That is, it is multiplexed after the time slot (being designated as previous time slot) that the OFDM symbol of N KHz subcarrier spacings is formed with M KHz During the time slot that the OFDM symbol at carrier wave interval is formed (or the time slot that group carrier wave is formed at intervals of N OFDM symbol is (before being designated as One time slot) after be multiplexed a sub- carrier wave at intervals of M OFDM symbol when), previous time slot may increased symbolic number be： It is less thanPositive integer,Expression rounds downwards.N is more than or more than or equal to M.

It is described in detail below by multiple specific embodiments.

Embodiment one

With reference to figure 5, when a variety of different SCS time slot (in a dispatching cycle) time division multiplexing, every kind of SCS time slot is pressed The starting point for being used as time slot according to the OFDM symbol placement location in each comfortable dispatching cycle carries out timeslot multiplex.

Or the time slot (being designated as previous time slot) that group carrier wave is formed at intervals of N OFDM symbol is multiplexed one afterwards During time slot (being designated as the latter time slot) that the OFDM symbol that subcarrier spacing is M is formed (or group carrier wave is at intervals of N OFDM When OFDM symbol (being designated as the latter symbol) that subcarrier spacing is M is multiplexed after the time slot that symbol is formed), the latter time slot The starting position of (or the latter symbol) should be one that the OFDM symbol that subcarrier spacing is M is sequentially placed within dispatching cycle The starting position of individual OFDM symbol, the starting position is before and the duration after previous time slot can be regarded as an independent resource, should Independent resource is not calculated in previous time slot.Wherein, N is more than or more than or equal to M.

For example, the time slot time division multiplexing that subcarrier spacing (SCS) is 15KHz time slot and SCS is 30KHz, now SCS be 30KHz time slot since the border of dispatching cycle, according to SCS be OFDM symbol duration corresponding to 30KHz scheduling week Order is placed in phase, and 7 symbols (it is assumed here that 7 OFDM symbols are a time slot) are used as a time slot before interception.Base afterwards Stand want send SCS be 15KHz time slot, then base station according to OFDM symbol corresponding to 15KHz SCS within dispatching cycle it is suitable Sequence is placed, and intercepts 7 complete symbols after previous time slot as time slot corresponding to 15KHz SCS.Now, although SCS is OFDM symbol corresponding to 30KHz SCS is wasted between the time slot that 30KHz time slot and SCS is 15KHz, but this side Formula is simple, it is easy to accomplish more symbol aligneds (being alignd with the OFDM symbol at reference subcarrier interval), avoids interference.

For other SCS (such as 3.75KHz, 7.5KHz, 15KHz, 30KHz, 60KHz, 75KHz, 120KHz, 240KHz, When time slot 480KHz) is time-multiplexed, principle is identical, is repeated no more here.

Embodiment two

With reference to figure 6, the OFDM symbol that embodiment one wastes increased to compared to embodiment one, in the present embodiment previous In time slot, i.e., the OFDM symbol number increase of previous time slot.Base station can dynamically indicate the symbol quantity of time slot.

Or the timeslot multiplex mode in the present embodiment can be described as：During different SCS time slot time division multiplexing, when two Individual time slot according to respective OFDM symbol duration given dispatching cycle order place when, if between two time slots exist not by The duration used, the duration is turned into OFDM symbol according to the SCS of previous time slot, calculated in the previous time slot.

Or the timeslot multiplex mode in the present embodiment can be described as：Group carrier wave is formed at intervals of N OFDM symbol Time slot (being designated as previous time slot) after be multiplexed a sub- carrier wave at intervals of M OFDM symbol form time slot (be designated as latter Individual time slot) when (or group carrier wave is multiplexed the OFDM that subcarrier spacing is M afterwards at intervals of the time slot that N OFDM symbol is formed During symbol (being designated as the latter symbol)), the end position of previous time slot be subcarrier spacing be M OFDM symbol to setting the tone The starting position of the OFDM symbol that order is placed in the cycle is spent, or, the beginning of the latter time slot (or the latter symbol) Position is the starting position for the OFDM symbol that the OFDM symbol that subcarrier spacing is M is sequentially placed within dispatching cycle, should Duration before starting position all be can be regarded as in previous time slot.Wherein, N is more than or more than or equal to M.

For example, the time slot time division multiplexing that the time slot and SCS that SCS is 15KHz are 30KHz, now SCS is 30KHz's Time slot is that OFDM symbol duration corresponding to 30KHz is sequentially put within dispatching cycle according to SCS since the border of dispatching cycle Put, 8 symbol (it is assumed here that the time slot of standard is 7 OFDM symbols, this time slot now is 8 symbols) conducts before interception One time slot.Base station is wanted to send the time slot that SCS is 15KHz afterwards, then base station accords with according to OFDM corresponding to 15KHz SCS Number sequentially placed within dispatching cycle, when intercepting 7 complete symbols after previous time slot as corresponding to 15KHz SCS Gap.Now, the part more than 7 OFDM symbols for the time slot that SCS is 30KHz is the time slot that SCS is 30KHz and SCS is 15KHz Time slot between duration form, this mode will not waste of resource, but the OFDM symbol number that time slot includes is to become It is changing, it is necessary to which base station passes through symbolic number or stop bits that signaling is that terminal (UE, User Equipment) indicates that the time slot includes Put.

Embodiment three

With reference to figure 7, one is multiplexed after the time slot (being designated as previous time slot) that group carrier wave is formed at intervals of N OFDM symbol During time slot (being designated as the latter time slot) that individual sub- carrier wave is formed at intervals of M OFDM symbol (or group carrier wave is at intervals of N's When OFDM symbol (being designated as the latter symbol) that subcarrier spacing is M is multiplexed after the time slot that OFDM symbol is formed), when previous Starting position of the end position of gap as next time slot (or the latter symbol), carry out time slot time division multiplexing.Wherein, N is not Equal to M.

For example, the time slot time division multiplexing that the time slot and SCS that SCS is 15KHz are 30KHz, now SCS is 30KHz's Time slot is that OFDM symbol duration corresponding to 30KHz is sequentially put within dispatching cycle according to SCS since the border of dispatching cycle Put, 7 symbols (it is assumed here that 7 OFDM symbols are a time slot) are used as a time slot before interception.Base station is wanted to send afterwards SCS is 15KHz time slot, then base station accords with since the end position of previous time slot according to OFDM corresponding to 15KHz SCS Number sequentially placed within dispatching cycle, when intercepting 7 complete symbols after previous time slot as corresponding to 15KHz SCS Gap.Now, will not waste of resource, but many symbols of the latter time slot without and reference subcarrier interval OFDM symbol pair Together.

Example IV

Assuming that base station configures a reference subcarrier interval, the reference subcarrier is at intervals of 15KHz, it is assumed that reference subcarrier Subframe corresponding to interval includes 14 OFDM symbols, and (first symbol is slightly longer due to there is longer CP, other symbols length Spend equal), time slot includes 7 OFDM symbols.

For other subcarrier spacings, such as when subcarrier spacing is 30KHz, time slot corresponding to the subcarrier spacing includes Symbol quantity can be：H×2^kIndividual OFDM symbol.Wherein, H be reference subcarrier interval generation OFDM symbol form when The symbol quantity of gap.K meets that current sub-carrier interval is the 2 of reference subcarrier interval^kTimes.So, it is assumed that between reference subcarrier 7 symbols are included every corresponding time slot, then include 7 × 2 using time slot corresponding to 30KHz subcarrier spacings^k(k=1) individual symbol Number (this symbol is 30KHz subcarrier spacings).

Based on above-mentioned thinking and it is assumed that improved Slot symbol number is configurable to multiple possible values, these take Value meets 7 × 2^k, now k maximum occurrences meet that current sub-carrier interval is the 2 of reference subcarrier interval^kTimes.K causes 7 × 2^k Value is integer.In this case, the symbolic number of time slot can be multiple values, and base station is configured as needed.This Kind improved procedure can be equal to following description：Under current sub-carrier interval, time slot corresponding to the current subcarrier spacing Symbol quantity be one in following：H×2^k, wherein, H is the time slot that the OFDM symbol of reference subcarrier interval generation is formed Symbolic number.B meets that current sub-carrier interval is the 2 of reference subcarrier interval^bTimes.K span and b span phase Together, when b takes the value less than or equal to b to timing, k in the span.

Base station can configure (reference subcarrier that the UE of i.e. same cell configure of the reference subcarrier at intervals of cell level It is spaced identical), or UE ranks (UE of same cell can configure the reference subcarrier interval of different (or part is identical)), or (the reference subcarrier interval of the UE configurations in same wave beam is identical) of person's wave beam rank.

Embodiment five

For other subcarrier spacings, such as the symbolic number that includes of time slot that subcarrier spacing is 30KHz is：Y×2^kIt is individual OFDM symbol.Wherein, Y is positive integer, and Y value is configured by base station or is about set to fixed value in advance.K meets between current sub-carrier Every being the 2 of reference subcarrier interval^kTimes.In this way, include Y × 2 using the time slot of 30KHz subcarrier spacings^k(k=1) individual symbol (this symbol is 30KHz subcarrier spacings).If base station configuration Y value includes 8 for the time slot of 4,30KHz subcarrier spacings Individual symbol.In this case, the symbolic number of time slot can be multiple values, and base station is configured as needed, when being easy to Gap is alignd with the OFDM symbol at reference subcarrier interval.

Embodiment six

For other subcarrier spacings, such as the symbolic number that includes of time slot that subcarrier spacing is 30KHz is：Y × L OFDM symbol.Wherein, Y is positive integer, and Y value is configured by base station or is about set to fixed value in advance.L meets between current sub-carrier Every being L times of reference subcarrier interval.In this way, include individual symbol (this of Y × L (L=2) using the time slot of 30KHz subcarrier spacings Symbol is 30KHz subcarrier spacings).If base station configuration Y value includes for time slot corresponding to 4,30KHz subcarrier spacings 8 symbols.In this case, the symbolic number of time slot can be multiple values, and base station is configured as needed, when being easy to Gap OFDM symbol corresponding with reference subcarrier interval is alignd.

Embodiment seven

It is assumed that base station and terminal (UE) agreement base station can configure the symbolic number of time slot, if the Slot symbol that UE is received Several signalings is space-time, then UE determines the symbolic number of time slot according to the Slot symbol number arranged with base station or given tacit consent to, and carries out The reception or transmission of data.If UE receives the signaling of Slot symbol number, UE according to base station treaty rule, calculate time slot Symbolic number.The rule specifically arranged is referred to described in example IV, five and six, therefore is repeated no more in this.

Embodiment eight

In order to adapt to the transmission of low time delay, high reliability, paroxysmal URLLC business, the symbolic number that time slot includes is defined For 2 or 4.Typically in order to meet low time delay requirement, it is transmitted using larger subcarrier spacing, is greater than or is equal to 60KHz subcarrier spacing.

In 5G system, because multiple business demand coexists, the time slot of multiple subcarrier spacings is necessarily caused to coexist, this When, the problem of how being multiplexed these time slots be present.

In 15KHz time slot, such as include 7 15KHz SCS symbol, some symbols are made in this timeslot During with being transmitted for the bigger business of other subcarrier spacings (such as 60KHz SCS), now, time slot corresponding to other SCS includes Symbolic number be 2, then now can be in 15KHz SCS correspond to time slot by 1 15KHz or 2 (or integer individual) 15KHz OFDM symbol, switch to time slot corresponding to the OFDM symbol at other carrier wave intervals.

For example, 1 15KHz OFDM symbol is switched into 1 time slot, wherein, the time slot has corresponding to 4 60KHz SCS OFDM symbol.Or, 1 15KHz OFDM symbol is switched to the time slot of 2 cascades, wherein, each time slot has 2 60KHz OFDM symbol corresponding to SCS.

In another example 2 15KHz OFDM symbol is switched into 2 time slots, time slot can be cascade, wherein, when this is each Gap has OFDM symbol corresponding to 4 60KHz SCS.Or, 2 15KHz OFDM symbol is switched into 4 time slots, time slot can be Cascade, wherein, each time slot has OFDM symbol corresponding to 2 60KHz SCS.

So during nested or overlapping multiplexing, it is easy to snap to 60KHz SCS time slot for 15KHz SCS time slot 15KHz SCS character boundary, so as to reduce interference.

In above-mentioned example, base station should configure, symbolic number G that time slot corresponding to other subcarrier spacings includes meet with Lower condition：The OFDM symbol at one reference subcarrier interval can be split as G (for example, G is 2,4,8 ... 2ⁿIn one, n For integer) OFDM symbols of complete other subcarrier spacings, or including G (for example, G is 2,4,8 ... 2ⁿIn one, n For integer) OFDM symbol at complete reference subcarrier interval can be polymerized to the OFDM symbol of other subcarrier spacings. So, can be snapped to after time slot corresponding to other subcarrier spacings, or the cascade of other multiple subcarrier spacing time domains OFDM symbol border corresponding to one reference subcarrier interval, or the border of time slot corresponding to reference subcarrier interval, Huo Zhecan Examine the border of subframe corresponding to subcarrier spacing.

The mode of this definition is easy to, when the time slot or symbol at different sub-carrier interval carry out time multiplexed transmission, hold The OFDM symbol alignment at different sub-carrier interval is easily realized, so as to reduce interference.
