Detailed ways

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

It should be understood that the manners, the conditions, the categories, and the divisions of the embodiments in the embodiments of the present application are only for convenience of description, and should not be specifically limited. The various modes, categories, situations, and features in the embodiments are not contradictory. In case you can combine them.

It should also be understood that the terms "first", "second", and "third" in the application examples are merely a distinction and should not be construed as limiting.

It should also be understood that, in various embodiments of the present application, the size of the sequence number of each process does not mean the order of execution, and the order of execution of each process should be determined by its function and internal logic, and should not be taken to the embodiment of the present application. The implementation process constitutes any limitation.

It should also be understood that the technical solution of the present application can be applied to various communication systems, for example, a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, and a wideband code division. Wideband code division multiple access (WCDMA) system, general packet radio service (GPRS), long term evolution (LTE) system, advanced long-term evolution (LTE-Advanced) System, universal mobile telecommunication system (UMTS), next generation communication system (for example, fifth generation communication (5G) system), converged system of multiple access systems, or evolution system. Among them, the 5G system can also be called a new radio access technology (NR) system.

In the embodiment of the present application, the network device is a device deployed in the radio access network to provide a wireless communication function for the terminal device. The network device may include various forms of base stations, macro base stations, micro base stations (also referred to as small stations), relay stations, access points, new radio controllers (NR controllers), centralized network units (centralized units). The radio remote module, the distributed network unit, the transmission reception point (TRP) or the transmission point (TP), or any other wireless access device, but the embodiment of the present application is not limited thereto. . Among them, in systems using different wireless 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), or may be an evolved Node B (eNB or eNodeB) in the LTE system. Alternatively, the network device may also be a Node B of a 3rd generation (3G) system. In addition, the network device may also be a relay station or an access point, an in-vehicle device or a fifth-generation communication in the future (fifth- Generation, 5G) A network device in a network or a network device in a public land mobile network (PLMN) network that is evolving in the future.

In the embodiment of the present application, the terminal device may include various handheld devices having wireless communication functions, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to the wireless modem. The terminal device may be a device that accesses the network side through a network device (for example, NR or TRP) in a communication system (for example, 5G), and may also be called a user equipment (UE), which is a voice provided to the user. And/or data connectivity devices, for example, handheld devices with wireless connectivity, in-vehicle devices, and the like. Common terminals include, for example, mobile phones, tablets, notebook computers, PDAs, mobile internet devices (MIDs), wearable devices such as smart watches, smart bracelets, pedometers, and the like.

In a new generation of new radio access (NR) system, a UE-specific scheme is introduced for transmitting measurement signals. Optionally, the measurement signal may be a sounding reference signal (SRS).

That is to say, the terminal device can transmit the measurement signal specific to the terminal device, that is, the terminal device can transmit the measurement signal dedicated to the terminal device.

The measurement signals specific to the terminal device can also be referred to as "UE specific measurement signals". For convenience of explanation, a dedicated measurement signal can be referred to as a "dedicated measurement signal". Different measurement signals sent by different terminal devices are different. Wherein, the different measurement signals may include at least one of the following multiple situations:

Case #1: If the sequences of the two measurement signals are different, the two measurement signals can be considered different.

For example, assuming that the sequence of the dedicated measurement signals transmitted by the terminal device #A is the sequence #a, the sequence of the dedicated measurement signals transmitted by the terminal device #B is the sequence #b, and the sequence #a and the sequence #b are different sequences.

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

For example, suppose the scrambling code used by the terminal device #C to transmit the dedicated measurement signal is #c, and the scrambling code used by the terminal device #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 two measurement signals are different, it can be considered that the two measurement signals are different.

For example, suppose that the cyclic shift used by the terminal device #E to transmit the dedicated measurement signal is #e, and the cyclic shift used by the terminal device #F to transmit the dedicated measurement signal is #f, the cyclic shift is #e and the cyclic shift is # f is a different cyclic shift.

Similarly, the two measurement signals are the same and include multiple cases. For example, in case #1, if the sequences of the two measurement signals are the same, the two measurement signals can be considered to be the same. In case #2, if the two scrambling codes used to transmit the two measurement signals are the same, it can be considered that the two measurement signals are the same. In case #3, if the cyclic shifts used to transmit the two measurement signals are the same, it can be considered that the two measurement signals are the same.

Based on the above, the terminal device can transmit the dedicated measurement signal through at least one of a plurality of schemes.

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

As an alternative to another example, the terminal device may generate a dedicated measurement signal using a scrambling code (ie, a dedicated scrambling code) specific to the terminal device. In other words, the scrambling code used by the terminal device to transmit the dedicated measurement signal is a scrambling code specific to the terminal device. Different terminal devices use different measurement signals to transmit different measurement signals.

As an alternative, the terminal device can generate a dedicated measurement signal using a cyclic shift (ie, a dedicated cyclic shift) specific 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 specific to the terminal device.

The introduction of the dedicated measurement signal facilitates the network device serving the terminal device to efficiently identify the terminal device, and facilitates the network device to acquire some information related to the characteristics of the terminal device, thereby facilitating the network device to efficiently measure the measurement signal.

It should be understood that measuring the measurement signal by the receiving end (for example, the network device) of the measurement signal may include: the device determines the reference signal received power (RSRP) and the reference signal receiving quality by receiving the measurement signal (reference signal received) At least one of quality, RSRQ), channel quality indicator (CQI), channel state information (CSI), and received signal strength indicator (RSSI). Optionally, the measuring end of the measurement signal (for example, the network device) to measure the measurement signal may further include: estimating, by the device, an angle-of-arrival (AOA) estimation or a beam group scan to transmit the measurement signal. The area or orientation where the sender is located.

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

For example, in the communication system, assuming that the terminal device #A is transmitting signals on the uplink, in addition to the uplink reception signal of the network device #1 serving the terminal device #A, there may be other devices receiving signals. For example, terminal device #B is receiving a signal transmitted downstream of network device #2. The terminal device #B may receive the uplink signal sent by the terminal device #2 while receiving the signal sent by the downlink device #2, thereby causing the terminal device #A uplink transmission signal to interfere with the downlink reception signal of the terminal device #B, which is easy. The terminal device #B downlink receiving signal failed.

For this scenario, if the terminal device #A has strong interference to the terminal device #B, when the network device #2 learns that the terminal device #A transmits the uplink signal, the network device #2 may not schedule the downlink device #B to receive the signal, or The network device #2 can schedule the terminal device #B to receive a signal on a resource that does not overlap with the uplink transmission of the terminal device #A to avoid interference of the terminal device #A with the terminal device #B. That is to say, the network device #2 needs to obtain the interference information of the terminal device #A to the terminal device #B for scheduling the terminal device #B. This requires that the terminal device #B measures the measurement signal transmitted by the terminal device #A.

Similarly, the uplink transmission signal of the terminal device #A may also cause interference to the uplink reception of the network device #2, and the uplink transmission signal of the terminal device #A may also interfere with the downlink reception signals of other terminal devices of the local cell.

Therefore, not only the network device serving the terminal device needs to measure the measurement signal sent by the terminal device, but other devices may also have a requirement for measuring the measurement signal sent by the terminal device.

It can be seen from the above that a dedicated measurement signal is introduced in the NR system, and the terminal device #A transmits a dedicated measurement signal, and other devices such as the network device #2 and the terminal device #B that are not serving the terminal device #A are difficult to recognize the terminal device #A. The dedicated measurement signal is transmitted so that the dedicated measurement signal transmitted by the terminal device #A cannot be accurately measured.

Therefore, how the terminal device transmits the measurement signal for satisfying the measurement requirements of different devices becomes a technical problem to be solved.

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

The application scenario may also include a network device 104 and a terminal device 105 located within the coverage of the network device 104.

For example, the time unit may be a subframe, a slot, a mini-slot, or a Symbols, etc. The time unit may also be a plurality of subframes, a plurality of time slots, a plurality of mini-slots, or a plurality of symbols, and the like. Further, the time unit may be a time unit in the communication system for scheduling the transport block. For example, the time unit can be a transmission time interval (TTI).

Transmission direction: In the embodiment of the present application, the transmission direction includes at least an uplink transmission and a downlink transmission. The transmission direction may also include at least one of empty, unknown, and reserved. The transmission direction is uplink transmission, where the terminal device sends data to the network device. The downlink transmission direction refers to the network device sending data to the terminal device. The transmission direction is empty, which can be understood as: no data transmission. For example, assuming that the transmission direction of the subframe #1 is empty, it can be understood that the data is not transmitted on the subframe #1, and the subframe #1 is a vacant resource, and the vacant resource can be used for interference measurement, for example, can be used for the cross interference chain. Road measurement. The transmission direction is unknown/reserved, which can be understood as unknown, and is mainly used for forward compatibility considerations. For example, the subframe or time slot in which the transmission direction is unknown/reserved can be used for device-to-device (D2D) communication, measurement, and the like.

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

Non-downlink transmission: The non-downlink transmission in the transmission direction can be understood as: the transmission direction is uplink transmission, empty, unknown or reserved.

Bandwidth part (BP): In the embodiment of the present application, the BP may be a continuous resource in the frequency domain. For example, one bandwidth portion includes consecutive K (K>0) subcarriers; or one bandwidth portion is K (K>0) frequency domain resources in which non-overlapping consecutive resource blocks (RBs) are located; or A bandwidth part is a frequency domain resource in which M (M>0) non-overlapping consecutive resource block groups (RBGs) are located, and one RBG includes P (P>0) consecutive RBs.

Adjacent network devices: There are areas of common coverage between two network devices. The two network devices can be considered as adjacent network devices. Or the distance between the two network devices is less than the preset threshold, and the two network devices may be considered as adjacent network devices.

Dedicated measurement signal: This special measurement signal can refer to a measurement signal dedicated to a terminal device (or a measurement signal specific to a certain terminal device). The specific measurement signals sent by different terminal devices are different. For a detailed description of the dedicated measurement signals, refer to the related description above, which will not be repeated here for brevity.

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

For example, multiple terminal devices can be configured with the same sequence, ie, a common sequence is configured. This common sequence is a measurement signal. Any one of the plurality of terminal devices transmits the common sequence, and the terminal device can 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 an alternative example, the same time-frequency resource may be configured for the multiple terminal devices, and different cyclic shifts are configured for the multiple terminal devices.

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

Optionally, the multiple terminal devices may be terminal devices under one TRP coverage. Alternatively, the common measurement signal can be a TRP specific measurement signal. That is to say, multiple terminal devices belonging to one TRP can transmit the same measurement signal (or sequence). The TRP dedicated measurement signal is the same measurement signal sent by the plurality of terminal devices.

Other TRPs can learn the common sequence of the TRP. At least one of the plurality of terminal devices can transmit the common sequence (i.e., transmit a common measurement signal) to facilitate measurement of the common sequence by the receiving end of the common sequence.

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

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

Second type of measurement signal: This second type of measurement signal can be understood as another type of measurement signal. Optionally, the second type of measurement signal may be used for measurement by a device other than the network device of the local cell. Taking the communication scenario 100 as an example, the second type of measurement signal sent by the terminal device 102 can be used for at least one of the terminal device 103, the network device 104, and the terminal device 105, and the second type of measurement signal sent by the terminal device 105. Measurements may be made for at least one of the terminal device 102, the terminal device 103, and the network device 101.

The second network device is a different network device than the first network device. Optionally, 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, and the sequence of the second type of measurement signal is a second sequence, the first sequence being different from the second sequence. Optionally, the first sequence may be a dedicated sequence of the first terminal device, and the second sequence may be a common sequence of multiple terminal devices, where the multiple terminal devices include the first terminal device. That is, the first type of measurement signal may be a dedicated measurement signal of the first terminal device, and the second type of measurement signal may be a measurement signal common to a plurality of terminal devices, the plurality of terminal devices including the first terminal device.

Further optionally, the first sequence may be generated based on an identity (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 based on the first The ID of the user group to which the terminal device belongs is generated.

For a description of the first cyclic shift and the second cyclic shift, reference may be made to the related descriptions of the first sequence and the second sequence, which are not described 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 send a first type of measurement signal configuration time domain resource for the first terminal device.

The time domain resource configured by the first configuration information may include at least one time domain location. 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 location, an interval duration, and a number of repetitions. It is assumed that the initial time domain position is the symbol #F of the slot #S, the interval duration is T (T ≥ 0) slots, and the number of repetitions is M (M ≥ 2). The first resource may include M time domain locations (M symbols), where the starting position in the M time domain locations is the symbol #F of the slot #S, and the two adjacent ones of the M time domain locations There are T time slots between domain locations.

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

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

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

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

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

6) Scrambling code

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

For a description of the second configuration information, refer to the related description of the first configuration information, which is not described here for brevity.

The first network device sends the first configuration information and the second configuration information to the first terminal device. Correspondingly, 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 (message) 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 high layer signaling or may be carried in the physical layer signaling. For example, the first configuration information may be carried in radio resource control (RRC) signaling or medium access control (MAC) channel element (CE) signaling. High-level signaling (eg, RRC signaling) is semi-statically variable, which helps to reduce signaling overhead.

The first terminal device sends the first type measurement signal according to the first resource; the first terminal device sends the second type measurement signal according to the second resource; correspondingly, the first network The 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, in order to facilitate interference measurement and coordination, the time domain resource location, the frequency domain resource location, the sequence, the scrambling code, and the cyclic shift of the second type measurement signal may be pre-negotiated between the first network device and the second network device. At least one of (corresponding to the second network device determining the second resource), so that at least one of the second network device and the terminal device covered by the second network device can measure the second type according to the second resource The signal is measured.

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 by using the first network device, if the second terminal device is the second network device The covered terminal device, the second terminal device may determine the second resource by using the second network device.

In the embodiment of the present application, the first network device sends the two types of measurement signals to the first terminal device to configure the resources, and the first terminal device may send the first type of measurement signal according to the first resource, and send the second according to the second resource. Type measuring a signal, so that the first network device can 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 can measure the second type of measurement signal on the second resource Therefore, it is advantageous to meet the requirement that different devices measure the measurement signals of the first terminal device.

Further, the first type of measurement signal may be a measurement signal dedicated to the first terminal device, which facilitates the first network device to identify the received measurement signal (ie, identify the first type of measurement signal), which is beneficial to the first network device to efficiently Make measurements. The second type of measurement signal may be a measurement signal common to a plurality of terminal devices, facilitating at least one of the second network device and the second terminal device to identify the received measurement signal (ie, identifying the second type of measurement signal). This solution is beneficial to reduce the complexity of the device identification measurement signal.

In the above, it is described that the first network device can separately configure corresponding resources for the two types of measurement signals of the first terminal device. As described in detail below, how the first terminal device transmits the two types of measurement signals.

Way #1

The 220 can include:

Transmitting, by the first terminal device, the first type of measurement signal according to the configuration of the first configuration information;

The first terminal device sends the second type measurement signal according to the configuration of the second configuration information.

The following describes the first type of measurement signal sent by the first terminal device as an example. It should be understood that the manner in which the first terminal device sends the second type of measurement signal can refer to the manner in which the first terminal device sends the first type of measurement signal.

It is assumed that the first configuration information is used to indicate that the first resource corresponds to at least one time domain location, and the first terminal device may send the first type measurement signal in each of the at least one time domain location. Optionally, the first network device may receive the first type of measurement signal at each of the at least one time domain location.

It is assumed that the first configuration information is used to indicate that the first resource corresponds to one time domain location and a time period (ie, the first resource includes multiple time domain locations periodically). The first terminal device may periodically send the first type of measurement signal according to the time domain location and the time period. Optionally, the first network device can periodically receive the first type of measurement signal.

It is assumed that the first resource includes a time-frequency resource and the second resource includes a time-frequency resource. The time-frequency resource included in the first resource and the time-frequency resource included in the second resource may have overlapping portions. The overlapping portion of the time-frequency resource included in the first resource and the time-frequency resource included in the second resource may be understood as: the first resource and the second resource include the same time-frequency resource.

For example, it is assumed that the first resource includes the resource #R, and the time domain resource of the resource #R is the symbol #F of the slot #S, and the frequency domain resource of the resource #R is the first frequency domain resource, and the second resource also includes Resource #R. That is, the overlapping portion includes the resource #R. In this case, the first terminal device may transmit the first type measurement signal or the second type measurement signal in the overlapping portion based on at least one of the following ways.

1) Based on priority

Specifically, the first network device may pre-configure the priority of the first type measurement signal and the second type measurement signal. If the time-frequency resource for transmitting the first type of measurement signal and the time-frequency resource of the second type of measurement signal have overlapping portions, the measurement signal with higher priority may be transmitted at the overlapping portion according to the priority.

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

2) Based on instructions

Specifically, the method may further include:

The first network device sends the indication information to the first terminal device, where the indication information is used to indicate the first type measurement signal or the second type measurement signal; the first terminal device sends the indication information in the overlapping portion Indicated measurement signal.

For convenience of explanation, the “indication information for indicating the first type measurement signal or the second type measurement signal” may be referred to as “first indication information”.

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

Optionally, the first terminal device may receive the first indication information on a time unit where an overlapping portion (eg, resource #R) is located.

It should be understood that, assuming that resource #R is symbol #F of slot #S, the time unit in which resource #R is located is slot #S. It is assumed that the first terminal device receives the first indication information on the slot #S, and the first terminal device sends 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 the DCI on the first time unit, and sends the measurement signal indicated by the 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 send the measurement signal indicated by the first indication information in each overlapping portion of the at least one overlapping portion.

That is, in 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 transmits 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 has an overlapping portion with the time-frequency resource included in the second resource configured by the second configuration information, the first terminal device may be configured according to the priority or the first indication. Information, in which the corresponding measurement signal is transmitted.

Way #2

The first terminal device sends the first type measurement signal according to the first preset condition and the first resource;

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

For example, the first terminal device sends the second type measurement signal, and the second preset condition may include at least one of the following two types. It should be understood that the related description of the first preset condition can be referred to the related description of the second preset condition.

1) The first terminal device transmits data uplink.

That is, the first terminal device may determine whether to send the second type measurement signal on the time domain location included in the second resource according to whether the first terminal device subsequently sends data (upstream).

If the first terminal device determines the subsequent uplink transmission data of the first terminal device, the first terminal device may send the second type measurement signal in the time domain position included in the first resource before the first terminal device sends the data in the uplink.

On the other hand, if the first terminal device determines that the first terminal device does not perform uplink transmission, the first terminal device may not send the second type measurement signal in the time domain location included in the first resource.

Specifically, the second resource may include a first time unit, or the second resource includes a first symbol, where the first symbol belongs to the first time unit, and the first terminal device may be according to whether the second time unit after the first time unit is And transmitting, by the first terminal device, uplink data, determining whether to send the second type measurement signal on the first time unit, or determining whether to send the second type measurement signal on the first symbol of the first time unit .

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 includes a first time unit, which may be understood as: the second resource includes a part of the time domain resource in the first time unit. .

By way of example, assume that the second configuration information is used to indicate a time domain location as well as a time period. The time domain location is the symbol #F of the slot #S, and the time period is T slots. The second resource may include slot #S, slot #(S+T), slot #(S+2T). Wait for multiple time units. The first resource specifically includes a time slot #S symbol #F, a symbol #F of the slot #(S+T), and a symbol #F of the slot #(S+2T).

The 220 can include:

If the second time unit after the first time unit is used for the first terminal device to send data uplink, the first terminal device sends the second type measurement signal on the first time unit. Optionally, if the second time unit is configured by the first network device to be used for non-uplink transmission, or the second time unit is configured to be uplink transmission by the first network device, but is not used for uplink transmission of data by the first terminal device (ie, A terminal device does not transmit data uplink in the second time unit, and the first terminal device does not send the second type measurement signal on the first time unit.

Further optionally, the second time unit and the first time unit may be spaced apart by k time units (or the interval between the second time unit and the first time unit is less than or equal to k time units). The k value may be pre-agreed by the first network device and the first terminal device, and may be configured by the first network device for the first terminal device, which is not limited herein.

As an optional example, the second time unit and the first time unit may be separated by k time units. If the k value is equal to N (N≥1), whether the first terminal device sends the second type in the first time unit. The measurement signal depends on whether the Nth time unit (ie, the second time unit) after the first time unit is used for uplink transmission of data by the first terminal device. If the Nth time unit after the first time unit is used for uplink transmission of data by the first terminal device, the first terminal device sends a second type measurement signal on the first time unit. On the other hand, if the Nth time unit after the first time unit is not used for uplink transmission of data by the first terminal device, the first terminal device does not send the second type measurement signal on the first time unit.

As an alternative example, the interval between the second time unit and the first time unit is less than or equal to k time units, and if the k value is equal to N (N≥1), whether the first terminal device is sent in the first time unit The second type of measurement signal depends on whether there is a time unit in the N time units (ie, the second time unit) after the first time unit for the first terminal device to uplink transmit data. If any one of the N time units after the first time unit is used for uplink transmission of data by the first terminal device, the first terminal device sends the second type measurement signal on the first time unit. On the other hand, if any one of the N time units after the first time unit is not used for uplink transmission of data by the first terminal device, the first terminal device does not send the second type measurement signal on 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 uplink transmission of data by the first terminal device, and the first terminal device may determine to send the second type measurement signal uplink in the first time unit. .

As an optional 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 the second time unit has data reception. For example, if the second network device receives data on the second time unit, the second network device can receive the second type of measurement signal on the first time unit. For another example, if the second terminal device determines to receive data downlink 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 can report the measurement result, so that the network device serving the second terminal device can schedule the second terminal device to receive data in the second time unit according to the measurement result, which is beneficial to improving the second terminal device. The success rate of receiving data in the downlink.

As an alternative example, the second network device may determine whether to measure the second type of measurement signal in the first time unit according to whether the second time unit has downlink transmission data for the second network device. For example, if the second network device transmits data downstream in the second time unit, the second network device may measure the second type of measurement signal on 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 transmit data downlink in the second time unit, and the second network device may measure the second type measurement signal on the first time unit, and determine the second time unit according to the measurement result. The scheduling information of the downlink transmission, and the scheduling information is indicated to the terminal device of the local cell by using the DCI.

For example, the second network device can estimate the area or orientation of the first terminal device that sent the second type of measurement signal by estimating to the AOA or by scanning the wave array. The second network device may also determine, according to the scrambling code information or sequence information carried by the second type measurement signal, the cell where the first terminal device is located.

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

Optionally, the first network device sends, by using different terminal devices, at least one of a code domain, a frequency domain, and a cyclic shift of the second type of measurement signal, so as to facilitate at least one of the second network device and the second terminal device. Different terminal devices in the first network device can be distinguished according to code division, frequency division or cyclic shift.

For example, the frequency domain resource of the first network device includes multiple BPs, and each BP can be used to schedule m (m≥1) terminal devices. In a BP, the m terminal devices can use code division, frequency division, or Resource multiplexing is performed by means such as cyclic shift.

FIG. 5 is a schematic diagram of still another example of a communication method according to an embodiment of the present application. As shown in FIG. 5, each of the plurality of BPs may be used to schedule multiple terminal devices, and the frequency domain resources of the second type of measurement signals corresponding to different terminal devices in the same BP are different (ie, frequency division), or different terminal devices. Corresponding code domain resources are different (ie, code division), so that at least one of the second network device and the second terminal device may determine, according to the frequency division or the code division, the second transmission by each of the multiple terminal devices. Type measurement signal.

Optionally, the 220 can include:

The first terminal device sends a second type of measurement signal on the first time-frequency resource, where the time domain resource of the first time-frequency resource belongs to the first time unit and the frequency domain resource is the first frequency domain resource, and the second time-frequency resource The resource is used by the first terminal device to send data, the time domain resource of the second time-frequency resource belongs to the second time unit, and the frequency domain resource is the second frequency domain resource. The first frequency domain resource may be a complete set or a subset of the second frequency domain resource.

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

That is, the frequency domain resource used by the first terminal device to send the second type measurement signal on the first time unit may be determined according to the frequency domain resource used by the first terminal device to send data on the second time unit, or The frequency domain resource used by a terminal device to transmit the second type of measurement signal on the first time unit is a complete set or subset of 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 send the second type measurement signal on the first time unit by using the frequency domain resource of the uplink data sent by the first terminal device.

Optionally, the first terminal device may determine, by using multiple manners, whether the first terminal device sends data uplink.

For example, the method 200 can also 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 for uplink sending data of the first terminal device (or allocate a time domain resource, where the allocated The time domain resource is a part of the time domain resource in the second time unit; accordingly, before the first terminal device sends the second type measurement signal on the first time unit, the first terminal device receives the scheduling information.

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

Further, the scheduling information may be further configured to allocate a second frequency domain resource to the first terminal device, where the first terminal device may be the first time unit in the time domain and the first frequency domain in the frequency domain. A second type of measurement signal is sent on the first time-frequency resource of the resource, where the first frequency domain resource is a complete set or a subset of the second frequency domain resource.

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

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

For convenience of description, 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 send 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 the resource included in the second resource.

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

By way of example, assume that the second configuration information is used to indicate a time domain location as well as a time period. The time domain location 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), Multiple time domain positions such as symbol #F of slot #(S+2T).

If the first terminal device receives the second indication information in the time slot #S or the time slot before the time slot #S, the first terminal device may send the time slot #S according to the second indication information. The second type of measurement signal.

On the other hand, 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 send the second type measurement signal on the time slot #S. .

Here, after acquiring the second configuration information, the first terminal device needs to send 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 is equivalent to the trigger information, and is used to trigger the first terminal device to send the second type measurement signal on the corresponding resource.

It should be understood that the manner in which the first terminal device sends the first type of measurement signal may be referred to the manner in which the first terminal device sends the second type of measurement signal, which is not described herein for brevity.

The first configuration information may be configured to send the first type of measurement signal configuration first resource to the first terminal device, and the second configuration information may send the second type measurement signal configuration second resource to the first terminal device. In the actual communication process, there may be a case where the resource configured by the configuration information conflicts with the transmission direction configured by the first network device for the resource.

For example, assume that the second resource includes the 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 by the first network device to be non-uplink transmission, that is, the first symbol is used for non-uplink transmission of the first network device, and at this time, the first symbol The direction of the transfer conflicts.

For convenience of explanation, the transmission direction of the time domain location (for example, a symbol) corresponding to the configuration information may be in conflict with the transmission direction configured by the first network device for the time domain location, and the transmission direction of the time domain location may be recorded as conflict".

FIG. 7 is a schematic diagram showing an example of a 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 symbol #a of time unit #A, symbol #b of time unit #B, symbol #c of time unit #C, and symbol #d of time unit #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, and the symbol #C of the time unit #C is configured as unknown, time unit # D is configured by the first network device for uplink transmission.

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

For the second type of measurement signal, if the second type of measurement signal is interrupted due to a collision of the transmission direction of the time unit included in the second resource, the second network device or the second terminal device cannot obtain the situation in time, The second network device or the second terminal device continues to perform measurement, resulting in incorrect measurement results, thereby affecting the related coordination process and system performance. Therefore, when a collision occurs, preferably, the second terminal device continues to transmit the second type of measurement signal on the conflicting time domain location (e.g., symbol #a). Optionally, the first network device needs to use resource scheduling as much as possible to prevent the first terminal device from transmitting the second type of measurement signal on the time unit in which the collision occurs. For example, the first network device does not perform downlink transmission on the symbol #a.

That is, the second resource includes a first time domain location (or first symbol), and if the first time domain location is configured by the first network device to be used for non-uplink transmission, the first terminal The device (still) transmits the second type of measurement signal at the first time domain location.

For the first type of measurement signal, if the transmission direction of the time unit included in the first resource conflicts, the first terminal device may stop transmitting the first type measurement signal on the time unit in which the collision occurs.

For example, the first resource includes a symbol #e, and if the symbol #e is configured by the first network device to be used for non-uplink transmission, the first terminal device may stop transmitting on the symbol #e. The first type of measurement signal is described.

Optionally, the first terminal device may determine, by using multiple manners, a transmission direction configured by the first network device as a time unit. For example, the method 200 can include:

203. The first network device sends the transmission direction information. Correspondingly, 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 the at least one symbol, the plurality of symbols including the first symbol. Or the transmission direction information can be used to indicate the transmission direction of each symbol in the time unit. For example, if the time unit is a time slot, the transmission direction information may be slot format information (SFI). Optionally, each time unit may include transmission direction information indicating a transmission direction of each symbol in the time unit.

The first terminal device may determine, according to the transmission direction information, whether a transmission direction of the time domain location included in the resource configured by the configuration information conflicts.

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 can abandon this measurement and continue measuring. For example, it is assumed that the second terminal device is the terminal device that is covered by the second network device, and the second network device sends the third configuration information to the second terminal device, where the third configuration information is used to receive the measurement signal configuration for the second terminal device. The third resource includes the 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 a non-downlink transmission by the second network device, in which case the second terminal device may measure the received measurement signal on the first symbol, You can give up this measurement.

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

In the above, it is described that the first terminal device can separately transmit the first type measurement signal and the second type measurement signal according to the two configuration information. 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 measurement. Hereinafter, another example of the communication method of the embodiment of the present application will be described. The method is advantageous for improving the accuracy of the second terminal device for measuring the second type of measurement signal.

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 illustrates the detailed steps or operations of method 300, but these steps or operations are merely examples, and other embodiments of the present application may perform other operations or only some of the operations of FIG.

310. The network device determines a third resource, where the third resource belongs to a resource used by the terminal device to send a measurement signal. It should be understood that the terminal device does not refer to a certain fixed terminal device, but refers to a terminal device in the system. The resource for the terminal device to send the measurement signal is understood as: a resource used by the terminal device in the system to send the measurement signal. The resource for transmitting the measurement signal by the terminal device can be understood as a measurement signal resource pool. The network device may select a resource from the resource pool, and configure the selected resource to a certain terminal device, for example, configure the selected resource to the terminal device #A, and the terminal device #A may send the measurement signal according to the configured resource. .

For example, the resource used for the terminal device to send the measurement signal in the uplink may be the resource indicated by the uplink measurement resource configuration table. For example, the resources indicated by the SRS configuration table are described in detail in the uplink measurement resource configuration table.

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

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

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

The third configuration information is used to configure a third resource for receiving the measurement signal by the second terminal device. The third resource belongs to a resource that the second terminal device performs related measurement.

330. The second terminal device measures the received measurement signal on the third resource.

Optionally, 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 that sends the measurement signal. The method is advantageous for realizing time-frequency resource alignment of the transmitting end of the measurement signal and the receiving end of the measurement signal.

This is because, in the prior 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 RE pattern. For convenience of explanation, the "CSI-RS resource unit structure" may be referred to as "CSI-RS structure". The CSI-RS structure may be expressed 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, the (Y, Z) may be a plurality of structures such as (2, 1), (4, 1), (8, 1) (2, 2), (2, 4). In the prior art, the terminal device sends the SRS resource used by the measurement signal. The distribution of the SRS resources in the frequency domain is a comb-like distribution, and the interval between adjacent two subcarriers on each comb-shaped SRS resource is L. Alternatively, the L can be equal to 2 or 4. It can be seen that the structure of the CSI-RS resource and the SRS resource are not matched. 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 results.

For example, the first terminal device sends a measurement signal in the first resource, the time domain resource of the first resource is the symbol #1, and the frequency domain resource is the odd number subcarrier on the symbol #1 (1, 3, 5, 7... .) Based on the limit of the CSI-RS resource, the second terminal device performs measurement on a plurality of consecutive subcarriers on the symbol #1, thereby causing the measurement of the second terminal device to be inaccurate.

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

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

The network device serving the terminal device configures a downlink measurement resource parameter to the terminal device, and the terminal device uses the downlink measurement resource configuration table according to the parameter to obtain a specific time-frequency resource location where the downlink measurement reference signal is located. Specifically, the downlink measurement signal resource configuration table may include:

resourceConfig INTEGER(0..31)

subframeConfig INTEGER(0..154)

...

The parameter resourceConfig has a value range of 0-31, and the parameter can be used to determine a resource element (RE) and a symbol position of the CSI-RS reference signal in one subframe. The value of the parameter subframeConfig ranges from 0 to 154. This parameter can be used to determine the position of the subframe where the CSI-RS reference signal is located.

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

The network device serving the terminal device configures an uplink measurement resource parameter to the terminal device, and the terminal device combines the uplink measurement resource parameter with the uplink measurement resource configuration table to obtain a specific time-frequency resource location where the uplink measurement reference signal is located. 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 the parameter can be used to determine an SRS transmission period and a time domain (for example, 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 used by the terminal device to send the measurement signal may include the resource corresponding to the value of the parameter srs-ConfigIndex from 0-1023. The third configuration information may be used to indicate a specific value of the parameter srs-ConfigIndex (it is understood that the specific value indicated by the third configuration information belongs to 0-1023), and the 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 the 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 by different messages, and the terminal device obtains configuration parameters such as time-frequency resources of the downlink measurement reference signal according to the downlink configuration resource parameter and the downlink resource configuration table. The terminal obtains configuration parameters such as time-frequency resources of the uplink measurement reference signal according to the uplink configuration resource parameter and the uplink resource configuration table.

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

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

resourceConfig_r15 INTEGER(0..xx)

subframeConfig_r15 INTEGER(0..yy)

...

The parameter resourceConfig_r15 has a value range of 0-xx. The parameter includes a resource configuration for measuring a measurement signal sent from a network device, and a resource configuration of a measurement signal sent from another terminal device. The value of the parameter subframeConfig_r15 is 0-yy, and the parameter can be used to determine the subframe position where the resource configuration of the measurement signal sent from the network device is located. The third resource may be specifically used to indicate the value of the parameter resourceConfig_r15 and the value of the parameter subframeConfig_r15. The second terminal device may measure the measurement reference signal sent by the first terminal according to the third resource and the extended downlink measurement resource configuration table.

As another example of the present application, the second terminal device may separately store a measurement resource configuration table for measuring a measurement signal of the local network device and a measurement resource configuration table for measuring a measurement signal of the other terminal device.

The network device instructs the first terminal device to perform corresponding measurement by configuring measurement resource parameters.

The configuration table can look like this:

resourceConfig_r15 INTEGER(0..31)

subframeConfig_r15 INTEGER(0..154)

srs-ConfigIndex_r15 INTEGER(0..1023)

...

The second terminal determines a resource for measuring a measurement signal sent by the network device according to the parameter resourceConfig_r15 and the parameter subframeConfig_r15, and determines a resource for measuring the measurement signal sent by the other terminal device by using the parameter srs-ConfigIndex_r15.

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

If the second time unit after the first time unit is used by the second terminal device to receive data, the second terminal device measures the received measurement signal on the first time unit.

For details, refer to the related description of the method 200 above, and the details are not described herein for brevity.

Optionally, the second terminal device may determine, by using multiple manners, whether the second time unit is used by the second terminal device to receive data.

For example, optionally, the method 300 can include:

301, the network device sends scheduling information to the second terminal device, where the scheduling information is used to allocate a second time unit for receiving data by the second terminal device, where the scheduling information is further used by the second terminal. The device determines to transmit the second type of measurement signal on the first time unit.

Optionally, the network device in the method 300 may be the first network device or the second network device in the foregoing. The second terminal device in the method 200 can be the second terminal device in the method 200.

It should be understood that the detailed description of the method 300 can be referred to the related description of the method 200 above, and is not described herein for brevity.
