Description

Detection method, transmission method, terminal and network side equipment of advanced indication signal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method for detecting an advance indicator, a method for transmitting an advance indicator, a terminal, and a network device.

Background

At present, in order to save power consumption of a blind Paging (Paging) signal or a PDCCH (Physical Downlink Control Channel) in a DRX (Discontinuous Reception) situation or other situations, a concept of a wake-up signal (WUS) and a sleep signal (GO-to-sleep signal) is proposed, wherein the wake-up signal and the sleep signal may be collectively referred to as an advance indication signal or a power saving signal.

In each DRX cycle of an RRC (Radio Resource Control) idle state or an RRC connected state, or in an RRC connected state (DRX off), before a terminal blindly detects a paging signal or a PDCCH, a base station first transmits a wake-up signal to the terminal, and the terminal wakes up at a corresponding time to detect the wake-up signal. If the terminal detects the wake-up signal, the terminal blindly detects a paging signal or a PDCCH; otherwise, the terminal does not blindly detect the Paging signal or PDCCH (continue to sleep). Wherein detecting the wake-up signal is less complex and more power efficient than blindly detecting the paging signal or the PDCCH.

In each DRX cycle of the RRC idle state or the RRC connected state, the base station first transmits a sleep signal to the terminal before the terminal blindly detects a paging signal or a PDCCH, and the terminal wakes up at a corresponding time to detect the sleep signal. If the terminal detects the sleep signal, the terminal does not blindly detect the paging signal or the PDCCH (continuously dormancy); otherwise, the terminal blindly detects the paging signal or PDCCH (waking up). Wherein detecting the sleep signal is less complex and more power efficient than blindly detecting the paging signal or the PDCCH.

In order to enhance coverage performance, both the advance indication signal and the PDCCH may support repeated transmission. The maximum repetition times of the advanced indication signal and the maximum repetition times of the PDCCH of a cell or a carrier are required to meet the limit coverage capability of the cell or the carrier; the size of the information quantity transmitted by the advanced indication signal and the PDCCH is different, so the maximum repetition times of the advanced indication signal and the PDCCH are also different; the amount of information transmitted by the PDCCH is greater than the amount of information transmitted by the advance indication signal, and thus the PDCCH maximum number of repetitions is greater than the maximum number of repetitions of the advance indication signal.

However, how the terminal determines the start time of the early indication signal is not specified or defined at present, and particularly, in the case that a subframe in which the early indication signal is transmitted collides with a subframe in which a synchronization signal or a broadcast signal is located, and in the case that a part of subframes (such as uplink subframes) of the time division duplex system cannot be used for transmitting the early indication signal, the terminal cannot accurately determine the transmission time, particularly the transmission start time, of the early indication signal.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

Embodiments of the present invention are described below with reference to the accompanying drawings. The detection method, the transmission method, the terminal and the network side equipment of the advanced indication signal provided by the embodiment of the invention can be applied to a wireless communication system. The wireless communication system may be a 5G system, an Evolved Long Term Evolution (lte) system, or a subsequent lte communication system. Referring to fig. 1, an architecture diagram of a wireless communication system according to an embodiment of the present invention is shown. As shown in fig. 1, the wireless communication system may include: the network side device 10 and a terminal (terminal may also be referred to as a user side device), for example, the terminal is denoted as UE11, and the UE11 may be connected to the network side device 10. In practical applications, the connections between the above devices may be wireless connections, and fig. 1 illustrates the connections between the devices by solid lines for convenience and convenience in visual representation.

It should be noted that the communication system may include a plurality of UEs, and the network side device may communicate (transmit signaling or transmit data) with the plurality of UEs.

The network side device 10 provided in the embodiment of the present invention may be a base station, which may be a commonly used base station, an evolved node base station (eNB), or a network side device in a 5G system (for example, a next generation base station (gNB), a Transmission and Reception Point (TRP), or a cell) and other devices.

The terminal provided by the embodiment of the invention can be a Mobile phone, a tablet Computer, a notebook Computer, an Ultra-Mobile Personal Computer (UMPC), a netbook or a Personal Digital Assistant (PDA) and the like.

As shown in fig. 2, the method for detecting an early indication signal, applied to a terminal, includes:

step 201, a start time, a first time length and a time gap of a paging occasion PO corresponding to the advanced indication signal are obtained.

Preferably, the start time of the paging occasion PO corresponding to the advanced indication signal may specifically be the start time of the PO in the first paging window corresponding to the advanced indication signal.

In this step, the early indication signal is used to indicate whether the terminal performs blind detection on the paging signal. The early indication signal includes: a wake-up signal (WUS) and/or a sleep signal (GO-to-sleep signal). For example, when the terminal receives the wake-up signal, the terminal wakes up to perform blind detection on the paging signal, otherwise, the terminal continues to sleep. For another example, if the terminal receives the sleep signal, the terminal continues to sleep, otherwise, the terminal wakes up to perform blind detection on the paging signal.

Preferably, the first time length is associated with a maximum duration of the early indication signal, or the first time length is associated with a maximum number of repetitions of a physical downlink control channel PDCCH. Wherein, the maximum duration of the advanced indication signal is the duration corresponding to the maximum repetition number of the advanced indication signal of the serving cell or the carrier of the terminal; the maximum repetition times of the PDCCH is specifically as follows: a maximum number of repetitions of a PDCCH of a serving cell or carrier of the terminal.

Further, the time gap mentioned in this step is specifically a time length, and the time gap is a time gap between an end time of the first time length and a start time of the paging occasion PO, or the time gap is a time gap between an end time of the maximum duration of the advance indication signal and a start time of the paging occasion PO.

The end time of the first time length may be the same as or different from the end time of the maximum duration of the advance indication signal.

Step 202, determining a start time and an end time of the first time length according to the start time of the paging occasion PO, the time gap, and the first time length.

In this step, the specific location of the first time length and the time gap needs to be further determined according to the starting time of the paging occasion PO, that is, the location of the first time length is determined by determining the starting time and the ending time of the first time length, and this location may be referred to as a relative location of the first time length with respect to the starting time of the paging occasion PO, or may be referred to as an absolute location of the first time length (in a case that the starting time of the paging occasion PO is an absolute time).

Step 203, detecting the early indication signal on at least one target subframe between the starting time and the ending time of the first time length;

the at least one target subframe mentioned in this step includes a subframe where a start time of the first time length is located, a subframe where an end time of the first time length is located, and a subframe between the start time and the end time of the first time length. Preferably, the terminal detects the advance indication signal in sequence from the subframe where the start time of the first time length is located, when the subframe where the start time of the first time length is located is unoccupied or the subframe where the start time of the first time length is located is a downlink subframe.

Bearing the above example, in the above embodiment of the present invention, the method further includes:

and under the condition that the target subframe is a non-downlink subframe or the target subframe is occupied, the method continues to the next downlink subframe which is not occupied to detect the early indication signal.

Preferably, the non-downlink subframe specifically includes: an uplink subframe and/or a special subframe; the special subframe may be used for uplink transmission or downlink transmission, for example, 6 symbols in the special subframe are used for uplink transmission, and the remaining symbols are used for downlink transmission. The special subframe may or may not be used for transmitting the advance indication signal.

It should be noted that the downlink subframe that is followed will not exceed the subframe where the end time of the first time length is located.

For example, the early indication signal is detected sequentially from the start time of the first time length or from the start time of the maximum duration of the early indication signal, and if the current target subframe is an uplink subframe, the current target subframe is delayed to the next valid downlink subframe to detect the early indication signal.

For another example, the early indication signals are sequentially detected from the starting time of the first time length or the starting time of the maximum duration of the early indication signals, and if the current subframe is occupied, the current subframe is extended to the next unoccupied downlink subframe to detect the early indication signals.

Further, in the above embodiment of the present invention, the method further includes:

determining that the target subframe is occupied if the target subframe is occupied by a synchronization signal, a broadcast channel, or a system information block, SIB 1; or, in case the target-subframe is occupied by a synchronization signal, a broadcast channel, a system information block SIB1 or other system message, determining that the target-subframe is occupied. In other words, when the target-subframe is a subframe in which at least one of a synchronization signal, a broadcast channel, a system information block SIB1, and other system messages are located, the target-subframe is occupied.

For a narrowband Internet of Things (NB-IoT) system, the above synchronization signals correspond to: NPSS (narrowband primary Synchronization Signal), NSSS (narrowband secondary Synchronization Signal), NPBCH (narrowband physical Broadcast Channel) corresponding to a Broadcast Channel, SIB1-NB (narrowband SIB1) corresponding to a System Information block SIB1, SI (System Information ) corresponding to other System messages and other SIs (System Information) except SIB 1-NB;

for an enhanced Machine Type Communication (eMTC) system, determining that the target subframe is occupied if the target subframe is occupied by a system information block (SIB 1-BR);

further, in the foregoing embodiment of the present invention, the step of acquiring the time slot in step 201 includes:

acquiring the predefined time gap; alternatively, the first and second electrodes may be,

receiving a system message from a network side device, wherein the system message carries an indication domain of the time gap; alternatively, the first and second electrodes may be,

the terminal indirectly obtains the time gap through other parameters; the other parameters may be some parameters sent by the network side device, or some parameters acquired or collected by the terminal itself, and again, are not specifically limited. The time gap is related to the processing delay capability of the terminal.

Further, in the foregoing embodiment of the present invention, step 202 includes:

determining the ending time of the first time length according to the starting time of the PO at the paging occasion and the time gap;

and determining the starting time of the first time length according to the ending time of the first time length and the first time length.

Preferably, the determining the ending time of the first time length according to the starting time of the paging occasion PO and the time gap includes:

determining the end time of the first time length according to a first formula; wherein the first formula is: t3 ═ T4-L1;

wherein T3 is the end time of the first length of time; t4 is the starting time of the paging occasion PO; l1 is the time gap.

Preferably, the determining the starting time of the first time length according to the ending time of the first time length and the first time length includes:

determining the starting time of the first time length according to a second formula; wherein the second formula is: t1 ═ T3-L2;

wherein T1 is the starting time of the first time length; t3 is the end time of the first length of time; l2 is the first length of time.

It should be noted that, in the above embodiment of the present invention, the starting time of the paging occasion PO is the ending time of the time gap, and the starting time of the time gap is the ending time of the first time length; in short, the first time length, the time gap and the paging occasion PO are consecutive in the time domain.

Further, in the above embodiment of the present invention, the step of obtaining the first time length in step 202 includes:

determining the first time length according to the maximum repetition times of the PDCCH and a first reduction factor; wherein the first reduction factor is associated with a proportion of the target subframe that is occupied; preferentially, the occupied ratio of the target subframe is specifically as follows: a proportion of the target-subframe occupied by at least one of a synchronization signal, a broadcast channel, a SIB1, and other system messages.

Preferably, the first reduction factor may be predefined or may be signaled via SIB. Correspondingly, the method further comprises the following steps:

obtaining the predefined first reduction factor; alternatively, the first and second electrodes may be,

and receiving a system message from network side equipment, wherein the system message carries the indication domain of the first conversion factor.

In a specific embodiment of the present invention, a value of the first reduction factor is associated with a maximum number of repetitions of the PDCCH;

wherein, the values of the first reduction factors corresponding to different PDCCH maximum repetition times are different.

In an embodiment of the present invention, the first reduction factor may be a predefined factor, or may be obtained by multiplying two factors. For example, the first reduction factor is the first factor, or the first reduction factor is the product of the second factor and the third factor; preferably, the first factor is equal to the product of the second factor and the third factor.

In the case where the first reduction factor is the first factor, for example, the set of PDCCH maximum number of repetitions Rmax is {1,2,4,8,16, 32, 64, 128, 256, 512, 1024, 2048 }. The first factor is

It should be noted that the above-mentioned values 1.25,1.5,2, etc. take into account that the early indication signal needs to avoid the synchronization signal/broadcast channel/system message 1 and other system messages, i.e. the first reduction factor is associated with the occupied ratio of the target subframe. For example, the target subframe is occupied by a synchronization signal, broadcast channel or system information block SIB1, resulting in a subframe occupancy of 80% for the actual transmission of the early indication signal (i.e. the overhead of the subframe where the synchronization signal, broadcast channel or system information block SIB1 is located is 20%) Thus, the first reduction factor of 1/(80%) is 1.25.

Likewise, the value of the first factor may be different for different Rmax in order to better adapt to different Rmax. E.g. Rmax 2048, then the first factor

spare refers to a spare value; when Rmax is 1, the first factor is {1,2,3,4, spare }.

In the case where the first reduction factor is a product of a second factor and a third factor, for example, the set of PDCCH maximum number of repetitions Rmax is {1,2,4,8,16, 32, 64, 128, 256, 512, 1024, 2048}, and the second factor indicates 4 meanings by 2 bits, and is defined as

The third factor represents 2 meanings by 1bit, and is {1.25,2 }. If Rmax is 2048, the second factor is

The third factor is 1.25, then the first reduction factor is

Similarly, to better adapt to different Rmax, the values of the second factor and the third factor may be different for different Rmax. For example, Rmax is 2048 and the second factor is

The third factor is {1.25,2 }; for another example, Rmax is 1, the second factor is {1,2, spare }, and the third factor is {1.5,2 }.

Preferably, in the above embodiment of the present invention, determining the first time duration according to the maximum number of repetitions of the PDCCH and a first reduction factor includes:

determining the first time length according to a third formula; wherein the third formula is: l2 ═ Rmax × C1; or the third formula is:

alternatively, the third formula is:

wherein L2 is the first length of time; rmax is the maximum repetition number of the PDCCH; c1 is the first reduction factor.

Alternatively, in the case where the duplex mode of the current communication system is the time division duplex mode,

determining the first time length according to the maximum repetition number of the PDCCH and a first reduction factor, comprising:

determining the first time length according to a fourth formula; wherein the fourth formula is: l2 ═ Rmax × C1 ÷ Q1; or the fourth formula is:

alternatively, the fourth formula is:

wherein L2 is the first length of time; rmax is the maximum repetition number of a PDCCH of a cell where the terminal is located; c1 is a first reduction factor; q1 is a first coefficient associated with the fraction of downlink subframes in time division duplex mode.

Preferably, Q1 is the proportion of downlink subframes.

Preferably, the first coefficient may be indicated by uplink and downlink subframe configuration information, and may also be sent through SIB signaling; correspondingly, the method further comprises the following steps:

receiving a system message from a network side device, wherein the system message carries an indication field of the first coefficient; alternatively, the first and second electrodes may be,

receiving uplink and downlink subframe configuration information (TDD UL DL configuration), and determining the first coefficient according to the uplink and downlink subframe configuration information. Different uplink and downlink subframe configuration information corresponds to different first coefficients.

For example, for a TDD system, the association between the uplink and downlink subframe configuration information and the first coefficient is shown in table 1. For frequency division duplex, FDD, systems, there is no first coefficient, or the first coefficient is 1 (100%).

Uplink and downlink subframe configuration information	First coefficient
		0	20 percent or 40 percent
1	40% or 60%
		2	60 percent or 80 percent
3	60 percent or 70 percent
		4	70 percent or 80 percent
5	80 percent or 90 percent
		6	30 percent or 50 percent

TABLE 1

Further, the value of the first reduction factor is associated with a duplex mode of the current communication system; the values of the first reduction factors corresponding to different duplex modes are different;

wherein, the duplex mode of the current communication system comprises: frequency division duplex FDD mode or time division duplex TDD mode.

The value of the first reduction factor may be different for TDD and FDD systems.

In the case where the first reduction factor is the first factor, for example, in the case of an FDD system, Rmax is 2048, the first factor is

For TDD systems, Rmax is 2048, then the first factor is

Namely, the value of the first reduction factor takes the occupation ratio factor of the downlink subframe into consideration.

In the case where the first reduction factor is the product of the second and third factors, e.g. Rmax 2048 for FDD systems, the second factor is

The third factor is {1.25,2 }; for TDD systems, Rmax is 2048, then the second factor is

The third factor is {1.25,2 }; or, the second factor is

The third factor is {1.25/Q1,2/Q1 }.

For example, as shown in fig. 3, T1 is the start time of the first time length. T2 is the end time of the first time length. T3 is the start time of PO corresponding to the advance instruction signal.

Then, the start time T1 of the first time length is PO start time-time gap-the first time length is T3-L1-L2.

determining the first time length according to the maximum duration of the advance indication signal and a second time length.

The second time length is sent or predefined through SIB signaling, and correspondingly, the embodiment of the present invention further includes:

acquiring the predefined second time length; alternatively, the first and second electrodes may be,

and receiving a system message from the network side equipment, wherein the system message carries the indication domain of the second time length.

Preferably, the determining the first time length according to the maximum duration of the advance indication signal and the second time length includes:

determining the first time length according to a fifth formula; wherein the fifth formula is: l2 ═ Lmax + L3; alternatively, the fifth formula is: l2 ═ (Lmax + L3)/Q2;

wherein L2 is the first length of time and L3 is the second length of time; lmax is the maximum duration of the advance indication signal; q2 is a second coefficient associated with the fraction of downlink subframes in time division duplex mode.

For example, for an FDD system, the maximum durations Lmax {1,4,8,16,32} of the advance indicator signals correspond to second durations {1,2,4,8,16}, respectively, and the first duration L2 is {1,4,8,16,32} + {1,2,4,8,16} + {2,6,12,24,48 }. For the TDD system, the following subframe ratio is 50%, and the first time length is { {1,4,8,16,32} + {1,2,4,8,16}/Q2} - {2,6,12,24,48 }/50% }.

Further, the second coefficient may be indicated by uplink and downlink subframe configuration information, and may also be sent through SIB signaling, and the method further includes:

receiving a system message from a network side device, wherein the system message carries an indication field of the second coefficient; alternatively, the first and second electrodes may be,

and receiving uplink and downlink subframe configuration information (TDD UL DL configuration), and determining the second coefficient according to the uplink and downlink subframe configuration information. And different uplink and downlink subframe configuration information corresponds to different second coefficients.

For example, for a TDD system, the association between the uplink and downlink subframe configuration information and the second coefficient is shown in table 2. For frequency division duplex, FDD, systems, there is no second coefficient, or the second coefficient is 1 (100%).

Uplink and downlink subframe configuration information	Second coefficient of
		0	20 percent or 40 percent
1	40% or 60%

Further, a value of the second time length is associated with a maximum duration of the advanced indication signal; and the values of the second time lengths corresponding to the maximum duration of different advanced indication signals are different.

Or the value of the second time length is associated with the maximum repetition number Rmax of the PDCCH, and the second time lengths corresponding to different Rmax are different.

Further, the second time length is determined by advancing the maximum duration of the indication signal and a second reduction factor. Correspondingly, the method further comprises the following steps:

alternatively, the sixth formula is:

wherein L3 is the second length of time; lmax is the maximum duration of the advance indication signal; c2 is a second discounting factor, C2 is associated with the proportion of the target-subframe that is occupied. For example, L3 equals 16 × 0.5 equals 8, Lmax equals 16, and C2 equals 0.5.

And the value of the third folding factor is associated with the maximum repetition number of the PDCCH; and the values of the third folding factors corresponding to different PDCCH maximum repetition times are different.

For example, Rmax takes a set of values {1,2,4,8,16, 32, 64, 128, 256, 512, 1024, 2048}, and the third fold factor takes a set of values:

if the maximum duration of the early indication signal is assumed to be {1,4,16,32 }; when Rmax is 2048 and the third folding factor is 1/128, the maximum duration of the advanced indication signal is

For example, as shown in fig. 4, T1 is the start time of the first length of time, T1 is also the start time of the maximum duration of the advance indicator signal, and T2 is the end time of the maximum duration of the advance indicator signal. T3 is the end time of the first length of time. T4 is the start time of the first PO corresponding to the advance instruction signal.

The first time length L2 is the maximum duration Lmax of the advance indication signal + the second time length L3; accordingly, the first time length starting time T1 is PO starting time-time gap-the first time length is T4-L1- (Lmax + L3).

For another example, as shown in fig. 5, T1 is the starting time of the second time length, and T1 is also the starting time of the first time length; t2 is the start time of the maximum duration of the advance indicator signal, T3 is the end time of the maximum duration of the advance indicator signal, and T3 is also the end time of the first length of time. T4 is the start time of the first PO corresponding to the advance instruction signal.

The first time length L2 is equal to the second time length L3+ the maximum duration Lmax of the advance indication signal; accordingly, the first time length starting time T1 is PO starting time-time gap-the first time length is T4-L1- (L3+ Lmax).
