INTERFERENCE MEASUREMENT METHOD AND APPARATUS THEREOF

TECHNICAL FIELD

The present disclosure relates to the technical field of communication, and in particular, to an interference measurement method and apparatus.

BACKGROUND

In related technologies, with the development of radio frequency technology and digital domain interference cancellation technology, in some scenarios, a full-duplex technology with same frequency and time can be used on a network side, but due to factors such as size and cost of a terminal device, Time Division Duplex (TDD) or Frequency Division Duplex (FDD) technology is needed on a terminal device side.

In such scenario, since the network device may send and receive data by using same time and same frequency, mutual interference will occur between terminal devices in a same cell or adjacent cells. At present, there are no effective interference measurement manners, so the network device may send and receive data by using the full duplex technology with same frequency and time when the interference between terminal devices is serious, which leads to poor data transmission efficiency and low accuracy.

FIG. 1 shows an interference measurement method provided by an embodiment of the present disclosure. It shall be noted that, the interference measurement method of the embodiments of the present disclosure is performed by a first terminal device.

As shown in FIG. 1, the interference measurement method may include following steps.

Step 101, receiving a measurement signal by using a receiving beam in a physical downlink shared channel (PDSCH) of the first terminal device.

In an embodiment of the present disclosure, a second terminal device can send the generated measurement signal to the first terminal device, and the first terminal device can use the receiving beam of the physical downlink shared channel (PDSCH) to receive the measurement signal. The measurement signal may be various types of reference signals, or may be data signals, or may be other signals generated by the second terminal device. In addition, the receiving beam may be pre-configured, or may be indicated by a network device, or may be determined according to beam measurement, and the receiving beam may be a wide beam or a narrow beam, where a width of the beam can be flexibly configured according to actual needs, and the receiving beam may be a set of receiving beams generated by the first terminal device. It shall be noted that the second terminal device may be UE-A (User Equipment A), and the first terminal device may be UE-B (User Equipment B).

Step 102, determining an interference measurement result of the measurement signal.

Optionally, after receiving the measurement signal, the first terminal device can parse the measurement signal, and can determine the second terminal device sending the measurement signal according to a parsing result. The first terminal device can also determine measurement data of the measurement signal according to the received measurement signal, and can also determine whether the second terminal device sending the measurement signal causes interference to the first terminal device according to the measurement result.

As described above, based on the measurement signal received through the receiving beam on the PDSCH of the first terminal device, the interference measurement result of the measurement signal can be determined, so that the first terminal device can determine other terminal devices having strong mutual interference to the first terminal device, which is convenient for a network device to schedule, and data receiving performed by the first terminal device and data sending performed by other terminal devices having strong mutual interference are avoided to be performed at same frequency and same time, thereby improving data transmission efficiency and accuracy.

An embodiment of the present disclosure provides another interference measurement method. FIG. 2 is a schematic flowchart of another interference measurement method provided by an embodiment of the present disclosure, where the method can be performed by a first terminal device. The interference measurement method can be performed independently, or can be performed in combination with any embodiment or possible implementations in an embodiment in the present disclosure, or can be performed in combination with any technical solution in related arts.

As shown in FIG. 2, the interference measurement method may include following steps.

Step 201, receiving a measurement signal by using a receiving beam in a physical downlink shared channel (PDSCH) of the first terminal device.

Optionally, the first terminal device can use the receiving beam to receive the measurement signal sent by the second terminal device on a time-frequency resource configured by a network device. It should be noted that the time-frequency resource may be a time-frequency resource configured by a network device (such as a base station) through signaling, or may be a time-frequency resource in a time-frequency resource pool configured by a network device through signaling. In addition, among the time-frequency resources for receiving signals by the first terminal device and the time-frequency resources for sending signals by the second terminal device, there are resources with same time and same frequency.

Step 202, determining, according to a measurement type configured by a network device, a measurement manner corresponding to the measurement type.

Optionally, the measurement type configured by the network device is determined according to a signal type of the measurement signal configured by the network device.

In an embodiment, the network device does not configure the signal type of the measurement signal, and the measurement type configured by the network device is determined as a received signal strength indicator (RSSI).

In an embodiment, the network device configures the signal type of the measurement signal as an inter-UE cross link interference reference signal (UE-CLI-RS), and the measurement type configured by the network device includes at least one of: reference signal received power (RSRP), reference signal received quality (RSRQ), signal-to-interference plus noise ratio (SINR), and received signal strength indicator (RSSI).

Step 203, performing channel quality measurement on the measurement signal according to the measurement manner to determine measurement data corresponding to the measurement type.

In an embodiment of the present disclosure, the first terminal device performs channel quality measurement on the measurement signal according to the measurement manner determined in step 202, so as to determine the measurement data corresponding to the measurement type. The measurement data is data obtained by the first terminal device for measurement in a process of receiving the above measurement signal, and there are corresponding measurement data for each measurement type. When there are multiple measurement types, measurement data corresponding to each measurement type is determined, so as to obtain multiple pieces of measurement data.

Optionally, in response to that the measurement type is RSSI, the measurement data is RSSI when the first terminal device receives the measurement signal; in response to that the measurement type is RSRP, the measurement data is RSRP when the first terminal device receives the measurement signal; in response to that the measurement type is RSRQ, the measurement data is RSRQ when the first terminal device receives the measurement signal; in response to that the measurement type is SINR, the measurement data is SINR when the first terminal device receives the measurement signal.

It should be noted that RSRQ is N times of a ratio of RSRP to RSSI, RSRQ=N*RSRP/RSSI, where N represents a number of RBs (resource blocks) contained in a measurement bandwidth of RSSI, and RSRQ can reflect a relative size between the received measurement signal and interference; SINR may be a ratio of strength of the measurement signal to strength of an interference signal (noise and interference) received by the first terminal device.

Step 204, comparing the measurement data and a measurement threshold corresponding to the measurement type configured by the network device.

In an embodiment of the present disclosure, the measurement data may include one or more of RSRP, RSRQ, SINR and RSSI, and measurement thresholds corresponding to different data in the measurement data are also different. It should be noted that the measurement threshold corresponding to the measurement data is configured by the network device or determined according to a protocol.

Step 205, in response to that the measurement data is greater than or equal to the measurement threshold, determining that an interference result is that the measurement signal belongs to to-be-reported interference signals.

As an example, when the measurement data includes one of RSRP, RSRQ, SINR or RSSI, and when the measurement data is greater than or equal to the measurement threshold corresponding to the measurement data, the interference measurement result can be determined as that the measurement signal belongs to to-be-reported interference signals of the first terminal device.

As another example, when the measurement data includes two or more of RSRP, RSRQ, SINR and RSSI, the measurement thresholds corresponding to different data in the measurement data can be obtained respectively, and when any data in the measurement data is greater than the corresponding measurement threshold, the interference measurement result can be determined as that the measurement signal belongs to to-be-reported interference signals of the first terminal device.

Further, in response to that a comparing result is that the measurement data is less than the measurement threshold, the interference result is determined as that the measurement signal does not belong to to-be-reported interference signals.

As an example, when the measurement data includes one of RSRP, RSRQ, SINR or RSSI, and when the measurement data is less than the measurement threshold corresponding to the measurement data, the interference measurement result can be determined as that the measurement signal does not belong to to-be-reported interference signals of the first terminal device.

As another example, when the measurement data includes two or more of RSRP, RSRQ, SINR and RSSI, when all the data in the measurement data are less than the corresponding measurement threshold, the interference measurement result can be determined as that the measurement signal does not belong to to-be-reported interference signals of the first terminal device.

Step 206, generating reporting data according to a receiving time period of the measurement signal and the measurement data.

The receiving time period of the measurement signal may be slot indexes of slots for receiving the measurement signal, or may be other indication information that can determine time information for receiving the measurement signal.

In an embodiment, in response to that the signal type of the measurement signal is UE-CLI-RS, the first terminal device parses the UE-CLI-RS, and a terminal device identifier of the second terminal device that sent the UE-CLI-RS can be obtained according to a parsing result.

Further, the reporting data is generated according to the terminal device identifier, the receiving time period of UE-CLI-RS and the measurement data.

Step 207, sending the reporting data to the network device.

A channel for sending the reporting data is a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH).

As described above, a receiving beam is used to receive a measurement signal; a measurement manner corresponding to a measurement type is determined according to the measurement type configured by a network device; where when the network device does not configure a signal type of the measurement signal, the measurement type is RSSI; channel quality measurement is performed on the measurement signal according to the measurement manner so as to determine measurement data corresponding to the measurement type; when the measurement data is greater than or equal to a measurement threshold, an interference result is determined as that the measurement signal belongs to to-be-reported interference signals; reporting data is generated according to a receiving time period of the measurement signal and the measurement data; and the reporting data is sent to the network device.

When the network device configures the signal type of the measurement signal as UE-CLI-RS, the measurement type includes at least one of RSRP, RSRQ, SINR or RSSI; channel quality measurement is performed on the measurement signal according to the measurement manner corresponding to the measurement type, so as to determine measurement data corresponding to the measurement type; when the measurement data is greater than or equal to a measurement threshold, an interference result is determined as that the UE-CLI-RS belongs to to-be-reported interference signals; the UE-CLI-RS is parsed to obtain a terminal device identifier; reporting data is generated according to the terminal device identifier, a receiving time period of the UE-CLI-RS and the measurement data; and the reporting data is sent to the network device. According to the method, a second terminal device that sent the UE-CLI-RS is determined by parsing the UE-CLI-RS, and it is determined whether the UE-CLI-RS belongs to to-be-reported interference measurement signals of the first terminal device according to the measurement data of the UE-CLI-RS, and when the UE-CLI-RS belongs to the to-be-reported interference measurement signals of the first terminal device, the terminal device identifier of the second terminal device parsed from the UE-CLI-RS, the receiving time period of the UE-CLI-RS and the measurement data are sent to the network device. In such way, the first terminal device can determine the second terminal device having mutual interference with the first terminal device, which is convenient for the network device to schedule, thereby improving data transmission efficiency and accuracy.

The interference measurement method of the embodiments of the present disclosure is performed by the first terminal device, and by receiving the measurement signal through the receiving beam, the interference measurement result of the measurement signal can be determined, so that the first terminal device can determine the second terminal device having mutual interference with the first terminal device, which is convenient for the network device to schedule, and data receiving performed by the first terminal device and data sending performed by the second terminal device are avoided to be performed at same frequency and same time, thereby improving data transmission efficiency and accuracy.

An embodiment of the present disclosure provides another interference measurement method. FIG. 3 is a schematic flowchart of another interference measurement method provided by an embodiment of the present disclosure. The interference measurement method can be performed by a second terminal device, for example, the second terminal device may be UE-A.

As shown in FIG. 3, the interference measurement method may include following steps.

Step 301, generating a measurement signal.

The measurement signal maybe various types of reference signals, or may be data signals, or may be other signals generated by the second terminal device. In addition, the measurement signal may be generated according to configuration in a network device.

Step 302, sending the measurement signal by using a sending beam in a sending beam set.

The sending beam set may be pre-configured, or may be configured by a network device, or may be determined through beam measurement.

As described above, the second terminal device generates the measurement signal, and sends the measurement signal through the sending beam in the sending beam set. The first terminal device can receive the measurement signal through a receiving beam, and can determine the second terminal device having mutual interference with the first terminal device according to the received measurement signal, which is convenient for the network device to schedule, and data receiving performed by the first terminal device and data sending performed by the second terminal device are avoided to be performed at same frequency and same time, thereby improving data transmission efficiency and accuracy.

The interference measurement method can be performed by a second terminal device.

As shown in FIG. 4, the interference measurement method may include following steps.

Step 401, generating a measurement signal.

In an embodiment, in response to that the network device configures a signal type of the measurement signal as UE-CLI-RS, the UE-CLI-RS is generated according to a terminal device identifier of the second terminal device.

Optionally, as an example, UE-CLI-RS r(m) can be generated according to following formula:

$r (m) = \frac{1}{\sqrt{2}} (1 - 2 c (2 m)) + j \frac{1}{\sqrt{2}} (1 - 2 c (2 m + 1));$

where m and n represents an integer greater than or equal to 0 respectively; c(n) can be generated according to the following formula:

$c (n) = (x_{1} (n + N_{C}) + x_{2} (n + N_{C})) \mod 2;$

$x_{1} (n + 31) = (x_{1} (n + 3) + x_{1} (n)) \mod 2;$

$x_{2} (n + 31) = (x_{2} (n + 3) + x_{2} (n + 2) + x_{2} (n + 1) + x_{2} (n)) \mod 2;$

where, N_C=1600; n represents an integer greater than or equal to 0, x₁(0)=1, x₁(n)=1, 2, . . . 30, an initial value of x₂(n) is determined according to an identifier, a wireless frame number, a sub-frame number and other time-related parameters of the second terminal device.

Optionally, as an example, UE-CLI-RS r(n) can be generated according to following formula:

$r (n) = e^{j α n} \overline{r} (n), 0 \leq n \leq N;$

${\overline{r}}_{q} (n) = x_{q} (n \mod N);$

$x_{q} (m) = e^{- j \frac{π qm (m + 1)}{N}};$

where, N represents a sequence length, n represents an integer greater than or equal to 0, and less than or equal to N, values of α, q can be determined according to an identifier, a wireless frame number, a sub-frame number and other time-related parameters of the second terminal device respectively.

In another implementation, in response to that the network device does not configure a signal type of the measurement signal, the measurement signal of any signal type is generated.

Optionally, the measurement signal may be a data signal, or may be a reference signal, or may be other signals generated by the second terminal device. That is, the second terminal device can generate a signal of any type and take the signal as the measurement signal.

Step 402, receiving a reference signal configured by a network device, and determining a receiving beam for receiving the reference signal.

Optionally, the network device uses abeam in abeam set to send the configured reference signal to the second terminal device, and the second terminal device uses the receiving beam to receive the reference signal, and determines an optimal receiving beam corresponding to each beam. The beam set may be pre-configured, or may be determined according to information of the second terminal device. The network device adopts the beam in the beam set to send a reference synchronization signal block (SSB) or a channel state information reference signal (CSI-RS).

In an implementation, the network device configures the reference SSB, the second terminal device receives the reference SSB and determines a receiving beam of the reference SSB.

In another implementation, the network device configures the CSI-RS, the second terminal device receives the CSI-RS, and determines a receiving beam of the CSI-RS.

The receiving beam is determined in step 402.

Optionally, using reciprocity of beams, the sending beam set is generated according to the sending beam corresponding to the determined receiving beam.

Step 404, sending the measurement signal by using the sending beam in the sending beam set.

The sending beam set is the sending beam set generated in step 403.

Optionally, each sending beam in the sending beam set is used to send the measurement signal.

Optionally, a time-frequency resource for sending the measurement signal is a time-frequency resource configured by the network device, or a time-frequency resource selected from a time-frequency resource pool configured by the network device.

In an embodiment of the present disclosure, the second terminal device sends the generated measurement signal by using the sending beam in the sending beam set configured by the network device.
