Technical field

Embodiments of the present application relate to the field of communications, and more particularly, to a method and apparatus for transmitting information.

Background technique

As a fourth-generation mobile communication technology, Long Term Evolution (LTE) technology introduces key technologies such as Orthogonal Frequency Division Multiplexing (OFDM).

The parameters used in the OFDM-based wireless communication system include subcarrier spacing, Cyclic Prefix (CP) length, subframe length, number of symbols in the subframe, bandwidth, waveform, and the like. Among them, the subcarrier spacing design needs to be able to resist the influence of Doppler shift and phase noise. The larger the subcarrier spacing, the better the performance against Doppler shift and phase noise resistance, and the better the system performance. The Doppler shift is mainly affected by the carrier frequency and the user's moving speed. The larger the carrier frequency, the larger the moving speed, the larger the Doppler shift. The effect of phase noise on system performance is more pronounced as the carrier frequency increases. In LTE systems, only low-frequency services need to be supported, so the influence of Doppler shift and phase noise on system performance is relatively limited, so the demand for sub-carrier spacing types is limited. For example, in LTE, the subcarrier spacing usually used for downlink services is 15 kHz, and the theoretical part also supports subcarrier spacing of 7.5 kHz, but the subcarrier spacing of 7.5 kHz is not well put into practical use, and currently in LTE systems, There is no in-depth study of coexistence between different subcarrier spacings. The setting of the subframe length is mainly affected by the delay requirement, and the smaller the delay requirement, the shorter the subframe length. A shorter subframe length can be obtained by reducing the number of symbols or increasing the subcarrier spacing to reduce the symbol length.

The 5th-Generation (5G) mobile communication technology aims to provide a flexible system that can adapt to various business needs, providing a technical basis for future vertical business and industrial applications, from air interface to network, the entire network will More flexible and efficient. For example, the carrier frequency range that the 5G communication system can support extends from below 6 GHz to 40 GHz or higher. The Doppler shift and the phase noise generated by different carrier frequencies will have great influence on the system. Usually, the carrier The higher the frequency, the greater the need for subcarrier spacing. Therefore, in order to effectively support the diversity of services, the diversity of scenes, and the diversity of spectrum, the 5G communication system proposes to support more subcarrier spacing, such as supporting subcarrier spacing of 15 kHz*N or 15 kHz/N, where N Is a positive integer. In order to effectively utilize the large bandwidth in the 5G communication system, in order to effectively utilize the large bandwidth, the 5G technology proposes to support multiple services with different delay requirements and reliability requirements through multiple sets of parameters on one carrier bandwidth. The multiple sets of parameters on one carrier can coexist in the manner of frequency division multiplexing and/or time division multiplexing. Therefore, how to effectively coordinate the various sets of parameters of different subcarrier intervals becomes an urgent problem to be solved.

detailed description

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

FIG. 1 is a schematic diagram of one subframe in an LTE system in the prior art. Each subframe includes a plurality of symbols. Taking a subcarrier spacing of 15 kHz as an example, one subframe may be 1 ms, and one subframe includes two slots, each slot being 0.5 ms. One slot includes 7 symbols or 6 symbols, and each symbol includes a cyclic prefix CP and a portion without a CP. Subframes can be classified into two types according to the length of the CP: NCP subframes and ECP subframes. One slot in the NCP subframe contains 7 symbols, and one slot in the ECP subframe contains 6 symbols. The NCP subframe is drawn in Figure 1. Taking the 20MHz bandwidth and the sampling rate of 30.72MHz as an example, the CP length of each symbol in an NCP subframe is not exactly equal, and the length of the CP in the first symbol of each slot is 160Ts, and the CP in the remaining symbols. The length is 144Ts, and the length of the part without CP in all symbols is 2048Ts, where Ts represents the sampling time unit. For an ECP subframe, one slot contains 6 symbols, and the CP length of each symbol in one ECP subframe is the same. Figure 1 shows an NCP subframe. The long CP with a length of 160Ts is indicated by a diagonal line in the box. The short CP with a length of 144Ts is indicated by a horizontal line in the frame, and the box without any pad is used to indicate that there is no CP. Partially, and numbering 14 symbols in a sub-frame sequentially: 0, 1, ..., 13.

2 is a schematic diagram of a design of different subframes corresponding to multiple subcarrier spacings in the prior 5G technology. In the prior art, the parameter design in the OFDM-based multi-parameter wireless communication system is generally scaled up or down based on the LTE parameter design in FIG. 1, as shown in FIG. 2 .

For the design of the length of the sub-frame for each parameter, one existing method is equal to each sub-frame. Based on the 20MHz bandwidth and the sampling rate of 30.72MHz, the subcarrier spacing of 15kHz*N includes 2*N long CPs and 12*N short CPs in 1ms, where the length of the long CP is The length of the long CP in the LTE 15 kHz NCP subframe is divided by N, and the length of the short CP is the length of the short CP in the LTE 15 kHz NCP subframe divided by N, N is a positive integer. For the subcarrier spacing of 15 kHz, for example, the sub-frame length is 0.5 ms. There are 7 symbols in each sub-frame. The length of the CP of the first symbol is 160 Ts, and the length of the remaining symbols is 144 Ts. The length of the symbol portion is 2048Ts. For the subcarrier spacing of 30 kHz, for example, the sub-frame length is 0.25 ms. There are 7 symbols in each sub-frame. The length of the CP of the first symbol is 80 Ts, and the length of the CP of the remaining symbols is 72 Ts without CP. The length of the symbol portion is 1024Ts. That is, in a subframe corresponding to different subcarrier spacings, one long CP and six short CPs are included in every seven consecutive symbols.

However, the symbol boundaries between the different subcarrier spacings in Figure 2 are not aligned in the time domain. For example, at a subcarrier spacing of 15 kHz, the boundary of symbol 0 is at (160 + 2048) Ts. The symbol boundary when the subcarrier spacing corresponding to the boundary of the symbol 0 of 15 kHz is 30 kHz is the boundary where the symbol 0 and the symbol 1 are combined, at (80 + 1024 + 72 + 1024) Ts. It can be seen that the corresponding symbol boundaries are not aligned when the subcarrier spacing is 15 kHz and the subcarrier spacing is 30 kHz. However, when different subcarrier spacings coexist in frequency division multiplexing in one carrier and When the same processing channel is located, when the symbol boundaries are aligned in the sub-frames corresponding to different sub-carrier intervals, it is advantageous to implement the processing of the symbol-level granularity of the entire bandwidth at the symbol boundary. At this time, if the symbol boundaries are not aligned, additional processing steps are required, which may increase the processing delay. At the same time, when the symbol boundaries corresponding to different subcarrier intervals are not aligned, symbols that are not conducive to different subcarrier spacing are TDM in the time domain.

The method of transmitting information and the specific scheme of symbol boundary alignment are given below in conjunction with the embodiments of FIGS. 3 to 8.

3 is a schematic interaction diagram of a method of transmitting information according to an embodiment of the present application. Figure 3 includes the transmitting end and the receiving end.

101. The sender determines a first time unit and a second time unit that need to carry information. The first time unit corresponds to the first subcarrier interval, and the second time unit corresponds to the second subcarrier interval. The first time unit and the second time unit both include a symbol portion, and the first time unit in the first time period is At least one of the second time units includes at least one non-symbolic portion, the position of the non-symbolic portion being systematically set such that the symbol boundaries of the first time unit and the second time unit are aligned.

In an embodiment of the present application, at least one of the first time unit and the second time unit in the first duration includes at least one non-symbolic portion. For example, the first time unit may include a non-symbol portion, and the second time unit does not include a non-symbol portion, and the non-symbol portion of the first time unit may be corresponding to the symbol portion of the second time unit, for example, the non-symbol of the first time unit The symbol portion corresponds to the CP of the second time unit.

In an embodiment of the present application, when both the first time unit and the second time unit include a non-symbol portion, the time periods of the non-symbol portions corresponding to different sub-carrier intervals may be the same.

The sum of the lengths of the symbol portions other than the CP corresponding to the N second subcarrier intervals in the second time unit is equal to the length of the symbol portion other than the CP corresponding to one first subcarrier interval in the first time unit. Specifically, the length of the symbol portion other than the CP of each symbol in the first time unit = N * the length of the symbol portion other than the CP of each symbol in the second time unit corresponding to the second subcarrier interval.

In the embodiment of the present application, the system defines a set of parameter systems for each subcarrier spacing, including the length of the time unit, the number range of the time unit, and the CP length of the symbol in the time unit. In an embodiment of the present application, the length of the time unit may be configured by the system according to at least one of a service type, a scene type, a subcarrier spacing, a carrier frequency, and a capability of the receiving end. The number range of the length of time may also be determined according to at least one of a subcarrier spacing, a carrier frequency, and a service type.

To avoid repetition, details are not described herein again.

105. Receive the information on the resources of the first time unit and the second time unit.

The method for aligning specific symbols and the symbol alignment thereof in the embodiment of the present application are described below with reference to FIG. 4 to FIG. It should be understood that FIG. 4 to FIG. 8 are merely illustrative of the symbol alignment of the embodiments of the present application, and do not limit the scope of protection of the present application.

4 to 6 are schematic diagrams of symbol alignment of an embodiment of the present application. In the embodiment of the present application, based on the bandwidth of 20 MHz and the sampling rate of 30.72 MHz, it is assumed that one subframe corresponding to the subcarrier spacing of 15 kHz includes 7 symbols. The system can be set in different subcarrier intervals, given a period of time to define the length of the symbol, given another period of time A reserved field used to define non-symbolic lengths. In FIGS. 4 to 6, the reserved field of the non-symbolic portion is indicated by a slash in the frame, and the symbol portion is represented by a frame without the slash.

For example, with a sampling rate of 30.72 MHz, a reserved sampling domain of 16 Ts (about 0.52 us) is defined every 0.5 ms at each subcarrier interval. As a non-symbolic portion, the channel and/or signal are not mapped to this time. The time-frequency resources within, the remaining time is still part of the symbol, that is, the channel and/or signal can be mapped to the time-frequency resources in the remaining time. In Figures 4 to 6, the length of the diagonal line drawn in the frame is about 0.52 us. In the embodiment of the present application, the position of the non-symbol portion is set by the system such that the symbol boundaries in different subframes with subcarrier spacings of 15 kHz and 30 KHz are aligned. For example, the position of the non-symbolic portion may be as shown in FIGS. 4 to 6. In addition, as long as the symbol boundaries are aligned, the positions of the non-symbol portions can be aligned, as shown in Figures 4 to 6, or they may not be aligned, for example, placing the 15 kHz non-symbolic portion in the first symbol and the second. Between the symbols, you can also achieve symbol alignment. In addition, as long as the symbol boundary is guaranteed, it is not necessary to include a non-symbol portion for each subcarrier interval. As shown in FIG. 4 to FIG. 6, a 15 kHz slashed portion can be used as an adjacent symbol in the figure. In the CP part, the 30 kHz non-symbolic part configuration remains unchanged, so that symbol alignment can also be achieved. Symbol alignment here can be interpreted narrowly as each 15 kHz symbol boundary is aligned with a 30 kHz symbol boundary, or it can be broadly interpreted that each 15 kHz symbol boundary is aligned with a 30 kHz symbol boundary or corresponds to a 30 kHz non-symbol. The time the symbol retains the area.

In an embodiment of the present application, the symbol lengths of the portions excluding the CP in each symbol corresponding to the same subcarrier interval are the same.

In an embodiment of the present application, in the same CP type, such as NCP, the length of the CP in each symbol corresponding to the same subcarrier spacing in the same subframe may be the same as shown in FIG. 4 to FIG. 6 , or may be different. .

In one embodiment of the present application, the length of all CPs per 0.5 ms may be defined as 0, and the non-symbol portions are defined to be greater than or equal to 0 except for the symbol portion, such that each symbol no longer includes a CP. For example, 1ms can be 15 symbols without CP and no non-symbolic parts.

In an embodiment of the present application, if each symbol includes a corresponding CP, and the second subcarrier interval=N* first subcarrier spacing, the CP length of each symbol in the first time unit=N* second The CP length of each symbol in the time unit, or the CP length described as N symbols in the second time unit is equal to the CP length of one symbol in the first time unit. For example, in FIG. 4 or FIG. 5, the first subcarrier spacing is 15 kHz, the second subcarrier spacing is 30 kHz, the first time unit is 15 kHz subframe, the second time unit is 30 kHz subframe, then the 15 kHz subframe. The length of the CP in the subframe where the CP length = 2 * 30 KHz.

In an embodiment of the present application, the length of the subframe in different subcarrier intervals may be obtained by the system according to at least one of a service type, a scenario type, a subcarrier spacing, a carrier frequency, and a terminal capability. Service types may include broadcast services, enhanced mobile broadband (eMBB) services, Ultra-Reliable and Low Latency Communications (URLLC) services, massive machine type communications (mMTC) ) Business, etc. For the same seed carrier interval, the lengths of the high frequency and low frequency subframes may be different, and the length of the subframe may be determined according to the carrier frequency.

If the subcarrier spacing is 15 kHz*N or 15 kHz/N, the number of symbols included in the NCP subframe corresponding to the subcarrier spacing is a multiple of 7 and/or 2^p. Where N is a positive integer and p is an integer. Preferably, P may be an integer greater than or equal to 0 and less than or equal to N. For example, in FIG. 4 or FIG. 5, when the subcarrier spacing is 30 kHz, the number of symbols included in one NCP subframe may be 7. In addition, when the subcarrier spacing is 30 kHz, the number of symbols included in one NCP subframe may also be 14, for example, subframe 0 and subframe 1 of 30 kHz in FIG. 4 or FIG. 5 are used as one subframe. Subframe 2 and subframe 3 are used as another subframe. In order to avoid confusion, only one schematic diagram of an NCP subframe including 7 symbols is shown in FIG. 4 or FIG. 5.

If the subcarrier spacing is 15 kHz*N or 15 kHz/N, the number of symbols included in the ECP subframe corresponding to the subcarrier spacing is a multiple of 3 and/or 2^p. Where N is a positive integer and p is an integer. Preferably, P may be an integer greater than or equal to 0 and less than or equal to N+1.

Which subcarrier spacing is used for data transmission in the embodiment of the present application may be obtained by detecting the subcarrier spacing of the synchronization signal, or may be predefined by the system or configured by signaling. For the signaling configuration, the base station may perform signaling configuration by using a higher layer signaling or a medium access control (MAC) layer control element (Control Element, CE) or physical layer control information, or may be connected by the base station. The process is sent to the user in the message of the access process.

It should be understood that when there are more than two subcarrier spacings in the system, the method of symbol alignment in the two subcarrier spacings in the embodiment of the present application may be referenced so that the symbols of multiple subcarrier spacings are all aligned, which is simplified in time division multiplexing and/or The symbol-level granularity processing is performed when the frequency division multiplexed carriers, which facilitates multiplexing in different TDM modes in different subcarrier spacings.

In an embodiment of the present application, the non-symbol portion in each time unit including the non-symbol portion may be one or plural. For example, the non-symbol portion of each sub-frame of 15 kHz in FIG. 4 is one, and the non-symbol portion in each sub-frame including the non-symbol portion in 30 kHz in FIG. 5 is composed of two parts.

When both the first subcarrier spacing and the second subcarrier spacing are greater than or equal to the first value, the first time unit and the second time unit both include a non-symbolic portion, the time of the non-symmetric portion of the first time unit, and the second The time unit is also a non-symbolic portion, and the second time unit is also a symbol portion within the time period in which the symbol portion of the first time unit is located, as shown in FIG.

At least one of the first subcarrier spacing and the second subcarrier spacing is less than the second value, the first time unit and the second time unit both comprise a non-symbolic portion, the time of the non-symbolic portion of the first time unit, the second The time unit is a symbol portion and/or a non-symbol portion, and the second time unit is a symbol portion and/or a non-symbol portion within the time period in which the symbol portion of the first time unit is located, as shown in FIG.

Another method of symbol alignment will be described below with reference to FIGS. 7 and 8. In FIG. 7 and FIG. 8, it is specified that the long CP is continuously distributed in a given period of time, and the second subcarrier interval in the time period in which the long sub CP of the first subcarrier interval is located is also a long CP, the first sub The second subcarrier spacing in the time period in which the short CP of the carrier interval is located is also a short CP, so that symbol alignment can be achieved. In the embodiment of FIG. 7 and FIG. 8, with a bandwidth of 20 MHz and a sampling rate of 30.72 MHz, a symbol including a long CP is indicated by a slash in the frame, and a symbol of a short CP is represented by a frame without a slash. .

FIG. 7 is a schematic diagram of symbol alignment of another embodiment of the present application. In the embodiment of the present application, the time unit is a subframe as an example for description. With a bandwidth of 20 MHz and a sampling rate of 30.72 MHz, it is assumed that one subframe corresponding to the subcarrier spacing of 15 kHz includes 7 symbols, and one subframe corresponding to the subcarrier spacing of 30 kHz includes 7 symbols. In FIG. 7, on the same subcarrier spacing, each subframe includes the same number of symbols, which are all 7. However, the time length of each subframe may be the same or different, and the length of each subframe including the long CP and the short CP may be the same or different. For example, in FIG. 7, the symbol lengths of subframe 0 and subframe 1 in 15 kHz are both 0.5 ms, and each subframe includes 1 long CP and 6 short CPs. However, the symbol lengths of sub-frame 0 and subframe 1 in 30KHZ are different, and both subframe 0 and subframe 2 include 2 long CPs and 5 short CPs, and subframe 1 and subframe 3 all include 7 short CPs.

FIG. 8 is a schematic diagram of symbol alignment of still another embodiment of the present application. In the embodiment of the present application, the time unit is a subframe. Give an example for explanation. With a bandwidth of 20 MHz and a sampling rate of 30.72 MHz, it is assumed that one subframe corresponding to the subcarrier spacing of 15 kHz includes 7 symbols, and one subframe corresponding to the subcarrier spacing of 30 kHz includes 14 symbols. On the same subcarrier spacing, each subframe has the same length of time, and each subframe includes the same length of the long CP and the short CP. For example, in FIG. 8, the symbol lengths of subframe 0 and subframe 1 in 15 kHz are both 0.5 ms, and each subframe includes 1 long CP and 6 short CPs. The symbol lengths of sub-frame 0 and subframe 1 in 30KHZ are also the same, and both subframe 0 and subframe 1 include 2 long CPs and 12 short CPs.

Different sub-carrier spacings are introduced in the 5G system. In order to meet the coordination of parameters between different sub-carrier intervals, the embodiment of the present application provides a method for transmitting information.

FIG. 9 is a schematic interaction diagram of a method of transmitting information according to another embodiment of the present application. The transmitting end and the receiving end are included in FIG.

201. The transmitting end determines a first number of the first time unit and a second number of the second time unit corresponding to the resource to which the information to be transmitted is mapped.

The transmitting end may determine a first number (eg, number X) of the first time unit and a second number (eg, number Y) of the second time unit corresponding to the resource to which the information to be transmitted is mapped according to a pre-configuration or according to a user capability. The first time unit corresponds to the first subcarrier interval, and the second time unit corresponds to the second subcarrier interval.

Before the step 201, the sender may sequentially number the time units that need to bear the information on different subcarrier intervals according to the time when the sender is powered on, and obtain the number of time units corresponding to different subcarrier intervals at different times, thereby obtaining the number of time units to be sent. The first number of the first time unit and the second number of the second time unit to which the information is mapped.

In an embodiment of the present application, the transmitting end and the receiving end have a mapping relationship between the pre-agreed information to be sent and the time unit corresponding to the resource that needs to carry the information, and the sending end may be based on the mapping relationship and the information to be sent. The specific values of the first number and the second number are determined.

The sending end may also sequentially number the time units that need to bear information on one subcarrier interval, for example, sequentially number the time units corresponding to the first subcarrier spacing, and then obtain the first number of the first time unit. And determining the second number of the second time unit according to the first number of the first time unit. For example, the system may define a length of a time unit corresponding to different subcarrier spacings and a range of time units, and the sending end may be based on the first number, the length of the first time unit, the length of the second time unit, and the number of the first time unit. The number range of the range and the second time unit determines the second number. The number range of the time unit may be determined by the system according to the corresponding subcarrier spacing, or the system is determined according to the corresponding subcarrier spacing and the corresponding carrier frequency. The length of the time unit may be obtained by the system according to at least one of the following parameters: service type, scene type, subcarrier spacing, carrier frequency, and terminal capability. Service types may include broadcast services, large eMBB services, URLLC services, mMTC services, and the like. Scene types may include indoor scenes, urban scenes, suburban scenes, high-speed rail scenes, oversized connection scenarios, highway scenes, car networking scenarios, Internet of Things scenes, satellite scenes, and the like.

The "sequential numbering" mentioned in the embodiment of the present application means that the number is started from an initial value at the time of power-on, for example, starting from 0, the number of the current time unit is equal to the number of the previous time unit plus one, and then the (maximum number possible) The value is +1) obtained after modulo.

In an embodiment of the present application, the length of the time unit on different subcarrier intervals is proportional, and the number range of time units on different subcarrier intervals also has a certain relationship. For example, when the second subcarrier spacing is twice the interval of the first subcarrier, the time unit of the first subcarrier interval is numbered i, and the time unit corresponding to the second subcarrier spacing is 2* in the same time. i, 2*i+1, where i is an integer. When the second subcarrier spacing is N times the first subcarrier spacing The time unit of the first subcarrier spacing is numbered i, and the time unit corresponding to the second subcarrier spacing is numbered from N*i to N*i+N-1 to the time unit corresponding to the second subcarrier spacing. The maximum value is obtained by adding 1 to the mode. If it is a frequency division multiplexed carrier, the first number and the second number may be numbers corresponding to time units in the time domain or having coincident parts in the time domain corresponding to time units; if time division multiplexed carriers, then first The number and the second number may be numbers corresponding to two time units that need to carry information in the time domain.

The time unit (for example, the first time unit or the second time unit) in the embodiment of the present application may be a radio frame, a sub-frame, or a symbol. Each radio frame may include at least one subframe, and each subframe may include at least one symbol.

When the time unit is a sub-frame, if the transmitting end is a base station and the receiving end is a terminal device, each sub-frame may include a first-level sub-frame or a second-level sub-frame. The first level subframe may be used by the base station to schedule the common information of the cell level sent to the terminal device, and the second level subframe is used by the base station to schedule the user level information sent to the terminal device. For example, the first level subframe is a cell level subframe, and the second level subframe is a user level subframe.

The time unit can also be a wireless frame or symbol. Similarly, each radio frame may include a first level radio frame and a second level radio frame, and each symbol may include a first level symbol and a second level symbol. The first level radio frame may be a cell level radio frame, the second level radio frame may be a user level radio frame, the first level symbol may be a cell level symbol, and the second level symbol may be a user level symbol.

202. The sender carries the information on the resources of the time unit corresponding to the first number and the second number, and sends the information to the receiving end.

Before the synchronization is performed on the transmitting end and the receiving end, for example, the receiving end is a terminal device, and the transmitting end is a base station. Before the terminal device accesses the base station, the information to be sent determined in step 202 may include the first number and the second number. At least one of them, so that the receiving end can know the number of time units on different subcarrier intervals when the two are synchronized. If the information to be sent includes only one of the second number in the first number, if the first number is included, the receiving end may be based on the first number, the length of the first time unit, the length of the second time unit, and the first time. The number range of the unit and the number range of the second time unit determine the second number, wherein the length of the time unit and the number range of the time unit can be predefined by the system. For the receiving end, the length and time unit of the time unit The range of the number may also be that the sender configures signaling by sending signaling to the receiver.

In an embodiment of the present application, when the first subcarrier interval and the second subcarrier interval are frequency division multiplexed FDM carriers, the time unit of the first subcarrier interval and the time unit of the second subcarrier interval are respectively independently Numbering. For example, when the second subcarrier spacing is N times the first subcarrier spacing, the time unit of the first subcarrier spacing is numbered i, and the time unit corresponding to the second subcarrier spacing is N* in the same time. i to N*i+N-1, and when N*i to N*i+N-1 exceeds the maximum desirable number of time units corresponding to the second subcarrier spacing, for N*i to N*i+ The integer of N-1 performs a modulo operation on the maximum obtainable number value of the time unit corresponding to the second subcarrier interval plus the value obtained by the modulo operation, and the value obtained after the modulo operation is recorded as the time unit corresponding to the second subcarrier interval. Number, where N is a positive integer and i is an integer.

In addition, when the second subcarrier spacing is N times of the first subcarrier spacing, the time unit of the first subcarrier spacing is numbered i, and the time unit numbers of different subcarrier spacings may be the same in the same time, for example, The number of time units corresponding to the two subcarrier spacings may also be a modulo-calculated value of i obtained by adding a maximum value of the time unit corresponding to the second subcarrier spacing plus one.

In an embodiment of the present application, the first subcarrier interval and the second subcarrier interval time division multiplexing TDM In the case of wave time, the number value of any time unit is obtained by adding 1 to the number value of the previous time unit adjacent to the time domain and performing the modulo (the maximum possible number value value +1).

In an embodiment of the present application, when the first subcarrier interval and the second subcarrier interval are time division multiplexed TDM carriers, time units of different subcarrier intervals are separately numbered, and the current subcarrier interval is switched from the first subcarrier interval to In the second subcarrier interval, the number value of the time unit of the current second subcarrier interval is numbered from M, and M may be an arbitrary initial value. For example, M may be 0.

In an embodiment of the present application, when the first subcarrier interval and the second subcarrier interval are time division multiplexed TDM carriers, the time unit of the first subcarrier interval and the time unit of the second subcarrier interval are independently numbered. The second subcarrier spacing is N times of the first subcarrier spacing. When the current time unit is the time unit corresponding to the first subcarrier spacing, the current time unit number is i, and the current time unit is the second subcarrier spacing corresponding. In the time unit, the number value of the current time unit is respectively obtained by adding the maximum number value of the time unit corresponding to the second subcarrier interval to the integer value between N*i and N*i+N-1. The value of the modulo operation of the value, where i is the number of the time unit corresponding to the first subcarrier spacing when the first subcarrier interval exists in the current time period, and N is a positive integer. In addition, the number value of the current time unit may be a modulo-calculated value obtained by adding 1 to the maximum obtainable number value of the time unit corresponding to the second sub-carrier interval.

The FDM and TDM modes in the embodiment of the present application may coexist, and there may be two or more subcarrier spacings.

In an embodiment of the present application, when sending information, the transmitting end may control transmission by using high layer signaling, MAC layer CE, or physical layer control signaling.

For different subcarrier spacings, the relationship between the first number and the second number may refer to the time division multiplexing or frequency division multiplexing carrier setting described above. For detailed embodiments, reference may be made to the descriptions of FIG. 10 to FIG. 19 below.

203. The receiving end determines a first number of the first time unit and a second number of the second time unit corresponding to the resource to which the information to be received is mapped.

The receiving end may determine, according to a pre-configuration or according to the information sent by the received sending end, a first number (for example, number X) and a second number of the second time unit corresponding to the resource corresponding to the resource to which the information to be transmitted is mapped ( For example, number Y). The first time unit corresponds to the first subcarrier interval, and the second time unit corresponds to the second subcarrier interval.

Before receiving the information, the receiving end also needs to determine the first number of the first time unit of the bearer information and the second number of the second time unit, that is, determine the number of at least one current time unit. In other words, if different subcarriers are frequency division multiplexed carriers, the receiving end may determine the current first time unit number and the current second time unit number; if different subcarriers are time division multiplexed carriers, the receiving end may The number of one of the first time unit and the second time unit is determined. For example, the receiving end may determine the number of the first time unit, and may determine the second time unit in the time domain different from the first time unit according to the relationship between the subcarrier spacing, the length of the time unit, the number range of the time unit, and the like. The number.

204. The receiving end receives the corresponding information on the resource of the corresponding time unit according to the first number and the second number determined in step 203.

After the receiving end determines the first number and the second number in step 203, the corresponding information can be received on the first number and the second number.

There is no chronological limitation between the step 201 performed by the receiving end and the step 203 performed by the transmitting end in the embodiment of the present application. The receiving end and the transmitting end independently determine the number of time units of different subcarrier spacings.

In the embodiment of the present application, by determining the number and information of the time unit on different subcarrier intervals that need to carry information, and transmitting the information on the resources of the corresponding time unit, the information transmission of different subcarrier intervals can be implemented.

It should be understood that different subcarrier spacings may be time division multiplexed carrier frequencies, or frequency division multiplexed carriers. When multiple subcarrier intervals coexist, it may include different subcarrier spacings of time division multiplexed carriers and different subcarrier spacings of frequency division multiplexed carriers. For the manner of determining the number of time units on different subcarrier intervals, reference may be made to the numbering manner of different time units in the interval between the two subcarriers.

In the embodiment of the present application, the multi-subcarrier spacing system pre-defines a time unit corresponding to each sub-carrier interval. The time unit in an embodiment of the present application may be any unit for describing the time. For example, the time unit may be a symbol, may be a time interval, may be a subframe, or may be a radio frame. In addition, for different time units, different subcarrier spacing TDM carrier frequencies, different subcarrier spacings may be selected in the same numbering manner, or different numbering manners may be selected, which is not limited in this embodiment of the present application. In addition, the system can also define the time unit of each subcarrier interval, and can define the length of the time unit, the number range of the time unit, and the length of the CP in the time unit.

In an embodiment of the present application, when the time unit is a radio frame, each radio frame may include at least one subframe, and each subframe or time interval includes at least one symbol.
