Next, a communication system to which the embodiment of the present application is applied will be described with reference to fig. 1.

Fig. 1 is a schematic architecture diagram of a communication system according to an embodiment of the present application. Referring to fig. 1, the network device 101 and the terminal device 102 are included. The network device 101 may periodically transmit a beam to the terminal device 102, where the beam may carry a signal of a preset type. For example, a beam may carry Synchronization signals and PBCH blocks (SSBs) or Channel State Reference signals (CSIRS). Wherein, the terminal device 102 performs measurement and interference cancellation on the SSB signal in the idle state, and the terminal device 102 performs measurement and interference cancellation on the CSIRS signal in the traffic state.

In the related art, when receiving a plurality of beams, the terminal device may perform interference cancellation processing on each beam at a time according to a receiving time of the beam, for example, when receiving the beam, the terminal device needs to calculate interference of each beam before receiving the beam on the beam, and then perform interference cancellation. However, this will increase the time duration for the terminal device to perform interference cancellation, resulting in low efficiency for the terminal device to perform interference cancellation.

In order to solve the technical problem of low efficiency of interference cancellation performed by a terminal device in the related art, embodiments of the present application provide a grouping method for cell interference cancellation, in which the terminal device determines a first beam set, wherein the first beam set comprises a plurality of beams, each beam comprises a signal of a preset type, and according to the sequence of the receiving time, sorting the beams in the first set of beams to obtain a third set of beams, dividing the third set of beams into at least one second set of beams, wherein the difference of the receiving time of any two beams in the second beam set is less than or equal to a first preset time length, and the deviation of the wave beams in each second wave beam set in the time domain is smaller, whether the wave beams in each second wave beam set have the condition of interference elimination in the frequency domain is judged, and then the wave beams meeting the condition of interference elimination are subjected to interference elimination. Therefore, the terminal equipment can quickly and effectively convert the wave beams in the second wave beam set into the frequency domain for interference elimination through one-time conversion processing, and carry out interference elimination processing on the wave beams meeting the interference elimination condition, so that the time length for interference elimination of the terminal equipment is reduced, and the efficiency for interference elimination of the terminal equipment can be improved.

The technical means shown in the present application will be described in detail below with reference to specific examples. It should be noted that the following embodiments may exist alone or in combination with each other, and the description of the same or similar contents is not repeated in different embodiments.

Fig. 2 is a flowchart illustrating a grouping method for cell interference cancellation according to an embodiment of the present disclosure.

Referring to fig. 2, the method may include:

s201, determining a first beam set.

The execution main body of the embodiment of the application may be a terminal device, and may also be a grouping device for cell interference cancellation arranged in the terminal device. Optionally, the grouping unit for cell interference cancellation may be implemented by software, or may be implemented by a combination of software and hardware.

The first set of beams includes a plurality of beams, each beam including a signal of a preset type. Wherein the beam may be an electromagnetic wave. For example, in the fifth generation mobile communication technology (5G), a base station of a cell may send electromagnetic waves to a terminal device to realize transmission of signals. The preset type of signal may be a reference signal carried in a beam. Optionally, in the 5G application field, the preset type of signal may be an SSB signal or a CSIRS signal. The terminal device measures and eliminates interference on the SSB signal in an idle state, and measures and eliminates interference on the CSIRS signal in a service state. Optionally, the network device transmission beam may include an SSB signal, may also include a CSIRS signal, and may also include an SSB signal and a CSIRS signal at the same time.

The first beam set may include multiple beams transmitted by multiple network devices, or may include multiple beams transmitted by the same network device. The beams in the first set of beams all comprise the same preset type of signal. For example, if the predetermined type of signal is an SSB signal, each beam in the first set of beams includes an SSB signal; if the preset type of signal is a CSIRS signal, each beam in the first set of beams includes a CSRIS signal. For example, if the terminal device needs to perform interference cancellation on the SSB signals in the beams, each beam in the first beam set includes an SSB signal; if the terminal device needs to perform interference cancellation on the CSIRS signals in the beams, each beam in the first beam set includes the CSIRS signals.

Optionally, the terminal device may obtain a plurality of beams through the allocated receiving period, and further determine the first beam set in the plurality of beams according to the preset type of signal. For example, the terminal device may receive multiple beams in the reception period, and if the signal of the preset type is an SSB signal, the terminal device may determine a beam including the SSB signal in the multiple beams as the first beam set, and if the signal of the preset type is a CSIRS signal, the terminal device may determine a beam including the CSIRS signal in the multiple beams as the first beam set.

S202, grouping the beams in the first beam set to obtain at least one second beam set.

The difference of the receiving time of any two wave beams in the second wave beam set is less than or equal to a first preset time length. And the receiving time is the time when the terminal equipment receives the beam. For example, if the network device transmits a beam to the serving cell at time 1 and the terminal device receives the beam transmitted by the network device at time 2, the reception time is time 2. For example, if the second beam set includes beam a, beam B, and beam C, the difference between the receiving time of beam a and the receiving time of beam B is less than or equal to the first preset duration, the difference between the receiving time of beam B and the receiving time of beam C is less than or equal to the first preset duration, and the difference between the receiving time of beam a and the receiving time of beam C is less than or equal to the first preset duration. Alternatively, the first preset time period may be a time period required for a Fast Fourier Transform (FFT). Optionally, the first preset duration may be any preset duration, and in the process of practical application, the preset first preset duration is shorter. For example, the first preset time period may be 1 microsecond, 1 nanosecond, or the like, so that power consumption during processing by the terminal device may be reduced.

The beams in the first set of beams may be grouped according to the following feasible implementation manners, resulting in at least one second set of beams: a receive time instant for each beam in the first set of beams is determined. For example, when the terminal device receives a beam in a receiving period, the receiving time of the beam in the receiving period may be recorded, and the receiving time of each beam may be obtained. And determining a second beam set according to the receiving time of each beam and the first preset time length.

Optionally, the second set of beams may be obtained according to the following feasible implementation manners: and sequencing the plurality of beams in the first beam set according to the receiving time of each beam to obtain a third beam set. And obtaining a second wave beam set according to the third wave beam set and the first preset time length. Wherein the plurality of beams in the third set of wavelengths are arranged according to the reception time. Optionally, the order in which the terminal device receives the beams may be determined according to the position of each beam in the third set of beams. For example, the first beam in the third set of beams is the beam with the earliest receive time instant, and the last beam in the third set of beams is the beam with the latest receive time instant.

Optionally, the third beam set may include a receiving time corresponding to each beam. For example, the third beam set includes beams arranged in the order of the reception time, and may further include an accurate reception time corresponding to each beam.

Next, a schematic process diagram of obtaining the third beam set according to the receiving time of each beam in the first beam set is described in detail with reference to fig. 3.

Fig. 3 is a schematic diagram of a third beam set according to an embodiment of the present application. Please refer to fig. 3, which includes: a first set of beams and a third set of beams. The first and third sets of beams include beam 1, beam 2, beam 3, beam 4, and beam 5. The receive time of beam 1 is earlier than the receive time of beam 2, the receive time of beam 2 is earlier than the receive time of beam 3, the receive time of beam 3 is earlier than the receive time of beam 4, and the receive time of beam 4 is earlier than the receive time of beam 5. Wherein, the beam 1, the beam 2, the beam 3, the beam 4 and the beam 5 all include signals of preset types.

Referring to fig. 3, each beam in the first beam set is sorted according to the receiving time of each beam in the first beam set to obtain a third beam set. The first beam in the third set of beams is beam 1, the second beam is beam 2, the third beam is beam 3, the fourth beam is beam 4, and the last beam is beam 5. The order in which the beams are received by the terminal device may be determined in dependence on the position of each beam in the third set of beams.

Optionally, the second beam set is obtained according to the third beam set and the first preset duration, where the two conditions are as follows:

case 1: the difference between the receiving time of the first beam and the receiving time of the last beam in the third set of beams is less than or equal to the first preset duration.

When the difference between the receiving time of the first beam and the receiving time of the last beam in the third beam set is less than or equal to the first preset time length, the second beam set may be determined according to the following feasible implementation manners: the third set of beams is determined as the second set of beams. The first beam in the third beam set is a beam with the earliest receiving time in the plurality of beams, and the last beam in the third beam set is a beam with the latest receiving time in the plurality of beams. For example, in the third beam set, since the terminal device orders the plurality of beams according to the reception time of the plurality of beams, the reception time of the first beam in the third beam set is the earliest and the reception time of the last beam is the latest.

When the difference between the receiving time of the first beam and the receiving time of the last beam in the third beam set is smaller than or equal to the first preset time length, it indicates that the receiving times of all beams in the third beam set are close at this time, and there is a possibility of mutual interference between the beams, so that a plurality of beams in the third beam set may be determined as the second beam set.

In this case, a process of obtaining the second beam set from the third beam set will be described with reference to fig. 4.

Fig. 4 is a schematic diagram of a process of determining a second beam set according to an embodiment of the present application. Referring to fig. 4, a third set of beams and a second set of beams are included. Wherein the third set of beams and the second set of beams include beam 1, beam 2, beam 3, beam 4, and beam 5. The receive time of beam 1 is earlier than the receive time of beam 2, the receive time of beam 2 is earlier than the receive time of beam 3, the receive time of beam 3 is earlier than the receive time of beam 4, and the receive time of beam 4 is earlier than the receive time of beam 5.

Referring to fig. 4, a first beam in the third beam set is beam 1, a last beam in the third beam set is beam 5, and since a difference between a receiving time of beam 1 and a receiving time of beam 5 is smaller than a first preset duration, the third beam set can be determined as the second beam set.

Case 2: the difference between the receiving time of the first beam and the receiving time of the last beam in the third set of beams is greater than the first preset duration.

When the difference between the receiving time of the first beam and the receiving time of the last beam in the third beam set is greater than the first preset time length, at least two second beam sets may be determined according to the following feasible implementation manners: and determining an ith start beam and an ith end beam in the third beam set according to the first preset time length, wherein the (i + 1) th start beam is the first beam after the ith end beam, i sequentially takes 1, 2 … … and N, and N is an integer greater than 1. Optionally, the maximum value of N is such that the start beam and the end beam all allocate beams in the third beam set to the second beam set. For example, if the third set of beams includes 3 start beams and 3 end beams, the third set of beams may be divided into 3 second sets of beams; if the third beam set includes 5 start beams and 5 end beams, the third beam set may be divided into 5 second beam sets. For example, in the third set of beams, the first start beam is beam a, the first end beam is beam B, the next beam of beam B is beam C, and the second start beam is beam C.

Since the determining manners of the start beam and the end beam in each group are the same, determining the first start beam and the first end beam in the third beam set may obtain all the start beams and the end beams in the third beam set according to the same manner.

When i is 1, the 1 st start beam and the 1 st end beam may be determined in the third beam set according to the following feasible implementation manners: a first beam of the third set of beams is determined as a first start beam. For example, the beam with the earliest reception time in the third beam set is used to determine the first start beam. Since the beams in the third set of beams are arranged in order of reception time instants, the first beam in the third set of beams is the beam with the earliest reception time instant.

And determining a first ending beam in the third beam set according to the receiving time of the first starting beam and the first preset time length. Optionally, a time difference between the receiving time of the first start beam and the receiving time of each beam in the third beam set may be obtained, and then the first end beam is determined in the third beam set according to the time difference and the first preset duration. For example, when the receiving time of the first start beam is time a, the receiving time of beam B is time B, the receiving time of beam C is time C, and beam B is the next beam of beam C, if the time difference between time a and time B is less than or equal to the first preset duration, and the time difference between time a and time C is greater than the first preset duration, beam C is determined as the first end beam.

The process of determining the start beam and the end beam is described in detail below with reference to fig. 5.

Fig. 5 is a schematic diagram of a process for determining a start beam and an end beam according to an embodiment of the present application. Please refer to fig. 5, which includes a third set of beams. Wherein the third set of beams includes beam 1, beam 2, beam 3, beam 4, beam 5, beam 6, and beam 7. The receive time of beam 1 is earlier than the receive time of beam 2, the receive time of beam 2 is earlier than the receive time of beam 3, the receive time of beam 3 is earlier than the receive time of beam 4, the receive time of beam 4 is earlier than the receive time of beam 5, the receive time of beam 5 is earlier than beam 6, and the receive time of beam 6 is earlier than beam 7.

Referring to fig. 5, the beam 1 is determined as a first start beam, and the beam 4 is determined as a first end beam when the difference between the receiving time of the beam 1 and the receiving time of the beam 4 is smaller than a first preset time duration and the difference between the receiving time of the beam 1 and the receiving time of the beam 5 is larger than the first preset time duration. Since beam 4 is the first end beam, beam 5 is determined as the second start beam and beam 7 is determined as the second end beam.

Optionally, the third beam set is grouped according to the N start beams and the N end beams to obtain N second beam sets, and the following feasible implementation manners may be adopted: determining an ith start beam, beams between the ith start beam and the ith end beam, and an ith end beam as an ith second beam set. For example, the first second set of beams includes a first start beam, a first end beam, and a beam between the first start beam and the first end beam; the nth second beam set includes an nth start beam, an nth end beam, and a beam between the nth start beam and the nth end beam.

In the feasible implementation manner, the i groups of start beams and end beams are determined in the third beam set according to the first preset time length, and then the third beam set can be accurately grouped according to the start beams and the end beams to obtain the second beam set, so that the accuracy of the second beam set is improved, and the efficiency of interference elimination can be improved.

The process of determining the second beam in this case is described in detail below in conjunction with fig. 6.

Fig. 6 is a schematic diagram of another process for determining the second beam set according to the embodiment of the present application. Referring to fig. 6, a third set of beams is included. Wherein the third set of beams includes beam 1, beam 2, beam 3, beam 4, beam 5, beam 6, and beam 7. The receive time of beam 1 is earlier than the receive time of beam 2, the receive time of beam 2 is earlier than the receive time of beam 3, the receive time of beam 3 is earlier than the receive time of beam 4, the receive time of beam 4 is earlier than the receive time of beam 5, the receive time of beam 5 is earlier than beam 6, and the receive time of beam 6 is earlier than beam 7.

Referring to fig. 6, in the third beam set, beam 1 is determined as the first start beam, beam 4 is determined as the first end beam, beam 5 is determined as the second start beam, and beam 7 is determined as the second end beam. The third set of beams may be split into a second set of beams a and a second set of beams B according to two start beams and two end beams. Wherein, the second beam set a includes a first start beam: beam 1, first end beam: beam 4, and beams 2 and 3 between beam 1 and beam 4. The second set of beams B includes a second start beam: beam 5, second end beam: beam 7, and beam 6 between beam 5 and beam 7.

And S203, determining a target beam set in the at least one second beam set.

The beams in the target beam set are the beams that need interference cancellation. For example, when the beam a, the beam B, and the beam C are included in the second beam set, if the beam a and the beam B interfere with each other, the beam a and the beam B are included in the target beam set.

The target set of beams may be determined according to the following possible implementations: frequency domain information for each beam in the second set of beams is obtained. Wherein, the frequency domain information is used for indicating the frequency domain position of the beam transmission. For example, if the beam may be transmitted in a 100 gigahertz (GHz) band, the frequency domain information may indicate a transmission location of the beam in the 100GHz band. For example, a beam may be transmitted within the last 10GHz of a band of 100 GHz.

Optionally, the frequency domain information of the beam may be determined according to the following feasible implementation manners: and determining the frequency domain information of the wave beam according to the preset type of signals carried in the wave beam. For example, when performing interference cancellation on CSIRS signals of beams, each beam in the first beam set includes a CSIRS signal, and thus, frequency domain information of the beam may be obtained by analyzing the CSIRS signal of each beam in the second beam set; when the interference cancellation is performed on the SSB signals of the beams, each beam in the first beam set includes the SSB signal, and therefore, the frequency domain information of the beam can be obtained by analyzing the SSB signal of each beam in the second beam set.

And determining a target beam set according to the frequency domain information of each beam. Optionally, the target beam set may be determined according to the following feasible implementation manners: it is determined whether a third beam is included in the second set of beams based on the frequency domain information for each beam. Wherein the frequency domain information of the third beam and the frequency domain information of each beam in the second set of beams are non-overlapping. For example, the second beam set includes a beam a, a beam B, and a beam C, the preset frequency band is 10GHz, if the frequency domain information of the beam a indicates that the beam a is transmitted in the first 3GHz in the preset frequency band, the frequency domain information of the beam B indicates that the beam B is transmitted in the first 6GHz in the preset frequency band, and the frequency domain information of the beam C indicates that the beam C is transmitted in the last 2GHz in the preset frequency band, the frequency domain information between the beam a and the beam B has an overlapping portion, and the frequency domain information of the beam C does not overlap with the frequency domain information of the beam a and the beam B, so the beam C is a third beam.

If not, determining the second beam set as the target beam set. For example, if the frequency domain information of any two beams in the second set of beams overlap, the second set of beams is determined as the target set of beams. And if so, determining the beams in the second beam set except the third beam as the target beam set. For example, the second beam set includes a beam a, a beam B, and a beam C, and if the beam C is a third beam, the target beam set determined according to the second beam set includes the beam a and the beam B. Optionally, since the frequency domain information of the third beam and the frequency domain information of each beam in the second beam set are not overlapped, the third beam does not cause signal interference to other beams in the second beam set, and is not interfered by signals of other beams in the second beam set, and interference elimination processing on the third beam is not required. Optionally, if all the beams in the second beam set are the third beams, the interference cancellation processing is not performed on the beams in the second beam set.

Next, the process of determining the third beam is described in detail with reference to fig. 7.

Fig. 7 is a schematic diagram of a process of determining a third beam according to an embodiment of the present disclosure. The second set of beams includes beam a, beam B, and beam C. Referring to fig. 7, the predetermined frequency band is a transmission range of the beam carrier frequency. For example, the preset frequency band may be a frequency band of 100GHz, the transmission frequency domain of the beam a and the transmission frequency domain of the beam B have an overlapping portion, the transmission frequency domain of the beam C does not overlap with the transmission frequency domains of the beam a and the beam B, and the beam C is a third beam.

S204, carrying out interference elimination processing on the beams in the target beam set.

The interference cancellation process is used to cancel signal interference between beams. For example, signals between beams transmitted by base stations of co-frequency neighboring cells interfere with each other, and signal interference between beams can be reduced through interference cancellation processing, so that accuracy of cell measurement can be improved.

The beams may be subjected to interference cancellation processing by a mode of interference cancellation. The interference cancellation mode is used for indicating a method for performing interference cancellation. For example, the SSB signal may be interference canceled using an interference cancellation mode of a Physical Broadcast Channel (PBCH).

Optionally, the same interference cancellation mode is used for the same target beam set. For example, the target beam set includes a beam a, a beam B, and a beam C, and when interference cancellation is performed on the beams in the target beam set, the same interference cancellation mode is used to perform interference cancellation processing on the beam a, the beam B, and the beam C.

The embodiment of the present application provides a grouping method for cell interference cancellation, where a first beam set is determined, where the first beam set includes a plurality of beams, each beam includes a signal of a preset type, a receiving time of each beam in the first beam set is determined, the plurality of beams in the first beam set are sorted according to the receiving time of each beam, a third beam set is obtained, if a difference between the receiving time of a first beam and the receiving time of a last beam in the third beam set is less than or equal to a first preset duration, the third beam set is determined as a second beam set, and if a difference between the receiving time of the first beam and the receiving time of the last beam in the third beam set is greater than the first preset duration, an ith start beam and an ith end beam are determined in the third beam set according to the first preset duration, the i +1 th initial beam is a first beam after the i th end beam, i sequentially takes 1, 2, … … and N, N is an integer greater than 1, the third beam set is grouped according to the N initial beams and the N end beams to obtain N second beam sets, in at least one second beam set, a target beam set is determined, and interference elimination processing is performed on beams in the target beam set. Therefore, the terminal equipment can quickly and effectively convert the wave beams in the second wave beam set into the frequency domain for interference elimination through one-time conversion processing, and carry out interference elimination processing on the wave beams meeting the interference elimination condition, so that the time length for interference elimination of the terminal equipment is reduced, and the efficiency for interference elimination of the terminal equipment can be improved.

Based on the embodiment shown in fig. 2, the following describes the grouping method for cell interference cancellation in detail with reference to fig. 8.

Fig. 8 is a flowchart illustrating another grouping method for cell interference cancellation according to an embodiment of the present application. Referring to fig. 8, the method may include:

s801, determining a first beam set.

The first set of beams includes a plurality of beams, each beam including a signal of a preset type.

It should be noted that the execution process of S801 may refer to the execution process of S201, and details are not described here.

S802, determining the receiving time of each beam in the first beam set.

The receiving time is the time when the terminal equipment receives the beam. For example, if the network device transmits a beam to the serving cell at time 1 and the terminal device receives the beam transmitted by the network device at time 2, the reception time is time 2.

Optionally, because the terminal device receives the SSB signal in the beam in the idle state and receives the CSIRS signal in the beam in the service state, for the SSB signal received in the idle state, the terminal device may receive the SSB signal in a concentrated manner within a time period of an idle period, interference between the SSB signals is large, and for the CSIRS signal received in the service state, each time domain position and period of the CSIRS signal are configured independently, so that when the terminal device receives the CSIRS signal, interference between the CSIRS signals is small.

And S803, determining a second beam set according to the receiving time of each beam and the first preset time length.

Optionally, the second set of beams may be determined according to the following feasible implementation: and sequencing the plurality of beams in the first beam set according to the receiving time of each beam to obtain a third beam set. And obtaining a second wave beam set according to the third wave beam set and the first preset time length. Optionally, the third beam set may be grouped according to the arrangement order in the third beam set by using the first preset time as a grouping standard, so as to obtain at least one second beam set. For example, when the third beam set includes 10 beams arranged in the order of the receiving time, with respect to the first and second beam sets, the time difference between the receiving time of the first beam and the receiving times of the other 9 beams is determined, the beam with the time difference smaller than or equal to the first preset duration and the first beam are added to the first and second beam sets, and if the first beam set includes 6 beams, determining, for a second set of beams, a time difference between the reception time of a first one of the remaining 4 beams in the third set of beams and the reception time of the other 3 beams, adding the beam having the time difference smaller than or equal to a first preset duration and the first one of the remaining 4 beams to the second set of beams, according to the method described above, until all beams in the third set of beams are allocated into the second set of beams.

Optionally, for the second beam set, if 1 beam remains after the third beam set is grouped, the last beam does not need to be grouped. For example, when the third beam set includes 10 beams arranged according to the receiving time sequence, if 9 beams in the third beam set are divided into 2 second beam sets according to the arrangement sequence in the third beam set and using the first preset time duration as the grouping criterion, the last beam in the third beam set does not need to be grouped.

Next, with reference to fig. 9, a process of grouping the third beam set according to the arrangement order in the third beam set and using the first preset time as a grouping criterion to obtain at least one second beam set is described in detail.

Fig. 9 is a schematic diagram of another process for determining a second beam set according to an embodiment of the present application. Referring to fig. 9, a third beam set a, a third beam set B, a third beam set C, a second beam set a, and a second beam combination B are included. Wherein the third set of beams includes beam 1, beam 2, beam 3, beam 4, and beam 5. Wherein, the difference between the receiving time of the beam 1 and the receiving time of the beam 2 is less than a first preset duration, and the difference between the receiving time of the beam 3, the receiving time of the beam 4, the receiving time of the beam 5 and the receiving time of the beam 1 is greater than the first preset duration. The difference between the receiving time of the beam 3 and the receiving time of the beam 4 is smaller than a first preset duration, and the difference between the receiving time of the beam 5 and the receiving time of the beam 3 is larger than the first preset duration.

Referring to fig. 9, the third beam set a is grouped for the first time by using a first preset duration as a grouping criterion. Since the difference between the reception instant of beam 1 and the reception instant of beam 2 is smaller than the first preset duration, beam 1 and beam 2 are added to the second set of beams a. After the first grouping, a second beam set a and a third beam set B result. The second beam set a includes a beam 1 and a beam 2, and the third beam set B includes a beam 3, a beam 4, and a beam 5.

Referring to fig. 9, the second grouping is performed with the first preset duration as the grouping criterion. Since the first beam in the third beam set B is beam 3, the difference between the receiving time of beam 3 and the receiving time of beam 4 is smaller than the first preset duration, and the difference between the receiving time of beam 5 and the receiving time of beam 3 is larger than the first preset duration, beam 3 and beam 4 are added to the second beam set B. After the second grouping, a second set of beams B and a third set of beams C result. The second beam set B includes a beam 3 and a beam 4, and the third beam set C includes a beam 5. Since there is only one beam 5 in the third beam set C, the third beam set C is not grouped and there is no need to perform interference cancellation processing on the beam 5.

And S804, determining a target beam set in the at least one second beam set.

It should be noted that the execution process of S804 may refer to the execution process of S203, and is not described herein again.

And S805, determining the maximum group number of the terminal equipment for interference elimination.

Optionally, when the terminal device performs interference cancellation, due to the limitation of the hardware processing capability of the terminal device, the terminal device may perform interference cancellation processing on the limited target beam set. For example, if the hardware processing capability of the terminal device can perform interference cancellation processing on beams in 5 target beam sets at most, the number of the target beam sets is less than or equal to 5 when performing the interference cancellation processing.

Optionally, the maximum number of groups for interference cancellation of the terminal device may be determined according to a third preset time duration. The third preset time length may be a maximum time length that the terminal device set by the user can perform interference cancellation. For example, when the terminal device performs interference cancellation, in order to reduce power consumption of the terminal device and a time delay of a signal, a user may set a maximum time duration for performing interference cancellation by the terminal device, and further determine a maximum number of groups for performing interference cancellation by the terminal device according to a time duration required for performing interference cancellation on each group of target beam sets by the terminal device and a third preset time duration. For example, the preset third preset time duration is 10 microseconds, and if the time duration when the terminal device performs interference cancellation on the beams in the set of target beams is 5 microseconds, the maximum number of sets of interference cancellation of the terminal device is 2.

And S806, determining the number of the target beam sets.

Optionally, when determining the target set of beams from the second set of beams, the number of target sets of beams may be determined. For example, the number of the second beam sets is 10, and if each of the second beam sets can be determined as the target beam set, the number of the second beam sets is 10.

And S807, determining a fourth beam set according to the number of the target beam sets and the maximum group number.

The fourth beam set is a beam set which can be subjected to interference cancellation processing by the terminal device. For example, when the terminal device performs the interference cancellation processing on the target beam set, due to the limitation of the hardware processing capability of the terminal device, the terminal device needs to determine a fourth beam set that needs to perform the interference cancellation processing among the multiple target beam sets.

The fourth set of beams may be determined according to the following possible implementations: and if the number of the target beam sets is less than or equal to the maximum group number, determining the target beam set as a fourth beam set. For example, if the number of target beam sets is less than or equal to the maximum number of groups, it indicates that the hardware processing capability of the terminal device may perform interference cancellation processing on beams in all the target beam sets, and therefore, all the target beam sets may be determined as the fourth beam set.

And if the number of the target beam sets is larger than or equal to the maximum group number, acquiring a fourth beam with the strongest signal in each target beam set. For example, if the number of target beam sets is 10 and the number of maximum sets is 5, the beam with the strongest signal in each target beam set is determined as the fourth beam, and the number of the fourth beams is 10. Optionally, each beam in the target beam set may be analyzed to obtain the signal strength of each beam in the target beam set, and then determine the fourth beam with the strongest signal.

And determining a fourth beam set according to the fourth beam and the maximum group number. Optionally, the fourth beam combination may be determined according to the following feasible implementation manners: and determining a target beam set corresponding to the N beams with the strongest signals as a fourth beam set according to the signal intensity of each fourth beam. Wherein N is a positive integer less than or equal to the maximum number of groups. For example, when the maximum number of groups is 5 and the target beam set is 10, determining a fourth beam with the strongest signal in each target beam set, determining 5 fourth beams with the strongest signal strength according to the signal strengths of the 10 fourth beams, and determining 5 target beam sets corresponding to the 5 fourth beams as the fourth beam set. For example, if the maximum number of sets is 2, the signal intensity of the beam a is greater than the signal intensity of the beam B, and the signal intensity of the beam B is greater than the signal intensity of the beam C, the fourth beam set is the target beam set a corresponding to the beam a and the target beam set B corresponding to the beam B.

And S808, carrying out interference elimination processing on the beams in the fourth beam set.

The interference cancellation process may be performed for the beams in the fourth beam set according to the following feasible implementation manners: and determining the maximum number of beams for the terminal equipment to perform interference cancellation in each fourth beam set. For example, the fourth beam combination includes 10 beams, and the maximum number of beams is 5 if the terminal device performs interference cancellation on 5 beams in the fourth beam set. Optionally, the maximum number of beams may be determined according to the hardware processing capability of the terminal device. Optionally, the maximum number of beams may be determined according to a time length for performing interference cancellation on each fourth beam set by the terminal device preset by the user. For example, if the preset time duration for the terminal device to perform interference cancellation on each fourth beam set is 10 nanoseconds, and the time duration for the terminal device to perform interference cancellation on each beam is 2 nanoseconds, the maximum number of beams is 5.

And performing interference elimination processing on the M wave beams with strongest signals in the fourth wave beam set. Wherein M is a positive integer less than or equal to the maximum number of beams. For example, if the fourth beam set includes 10 beams and the maximum number of beams is 5, the terminal device performs interference cancellation processing on the 5 beams with the strongest signals in the fourth beam set. For example, the fourth beam set includes a beam a, a beam B, and a beam C, where the signal intensity of the beam a is greater than that of the beam B, the signal intensity of the beam B is greater than that of the beam C, and if the maximum number of beams for the terminal device to perform interference cancellation on the fourth beam set is 2, the terminal device performs interference cancellation processing on the beam a and the beam B.

Optionally, the terminal device may perform interference cancellation processing on the M beams with the strongest signals in the fourth beam set according to the following feasible implementation manners: reference information for the M beams is acquired. Wherein the reference information is used to indicate an interference cancellation mode supported by the beam. Optionally, the reference information corresponding to different reference signals in the beam is different. For SSB signals in a beam, the reference information of the SSB signals includes the reconstruction information of PBCH and modulo-4 of the physical cell identity. Wherein the reconfiguration information of the PBCH is used to indicate whether the PBCH in the beam can be reconfigured. Modulo 4 of the physical cell identity is the remainder of the physical cell identity divided by 4. For CSIRS signals in a beam, the reference information of the CSIRS signals includes the position of the CSIRS signals in the frequency domain, the offset of the start position of the CSIRS signals, and the number of Resource Blocks (RBs) of traffic channel Resource allocation. Wherein, the position of the CSIRS signal in the frequency domain is used for indicating the position of the frequency segment when the CSIRS signal is transmitted. The initial position of the CSIRS signal is the initial position of the CSIRS signal in the beam. The offset of the CSIRS signal starting position is used to indicate the position deviation between the position of the CSIRS signal and the starting position.

And determining the interference elimination modes of the M beams according to the reference information. For example, for the reference information of the SSB signal, if PBCH of M beams can be reconstructed, the interference cancellation mode of M beams in the fourth beam set is the PBCH interference cancellation mode; if the PBCH of any beam cannot be reconstructed, acquiring the identities of physical cells served by the base station that sends M beams, and if the modulo-4 calculation of the identities of each physical cell is the same, the interference cancellation mode of the M beams in the fourth beam set is a Demodulation Reference signal (DMRS) interference cancellation mode; if the modulo-4 calculation of the identifier of any one physical cell is different from the modulo-4 calculation of the identifiers of other physical cells, the interference cancellation mode of the M beams in the fourth beam set is the interference cancellation mode of the Secondary Synchronization Signal (SSS).

For example, for the reference Information of the CSIRS signals, if the CSIRS signals of the M beams have the same position in the frequency domain, the same offset of the starting position of the CSIRS signals, the same starting position of the CSIRS signals, and the same number of RBs, the interference cancellation mode of the M beams in the fourth beam set is the Channel State Information (CSI) interference cancellation mode; if the positions of the CSIRS signals of the M beams in the frequency domain, the offsets of the starting positions of the CSIRS signals, and the number of RBs are different, the interference cancellation processing is not performed on the M beams in the fourth beam set (in this case, the interference cancellation processing may be performed on the M beams in the fourth beam set, but the time length of the interference cancellation processing is longer, and the power consumption of the system is larger).

And according to the interference elimination mode, carrying out interference elimination on the M wave beams. For example, if the plurality of interference cancellation modes are PBCH interference cancellation modes, then the M beams in the fourth set of beams are interference cancelled according to the PBCH interference cancellation modes.

Optionally, the interference cancellation may be performed on the M beams according to the following feasible implementation manners: and acquiring the interference elimination duration of the fourth beam set, the number of the fifth beams and the processing duration of the terminal equipment for processing the fifth beams. The interference cancellation duration of the fourth beam set may be a duration required by the terminal device to perform interference cancellation on M beams in the fourth beam set. The fifth beam is a beam that does not perform interference cancellation. For example, the fourth beam set includes 10 beams, the terminal device performs interference cancellation on 3 beams in the fourth beam set, and the number of beams that do not perform interference cancellation in the fourth beam set is 7. The processing duration of the terminal device for processing the fifth beam is used for indicating the duration required by the terminal device when the terminal device measures the fifth beam.

And determining the iteration times of interference elimination according to the interference elimination time length, the number of the fourth wave beam sets, the number of the fifth wave beams, the processing time length and a second preset time length. The second preset time length is a preset total time length for the terminal device to perform iteration, and the iteration number may be an iteration processing number for interference cancellation. The number of iterations for interference cancellation can be determined according to the following equation:

J×X+A×K×Y≤T

j is the number of the fifth beams, X is the processing duration of the terminal device for processing the fifth beams, a is the number of iterations, K is the number of the fourth beam set, Y is the duration required by the terminal device for interference cancellation on M beams in the fourth beam set, and T is a second preset duration.

The value of the number of iterations a may be determined according to the above formula, where a is an integer greater than 0, and may be rounded down when calculating the value of a.

The interference cancellation process will be described in detail below with reference to fig. 10.

Fig. 10 is a schematic diagram of an interference cancellation process according to an embodiment of the present application. The embodiment shown in fig. 10 is a process of performing 2 iterations on 4 beams in the fourth set of beams. See fig. 10, including a first iteration and a second iteration. Wherein the first iteration includes beam a, beam B, beam C, and beam D. Since beam a is the first beam at the time of interference cancellation, there is no need to determine the interfering beam. The interference beam of the beam B is the beam A, and the beam B after the first interference elimination is the beam B1; the interference beam of the beam C is a beam A and a beam B1, and the interference beam of the beam C after the first interference elimination is a beam C1; the interfering beams of beam D are beam a, beam B1, and beam C1, and beam D is beam D1 after the first interference cancellation.

Referring to fig. 10, the second iteration includes beam a, beam B1, beam C1, and beam D1. The interference beam of the beam A is the beam B1, the beam C1 and the beam D1, and the beam A after the second interference elimination is the beam A1; the interference beam of the beam B1 is a beam a1, a beam C1 and a beam D1, and the interference beam of the beam B1 after the second interference cancellation is a beam B2; the interference beam of the beam C is a beam a1, a beam B2 and a beam D1, and the beam C1 after the second interference cancellation is a beam C2; the interference beam of beam D1 is beam a1, beam B2, and beam C2, and beam D1 is beam D2 after the second interference cancellation.

The embodiment of the application provides a grouping method for cell interference elimination, which includes determining a first beam set, wherein the first beam set includes a plurality of beams, each beam includes a signal of a preset type, determining a receiving time of each beam in the first beam set, determining a second beam set according to the receiving time of each beam and a first preset duration, determining a target beam set in at least one second beam set, determining a maximum group number of terminal equipment interference elimination, determining the number of the target beam set, determining a fourth beam set according to the number of the target beam set and the maximum group number, and performing interference elimination processing on the beams in the fourth beam set. According to the method, the terminal equipment can quickly and effectively convert the beams in the second beam set into the frequency domain for interference elimination through one-time conversion processing, and performs multi-iteration interference elimination processing on the beams meeting the interference elimination condition, so that the interference elimination duration of the terminal equipment is reduced on the premise of saving the power consumption of the system, and the interference elimination efficiency of the terminal equipment is further improved.

Based on any of the above embodiments, the following describes, by way of example, a procedure of the above grouping method for cell interference cancellation with reference to fig. 11.

Fig. 11 is a process diagram of a grouping method for cell interference cancellation according to an embodiment of the present application. Referring to fig. 11, the first set of beams includes beam 1, beam 2, beam 3, beam 4, and beam 5. The receive time of beam 1 is earlier than the receive time of beam 2, the receive time of beam 2 is earlier than the receive time of beam 3, the receive time of beam 3 is earlier than the receive time of beam 4, and the receive time of beam 4 is earlier than the receive time of beam 5. Wherein, the beam 1, the beam 2, the beam 3, the beam 4 and the beam 5 all include signals of preset types. And sequencing each beam in the first beam set according to the receiving time of each beam in the first beam set to obtain a third beam set. Each beam in the third set of beams is arranged in order of reception time instants.

Referring to fig. 11, a beam 1 is determined as a first start beam, and a beam 4 is determined as a first end beam when a difference between receiving times of the beam 1 and the beam 4 is smaller than a first preset time duration and a difference between receiving times of the beam 1 and the beam 5 is larger than the first preset time duration. Since beam 4 is the first end beam, beam 5 is determined as the second start beam and beam 7 is determined as the second end beam. The third set of beams may be split into a second set of beams a and a second set of beams B according to two start beams and two end beams. Wherein, the second beam set a includes a first start beam: beam 1, first end beam: beam 4, and beams 2 and 3 between beam 1 and beam 4. The second set of beams B includes a second start beam: beam 5, second end beam: beam 7, and beam 6 between beam 5 and beam 7.

Referring to fig. 11, in the second beam set a, since the frequency domain information of the beam 4 does not overlap with the frequency domain information of the beam 1, the beam 2, and the beam 3, a target beam set a may be determined according to the second beam set a, where the target beam set a includes the beam 1, the beam 2, and the beam 3. In the second beam set, the frequency domain information between any two beams is overlapped, and therefore, the second beam set B is determined as a target beam set B, wherein the target beam set B includes a beam 5, a beam 6 and a beam 7.

Referring to fig. 11, the maximum number of groups of the terminal device is 1, and the terminal device performs interference cancellation processing on beams in one target beam set. The beam with the largest signal strength in the target beam set a is beam 1, and the beam with the largest signal strength in the target beam set B is beam 5. Since the signal strength of beam 1 is greater than the signal strength of beam 5, the target beam set a is determined to be the fourth beam set.

Referring to fig. 11, the maximum number of beams for the terminal device to perform interference cancellation on the fourth beam set is 2, and since the signal strength of beam 1 is greater than that of beam 2, and the signal strength of beam 2 is greater than that of beam 3, the terminal device performs iterative interference cancellation processing on beam 1 and beam 2. Because the receiving time difference between any two wave beams in the second wave beam set is less than or equal to the first preset time length, the terminal device can quickly and effectively convert the wave beams in the second wave beam set to the frequency domain for interference elimination, and carry out multi-iteration interference elimination on the wave beams meeting the interference elimination condition, so that the time length for the interference elimination of the terminal device is reduced on the premise of saving the power consumption of the system, and the efficiency for the interference elimination of the terminal device is further improved.

Fig. 12 is a schematic structural diagram of a grouping apparatus for cell interference cancellation according to an embodiment of the present application. The grouping means 10 for cell interference cancellation may be provided in a terminal device. Referring to fig. 12, the grouping apparatus 10 for cell interference cancellation may include a first determining module 11, a grouping module 12, a second determining module 13, and a canceling module 14, where:

the first determining module 11 is configured to determine a first beam set, where the first beam set includes a plurality of beams, and each beam includes a signal of a preset type;

the grouping module 12 is configured to group the beams in the first beam set to obtain at least one second beam set, where a difference between reception times of any two beams in the second beam set is less than or equal to a first preset duration;
