The present application relates to the field of communications technologies, and in particular, to a communication method, apparatus, device, and system.

Background technique

Limited to the number of available frequency points, there are scenes in which the same working frequency point is configured for a plurality of adjacent cells. For example, in the field of wireless communication operating at unlicensed frequency points, the base station can deploy the same working frequency point for neighboring cells when the available frequency points are small.

In the prior art, when the same frequency point is configured for a plurality of adjacent cells, in order to avoid the influence of the same-frequency interference between the multiple cells on the downlink data received by the user equipment, the following manner is generally adopted: Before using a certain frequency to send a signal, it is first monitored whether the frequency is occupied, and when it is determined that the frequency is not occupied, the downlink is sent through the frequency.

However, in the prior art, the method of monitoring and resending first has a complicated processing problem, and since the network and the user equipment cannot predict whether the frequency point is occupied, the continuous data or the merging of signals cannot be performed, and the number of merges is limited. , affecting coverage issues.

Summary of the invention

The embodiment of the present invention provides a communication method, device, device, and system, which are used to solve the problem of first monitoring and resending in the prior art, and have complicated processing problems, and because the network and the user equipment cannot predict whether the frequency point is occupied, Consolidation of continuous data or signals is not possible, resulting in limited number of merges, affecting coverage issues.

In a first aspect, an embodiment of the present application provides a communication method, including:

The communication device determines a target time domain transmission unit of the target cell operating frequency point; the working frequency point includes a first working frequency point, and the target time domain transmission unit of the first working frequency point is used for downlink public transmission, and the target The neighboring cell adjacent to the cell is configured with the first working frequency point, and the time domain location of the target time domain transmission unit of the target cell and the first working frequency point of the neighboring cell is different;

The communication device performs downlink transmission by using a target time domain transmission unit of the working frequency point of the target cell.

In the foregoing solution, the time domain location of the target time domain transmission unit of the first working frequency point of the target cell and the neighboring cell adjacent to the target cell is different, and the target time domain transmission unit of the first working frequency point is used. In the downlink common transmission, when the working frequency of the target cell and the neighboring cell for the downlink common transmission is the same, the target cell and the first working frequency of the neighboring cell are specifically used for downlink public transmission. The time domain location of the target time domain transmission unit is different, thereby avoiding the problem that the same frequency interference is large when the target cell and the neighboring cell simultaneously perform downlink common transmission, which simplifies the processing process compared with the transmission after the first monitoring. Moreover, the user equipment is enabled to combine all consecutive downlink common signals or data according to the target time domain transmission unit, thereby avoiding the limitation of the number of merges, affecting the coverage problem, and increasing the coverage.

It should be noted that the target time domain transmission unit of the target cell and the first working frequency point of the neighboring cell adjacent to the target cell may also be used to transmit user signals and/or user data. That is, when the target time domain transmission unit of the first working frequency point is not occupied by the downlink common signal and/or data, the target time domain transmission unit may be used to transmit user signals and/or user data. And when the target time domain transmission unit of the first working frequency point is used to transmit user signals and/or user data, and similarly, when the target cell and a neighboring cell adjacent to the target cell have a first working frequency point When the target time domain transmission unit is configured to transmit user signals and/or user data, the time domain locations of the target time domain transmission units of the target cell and the first working frequency point of the neighboring cell adjacent to the target cell are also different.

In a possible implementation, the working frequency further includes: a second working frequency point, where the target time domain transmission unit of the second working frequency point is used for downlink user transmission, adjacent to the target cell.

The downlink user transmission is performed, so that the second working frequency point of the target cell and the neighboring cell is specifically used for downlink user transmission, even if the working frequency of the target cell and the neighboring cell for the downlink user transmission is the same. The time domain location of the target time domain transmission unit is different, which avoids the co-channel interference caused by the downlink cell transmission between the target cell and the neighboring cell, thereby further reducing the co-channel interference.

It should be noted that the time domain location of the target time domain transmission unit of the second working frequency point may be determined by the target time domain transmission unit time domain location of the first working frequency point.

Optionally, since inter-cell interference usually exists between physically adjacent cells, a neighboring cell adjacent to the target cell may be understood as a cell physically adjacent to the target cell. For example, as shown in FIG. 3, a cell adjacent to cell 1 may include cell 2 and cell 3. A cell adjacent to cell 3 may include cell 1, cell 2, and cell 4.

Moreover, the user equipment is enabled to combine all consecutive downlink common signals or data according to the target time domain transmission unit, thereby avoiding the limitation of the number of merges, affecting the coverage problem, and increasing the coverage.

It should be noted that the number of the second working frequency points of the target cell may be zero, one or more, which is not limited in this application. When the number of the second working frequency points is multiple, the target time domain transmission positions of the second working frequency point of the target cell may be the same or different.

Optionally, the first working frequency point of the target cell and the time domain location of the target time domain transmission unit of the second working frequency point are different, and the multiple second jobs of the target cell are different. The time domain location of the target time domain transmission unit of the frequency point is different.

Here, the first working frequency point of the target cell and the time domain location of the target time domain transmission unit of the second working frequency point are different, and the multiple second working frequency points of the target cell The target time domain transmission unit has different time domain positions, and can ensure that the downlink transmission can be performed at the maximum transmission power when performing downlink transmission at each configuration frequency point, and does not require multiple frequency points to equally divide power in the frequency domain. For example, the downlink is configured with three working frequency points, frequency point 1, frequency point 2 and frequency point 3. The frequency point 1 is the first working frequency point for transmitting public signals and/or public data. Both frequency point 2 and frequency point 3 are the second working frequency points. Therefore, the target time domain transmission units of frequency point 1, frequency point 2 and frequency point 3 are different in the time domain, and the frequency point 1 and frequency can be guaranteed. When the downlink transmission is performed at point 2 and frequency 3, the transmission can be performed at the maximum transmission power.

It should be noted that, if the number of reserved time domain transmission units for downlink transmission is less than the first working frequency of the target cell plus the number of the second working frequency, The first working frequency point of the target cell and the time domain location of the target time domain transmission unit of the second working frequency point are different, and the target of the multiple second working frequency points of the target cell The time domain locations of the time domain transmission units may be partially identical or all the same.

The first working frequency point is frequency point 1, the second working frequency point is frequency point 2, the target cell is cell 1, the neighboring cell of cell 1 is cell 2 and cell 3, and cell 1, cell 2 and cell 3 are both For example, the frequency point 1 and the frequency point 2 are configured, and the time domain locations of the target time domain transmission units of the cell 1 and the cell 1 of the cell 1 and the cell 3 are different, and the frequency 2 of the cell 1 and the cell 2 and the cell 3 are different. The time domain location of the target time domain transmission unit is different, as shown in Figure 5. In Figure 5, a rectangular box may represent a time domain transmission unit, and a shadow-filled rectangular box may represent a target time domain transmission unit.

It should be noted that, in FIG. 5, the target time domain transmission unit of each cell frequency point 1 appears cyclically, and the cycle period is the same. For example, the target time domain transmission unit of each cell frequency point 1 may also not appear cyclically, or may appear cyclically. However, the cycle period may be different, which is not limited in this application. In FIG. 5, the boundary alignment of the time domain transmission units of the cell 1, the cell 2, and the cell 3 is taken as an example, and the boundaries of the time domain transmission units of the cell 1, the cell 2, and the cell 3 may not be aligned, which is not limited in this application. .

In the embodiment of the present application, the time domain location of the target time domain transmission unit of the second working frequency point of the target cell and the neighboring cell adjacent to the target cell is different, and the target time domain transmission unit of the second working frequency point is different. For downlink user transmission, when the working frequency of the target cell and the neighboring cell for the downlink user transmission is the same, the second working frequency of the target cell and the neighboring cell is specifically used for downlink user transmission. The time domain location of the target time domain transmission unit is different, which avoids the co-channel interference caused by the downlink cell transmission of the target cell and the neighboring cell at the same time, thereby further reducing the co-channel interference.

Optionally, when the working frequency of the target cell is multiple, downlink common transmission may be performed only at one of the multiple frequency points, for example, performing PSS, SSS, PBCH, and SIB on one frequency point. transmission. The advantage of this is that when the frequency of the target cell changes, different values of the frequency points can be adapted. That is, when the number of frequency points is increased, downlink user transmission may be performed only at the increased frequency, for example, but not limited to, transmission of the PDCCH and the PDSCH channel.

Optionally, each of the network device and the user equipment may determine a target time domain transmission unit of the working frequency point of the target cell. For example, the network device and the user equipment may determine the target time domain transmission unit of the first working frequency point of the target cell according to the cell identifier of the target cell. Alternatively, the target time domain transmission unit of the first working frequency point of the target cell may be determined by the network device, and the target time domain transmission unit of the first working frequency point of the target cell is indicated to the user equipment.

Optionally, a time domain location of the target time domain transmission unit of the first working frequency point of the target cell is related to a cell identity of the target cell. That is, the time domain location of the target time domain transmission unit of the working frequency point of the target cell may be determined according to the cell identity of the target cell. For example, according to different cell identifiers, the time domain location of the target time domain transmission unit of the determined working frequency point is different; or, according to the cell identifier that satisfies the same condition, the time domain location of the target time domain transmission unit of the determined working frequency point is determined. The same, and according to the cell identifiers satisfying different conditions, the time domain location of the target time domain transmission unit of the determined working frequency point is different.

Optionally, when the communications device is a network device, the method further includes:

Optionally, when the communications device is a user equipment, the communications device determines a target time domain transmission unit of the working frequency of the target cell, and specifically includes:

Optionally, the indication information may include at least one of the following: an offset between the target time domain transmission unit and a preset time domain transmission unit, an index of the target time domain transmission unit, and a preset. The number of time domain transmission units reserved for downlink transmission and the number of working frequency points of the target cell reserved in the time length.

Optionally, the offset amount may be an integer. For example, as shown in FIG. 6, assuming that the time domain position of the preset time domain unit is time period 1 and the offset amount is 2, it may indicate that the time domain position of the target time domain transmission unit is time period 3. For another example, if the time domain position of the preset time domain unit is time period 0 and the offset amount is 0, it may indicate that the time domain position of the target time domain transmission unit is time period 0. For another example, if the time domain position of the preset time domain unit is time period 3 and the offset amount is -1, it may indicate that the time domain position of the target time domain transmission unit is time period 2.

Optionally, the time period and the index may be in one-to-one correspondence. For example, the time period 1 may correspond to the index 1, the time period 2 may correspond to the index 2, the time period 3 may correspond to the index 3, and the time period 4 may correspond to the index 4, ..., the time period 15 may Corresponding to index 15. Or, in the same time period, the time period and the index may be in one-to-one correspondence, and the indexes are the same in different time periods, for example, the time period 1, the time period 6, and the time period 11 may correspond to the index 1, and the time period 2, the time period 7, and the time period 12 may correspond to the index 2, the time period. 3. The time period 8 and the time period 13 may correspond to the index 3, and the time period 4, the time period 9, and the time period 14 may correspond to the index 4, and the time period 5, the time period 10, and the time period 15 may correspond to the index 5.

Optionally, when the time domain transmission unit is a subframe, the index may be a subframe number.

Optionally, the preset time length may be greater than or equal to a time length of multiple time domain transmission units. For example, the time length of the time domain transmission unit is 1 ms, and the preset time length may be equal to the length of 10 time domain transmission units, that is, 10 ms.

Optionally, the number of time domain transmission units reserved for downlink transmission within a preset time length may be one or more. Optionally, the time domain transmission unit for performing uplink transmission may also be included in the reserved time length.

It should be noted that the number of the target time domain transmission units in the preset time length may be one or more, which is not limited in this application. Optionally, if the target time domain transmission unit is included in the preset time length, and the network device indicates the target time domain transmission unit of the first working frequency point to the user equipment, the network device may only indicate multiple to the user equipment. A target time domain transmission unit (for example, a time domain transmission unit with the highest time domain location) in the target time domain transmission unit, the user equipment may determine other target time domain transmission units according to the target time domain transmission unit.

In the embodiment of the present application, the number of time domain transmission units reserved for downlink transmission reserved in the preset time length is indicated by the network device to the user equipment, and the user equipment reserves the time domain transmission unit for downlink transmission. The other time domain transmission units except the target time domain transmission unit may neither transmit nor receive, thereby avoiding interference between uplink and downlink transmissions of different network devices or different user equipments, such as interference of adjacent user equipments. In addition, the number of the working frequency points of the target cell is indicated by the network device to the user equipment, and the user equipment may perform downlink signal/data reception on one or more target time domain transmission units.

Optionally, the indication information may be bitmap information.

Further, the bitmap information includes a number of time domain transmission units reserved for downlink transmission within a preset time length, and bit values corresponding to the target time domain transmission unit in the bitmap information. For the first bit value, the bit value of the corresponding location of the target time domain transmission unit is not the second bit value. Optionally, the bit length of the bitmap information may be equal to the number of time domain transmission units reserved for downlink transmission within a preset time length. Optionally, the first bit value may be 1, and the second bit value may be 0.

For example, the bitmap information shown in FIG. 7 may indicate that the number of time domain transmission units reserved for downlink transmission within a preset time length is 3, and reserved for downlink transmission within a preset time length. Among the three time domain transmission units of the time domain transmission unit, the time-first transmission unit with the highest time is the target time domain transmission unit, and the other two time domain transmission units are the non-target time domain transmission units.

In the embodiment of the present application, the bitmap information includes the number of time domain transmission units reserved for downlink transmission within a preset time length, and the time domain for downlink transmission for non-reserved in the bitmap information is avoided. The representation of the transmission unit reduces the bit overhead of the bitmap information.

Further, in order to improve the power spectral density, when the number of working frequency points of the target cell is multiple, the time domain locations of the target time domain transmission units of different working frequency points may be ensured as different as possible.

Optionally, it is assumed that the number of time domain transmission units for downlink transmission reserved in the preset time length is M1, and the number of the working frequency points of the target cell is N1, when N1 is greater than 1 and less than Or equal to the positive integer of M1, the target time domain transmission units of each of the N1 working frequency points do not overlap in the time domain. Assuming that both M1 and N1 are equal to 3, and the three operating frequencies are frequency point 1, frequency point 2, and frequency point 3, respectively, the target time domain transmission units of the three frequency points may be, for example, as shown in FIG. 8A. In FIG. 8A and FIG. 8B described below, a rectangular frame may represent a time domain transmission unit, and a shadow-filled rectangular frame may represent a target time domain transmission unit.

Optionally, when N1 is a positive integer greater than 1 and greater than M1, the target time domain transmission units of the M1 working frequency points of the N1 working frequency points do not overlap in the time domain, and the M1 The working frequency point includes the first working frequency point; (N1-M1) the respective target time domain transmission units of the working frequency points overlap in the time domain. Assuming that M1 is equal to 3 and N1 is equal to 4, and the four operating frequencies are frequency point 1, frequency point 2, frequency point 3, and frequency point 4, respectively, the target time domain transmission units of the four frequency points may be, for example, as shown in FIG. 8B. .

Further optionally, if the number of reserved time domain transmission units for performing downlink transmission is less than the first working frequency point of the target cell plus the number of the second working frequency points, the target The first working frequency point of the cell is different from the time domain location of the target time domain transmission unit of the second working frequency point, and the target time domain transmission unit of the multiple second working frequency points of the target cell The time domain locations may be partially identical or all the same. As shown in FIG. 8B, the frequency point 1 can be used as the first working frequency point, and the frequency point 2 - frequency point 4 can be used as the second working frequency point, and the target of the frequency point 1 and the frequency point 2, the frequency point 3, and the frequency point 4 The time domain locations of the domain transmission units are different. The time domain locations of the target time domain transmission units of

frequency points

3 and 4 are the same, and the time domain locations of the target time domain transmission units of

frequency points

2 and 3 are different.

Further optionally, the target time domain transmission unit of the second working frequency point may be determined according to the target time domain transmission unit of the first working frequency point. For example, as shown in FIG. 8A, it is assumed that the frequency point 1 is the first working frequency point, the frequency point 2, and the frequency point 3 are the second working frequency points, and the index of the target time domain transmission unit of the first working frequency point is 1, It can be determined that the index of the target time domain transmission unit of the frequency point 2 is 1+1=2, and the index of the target time domain transmission unit of the frequency point 3 can be determined to be 1+2=3.

Optionally, the number of target time domain transmission units in the M2 time domain transmission units in the time domain of the same working frequency point is N2, M2 is an integer greater than 1, and M2 is a preset multiple of N2. Optionally, in the consecutive M2 time domain units, the M21 time domain transmission units may be reserved time-domain transmission units for downlink transmission, and the M21 time domain transmission units may include target time domain transmission. Units, M22 time domain transmission units can be used for uplink transmission, and M21+M22 can be less than or equal to M2. In the embodiment of the present application, the M2 is a preset multiple of N2, and the preset multiple is assumed to be K, so that the duty cycle (DC) of the downlink transmission is not greater than (1/k)%, thereby satisfying the wireless communication system. For duty cycle requirements. In systems with duty cycle limitations, there is a limit to the length of time that can be sent over a period of time at the same operating frequency. For example, if the required duty cycle is 10%, then within 1 hour (3600 seconds) ) The duration for sending cannot exceed 360 seconds.

Optionally, the preset multiple is 10 times. In the embodiment of the present application, by setting the multiple of 10 times, it can be ensured that the duty ratio of the downlink transmission is not more than 10%, so that the requirement for the duty ratio under the unlicensed communication system can be satisfied.

Hereinafter, the time domain transmission unit is a subframe, one radio frame includes 10 subframes, and the communication system requires a duty ratio of not more than 10% as an example, and is exemplified by the following example 1 and example 2.

Example 1

In FIG. 9A, the frequency of operation of the cell 1 includes only the frequency point 1, and "0" - "19" indicate the radio frame number. There may be only one downlink subframe in a radio frame for transmitting PSS, SSS, PBCH, SIB, PDCCH or PDSCH, etc. A rectangular frame may represent one subframe.

As shown in FIG. 9A, the single transmission duration of PSS, SSS, PBCH, and SIB is 1 ms under the 10% duty ratio requirement, and the transmission periods are 40 ms, 160 ms, 80 ms, and 160 ms, respectively, that is, PSS, SSS, and PBCH. The downlink overhead of the SIB and the SIB is 5%, which is less than the 10% duty cycle requirement. Therefore, 5% of the resources can be transmitted by the user.

In each radio frame, a downlink subframe that is not occupied by a PSS, SSS, PBCH, or SIB may be used to transmit a PDCCH or a PDSCH. Other subframes may be uplink subframes.

In FIG. 9A, since the cell 1 default subframe 0 and only the subframe 0 can be the downlink subframe actually used for downlink transmission (ie, the target time domain transmission unit), if the neighbor cell of the cell 1 is also in the subframe 0 For downlink transmission, the user equipment (for example, for user equipment at the cell boundary) can simultaneously receive downlink signals and/or data from two cells, which is susceptible to interference. Therefore, the target cell transmission unit of the neighboring cell may be offset with respect to the subframe 0, and the subframe that the neighboring cell actually uses for downlink transmission may be obtained, and the specific description is as follows:

Further, assuming that the cell 1 has two neighboring cells, which are respectively recorded as the cell 2 and the cell 3, the downlink subframe actually used for the downlink transmission in the three cell radio frames may be as shown in FIG. 9B. A rectangular frame in FIG. 9B may represent one subframe, and a shadow-filled rectangular frame may represent a downlink subframe actually used for downlink transmission, and a rectangular frame identified by U may represent an uplink subframe that can be used for uplink transmission, and the first three subframes. It can be used to represent a reserved subframe for downlink transmission. It can be seen that although the operating frequencies of the three cells are the same, the downlink transmissions are staggered in time, so that the same-frequency interference can be effectively avoided.

Optionally, on the basis of the example 1, when the working frequency of the cell is multiple, the PSS, the SSS, the PBCH, and the SIB may be transmitted at only one frequency point. The advantage of this is that the design can adapt to different channel count values as the number of channels changes.

That is, when the number of channels is increased, downlink user data information is transmitted only on the added channel, including but not limited to the PDCCH and the PDSCH channel.

Example 2

On the basis of the example 1, when the working frequency of the cell is multiple, it is assumed that the transmission of PSS, SSS, PBCH, and SIB is performed only at one frequency point.

As shown in FIG. 10A, when the working frequency of the cell 1 includes the frequency point 1, the frequency point 2, and the

frequency point

3, 3 frequency points, for the frequency point 1, the cell 1 performs downlink on the subframe 0 of the frequency point 1. When transmitting, downlink transmission is not performed on subframe 0 of frequency point 2 and frequency point 3; for frequency point 2, when cell 1 performs downlink transmission on subframe 1 of frequency point 2, it is not at frequency point 1 and frequency point 3 Downlink transmission is performed on subframe 1; for frequency point 3, when cell 1 performs downlink transmission in subframe 3 of frequency point 3, downlink transmission is not performed in subframe 3 of frequency point 1 and frequency point 2. Thus, the downlink subframes of each frequency point can also be staggered in time.

When there is a limit on the total transmission power of the network device, the fewer the number of frequency points transmitted at the same time, the larger the power spectrum, the better the service of the remote user equipment and the reduction of the signal power caused by the deep fading of the link. Therefore, when the downlink resources are not limited, even if the base station can transmit at different frequency points, the transmission can be staggered in time to avoid a decrease in power spectral density.

It should be noted that the subframe corresponding to “no transmission” in FIG. 10A can be understood as not using the subframe for transmission.

Further, assuming that the cell 1 has two neighboring cells, which are respectively recorded as the cell 2 and the cell 3, the downlink subframe actually used for the downlink transmission in the three cell radio frames may be as shown in FIG. 10B to FIG. 10D. 10B-10D, for frequency point 1, cell 1 performs downlink transmission on subframe 0, cell 2 performs downlink transmission on subframe 2, and cell 3 performs downlink transmission on subframe 1: for frequency point 2, Cell 1 performs downlink transmission on subframe 1, cell 2 performs downlink transmission on subframe 0, and cell 3 performs downlink transmission on subframe 2; for frequency point 3, cell 1 performs downlink transmission on subframe 2, the cell 2 downlink transmission is performed on subframe 1, and cell 3 performs downlink transmission on subframe 0. In this way, the same frequency point is offset by time to avoid co-channel interference, and different frequency points of the same cell are also staggered in time, thereby avoiding a decrease in power spectral density.

Further, on the basis of FIG. 10B to FIG. 10D, when the number of frequency points is more than the reserved number of subframes for downlink transmission, for example, when three cells add frequency point 4, three cell radio frames are used. The downlink subframe actually used for downlink transmission may be as shown in FIGS. 10E-10G.

It should be noted that a rectangular frame in FIG. 10B-10G may represent one subframe, and a shadow-filled rectangular frame may represent a downlink subframe actually used for downlink transmission, and a rectangular frame marked by U may indicate that it may be used for uplink transmission. For the uplink subframe, the first 3 subframes may be used to indicate the reserved subframe for downlink transmission, and "0"-"9" indicates the subframe number.

Step 202: The communication device performs downlink transmission by using a target time domain transmission unit of the working frequency point of the target cell.

In this step, when the communication device is a network device, the step 202 may include: the network device may determine a target time domain transmission unit of the target cell working frequency point, and pass the working frequency point of the target cell. The target time domain transmission unit performs downlink transmission. When the communication device is a user equipment, the step 202 may include: the user equipment may determine a target time domain transmission unit of the target cell working frequency point, and pass the target time domain of the working frequency point of the target cell. The transmission unit performs downlink reception.

Specifically, the foregoing first working frequency point may include: performing downlink common transmission by using a target time domain transmission unit of the first working frequency point of the target cell. Optionally, the downlink public signal and/or the downlink common data may be sent by the target time domain transmission unit of the first working frequency point of the target cell.

Optionally, when the working frequency point includes the second working frequency point, the method further includes: performing downlink user transmission by using a target time domain transmission unit of the first working frequency point of the target cell. Optionally, the downlink user signal and/or the downlink user data may be sent by the target time domain transmission unit of the first working frequency point of the target cell.
