Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

It should be understood that the manner, the case, the category, and the division of the embodiments are only for convenience of description and should not be construed as a particular limitation, and features in various manners, the category, the case, and the embodiments may be combined without contradiction.

It should also be understood that "first", "second", and "third" in the embodiments of the application are merely for distinction and should not constitute any limitation to the application.

It should also be understood that, in the various embodiments of the present application, the sequence numbers of the processes do not mean the execution sequence, and the execution sequence of the processes should be determined by the functions and the inherent logic of the processes, and should not constitute any limitation to the implementation process of the embodiments of the present application.

It should also be understood that the solution of the present application can be applied to various communication systems, such as: a global system for mobile communications (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a long term evolution (long term evolution, LTE) system, an Advanced long term evolution (LTE-a) system, a universal mobile telecommunications system (universal mobile telecommunications system, UMTS), a next generation communication system (e.g., a fifth generation communication (5G) system), a converged system of multiple access systems, or an evolved system, etc. Among them, the 5G system may also be referred to as a new radio access technology (NR) system.

In the embodiment of the present application, a network device is an apparatus deployed in a radio access network to provide a wireless communication function for a terminal device. The network device may include various forms of base stations, macro base stations, micro base stations (also called small stations), relay stations, access points, new radio controllers (NR controllers), centralized network elements (centralized units), radio remote modules (rfs), distributed network elements (distributed units), reception points (TRPs) or Transmission Points (TPs), or any other wireless access devices, but the embodiments of the present application are not limited thereto. In systems using different radio access technologies, the names of devices with base station functions may be different. For example, the network device may be an Access Point (AP) in a Wireless Local Area Network (WLAN), and may also be an evolved node B (eNB or eNodeB) in an LTE system. Alternatively, the network device may also be a node b (node b) of a third generation (3rd generation, 3G) system, and in addition, the network device may also be a relay station or an access point, a vehicle-mounted device or a network device in a fifth generation communication (5G) network in the future or a network device in a Public Land Mobile Network (PLMN) network in the future, and the like.

In embodiments of the present application, the terminal device may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem with wireless communication capabilities. The terminal device may be a device in a communication system (e.g., 5G) accessing a network side through a network device (e.g., NR or TRP), which may also be referred to as a User Equipment (UE), and is a device providing voice and/or data connectivity to a user, for example, a handheld device with a wireless connection function, a vehicle-mounted device, and the like. Common terminals include, for example: the mobile phone includes a mobile phone, a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), and a wearable device such as a smart watch, a smart bracelet, a pedometer, and the like.

In a new generation radio access (NR) system, a user specific (UE specific) scheme is introduced to transmit a measurement signal. Alternatively, the measurement signal may be a channel Sounding Reference Signal (SRS).

That is, the terminal device is able to transmit measurement signals specific to the terminal device, i.e., the terminal device may transmit measurement signals specific to the terminal device.

The terminal device-specific measurement signal may also be referred to as a "UE specific measurement signal". For ease of explanation, the dedicated measurement signal may be referred to as a "dedicated measurement signal". The dedicated measurement signals sent by different terminal devices are different. Wherein the difference of the measurement signals may comprise at least one of the following conditions:

case # 1: if the sequences of the two measurement signals are different, the two measurement signals can be considered to be different.

For example, assume that the sequence of the dedicated measurement signal transmitted by terminal apparatus # a is sequence # a, the sequence of the dedicated measurement signal transmitted by terminal apparatus # B is sequence # B, and the sequence # a and the sequence # B are different sequences.

Case # 2: if the scrambling codes used to transmit the two measurement signals are different, the two measurement signals may be considered different.

For example, assume that the scrambling code used by terminal apparatus # C to transmit the dedicated measurement signal is # C, the scrambling code used by terminal apparatus # D to transmit the dedicated measurement signal is # D, and the scrambling code # C and the scrambling code # D are different scrambling codes.

Case # 3: if the cyclic shifts used to transmit the two measurement signals are different, the two measurement signals may be considered different.

For example, assume that terminal apparatus # E transmits a dedicated measurement signal using a cyclic shift of # E, and terminal apparatus # F transmits a dedicated measurement signal using a cyclic shift of # F, which are different cyclic shifts.

Similarly, the two measurement signals are the same, which includes various situations. For example, in case #1, if the sequences of two measurement signals are identical, the two measurement signals can be considered to be identical. In case #2, if the scrambling codes used to transmit the two measurement signals are the same, the two measurement signals can be considered to be the same. In case #3, if the cyclic shift used to transmit the two measurement signals is the same, the two measurement signals can be considered to be the same.

Based on the above, the terminal device may transmit the dedicated measurement signal through at least one of various schemes.

As an alternative example, the terminal device may generate a dedicated measurement signal using a sequence (i.e., a dedicated sequence) that is dedicated to the terminal device. In other words, the sequence of the dedicated measurement signal transmitted by the terminal device is a sequence dedicated to the terminal device. The sequence of the dedicated measurement signals transmitted by different terminal devices is different.

As an alternative further example, the terminal device may generate a dedicated measurement signal using a scrambling code that is specific to the terminal device (i.e. a dedicated scrambling code). In other words, the scrambling code used by the terminal device to transmit the dedicated measurement signal is the scrambling code dedicated to that terminal device. The scrambling codes used by different terminal devices for transmitting the dedicated measurement signals are different.

As an alternative further example, the terminal device may generate the dedicated measurement signal using a cyclic shift (i.e. a dedicated cyclic shift) dedicated to the terminal device. In other words, the cyclic shift used by the terminal device to transmit the dedicated measurement signal is a cyclic shift dedicated to the terminal device.

The special measurement signal is introduced, so that the network equipment serving the terminal equipment can effectively identify the terminal equipment, the network equipment can obtain information related to the characteristics of the terminal equipment, and the network equipment can effectively measure the measurement signal.

It should be understood that measuring the measurement signal at a receiving end (e.g., a network device) of the measurement signal may include: the apparatus determines at least one of a Reference Signal Received Power (RSRP), a Reference Signal Received Quality (RSRQ), a Channel Quality Indicator (CQI), a Channel State Information (CSI), and a Received Signal Strength Indicator (RSSI) by receiving the measurement signal. Optionally, the measuring the measurement signal by the receiving end (e.g., the network device) of the measurement signal may further include: the device estimates the area or orientation in which the transmitting end that transmitted the measurement signal is located, either by angle-of-arrival (AOA) estimation or by beam group scanning.

In order to improve the communication efficiency, not only the network device serving the terminal device has a need to measure the measurement signal, but also other devices may have a need to measure the measurement signal of the terminal device.

For example, in the communication system, assuming that the terminal apparatus # a is transmitting a signal in the uplink, there may be other apparatuses receiving a signal in addition to the network apparatus #1 serving the terminal apparatus # a receiving a signal in the uplink. For example, terminal apparatus # B is receiving a signal transmitted downstream by network apparatus # 2. When receiving the signal transmitted in the downlink of the network device #2, the terminal device # B may receive the signal transmitted in the uplink of the terminal device # a, which may cause the uplink transmission signal of the terminal device # a to interfere with the downlink reception signal of the terminal device # B, and may easily cause the downlink reception signal of the terminal device # B to fail.

For this scenario, if the interference from the terminal # a to the terminal # B is strong, when the network device #2 knows that the terminal # a transmits the uplink signal, the network device #2 may not schedule the terminal # B to receive the downlink signal, or the network device #2 may schedule the terminal # B to receive the signal on the resource that is not overlapped with the uplink transmission of the terminal # a, so as to avoid the interference from the terminal # a to the terminal # B. That is, the network device #2 needs to obtain interference information of the terminal device # a to the terminal device # B for scheduling the terminal device # B. This requires terminal apparatus # B to measure the measurement signal transmitted from terminal apparatus # a.

Similarly, the terminal # a uplink transmission signal may also interfere with the uplink reception of the network device #2, and the terminal # a uplink transmission signal may also interfere with the downlink reception signals of other terminal devices in the cell.

Therefore, not only the network device serving the terminal device has a need to measure the measurement signal transmitted by the terminal device, but also other devices may have a need to measure the measurement signal transmitted by the terminal device.

As can be seen from the above, the NR system introduces the dedicated measurement signal, and the terminal apparatus # a transmits the dedicated measurement signal, and it is difficult for other apparatuses such as the network apparatus #2 and the terminal apparatus # B which do not serve the terminal apparatus # a to recognize the dedicated measurement signal transmitted by the terminal apparatus # a, and thus the dedicated measurement signal transmitted by the terminal apparatus # a cannot be accurately measured.

Therefore, how to transmit the measurement signal by the terminal device to meet the measurement requirements of different devices becomes an urgent technical problem to be solved.

Based on the above, the embodiment of the present application provides a communication method, which is beneficial to meeting the measurement requirements of different devices on measurement signals sent by a terminal device.

Network device 101 may communicate with terminal device 102 and terminal device 103. The application scenario may also include a network device 104 and a terminal device 105 located within the coverage area of the network device 104. It should be understood that the application scenario may also include more terminal devices located within the coverage of the network device 101, and more terminal devices located within the coverage of the network device 101.

The time unit may also be a plurality of subframes, a plurality of slots, a plurality of minislots, or a plurality of symbols, etc. Further, the time unit may be a time unit for scheduling a transport block in the communication system. For example, the time unit may be a Transmission Time Interval (TTI).

The transmission direction is as follows: in the embodiment of the present application, the transmission direction at least includes uplink transmission and downlink transmission. The transmission direction may further include at least one of null (empty) undetermined (unknown) and reserved (reserved). The uplink transmission in the transmission direction means that the terminal device sends data to the network device. The transmission direction is downlink transmission, which means that the network device sends data to the terminal device. A transmission direction null can be understood as: no data transfer takes place. For example, assuming that the transmission direction of subframe #1 is null, it can be understood that data is not transmitted on subframe #1, and this subframe #1 is a null resource, which can be used for interference measurement, e.g., for cross-interference link measurement. The transmission direction is unknown/reserved, which is understood to be unknown, mainly for forward compatibility considerations. For example, the subframe or slot with the transmission direction of unknown/reserved may be used for Device-to-Device (D2D) communication, measurement, and the like.

Non-uplink transmission: the transmission direction is non-uplink transmission, which can be understood as: the transmission direction is downlink transmission, null, unknown or reserved.

Non-downlink transmission: the transmission direction is non-downlink transmission, which can be understood as: the transmission direction is uplink transmission, null, unknown or reserved.

Bandwidth part (bandwidth part, BP): in this embodiment, the BP may be a continuous segment of resources in the frequency domain. For example, one bandwidth part contains consecutive K (K >0) subcarriers; or, one bandwidth part is a frequency domain resource where K (K >0) non-overlapping continuous Resource Blocks (RBs) are located; alternatively, a bandwidth part is a frequency domain resource where M (M >0) non-overlapping consecutive Resource Block Groups (RBGs) are located, and an RBG includes P (P >0) consecutive RBs.

The neighboring network device: there is a common coverage area between two network devices, which may be considered adjacent network devices. Or the distance between the two network devices is smaller than the preset threshold, the two network devices can be considered as adjacent network devices.

Dedicated measurement signals: the dedicated measurement signal may refer to a measurement signal dedicated to a certain terminal device (or a measurement signal dedicated to a certain terminal device). The specific measurement signals sent by different terminal devices are different, and the detailed description of the specific measurement signals may refer to the above related description, which is not described herein for brevity.

Common measurement signal: the common measurement signal may refer to a measurement signal common to a plurality of terminal devices. That is, a plurality of terminal apparatuses can transmit the same measurement signal, which is a measurement signal common to the plurality of terminal apparatuses. The common measurement signal may be implemented in a number of ways.

For example, the same sequence, i.e., a common sequence, may be configured for a plurality of terminal devices. The common sequence is the measurement signal. Any terminal device of the plurality of terminal devices transmits the common sequence, which may be considered to transmit a common measurement signal. As an optional example, different time-frequency resources may be configured for the plurality of terminal devices. As another optional example, the same time-frequency resource may be configured for the multiple terminal devices, and different cyclic shifts may be configured for the multiple terminal devices.

For another example, the same scrambling code, that is, a common scrambling code (a measurement signal transmitted using the common scrambling code is a common measurement signal) may be configured for a plurality of terminal apparatuses. Any one of the plurality of terminal devices transmits the common sequence by the common scrambling code, and the terminal device can be considered to transmit a common measurement signal.

Alternatively, the plurality of terminal devices may be terminal devices under coverage of one TRP. Alternatively, the common measurement signal may be a TRP-specific (specific) measurement signal. That is, a plurality of terminal devices belonging to one TRP may transmit the same measurement signal (or sequence). The TRP-specific measurement signal is the same measurement signal transmitted by the plurality of terminal devices.

The common sequence of the TRP is known to other TRPs. At least one of the plurality of terminal devices may transmit the common sequence (i.e., transmit a common measurement signal) so that a receiving end of the common sequence measures the common sequence.

Alternatively, the plurality of terminal devices may be terminal devices under the coverage of one cell. Alternatively, the common measurement signal may be a cell specific measurement signal. That is, a plurality of terminal apparatuses belonging to one cell may transmit the same measurement signal (or sequence). The cell-specific measurement signal is the same measurement signal transmitted by the plurality of terminal devices.

First type measurement signal: a first type of measurement signal may be understood as a type of measurement signal. Each of the at least one terminal device may transmit a measurement signal of the type. Optionally, the first type measurement signal may be used for the network device of the local cell to perform measurement. Taking the communication scenario 100 as an example, the first type measurement signal sent by the terminal device 102 may be used for the network device 101 to perform measurement, and the first type measurement signal sent by the terminal device 105 may be used for the network device 104 to perform measurement. Alternatively, the first type of measurement signal may be a dedicated measurement signal as described above.

Second type measurement signal: the second type of measurement signal may be understood as another type of measurement signal. Alternatively, the second type measurement signal may be used for measurement by a device other than the network device of the local cell. Still taking the communication scenario 100 as an example, the second type of measurement signal sent by the terminal device 102 may be used for at least one of the terminal device 103, the network device 104, and the terminal device 105 to perform measurement, and the second type of measurement signal sent by the terminal device 105 may be used for at least one of the terminal device 102, the terminal device 103, and the network device 101 to perform measurement. Alternatively, the second type of measurement signal may be the common measurement signal above.

The method of the embodiment of the present application is described in detail below with reference to fig. 2 to 6.

FIG. 2 is a schematic interaction diagram of an example of a method according to an embodiment of the present application. It should be understood that fig. 2 shows detailed steps or operations of the method 200, but these steps or operations are merely examples, and other operations may also be performed or only some of the operations of fig. 2 may be performed by embodiments of the present application. The first network device in fig. 2 may be the network device 101 in the communication scenario 100, the first terminal device may be the terminal device 102 in the communication scenario 100, the second terminal device may be the terminal device 103 or the terminal device 105 in the communication scenario 100, and the second network device may be the network device 104 in the communication scenario 100. It should be understood that the first terminal device may also be the terminal device 103 or other terminal devices in the communication scenario 100.

As shown in fig. 2, the method 200 may include 210 and 220.

210. The first network device determines first configuration information and second configuration information.

The first network device may be a network device serving the first terminal device. The first configuration information is used for configuring a first resource for the first terminal device to send a first type measurement signal. The second configuration information is used for configuring a second resource for the first terminal device to send a second type measurement signal.

It should be understood that, unless otherwise specified, the first type measurement signal and the second type measurement signal are both measurement signals of the first terminal device.

Alternatively, the first type of measurement signal may be used for measurements by the first network device. The first network device may be a network device serving the first terminal device. The second type of measurement signal may be used for measurements by at least one of a second network device and a second terminal device. The second network device is a different network device than the first network device. Alternatively, the second network device may be a network device adjacent to the first network device.

Optionally, the first type of measurement signal and the second type of measurement signal are different measurement signals.

For example, the sequence of the first type of measurement signal is a first sequence, the sequence of the second type of measurement signal is a second sequence, and the first sequence and the second sequence are different. Alternatively, the first sequence may be a dedicated sequence for the first terminal device, and the second sequence may be a common sequence for a plurality of terminal devices, including the first terminal device. That is, the first type measurement signal may be a measurement signal dedicated to the first terminal device, and the second type measurement signal may be a measurement signal common to a plurality of terminal devices including the first terminal device.

Further optionally, the first sequence may be generated based on an identification number (ID) of the first terminal device, the second sequence may be generated based on an ID of the first network device, or the second sequence may be generated based on an ID of a user group to which the first terminal device belongs.

For another example, the scrambling code used by the first terminal device to transmit the first type of measurement signal may be a first scrambling code, and the scrambling code used by the first terminal device to transmit the second type of measurement signal may be a second scrambling code, where the first scrambling code and the second scrambling code are different. Alternatively, the first scrambling code may be a dedicated scrambling code for the first terminal device, and the second scrambling code may be a common scrambling code for a plurality of terminal devices, including the first terminal device.

Further optionally, the first scrambling code may be generated based on an ID of the first terminal device, the second sequence may be generated based on an ID of the first network device, or the second scrambling code may be generated based on an ID of a user group to which the first terminal device belongs. The description of the correlation between the first scrambling code and the second scrambling code may refer to the above description of the correlation between the first sequence and the second sequence, which is not repeated herein for brevity.

For another example, the cyclic shift used by the first terminal device to transmit the first type of measurement signal may be a first cyclic shift, and the cyclic shift used by the first terminal device to transmit the second type of measurement signal may be a second cyclic shift, where the first cyclic shift and the second cyclic shift are different. Alternatively, the first cyclic shift may be a dedicated cyclic shift of the first terminal device, and the second cyclic shift may be a cyclic shift common to a plurality of terminal devices, wherein the plurality of terminal devices includes the first terminal device.

Further optionally, the first cyclic shift may be generated based on an ID of the first terminal device, the second sequence may be generated based on an ID of the first network device, or the second cyclic shift may be generated based on an ID of a user group to which the first terminal device belongs. The description of the first cyclic shift and the second cyclic shift can refer to the above description of the first sequence and the second sequence, which is not repeated herein for brevity.

As an optional example, the first resource may include at least one of the following:

1) time domain resources

That is, the first configuration information may be used to configure time domain resources for the first terminal device to transmit the first type measurement signal.

Wherein, the time domain resource configured by the first configuration information may include at least one time domain position. That is, the first resource may include at least one time domain location.

For example, the first configuration information may be used to indicate a starting time domain position, an interval duration, and a repetition number. Suppose the starting time domain position is symbol # F of time slot # S, the interval duration is T (T ≧ 0) time slots, and the repetition number is M (M ≧ 2). The first resource may include M time domain positions (M symbols), a starting position of the M time domain positions is a symbol # F of a slot # S, and a distance between two adjacent time domain positions of the M time domain positions is T slots.

It should be understood that symbol # F of slot # S can be understood as: symbol numbered F in the slot numbered S. For example, suppose S is 1 and F is 6, and symbol # F of slot # S is specifically the symbol numbered 6 in slot number 1.

It should also be understood that in the embodiments of the present application, the interval between two time units is the difference between the numbers corresponding to the two time units. For example, T slots are provided between symbol # F of slot # S and symbol # F of slot # (S + T).

As another example, the first configuration information may be used to indicate a time domain location.

2) Frequency domain resources

That is, the first configuration information may be used to configure frequency domain resources for the first terminal device to transmit the first type measurement signal.

Wherein the frequency domain resource configured by the first configuration information may include at least one frequency domain position. That is, the first resource may include at least one frequency domain location.

For example, the first resource may include a first frequency band. The first frequency band can be used for the first terminal device to transmit a first type of measurement signal.

3) Time period

That is, the first configuration information may be used to configure a time period for the first terminal device to transmit the first type measurement signal.

For example, the first configuration information may be used to indicate a time domain location and time period. Assuming that the time domain position is the symbol # F of the slot # S and the time period is T slots, the first resource may include the symbol # F of the slot # S, the symbol # F of the slot # (S + T), and the symbol # F … of the slot # (S + 2T).

It should be understood that if the first resource includes a time period, the first resource may be considered to include a plurality of time domain locations.

4) Cyclic shift

That is, the first configuration information may be used to configure a cyclic shift for the first terminal device to transmit the first type of measurement signal.

5) Sequence of measurement signals of a first type

That is, the first configuration information may configure the first terminal device with a sequence of the first type of measurement signal. For example, the first configuration information may include a first sequence.

6) Scrambling code

That is, the first configuration information may configure a scrambling code for the first terminal device to transmit the first type measurement signal. For example, the first configuration information may include a first scrambling code.

The description of the second configuration information may refer to the above description of the first configuration information, and is not repeated herein for brevity.

220. The first network equipment sends first configuration information and second configuration information to the first terminal equipment; accordingly, the first terminal device receives the first configuration information and the second configuration information from the first network device.

It should be understood that the first configuration information and the second configuration information may be carried in different signaling (messages) or may be carried in the same signaling (message).

Taking the first configuration information as an example, the first configuration information may be carried in the higher layer signaling or the physical layer signaling. For example, the first configuration information may be carried in Radio Resource Control (RRC) signaling or Medium Access Control (MAC) Control Element (CE) signaling. Higher layer signaling (e.g., RRC signaling) is semi-statically varied, which is beneficial to reduce signaling overhead.

230. The first terminal equipment sends the first type measurement signal according to the first resource; the first terminal equipment sends the second type measurement signal according to the second resource; accordingly, the first network device may measure the first type of measurement signal on the first resource, and at least one of the second network device and the second terminal device may measure the second type of measurement signal on the second resource.

Optionally, to facilitate interference measurement and coordination, at least one of a time domain resource location, a frequency domain resource location, a sequence, a scrambling code, and a cyclic shift of the second type measurement signal may be negotiated in advance between the first network device and the second network device (which is equivalent to the second network device determining the second resource), so that at least one of the second network device and a terminal device covered by the second network device may perform measurement on the second type measurement signal according to the second resource.

It should be understood that, if the second terminal device is the terminal device covered by the first network device, the second terminal device may determine the second resource through the first network device, and if the second terminal device is the terminal device covered by the second network device, the second terminal device may determine the second resource through the second network device.

In this embodiment of the present application, a first network device respectively configures resources for a first terminal device to send two types of measurement signals, where the first terminal device may send a first type of measurement signal according to a first resource, and send a second type of measurement signal according to a second resource, so that the first network device may measure the first type of measurement signal on the first resource, and at least one of a second network device and a second terminal device may measure the second type of measurement signal on the second resource, thereby being beneficial to meeting requirements of different devices for measuring the measurement signal of the first terminal device.

Further, the first type measurement signal may be a measurement signal dedicated to the first terminal device, which is beneficial for the first network device to identify the received measurement signal (i.e., identify the first type measurement signal), and is beneficial for the first network device to perform measurement efficiently. The second type of measurement signal may be a measurement signal common to a plurality of terminal devices, facilitating identification of the received measurement signal (i.e. identification of the second type of measurement signal) by at least one of the second network device and the second terminal device. The scheme is beneficial to reducing the complexity of the equipment for identifying the measurement signal.

In the above, it is described that the first network device may configure corresponding resources for the two types of measurement signals of the first terminal device, respectively. The following describes in detail how the first terminal device transmits the two types of measurement signals.

Mode #1

The 230 may include:

the first terminal equipment sends a first type of measurement signal according to the configuration of the first configuration information;

and the first terminal equipment sends the second type measurement signal according to the configuration of the second configuration information.

In the following, the first terminal device sends the first type measurement signal as an example, and it should be understood that the manner in which the first terminal device sends the second type measurement signal may refer to the manner in which the first terminal device sends the first type measurement signal.

Assuming that the first resource indicated by the first configuration information corresponds to at least one time domain position, the first terminal device may transmit a first type measurement signal at each of the at least one time domain position. Optionally, the first network device may receive a first type of measurement signal at each of the at least one time domain locations.

It is assumed that the first resource indicated by the first configuration information corresponds to one time domain position and a time period (i.e., the first resource includes a plurality of time domain positions having periodicity). The first terminal device may periodically transmit a first type measurement signal according to the time domain location and the time period. Optionally, the first network device may periodically receive the first type of measurement signal.

It is assumed that the first resources comprise time-frequency resources and the second resources comprise time-frequency resources. The first resource may comprise time-frequency resources having overlapping portions with the time-frequency resources comprised by the second resource. The overlapping part of the time-frequency resource included in the first resource and the time-frequency resource included in the second resource can be understood as follows: the first resource and the second resource comprise the same time-frequency resource.

For example, assume that the first resource includes resource # R, the time domain resource of which is symbol # F of slot # S, the frequency domain resource of which is the first frequency domain resource, and the second resource also includes resource # R. That is, the overlapping portion includes resource # R.

In this case, the first terminal device may transmit the first type measurement signal or the second type measurement signal at the overlapping portion based on at least one of the following manners.

1) Based on priority

In particular, the first network device may pre-configure the priority of the first type of measurement signal and the second type of measurement signal. If the time-frequency resources used for transmitting the first type of measurement signal and the time-frequency resources used for transmitting the second type of measurement signal have an overlapping portion, the measurement signal with higher priority may be transmitted in the overlapping portion according to priority.

For example, it is assumed that the first type of measurement signal has a higher priority than the second type of measurement signal. The first resource includes resource # R and the second resource includes resource # R. The first terminal device may transmit the first type measurement signal on the resource # R according to the priority.

2) Based on the indication information

Specifically, the method may further include:

201. the method comprises the steps that a first network device sends indication information to a first terminal device, wherein the indication information is used for indicating a first type of measurement signal or a second type of measurement signal; the first terminal equipment transmits the measurement signal indicated by the indication information in the overlapping part.

For convenience of explanation, the "indication information for indicating the first type measurement signal or the second type measurement signal" may be written as "first indication information"

For example, the first resource includes resource # R, the second resource includes resource # R, and the resource # R is an overlapping portion. The first terminal device receives first indication information. The first indication information is used for indicating a first type of measurement signal, and the first terminal device transmits the first type of measurement signal on the resource # R according to the first indication information.

Alternatively, the first terminal device may receive the first indication information on a time unit in which the overlapping portion (e.g., resource # R) is located.

It should be understood that the resource # R is assumed to be the symbol # F of the slot # S, and the time unit in which the resource # R is located is the slot # S. Assuming that the first terminal device receives the first indication information on the slot # S, the first terminal device transmits the measurement signal indicated by the first indication information on the resource # R.

Optionally, the first indication information may be carried in Downlink Control Information (DCI). Specifically, the first terminal device receives DCI in a first time unit, and transmits a measurement signal indicated by first indication information in the overlapping portion according to the first indication information carried in the DCI.

Optionally, the first indication information may be carried in Radio Resource Control (RRC) signaling. Specifically, the first terminal device may transmit the measurement signal indicated by the first indication information in each of the at least one overlapping section.

That is, in the mode #1, the first terminal device may transmit the first type measurement signal based on the configuration of the first configuration information, and the first terminal device may transmit the second type measurement signal based on the configuration of the second configuration information. Optionally, if the time-frequency resource included in the first resource configured by the first configuration information and the time-frequency resource included in the second resource configured by the second configuration information have an overlapping portion, the first terminal device may send a corresponding measurement signal in the overlapping portion according to the priority or the first indication information.

Mode #2

The first terminal equipment sends a first type measurement signal according to a first preset condition and a first resource;

and the first terminal equipment sends the second type measurement signal according to the second preset condition and the second resource.

Taking the example that the first terminal device transmits the second type of measurement signal, the second preset condition may include at least one of the following two conditions. It should be understood that the relevant description of the first preset condition can refer to the relevant description of the second preset condition.

1) And the first terminal equipment transmits data in an uplink mode.

That is, the first terminal device may determine whether to transmit the second type measurement signal at a time domain position included in the second resource according to whether the first terminal device subsequently transmits data (uplink).

If the first terminal device determines that the first terminal device transmits data uplink subsequently, before the first terminal device transmits data uplink, the first terminal device may transmit the second type measurement signal at a time domain position included in the first resource.

On the contrary, if the first terminal device determines that the first terminal device does not perform uplink transmission subsequently, the first terminal device may not transmit the second type measurement signal at the time domain position included in the first resource.

Specifically, the second resource may include a first time unit, or the second resource includes a first symbol, the first symbol belongs to the first time unit, and the first terminal device may determine whether to transmit the second type measurement signal on the first time unit, or determine whether to transmit the second type measurement signal on the first symbol of the first time unit, according to whether a second time unit after the first time unit is used for uplink data transmission of the first terminal device.

It should be understood that, as can be seen from the above, the time unit may be a time unit for scheduling a transport block, and the second resource including the first time unit may be understood as: the second resource includes a partial time domain resource in the first time unit.

For example, assume that the second configuration information is used to indicate a time domain location and a time period. The time domain position is symbol # F of slot # S, the time period is T slots, and the second resource may include a plurality of time units such as slot # S, slot # (S + T), slot # (S +2T), and the like. The first resource specifically includes a plurality of time domain positions, such as a slot # S symbol # F, a slot # (S + T) symbol # F, and a slot # (S +2T) symbol # F.

The 230 may include:

and if a second time unit after the first time unit is used for the first terminal equipment to transmit data in an uplink mode, the first terminal equipment transmits the second type measurement signal in the first time unit. Optionally, if the second time unit is configured by the first network device for non-uplink transmission, or the second time unit is configured by the first network device for uplink transmission but is not used for uplink data transmission by the first terminal device (i.e. the first terminal device does not transmit data uplink in the second time unit), the first terminal device does not transmit the second type measurement signal in the first time unit.

Further optionally, the second time unit and the first time unit may be separated by k time units (or the separation between the second time unit and the first time unit is less than or equal to k time units). The value k may be pre-agreed for the first network device and the first terminal device, or may be configured by the first network device for the first terminal device, which is not limited in this embodiment of the present application.

As an alternative example, k time units may be separated from the first time unit, and if the value of k is equal to N (N ≧ 1), whether the first terminal device transmits the second type measurement signal in the first time unit depends on whether the nth time unit (i.e., the second time unit) after the first time unit is used for the first terminal device to transmit data uplink. And if the Nth time unit after the first time unit is used for the first terminal equipment to transmit data in an uplink mode, the first terminal equipment transmits the second type measurement signal in the first time unit. On the contrary, if the nth time unit after the first time unit is not used for the first terminal device to transmit data uplink, the first terminal device does not transmit the second type measurement signal in the first time unit.

As another alternative, the interval between the second time unit and the first time unit is less than or equal to k time units, and if the value of k is equal to N (N ≧ 1), whether the first terminal device transmits the second type measurement signal in the first time unit depends on whether a time unit in N time units (i.e., the second time unit) after the first time unit is used for the first terminal device to transmit data upstream. And if any time unit in the N time units after the first time unit is used for the first terminal equipment to transmit data in an uplink mode, the first terminal equipment transmits the second type measurement signal in the first time unit. On the contrary, if any time unit of the N time units after the first time unit is not used for the first terminal device to transmit data in the uplink, the first terminal device does not transmit the second type measurement signal in the first time unit.

Fig. 3 is a schematic diagram of an example of a communication method according to an embodiment of the present application. As shown in fig. 3, assuming that the k value is 1, the first terminal device determines that the second time unit is used for the first terminal device to uplink transmit data, and the first terminal device may determine that the second type measurement signal is uplink transmitted in the first time unit.

As an alternative example, at least one of the second terminal device and the second network device may determine whether to measure the second type of measurement signal in the first time unit according to whether data is received in the second time unit. For example, if a second network device receives data over a second time unit, the second network device may receive a second type of measurement signal over the first time unit. For another example, assuming that the second terminal device determines to receive data downstream in the second time unit, the second terminal device may measure the second type measurement signal in the first time unit. The second terminal device may report the measurement result, so that the network device serving the second terminal device may schedule the second terminal device to receive data in a downlink manner in the second time unit according to the measurement result, which is beneficial to improving the success rate of receiving data in the downlink manner by the second terminal device.

As another alternative, the second network device may determine whether to measure the second type measurement signal in the first time unit according to whether the second time unit is used for the second network device to send data in a downlink. For example, if the second network device sends data downstream in the second time unit, the second network device may measure the second type measurement signal in the first time unit. Further, the second network device may schedule downlink transmission of the second time unit according to the measurement result.

Fig. 4 is a schematic diagram of another example of a communication method according to an embodiment of the present application. As shown in fig. 4, the second network device determines to send data downlink in the second time unit, and the second network device may measure the second type measurement signal in the first time unit, and determine the scheduling information of downlink transmission in the second time unit according to the measurement result, and indicate the scheduling information to the terminal device in the local cell through DCI.

For example, the second network device may estimate the area or orientation in which the first terminal device that transmitted the second type of measurement signal is located by scanning to AOA estimation or by wavenumber group. The second network device may also determine the cell where the first terminal device is located according to scrambling code information or sequence information carried by the second type measurement signal.

The second network device may determine the interference level of the first terminal device with the terminal device of the cell by measuring the second type measurement signal. The second network device may perform interference coordination on terminal devices of the local cell (e.g., terminal devices covered by the second network device and close to the first terminal device) according to the interference degree and the location of the first terminal device.

Optionally, the first network device sends at least one of different parameters of a code domain, a frequency domain, and a cyclic shift of the second type measurement signal to different terminal devices, so that at least one of the second network device and the second terminal device can distinguish different terminal devices in the first network device according to a code division, a frequency division, or a cyclic shift.

For example, the frequency domain resource of the first network device includes a plurality of BPs, each BP may be used to schedule m (m ≧ 1) terminal devices, and within one BP, the m terminal devices may perform resource multiplexing using code division, frequency division, or cyclic shift, etc.

Fig. 5 is a diagram illustrating another example of a communication method according to an embodiment of the present application. As shown in fig. 5, each BP in the multiple BPs may be used to schedule multiple terminal devices, and frequency domain resources of the second type measurement signal corresponding to different terminal devices in the same BP are different (i.e., frequency division), or code domain resources corresponding to different terminal devices are different (i.e., code division), so that at least one of the second network device and the second terminal device may determine the second type measurement signal sent by each terminal device in the multiple terminal devices according to the frequency division or the code division.

Optionally, the 230 may include:

the first terminal equipment sends the second type of measurement signal on a first time-frequency resource, wherein the time-frequency resource of the first time-frequency resource belongs to a first time unit and the frequency-frequency resource is a first frequency-frequency resource, the second time-frequency resource is used for the first terminal equipment to send data, and the time-frequency resource of the second time-frequency resource belongs to a second time unit and the frequency-frequency resource is a second frequency-frequency resource. The first frequency domain resources may be a full set or a subset of the second frequency domain resources.

For example, assuming that the first resource includes symbol # F of a first time unit, the first terminal device will transmit data on frequency domain resource # a of a second time unit, and the first terminal device may transmit the second type measurement signal on resource # Z, where the time domain resource of resource # Z is symbol # F of the first time unit and the frequency domain resource of resource # Z is frequency domain resource # a.

That is, the frequency domain resources used by the first terminal device to transmit the second type of measurement signal on the first time unit may be determined according to the frequency domain resources used by the first terminal device to transmit data on the second time unit, or the frequency domain resources used by the first terminal device to transmit the second type of measurement signal on the first time unit may be the full set or a subset of the frequency domain resources used by the first terminal device to transmit data on the second time unit.

Fig. 6 is a schematic diagram of still another example of a communication method according to an embodiment of the present application. As shown in fig. 6, the first terminal device may transmit the second type measurement signal on the first time unit using the frequency domain resource for uplink data transmission of the first terminal device.

Optionally, the first terminal device may determine whether the first terminal device transmits data uplink in multiple ways.

For example, the method 200 may further include:

202. the first network device sends scheduling information to the first terminal device, where the scheduling information is used to allocate a second time unit (or allocate time domain resources, where the allocated time domain resources are part of time domain resources in the second time unit) to the first terminal device for uplink data sending; accordingly, the first terminal device receives the scheduling information before the first terminal device transmits the second type of measurement signal over the first time unit.

The first terminal device may determine to transmit the second type of measurement signal on the first time unit according to the scheduling information.

Further, the scheduling information may also be configured to allocate a second frequency domain resource to the first terminal device for uplink data transmission, where the first terminal device may transmit the second type measurement signal on the first time-frequency resource in which the time domain is the first time unit and the frequency domain is the first frequency domain resource, and the first frequency domain resource is a full set or a subset of the second frequency domain resource.

For another example, if the second terminal device has a need to transmit data over a second time unit, the second terminal device may transmit a second type of measurement signal over the first time unit.

2) The first terminal device receives indication information for indicating the first terminal device to send the second type measurement signal.

For convenience of explanation, the indication information for instructing the first terminal device to transmit the second type measurement signal may be referred to as "second indication information".

That is, the first terminal device may determine whether to transmit the second type measurement signal on the resource included in the second resource according to whether the second indication information is received.

If the first terminal device receives the second indication information, the first terminal device may send the second type measurement signal on a resource included in the second resource.

That is, the first network device configures a second resource for the first terminal device, the second resource includes at least one time domain location, and the first terminal device needs to transmit the second type measurement signal on the corresponding resource based on the second indication information.

For example, assume that the second configuration information is used to indicate a time domain location and a time period. The time domain position is a symbol # F of a slot # S, the time period is T slots, and the first resource may include a plurality of time domain positions such as a symbol # F of a slot # S, a symbol # F of a slot # (S + T), a symbol # F of a slot # (S +2T), and the like.

If the first terminal device receives the second indication information at the time slot # S or at the time slot located before the time slot # S, the first terminal device may transmit the second type measurement signal at the time slot # S according to the second indication information.

On the contrary, if the first terminal device does not receive the second indication information in the time slot # S or the time slot before the time slot # S, the first terminal device does not transmit the second type measurement signal in the time slot # S.

Here, after the first terminal device acquires the second configuration information, it needs to transmit the second type measurement signal on the corresponding resource according to the indication of the second indication information. In other words, the second indication information corresponds to trigger information for triggering the first terminal device to transmit the second type measurement signal on the corresponding resource.

It should be understood that, for the way in which the first terminal device sends the first type of measurement signal, reference may be made to the way in which the first terminal device sends the second type of measurement signal, and for brevity, the description is omitted here.

It is described above that the first configuration information may configure the first resource for the first terminal device to transmit the first type measurement signal, and the second configuration information may configure the second resource for the first terminal device to transmit the second type measurement signal. In an actual communication process, a situation may occur in which a resource configured by the configuration information conflicts with a transmission direction configured for the resource by the first network device.

For example, assume that the second resource includes a first symbol, that is, the first symbol is used for uplink transmission. Since the transmission direction of the time unit in the system can be flexibly changed, the first symbol may be configured as non-uplink transmission by the first network device, that is, the first symbol is used for non-uplink transmission by the first network device, and at this time, the transmission direction of the first symbol collides.

For convenience of description, the "transmission direction of the time domain position (e.g., symbol) corresponding to the configuration information collides with the transmission direction configured for the time domain position by the first network device" may be denoted as "the transmission direction of the time domain position collides".

Fig. 7 is a schematic diagram illustrating an example of collision of transmission directions according to an embodiment of the present application. As shown in fig. 7, it is assumed that the second resource includes a symbol # a of a time cell # a, a symbol # B of a time cell # B, a symbol # C of a time cell # C, and a symbol # D of a time cell # D. Since the transmission direction of the time unit in the system can be flexibly changed, the time unit # a and the time unit # B are configured by the first network device for downlink transmission, the symbol # C of the time unit # C is configured as unknown, and the time unit # D is configured by the first network device for uplink transmission.

At this time, the transmission directions of the symbol # a, the symbol # B, and the symbol # C collide.

For the second type measurement signal, if the transmission direction of the time unit included in the second resource conflicts and the transmission of the second type measurement signal is interrupted, since the second network device or the second terminal device cannot acquire the situation in time, the measurement result is incorrect due to the fact that the second network device or the second terminal device continues to perform measurement, and then the related coordination process and the system performance are affected. Therefore, when a collision occurs, the second terminal device preferably continues to transmit the second type measurement signal at the time domain position (e.g., symbol # a) where the collision occurred. Optionally, the first network device needs to schedule resources as much as possible so as not to interfere with the first terminal device to transmit the second type measurement signal in the time unit where the collision occurs. For example, the first network device does not transmit downstream on this symbol # a.

That is, the second resource comprises a first time domain position (or first symbol), on which the first terminal device (still) transmits the second type measurement signal if the first time domain position is configured by the first network device for non-uplink transmission.

For the first type measurement signal, if the transmission directions of the time units included in the first resource collide, the first terminal device may stop transmitting the first type measurement signal on the time units where the collision occurs.

For example, the first resource may include a symbol # e, and the first terminal device may stop transmitting the first type measurement signal on the symbol # e if the symbol # e is configured by the first network device for non-uplink transmission.

Alternatively, the first terminal device may determine the transmission direction configured for the time unit by the first network device in various ways. For example, the method 200 may include:

203. the first network equipment sends transmission direction information; accordingly, the first terminal device may receive the transmission direction information from the first network device. Wherein the transmission direction information may be used to indicate a transmission direction of each of at least one symbol, the plurality of symbols including the first symbol. Or the transmission direction information may be used to indicate the transmission direction of each symbol in a time unit. For example, assuming that the time unit is a slot, the transmission direction information may be Slot Format Information (SFI). Optionally, each time unit may include transmission direction information for indicating a transmission direction of each symbol in the time unit.

The first terminal device may determine whether the transmission directions of the time domain locations included in the resource configured by the configuration information conflict according to the transmission direction information.

Similarly, the transmission direction of the time unit of the cell to which the receiving end of the measurement signal belongs may also be flexibly changed. In this case, the receiving end of the measurement signal may abandon the measurement or continue the measurement. For example, assuming that the second terminal device is a terminal device under the coverage of the second network device, the second network device sends third configuration information to the second terminal device, where the third configuration information is used to configure a third resource for the second terminal device to receive the measurement signal, and the third resource includes a first symbol, that is, in the third configuration information, the first symbol is used for downlink transmission. Since the transmission direction of the time unit can be flexibly configured, the first symbol may be configured as non-downlink transmission by the second network device, and in this case, the second terminal device may measure the received measurement signal on the first symbol, or may abandon the measurement.

Optionally, in this embodiment of the present application, the first terminal device may send the first type measurement signal and the second type measurement signal using the same or different uplink timing (timing).

In the above, it is described that the first terminal device may transmit the first type measurement signal and the second type measurement signal according to the two configuration information, respectively. Wherein the second type of measurement signal may be used for at least one of the second network device and the second terminal device to perform measurements. Another example of the communication method according to the embodiment of the present application is described below. The method is beneficial to improving the accuracy of the second type measurement signal measured by the second terminal equipment.

Fig. 8 is a schematic interaction diagram of another example of a communication method according to an embodiment of the present application. It should be understood that fig. 8 shows detailed steps or operations of the method 300, but these steps or operations are merely examples, and other operations may also be performed or only some of the operations of fig. 8 may be performed by embodiments of the present application.

310. The network device determines a third resource, which belongs to a resource for the terminal device to transmit the measurement signal.

It should be understood that the terminal device does not refer to a fixed terminal device, but rather broadly refers to a terminal device in the system. The resource for the terminal device to transmit the measurement signal is understood as: and the resource is used for the terminal equipment in the system to send the measurement signal. The resource for the terminal device to transmit the measurement signal may be understood as a measurement signal resource pool. The network device may select a resource from the resource pool and allocate the selected resource to a certain terminal device, for example, allocate the selected resource to terminal device # a, which may transmit a measurement signal according to the allocated resource.

For example, the resource for the terminal device to transmit the measurement signal uplink may be a resource indicated by an uplink measurement resource configuration table. For example, the resource indicated by the SRS configuration table (the uplink measurement resource configuration table will be described in detail later).

Optionally, the third resource may comprise the full set or subset of the second resource above.

Optionally, the third resource includes a time-frequency resource. That is, the time-frequency resource included in the third resource belongs to the time-frequency resource used for the terminal device to transmit the measurement signal.

320. The network equipment sends third configuration information to the second terminal equipment; accordingly, the second terminal device receives the third configuration information from the network device.

Wherein the third configuration information is used for configuring a third resource for the second terminal device to receive the measurement signal. The third resource belongs to a resource for the second terminal device to perform the relevant measurement.

330. And the second terminal equipment measures the received measuring signal on the third resource.

Alternatively, the measurement signal received by the second terminal device may be from the first terminal device.

That is, in the embodiment of the present application, the second terminal device may receive the measurement signal according to the resource for transmitting the measurement signal. The method is beneficial to realizing the time frequency resource alignment of the sending end of the measuring signal and the receiving end of the measuring signal.

This is because, in the related art, the resource used by the terminal device to receive the measurement signal is different from the resource used by the terminal device to transmit the measurement signal. For example, the terminal device receives the measurement signal using a channel state information reference signal (CSI-RS) resource. The CSI-RS resource corresponds to one or more CSI-RS resource element structures (component CSI-RS RE patterns). For ease of illustration, the "CSI-RS resource element structure" may be denoted as a "CSI-RS structure" which may be denoted as (Y, Z). Where Y represents the number of consecutive resource units in the frequency domain and Z represents the number of consecutive resource units in the time domain. For example, (Y, Z) may have various structures such as (2, 1), (4, 1), (8, 1) (2, 2), and (2, 4). In the prior art, the terminal device transmits the SRS resource used by the measurement signal. The SRS resources are distributed in a comb-tooth shape in a frequency domain, and the interval between two adjacent subcarriers on each comb-tooth-shaped SRS resource is L. Alternatively, L may be equal to 2 or 4. It can be seen that the structures of the CSI-RS resources and the SRS resources are mismatched. Therefore, if the first terminal device sends the SRS, the second terminal device measures the SRS sent by the first terminal device according to the CSI-RS resource, which may result in inaccurate measurement result.

For example, the first terminal device transmits a measurement signal in a first resource, where the time domain resource of the first resource is symbol #1, the frequency domain resource is odd-numbered subcarriers (1,3,5, 7.) and the second terminal device performs measurement on a plurality of continuous subcarriers in symbol #1 based on the limit value of the CSI-RS resource, which results in inaccurate measurement of the second terminal device.

Therefore, in this embodiment of the present application, the third resource configured by the network device for the second terminal device belongs to a resource used for the terminal device to send the measurement signal, which is beneficial to achieving alignment between the sending end of the measurement signal and the receiving end of the measurement signal, and is beneficial to improving the measurement accuracy.

In the prior art, a terminal device may store a downlink measurement resource configuration table (e.g., CSI-RS configuration table) and an uplink measurement resource configuration table (e.g., SRS configuration table).

And the terminal equipment acquires the specific time frequency resource position of the downlink measurement reference signal according to the parameter and a downlink measurement resource configuration table. Specifically, the downlink measurement signal resource configuration table may include:

resourceConfig INTEGER(0..31)

subframeConfig INTEGER(0..154)

…

the value range of the parameter resourceConfig is 0 to 31, and the parameter can be used for determining Resource Elements (REs) and symbol positions of the CSI-RS reference signal in one subframe. The subframe config has a value ranging from 0 to 154, and can be used to determine the subframe position of the CSI-RS reference signal.

The downlink measurement resource parameter may be used to indicate a value of a parameter resourceConfig and a value of a parameter subframeConfig.

And the terminal equipment acquires the specific time frequency resource position of the uplink measurement reference signal according to the uplink measurement resource parameter and an uplink measurement resource configuration table. Specifically, the uplink measurement resource configuration table may include:

srs-ConfigIndex INTEGER(0..1023)

…

the parameter SRS-ConfigIndex has a value range of 0-1023, and can be used to determine an SRS transmission period and a time domain (e.g., a subframe position). The uplink measurement resource parameter may be used to indicate the value of the parameter srs-ConfigIndex.

As an optional example, the resource for the terminal device to send the measurement signal may include a resource corresponding to all values of the parameter srs-ConfigIndex from 0 to 1023. The third configuration information may be used to indicate a specific value of the parameter srs-ConfigIndex (it should be understood that the specific value indicated by the third configuration information belongs to 0-1023), and a resource corresponding to the value indicated by the third configuration information is the third resource. The second terminal device may determine the third resource according to a value of the parameter srs-ConfigIndex indicated by the third configuration information.

The uplink and downlink measurement resource parameters in the existing configuration are configured through different messages, and the terminal equipment obtains configuration parameters such as time-frequency resources of downlink measurement reference signals according to the downlink configuration resource parameters and a downlink resource configuration table. And the terminal obtains configuration parameters such as time-frequency resources and the like of the uplink measurement reference signal according to the uplink configuration resource parameters and the uplink resource configuration table.

If the network device configures a second terminal to measure a measurement signal sent by the first terminal, the measurement signal resource configuration configured by the network device for the second terminal at least needs to include an uplink measurement signal resource configuration configured by the first terminal device.

As an optional example of the present application, the second terminal device may store an extended downlink measurement resource configuration table, and copy a relevant parameter corresponding to the uplink measurement resource configuration to a downlink measurement signal resource table set. The corresponding parameters in the extended CSI-RS configuration table may be as follows:

resourceConfig_r15 INTEGER(0..xx)

subframeConfig_r15 INTEGER(0..yy)

…

the value of the parameter resourceConfig _ r15 ranges from 0 to xx, and the parameter includes the resource configuration for measuring the measurement signal transmitted from the network device and the resource configuration for measuring the measurement signal transmitted from the other terminal device. The parameter subframe config _ r15, which can be used to determine the subframe location where the resource configuration of the measurement signal sent from the network device is located, has a value ranging from 0 to yy. The third resource may be specifically configured to indicate a value of a parameter resourceConfig _ r15 and a value of a parameter subframeConfig _ r 15. The second terminal device may measure the sounding reference signal sent by the first terminal according to the third resource and the extended downlink sounding resource configuration table.

As another alternative example of the present application, the second terminal device may store a measurement resource configuration table for measuring measurement signals of the local cell network device and a measurement resource configuration table for measuring measurement signals of other terminal devices, respectively.

And the network equipment indicates the first terminal equipment to carry out corresponding measurement by configuring the measurement resource parameter.

The configuration table may be as follows:

resourceConfig_r15 INTEGER(0..31)

subframeConfig_r15 INTEGER(0..154)

srs-ConfigIndex_r15 INTEGER(0..1023)

…

the second terminal determines the resources for measuring the measurement signals transmitted by the network equipment according to the parameter resourceConfig _ r15 and the parameter subframeConfig _ r15, and determines the resources for measuring the measurement signals transmitted by other terminal equipment through the parameter srs-configIndex _ r 15.

Optionally, the third resource includes a first time unit, and the second terminal device measures the received measurement signal on the third resource, including:

and if a second time unit after the first time unit is used for the second terminal equipment to receive data, the second terminal equipment measures the received measurement signal in the first time unit.

Specifically, the relevant description of this step can refer to the relevant description of the method 200 above, and is not repeated for brevity.

Alternatively, the second terminal device may determine whether the second time unit is used for the second terminal device to receive data in a variety of ways.

For example, the method 300 may optionally include:

301. and the network equipment sends scheduling information to the second terminal equipment, wherein the scheduling information is used for allocating a second time unit for the second terminal equipment to receive data, and the scheduling information is also used for the second terminal equipment to determine that the second type of measurement signal is sent on the first time unit.

Alternatively, the network device in the method 300 may be the first network device or the second network device described above. The second terminal device in the method 200 may be the second terminal device in the method 200.

It should be understood that the specific description of the method 300 can be found in relation to the description of the method 200 above, and is not repeated here for brevity.
