A communication system that supports direct communication between terminals and terminals, such as D2D communication, Machine to Machine (M2M) communication, or V2X (vehicle-to-everything) communication, is particularly suitable for performing link measurement between a terminal and a terminal. The communication system can also be applied to a network system that needs to perform link measurement between multiple network devices, for example, a wireless mesh network (wireless mesh network), a multi-hop network, etc., supporting multiple network devices.

If both UEs support simultaneous transmission and reception, each UE can be both a sender and a receiver. A UE can also perform D2D communication with multiple UEs at the same time, or multiple D2D communication can be performed simultaneously. For example, a D2D communication signal sent by one UE can be simultaneously received by multiple UEs, and one UE can also receive multiple UEs simultaneously. The D2D communication signal, at this time, different D2D links have data transmission at the same time. Of course, more UEs may be included in the communication system 100, and these UEs may or may not have D2D communication functions. In the embodiment of the present application, multiple UEs may be located under the coverage of the same base station, and served by the same base station.

For simplicity of description, the following embodiments of the present application are described with the first communication device as a network device (for example, a BS) and the second communication device as a user device, when the first communication device and the second communication device are other types. The communication device does not affect the application of the embodiment of the present application.

FIG. 2 is a communication method provided by an embodiment of the present application.

Optionally, in section 201, the first communications device configures T channel measurement periods for the N second communications devices, where N is an integer greater than or equal to 2, and T is an integer greater than or equal to 2. So that the second communication device transmits a signal on at least one of the T channel measurement periods according to the configuration information of the T channel measurement periods.

Optionally, the configuration of the T channel measurement periods may be static, that is, the first communication device and the second communication device preset the time domain resources occupied by the T channel measurement periods. The configuration of the T channel measurement period may also be semi-static or dynamic, that is, the first communication device may notify the configuration information of the T channel measurement period of the second communication device in a semi-static or dynamic manner. The semi-static notification manner refers to the configuration information that the first communication device notifies the T-channel measurement period of the second communication device according to the needs of the system, and the second communication is not updated by the first communication device. The device sends a signal according to the configuration information of the last notification; or the semi-static notification mode refers to the first communication device notifying the second communication device of the default configuration information of the T channel measurement period according to the need, and the first communication device does not update the configuration information. The second communication device sends a signal according to the default configuration information. When the first communication device re-notifies the new configuration information of the T channel measurement period of the second communication device according to the need, the second communication device is in the next T channel measurement period. The signal is sent according to the new configuration information, and then the signal is sent again according to the default configuration information. The dynamic notification mode means that the first communication device notifies the second communication device of the configuration information as needed, and the second communication device only transmits the signal according to the configuration information when receiving the configuration information.

Specifically, the configuration information of the T channel measurement periods may include: start position information of T channel measurement periods, length information of each measurement period in the T measurement periods, and at least period information of the T channel measurement periods. One. The configuration information may be through physical layer messages, for example, downlink control information (DCI), media access control (MAC) messages, for example, MAC (control element (MAC CE), radio resource control ( The radio resource control, RRC) message is sent, and the application does not limit this.

Taking FIG. 3 as an example, a possible channel measurement period configuration manner in the embodiment of the present application is given. Wherein, the value of T is 4, the axis of t is the time axis, UE1, UEN represents different UEs, and T1 to T4 represent 4 channel measurement periods. Each block (e.g., 301 or 302) in Figure 3 indicates whether a UE transmits a signal during a channel measurement period, wherein the shaded box indicates that the UE transmits a signal during the measurement period, and the unshaded box indicates The UE may receive or measure signals transmitted by other UEs during the measurement period, for example, block 301 indicates that the UEN transmits a signal during the measurement period T3, and block 302 indicates that UE0 may receive or measure other UE (eg, UE3) transmission during the measurement period T3. signal of. It should be noted that the UE represented by the unshaded box (such as 302) may not receive or measure the signal sent by other UEs during the measurement period, and whether the UE sends a signal during the period may be based on the BS. The scheduling is performed, and may also be arranged according to the UE's own requirements. For example, UE0 in FIG. 3 does not need to measure the signal of UE3 in the T3 measurement period, then UE0 may choose not to receive the signal of UE3, then UE0 may be in this period. The BS performs communication, for example, sending data to the BS or receiving data sent by the BS, and may also communicate with other UEs other than the UE1 to the UEN. In the embodiment of the present application, only the signal needs to be sent in each channel measurement period. The UE describes it and does not limit the specific behavior of other UEs. In the subsequent embodiments of the present application, the blocks of 301 and 302 in FIG. 3 are still used to describe the scheduling of different UEs in different measurement periods, and the meanings represented by each block refer to the above description, and details are not described herein.

The t0 time and the t1 time in FIG. 3 are respectively the start times of two sets of T channel measurement periods, and the BS can notify the UE of the absolute time value of t0 and/or t1, for example, x times y minutes z seconds q milliseconds, or Notifying the location of the UE t0 and/or t1 on the time axis based on a time unit partitioning rule of the communication system, for example, when notifying t0 and/or t1 based on the division of symbols, the BS may notify the UE that t0 and/or t1 is the xth The start time (or end time) of the symbol, where x is the symbol number or symbol index in the communication system. Of course, it can also be indicated based on a system-defined time unit such as slot or mini-slot or TTI or subframe. T0 and / or t1. The t_1 in FIG. 3 is the length of time occupied by one channel measurement period, and the BS may notify the UE of the absolute time length occupied by t_1, for example, x milliseconds, and may also notify the length of time occupied by t_1 based on the time unit division of the communication system. For example, t_1 is the length of x symbols (or time slots, mini-slots, subframes, TTI, etc.). Optionally, the time lengths of different channel measurement periods in the T channel measurement periods may be the same or different. In different cases, the value of t_1 may be different, and the BS may use a similar method to notify the UE of different t_1. Optionally, the channel measurement between the N UEs may be performed in a periodic manner, and the BS may further notify the UE of period information of each group of T channel measurement periods. T_0 in FIG. 3 represents a repetition period of each group of T channel measurement periods, and similar to t_1, the BS can notify the length information of the UE t_0 in different manners. Optionally, the T channel measurement periods may be continuous (for example, a group of T0 to T3 on the left side in FIG. 3), or may be discontinuous (for example, a group of T0 to T3 on the right side in FIG. 3) When the T channel measurement periods are not continuous, each channel measurement period may be separated by a certain duration, or may be a period of time between the partial channel measurement periods. When the T channel measurement periods are discontinuous, the BS may notify the UE of the interval duration between the channel measurement periods. As shown in FIG. 3, the BS may notify the duration of the UE t_2 or t_3, so that the UE can determine the channel measurement period. Interval, similar to t_1, the BS can inform the length information of the UE t_2 or t_3 in different manners. A person skilled in the art may know that, for the foregoing start time information, the length information of the measurement period, the period information, the interval information between the measurement periods, and the like, the BS may notify the UE by other forms and methods, which is not limited in this application. .

In an example, some of the N UEs may also obtain configuration information of the T channel measurement periods by receiving information sent by other UEs.

Optionally, the resource information includes frequency domain resource information and/or sequence information used to generate a signal. The number of resources available for the transmission channel may be the number of available frequency domain resources, or the number of sequences that can be used to generate the signal, or the number of combinations of the two, for example, when the number of available frequency domain resources is x, the number of sequences available and the generated signal is y, and the number after the combination of the two may be any value smaller than the product of x and y. The first communication device may notify all the available frequency domain resources of the second communication device and/or all available sequences for generating signals, and preset a combination relationship between the two, and the second communication device may be according to a preset combination. The relationship selects the frequency domain resource used to transmit the signal and the sequence used to generate the signal. In an example, the frequency domain resource information may be notified by using an available frequency domain bandwidth, an available frequency domain resource unit, a preset frequency domain comb structure, or the like, where the frequency domain resource unit may be divided according to system requirements.

It is known to those skilled in the art that the information of the frequency domain resources and the sequence resources can be performed in various manners, which is not limited in this application.

When it comes to the transmission of configuration information, the information involved in section 203 can also be sent simultaneously with the same signaling information as the part 201 involved. Similarly, in the flowcharts of the embodiments of the present application, the sequence of the steps may be adjusted, and the different steps may be combined, and the details are not described again.

In section 202, the first communications device schedules a second communications device in a different subset of the N second communications devices to transmit a signal during each of the T channel measurement periods. Optionally, the first communications device schedules a second communications device in the subset to transmit signals using different frequency domain resources and/or using different sequences for generating signals. Optionally, in different channel measurement periods, the second communication device that transmits the signal may use the same frequency domain resource and/or the same sequence for generating the signal. Optionally, the first communication device may notify each second communication device, one or several measurement periods that the second communication device should use when transmitting the signal, and resources used in the measurement periods, and N One or more measurement periods used by other communication devices in the communication device to transmit signals and resources used. The first communication device and the second communication device may also preset a subset division manner and a resource usage manner in different scenarios, so that the second communication device learns the configuration of the T channel measurement periods, and also obtains N The subset division manner of the second communication device and the resource usage manner, combined with the value of N and the identification information of each second communication device in the N second communication devices, can be used to learn when each UE transmits a signal. One or several measurement periods and the resources used.

Since the resources available in the communication network and the number of communication devices that need to perform mutual link measurement are all changing, the first communication device is required to perform the second communication based on the available resources and the need for mutual link measurement. The number of devices considers the specific resource allocation and scheduling of the second communication device. The specific scheduling mode provided in this embodiment will be described below with reference to specific drawings. For convenience of explanation, the following definitions are first made, where N represents the number of second communication devices that need to perform mutual link measurement, T represents the number of channel measurement periods required in one measurement period, and R represents a channel. The maximum number of resources available in the measurement period, which may be the number of frequency domain resources available in one channel measurement period, or the number of sequences of generated signals available in one channel measurement period, or a combination of the two. The number of available resources, which can be understood as the maximum number of second communication devices that can be signaled in one channel measurement period. N, T, and R are integers greater than or equal to 2. In the embodiment of the present application, the link measurement between every two second communication devices in the N second communication devices is involved, and therefore, the maximum available resource quantity R satisfies R=2 ^r (where r is greater than or equal to The relationship of the integers of 0, and the quantitative relationship between N and R, all affect the scheduling of the second communication device in different channel measurement periods. Therefore, in the embodiment of the present application, a specific scheduling manner is described according to whether R satisfies the relationship of R=2 ^r (where r is an integer greater than or equal to 0) and the relationship between N and R.

Scenario A1: When R=2 ^r (where r is an integer greater than or equal to 0), N=2R=2 ^r+1 , the first communication device can configure T=2log ₂ N=2 for N second communication devices (r+1) channel measurement periods.

At this time, the first communication device schedules, in each of the T channel measurement periods, a second communication device in a different subset of the N second communication devices to transmit a signal, the subset meeting: Each of the subsets includes less than or equal to N/2 second communication devices of the first group of second communication devices, and the first group of second communication devices included in each of the subsets does not All identical, and any one of the first set of second communication devices belongs to at least two different subsets, thereby ensuring that each of the N second communication devices has The opportunity receives signals from other N-1 second communication devices. The second communication devices in the two subsets are not identical, and the number of the second communication devices included in the two subsets is different, or at least one of the second communication devices included in one of the subsets is not included in the other a subset. In FIG. 4a, taking R=2, N=4, and T=4 as an example, a subset of N second communication devices that need to be scheduled in different measurement periods is given. Taking the first communication device as the BS and the second communication device as the UE, in the T0 period, the BS schedules the UE0 and the UE2 to perform signal transmission. In the T1 period, the BS schedules the UE1 and the UE3 to perform signal transmission. In the T2 period, the BS schedules the UE0. The signal is transmitted with UE1, and during the T3 period, the BS schedules UE2 and UE3 to perform signal transmission. A UE that is not scheduled in each measurement period may decide whether to receive a signal transmitted by the scheduled UE according to requirements, for example, whether it is required to measure a D2D link between itself and a UE that currently transmits a signal, or according to scheduling of the system. , thereby performing link measurement. In an example, after the configuration information of the T channel measurement periods is learned, any one of the N UEs may determine the scheduling manner as shown in FIG. 4a according to the characteristics of the second communication device subset, and further combine The value of N, the intra-group UE identity of the N UEs, and the available resources in each measurement period, and the usage rules of the available resources between the N UEs, determine the time period and resources that each UE should use to transmit signals. . In another example, the BS may notify the time period and resources used by each UE to transmit signals, and the time period and resources used by other UEs in the N UEs to transmit signals, and the UE only needs to perform signaling according to the notification of the BS and The signal can be received.

In one example, different UEs transmit signals using different frequency domain resources and/or sequences for generating signals during one channel measurement period. For example, in the T0 period, UE0 and UE2 may use the same frequency domain resource but different sequences for generating signals to transmit signals, and UE0 and UE2 may also use different frequency domain resources but the same sequence for generating signals. Signals, UE0 and UE2 may also transmit signals using different frequency domain resources and different sequences for generating signals. In an example, UEs in different subsets may use the same resource or different resources in different channel measurement periods, for example, resources used by UE0 and UE2 in the T0 period and UE1 and UE3 used in the T1 period. Resources can be the same, they can be different or completely different. In a specific example, the UE may determine a resource to be used for transmitting a signal according to a preset resource selection principle, and determine a resource location that needs to receive a signal. For example, each frequency domain resource may have a frequency domain resource identifier, and each user generated signal sequence may also have a sequence identifier. When the UE determines the resource, the UE may determine the combination of the frequency domain resource identifier and the sequence identifier. The resource identifier used or the resource identifier that needs to receive the signal. For example, if the available frequency domain resource identifier is (1, 2) and the available sequence identifier is (3, 4), the available resource identifiers are ID1=(1,3), ID2=(1,4), ID3= (2,3), ID4=(2,4). The UE identifier and the resource identifier may be preset in a corresponding relationship. For example, the UE with the UE identifier of 1 may use the resource indicated by the ID1, and the user with the UE identifier 2 may use the resource indicated by the ID2, the specific UE identifier and the resource identifier. The correspondence can be set according to requirements, and this application does not limit.

It should be noted that, for the sake of brevity of the drawing, the lengths of T0 to T3 in FIGS. 4a-4b are the same and continuous, but in practical applications, T0 to T3 may be measurement periods of different lengths, or may be discontinuous, and they are mutually For the relationship and the specific configuration manner, reference may be made to the description of the channel measurement period in FIG. The descriptions of the channel measurement periods in FIG. 3 can be referred to in FIG. 3 for the characteristics and configuration manners of the T channel measurement periods in the embodiment of the present application, and details are not described herein again.

Scenario A2: When R=2 ^r (where r is an integer greater than or equal to 0), N<2R, the first communication device can configure T=2log ₂ N=2(r+1) for N second communication devices. Channel measurement period.

In this scenario, the first communication device and the second communication device can still divide the subset of N'=2R= ^2r+1 second communication devices according to the subset division manner in the scenario A1, except that For each measurement period, only the second communication device belonging to the N second communication devices in each subset may be scheduled. In FIG. 4b, taking R=2, N=3, and T=4 as an example, a subset of N second communication devices that need to be scheduled in different measurement periods is given. As shown in FIG. 4a and FIG. 4b, when three UEs are scheduled, the subset of the UEs can still be divided according to four UEs. In actual scheduling, only the scheduling of the fourth UE (UE3) needs to be removed. For a specific scheduling implementation manner, refer to the description in scenario A1.

Scene B1: When R=2 ^r +1 (where r is an integer greater than or equal to 0), N ≤ 2 ^r+1 , the first communication device can use 2 ^r of the R resources for N second communications The device configuration T=2log ₂ N=2(r+1) channel measurement periods. For details about the configuration and scheduling mode, refer to the description in scenario A1 or scenario A2.

Scene B2: When R=2 ^r +1 (where r is an integer greater than or equal to 0), 2 ^r+1 <N ≤ 2 ^r+1 + r+1, the first communication device can perform N second communications N ₁ = 2 ^r+1 second communication devices (referred to as the first group of second communication devices) in the device are scheduled using 2 ^r resources according to the situation of scenario A1, which is N ₂ of the N second communication devices. =r+1 second communication devices (denoted as the second group second communication device) are scheduled using 1 resource, and T=2log ₂ N ₁ =2(r+1) is configured for the N second communication devices Channel measurement period, where N = N ₁ + N ₂ .

At this time, the first communication device schedules, in each channel measurement period of the T channel measurement periods, a second communication device in a different subset of the N second communication devices to transmit a signal, the subset Satisfying: each of the subsets includes less than or equal to N1/2 second communication devices of the first group of second communication devices, and the first group of second communications included in each of the subsets The devices are not identical, and any one of the first set of second communication devices belongs to at least two different subsets, and any one of the second set of second communication devices is second The communication devices each belong to at least two different subsets, and at least two subsets of any one of the second group of second communication devices belong to the second group of second communication devices The other subset of the second communication devices are different, and the two subsets to which the second group of second communication devices belong include all of the second communication devices of the first group of second communication devices. The first communication device schedules a different subset of the second communication device that meets the above conditions to transmit signals in each time period, and can ensure that each of the N second communication devices has an opportunity to receive other N-1 Signals transmitted by the second communication device, thereby ensuring that each of the first group of second communication devices can implement link measurement between the two, and each second of the second group of communication devices The communication device can also implement link measurement between the two and the second communication device of the first group of second communication devices. In FIG. 5a, taking R=3, N=6, and T=4 as an example, a subset of N second communication devices that need to be scheduled in different measurement periods is given. In this example, N=2 ^r+1 +r+1, N ₁ =4, N ₂ =2, UE0 to UE3 belong to the first group of second communication devices, and UE4 and UE5 belong to the second group of second communication devices. For UE0 to UE3, the scheduling of the BS in different measurement periods uses the scheduling manner in scenario A (in this example, the same as the case shown in FIG. 4a), for UE4 and UE5, only UE4 can be scheduled in each measurement period. And one of UE5, and each of UE4 and UE5 is scheduled at least twice (ie, belongs to at least two of the subsets), and in the at least two schedulings, UE0 to UE3 (first group Each UE in the two communication devices must transmit a signal to ensure that UE4 and UE5 have the opportunity to receive the signals transmitted by each of UE0 to UE3, and also ensure that each UE in UE4 and UE5 transmits The signals have a chance to be received by each of UE0 to UE3. In FIG. 6a, a case of R=5, N=11, and T=6 is taken as an example, and a subset of N second communication devices that need to be scheduled in different measurement periods is given. In this example, N=2 ^r+1 +r+1, N ₁ =8, N ₂ =3, UE0 to UE7 belong to the first group of second communication devices, and UE8 to UE10 belong to the second group of second communication devices. For UE0 to UE7, the scheduling of the BS in different measurement periods uses the scheduling mode in scenario A. For UE8 to UE10, only one of UE8 to UE10 may be scheduled in each measurement period, and each of UE8 to UE10 shall be scheduled at least twice (ie, belong to at least two of the subsets), and In this at least two scheduling, each of UE0 to UE7 (the first group of second communication devices) has to transmit a signal to ensure that each UE in UE8 to UE10 has the opportunity to receive UE0 to UE7. The signal transmitted by each UE can also ensure that the signals transmitted by each of the UE8 to the UE 10 have a chance to be received by each of the UE0 to the UE7. In FIG. 5b and FIG. 5c, taking R=3, N=5, and T=4 as an example, a subset of N second communication devices that need to be scheduled in different measurement periods are given. In this example, N<2 ^r+1 +r+1, N ₁ =4, N ₂ =1, UE0 to UE3 belong to the first group of second communication devices, and UE4 belongs to the second group of second communication devices. In FIG. 5b, UE4 belongs to 2 subsets, and sends signals in the T0 and T1 periods respectively, so that each UE in UE0 to UE3 has the opportunity to receive the signal sent by UE4, and UE4 has the opportunity to receive UE0 in the T2 and T3 periods. Signals sent to each UE in UE3. The UE4 in FIG. 5c belongs to three subsets, and transmits signals at T0, T2, and T3, respectively. In this case, all UEs in UE0 to UE3 can receive the signal sent by UE4 in two periods of T2 and T3, T0. When UE4 sends a signal, UE1 and UE3 can receive, so as to enhance the reliability of UE4 signal measurement, UE4 has the opportunity to receive the signals sent by UE1 and UE3 in the T1 period. If UE4 can achieve full duplex, then The signals transmitted by UE0 and UE2 are accepted at other times. In FIG. 6b, taking R=5, N=9, and T=6 as an example, a subset of N second communication devices that need to be scheduled in different measurement periods is given. In this example, N<2 ^r+1 +r+1, N ₁ =8, N ₂ =1, UE0 to UE7 belong to the first group of second communication devices, and UE8 belongs to the second group of second communication devices. For UE0 to UE7, the scheduling of the BS in different measurement periods uses the scheduling mode in scenario A, and for UE8, its transmission signal is scheduled in the T0 and T1 periods.

FIG. 7 is another communication method provided by an embodiment of the present application.

Optionally, in part 701, the first communications device configures T channel measurement periods for the N second communications devices.

In 702, the first communications device schedules a second communications device in a different subset of the N second communications devices to transmit a signal during each of the T channel measurement periods.

Optionally, in part 703, the first communications device may further send, to the at least one second communications device of the N second communications devices, at least one of the following information: the number of resources information available for transmitting signals in each measurement period And resource information that can be used to transmit a signal, numerical information of N, and identification information of the at least one second communication device.

For specific implementations of Sections 701 through 703, reference may be made to the embodiments of Sections 201 through 203 above.

When the communication network contains more second communication devices that need to perform link measurement between each other, but there is no more available resources, the first communication device needs to configure more for the second communication device. The channel measurement period ensures the link measurement between two of the plurality of second communication devices. For the above scenario, the communication method corresponding to FIG. 7 may further include a 704 part and a 705 part.

Optionally, in 704, the first communications device schedules, among the M channel measurement periods, each of the M second communication devices except the N second communications devices. A second communication device in a different subset of the second communication device transmits a signal, wherein the K channel measurement periods are configured by the first communication device for the other MN second communication devices, and the K The channel measurement period does not coincide with the T channel measurement periods, K is an integer greater than or equal to 1, and at least one of the K channel measurement periods is used for at least one of the N second communication devices The second communication device receives a signal transmitted by at least one of the other MN second communication devices. The N second communication devices are part of M second communication devices, and M is an integer greater than N. The K channel measurement period does not coincide with the T channel measurement periods, which means that any one of the K channel measurement periods is not included in the T channel measurement periods. Optionally, the K channel measurement period may also be used for link measurement between the other MN second communication devices, where the first communication device configures K channel measurement periods for the MN second communication devices. For a specific implementation manner of the MN second communication devices in the K channel measurement period, the specific implementation manner in the embodiment corresponding to FIG. 2 may also be applied. Optionally, configuring, by the first communications device, the K channel measurement periods for the MN second communications devices may be performed simultaneously with the 701 portion, or may be performed before the 701 portion, and configuring the K channel measurement periods is if the configuration information is sent. The configuration information of the T channel measurement periods in the 701 part may also be sent using the same signaling or message. If it is necessary to transmit the resource information involved in the K channel measurement periods, it may also be transmitted using the same signaling or message as the message in the 703 part. Optionally, the first communications device may further send configuration information of the K channel measurement periods to the N second communications devices, so that the N second communications devices receive the MNs according to requirements or according to scheduling. The signal transmitted by the second communication device.

Optionally, in step 705, the first communications device sends the value information of the M to at least one of the N second communications devices. The N second communication devices may determine, according to the value of M and a preset subset division manner, a scheduling manner of the first communication device to the MN second communication devices in the K channel measurement periods, thereby The scheduling receives signals transmitted by the MN second communication devices.

In the following, the specific scheduling modes provided in this embodiment are described in conjunction with the definitions of R, T, and N in the foregoing. Wherein the N second communication devices are part of the M second communication devices, and at least one of the N second communication devices needs to be the other MN of the M second communication devices At least one of the two communication devices performs link measurement between each other.

Scenario A3: When R=2 ^r (where r is an integer greater than or equal to 0), N≤2R, M>2R, the first communication device may configure T=2log ₂ N=2 for the N second communication devices ( r+1) channel measurement periods, K channel measurement periods are configured for the remaining MN second communication devices. The K channel measurement periods do not coincide with the T channel measurement periods, such that at least one of the N second communication devices can receive at least one of the remaining MN second communication devices on at least one of the K channel measurement periods A signal sent by a communication device.

At this time, the scheduling manner of the N second communication devices by the first communication device may use the scheduling manner in the scenario A1 or the scenario A2 on the T channel measurement periods according to the relationship between N and R. The scheduling manner of the second communication device to the remaining M-N second communication devices may also use the scheduling manner in the scenario A1 or the scenario A2 on the K channel measurement periods according to the relationship between the M-N and the R. Optionally, the first communications device may notify the at least one of the N second communications devices to receive the signal sent by the at least one of the MN second communications devices on the at least one of the K channel measurement periods . Specifically, the first communications device may notify at least one of the N second communications devices, configuration information of the K channel measurement periods, resource information in each of the K channel measurement periods, and K channel measurements. At least one of a second communication device that transmits a signal on each measurement period in the period, and a resource used when the second communication device transmits a signal, so that at least one of the N second communication devices A signal transmitted by at least one of the remaining MN second communication devices may be received in at least one of the K channel measurement periods. Certainly, the N second communication devices may also learn, by using a preset manner, a second communication device that sends a signal on each of the K channel measurement periods and a used resource, for example, a second The communication device may determine, according to a preset subset division principle, the second communication device that transmits the signal on each of the K channel measurement periods and the used resource in combination with the numerical information of the M.

In Fig. 8a, taking R=2, M=8, N=4, T=4, and K=4 as an example, a second communication device that needs to be scheduled in different measurement periods is given. In this example, UE0 to UE3 belong to the Nth second communication devices, UE4 to UE7 belong to the remaining MN second communication devices, T0 to T3 are the T channel measurement periods, and T4 to T7 are the K Channel measurement period. The scheduling mode of UE0 to UE3 in T0 to T3 is the scheduling mode of scenario A1, and the scheduling mode of UE4 to UE7 in T4 to T7 is also the scheduling mode of scenario A1. Each of the UE0 to UE3 has an opportunity to receive a signal transmitted by each of the UE4 to the UE7 in the T4 to T7 period, and each of the UE4 to the UE7 also has an opportunity to receive the UE0 to the T0 to T3 period. The signal transmitted by each UE in UE3, so that the link between every two UEs in the M UEs can be measured. In an example, one or more UEs of UE0 to UE3 may not need to receive signals sent by all UEs in UE4 to UE7, and the one or more UEs may not need to receive in each period of T4 to T7. The period of the signal sent by the UE in the UE4 to the UE7 does not need to receive the signal sent by the UE in the UE4 to the UE7 can be used for transmission of other service data, thereby improving resource utilization. For example, UE0 may only need to receive the signal sent by UE4, UE0 may receive the signal sent by UE4 at T4 and/or T6, and UE0 may perform other service data transmission in other periods. For another example, after two periods of T4 and T5, each UE of the UE0 to the UE3 has an opportunity to receive the signal sent by each of the EU4 to the UE7. If the measurement is completed at this time, the UE0 to the UE3 are at the T6. Other business data can also be transferred during the T7 period. In FIG. 8b, taking R=2, M=5, N=4, T=4, and K=1 as an example, a second communication device that needs to be scheduled in different measurement periods is given. In this example, UE0 to UE3 belong to the Nth second communication devices, UE4 belongs to the remaining MN second communication devices, T0 to T3 are the T channel measurement periods, and T4 is the K channel measurement period. . The scheduling mode of the UE0 to the UE3 in the T0 to T3 is the scheduling mode of the scenario A1, and the scheduling mode of the UE4 in the T4 is the scheduling mode of the scenario A2. The UE4 may receive the signals transmitted by each of the UE0 to the UE3 in the T0 to T3 period, and each of the UE0 to the UE3 may receive the signal transmitted by the UE4 at the T4, thereby completing the chain between the two UEs in the M UEs. Road measurement.

Scene B3: When R=2 ^r +1 (where r is an integer greater than or equal to 0), 2 ^r+1 <N≤2 ^r+1 +r+1, M>2 ^r+1 +r+1, The first communication device may configure T channel measurement periods for the N second communication devices and K channel measurement periods for the remaining MN second communication devices. The K channel measurement periods do not coincide with the T channel measurement periods, such that at least one of the N second communication devices can receive at least one of the remaining MN second communication devices on at least one of the K channel measurement periods A signal sent by a communication device.

At this time, the scheduling manner of the N second communication devices by the first communication device may use the scheduling manner in the scenario B2 on the T channel measurement periods according to the relationship between N and R. The scheduling manner of the second communication device to the remaining M-N second communication devices may also use the scheduling mode in the scenario B1 or the scenario B2 on the K channel measurement periods according to the relationship between the M-N and the R. Similar to the A3 scenario, at least one of the N second communication devices may also determine a scheduling manner of the remaining MN second communication devices by scheduling or a preset manner of the first communication device, thereby A signal transmitted by at least one of the remaining MN second communication devices is received on the K channel measurement periods.

In Fig. 9a, taking R=3, M=12, N=6, T=4, and K=4 as an example, a second communication device that needs to be scheduled in different measurement periods is given. In this example, UE0 to UE5 belong to the N second communication devices, UE6 to UE11 belong to the remaining MN second communication devices, T0 to T3 are the T channel measurement periods, and T4 to T7 are the K Channel measurement period. The scheduling mode of UE0 to UE5 in T0 to T3 is the scheduling mode of scenario B2, and the scheduling mode of UE6 to UE11 in T4 to T7 is also the scheduling mode of scenario B2. In Fig. 9b, taking R=3, M=9, N=6, T=4, and K=4 as an example, a second communication device that needs to be scheduled in different measurement periods is given. In this example, UE0 to UE5 belong to the Nth second communication devices, UE6 to UE8 belong to the remaining MN second communication devices, T0 to T3 are the T channel measurement periods, and T4 to T7 are the K Channel measurement period. The scheduling mode of the UE0 to the UE5 in the T0 to the T3 is the scheduling mode of the scenario B2, and the scheduling mode of the UE6 to the UE11 in the T4 to T7 is the scheduling mode of the scenario B1. The manner of receiving signals between the N second communication devices and the M-N second communication devices is similar to that described in FIG. 8a and FIG. 8b, and details are not described herein again.

FIG. 10 is still another communication method provided by an embodiment of the present application.

Optionally, in part 1001, the first communications device configures T channel measurement periods for the N second communications devices.

In part 1002, the first communications device schedules a second communications device in a different subset of the N second communications devices to transmit a signal during each of the T channel measurement periods.

Optionally, in part 1003, the first communications device may further send, to the at least one second communications device of the N second communications devices, at least one of the following information: the number of resources available for transmitting signals in each measurement period And resource information that can be used to transmit a signal, numerical information of N, and identification information of the at least one second communication device.

Specific embodiments of Sections 1001 through 1003 can be referred to the embodiments of Sections 201 through 203 above.

When the number of resources R available for link measurement between the second communication devices in the communication network does not satisfy R=2 ^r or R=2 ^r +1, the first communication device may group R, so that The number of resources included in each resource group satisfies R(i)=2 ^r or R(i)=2 ^r +1, where R(i) represents the maximum number of available resources in the i-th resource group, and i is greater than An integer equal to 0. It should be noted that R(i) only represents the number of resources. A specific resource may belong to one of R(i) in one channel measurement period, and may belong to R in another channel measurement period. One of (j), that is, only the maximum number of available resources of the same group of resources is the same in different channel measurement periods, and the specific available resources included in the group of resources may be different in different channel measurement periods. Then, according to the total number M of the second communication devices that perform link measurement between the two, a corresponding second communication device number N(i) is allocated to each group of R(i) resources, and the scenario in the above embodiment is used. At least one of A1, scenario A2, scenario A3, scenario B1, scenario B2, and scenario B3 configures a channel measurement period T(i) for each group of N(i) second communication devices, respectively.

It also belongs to one of the N(i) second communication devices. Where N(i) represents the number of second communication devices that use R(i) resources to transmit signals, and ∑ _i N(i)=M, T(i) indicates that the first communication device is N(i) The second communication device uses the number of channel measurement periods configured by the R(i) resource transmission signals.

In this case, R is divided into two groups of R(1) and R ( 2). If R(1) and/or R(2) still do not satisfy R(i)=2 ^r and R(i)=2 ^r +1 is not satisfied, then R(1) and/or R(2) may also be used. Continue to group, get R (3), R (4)...., the corresponding M will also be divided into N (1), N (2), N (3), N (4) .... When R is divided into more than two groups, the configuration and scheduling mode of each group of R(i) resources, N(i) and T(i) is not substantially different from the configuration and scheduling mode when R is divided into two groups. In the embodiment of the present application, the example in which R is divided into two groups is taken as an example.

In an example, when R does not satisfy R(i)=2 ^{r and} does not satisfy R(i)=2 ^r +1, the first communication device may group R into R(1)=floor(R/2). And R(2)=RR(1), where floor() represents rounding down. If R(1) and/or R(2) still do not satisfy R(i)=2 ^r and R(i)=2 ^r +1 is not satisfied, then R(k)=floor(R(j) can continue to be used. /2) and R(p)=R(j)-R(k) are grouped by R(1) and/or R(2), where j=1 or 2. If R(k) and/or R(p) still do not satisfy 2 ^r and 2 ^r +1 is not satisfied, then R(k) and/or R(p) can be continued using the same method as for R(1) grouping. ) grouping.
