Description

Method and device for receiving signal
Technical Field
The present application relates to the field of communications, and more particularly, to a method and apparatus for signal reception.
Background
In the conventional scheme, a discontinuous reception (discontinuous reception, DRX) cycle is used for power saving of the terminal. Specifically, the network device configures a DRX cycle for the connected terminal, and only a period of time (which may be referred to as a duration timer (on duration timer)) within the DRX cycle detects data, and the other times do not detect data.
In order to reduce the power consumption of the terminal even further, a Wake Up Signal (WUS) is introduced, and the terminal determines whether to receive a physical downlink control channel (physical downlink control channel, PDCCH) during on duration timer according to WUS. In order to improve the reliability of the received data, an offset value (offset) is introduced, that is, the time interval between the moment of receiving WUS and the starting moment of on duration timer is set to a fixed value (also referred to as offset value), and the terminal performs measurement of the reference signal in the offset period and reports the measurement result. Thus, the terminal needs to enter on duration timer after the interval offset no matter whether or not the measurement of the reference signal is performed after WUS is received, resulting in a longer delay of signal transmission.
Disclosure of Invention
The application provides a signal receiving method and device, which can reduce the time delay of signal transmission.
In a first aspect, there is provided a method of signal reception, the method comprising: receiving a first signal at a first time, the first signal indicating receipt of a second signal within a duration timer within a first discontinuous reception, DRX, cycle; determining a first offset period according to the first signal, wherein the first offset period is a time offset between the first time and the starting time of the duration timer; the second signal is received within the duration timer.
The terminal receives the first signal at the first moment and determines the length of the first offset period according to the first signal, so that the terminal can determine the starting moment of the duration period timer according to the first offset period and the first moment and receive the second signal in the period of the duration period timer. That is, the offset value between the first time when the terminal receives the first signal and the starting time of the duration timer in the embodiment of the application is flexibly changed, compared with the offset value which is fixed in the traditional scheme, the embodiment of the application reduces the signal transmission delay, and correspondingly, reduces the duration of detecting the received signal by the terminal, namely reduces the power consumption of the terminal.
In some possible implementations, the method further includes: and determining the starting moment of the duration timer according to the first offset period and the first moment.
The terminal may determine a time of a time length of the first offset period after the first time as a starting time of the duration timer, and receive the second signal in a period of the duration timer, which reduces a signal transmission delay compared to a case where the offset value is fixed in a conventional scheme.
In some possible implementations, the method further includes: determining a third signal according to the first signal, wherein the third signal is a signal interfering with the first signal at a second moment; determining a second offset period according to the type of the third signal, wherein the second offset period is the time offset between the second moment and the first moment; the first time is determined based on the second offset period and the second time.
Under the condition that an interference signal exists at a second moment of preset transmission of a first signal, the moment of transmission of the first signal is shifted from the second moment to the first moment according to the type of the interference signal, so that the first signal is received at the first moment, signal interference is reduced, and communication efficiency is improved.
In some possible implementations, the first signal is further configured to indicate whether the first offset period is used for detecting a reference signal, wherein the determining the first offset period based on the first signal includes: the first signal indicates the first offset period to be used for detecting a reference signal, and the duration of the first offset period is determined to be a first duration; and when the first signal indicates that the first offset period is not used for detecting the reference signal, determining that the duration of the first offset period is a second duration, wherein the second duration is smaller than the first duration.
The first signal may indicate whether the first offset period is used for detecting the reference signal, if so, determining a duration of the first offset period as a first duration, and if not, determining a duration of the first offset period as a second duration, wherein the second duration is less than the first duration. That is, in the case that the terminal does not need to detect the reference signal in the first offset period, the duration of the first offset period may be set shorter, so that the signal transmission delay is further saved.
In some possible implementations, the first duration and the second duration satisfy: offset1 = offset2+ delta, delta is an integer, offset1 is the first duration, and offset2 is the second duration.
In some possible implementations, the delta is the same value as the duration of the measurement reference signal.
Under the condition that the first signal indicates that the first offset period does not need to carry out measurement of the reference signal, the duration of the first offset period does not need to consider the measurement time reserved for carrying out the reference signal, so that the duration of the first offset period is determined more accurately, the transmission delay caused by the fact that the first offset period is too long is avoided, and the transmission delay is reduced.
In some possible implementations, the starting time of the first DRX cycle is the same as the first time.
In some possible implementations, the starting time of the first DRX cycle is the same as the starting time of the duration timer within the first DRX cycle.
In some possible implementations, the method further includes: the period of the first signal is determined based on the DRX period.

In this case, the application program for executing the method of the embodiment of the present application and the application program for controlling the receiving end device to complete the action corresponding to the received data may be different application programs.
Fig. 1 is a schematic diagram of a communication system of the present application. The communication system in fig. 1 may include at least one terminal (e.g., terminal 10, terminal 20, terminal 30, terminal 40, terminal 50, and terminal 60) and a network device 70. The network device 70 is used to provide a communication service for a terminal and access the core network, and the terminal may access the network by searching for a synchronization signal, a broadcast signal, etc. transmitted by the network device 70, thereby performing communication with the network. The terminals 10, 20, 30, 40 and 60 in fig. 1 may perform uplink and downlink transmission with the network device 70. For example, the network device 70 may transmit downlink signals to the terminals 10, 20, 30, 40 and 60, or may receive uplink signals transmitted from the terminals 10, 20, 30, 40 and 60.
The terminals 40, 50 and 60 may be regarded as one communication system, and the terminals 60 may transmit downlink signals to the terminals 40 and 50 or may receive uplink signals transmitted from the terminals 40 and 50.
Fig. 2 shows a schematic diagram of another communication system of the present application. In the communication system of fig. 2, one or more network devices may serve one terminal, i.e. multiple network devices may perform data or signaling transmission with a certain terminal at the same time. For example, network device 10, network device 20, and network device 30 may communicate with the terminal at the same time.
In the conventional scheme, a discontinuous reception (Discontinuous Reception, DRX) cycle is used for power saving of the terminal. Specifically, the network device configures a DRX cycle for the terminal in the connected state, where only a period of time (may be referred to as a duration timer (on duration timer)) in the DRX cycle detects data, and other times do not detect data, as shown in fig. 3, where the starting time of the duration is the starting time of the DRX cycle, the detection data is performed in the duration, and other periods in the DRX cycle do not detect data.
In order to reduce the power consumption of the terminal even further, a Wake Up Signal (WUS) is introduced, and the terminal determines whether to receive a physical downlink control channel (physical downlink control channel, PDCCH) during on duration timer according to WUS. In order to improve the reliability of the received data, an offset value (offset) is introduced, i.e. the time interval between the moment when WUS is received and the starting moment of on duration timer is set to a fixed value (also called offset value), during which the terminal performs measurement of the Reference Signal (RS) and reports a measurement report (measurement report) of the measurement result. Thus, the terminal needs to enter on duration timer after an interval offset, whether or not measurement of the reference signal is performed after WUS is received, for example, as shown in fig. 4, the offset between WUS and the start time of the duration timer is a fixed value, resulting in a longer delay of signal transmission.
Fig. 5 shows a schematic flow chart of a method of signal reception according to an embodiment of the present application.
It should be understood that the execution body of the embodiment of the present application may be a terminal, and the corresponding transmitting end may be a network device.
501, the terminal receives a first signal at a first time, the first signal being used to indicate that a second signal is received within a duration timer within a first DRX cycle. Accordingly, the network device transmits the first signal at the first time.
Specifically, in the scenario where the terminal performs signal detection according to the DRX cycle, signal (i.e., second signal) detection is performed during on duration timer operation in the DRX cycle, and second signal detection is not performed during other periods in the DRX cycle. The network device may send a signal (i.e., a first signal) at a time (i.e., a first time) before the duration timer in a certain period (i.e., a first DRX cycle) to indicate that the terminal needs to detect the second signal in the duration timer.
Note that the time length of on duration timer in one DRX cycle is fixed, and the time lengths of on duration timer in different DRX cycles may be the same or different, which is not limited in this application.
Alternatively, the first time may be fixed or may be flexible (e.g., the first time may be configured by the network device).
Alternatively, the terminal and the network device may agree in advance to transmit the first signal at a certain time (for example, a second time), and if there are other interference signals in addition to the first signal at the second time, the terminal and the network device may perform the offset (i.e., the second offset period) of the transmission time according to the interference signals, and transmit the first signal at the time (i.e., the first time) after the offset. In other words, the first time instant may be an advance or a retard of the second time instant based on network device configured or fixed POWSS transmissions.
For example, the plurality of interference signals are uplink signals, the network device may determine a first time domain position after a position where the uplink signals end as a first time instant, and send the first signal at the first time instant, and correspondingly, the terminal receives the first signal at the first time instant.
For another example, the plurality of interference signals are downlink signals, and the network device may determine a first time domain position after a position where the downlink signals end as a first time, and send the first signal at the first time, and correspondingly, the terminal receives the first signal at the first time.
The interference signal may be the same as the first signal or may be different from the first signal, and this is not limited in this application.
It should be noted that the time length of the second offset period may be in units of at least one of a frame, a subframe, a slot, or a symbol.
Alternatively, the length of the second offset period may be any one integer of 1,2, …, 19.
For example, when the interfering signal is SSB, the first time of transmitting the POWSS may be offset from the second time by 8 or 4 symbols or a half frame, i.e. a time length of 5ms, when the POWSS collides with the SSB at the second time.
Alternatively, the first signal may be a signal that only indicates that the terminal needs to perform signal detection during on duration timer operation, e.g., if the terminal receives the first signal, the terminal needs to perform signal detection during on duration timer operation; if the terminal does not receive the first signal, the terminal need not perform signal detection during on duration timer operation.
Optionally, the first signal may also indicate whether the terminal needs to perform signal detection during on duration timer operation, for example, a first value of at least one bit in the first signal may be used to indicate that signal detection is required during on duration timer operation, and a second value of at least one bit in the first signal may be used to indicate that signal detection is not required during on duration timer operation.
It should be noted that the first signal may also indicate that the terminal does not need to perform signal detection during on duration timer operation. That is, the terminal does not need to perform signal detection during on duration timer operation when receiving the first signal, and does need to perform signal detection during on duration timer operation when not receiving the first signal.
Alternatively, the first signal may be WUS, a sleep signal (go to sleep signal, GTS), or a power saving signal (power saving signal, POWSS).
Specifically, the GTS may be a sequence signal, a data signal, or a signaling signal. Wherein the data signal may be PDSCH. The signaling signal may be downlink control information, MAC-CE, or RRC signaling.
It will be appreciated that which of the first signals is in particular may be determined by the network device and the particular form of the first signals indicated by the indication information. The indication information may be sent separately from the first signal, or the indication information may be carried in the first signal, which is not limited in this application.
Alternatively, the second signal may be scheduling information. Specifically, the physical downlink control channel (physical downlink control channel, PDCCH) may be used.
502, the terminal determines a first offset period according to the first signal, where the first offset period is a time offset between the first time and a starting time of the duration timer.
Specifically, the length of the first offset period may be related to the first signal, and the terminal may determine the length of the first offset period according to the first signal. The terminal can then determine the starting instant of the duration timer based on the first offset period and the first instant. That is, the offset value between the first moment of transmitting the POWSS and the drx-onduration timer is flexibly changed, and compared with the offset value in the conventional scheme, the embodiment of the present application reduces the signal transmission delay, and correspondingly, reduces the duration of detecting the received signal by the terminal, that is, reduces the power consumption of the terminal.
It should be noted that, the time length of the first offset period may be in units of at least one of a frame, a subframe, a slot, or a symbol.
It should be understood that, in the case where the first time is fixed, if the first offset period changes, the starting time of the drx-onduration timer also changes.
Alternatively, the terminal may receive the reference signal during the first offset period and report the measurement result of measuring the reference signal to the network device.
Alternatively, step 502 may specifically be determining the first offset period according to the type of the first signal.
Specifically, the type of the first signal may have a mapping relationship with the length of the first offset period, so that the terminal may accurately determine the length of the corresponding first offset period according to the type of the first signal.
For example, the length of the first offset period may be any one integer of 1,2, …, 19. The unit may be a symbol, slot, subframe, field or frame.
Optionally, the type of the first signal may be further more specifically classified into PDCCH, reference signal, system information, and data signal. The reference signal may be at least one of a channel state information reference signal (channel state information reference signal, CSI-RS), a phase-tracking reference signal (phase-tracking reference signals, PTRS), a Synchronization Signal Block (SSB), and a demodulation reference signal (demodulation reference signals, DMRS). The at least one type of first signal may have a mapping relationship with the length of the first offset period, so as to more accurately determine the time length of the corresponding first offset period.
Specifically, the network device may configure values of a plurality of first offset periods (offset), different types of first signals may have a mapping relationship with different offset periods, and the network device determines a corresponding offset period according to a type of a certain signal.
Optionally, the terminal may further determine a time length of the first offset period according to a type of the reference signal transmitted in the first offset period.
Specifically, the types of different reference signals may have a mapping relationship with different first offset periods, so that the terminal may determine the duration of the first offset period according to the type of the reference signal.
It should be understood that the types of the different reference signals may be distinguished according to the duration of the continuous transmission of the reference signals, or may be distinguished according to the function of the reference signals, which is not limited in this application.
Optionally, the first signal may be further used to indicate whether the first offset period is performing reference signal measurement or synchronization, so step 502 may specifically be determining that the first offset period is a first duration when the first signal indicates that the first offset period is performing reference signal measurement or synchronization; the first offset period is determined to be a second duration when the first signal indicates that the first offset period does not make reference signal measurements. Wherein the first duration may be greater than the second duration. For example, if it is indicated that measurement of the reference signal is required, a longer first offset period is employed; if the measurement or synchronization of the reference signal is not required, a shorter first offset period is adopted, so that the delay of signal transmission is reduced.
It should be understood that the terminal may perform reference signal measurement by parsing the received reference signal and reporting a measurement result obtained by parsing the reference signal.
In other words, the offset value between the transmission time of the POWSS and the start time of the drx-onduration timer, the transmission time of the POWSS, and the start time of the drx-onduration timer may all be varied. One way of varying is to determine based on the presence or absence of a POWSS or to vary the offset value of the POWSS and the drx-onduration timer as indicated by the POWSS or to vary based on the presence of a Pre-wake-up window. The first variation is that the position of the POWSS is fixed, the starting position or offset position of the DRX cycle is variable with respect to the position of the POWSS, the starting time of the DRX-onduration timer is variable with respect to the position of the POWSS, and there may be no offset between the starting position of the DRX cycle and the starting position of the DRX-onduration timer. The second way of variation is that the position of the POWSS is fixed, the starting position of the DRX cycle is fixed, the relative offset of the starting time of the DRX-onduration timer from the position of the POWSS is variable or the starting time of the DRX-onduration timer from the starting position of the DRX cycle is relatively variable. The pouss or RRC signaling or system information signaling or MAC-CE signaling or DCI signaling may refer to the start time position of the drx-onduration timer. The starting time position may be based on a symbol, subframe, slot, frame or the like. The starting time may have a value of 0 to T2, where T2 represents the number of time units within the duration of DRX-onduration timer or the number of time units within the duration of DRX cycle. The ending time position of the drx-onduration timer may not change, and may also delay or advance by the same time value along with the change value of the starting position. Thereby reducing power consumption. When the start time of the DRX-onduration timer is offset with respect to the start position of the DRX cycle period or the position of the POWSS, the offset may be offset3. The network device may also directly configure the start position t5 of the drx-onduration timer, and may configure one or more values of t5 through RRC signaling, MAC-CE signaling, DCI signaling, or system information. For example, K2 values, and the reuse of the pouss signal indicates which of these K2 values the starting position of the drx-onduration timer uses. For example, K2 may be 2.
Optionally, the position of the first signal may be in the DRX cycle period in which the indicated DRX-onduration timer is located, or may be in K3 DRX cycle periods before the DRX cycle period in which the indicated DRX-onduration timer is located, where the value of K3 may be any one of 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16 values.
Optionally, the first signal may also be used to indicate whether the first offset period is used for synchronization, so step 502 may specifically be to determine that the first offset period is a first duration when the first signal indicates that the first offset period is used for synchronization; and determining the first offset period as a second duration when the first signal indicates that the first offset period is not used for synchronization. Wherein the first duration may be greater than the second duration.
It should be understood that the synchronization may be either a fine synchronization or a coarse synchronization, which is not limited in this application.
Alternatively, the first signal may indicate a duration of the first offset period. The duration of the first offset period indicated by the first signal may be different in different scenarios. For example, the first offset period may be a first period of time or a second period of time, and the first period of time and the second period of time are different.
Optionally, the first time period offset1 and the second time period offset2 satisfy: offset1 = offset2+ delta, delta being an integer. In other words, offset1 may be greater than offset2.
It should be appreciated that the value of offset1 or offset2 or delta or offset3 may be any integer or integers of 1,2, …, 20. The unit may be a symbol, slot, subframe, field or frame.
It should be noted that the delta may be configured by a network device, and the network device may configure only one delta value, or may configure multiple delta values. In the case where the network device configures a plurality of delta values, the terminal may select an appropriate delta according to the difference of offset 1.
Alternatively, the delta may be the same value as the duration of the measurement reference signal.
In particular, the delta may be the same length of time as the pre-wakeup window (pre wake up window). Or the delta may be the same as the sum of the length of time of measurement report window and the length of time of pre wake up window, i.e., the delta may be the same length of time from the start position of pre wake up window to the end position of measurement report window.
Note that pre wake up window may represent a time period for the terminal device to measure the reference signal, may represent that the terminal device may perform signal measurement within Pre wakeup window before the onduration timer is started, and may also be referred to as a signal measurement window.
It should be understood that the reference signal may be a CSI-RS, may be an SSB, may be a DMRS of a data signal, may be a power saving signal, and may be a TRS.
It should also be appreciated that the length of Pre wake up window may be in symbols, slots, subframes, or fields. Where the subframes may be milliseconds. The unit is that the symbol and the time slot can have more accurate time length, so as to reduce the power consumption of the terminal equipment, and if the unit is a subframe or a field, the unit is that the data bit can be shorter, so that the signaling overhead of configuration is reduced. The value of the length of Pre wake up window may be some or all of 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32.
Note that Pre wake up window may not be present, and directly indicates the length of time occupied by the measurement signal.
Alternatively, the period of Pre wake up window may be related to the C-DRX period or may be configured separately. The presence of Pre wake up window may be dependent upon an indication of the power saving signal. The period value of Pre wake up window may be a multiple of the C-DRX period, the multiple may be a value of some or all of 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32, and the multiple value may be set according to the length of the DRX period.
Optionally, on the basis of the multiple, the presence or absence of Pre wake up window or the presence or absence of the measurement signal is based on an indication of the power saving signal. The period value of Pre wake up window may be a value of some or all of 1,2,3,4,5,6,7,8,9,10,11,12,13, 14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29, 30,31, 32.
Alternatively, the location of Pre wake up window can be configured separately and the configurable value can be any one of 0 to T-1, where T represents a period of Pre wake up window. The location of Pre wake up window may also be configured with respect to the location of power saving signal or with respect to the starting location of the DRX-cycle or DRX-onduration timer, i.e. with respect to one or more of these locations, an offset value may be some or all of the values 1,2,3,4,5,6,7,8,9,10,11,12,13, 14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29, 30,31, 32. The units may be one or more of symbols, slots, subframes, or fields. When Pre wake up window is absent, pre wake up window may be replaced with the duration of the measurement reference signal, or the time position of the measurement reference signal.
It should be appreciated that the period of Pre wake up window may be in symbols, slots, subframes, frames, or fields. Optionally, a start time of the first DRX cycle (C-DRX cycle) is the same as a time of receiving the first signal.
Specifically, the starting time of the first DRX cycle in the embodiment of the present application may be the same as the time of receiving the first signal. For example, as shown in fig. 6.
It should be understood that the first DRX cycle may be any one of the DRX cycles, and one of them is described as an example in this application, but the application is not limited thereto.
Optionally, the starting time of the first DRX cycle is the same as the starting time of the duration timer within the first DRX cycle, e.g., as shown in fig. 4.
It should be noted that, the relative position between the starting time of the first DRX cycle and the starting time of the duration timer in the first DRX cycle may also have an offset, and the offset may be fixed or may be flexibly changed, which is not limited in this application.
Alternatively, the starting time of the first DRX cycle may be the same as the starting position of the measurement report window.
The terminal receives the second signal within the duration timer 503.
Specifically, the terminal receives the first signal at the first time, and determines the length of the first offset period according to the first signal, so that the terminal can determine the starting time of the duration timer according to the first offset period and the first time, and receive the second signal in the period of the duration timer. That is, the offset value between the first time when the terminal receives the first signal and the starting time of the duration timer in the embodiment of the application is flexibly changed, compared with the offset value which is fixed in the traditional scheme, the embodiment of the application reduces the signal transmission delay, and correspondingly, reduces the duration of detecting the received signal by the terminal, namely reduces the power consumption of the terminal.
It should be noted that, when the second signal is received in the duration timer, the terminal may further restart an activation timer (DRX-activity timer).
It should be understood that the duration of the duration timer may be specified by a protocol, may be configured by a network device, or may be agreed in advance by a terminal and the network device, which is not limited in this application.
Alternatively, the network device may also send the first signal periodically (a second period), and the duration of the second period may be related to the duration of the first DRX period.
Specifically, the terminal may determine the duration of the second period according to the duration of the first DRX period. For example, the second period may be N times or 1/N the length of the first period. For example, N is an integer of 1,2, …, 16.
It should be understood that the specific value of N may be configured by a network device, or may be predetermined in advance, which is not limited in the embodiment of the present application.
It should be noted that, when the first period is 1/N of the second period, the network device does not detect the first signal when the duration timer expires or the first signal may also indicate that the terminal device enters into sleep, but the first signal before the start time of the duration timer is to be detected, so the network device is to configure or provision the index or position of the first signal to be detected in the period of sleep of the terminal in the first period, for example, the network device may configure or provision the last K first signal terminal to be detected in the first period by the network device, where the value of K is any one of 1,2,3,4,5,6,7, and 8. The smaller the value of K, the less power consumption the terminal device consumes, and therefore the power consumption is minimal when the value of K is 1 or 0. The terminal detects the POWSS at the transmitted position of the POWSS, and these POWSSs may also be signals indicating that the terminal is asleep. Therefore, when designing the first signal, for example, the terminal device may perform integrated design on WUS and GTS indicating to perform PDCCH detection, that is, the first signal has a function of indicating to perform PDCCH detection and a function of indicating to the terminal to enter a sleep period, for example, the first signal includes WUS and GTS.
Fig. 7 shows a schematic flow chart of another signal receiving method of the present application.
Therefore, when the network device configures the offset of the POWSS, the network device can be configured according to the cycle of the POWSS, and one configuration method is 0-T-1. Where T represents the period of the POWSS. The T units may be symbol-based, slot-based, subframe-based, field-based, or frame-based.
When the cycle of the POWSS is 1/N of the DRX-cycle, the invention provides a WUS and GTS integrated design. When the network device detects the POWSS, in the case of a DRX-inactive timer timeout or in a time after the PSS indicates that the terminal device goes to sleep, the network device does not detect the POWSS, but the POWSS before the DRX-onduration timer start time is to be detected, so the network device is to configure or protocol specify a POWSS index or position to be detected in a period of time when the terminal is to sleep in the DRX-cycle, for example, the network device may configure or protocol specify that the K4 th POWSS terminal device in the DRX-cycle is to be detected, and the value of K4 is any one of 1,2,3,4,5,6,7, 8. The smaller the value of K4, the less power consumption the terminal device consumes, and therefore the power consumption is minimal when the value of K4 is 1 or 0. The terminal device detects the POWSS at the time of sleep in the DRX cycle, which may be referred to as a wake signal, and detects the POWSS at the position of transmission of the POWSS in the DRX-inactive timer or in the DRX-onduration timer, which may be signals indicating that the terminal is asleep. Therefore, the terminal equipment can be integrally designed when designing the POWSS.
Optionally, when the network device configures short DRX (short DRX), and the pouss indicates that the terminal device enters sleep without timeout of the DRX-inactive timer, the DRX-inactive timer may continue to count, so that the terminal device starts or restarts the DRX-short cycle timer when the DRX-inactive timer is timeout. The terminal device may not perform timing of the drx-inactive timer, and the network device and the terminal device may instruct the drx-short cycletimer to start or restart at a timing when the drx-inactive timer ends, i.e. start or restart the drx-short cycletimer at a timing when the drx-inactive timer ends as instructed by the pouss.
Unless otherwise specified, the terms in the embodiments of the present application that are the same as those in the embodiments shown in fig. 5 and 6 are the same.
The terminal and the network device may agree in advance on two times of transmission of the POWSS, for example, time t1 and time t3 in fig. 7. The terminal receives WUS at the time t1, if the WUS is not received, the terminal continues to receive the WUS at the time t3, and receives PDCCH in a duration timer started at the time t4, wherein the first offset time periods at the time t3 and the time t4 are offset 2; if the terminal receives WUS at time t1, the terminal detects PDCCH in a duration timer from time t2, wherein the time offset between time t1 and time t2 is offset 1.
The offset (offset) 1 and the offset (offset) 2 are fixed values, respectively, and the offset1 and the offset2 are different.
It should be understood that the offset1 may be used for measuring reference signals and the offset2 may be used for measuring reference signals, which is not limited in this application.
Optionally, the first time period offset1 and the second time period offset2 satisfy: offset1 = offset2+ delta, delta being an integer. In other words, offset1 may be greater than offset2.
It should be appreciated that the offset1 may be any integer of 1,2, …, 20.
It should be noted that the delta may be configured by a network device, and the network device may configure only one delta value, or may configure multiple delta values. In the case where the network device configures a plurality of delta values, the terminal may select an appropriate delta according to the difference of offset 1.
Alternatively, the delta may be the same value as the duration of the measurement reference signal.
In particular, the delta may be the same length of time as pre wake up window. Or the delta may be the same as the sum of the length of time of measurement report window and the length of time of pre wake up window. It should be understood that the starting position of the DRX cycle in the embodiment of the present application may be the same as the starting position of the DRX cycle in the embodiment shown in fig. 5 or fig. 6.
The method of signal reception according to the embodiment of the present application is described in detail above, and the apparatus of signal reception according to the embodiment of the present application will be described below.

and when the first signal indicates that the first offset period is not used for detecting the reference signal, determining that the duration of the first offset period is a second duration, wherein the second duration is smaller than the first duration.
Optionally, the first duration and the second duration satisfy:
offset1 = offset2+ delta, delta is an integer, offset1 is the first duration, and offset2 is the second duration.
Optionally, the delta is the same value as the duration of the measurement reference signal.
Optionally, the starting time of the first DRX cycle is the same as the first time.

The apparatus may employ a hardware architecture as shown in fig. 9. The apparatus may include a processor 910 and a transceiver 920, and optionally, a memory 930, where the processor 910, transceiver 920, and memory 930 communicate with each other through an internal connection path. The related functions performed by the processing module 620 in fig. 6 may be performed by the processor 910, and the related functions performed by the transceiver module 610 may be performed by the processor 910 controlling the transceiver 920.
Alternatively, the processor 910 may be a general purpose central processing unit (central processing unit, CPU), microprocessor, application-specific integrated circuit (ASIC), special purpose processor, or one or more integrated circuits configured to perform the techniques of embodiments of the present application. In the alternative, a processor may refer to one or more devices, circuits, and/or processing cores for processing data (e.g., computer program instructions). For example, a baseband processor, or a central processing unit. The baseband processor may be used to process communication protocols and communication data, and the central processor may be used to control devices (e.g., base stations, terminals, or chips, etc.), execute software programs, and process data from the software programs.
Alternatively, the processor 910 may include one or more processors, including, for example, one or more central processing units (central processing unit, CPU), which in the case of a CPU, may be a single-core CPU or a multi-core CPU.
The transceiver 920 is used to transmit and receive data and/or signals, and to receive data and/or signals. The transceiver may include a transmitter for transmitting data and/or signals and a receiver for receiving data and/or signals.
The memory 930 includes, but is not limited to, random access memory (random access memory, RAM), read-only memory (ROM), erasable programmable memory (erasable programmable read only memory, EPROM), and compact disc-read only memory (compact disc read, CD-ROM), the memory 930 configured to store instructions and data.
The memory 930 is used for storing program codes and data of the terminal and may be a separate device or integrated in the processor 910.
In particular, the processor 910 is configured to control the transceiver to communicate information with a network device. Reference may be made specifically to the description of the method embodiments, and no further description is given here.
It will be appreciated that fig. 9 shows only a simplified design of a device for signal reception. In practical applications, the apparatus may further include other necessary elements, including but not limited to any number of transceivers, processors, controllers, memories, etc., and all terminals capable of implementing the present application are within the scope of protection of the present application.
In one possible design, the device 900 may be a chip, such as a communication chip, for example, that may be used in a terminal to implement the functions associated with the processor 910 in the terminal. The chip can be a field programmable gate array for realizing related functions, an application specific integrated chip, a system chip, a central processing unit, a network processor, a digital signal processing circuit, a microcontroller, a programmable controller or other integrated chips. In the chip, one or more memories may optionally be included for storing program code that, when executed, causes the processor to perform the corresponding functions.

An output device communicates with the processor 910 and can display information in a variety of ways. For example, the output device may be a liquid crystal display (liquid crystal display, LCD), a light emitting diode (light emitting diode, LED) display device, a Cathode Ray Tube (CRT) display device, or a projector (projector), or the like. The input device(s) are in communication with the processor 601 and may receive user input in a variety of ways. For example, the input device may be a mouse, a keyboard, a touch screen device, a sensing device, or the like.
Alternatively, when the device in this embodiment is a terminal, fig. 10 shows a simplified schematic structure of the terminal. The terminal is illustrated as a mobile phone in fig. 10 for easy understanding and convenient illustration. As shown in fig. 10, the terminal includes a processor, a memory, a radio frequency circuit, an antenna, and an input-output device. The processor is mainly used for processing communication protocols and communication data, controlling the terminal, executing software programs, processing data of the software programs and the like. The memory is mainly used for storing software programs and data. The radio frequency circuit is mainly used for converting a baseband signal and a radio frequency signal and processing the radio frequency signal. The antenna is mainly used for receiving and transmitting radio frequency signals in the form of electromagnetic waves. Input and output devices, such as touch screens, display screens, keyboards, etc., are mainly used for receiving data input by a user and outputting data to the user. It should be noted that some kinds of terminals may not have an input/output device.
When data need to be sent, the processor carries out baseband processing on the data to be sent and then outputs a baseband signal to the radio frequency circuit, and the radio frequency circuit carries out radio frequency processing on the baseband signal and then sends the radio frequency signal outwards in the form of electromagnetic waves through the antenna. When data is sent to the terminal, the radio frequency circuit receives a radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor, and the processor converts the baseband signal into data and processes the data. For ease of illustration, only one memory and processor is shown in fig. 10. In an actual end product, there may be one or more processors and one or more memories. The memory may also be referred to as a storage medium or storage device, etc. The memory may be provided separately from the processor or may be integrated with the processor, which is not limited by the embodiments of the present application.

The transceiver unit may also be referred to as a transceiver, transceiver circuitry, or the like. The receiving unit may also be referred to as a receiver, or receiving circuit, among others.

For example, in one implementation, the processing unit 1020 is configured to perform the operations in step 502 in fig. 5, and/or the processing unit 1020 is further configured to perform other processing steps on the terminal side in the embodiments of the present application. The transceiver 1010 is configured to perform the transceiving operations in step 501 and/or step 503 in fig. 5, and/or the transceiver 1010 is further configured to perform other transceiving steps on the terminal side in the embodiment of the present application.
When the device is a chip, the chip comprises a transceiver unit and a processing unit. The receiving and transmitting unit can be an input and output circuit and a communication interface; the processing unit is an integrated processor or microprocessor or integrated circuit on the chip.
Alternatively, when the apparatus is a terminal, reference may also be made to the device shown in fig. 11. As an example, the device may perform functions similar to the processor 1010 of fig. 10. In fig. 11, the apparatus includes a processor 1101, a transmission data processor 1103, and a reception data processor 1105. The processing modules 610 and 1320 in the above embodiments may be the processor 1101 in fig. 11, and perform corresponding functions. The transceiver module 620 and the transceiver module 610 in the above embodiments may be the transmit data processor 1103 and the receive data processor 1105 in fig. 11. Although a channel encoder, a channel decoder are shown in fig. 11, it is to be understood that these modules are not limiting illustrations of the present embodiment, but are merely schematic.
Fig. 12 shows another form of the present embodiment. The processing device 1200 includes a modulation subsystem, a central processing subsystem, a peripheral subsystem, and the like. The communication device in this embodiment may act as a modulation subsystem therein. In particular, the modulation subsystem may include a processor 1203, an interface 1204.
