[0031] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.
[0032] In order to achieve low power consumption as much as possible, when no service is activated, the terminal will switch to an energy-saving state (also known as a standby state), which will reduce the terminal's functions to a certain extent (such as disconnecting the control plane connection). At this time, the network equipment will not be able to obtain the terminal's location (i.e., which serving cell it is in), resulting in the inability to achieve data transmission.
[0033] To avoid this situation, the network device initiates paging before data transmission is required to request to establish or restore a connection. Correspondingly, after entering the standby state, the terminal usually needs to perform paging detection to avoid missing a paging message.
[0034] Figure 1 A schematic diagram of paging detection provided by an exemplary embodiment of the present application is shown.
[0035] The specific process of paging detection involves radio frequency (RF) devices and terminals. In some embodiments, the terminal can be implemented as a mobile terminal device, or as a baseband chip (BB), and the BB can be set in the mobile terminal device. The following takes the terminal as an example.
[0036] Exemplarily, the network device sends a paging message via RF, and includes two paging occasions (paging occasion 0 and paging occasion 1), each of which can be regarded as a paging cycle. To detect the RF signal carrying the paging message, the BB always keeps the RF component (which can be understood as a device that receives RF signals) turned on in each paging cycle.
[0037] At the same time, in order to detect the paging message, BB needs to ensure that the hardware (HardWare, HWA) associated with the physical downlink control channel (Physical Downlink Control Channel, PDCCH), physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), data plane processing interface (Data Plane processing interface, DP) and protocol stack processing interface (Protocol Stack processing interface, PS) remain turned on in real time. It can be understood that BB needs to ensure that PDCCH / PDSCH / DP / PS HWA is always turned on.
[0038] refer to Figure 1 , at the start time unit of paging occasion 0, PDCCH / PDSCH / DP / PS HWA is in the on state. Among them, PDCCH HWA is used to implement PDCCH detection (PDCCH Detcion), and PDSCH HWA is in the running state (PDSCHHWA standy), and PS / DP is also in the running state (PS / DP standy).
[0039] However, the probability of a terminal receiving a paging message when in standby mode is low. If the hardware involved in paging detection (ie, PDCCH / PDSCH / DP / PS HWA) is always turned on, the power consumption of the terminal will be relatively high.
[0040] Based on this, an embodiment of the present application provides a paging detection method, which is executed by a terminal. Referring to the above content, the terminal can be implemented as a mobile terminal device or a baseband chip, so the method can be executed by the mobile terminal device, or the method can be executed by the baseband chip.
[0041] Figure 2 A flow chart of a paging detection method provided by an exemplary embodiment of the present application is shown, comprising the following steps:
[0042] Step 202: Obtain the detection result of PDCCH.
[0043] PDCCH carries scheduling and other control information, such as transmission format, resource allocation, uplink scheduling permission, power control, and uplink retransmission information, etc. During paging detection, the terminal can detect PDCCH to obtain whether the detection result includes paging scheduling indication information.
[0044] Exemplarily, the detection result of the PDCCH includes the following two cases:
[0045] PDCCH carries indication information for indicating paging scheduling;
[0046] The PDCCH does not carry any indication information for indicating paging scheduling.
[0047] In some embodiments, if the detection result of the PDCCH includes the indication information of the paging schedule, the terminal establishes or restores the connection with the network device. Conversely, if the detection result of the PDCCH does not include the indication information of the paging schedule, it is determined that the terminal and the network device do not need to establish or restore the connection in the current paging cycle.
[0048] Optionally, the indication information for indicating the paging schedule includes downlink control information (Downlink Control Information, DCI). It can be understood that the PDCCH carries the DCI, and the DCI is used to indicate associated information of a paging schedule.
[0049] Subsequently, if the PDCCH carries indication information for indicating paging scheduling, the terminal can determine the specific process of establishing or restoring the connection by detecting the PDSCH. It can be understood that based on the detection of the PDCCH, it is determined that there is a paging signal; then the hardware associated with the PDSCH is turned on to detect the paging message. Among them, turning on the hardware associated with the PDSCH can also be understood as waking up the hardware associated with the PDSCH.
[0050] In some embodiments, the detection result of the PDCCH needs to be detected by associated hardware (which can be expressed as PDCCH HWA). Optionally, the hardware associated with the PDCCH includes but is not limited to at least one of the following hardware: a channel estimation processor, an equalizer, and a first decoder corresponding to the PDCCH. The first decoder includes a Polar decoder and / or a Viterbi decoder. The Polar decoder is used for the 5th generation (the 5 th Generation, 5G) communications, the Viterbi decoder is used for the 4th generation (the th Generation, 4G) communications.
[0051] Optionally, to obtain the detection result of PDCCH, the paging detection method provided in the embodiment of the present application further includes: turning on the PDCCH-associated hardware at the start time unit of the first paging cycle. Wherein, at the start time unit of the first paging cycle, the PDSCH-associated hardware (which can be expressed as PDSCH HWA) is in a turned-off state.
[0052] refer to Figure 1 Unlike the related art in which PDCCH / PDSCH / DP / PS HWA is kept turned on all the time, the paging detection method provided in the embodiment of the present application only needs to turn on the hardware associated with PDCCH, thereby reducing the power consumption of PDCCH / PDSCH / DP / PS HWA.
[0053] Step 204: Determine whether to enable the first hardware associated with the PDSCH according to the indication of the paging scheduling in the detection result of the PDCCH.
[0054] Illustratively, the first hardware is used to receive a paging message indicated by a paging schedule, where the paging message is carried in a PDSCH. The first hardware may be represented as a PDSCH HWA.
[0055] In some embodiments, when the network device needs to establish or restore a connection with a terminal, the network device will initiate a paging process. The core network (CN) sends a paging message to the radio access network (RAN) through the Iu interface, and the RAN sends the paging message of the CN to the terminal through the Uu interface, so that the paged terminal initiates a signaling connection establishment process with the CN after receiving the paging message. Specifically, the paging message is carried in the PDSCH. It should be understood that based on turning on the first hardware, the terminal can detect the PDSCH, thereby obtaining the paging message to establish a connection with the network device.
[0056] Optionally, the first hardware includes at least one of the following hardware: a channel estimation processor; an equalizer; and a second decoder corresponding to the PDSCH. The second decoder includes a low-density parity check (LDPC) decoder and / or a Turbo decoder, the LDPC decoder is used for 5G communication, and the Turbo decoder is used for 4G communication.
[0057] The activation of the first hardware is determined according to the indication of paging scheduling in the detection result of the PDCCH. Referring to the above content, the detection result of the PDCCH includes the following two situations: the PDCCH carries indication information for indicating paging scheduling; the PDCCH does not carry indication information for indicating paging scheduling.
[0058] In some embodiments, when the PDCCH carries indication information for indicating paging scheduling, the first hardware associated with the PDSCH is turned on. Turning on the first hardware can also be understood as waking up the first hardware. Optionally, according to the detection result of the PDSCH, it is determined whether to start the interface processing. The interface processing includes: the processing corresponding to the DP and / or the processing corresponding to the PS.
[0059] For example, when the terminal detects through the first hardware, it detects that the PDSCH carries data plane related processing information (such as the PDSCH carries a data packet to be received), and the DP-associated hardware (which can be expressed as DP HWA) can be turned on at this time to facilitate the interface processing corresponding to the DP. Among them, the DP-associated hardware includes but is not limited to: data unpacking and / or packaging components, encryption and decryption components, etc.
[0060] For another example, when the terminal detects through the first hardware, it is detected that the PDSCH carries processing information related to the protocol stack (such as the PDSCH carries web page information that needs to be displayed), and the PS-associated hardware (which can be expressed as PSHWA) can be turned on at this time to facilitate the interface processing corresponding to the PS. Among them, the PS-associated hardware includes but is not limited to the central processing unit (CPU) related to the protocol processing.
[0061] In other embodiments, when the PDCCH does not carry the indication information for indicating the paging scheduling, the RF component is turned off. The RF component can be understood as one or more devices that receive RF signals. Turning off the RF component will effectively reduce the power consumption caused by receiving RF signals (compared to keeping the RF component always turned on, it will reduce the power consumption caused by RF reception by at least 50%), thereby further reducing the power consumption of the terminal.
[0062] Optionally, to ensure that the RP signal is not missed, the RF component will be restarted at the start time unit of the next paging cycle to facilitate detection of the next paging cycle. For example, at the start time unit of the first paging cycle, the RF component is turned on and the detection result of the PDCCH is obtained; if the PDCCH does not carry the indication information for indicating the paging scheduling, the RF component is turned off; then, at the start time unit of the second paging cycle, the RF component is restarted. The second paging cycle is the paging cycle after the first paging cycle.
[0063] In summary, in the paging detection method provided in the embodiment of the present application, whether to turn on the first hardware associated with the PDSCH is determined according to the detection result of the PDCCH, so that the first hardware does not need to be kept turned on in real time, so as to achieve the purpose of saving power consumption. Wherein, the turning on of the first hardware is determined according to the indication of the paging scheduling in the detection result of the PDCCH.
[0064] Since the first hardware associated with PDSCH consumes relatively high power, linking the activation of the first hardware with the detection result of PDCCH will enable the first hardware to be activated when needed and deactivated when not needed, thereby avoiding high power consumption caused by the first hardware.
[0065] In some embodiments, if the terminal is in standby mode, the probability of detecting paging scheduling through PDCCH is low (maybe no more than 1%), and shutting down the first hardware in time when not needed can relatively save the large power consumption related to PDSCH (close to 99%).
[0066] Referring to the above content, the activation of the first hardware is determined according to the indication of the paging scheduling in the detection result of the PDCCH. Among them, the detection result of the PDCCH includes the following two situations: the PDCCH carries the indication information for indicating the paging scheduling; the PDCCH does not carry the indication information for indicating the paging scheduling. According to different results, the paging detection method includes the following two different steps:
[0067] 1. PDCCH carries indication information for indicating paging scheduling.
[0068] refer to Figure 2 , Figure 3 The flowchart of a paging detection method provided by an exemplary embodiment of the present application is shown. Among them, step 204 can be implemented as step 2041, and the paging detection method provided by the embodiment of the present application also includes step 206, which is as follows:
[0069] Step 2041: When the PDCCH carries indication information for indicating paging scheduling, the first hardware associated with the PDSCH is turned on.
[0070] Illustratively, the first hardware is used to receive a paging message indicated by a paging schedule, where the paging message is carried in a PDSCH.
[0071] In some embodiments, when the network device needs to establish or restore a connection with a terminal, the network device will initiate a paging process. The CN sends a paging message to the RAN via the Iu interface, and the RAN sends the CN's paging message to the terminal via the Uu interface, so that the paged terminal initiates a signaling connection establishment process with the CN after receiving the paging message. Specifically, the paging message is carried in the PDSCH, and the terminal can obtain the paging message by detecting the PDSCH to establish a connection with the network device.
[0072] Referring to the above content, the first hardware includes at least one of the following hardware: a channel estimation processor; an equalizer; and a second decoder corresponding to the PDSCH, wherein the second decoder includes an LDPC decoder and / or a Turbo decoder.
[0073] The activation of the first hardware is determined according to the indication of the paging scheduling in the detection result of the PDCCH. Referring to the above content, the detection result of the PDCCH includes the following two situations: the PDCCH carries the indication information for indicating the paging scheduling; the PDCCH does not carry the indication information for indicating the paging scheduling. The embodiment of the present application only considers the first situation.
[0074] Take the case where the terminal is implemented as BB, Figure 4A schematic diagram of paging detection provided by an exemplary embodiment of the present application is shown. The network device sends a paging message via RF, and includes two paging occasions (paging occasion 0 and paging occasion 1), each of which can be regarded as a paging cycle. To detect the RF signal carrying the paging message, the BB turns on the RF component at the start time unit of each paging cycle.
[0075] refer to Figure 4 At the start time unit of each paging cycle, the BB can turn on the PDCCH HWA to implement PDCCH detection. At the same time, at the start time unit of each paging cycle, the BB turns off the PDSCH / DP / PS HWA to reduce unnecessary power consumption.
[0076] Subsequently, since PDCCH carries indication information for indicating paging scheduling (ie, PDCCH and PDSCH exist in paging occasion 0 shown in the figure), BB can turn on PDSCH HWA (ie, the first hardware involved in this application). Optionally, during the time unit when PDSCH HWA is turned on, DP / PS HWA remains turned off.
[0077] Step 206: Determine whether to start interface processing according to the detection result of the PDSCH.
[0078] Illustratively, the interface processing includes: processing corresponding to DP and / or processing corresponding to PS.
[0079] After the first hardware is turned on, the terminal can obtain the detection result of the PDSCH through the first hardware. Referring to the above content, during the time unit when the first hardware is turned on, the DP / PS HWA remains turned off. Subsequently, the terminal can determine whether to turn on the DP / PS HWA based on the detection result of the PDSCH to start the corresponding interface processing.
[0080] Exemplarily, in the detection result of PDSCH, in addition to being able to obtain a paging message to establish a connection with a network device, the following two situations are also included: PDSCH carries processing information related to the data plane; PDSCH carries processing information related to the protocol stack. Based on the above two situations, the terminal can start the DP / PS-associated hardware to start the corresponding interface processing. Among them, the interface processing includes: the processing corresponding to the DP, and / or the processing corresponding to the PS.
[0081] In some embodiments, when the terminal detects through the first hardware that the PDSCH carries processing information related to the protocol stack (such as the PDSCH carries web page information that needs to be displayed), the PS-related hardware can be turned on to facilitate the interface processing corresponding to the PS. The PS-related hardware includes but is not limited to the CPU related to the protocol processing.
[0082] Still taking the terminal implementation as BB as an example, refer to Figure 4 After PDSCH HWA is turned on, the terminal can implement PDSCH detection to further detect paging messages. Optionally, if PDSCH also carries processing information related to the protocol stack, the PS-related hardware is turned on to perform PS interface processing (PS processing). Among them, turning on the PS-related hardware can also be understood as waking up the PS-related hardware (wake up PS if necessary).
[0083] In other embodiments, when the terminal detects through the first hardware that the PDSCH carries data plane related processing information (such as the PDSCH carries a data packet to be received), the DP-associated hardware (which can be expressed as DP HWA) can be turned on to facilitate the interface processing corresponding to the DP. The DP-associated hardware includes but is not limited to: data unpacking and / or packaging components, encryption and decryption components, etc.
[0084] Similar to the PS interface processing, if the PDSCH also carries data plane related processing information, the DP-related hardware is enabled to perform DP interface processing (DP processing). Among them, enabling the DP-related hardware can also be understood as waking up the DP-related hardware (wake up DP if necessary).
[0085] Exemplarily, starting the DP / PS interface processing is an optional step, which is determined according to the detection result of the PDSCH. If the PDSCH does not carry relevant processing information, there is no need to start the DP / PS associated hardware. Based on this, the associated hardware will remain in a closed state, thereby further reducing the power consumption of the terminal.
[0086] 2. PDCCH does not carry indication information for indicating paging scheduling.
[0087] refer to Figure 2 , Figure 5 A flowchart of a paging detection method provided by an exemplary embodiment of the present application is shown. Step 202 can be implemented as step 2021. The paging detection method provided by the embodiment of the present application also includes step 201, step 2051 and step 2052, which are specifically as follows:
[0088] Step 201: In the starting time unit of the first paging cycle, start the second hardware associated with the PDCCH.
[0089] Illustratively, the second hardware is used to obtain a detection result of the PDCCH, and the first hardware is in a closed state at a start time unit of the first paging cycle.
[0090] The first hardware is used to receive the detection result of the PDCCH, and the specific description can refer to the above content.
[0091] Optionally, the second hardware includes at least one of the following hardware: a channel estimation processor; an equalizer; and a first decoder corresponding to the PDCCH. The first decoder includes a Polar decoder and / or a Viterbi decoder, the Polar decoder is used for 5G communication, and the Viterbi decoder is used for 4G communication.
[0092] Referring to the above content, to obtain the detection result of PDCCH, it is necessary to start the hardware associated with PDCCH (ie, the second hardware), which can be represented as PDCCH HWA. Based on starting the second hardware, the terminal can detect PDCCH and thus determine whether to start the first hardware.
[0093] Step 2021: In the first paging cycle, obtain the detection result of PDCCH.
[0094] Still taking the terminal implementation as BB as an example, Figure 6 A schematic diagram of paging detection provided by an exemplary embodiment of the present application is shown. Among them, the network device sends a paging message via RF, and includes two paging occasions (paging occasion 0 and paging occasion 1), and each paging occasion can be regarded as a paging cycle. Paging occasion 0 can be understood as the first paging cycle, and paging occasion 1 can be understood as the second paging cycle located after the first paging cycle. Accordingly, in order to detect the RF signal carrying the paging message, the BB turns on the RF component at the start time unit of each paging cycle.
[0095] At the start time unit of the first paging cycle, the BB turns on the PDCCH HWA (ie, the second hardware) to implement PDCCH detection. At the same time, at the start time unit of the first paging cycle, the BB turns off the PDSCH / DP / PS HWA to reduce unnecessary power consumption.
[0096] It should be understood that, when the PDCCH carries indication information for indicating paging scheduling, step 201 and step 2021 are also optional steps. That is, in the embodiment given in the foregoing content, at the start time unit of the first paging cycle, the terminal can turn on the second hardware to obtain the detection result of the PDCCH.
[0097] Step 2051: When the PDCCH does not carry indication information for indicating paging scheduling, turn off the radio frequency component.
[0098] Referring to the above content, the detection result of PDCCH includes the following two situations: PDCCH carries indication information for indicating paging scheduling; PDCCH does not carry indication information for indicating paging scheduling. The embodiment of the present application only considers the second situation.
[0099] Still taking the terminal implementation as BB as an example, refer to Figure 6 For paging occasion 0, by detecting the PDCCH, it is determined that the PDCCH does not carry the indication information for indicating the paging scheduling. After detecting the PDCCH, the terminal can turn off the RF component to reduce power consumption. For paging occasion 1, based on the fact that the PDCCH does not carry the indication information for indicating the paging scheduling, the RF component is also turned off after detecting the PDCCH.
[0100] Optionally, based on the fact that the PDCCH does not carry indication information for indicating paging scheduling, the PDSCH / DP / PS HWA is always in a closed state.
[0101] Step 2052: Restart the radio frequency component at the start time unit of the second paging cycle.
[0102] Illustratively, the second paging cycle is a paging cycle located after the first paging cycle.
[0103] refer to Figure 6 , the second paging cycle is paging opportunity 1, and at the start time unit of paging opportunity 1, the terminal will restart the RF component to obtain the RF signal in the second paging cycle. Referring to step 2051 and step 2052, it can be understood that in the first paging cycle, from the time unit after the PDCCH is detected to the end time unit of paging opportunity 0, the RF component is in a closed state to save the power consumption of the RF component; at the start time unit of the second paging cycle, the terminal can restart the RF component to ensure that the RF signal in the second paging cycle is not lost.
[0104] In summary, in the paging detection method provided in the embodiment of the present application, different implementation methods are respectively provided based on the two detection results of the PDCCH.
[0105] On the one hand, when the PDCCH carries indication information for indicating paging scheduling, the first hardware is turned on. Optionally, determining whether to start interface processing based on the detection result of the PDSCH can reduce the power consumption of DP / PS-related hardware to a certain extent, thereby further saving terminal power consumption.
[0106] On the other hand, when the PDCCH does not carry indication information for indicating paging scheduling, the RF component is turned off and restarted at the start time unit of the next paging cycle to avoid invalid power consumption of the RF component and further save terminal power consumption.
[0107] It should be understood that the multiple embodiments given in the foregoing content can be implemented separately or in combination, and the combined implementation is also within the protection scope of this application.
[0108] For example, taking the terminal as BB, Figure 7 A schematic diagram of paging detection provided by an exemplary embodiment of the present application is shown. Among them, the network device sends a paging message via RF, and includes two paging opportunities (paging opportunity 0 and paging opportunity 1), and each paging opportunity can be regarded as a paging cycle. In the embodiment of the present application, paging opportunity 0 can be understood as the first paging cycle, and paging opportunity 1 can be understood as the second paging cycle located after the first paging cycle. Accordingly, in order to detect the RF signal carrying the paging message, the BB turns on the RF component at the start time unit of the first paging cycle.
[0109] In some embodiments, the paging detection method provided in the embodiments of the present application is implemented as follows:
[0110] Step 1: Enable PDCCH HWA at the start time unit of the first paging cycle .
[0111] Schematically, PDCCH HWA is used to obtain the detection result of PDCCH. Meanwhile, in the starting time unit of the first paging cycle, PDSCH / DP / PS HWA is in a closed state to reduce unnecessary power consumption. Among them, PDSCH HWA is used to obtain the detection result of PDCCH, and DP / PS HWA is used to start interface processing.
[0112] Optionally, the PDCCH HWA includes at least one of the following hardware: a channel estimation processor; an equalizer; and a first decoder corresponding to the PDCCH. The first decoder includes a Polar decoder and / or a Viterbi decoder, the Polar decoder is used for 5G communication, and the Viterbi decoder is used for 4G communication.
[0113] Optionally, the PDSCH HWA includes at least one of the following hardware: a channel estimation processor; an equalizer; and a second decoder corresponding to the PDSCH. The second decoder includes an LDPC decoder and / or a Turbo decoder, the LDPC decoder is used for 5G communication, and the Turbo decoder is used for 4G communication.
[0114] Optionally, the PS HWA includes but is not limited to: a CPU related to protocol processing.
[0115] Optionally, DP HWA includes but is not limited to: data unpacking and / or packaging components, and encryption and decryption components.
[0116] Step 2: In the first paging cycle, obtain the detection result of PDCCH.
[0117] The detection result of the PDCCH includes the following two situations: the PDCCH carries indication information for indicating paging scheduling; and the PDCCH does not carry indication information for indicating paging scheduling.
[0118] Optionally, the indication information used to indicate paging scheduling includes DCI.
[0119] refer to Figure 7 At the start time unit of paging occasion 0 (ie, the first paging cycle), the BB turns on the PDCCH HWA and keeps the PDSCH / DP / PS HWA turned off, so as to perform PDCCH detection through the PDCCH HWA.
[0120] Wherein, if the PDCCH does not carry the indication information for indicating the paging scheduling, step 3 is performed; if the PDCCH carries the indication information for indicating the paging scheduling, step 4 is performed, which is specifically as follows:
[0121] Step 3: When the PDCCH does not carry indication information for indicating paging scheduling, turn off the radio frequency component.
[0122] refer to Figure 7 For paging occasion 0 (i.e., the first paging cycle), by detecting the PDCCH, it is determined that the PDCCH does not carry the indication information for indicating the paging scheduling. After detecting the PDCCH, the terminal can turn off the RF component (i.e., Figure 7 Optionally, in the first paging cycle, PDSCH / DP / PS HWA is still in a closed state.
[0123] Optionally, at the start time unit of paging opportunity 1 (i.e., the second paging cycle), the RF component (i.e., Figure 7 RF ON in the first paging cycle) to obtain the RF signal in the second paging cycle. It can be understood that in the first paging cycle, from the time unit after detecting the PDCCH to the end time unit of paging opportunity 0, the RF component is in a closed state to save the power consumption of the RF component; at the start time unit of the second paging cycle, the terminal can restart the RF component to ensure that the RF signal in the second paging cycle is not lost.
[0124] Step 4: When the PDCCH carries indication information for indicating paging scheduling, PDSCH HWA is enabled.
[0125] The PDSCH HWA is used to obtain the paging message indicated by the paging scheduling, and the paging message is carried in the PDSCH.
[0126] refer to Figure 7For paging opportunity 1 (i.e., the second paging cycle), by detecting PDCCH HWA, it can be determined that PDCCH carries indication information of user paging scheduling. Based on this, BB turns on PDSCH HWA to facilitate detection of PDSCH. Among them, in the time unit when PDSCH HWA is turned on, DP / PS HWA remains turned off.
[0127] Optionally, in addition to being able to obtain a paging message to establish a connection with a network device, the detection result of PDSCH also includes the following two situations: PDSCH carries processing information related to the data plane; PDSCH carries processing information related to the protocol stack. Based on the above two situations, the terminal can start the DP / PS-associated hardware to start the corresponding interface processing. Among them, the interface processing includes: the processing corresponding to the DP, and / or the processing corresponding to the PS. Optionally, DP HWA is used to implement the processing corresponding to the DP, and PS HWA is used to implement the processing corresponding to the PS.
[0128] refer to Figure 7 After PDSCH HWA is turned on, BB can implement PDSCH detection to further detect paging messages. When detecting PDSCH, PDSCH also carries processing information related to the protocol stack, so BB turns on PSHWA (wakeup PS if necessary) to facilitate interface processing (PS processing) corresponding to PS.
[0129] In summary, in the paging detection method provided in the embodiment of the present application, whether to turn on the PDSCH HWA is determined according to the detection result of the PDCCH, so that the PDSCH HWA does not need to be kept turned on in real time, thereby achieving the purpose of saving power consumption.
[0130] contrast Figure 1 and Figure 7 In the paging detection method provided in the embodiment of the present application, in the starting unit of the first paging cycle, only PDCCH HWA needs to be turned on to realize PDCCH detection; and PDSCH / DP / PS HWA is in a closed state and does not need to be kept open all the time. Based on the large power consumption of PDSCH HWA, this will enable PDSCH HWA to be turned on when needed and turned off when not needed to reduce the large power consumption.
[0131] Furthermore, when PDSCH HWA is enabled, it is determined whether to enable DP / PS HWA according to the detection result of PDSCH to start the corresponding interface processing. This will enable DP / PS HWA to be enabled when needed and disabled when not needed, so as to further reduce power consumption.
[0132] In addition, when the PDCCH does not carry the indication information for indicating the paging scheduling, the terminal can further turn off the RF component, which will reduce the power consumption caused by RF reception by at least 50% compared to keeping the RF component always turned on. At the same time, the RF component is restarted at the start time unit of the next paging cycle. Based on this, the RF component is turned on or off according to different situations, which can further reduce the power consumption caused by RF reception and ensure that the terminal does not miss the RF signal.
[0133] In some embodiments, the terminal is in a standby state. When the terminal performs paging detection based on the standby state, the probability of detecting paging scheduling is 1%, and the probability of not detecting paging scheduling is 99%, that is, the probability of detecting paging scheduling through PDCCH is low. It can be understood that the paging detection method provided in the embodiment of the present application can relatively save 99% of the power consumption related to PDSCH.
