Description

Communication method, device and system

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method, device, and system.

Background

In a wireless communication system, a terminal device has two states, wherein one state is a connection state which indicates that the terminal device has established connection with a network device and can directly communicate; one is an idle state or a sleep state, which means that the terminal device cannot directly communicate with the network device. When no service data is transmitted or received, the terminal device can enter an idle state to reduce power consumption. When the network device needs to send service data to the terminal device or needs to report some service data to the terminal device, the network device may notify the terminal device through a paging mechanism, and the idle terminal device may periodically wake up to monitor a Physical Downlink Control Channel (PDCCH), detect whether a paging scheduling message exists in the PDCCH, and if the paging scheduling message exists and the paging scheduling message is for its own paging scheduling, the idle terminal device switches to a connection state so as to send or receive the service data. The location where the terminal wakes up is called Paging Occasion (PO).

However, in the current internet of things, there are many services that are actively reported, that is, the above behaviors are dominant, and the paging probability is low, so that the network device does not send a corresponding paging scheduling message in a PDCCH search space that mostly uses a subframe corresponding to a PO as an initial subframe, but the terminal device still needs to monitor the PDCCH from each PO corresponding to the terminal device. In the PDCCH search space using the subframe corresponding to each PO as the starting subframe, the terminal device determines that there is no paging scheduling message until all candidate positions are detected in the PDCCH search space in a blind manner from the first candidate position, which is a waste of power consumption for the terminal device.

Based on this, in the prior art, the network device may transmit a wakeup signal (WUS) to the terminal device before PO, where the WUS is used to indicate that the terminal device needs to monitor PDCCH. When the terminal equipment detects the WUS before PO, the PDCCH needs to be monitored continuously; if the terminal device does not detect the WUS before the PO, the terminal device may not monitor the PDCCH, so that the power consumption of the terminal device can be saved.

However, in the transmission time of the WUS, the base station cannot transmit downlink data or a downlink channel on a corresponding Physical Resource Block (PRB), so that the whole downlink channel is blocked, and the scheduling of the base station is affected.

Disclosure of Invention

The embodiment of the application provides a communication method, equipment and a system, which are used for solving the problem that downlink signals are blocked in the sending time of the current wake-up signals, so that the scheduling of a base station is influenced.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical solutions:

in a first aspect, a communication method is provided, and the method includes: determining a first resource, wherein the first resource is a downlink transmission interval resource; if the first resource and the second resource are overlapped on a time domain, receiving a wake-up signal on a third resource, wherein the second resource is a resource which is determined according to the maximum duration of the wake-up signal and is used for transmitting the wake-up signal; the third resource includes a part or all of the second resource except for a part overlapping the first resource in a time domain. In other words, the third resource includes a partial resource of the second resource, and the third resource is not overlapped with the first resource in a time domain. Based on the communication method, in the embodiment of the present application, if the second resource used for transmitting the wake-up signal overlaps the downlink transmission interval resource in the time domain, the wake-up signal is received on part or all of the second resource except the part overlapping the first resource in the time domain, and the wake-up signal is not received on the part overlapping the first resource and the second resource in the time domain, so that the part overlapping the first resource and the second resource in the time domain can perform downlink data or downlink channel transmission, thereby reducing downlink channel congestion and reducing the influence on base station scheduling.

In one possible design, if the first resource overlaps the second resource in the time domain, receiving a wake-up signal on a third resource includes: in the case that (P × the maximum duration of the wake-up signal) is not less than (Q × the first threshold), if the first resource and the second resource overlap in the time domain, the wake-up signal is received on the third resource, and P and Q are both positive integers. Illustratively, the values of P and Q may both be 1. That is, in the embodiment of the present application, in the case that (P × maximum duration of the wake-up signal) is not less than (Q × first threshold), it is further determined whether the first resource and the second resource overlap in the time domain; otherwise, in case (P × maximum duration of the wake-up signal) is smaller than (Q × first threshold), it is considered that there is no first resource in the wake-up signal transmission.

In a second aspect, a communication method is provided, the method comprising: determining a first resource, wherein the first resource is a downlink transmission interval resource; if the first resource and the second resource are overlapped on a time domain, sending a wake-up signal on a third resource, wherein the second resource is a resource which is determined according to the maximum duration of the wake-up signal and is used for transmitting the wake-up signal; the third resource includes a part or all of the second resource except for a portion overlapping with the first resource in a time domain. Based on the communication method, in the embodiment of the present application, if the second resource for transmitting the wake-up signal overlaps with the downlink transmission interval resource in the time domain, the wake-up signal is received on part or all of the second resource except for the part overlapping with the first resource in the time domain, and the wake-up signal is not received on the part overlapping with the second resource in the time domain, so that the part overlapping with the first resource in the time domain can perform downlink data or downlink channel transmission, thereby reducing downlink channel congestion and reducing the influence on base station scheduling.

In one possible design, if the first resource overlaps the second resource in the time domain, sending the wake-up signal on a third resource includes: in the case that (P × the maximum duration of the wake-up signal) is not less than (Q × the first threshold), if the first resource and the second resource overlap in the time domain, the wake-up signal is transmitted on the third resource, where P and Q are both positive integers. Illustratively, the values of P and Q may both be 1. That is, in the embodiment of the present application, in the case that (P × maximum duration of the wake-up signal) is not less than (Q × first threshold), it is further determined whether the first resource and the second resource overlap in the time domain; otherwise, in case (P × maximum duration of the wake-up signal) is smaller than (Q × first threshold), it is considered that there is no first resource in the wake-up signal transmission.

With reference to the first aspect or the second aspect, in a possible design, a first subframe of a time-domain overlapping portion of the first resource and the second resource is an x 1-th target subframe of the second resource, a last subframe of the time-domain overlapping portion of the first resource and the second resource is a y 1-th target subframe of the second resource, x1 is a positive integer less than or equal to N, y1 is a positive integer less than N, the target subframe is a subframe of a sequence that can be used for mapping the wake-up signal, and N is the number of target subframes of the sequence that are actually used for mapping the wake-up signal; wherein the third resource comprises: (x 1-1) target-subframes before the x 1-th target-subframe, and (N-y 1) target-subframes after the y 1-th target-subframe. That is, the wake-up signals on the x1 st to y1 st target-subframes on the second resource are discarded (drop). It should be noted that, in the embodiment of the present application, dropping (drop) may be understood that the x1 st target subframe to the y1 st target subframe on the second resource are also used for mapping the sequence of the wake-up signal, but are not used for transmitting the wake-up signal.

With reference to the first aspect or the second aspect, in a possible design, a first subframe of a time-domain overlapping portion of the first resource and the second resource is an x 2-th target subframe of the second resource, a last subframe of the time-domain overlapping portion of the first resource and the second resource is a y 2-th target subframe of the second resource, x2 is a positive integer less than or equal to N, y2 is a positive integer greater than or equal to N, the target subframe is a subframe of a sequence that can be used to map the wake-up signal, and N is the number of target subframes of the sequence that are actually used to map the wake-up signal; wherein the third resource comprises: (x 2-1) target-subframes before the x 2-th target-subframe. That is, the wake-up signals on the x2 nd to nth target subframes on the second resource are discarded (drop). It should be noted that in the embodiment of the present application, the dropped (drop) may be understood that the x2 nd to nth target subframes on the second resource are also used for mapping the sequence of the wake-up signal, but are not used for transmitting the wake-up signal.

With reference to the first aspect or the second aspect, in a possible design, the target subframes of the sequence of N mapping wake-up signals include a first subframe of the second resource to an nth subframe of the second resource.

With reference to the first aspect or the second aspect, in a possible design, a first subframe of a time-domain overlapping portion of the first resource and the second resource is an x 3-th target subframe of the second resource, a last subframe of the time-domain overlapping portion of the first resource and the second resource is a y 3-th target subframe of the second resource, x3 is a positive integer less than or equal to N, y3 is a positive integer less than or equal to M, and the target subframe is a subframe of a sequence that can be used to map the wake-up signal; n is the number of target sub-frames actually used for mapping the sequence of the wake-up signal, and M is the number of target sub-frames in the maximum duration of the wake-up signal; wherein the third resource comprises: s1 target subframes before the x3 th target subframe and S2 target subframes after the y3 th target subframe, wherein S1 is an integer, S2 is an integer, and S1+ S2 is not more than N. It can be understood that the sequence of the wake-up signals on the x 3rd to nth target subframes is mapped onto the (y 3+ 1) th to (y 3+ S2) th target subframes, which means that the wake-up signals on the x 3rd to nth target subframes are transmitted with a delay (postpone). It should be noted that, in the embodiment of the present application, the delayed sending of the wake-up signal (posttone) may be understood as that the wake-up signal on the time domain overlapping resource of the first resource and the second resource and the wake-up signal on the resource after the overlapping resource are both delayed to be sent, that is, if the wake-up signal is originally sent on the target subframe Z without the first resource, when there is the first resource and the first resource is the target subframe Z, the wake-up signal is sent on the target subframe Z +1, and then the wake-up signal is continuously sent on the subsequent target subframe.

With reference to the first aspect or the second aspect, in a possible design, a time domain starting position of the third resource is advanced by K target subframes relative to a time domain starting position of the first resource or the second resource, where K is a number of subframes of a time domain overlapping portion of the first resource and the second resource, and K is a positive integer. Based on the scheme, it can be ensured that the end position of the S2 target subframes after the y 3rd target subframe does not exceed the end position of the second resource after the wake-up signal is transmitted with delay (postdone), so that the problem that the end position of the S2 target subframes after the y 3rd target subframe may exceed the end position of the second resource to the next wake-up signal resource, or may overlap with the gap between the wake-up signal resource and the PO, or may overlap with the PO after the wake-up signal is transmitted with delay (postdone) can be avoided.

In a third aspect, a communication method is provided, where the method includes: determining a first resource, wherein the first resource is a downlink transmission interval resource; if the first resource and the fourth resource are overlapped on the time domain, receiving a wake-up signal on the third resource; the fourth resource is a wake-up signal resource with the duration less than or equal to the maximum duration of the wake-up signal, and the third resource and the first resource are not overlapped in the time domain. Based on the communication method, in the embodiment of the present application, if the first resource and the fourth resource overlap in the time domain, the wake-up signal is received on the third resource that does not overlap in the time domain with the first resource, and the wake-up signal is not received on the overlapping portion of the first resource and the fourth resource, so that the overlapping portion of the first resource and the second resource in the time domain can perform transmission of downlink data or a downlink channel, thereby reducing congestion of the downlink channel and reducing the influence on scheduling of the base station.

In one possible design, if the first resource overlaps with the fourth resource in the time domain, receiving the wake-up signal on the third resource includes: in the case that (P × the maximum duration of the wake-up signal) is not less than (Q × the first threshold), if the first resource and the fourth resource overlap in the time domain, the wake-up signal is received on the third resource, and P and Q are both positive integers. Illustratively, the values of P and Q may both be 1. That is, in the embodiment of the present application, in the case that (P × maximum duration of the wake-up signal) is not less than (Q × first threshold), it is further determined whether the first resource and the fourth resource overlap in the time domain; otherwise, in case (P × maximum duration of the wake-up signal) is smaller than (Q × first threshold), it is considered that there is no first resource in the wake-up signal transmission. That is to say, in the embodiment of the present application, in the case that (P × maximum duration of the wake-up signal) is not less than (Q × first threshold), it is further determined whether the first resource and the fourth resource overlap in the time domain; otherwise, in case (P × maximum duration of the wake-up signal) is smaller than (Q × first threshold), it is considered that there is no first resource in the wake-up signal transmission.

In a fourth aspect, a communication method is provided, the method comprising: determining a first resource, wherein the first resource is a downlink transmission interval resource; if the first resource and the fourth resource are overlapped on the time domain, sending a wake-up signal on the third resource; the fourth resource is a wake-up signal resource with a duration less than or equal to the maximum duration of the wake-up signal, and the third resource is not overlapped with the first resource in a time domain. Based on the communication method, in the embodiment of the present application, if the first resource and the fourth resource are overlapped in the time domain, the wake-up signal is sent on the third resource that is not overlapped in the time domain with the first resource, and the wake-up signal is not sent on the overlapped portion of the first resource and the fourth resource, so that the overlapped portion of the first resource and the second resource in the time domain can perform transmission of downlink data or a downlink channel, thereby reducing downlink channel congestion and reducing the influence on base station scheduling.

In one possible design, if the first resource overlaps with the fourth resource in the time domain, sending a wake-up signal on the third resource includes: in the case that (P × the maximum duration of the wake-up signal) is not less than (Q × the first threshold), if the first resource and the fourth resource overlap in the time domain, the wake-up signal is transmitted on the third resource, and P and Q are both positive integers. Illustratively, the values of P and Q may both be 1. That is, in the embodiment of the present application, in the case that (P × maximum duration of the wake-up signal) is not less than (Q × first threshold), it is further determined whether the first resource and the fourth resource overlap in the time domain; otherwise, in case (P × maximum duration of the wake-up signal) is smaller than (Q × first threshold), it is considered that there is no first resource in the wake-up signal transmission.

With reference to the third aspect or the fourth aspect, in one possible design, the wake-up signal on the time-domain overlapping resource of the first resource and the fourth resource is discarded.

Exemplarily, a first subframe of a time-domain overlapping portion of the first resource and the fourth resource is an x 1-th target subframe of the fourth resource, a last subframe of the time-domain overlapping portion of the first resource and the fourth resource is a y 1-th target subframe of the fourth resource, x1 is a positive integer less than or equal to N, y1 is a positive integer less than N, the target subframe is a subframe of a sequence that can be used for mapping the wake-up signal, and N is the number of target subframes of the sequence that are actually used for mapping the wake-up signal; wherein the third resource comprises: (x 1-1) target-subframes before the x1 st target-subframe and (N-y 1) target-subframes after the y1 st target-subframe on the fourth resource. That is, the wake-up signals on the x1 st to y1 st target subframes on the fourth resource are discarded (drop). It should be noted that in the embodiment of the present application, the dropped (drop) may be understood that the x1 st target subframe to the y1 st target subframe on the fourth resource are also used for mapping the sequence of the wake-up signal, but are not used for transmitting the wake-up signal.

Exemplarily, a first subframe of a portion where the first resource and the fourth resource overlap in a time domain is an x2 th target subframe of the second resource, a last subframe of the portion where the first resource and the second resource overlap in the time domain is an nth target subframe of the fourth resource, x2 is a positive integer less than or equal to N, the target subframe is a subframe that can be used for mapping a sequence of the wake-up signal, and N is the number of target subframes actually used for mapping the sequence of the wake-up signal; wherein the third resource comprises: (x 2-1) target-subframes before the x 2-th target-subframe on the fourth resource. That is, the wake-up signals on the x2 nd to nth target subframes on the fourth resource are discarded (drop). It should be noted that in the embodiment of the present application, the dropped (drop) may be understood that the x2 nd to nth target subframes on the fourth resource are also used for mapping the sequence of the wake-up signal, but are not used for transmitting the wake-up signal.

Optionally, the N target subframes for mapping the sequence of the wake-up signal include a first subframe of a fourth resource to an nth subframe of the fourth resource.

With reference to the third aspect or the fourth aspect, in one possible design, the wake-up signal on the time-domain overlapping resource of the first resource and the second resource is sent with a delay.

Exemplarily, a first subframe of a portion where the first resource and the fourth resource overlap in a time domain is an x 3-th target subframe of the second resource, a last subframe of the portion where the first resource and the second resource overlap in the time domain is a y 3-th target subframe of the second resource, x3 is a positive integer less than or equal to N, y3 is a positive integer less than or equal to N, the target subframe is a subframe of a sequence that can be used for mapping the wake-up signal, and N is the number of target subframes actually used for mapping the sequence of the wake-up signal; wherein the third resource comprises: s1 target subframes before the x3 th target subframe and S2 target subframes after the y3 th target subframe, wherein S1 is an integer, S2 is an integer, and S1+ S2 is not more than N. It can be understood that the sequence of the wake-up signals on the x 3rd to nth target subframes is mapped onto the (y 3+ 1) th to (y 3+ S2) th target subframes, which means that the wake-up signals on the x 3rd to nth target subframes are transmitted with a delay (postpone). It should be noted that, in this embodiment of the application, the delayed sending (postdone) of the wake-up signal may be understood as that the wake-up signal on the time domain overlapping resource of the first resource and the second resource and the wake-up signal on the resource after overlapping the resource are both delayed to be sent, that is, if the wake-up signal is originally sent on the target subframe Z without the first resource, when there is the first resource and the first resource is the target subframe Z, the wake-up signal is sent on the target subframe Z +1, and then the wake-up signal is continuously sent on the subsequent target subframe.

With reference to the third aspect or the fourth aspect, in a possible design, a wake-up signal after a subframe k is discarded, where the subframe k is an end subframe of a second resource, and the second resource is a resource used for transmitting the wake-up signal and determined according to a maximum duration of the wake-up signal. Based on this scheme, it is possible to avoid a problem that the end position of S2 target subframes after the y 3rd target subframe may exceed the end position of the second resource to the next wake-up signal resource after the wake-up signal is delayed to be transmitted (postdone), or may overlap with a gap between the wake-up signal resource and a PO, or may overlap with a PO.

With reference to the third aspect or the fourth aspect, in a possible design, a time domain starting position of the third resource is advanced by K target subframes relative to a time domain starting position of the fourth resource or the first resource, where K is a number of target subframes of a time domain overlapping portion of the first resource and the second resource, and K is a positive integer, and the second resource is a resource used for transmitting the wake-up signal and determined according to a maximum duration of the wake-up signal. Based on the scheme, it can be ensured that the end position of the S2 target subframes after the y 3rd target subframe does not exceed the end position of the second resource after the wake-up signal is transmitted in a delayed manner (postdone), so that the problem that the end position of the S2 target subframes after the y 3rd target subframe may exceed the end position of the second resource to the next wake-up signal resource, or may overlap with the gap between the wake-up signal resource and the PO, or may overlap with the PO after the wake-up signal is transmitted in a delayed manner (postdone), wherein the second resource is a resource for transmitting the wake-up signal determined according to the maximum duration of the wake-up signal.

Detailed Description

To facilitate understanding of the technical solutions of the embodiments of the present application, a brief description of relevant technologies and terms of the present application is first given as follows.

First, the internet of things (IoT):

the IoT is the "internet of things connected". It extends the user end of the internet to any article to article, so that information exchange and communication can be carried out between any article and article. Such a communication method is also called Machine Type Communications (MTC). The communicating nodes are called MTC terminals or MTC devices. Typical IoT applications include smart grid, smart agriculture, smart transportation, smart home, and environmental detection, among others.

Since the internet of things needs to be applied to various scenes, such as from outdoor to indoor and from above ground to underground, many special requirements are put on the design of the internet of things. For example, the MTC terminal in some scenarios is applied in an environment with poor coverage, such as an electricity meter, a water meter, etc., which is usually installed indoors or even in a basement where wireless network signals are poor, and therefore a coverage enhancement technology is needed to solve the problem. Alternatively, the number of MTC terminals in some scenarios is much larger than the number of devices for person-to-person communication, that is, large-scale deployment is required, so that MTC terminals are required to be available and used at very low cost. Or, because data packets transmitted by the MTC terminal in some scenarios are small and not sensitive to delay, it is required to support the low-rate MTC terminal. Or, since the MTC terminal is powered by a battery in most cases, but in many scenarios, the MTC terminal is required to be able to use for more than ten years without replacing the battery, which requires the MTC terminal to be able to operate with extremely low power consumption.

To meet the above requirements, the mobile communication standardization organization third generation partnership project (3 rd generation partnership project,3 gpp) has studied a method of supporting an internet of things with extremely low complexity and low cost in a cellular network through a new research topic at 62 times of a Radio Access Network (RAN) # overall meeting, and has established a narrow band internet of things (narrow band internet browsing,

NB-IoT) topic. Wherein, the bandwidth of NB-IoT is 180kHz, i.e., one PRB.

Second, WUS:

as shown in figure 1a shows that in 3GPP Release (Rel) 15, the maximum duration of WUS (maximum WUS duration) is L _NWUSmax . There is an interval (gap) between the WUS and the corresponding PO, and the role of this gap is mainly to leave the terminal device a period of time to wake up to blind detect the PDCCH at the PO. The gap may be a gap of Discontinuous Reception (DRX), a short gap of extended DRX (eDRX), and a long gap of eDRX, which is not limited herein.

The method comprises the steps that a terminal device detects whether WUS exists on WUS resources, and if the terminal device detects the WUS and indicates that a base station possibly pages the terminal device, the terminal device starts to monitor a PDCCH at a PO; if the terminal device does not detect the WUS, the base station does not page the terminal device, and the terminal device enters a sleep state, so that the power consumption of the terminal device can be saved. The WUS transmission starts from the start of the WUS resource. The actual duration of WUS (WUS actual duration) may be an exponential multiple of 2 subframes, such as 1,2,4,8, 1 _NWUSmax As shown in table one.

Watch 1

L _NWUSmax	Actual WUS duration set
		1	{1}
2	{1，2}
		4	{1，2，4}
8	{1，2，4，8}
		16	{1，2，4，8，16}
32	{1，2，4，8，16，32}
		64	{1，2，4，8，16，32，64}
128	{1，2，4，8，16，32，64，128}
		256	{1，2，4，8，16，32，64，128，256}
512	{1，2，4，8，16，32，64，128，256，512}

However, since all terminal devices at the PO in fig. 1a need to detect WUS, then the blind detection of PDCCH at the PO is continued according to whether WUS is detected or not. Therefore, if the base station wants to page terminal device a and issues a WUS, but terminal device B also detects the WUS and wakes up, which may cause terminal device B to be mistakenly woken up (false wake up), thereby affecting the power consumption of terminal device B. Based on this, the 3gpp rel16 introduces packet processing for the terminal device at PO, with different packets corresponding to different WUSs. For example, the terminal devices at the PO may be divided into two groups, including group a and group B. group A corresponds to WUS1 (also called group WUS 1), WUS1 is used for instructing terminal equipment in group A on PO to monitor PDCCH and further receive paging messages; group B corresponds to WUS2 (also called group WUS 2), WUS2 is used for indicating terminal equipment in group B on PO to monitor PDCCH and further receive paging messages, thus the probability that the terminal equipment is awoken by mistake can be reduced, and the power consumption of the terminal equipment is saved.

Meanwhile, a common WUS for waking up all the grouped terminal devices at the PO is also introduced in 3GPP Rel-16. WUS 3 is, for example, a common WUS for waking up all groups of terminal devices at the PO.

It should be noted that the WUS resource in this embodiment of the present application may be a legacy WUS resource (WUS resource) (it may be understood that the WUS resource of Rel-15, i.e., the WUS resource in fig. 1 a) or the above group WUS resource (it may be understood that the group WUS resource may be the WUS resource of Rel-15, i.e., the first WUS resource in fig. 1b, or the WUS resource of Rel-16, i.e., the second WUS resource in fig. 1 b), which is not specifically limited in this embodiment of the present application.

For example, if the maximum duration of WUS =1024 and the actual duration of WUS is 512, it can be understood that the number of target subframes of the sequence for mapping WUS at maximum is 1024 and the number of target subframes of the sequence for mapping WUS at actual is 512. The target subframe herein is a subframe that can be used for mapping a sequence of WUSs, and includes a valid subframe and a subframe 4 transmitting a System Information Block (SIB) 1, where the subframe 4 transmitting the SIB1 is not a valid subframe. Is provided withA valid subframe refers to a subframe satisfying a certain condition, which may include, for example, condition 1 and condition 2, where condition 1 is that the subframe is not used for transmitting a Narrowband Primary Synchronization Signal (NPSS), a Narrowband Secondary Synchronization Signal (NSSS), a Narrowband Physical Broadcast Channel (NPBCH), and an SIB1-NB; condition 2 is that the subframe is configured as a valid subframe, and the related definition can refer to the prior art and is not described herein again.

The second resource in this embodiment is a resource for transmitting the wake-up signal determined according to the maximum duration of the wake-up signal, for example, the duration is L in fig. 1a _NWUSmax WUS resources of (1). It can be understood that the subframes on the second resource in this embodiment are all the target subframes defined above, in other words, the "xxx subframe" on the second resource and the "xxx target subframe" on the second resource are the same concept and may be replaced with each other, which is described herein in a unified manner and is not described in detail below.

The third resource in this embodiment includes part or all of the second resource except for a part overlapping with the first resource in the time domain, in other words, the third resource includes a part of the second resource, and the third resource does not overlap with the first resource in the time domain.

The communication method provided by the embodiment of the present application will be described in detail below with reference to fig. 1a to 5.

As shown in fig. 6, a communication method provided in this embodiment of the present application is described by taking the communication system shown in fig. 2 as an example, that is, assuming that a first communication device is a terminal device and a second communication device is a network device, the communication method provided in this embodiment of the present application includes the following steps:

s601, the network equipment determines a first resource.

Optionally, in this embodiment of the present application, the network device may determine configuration of a downlink transmission interval resource (that is, a first resource), where the configuration of the downlink transmission interval resource includes a period (which may be denoted as N) _gap，period ) Duration scale factor (which may be denoted as N) _gap，coeff ) And a first threshold value. Wherein, the initial time domain position of the downlink transmission interval resource satisfies the formula

n _f Indicating radio frame number, n _s Which indicates the number of the time slot,

meaning rounding down and mod meaning remainder. Duration (N) _{gap，duration} ) Satisfies N _{gap，duration} ＝N _gap，coeff N _gap，period The unit is a subframe.

Optionally, the first threshold in this embodiment of the present application may be a threshold N in an existing protocol _{gap，threshold} Or another threshold configured by the base station (which may be denoted as N) _{gap，threshold，WUS} ) E.g. base station configuring N by system messages _{gap，threshold，WUS} This is not particularly limited in the embodiments of the present application. Exemplary, N _{gap，threshold，WUS} Can be, for example, 16, 32, 64, 128, etc.

S602, the terminal device determines a first resource.

Optionally, in this embodiment of the application, the network device may send the configuration of the downlink transmission interval resource to the terminal device, and then the terminal device may determine the downlink transmission interval resource according to the configuration of the downlink transmission interval resource. For the description of the configuration of the downlink transmission interval resource, reference may be made to the step S601, which is not described herein again.

And S603, if the first resource and the second resource are overlapped on the time domain, the network equipment sends the WUS to the terminal equipment on the third resource. Accordingly, the terminal device receives the WUS from the network device on the third resource.

Optionally, in this embodiment of the application, if the first resource overlaps with the second resource in the time domain, the network device sends the WUS to the terminal device on a third resource, including: in the case where (P × maximum duration of WUS) is not less than (Q × first threshold), if the first resource overlaps the second resource in the time domain, the network device transmits WUS to the terminal device on the third resource, where P and Q are both positive integers. That is, in the embodiment of the present application, in the case where (P × maximum duration of WUS) is not less than (Q × first threshold), the network device further determines whether the first resource and the second resource overlap in the time domain; otherwise, in the case that (maximum duration of P × WUS) is less than (Q × first threshold), the network device considers that there is no first resource in the WUS transmission.

Optionally, in this embodiment of the application, if the first resource overlaps with the second resource in the time domain, the receiving, by the terminal device, the WUS from the network device on the third resource includes: in the case where (P × maximum duration of WUS) is not less than (Q × first threshold), if the first resource overlaps the second resource in the time domain, the terminal device receives WUS from the network device on the third resource, P and Q being positive integers. That is, in the embodiment of the present application, in the case where (the maximum duration of P × WUS) is not less than (Q × first threshold), the terminal device further determines whether the first resource overlaps with the second resource in the time domain, and otherwise, in the case where (the maximum duration of P × WUS) is less than (Q × first threshold), the terminal device regards that there is no first resource in WUS transmission.

For example, the values of P and Q may both be 1; or the value of P is 1, and the value of Q is a positive integer greater than 1; or Q is 1, P is a positive integer greater than 1.

Of course, in step S603, the terminal device or the network device may also compare the length (R) of the Common Search Space (CSS) of the first type (type-1) _max ) Whether downlink transmission interval resources exist for the WUS is determined according to the first threshold, which is not specifically limited in the embodiment of the present application.

It should be noted that "not less than" in the embodiments of the present application may be understood as "greater than or equal to", which is uniformly described herein and is not described below.

A specific description of the relative positions of the first resource, the second resource, and the third resource is given below.

Scene one: the N target subframes for mapping the sequence of WUSs include a first subframe of the second resource to an nth subframe of the second resource. It can also be understood that the sequence of WUSs is mapped to the first subframe of the second resource through the nth subframe of the second resource.

It should be noted that "several" in the embodiments of the present application may be understood as counting continuously from "the first", and are described in the entirety herein, and will not be described in detail below.

In a possible implementation manner, a first subframe of a time-domain overlapping portion of the first resource and the second resource is an x 1-th target subframe of the second resource, a last subframe of the time-domain overlapping portion of the first resource and the second resource is a y 1-th target subframe of the second resource, x1 is a positive integer less than or equal to N, and y1 is a positive integer less than N. The third resource includes: (x 1-1) target-subframes before the x 1-th target-subframe, and (N-y 1) target-subframes after the y 1-th target-subframe.

It should be noted that "xx before" or "xx after" in this embodiment does not include "xx" itself, and as described above, the (x 1-1) target-subframes before the x1 st target-subframe do not include the x1 st target-subframe, and the (N-y 1) target-subframe after the y1 st target-subframe does not include the y1 st target-subframe, which is described in a unified manner herein and is not described again.

For example, assuming that x1 is not 1, the location distribution maps of the first resource, the second resource, and the third resource may be as shown in fig. 7. The (x 1-1) target subframes before the x1 st target subframe may include a first target subframe on the second resource to a (x 1-1) th target subframe on the second resource, and the (N-y 1) target subframes after the y1 st target subframe include a (y 1+ 1) th target subframe on the second resource to an nth target subframe on the second resource. The x1 st to y1 st target-subframes on the second resource are used for mapping the sequence of WUSs, but are not used for transmitting the corresponding WUSs, that is, the WUSs on the x1 st to y1 st target-subframes on the second resource are discarded (drop). It should be noted that, in the embodiment of the present application, dropped (drop) may be understood that a target subframe on a time-domain overlapping resource of a first resource and a second resource may also be used for mapping a sequence of WUSs, but is not used for transmitting WUSs.

Alternatively, for example, assuming that x1 is equal to 1, the location distribution maps of the first resource, the second resource and the third resource may be as shown in fig. 8. Wherein, (x 1-1) target subframes before the x1 st target subframe are 0 target subframes, and (N-y 1) target subframes after the y1 st target subframe include (y 1+ 1) th target subframe on the second resource to nth target subframe on the second resource. The 1 st to y1 st target-subframes on the second resource are used for mapping the sequence of WUSs, but are not used for transmitting the corresponding WUSs, that is, the WUSs on the 1 st to y1 st target-subframes on the second resource are discarded (drop).

It should be noted that fig. 8 exemplarily illustrates that the starting time domain position of the first resource is earlier than the starting position of the second resource. Of course, the starting time domain position of the first resource may also be the same as the starting position of the second resource, and this is not specifically limited in this embodiment of the application.

In another possible implementation manner, a first subframe of a time-domain overlapping portion of the first resource and the second resource is an x 2-th target subframe of the second resource, a last subframe of the time-domain overlapping portion of the first resource and the second resource is a y 2-th target subframe of the second resource, x2 is a positive integer less than or equal to N, and y2 is a positive integer greater than or equal to N. The third resource includes: (x 2-1) target-subframes before the x 2-th target-subframe.

For example, the location profile of the first resource, the second resource, and the third resource may be as shown in fig. 9. The (x 2-1) target subframes on the second resource are used for mapping the sequence of the WUs but not for transmitting the corresponding WUs, namely the WUs from the (x 2) -th target subframe to the Nth target subframe on the second resource are discarded (drop).

Scene two: the first subframe of the overlapping part of the first resource and the second resource in the time domain is the x3 th target subframe of the second resource, the last subframe of the overlapping part of the first resource and the second resource in the time domain is the y 3rd target subframe of the second resource, x3 is a positive integer less than or equal to N, and y3 is a positive integer less than or equal to M. The target-subframe is a subframe of a sequence that can be used to map WUSs. N is the number of target subframes of the sequence actually used for mapping WUS, which can be understood as the actual duration of WUS; m is the number of target-subframes within the maximum duration of the WUS, and can be understood as the maximum duration of the WUS. Of course, the actual duration of the WUS may be less than or equal to the maximum duration of the WUS. For example, M =1024 indicates that the maximum duration of WUS is 1024, and it can be understood that 1024 target subframes are included in the maximum duration of WUS, that is, the number of target subframes that can be used to map WUS sequences in the maximum duration of WUS is 1024. In this case, N may take any one of 1,2,4,8, 16, 32, 64, 128, 256, 512, or 1024.

Wherein, in this scenario, the third resource includes: s1 target subframes before the x3 th target subframe and S2 target subframes after the y 3rd target subframe, wherein S1 is an integer, S2 is an integer, and S1+ S2 is not more than N. It is understood that the sequence of WUS on the x3 th to nth target subframes is mapped onto the (y 3+ 1) th to (y 3+ S2) th target subframes, which means that WUS on the x 3rd to nth target subframes is delayed from being transmitted (postdone). It should be noted that in this embodiment of the present application, the WUS is delayed to transmit (postbone), which is to be understood that the WUS on the time domain overlapping resource of the first resource and the second resource, and the WUS on the resource after overlapping the resource are both delayed to transmit, that is, assuming that the WUS originally transmits on the target subframe Z without the first resource, when there is the first resource and the first resource is the target subframe Z, the WUS transmits on the target subframe Z +1, and then continues to transmit the WUS on the subsequent target subframe.

For example, assuming that x3 is not 1, the location distribution maps of the first resource, the second resource and the third resource may be as shown in fig. 10 or fig. 11. Wherein S1 target subframes before the x 3rd target subframe include a first valid subframe of the second resource to an (x 3-1) th target subframe of the second resource, S2 target subframes after the y 3rd target subframe include an (y 3+ 1) th target subframe of the second resource to an (N + y3-x3+ 1) th target subframe of the second resource, S1+ S2= N, S1= x3-1, and S2= N-x3+1.

Alternatively, for example, assuming that x3 is not 1, the location distribution maps of the first resource, the second resource and the third resource may be as shown in fig. 12. Wherein S1 target subframes before the x 3rd target subframe include a first valid subframe of the second resource to an (x 3-1) th target subframe of the second resource, and S2 target subframes after the y 3rd target subframe include an (y 3+ 1) th target subframe of the second resource to a last target subframe of the second resource and a part of target subframes on the WUS resource after the second resource, wherein S1+ S2= N, and S1= x3-1. It can be seen that, after the WUS on the x 3rd to N th target subframes is delayed for transmission (postdone), the end position of S2 target subframes after the y 3rd target subframe may exceed the end position of the second resource to the next WUS resource, or may overlap with the gap between the WUS resource and the PO, or may overlap with the PO. Further, optionally, in this embodiment of the application, after the WUS on the x3 th target subframe to the nth target subframe is delayed to be transmitted (postdone), in S2 target subframes after the y 3rd target subframe, target subframes beyond the end position of the second resource may be discarded (drop). For example, as shown in fig. 13, the S2 target-subframes after the y 3-th target-subframe include the (y 3+ 1) -th target-subframe of the second resource to the last target-subframe of the second resource, where S1+ S2 < N. This may avoid the problem that after the WUS on the x 3rd to nth target subframes is delayed to transmit (postdone), the end position of S2 target subframes after the y 3rd target subframe may exceed the end position of the second resource to the next WUS resource, or may overlap with the gap between the WUS resource and the PO, or may overlap with the PO.

Alternatively, for example, assuming that x3 is equal to 1, the location distribution maps of the first resource, the second resource and the third resource may be as shown in fig. 14 or fig. 15. Wherein S1 target subframes before the x3 th target subframe include 0 target subframes, S2 target subframes after the y3 th target subframe include (y 3+ 1) th target subframe of the second resource to (N + y 3) th target subframe of the second resource, S1+ S2= N, S1=0, S2= N.

It should be noted that fig. 14 or fig. 15 exemplarily illustrates that the starting time domain position of the first resource is earlier than the starting position of the second resource. Of course, the starting time domain position of the first resource may also be the same as the starting position of the second resource, and this is not specifically limited in this embodiment of the application.

It should be noted that fig. 14 or fig. 15 exemplarily illustrates that the (N + y 3) th target subframe after the WUS is delayed from being transmitted (postdone) in the x3 th to nth target subframes does not exceed the end position of the second resource. Of course, the (N + y 3) th target subframe after the WUS is delayed from being transmitted (postdone) on the (x 3) th to nth target subframes may exceed the end position of the second resource, and the processing manner at this time may refer to the processing manner in fig. 13 or fig. 14, and is not described herein again.

Optionally, in this embodiment of the application, for the scenario of delayed transmission (postdone), in order to avoid a problem that, after WUS on the x 3rd to N th target subframes is delayed for transmission (postdone), an end position of S2 target subframes after the y3 th target subframe may exceed an end position of the second resource to a next WUS resource, or may overlap with a gap between the WUS resource and a PO, or may overlap with a PO, or avoid a problem that, after the target subframe exceeding the end position of the second resource is discarded (drop), performance of the WUS may be affected, in this embodiment of the application, if the first resource and the second resource overlap in a time domain, a transmission position of the WUS may be moved forward, so that a time domain start position of the third resource may be advanced by K target subframes relative to the time domain start position of the second resource or the first resource, where K is the number of subframes of overlapping portions of the time domains of the first resource and the second resource, and K is a positive integer. This ensures that the end position of S2 target sub-frames after the y 3-th target sub-frame does not exceed the end position of the second resource after the WUS is delayed for transmission (postdone), thereby avoiding the problem that the end position of S2 target sub-frames after the y 3-th target sub-frame may exceed the end position of the second resource to the next WUS resource, or may overlap with the gap between the WUS resource and the PO, or may overlap with the PO after the WUS is delayed for transmission (postdone).

For example, the location profile of the first resource, the second resource, and the third resource may be as shown in fig. 16. Wherein S1 target subframes before the x3 th target subframe include K target subframes before the start position of the second resource, and K = y3-x3+1 from the first valid subframe of the second resource to the (x 3-1) th target subframe of the second resource; the S2 target-subframes after the y 3rd target-subframe include the (y 3+ 1) th target-subframe of the second resource to the nth target-subframe of the second resource, S1+ S2= N, S1= K + x3-1, S2= N-y3.

Alternatively, for example, the location distribution maps of the first resource, the second resource, and the third resource may be as shown in fig. 17. Wherein, the S1 target subframes before the x3 th target subframe include K target subframes before the start position of the second resource, and a first valid subframe of the second resource to an (N-K) th target subframe of the second resource, the S2 target subframes after the y3 th target subframe are 0, S1+ S2= N, S1= K + N-K = N, S2=0. It should be understood that when N is less than K, the S1 target-subframes preceding the x3 th target-subframe include N target-subframes preceding target-subframe a, which is K-N target-subframes preceding the starting position of the second resource, S1= N.

Alternatively, for example, the location distribution maps of the first resource, the second resource, and the third resource may be as shown in fig. 18. Wherein S1 target subframes before the x3 (x 3= 1) th target subframe include K target subframes before the start position of the first resource, K = y3; the S2 target-subframes after the y 3rd target-subframe include the (y 3+ 1) th target-subframe of the second resource to the nth target-subframe of the second resource, S1+ S2= N, S1= K, S2= N-y3.

Optionally, in this embodiment of the present application, when the time domain starting positions of the first resource and the second resource are overlapped (i.e., x3= 1), the time domain starting position of the third resource may be advanced by K target subframes relative to the time domain starting position of the second resource, which is not specifically limited in this embodiment of the present application.

It should be noted that, in this embodiment of the present application, the first target subframe to the nth target subframe of the second resource may also be understood as a target subframe on an actual duration of the WUS in an existing scenario where no downlink transmission interval resource is inserted into the WUS resource, for example, the target subframe on the actual duration of the WUS shown in fig. 1 a. Correspondingly, the resources from the first target subframe including the second resource to the nth target subframe including the second resource may also be defined as a fourth resource, where the fourth resource is a wake-up signal resource whose duration is less than or equal to the maximum duration of the WUS, and it can be understood that in the existing scenario where no downlink transmission interval resource is inserted into the WUS resource, the resource for transmitting the WUS is determined according to the actual duration of the WUS, for example, the resource for transmitting the WUS is determined according to the actual duration of the WUS shown in fig. 1a, which is herein described in detail again.

Optionally, in this embodiment of the application, if the number of target subframes on the overlapping resource in the time domain of the first resource and the second resource is large, for a scene one, the WUS may be greatly affected on the WUS detection performance after the WUS is discarded (drop). The influence on the WUS detection performance after the WUS is discarded (drop) can be reduced only when the number of target subframes on the overlapping resources of the first resource and the second resource on the time domain is small. Based on this, in the embodiment of the present application, if the first resource and the second resource overlap in the time domain, the network device may transmit the WUS in the delayed transmission (postbone) manner in the above scenario two when determining that the duration of the first resource is not less than the second threshold, and the terminal device may receive the WUS in the delayed transmission (postbone) manner in the above scenario two when determining that the duration of the first resource is not less than the second threshold; the network device may transmit the WUS according to a drop (drop) scheme in the first scenario if it is determined that the duration of the first resource is less than the second threshold, and the terminal device may receive the WUS according to a drop (drop) scheme in the first scenario if it is determined that the duration of the first resource is less than the second threshold. This may reduce the impact on WUS detection performance after WUS is dropped (drop).

Optionally, the second threshold on the terminal device side may be configured by a base station, and this is not specifically limited in this embodiment of the application. Of course, in this embodiment of the present application, the network device may also directly send a signaling to the terminal device to indicate whether the sending mode of the WUS of the terminal device is a delayed sending (postdone) mode or a drop (drop) mode, which is not specifically limited in this embodiment of the present application.

Based on the communication method provided by the embodiment of the present application, in the embodiment of the present application, if the second resource for transmitting the WUS overlaps with the downlink transmission interval resource in the time domain, the WUS is received or transmitted on part or all of the second resource except for the part overlapping with the first resource, and the WUS is not received or transmitted on the part overlapping with the second resource in the time domain, so that the downlink data or the downlink channel can be transmitted on the part overlapping with the first resource in the time domain, thereby reducing congestion of the downlink channel and reducing the influence on the scheduling of the network device (such as a base station).

The actions of the network device or the terminal device in steps S601 to S603 may be executed by the processor 301 in the communication apparatus 300 shown in fig. 3 calling the application program code stored in the memory 303 to instruct the network device to execute, which is not limited in this embodiment.

Optionally, in this embodiment of the present application, the network device may also determine the first resource, and further send the WUS on the third resource if the first resource and the fourth resource are overlapped in the time domain. The terminal device determines the first resource, and then receives the WUS on the third resource if the first resource and the fourth resource are overlapped on the time domain. Wherein the third resource is non-overlapping with the first resource in time domain. The first resource is a downlink transmission interval resource, and the fourth resource is a WUS resource with the duration less than or equal to the maximum duration of the WUS.

Optionally, in this embodiment of the application, if the first resource overlaps with the fourth resource in the time domain, the network device sends the WUS to the terminal device on the third resource, including: in the case where (P × maximum duration of WUS) is not less than (Q × first threshold), if the first resource and the fourth resource overlap in the time domain, the network device transmits WUS to the terminal device on the third resource, where P and Q are both positive integers. That is, in the embodiment of the present application, in the case where (P × maximum duration of WUS) is not less than (Q × first threshold), the network device further determines whether the first resource and the fourth resource overlap in the time domain; otherwise, in the case where (P × maximum duration of WUS) is less than (Q × first threshold), the network device considers that there is no first resource in the WUS transmission.

Optionally, in this embodiment of the application, if the first resource overlaps with the fourth resource in the time domain, the receiving, by the terminal device, the WUS from the network device on the third resource includes: in the case where (P × maximum duration of WUS) is not less than (Q × first threshold), if the first resource and the fourth resource overlap in the time domain, the terminal device receives WUS from the network device on the third resource, P and Q being positive integers. That is, in the embodiment of the present application, in the case where (the maximum duration of P × WUS) is not less than (Q × first threshold), the terminal device further determines whether the first resource and the fourth resource overlap in the time domain, and otherwise, in the case where (the maximum duration of P × WUS) is less than (Q × first threshold), the terminal device regards that there is no first resource in WUS transmission.

For example, the values of P and Q may both be 1; or P is 1, Q is a positive integer greater than 1; or Q is 1, and P is a positive integer greater than 1.

Of course, in the embodiment of the present application, the terminal device or the network device may also compare the lengths (R) of the first type (type-1) CSS _max ) Whether downlink transmission interval resources exist for the WUS is determined according to the first threshold, which is not specifically limited in the embodiment of the present application.

For specific description of the relative positions of the first resource, the second resource, the third resource, and the fourth resource, reference may be made to the specific description of the relative positions of the first resource, the second resource, and the third resource in the embodiment shown in fig. 6, and details are not repeated here.

Optionally, in the above embodiment of the present application, the wake-up signal is sent on the third resource, which may be understood as that the wake-up signal is sent according to a sequence of the target subframes on the third resource, for example, the wake-up signal on the target subframe i on the third resource is sent first, and then the wake-up signal on the target subframe i +1 on the third resource is sent, which is described in a unified manner and is not described in detail below.
