Description

Communication means and communicator
Technical field
The present invention relates to communication technical field, in particular to a kind of communication means and a kind of communicator.
Background technology
Existing 4G and 4.5G mobile communication technology, (Long Term Evolution, drills for a long time to be all based on LTE Enter) and the wireless access technology of LTE-A (LTE-Advanced), running time-frequency resource granularity and frame structure etc..LTE system such as at present The maximum a width of 20MHz of single carrier band that can support, to support bigger bandwidth, can only rely on carrier aggregation (Carrier Aggregation, be called for short CA) use.It addition, current frame structure specifically includes that FDD (Frequency Division Duplexing, FDD) frame structure, TDD (Time Division Duplexing, time division duplex) frame structure and LAA The dynamic frame structure that (LTE Assisted Access, LTE assist access) unauthorized carrier wave uses.Regardless of frame structure, All comprising 10 subframes, each subframe is 1ms, and each subframe comprises two slot (time slot), and a slot is 0.5ms, each Slot comprises again 7 symbol (symbol).Frequency domain aspect, in LTE system, subcarrier spacing is mainly 15KHz, a RB (Resource Block, Resource Block) contains 12 subcarriers.And at NB-IoT (Narrow Band Internet of Things, protenchyma based on honeycomb is networked) in the subcarrier spacing of a kind of new 3.75KHz proposed again, and NB-IoT Carrier bandwidths only has 180KHz.
In terms of resource distribution, FDD frame structure and tdd frame structure be all with 1ms subframe for time domain scheduling granularity, except DwPTS (Downlink Pilot Time Slot, descending pilot frequency time slot) in special subframe in tdd frame structure is used for transmitting During data, time domain scheduling granularity be less than 1ms's.Also multiplexing is occurred in that equally in the frame structure that the unauthorized carrier wave of LAA uses DwPTS, as the descending scheduling time domain granularity of partial subframe, also using the scheduling granularity of the whole subframe of 1ms simultaneously. And in FDD frame structure and tdd frame structure, except the existing down sending time of the special subframe in tdd frame structure and up Send outside the time, other subframe be all up transmission or descending transmission time domain separately otherwise frequency domain separately.
Visible, current frame structure and the granularity of frequency domain resource all can make resource distribute underaction, and uplink scheduling Mechanism makes again time delay relatively big with the time interval of HARQ feedback mechanism etc., and 20MHz bandwidth is also unsatisfactory for high bandwidth requirements.

In this technical scheme, by adding identification information in the system information generated, communication system can be used New sub-frame configuration is identified.Specifically, can be identified by the form of IE.
Visible, technical scheme be primarily directed at present fixing frame structure, fixing frequency domain resource granularity and Time-domain resource granularity can cause bigger uplink scheduling time delay and longer HARQ feedback time delay, and less carrier bandwidths is also The technical problem of the diversified demand of business cannot be met, it is proposed that a kind of technical scheme being applicable to 5G communication scenes, specifically Including following aspects:
One, the frame structure that 5G NR (New Radio, new wireless technology) uses.
The frame structure that 5G NR is used can use dynamic frame structure, specifically: below the subframe acquiescence in radio frames Row subframe starts, and sub-frame of uplink is determined by DCI dispatch by base station and triggers.Wherein, the subframe in radio frames Acquiescence starts with descending sub frame, and descending sub frame here both can be one or more complete descending sub frame, it is also possible to be only In part in one complete descending sub frame, i.e. certain subframe, only first half is for downlink transfer.
On this basis, it is also possible to the subframe that a part periodically occurs is semi-statically configured into sub-frame of uplink, on these Row subframe is used for sending uplink reference signals SRS (i.e. Sounding Reference Signal, Sounding Reference Signal) And/or uplink scheduling request (i.e. Scheduling Request) and/or buffer status report (i.e. Buffer Status And/or random access lead code etc. Report).
Additionally, for uniform authorization frequency spectrum and unlicensed spectrum, for above-mentioned uplink reference signals SRS and/or up Dispatch request and/or buffer status report and/or random access lead code etc., have one to send window, Mei Gefa in each cycle Send window to comprise repeatedly and send the time, as long as sending once within any one transmission time.
Two, for paired bandwidth, the present invention proposes the following two kinds using method:
1, paired bandwidth is used together.
Specifically, with the paired bandwidth in multiplexing tradition LTE FDD system, or the new band used in pairs can be configured Wide.Wherein, the size of paired bandwidth is the same, but frequency is different.
Illustrate as a example by paired bandwidth in multiplexing tradition LTE FDD system below:
Owing to one section of bandwidth of the paired band alleviating distention in middle-JIAO of tradition LTE FDD system is served only for descending (referred to as LTE_DL_BW), One section of bandwidth is served only for up (referred to as LTE_UL_BW).Paired bandwidth in NR, in multiplexing tradition LTE FDD system Time, it is traditionally used for descending bandwidth and may be used for downlink and uplink, be traditionally used for up bandwidth and can be used for up With descending.But there is priority when resource is distributed, be only not enough to being traditionally used for descending bandwidth (i.e. LTE_DL_BW) When providing downlink transfer, just scheduling is traditionally used for up bandwidth (i.e. LTE_UL_BW) as downlink transfer.Equally, only When being traditionally used for up bandwidth (i.e. LTE_UL_BW) and being not enough to provide uplink, just scheduling is traditionally used for descending Bandwidth (i.e. LTE_DL_BW) be used as uplink.
During additionally, bandwidth uses in pairs together, these two sections of bandwidth LTE_DL_BW and LTE_UL_BW can be configured to The mode that two independent non-paired carrier waves carry out carrier aggregation to use to user.And under traditional descending carrier is configured to The PCell (Primary Cell main plot) of row, is configured to up PCell by traditional up-link carrier, will up-downgoing divide From.
2, paired bandwidth uses not together.
When paired bandwidth uses not together, can paired bandwidth be completely independent comes gives different user's uses, The most each user is only able to detect the uplink carrier frequencies of paired band alleviating distention in middle-JIAO or descending carrier frequency simultaneously, then user is just being operated in this Community on individual carrier frequency uses as the up-downgoing carrier frequency on this carrier frequency, is i.e. similar to the mode of existing TDD.
Three, for above-mentioned paired bandwidth, the indicating mode of its bandwidth is as follows:
1, when paired bandwidth is used together, be equivalent to give each bandwidth of paired band alleviating distention in middle-JIAO one cell (community) Using, using as LTE_DL_BW given cell#1, LTE_UL_BW is given cell#2 and uses, and the cell# of LTE_DL_BW 1 is descending PCell, then cell#1 indicates the value of LTE_DL_BW by the MIB in system information.And the LTE_ of cell#2 UL_BW is up PCell, then cell#2's is descending as SCell (Secondary Cell, secondary cell), now cell# The bandwidth value of 2 can be sent by descending PCell i.e. cell#1 by RRC signaling.
2, when paired bandwidth independently uses, LTE_DL_BW and LTE_UL_BW is respectively the up-downgoing of different cell, So the two cell indicates the bandwidth of self respectively by the mib information of self.In this case, LTE_UL_BW makees For the priority of up use still greater than or equal to making descending use, LTE_DL_BW as descending use priority still Greater than or equal to making up use.
Four, the transmission time configuration of basic reference signal.
The transmission cycle of basic reference signal is longer, can be such as 40ms/80ms/160ms, and sends in each cycle Once, the duration every time sent is shorter (less than 1ms, or less than 1 subframe lengths).Meanwhile, for uniform authorization frequency Composing and unlicensed spectrum, each cycle has one to send window, and each transmission window comprises the time that repeatedly sends, as long as arbitrarily One sends time interior transmission once.
When LTE_UL_BW is up PCell when LTE_DL_BW is descending PCell, use the cell#1 of LTE_DL_BW Downlink reference signal cycle can cycle of downlink reference signal than the cell#2 using LTE_UL_BW little because after The priority that person makees up use is high；And use cycle of the uplink reference signals of the cell#1 of LTE_DL_BW can be than use The cycle of the uplink reference signals of the cell#2 of LTE_UL_BW is big, because the priority that the former makees descending use is high.
Five, the type of basic reference signal.
Specifically, can be with the PSS/SSS/CRS/CSI-RS in multiplexing tradition LTE.New reference signal can also be defined, The newest reference signal need not use PSS/SSS, but a kind of signal of definition i.e. can indicate that this cell identity, and Join together also without PSS and SSS the identity of indicating cell, it is not required that the relative position of PSS/SSS indicates communication system System is FDD system or TDD system, because the structure of FDD and TDD is unified by technical scheme.
Six, the frequency domain configuration of basic reference signal: the transmission bandwidth of basic reference signal has only to take a part of RB (Resource Block, Resource Block).
Specifically, as it is shown on figure 3, these RB can be continuous print RB, and this part of continuous print RB position is in time Can regular change.Or these RB can be that discontinuous RB, these RB are uniformly distributed over the whole width or all Even it is distributed in a part of bandwidth that (such as some bandwidth needs to be available and leaves later business for and use, then on this fractional bandwidth Not sending basic reference signal, the RB therefore sending reference signal is uniformly distributed in other bandwidth), in this case, As shown in Figure 4, these RB positions can also regular change in time.
The continuous RB of the basic reference signal of above-mentioned transmission or the quantity of discontinuous RB, distributing position and Changing Pattern etc. are all Need to be stored in terminal, in order to terminal goes corresponding location finding reference signal according to these information of storage.Further, since Carrier frequency has been separated from employing in pairs, therefore uses the reference signal of cell#1 of LTE_DL_BW at band corresponding for LTE_DL_BW Sending on width, use the reference signal of the cell#2 of LTE_UL_BW to send in the bandwidth that LTE_UL_BW is corresponding, this is accomplished by The user of NR is compared with the user of LTE, in addition to search is for the frequency of descending LTE_DL_BW, also to search for for The frequency at the LTE_UL_BW place of row.
Seven is similar with reference signal, and MIB and other SIB (System Information Block, system information block) believes Breaths etc. can only send in a part of bandwidth, and the cycle longer (such as can shared by 40ms or 40 subframes time Long).MIB can also be transmitted according to the mode shown in Fig. 3 and Fig. 4 as basic reference signal.It addition, MIB and other The transmission time of SIB information and shared RB position can be different, but all without taking whole bandwidth.
Eight, owing to NR needing not distinguish between FDD and TDD, the tdd-that therefore SIB1 in former LTE system can be comprised This IE of config (information element) removes, and adds IE in SIB1 and point out as NR, then user is accordingly it is known that frame Structure is neither FDD is not TDD, but the frame structure of NR.
Visible, technical scheme does not only give paired carrier frequency using method in 5G NR, and gives Band width configuration under new frame structure, and the configuration that downlink reference signal etc. is in respective bandwidth so that carrier frequency energy in pairs Enough use, forward compatibility simultaneously flexibly.
