Description

Method and device for transmitting information

Technical Field

The embodiment of the invention relates to the field of communication, in particular to a method and a device for transmitting information.

Background

As a fourth-generation mobile communication technology, a Long Term Evolution (LTE) technology introduces a key technology 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 a subframe, bandwidth, waveform, and the like. The design of the subcarrier spacing needs to be capable of resisting the influence of Doppler frequency shift and phase noise, and the larger the subcarrier spacing is, the better the performance of resisting Doppler frequency shift and phase noise is, and the better the system performance is. The doppler shift is mainly affected by the carrier frequency and the moving speed of the user, and the larger the carrier frequency is, the larger the moving speed is, the larger the doppler shift is. The effect of phase noise on system performance is more pronounced as the carrier frequency increases. In the LTE system, only low frequency services need to be supported, so the influence of doppler shift and phase noise on the system performance is relatively limited, and therefore the requirement on the subcarrier spacing type is limited. For example, in LTE, the subcarrier spacing generally used for downlink traffic is 15kHz, and the theoretical part also supports subcarrier spacing of 7.5kHz, but the subcarrier spacing of 7.5kHz is not well put into practical use, and in current LTE systems, there is no deep research on coexistence between different subcarrier spacings. The setting of the subframe length is mainly influenced by the delay requirement, and the smaller the delay requirement is, the shorter the subframe length is. A shorter subframe length may be achieved by reducing the number of symbols or increasing the subcarrier spacing, thereby reducing the symbol length.

The 5th-Generation (5G) mobile communication technology aims to provide a flexible system which can meet various service requirements, and provides a technical basis for future vertical service and industrial application, including from air interfaces to networks, and the whole network is more flexible and efficient. For example, the carrier frequency range that can be supported by a 5G communication system extends from below 6GHz to 40GHz and even higher, the influence of doppler shift and phase noise generated at different carrier frequencies on the system can be greatly different, and generally, the larger the carrier frequency, the greater the requirement for subcarrier spacing. Therefore, in order to effectively support diversity of services, diversity of scenes, and diversity of frequency spectrums in the 5G communication system, it is proposed to support more subcarrier spacings, for example, the supported subcarrier spacing is 15kHz × N or 15kHz/N, where N is a positive integer. Since a larger system bandwidth is supported in the 5G communication system, in order to effectively utilize the large bandwidth, it is proposed in the 5G technology to support a plurality of services having different delay requirements and reliability requirements through a plurality of sets of parameters on one carrier bandwidth. Multiple sets of parameters on one carrier can coexist in a frequency division multiplexing and/or time division multiplexing manner, so how to effectively coordinate sets of parameters at different subcarrier intervals becomes a problem to be solved urgently.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, shall fall within the scope of protection of the present invention.

Fig. 1 is a diagram of one subframe in an LTE system in the related art. Each subframe comprises a number of symbols, one subframe may be 1ms, and one subframe comprises two slots, each slot being 0.5ms, taking a subcarrier spacing of 15kHz as an example. One slot includes 7 symbols or 6 symbols, each of which includes a cyclic prefix CP and a portion without a CP. According to the difference of CP length, the subframes can be divided into two types: NCP subframes and ECP subframes. Wherein 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 fig. 1. Taking a bandwidth of 20MHz and a sampling rate of 30.72MHz as an example, the length of CP of each symbol in one NCP subframe is not exactly equal, wherein the length of CP in the first symbol of each slot is 160Ts, the length of CP in the remaining symbols is 144Ts, and the length of the part without CP in all symbols is 2048Ts, where Ts represents a 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. Fig. 1 shows an NCP subframe, with long CP of length 160Ts indicated by diagonal lines in the box, short CP of length 144Ts indicated by horizontal lines in the box, and without CP, the 14 symbols in a subframe being numbered in sequence: 0,1, …, 13.

Fig. 2 is a diagram illustrating a design of different subframes corresponding to a multi-subcarrier spacing in the related art 5G technology. In the parameter design in the OFDM-based multi-parameter wireless communication system, in the prior art, the LTE parameter design based on fig. 1 is usually adopted for scaling up or down, as shown in fig. 2.

For the design of the length of the sub-frame for each parameter, one existing approach is to have equal length for each sub-frame. Based on an NCP subframe with a bandwidth of 20MHz and a sampling rate of 30.72MHz, 2 × N long CPs and 12 × N short CPs are contained in 1ms time for a subcarrier interval of 15kHz × N, wherein the length of the long CP is the length of the long CP in the LTE15kHz NCP subframe divided by N, the length of the short CP is the length of the short CP in the LTE15kHz NCP subframe divided by N, and N is a positive integer. For the subcarrier spacing of 15kHz, the subframe length is 0.5ms as an example, each subframe has 7 symbols, wherein the length of the CP of the 1 st symbol is 160Ts, the length of the CP of the rest symbols is 144Ts, and the length of the symbol part without CP is 2048 Ts. For a sub-carrier spacing of 30KHz, taking the sub-frame length of 0.25ms as an example, there are 7 symbols in each sub-frame, where the CP of the first symbol has a length of 80Ts, the CP of the remaining symbols has a length of 72Ts, and the symbol portion without CP has a length of 1024 Ts. That is, in the sub-frame corresponding to different subcarrier intervals, one long CP and 6 short CPs are included in every 7 consecutive symbols.

However, the symbol boundaries between different subcarrier spacings in fig. 2 are not aligned in the time domain. For example, at subcarrier spacing of 15kHz, the boundary of symbol 0 is at (160+2048) Ts. The symbol boundary at which the subcarrier spacing corresponding to the boundary of symbol 0 at 15kHz is 30kHz is the boundary where symbol 0 and symbol 1 are combined, at (80+1024+72+1024) Ts. It can be seen that the corresponding symbol boundaries are not aligned for a subcarrier spacing of 15kHz and a subcarrier spacing of 30 kHz. However, when different subcarrier spacings coexist in a carrier in a frequency division multiplexing manner and are located in the same processing channel, symbol boundary alignment in subframes corresponding to different subcarrier spacings is beneficial to implement processing of symbol level granularity for the whole bandwidth at the symbol boundary. At this time, if the symbol boundaries are not aligned, an additional processing step is required, which may increase processing delay. Meanwhile, when the symbol boundaries corresponding to different subcarrier intervals are not aligned, TDM of symbols of different subcarrier intervals in the time domain is not facilitated.

The following provides a specific scheme of a method for transmitting information and symbol boundary alignment in conjunction with one embodiment of the present invention shown in fig. 3 to fig. 6.

Fig. 3 is a schematic interaction diagram of a method of transferring information in accordance with one embodiment of the present invention. Fig. 3 includes a transmitting end and a receiving end.

101, a transmitting end determines a first time unit and a second time unit which need to carry information. Wherein the first time unit corresponds to a first subcarrier spacing and the second time unit corresponds to a second subcarrier spacing, both the first time unit and the second time unit comprising a symbol portion, and at least one of the first time unit and the second time unit within the first time period comprising at least one non-symbol portion, the position of the non-symbol portion being arranged by the system such that symbol boundaries of the first time unit and the second time unit are aligned.

In one embodiment of the present invention, at least one of the first time unit and the second time unit in the first time period includes at least one non-symbol 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, such that the non-symbol portion of the first time unit and the symbol portion of the second time unit correspond, e.g., the non-symbol portion of the first time unit corresponds to the CP of the second time unit.

In one embodiment of the present invention, when both the first time unit and the second time unit include non-symbol portions, time periods of the non-symbol portions corresponding to different subcarrier intervals may be the same. In other words, when both the first subcarrier interval corresponding to the first time unit and the second subcarrier interval corresponding to the second time unit are greater than or equal to 15kHz, the second time unit corresponding to the second subcarrier interval is also a non-symbol part in the time of the non-symbol part of the first time unit corresponding to the first subcarrier interval, and the second time unit is also a symbol part in the time of the symbol part of the first time unit.

In one embodiment of the invention, when both the first time unit and the second time unit include non-symbol portions, the time periods of the non-symbol portions corresponding to different subcarrier spacings may be different. In other words, when one of a first subcarrier interval corresponding to the first time unit and a second subcarrier interval corresponding to the second time unit is smaller than 15kHz, a second time unit corresponding to the second subcarrier interval is a symbol part and/or a non-symbol part in the time of the non-symbol part of the first time unit corresponding to the first subcarrier interval, and the second time unit is a non-symbol part and/or a symbol part in the time of the symbol part of the first time unit.

In one embodiment of the present invention, the time unit includes a symbol part and a non-symbol part, and the length of the non-symbol part is the same and the length of the symbol part is the same at different subcarrier intervals within the same time duration.

In one embodiment of the invention, the non-symbol part may be configured as a GP or a beam switching time for different transmit directions.

In one embodiment of the present invention, the length of each symbol corresponding to the same subcarrier spacing may be the same. The length of the cyclic prefix CP included in each symbol corresponding to the same subcarrier spacing may be the same or different. Each symbol CP length may be determined by the number of the corresponding symbol, and thus, the length of the CP included in each symbol may be different. In addition, the length of the CP can be further shortened, and the length of the non-symbol portion can be increased.

In one embodiment of the present invention, each symbol includes a corresponding CP, the second subcarrier spacing is N × first subcarrier spacing, the CP length of each symbol in the first time unit corresponding to the first subcarrier spacing is N × CP length of each symbol in the second time unit corresponding to the second subcarrier spacing, or the sum of the CP lengths of the symbols corresponding to the N second subcarrier spacings in the second time unit is equal to the CP length of the symbol corresponding to one first subcarrier spacing in the first time unit. The sum of the lengths of the symbol parts except the CP corresponding to the N second subcarrier intervals in the second time unit is equal to the length of the symbol part except the CP corresponding to one first subcarrier interval in the first time unit. Specifically, the length of the symbol portion excluding the CP of each symbol in the first time unit is N × the length of the symbol portion excluding the CP of each symbol in the second time unit corresponding to the second subcarrier interval.

In the embodiment of the invention, the system defines a set of parameter system for each subcarrier interval, which comprises the length of a time unit, the number range of the time unit, the CP length of a symbol in the time unit and the like. In one embodiment of the present invention, the length of the time unit may be configured by the system according to at least one of a traffic type, a scene type, a subcarrier spacing, a carrier frequency, and a capability of a receiving end. The number range of the time length may also be determined according to at least one of subcarrier spacing, carrier frequency, traffic type. The time unit here may be the first time unit or the second time unit.

In one embodiment of the invention, when the subcarrier spacing is 15kHz N or 15kHz N, the time unit of the first CP type corresponding to the subcarrier spacing comprises a multiple of 7 and/or 2^ p of symbols. The subcarrier spacing is a first subcarrier spacing or a second subcarrier spacing, 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. The first CP type here may be NCP.

In one embodiment of the invention, when the subcarrier spacing is 15kHz N or 15kHz N, the time unit of the second CP type corresponding to the subcarrier spacing comprises a multiple of 3 and/or 2^ p of symbols. The subcarrier spacing is a first subcarrier spacing or a second subcarrier spacing, N is a positive integer, P is an integer, and preferably, P may be an integer greater than or equal to 0 and less than or equal to N + 1. The second CP type here may be ECP.

The time unit in the above embodiment may be a subframe. For example, the first time unit is a subframe corresponding to the first subcarrier interval, and the second time unit is a subframe corresponding to the second subcarrier interval.

102, the sending end carries information on the resources of the first time unit and the second time unit.

103, the sending end sends information carried on the resource to the receiving end.

104, the receiving end determines a first time unit and a second time unit which need to receive information. Wherein the first time unit corresponds to a first subcarrier spacing and the second time unit corresponds to a second subcarrier spacing, both the first time unit and the second time unit comprising a symbol portion, and at least one of the first time unit and the second time unit within the first time period comprising at least one non-symbol portion, the position of the non-symbol portion being arranged by the system such that symbol boundaries of the first time unit and the second time unit are aligned.

In an embodiment of the present invention, the definitions of the parameters and the number of symbols in the first time unit and the second time unit of the receiving end may refer to the description in step 101, and are not described herein again to avoid repetition.

The information is received 105 on the resources of the first time unit and the second time unit.

The following describes a specific symbol alignment method and a symbol alignment diagram thereof according to an embodiment of the present invention with reference to fig. 4 to 6. It should be understood that fig. 4 to 6 are only exemplary illustrations of the symbol alignment of the embodiment of the present invention, and do not limit the scope of the present invention.

Fig. 4 is a schematic diagram of symbol alignment according to an embodiment of the present invention. In the embodiment of the present invention, based on a bandwidth of 20MHz and a sampling rate of 30.72MHz, it is assumed that one subframe corresponding to a subcarrier interval of 15kHz includes 7 symbols. The system can be arranged in different subcarrier intervals, wherein one time section is used for defining the symbol length, and the other time section is used for defining the reserved domain of the non-symbol length. In fig. 4, the reserved field of the non-symbol portion is indicated by a frame with a diagonal line, and the symbol portion is indicated by a frame without a diagonal line.

For example, taking a sampling rate of 30.72MHz as an example, a reserved sample domain of 16Ts (about 0.52us) is defined in every 0.5ms at each subcarrier interval, and as a non-symbol part, channels and/or signals are not mapped to time-frequency resources in this time period, and the rest of the time remains as a symbol part, i.e., channels and/or signals can be mapped to time-frequency resources in the rest of the time. In fig. 4, the length of the diagonal line drawn in the box is about 0.52 us. In an embodiment of the invention, the position of the non-symbol part is set by the system so that the symbol boundaries are aligned in different sub-frames with subcarrier spacing of 15kHz and 30 kHz. For example, the location of the non-symbol portion may be as shown in FIG. 4. In addition, the positions of the non-symbol portions may be aligned as long as symbol boundaries are aligned, as shown in fig. 4, or may not be aligned, for example, a non-symbol portion of 15kHz is placed between a first symbol and a second symbol, so that symbol alignment can be achieved as well. In addition, as long as the symbol boundaries are guaranteed to be opposite, it is not necessary that each subcarrier interval contains a non-symbol part, as shown in fig. 4, a part with oblique lines of 15kHz can be used as a CP part of an adjacent symbol in the figure, and the configuration of the non-symbol part of 30kHz is kept unchanged, so that symbol alignment can be realized similarly. The symbol alignment here can be interpreted in a narrow sense as each symbol boundary of 15kHz is aligned with a symbol boundary of 30kHz, or in a broad sense as each symbol boundary of 15kHz is aligned with a symbol boundary of 30kHz or corresponds to the time of a non-symbol-reserved region of 30 kHz.

In one embodiment of the present invention, the symbol length of the portion of each symbol corresponding to the same subcarrier spacing, which does not include the CP, is the same.

In an embodiment of the present invention, under the same CP type, such as NCP, the CP lengths in each symbol corresponding to the same subcarrier interval in the same subframe may be the same as shown in fig. 4, or may be different.

In one embodiment of the present invention, the length of all CPs within every 0.5ms may be defined as 0, with greater than or equal to 0 non-symbol portions being defined in addition to the symbol portion, such that each symbol no longer includes a CP. For example, 1ms may be 15 symbols without CP and without non-symbol parts.

In one embodiment of the present invention, if each symbol includes a corresponding CP, and the second subcarrier spacing is N × first subcarrier spacing, the CP length of each symbol in the first time unit is N × CP length of each symbol in the second time unit, or described as the sum of CP lengths of 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, the first subcarrier interval is 15kHz, the second subcarrier interval is 30kHz, the first time unit is a subframe of 15kHz, and the second time unit is a subframe of 30kHz, so that the CP length in the subframe of 15kHz is 2 × 30 kHz.

In one embodiment of the present invention, the length of the subframe in different subcarrier intervals may be configured by the system according to at least one of a traffic type, a scene type, a subcarrier interval, a carrier frequency, and a terminal capability. The traffic types may include broadcast traffic, enhanced Mobile broadband (eMBB) traffic, Ultra-Reliable and Low Latency Communications (URLLC) traffic, large connector Type Communications (mtc) traffic, and so on. For the same subcarrier spacing, the length 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 15kHz N or 15kHz/N, the number of symbols included in the NCP subframe corresponding to the subcarrier spacing is a multiple of 7 and/or 2^ p. Wherein 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, when the subcarrier spacing is 30kHz, the number of symbols included in one NCP subframe may be 7. In addition, when the subcarrier spacing is 30kHz, one NCP subframe may include 14 symbols, for example, subframe 0 and subframe 1 at 30kHz in fig. 4 are regarded as one subframe, and subframe 2 and subframe 3 are regarded as another subframe. To avoid confusion, fig. 4 shows a schematic diagram in which only one NCP subframe includes 7 symbols.

If the subcarrier spacing is 15kHz N or 15kHz N, the number of symbols included in the ECP subframe corresponding to the subcarrier spacing is a multiple of 3 and/or 2^ p. Wherein 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.

The specific subcarrier interval used in the embodiment of the present invention for data transmission may be obtained by detecting the subcarrier interval of the synchronization signal, or may be predefined by the system or configured by signaling. For the signaling configuration, the base station may perform the signaling configuration through a high-level signaling or a Media Access Control (MAC) CE (Control Element) or physical layer Control information, or the base station may send the signaling configuration to the user in an Access message during an Access process.

It should be understood that, when there are more than two subcarrier spacings in the system, the method for aligning symbols in two subcarrier spacings according to the embodiment of the present invention may also be referred to align the symbols in multiple subcarrier spacings, so as to simplify the processing of symbol-level granularity in the time division multiplexing and/or frequency division multiplexing of the carriers, and facilitate the multiplexing of different subcarrier spacings in the TDM manner.

In one embodiment of the present invention, there may be one or more non-symbol portions in each time unit including the non-symbol portions. For example, the non-symbol part in each sub-frame of 15kHz in fig. 4(a) is one, and the non-symbol part in each sub-frame including the non-symbol part in 30kHz in fig. 4(b) is composed of two parts.

When both the first subcarrier interval and the second subcarrier interval are greater than or equal to the first value, both the first time unit and the second time unit include a non-symbol portion, and in the time of the non-symbol portion of the first time unit, the second time unit is also a non-symbol portion, and in the time of the symbol portion of the first time unit, the second time unit is also a symbol portion, as shown in fig. 4 (a).

At least one of the first subcarrier interval and the second subcarrier interval is smaller than the second value, both the first time unit and the second time unit include a non-symbol portion, the second time unit is a symbol portion and/or a non-symbol portion within a time of the non-symbol portion of the first time unit, and the second time unit is a symbol portion and/or a non-symbol portion within a time of the symbol portion of the first time unit, as shown in fig. 4 (c).

Another method of symbol alignment is described below in conjunction with fig. 5 and 6. In fig. 5 and 6, it is specified that the long CPs are continuously distributed in a given period of time, and the long CPs in the first subcarrier interval are also long CPs in the second subcarrier interval in the period of the long CPs, and the short CPs in the first subcarrier interval are also short CPs in the second subcarrier interval in the period of the short CPs, so that the symbol alignment can be achieved. In the embodiments of fig. 5 and 6, the symbols including the long CP are indicated by the frame with a diagonal line, and the symbols including the short CP are indicated by the frame without a diagonal line, based on the bandwidth of 20MHz and the sampling rate of 30.72 MHz.

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

Fig. 6 is a schematic diagram of symbol alignment according to yet another embodiment of the present invention. In the embodiment of the present invention, a time unit is a subframe as an example. With a bandwidth of 20MHz and a sampling rate of 30.72MHz as a reference, it is assumed that one sub-frame corresponding to a subcarrier spacing of 15kHz includes 7 symbols and one sub-frame corresponding to a subcarrier spacing of 30kHz includes 14 symbols. In the same subcarrier interval, the time length of each subframe is the same, and the number of each subframe including the long CP and the short CP is also the same. For example, in fig. 6, the symbol lengths of subframe 0 and subframe 1 in 15kHz are both 0.5ms, and each subframe includes 1 long CP and 6 short CPs. The symbol lengths of subframe 0 and subframe 1 are also the same in 30KHZ, and subframe 0 and subframe 1 both include 2 long CPs and 12 short CPs.

Different subcarrier intervals are introduced into the 5G system, in order to meet the coordination of parameters among the different subcarrier intervals, the embodiment of the invention provides a method for transmitting information,

fig. 7 is a schematic interaction diagram of a method of transmitting information according to another embodiment of the present invention. Fig. 7 includes a transmitting end and a receiving end.

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

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

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

In an embodiment of the present invention, the sending end and the receiving end have a mapping relationship between information to be sent and a time unit corresponding to a resource that needs to carry the information, which is pre-agreed, and the sending end may determine specific values of the first number and the second number according to the mapping relationship and the information to be sent.

The sending end may also sequentially number only the time units that need to carry information at one subcarrier interval when the sending end is powered on, for example, sequentially number the time units corresponding to the first subcarrier interval, thereby obtaining the first number of the first time unit, and may determine the second number of the second time unit according to the first number of the first time unit. For example, the system may define the length of the time unit and the number range of the time unit corresponding to different subcarrier intervals, and the transmitting end may determine the second number according to the first number, the length of the first time unit, the length of the second time unit, the number range of the first time unit, and the number range of the second time unit. The numbering range of the time units may be determined by the system according to the corresponding subcarrier spacing, or alternatively, the system according to the corresponding subcarrier spacing and the corresponding carrier frequency. The length of the time unit may be configured by the system according to at least one of the following parameters: traffic type, scene type, subcarrier spacing, carrier frequency, and terminal capabilities. The traffic type may include broadcast traffic, large eMBB traffic, URLLC traffic, mtc traffic, and the like. The scene types may include indoor scenes, urban scenes, suburban scenes, high-speed rail scenes, ultra-large connection scenes, highway scenes, internet of vehicles scenes, internet of things scenes, satellite scenes, and the like.

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

In one embodiment of the present invention, the length of the time unit in different subcarrier intervals is proportional, and the number ranges of the time unit in different subcarrier intervals have a certain relationship. For example, when the second subcarrier spacing is 2 times the first subcarrier spacing, the time unit number of the first subcarrier spacing is i, and the time units corresponding to the second subcarrier spacing in the same time are numbered 2 × i and 2 × i +1, where i is an integer. And when the second subcarrier interval is N times of the first subcarrier interval, the number of the time unit of the first subcarrier interval is i, the number of the time unit corresponding to the second subcarrier interval is from N x i to N x i + N-1, and the maximum value of the number of the time unit corresponding to the second subcarrier interval is obtained by adding 1 to perform modulus. If the carrier is frequency division multiplexing carrier, the first number and the second number can be the same in time domain or numbers corresponding to time units which have overlapped parts in time domain and need to bear information; in the case of a time division multiplexing carrier, the first number and the second number may be numbers corresponding to two different time units in which information needs to be carried in a time domain.

The time unit (e.g., the first time unit or the second time unit) in the embodiment of the present invention may be a radio frame, a subframe, 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 subframe, if the transmitting end is a base station and the receiving end is a terminal device, each subframe may include a first-level subframe or a second-level subframe. The first-level subframe may be used by the base station to schedule the cell-level common information 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 may also be a radio frame or a 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 sending end loads 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 sending end and the receiving end implement synchronization, for example, the receiving end is a terminal device, the sending end is a base station, and before the terminal device accesses the base station, the information to be sent determined in step 202 may include at least one of the first number and the second number, so that the receiving end may know the numbers of the time units at different subcarrier intervals when the two implement synchronization. If the information to be transmitted only includes one of the second numbers in the first numbers, for example, when only the first number is included, the receiving end may determine the second number according to the first number, the length of the first time unit, the length of the second time unit, the number range of the first time unit, and the number range of the second time unit, where both the length of the time unit and the number range of the time unit may be predefined by the system, and for the receiving end, the length of the time unit and the number range of the time unit may also be configured by the transmitting end signaling to the receiving end.

In one embodiment of the invention, when the first subcarrier spacing and the second subcarrier spacing are frequency division multiplexed FDM carriers, the time units of the first subcarrier spacing and the time units of the second subcarrier spacing are respectively and independently numbered in sequence. For example, when the second subcarrier interval is N times the first subcarrier interval, the number of the time unit of the first subcarrier interval is i, and the number of the time unit corresponding to the second subcarrier interval is N × i to N × i + N-1 in the same time, and when N × i to N × i + N-1 exceeds the maximum number value of the time unit corresponding to the second subcarrier interval, a modulo operation is performed on the integer from N × i to N × i + N-1 by adding 1 to the maximum number value of the time unit corresponding to the second subcarrier interval, and the value obtained after the modulo operation is recorded as the number of the time unit corresponding to the second subcarrier interval, where N is a positive integer and i is an integer.

In addition, when the second subcarrier interval is N times the first subcarrier interval, the number of the time unit of the first subcarrier interval is i, and the number of the time unit of different subcarrier intervals may be the same in the same time, for example, the number of the time unit corresponding to the second subcarrier interval may be a value obtained by modulo operation of i by 1 added to the maximum number value of the time unit corresponding to the second subcarrier interval.

In an embodiment of the present invention, when the TDM carrier is time division multiplexed at the first subcarrier spacing and the second subcarrier spacing, the number value of any time unit is obtained by adding 1 to the number value of the immediately preceding time unit adjacent in the time domain and performing modulo (maximum desirable number value +1) on the obtained value.

In one embodiment of the present invention, when the TDM carrier is time division multiplexed by the first subcarrier spacing and the second subcarrier spacing, time units of different subcarrier spacings are individually numbered, and when switching from the first subcarrier spacing to the second subcarrier spacing in the time domain, the number value of the time unit of the current second subcarrier spacing is numbered from M, which may be an arbitrarily-selected initial value, for example, M may be 0.

In one embodiment of the present invention, when time division multiplexing TDM carriers in a first subcarrier interval and a second subcarrier interval, a time unit of the first subcarrier interval and a time unit of the second subcarrier interval are respectively and independently numbered, the second subcarrier interval is N times of the first subcarrier interval, when the current time unit is the time unit corresponding to the first subcarrier interval, a number value of the current time unit is i, when the current time unit is the time unit corresponding to the second subcarrier interval, a number value of the current time unit is a value obtained by performing a modulo operation on an integer value between N i and N i + N-1 to add 1 to a maximum number value of the time unit corresponding to the second subcarrier interval, where i is the number of the time unit corresponding to the first subcarrier interval when the first subcarrier interval exists in the current time period, n is a positive integer. The number value of the current time unit may be a value obtained by adding 1 to the maximum number value of the time unit corresponding to the second subcarrier interval.

The FDM and TDM modes in the embodiment of the present invention may coexist, and there may be not only two but also a plurality of subcarrier intervals.

In an embodiment of the present invention, when the transmitting end transmits information, the transmitting end may control the transmission through a higher layer signaling, a control signaling of the MAC layer CE or the physical layer, and the like.

The relationship between the first number and the second number for different subcarrier spacings may be arranged with reference to the time division multiplexed or frequency division multiplexed carriers described above, and detailed embodiments may refer to the description of fig. 8 below.

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

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

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

204, the receiving end receives 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 receiving end can receive corresponding information on the first number and the second number.

In the embodiment of the present invention, there is no restriction on the front-back time sequence between step 201 executed by the receiving end and step 203 executed by the transmitting end. The receiving end and the transmitting end respectively and independently determine the serial numbers of the time units of different subcarrier intervals.

In the embodiment of the invention, the information transmission of different subcarrier intervals can be realized by determining the serial numbers and the information of the time units on different subcarrier intervals needing to bear the information and bearing the information on the resources of the corresponding time units for sending.

It should be understood that the different subcarrier spacings may either time or frequency multiplex the carrier frequencies. When multiple subcarrier spacings coexist, the multiple subcarrier spacings may include both different subcarrier spacings of a time division multiplexed carrier and different subcarrier spacings of a frequency division multiplexed carrier. Specifically, the determination manner of the number of the time unit in the different subcarrier intervals may refer to the number manner of the different time unit in the two subcarrier intervals.

In the embodiment of the invention, the multi-subcarrier spacing system predefines the time unit corresponding to each subcarrier spacing. The time unit in one embodiment of the present invention may be any unit used to describe time, for example, the time unit here may be a symbol, a time interval, a subframe, or a radio frame. Moreover, for different time units and when TDM carrier frequencies are spaced by different subcarriers, the same numbering manner or different numbering manners may be selected for different subcarrier spacings, which is not limited in this embodiment of the present invention. In addition, the system may also define the time unit of each subcarrier interval, and may define the length of the time unit, the number range of the time unit, the length of the CP in the time unit, and the like.

In one embodiment of the present invention, 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.

The lengths of the time units corresponding to different subcarrier intervals may be the same or different, the number ranges of the time units corresponding to different subcarrier intervals may be the same or different, and the number values of the time units corresponding to different subcarrier intervals within the same time may be the same or different.

The numbering of the corresponding time units over different subcarrier intervals is described in detail below in connection with fig. 8.

Fig. 8 is a number of time units corresponding to different subcarrier spacings according to an embodiment of the present invention. The subcarrier spacing in the embodiment of the present invention is exemplified only by 15kHz and 30 kHz. In the embodiment of the present invention, the lengths of the time units corresponding to different subcarrier intervals may be the same or different, the number ranges of the time units corresponding to different subcarrier intervals may be the same or different, and the number values of the time units corresponding to different subcarrier intervals in the same time may be the same or different.

numbers

0,1,2, … in the figure represent numbers of symbols.

In the embodiment of fig. 8, the radio frame numbers, the subframe numbers, and the symbol numbers corresponding to different subcarrier intervals are given, when the radio frame lengths are the same and the subframe lengths are different. In an embodiment of the present invention, under the same CP type, when subcarrier spacing 2 is equal to N × subcarrier spacing 1, it is assumed that the lengths of radio frames corresponding to each subcarrier spacing in subcarrier spacing 1 and subcarrier spacing 2 defined by the system are the same, the lengths of subframes are the same, and the number of symbols included in a subframe is the same. For the number of the radio frame, when the number of the radio frame 1 is i, the number of the radio frame 2 is i. For the number of an integer number of subframes included in a radio frame, the length of subframe 1 is N × the length of subframe 2, the number of subframes included in the radio frame 2 is N times the number of subframes included in the radio frame 1, the maximum number of subframe 2 is N (maximum number +1 of subframe 1) -1, and the subframe number range corresponding to subcarrier interval 2 is a value obtained by performing a modulo operation on an integer value from N i to N i + N-1, the value being obtained by adding 1 to the maximum number value of the subframe corresponding to the second subcarrier interval. For example, in fig. 8, subcarrier spacing 2 is 30kHz, subcarrier spacing 1 is 15kHz, and

subframe numbers

0 and 1 of 30kHz corresponding to subframe number 0 of 15kHz are provided. The number of the integer symbols included in the subframe is equal to the number of the symbols included in the subframe 1, the number range of the symbols is equal, the length of the symbol 1 is equal to the length of the symbol 2, the number range of the symbols corresponding to the subframe 1 is a value obtained by performing modulo operation on an integer value from N i to N i + N-1, the value being obtained by adding 1 to the maximum number value in the time unit corresponding to the second subcarrier interval.

In order to distinguish different subcarrier spacings in the figure, when different subcarrier spacings TDM are present on the same carrier in fig. 8, the time units with subcarrier spacings of 30kHz are indicated by boxes, the numbers in the boxes indicate the numbers of the time units of 30kHz, the time units with subcarrier spacings of 15kHz are indicated by horizontal lines in the boxes, and the numbers with horizontal lines in the boxes indicate the numbers of the time units of 15 kHz.

When the subcarrier spacing is 15kHz, the CP type of the symbol is NCP, the length of the radio frame is 10ms, each radio frame includes 10 subframes, and the number of the radio frame ranges from 0 to 1023 integers. The number of the radio frame in 15kHz is 0 to 1023, and the corresponding radio frame 0 and radio frame 1023 are shown in detail, while radio frames 1 to 1022 are omitted. Each radio frame in 15kHz consists of 10 subframes, which may be numbered 0 to 9, and the numbering of each subframe in radio frame 0 and radio frame 1023 has been plotted in fig. 8 (a). When the subcarrier spacing is 30kHz, the length of a radio frame is 10ms, each radio frame includes 20 subframes, and the number of the radio frame ranges from 0 to 1023. The radio frame numbers 0 to 1023 in 30kHz have been drawn to illustrate the corresponding radio frame 0 and radio frame 1023, with radio frames 1 to 1022 omitted. Each radio frame at 30kHz consists of 20 subframes, which may be numbered 0 to 19, and the numbering of each subframe in radio frame 0 and radio frame 1023 has been plotted in fig. 8 (a). The number of the radio frames in the same time of 15kHz and 30kHz is the same. In the same time, when the subframe number is i for 15kHz, the subframes for 30kHz are numbered 2 × i and 2 × i + 1.

Fig. 8(b) is a schematic diagram of sub-frames and symbols of 15kHz and 30kHz in this embodiment. Each subframe may contain 7 symbols, numbered 0 to 6, at a subcarrier spacing of 15 kHz. Each subframe may contain 7 symbols, numbered 0 to 6, at a subcarrier spacing of 30 kHz. In the same time, when the subframe number is i for 15kHz, the subframes for 30kHz are numbered 2 × i and 2 × i + 1. In the same time, when the symbol number of 15kHz is i, the subframe number of 30kHz is 2 × i modulo 7 and 2 × i +1 modulo 7.

In fig. 8(c), when 15kHz and 30kHz are FDM on the same carrier, the sub-frames corresponding to different sub-carrier intervals are separately numbered. As shown in fig. 8(c), when the subcarrier interval is 15kHz, the subframes are numbered sequentially by 0,1, … 9; when the subcarrier interval is 30kHz, the subframes are numbered 0,1 and … 19 in sequence according to time sequence. When the second subcarrier interval is N times of the first subcarrier interval, the number of the subframe of the first subcarrier interval is i, and in the same time, the integer of the subframe number corresponding to the second subcarrier interval from N i to N i + N-1 is respectively subjected to modular operation (the maximum number +1 of the subframe corresponding to the second subcarrier interval is acceptable), wherein N is a positive integer.

In fig. 8(d), when 15kHz and 30kHz are FDM on the same carrier, the symbols corresponding to different subcarrier spacings are numbered independently. As shown in fig. 8(d), when the subcarrier spacing is 15kHz, symbols are numbered 0,1, … 6 in sequence; when the subcarrier interval is 30kHz, symbols are numbered 0,1, and … 6 in time series. When the second subcarrier interval is N times of the first subcarrier interval, the number of the symbol of the first subcarrier interval is i, and in the same time, the positive integers of the symbols corresponding to the second subcarrier interval from N i to N i + N-1 are respectively subjected to modulo operation (the maximum number +1 of the symbols corresponding to the second subcarrier interval is acceptable), wherein N is the positive integer.

In fig. 8(e), when 15kHz and 30kHz are TDM on the same carrier, the sub-frames corresponding to different sub-carrier intervals are independently numbered. And the second subcarrier interval is N times the first subcarrier interval, when the current subframe is a subframe corresponding to the first subcarrier interval, the number value of the current subframe is i, and when the current subframe is a subframe corresponding to the second subcarrier interval, the number value of the current subframe is N × i to N × i + N-1, where i is the number of the time unit corresponding to the first subcarrier interval when the first subcarrier interval exists in the current time period. As shown in fig. 8(e), when the subcarrier interval is 15kHz, the subframes are numbered sequentially by 0,1, … 9; when the sub-carrier interval is 30kHz, the sub-frames are numbered 0,1 and … 19 in sequence, no matter whether the sub-frames of the sub-carrier interval are in information transmission in the time domain. As in fig. 8(e), the starting subcarrier spacing is 30kHz, the number of the subframe is 0 and 1 as the number when 30kHz alone exists, then the subcarrier spacing is switched to 15kHz, the number of the subframe is 1 as the number when 15kHz alone exists in the time domain, and when the subcarrier spacing is switched to 30kHz again, the number of the subframe is the same as the number when 30kHz alone exists in the time domain, as shown in fig. 4,5,6,7, and so on.

In fig. 8(f), when 15kHz and 30kHz are TDM on the same carrier, the sub-frames corresponding to different sub-carrier intervals are numbered together, and the number value of any time unit is the sequential accumulation of the number values of the previous time units adjacent in the time domain. For example, in fig. 8(f), when one radio frame includes 10 subframes, the number of the subframes in the time domain is sequentially increased by 1 regardless of the subcarrier spacing, that is, the value obtained after the current subframe number is (the previous subframe number +1) is modulo (the maximum desirable number value of the current subframe +1), where the maximum desirable number value for the 15kHz subframe is 9 and the maximum desirable number value for the 30kHz subframe is 19. As shown in fig. 8(f), the number of the sub-frame is numbered from 0 to 0, and is 0,1,2, and 3 …, respectively, regardless of whether the sub-carrier spacing at the current time is changed.

In fig. 8(g), when 15kHz and 30kHz are TDM on the same carrier, the sub-frames corresponding to different sub-carrier intervals are respectively numbered, and when switching from one sub-carrier interval to another sub-carrier interval in the time domain, the number of the sub-frame of the current another sub-carrier interval is renumbered from the initial value M and sequentially increased by 1. Here, M is taken to be 0. As in fig. 8(g), the starting subcarrier spacing is 30kHz, the number of subframes is 0 and 1 as if 30kHz alone were present, then the subcarrier spacing is switched to 15kHz and the number of subframes is coded again starting with 0.

In fig. 8(h), when 15kHz and 30kHz are TDM on the same carrier, symbols corresponding to different subcarrier spacings are independently numbered. And the second subcarrier interval is N times the first subcarrier interval, when the current subframe is a subframe corresponding to the first subcarrier interval, the symbol number value of the current subframe is i, and when the current subframe is a subframe corresponding to the second subcarrier interval, the symbol number value of the current subframe is N × i (maximum number +1 of symbols corresponding to the second subcarrier interval) modulo (N × i + N-1) modulo (maximum number +1 of symbols corresponding to the second subcarrier interval), where i is the number of the time unit corresponding to the first subcarrier interval when the first subcarrier interval exists in the current time period. As shown in fig. 8(h), when the subcarrier interval is 15kHz, the subframes are numbered sequentially by 0,1, … 6; when the subcarrier interval is 30kHz, the subframes are numbered 0,1 and … 6 in sequence according to time sequence, and whether the subframe with the subcarrier interval is transmitted in time domain or not. As in fig. 8(h), the starting subcarrier spacing is 30kHz, the symbol number is 0 and 1 as the number when 30kHz alone exists, then the subcarrier spacing is switched to 15kHz, the symbol number is 1 as the number when 30kHz alone exists in the time domain, and when the subcarrier spacing is switched to 30kHz again, the symbol number is 4,5,6,0 as shown in the figure, and so on.

In fig. 8(i), when 15kHz and 30kHz are TDM on the same carrier, symbols corresponding to different subcarrier intervals are numbered together, and the number value of any time unit is the number value of the previous time unit adjacent in the time domain plus 1. For example, in fig. 8(i), when a subframe includes 7 symbols, the symbols in the time domain are sequentially incremented regardless of the subcarrier spacing, that is, the current symbol number (the previous symbol number +1) is modulo (the maximum acceptable number value +1 of the symbol in the current subcarrier spacing), where the maximum acceptable number for a 15kHz symbol is 6, and the maximum acceptable number for 30kHz is 6. As in fig. 8(i), symbols are numbered from 0, and are respectively numbered 0,1,2,3, 4,5,6,0,1 … regardless of whether the subcarrier spacing at the current time is changed, and when one subframe includes 7 symbols, symbols may be numbered from 0 to 6, and then from 0 to 6.

In fig. 8(j), when 15kHz and 30kHz are TDM on the same carrier, symbols corresponding to different subcarrier intervals are numbered respectively, and when switching from one subcarrier interval to another subcarrier interval in the time domain, the symbols of the current another subcarrier interval are numbered again starting from 0 and increasing sequentially. As in fig. 8(j), the starting subcarrier spacing is 30kHz, the number of the subframe is 0 and 1 as if 30kHz alone existed, then the subcarrier spacing is switched to 15kHz, and the number of the subframe is coded again starting from 0.

It should be understood that the three numbering schemes of the subframes and the three numbering schemes of the symbols may be arbitrarily combined.

In an embodiment of the present invention, there may be a case where a plurality of subcarrier intervals share one carrier in an FDM or TDM manner, or a case where a plurality of subcarrier intervals share one carrier in a coexistence manner of FDM and TDM. When multiple subcarriers coexist, reference may be made to the case where two subcarriers coexist.

For example, when different subcarrier spacings coexist in FDM and TDM manners, and the plurality of subcarrier spacings in both FDM and TDM manners are the same, the number of time units in the same time may be the same for the same subcarrier spacing. For example, when the simultaneous subcarrier spacing is 15kHz and 30kHz and includes both the FDM scheme of the subcarrier spacing between 15kHz and 30kHz as shown in fig. 8(c) and the TDM scheme of the subcarrier spacing between 15kHz and 30kHz as shown in fig. 8(e), the number value of the subframe in fig. 8(e) is the same as the number value of the subframe in fig. 8(c) on the same subcarrier spacing in the same time domain.

In the embodiment of fig. 8 of the present invention, the number of the sub-frames and/or symbols is given by taking the same length of the wireless frames corresponding to different sub-carrier intervals and the different lengths of the sub-frames as examples. In an embodiment of the present invention, the radio frame lengths corresponding to different subcarrier intervals may be the same or different, and the subframe lengths may be the same or different.

When the lengths of the time units are different, the correspondence between the numbers of the time units in different subcarrier intervals can refer to the correspondence between the subframe numbers or the symbol numbers in different subcarrier intervals in fig. 8.
