, the wake-up time of the device is reduced, and the power consumption of the device in the DRX mode is further reduced.

Therefore, the device adaptively determines the time window for waking up in the paging time according to the displacement value, thereby reducing the waking time of the device and further reducing the power consumption of the device in the DRX mode while ensuring the link robustness of the device and the network equipment.

In an alternative embodiment, the processor 601 is configured to determine whether the displacement value is smaller than a first threshold value and the attitude change value is smaller than a second threshold value when the beam receiving mode is directional receiving; a processor 601, configured to determine, when the displacement value is smaller than a preset first threshold and the attitude change value is smaller than a preset second threshold, that a time window is a time slot corresponding to X optimal beam pair links in a paging occasion, where the X optimal beam pair links are determined by the device and the network apparatus according to beam training and a beam pair link between the network apparatus and the device; the processor 601 is further configured to determine the time window as a paging occasion when the displacement value is greater than or equal to the first threshold or the attitude change value is greater than or equal to the second threshold. Therefore, the device adaptively determines the time window for waking up in the paging time according to the displacement value and the attitude change value, thereby reducing the waking time of the device and further reducing the power consumption of the device in the DRX mode while ensuring the link robustness of the device and the network equipment.

In an alternative embodiment, the transceiver 602 is configured to maintain a listening state in the paging occasion when the displacement value is greater than or equal to a first threshold value; a processor 601, configured to re-determine the X optimal transmission beams of the network device from the transmission beams of the network device. Therefore, when the position of the device is changed remarkably, the device is awakened at the next complete paging occasion, and the optimal transmitting beams of the X network devices and the corresponding awakened time windows are determined while the paging information is monitored.

In an alternative embodiment, the processor 601 is configured to re-determine the X optimal beam pair links before the paging occasion comes when the displacement value is greater than or equal to the first threshold or the posture change value is greater than or equal to the second threshold. Therefore, when the position or the posture of the device is changed remarkably, X optimal beam pair links are determined again through beam training, and therefore in the next paging time machine, the awakening time window can be determined according to the latest optimal beam pair link time slot.

In an alternative embodiment, the processor 601 is configured to determine the awake time window to be the K +1 th paging occasion when the transceiver does not receive paging information for K consecutive paging occasions. Thus, when the device has not been significantly displaced but still cannot wake up and receive paging information within a previously determined specific time window, the device sets the awake time window to the entire paging occasion, ensuring that paging information can be received.

In an alternative embodiment, the processor 601 is configured to, when the transceiver does not receive paging information in K consecutive paging occasions, re-determine X optimal beam pair links before the K +1 th paging occasion arrives, and determine an awake time window as a corresponding slot of the re-determined X optimal beam pair links in the K +1 th paging occasion. Thus, when the device has not undergone significant displacement or attitude change but still cannot wake up and receive paging information within a previously determined specific time window, the device sets the awake time window to the entire paging occasion, ensuring that paging information can be received.
