Description

Method, the network equipment and the terminal device of wireless communication

Background technique

Wireless telecom equipment is sent and received signal using time-division or frequency division manner at present, that is frequency division duplex (Fequency Division Duplex, referred to as " FDD "), time division duplex (Time Division Duplex, referred to as " TDD ") two ways.FDD is received and transmitted on two pairs of (pair) channels of separation.And TDD point is sent and received with the time, although sending and receiving all using the same frequency, transmitting-receiving uses different time-gap.Therefore in either fdd mode or tdd mode, in identical frequency, interior at the same time, wireless telecom equipment only exists in the state of receiving or sending.Full duplex (Full Duplex, referred to as " FD ") refers to that wireless device is received and transmitted simultaneously in identical frequency, same time.Due to transmitting signal be in equipment it is known, theoretically subtract transmitting signal in the signal received, realize the influence for completely eliminating transmitting signal, double channel capacity.

For ease of description, it will be established after RRC connect with the network equipment, the terminal device for receiving the specific uplink and downlink proportion of terminal device that the network equipment is sent is known as highest version terminal device；The terminal device of the specific uplink and downlink proportion of the terminal device that network equipment transmission cannot be received is known as generic terminal devices, but title without being limited thereto of the embodiment of the present invention.

In embodiments of the present invention, optionally, it is established before RRC connect in the network equipment and terminal device, terminal device can pass through (the System Information Block of system information block 1, referred to as " SIB1 ") the specific uplink and downlink proportion of cell is obtained, and all terminals in the same cell are set The specific uplink and downlink proportion of the cell of the standby cell being both configured to where it, it is established after RRC connect in the network equipment and terminal device, the network equipment can send the specific uplink and downlink proportion of terminal device to the section terminating equipment in cell, the specific uplink and downlink proportion of terminal device actually obtained for the terminal device of highest version and the specific uplink and downlink of cell matches two proportions, but the specific uplink and downlink proportion of terminal device is used to be communicated with the network equipment, and the specific uplink and downlink of the terminal device that the network equipment also sends storage to terminal device matches, in order to when updating uplink and downlink proportion, the uplink and downlink proportion that terminal device is new is notified in the current downlink subframe resource of terminal device.And generic terminal devices are due to the signaling of the specific uplink and downlink proportion of the carried terminal equipment that cannot correctly demodulate network equipment transmission, still communicated using the specific uplink and downlink proportion of cell with the network equipment, thus, the uplink and downlink of different terminal equipment configuration in the same cell matches different, the full duplex ability that the network equipment can be utilized, improves frequency spectrum resource utilization rate.

Optionally, the network equipment changes the uplink and downlink proportion of highest version terminal device by other forms.For example, the full duplex ability of network equipment notice terminal device oneself.Terminal device is according to oneself business load situation, to a kind of specific uplink and downlink proportion of terminal device of network device requests.The network equipment confirms after the uplink and downlink proportion request for receiving terminal device to terminal device.Confirmation message can only carry confirmation message, can also carry the practical specific uplink and downlink of the terminal device distributed to terminal device and match.

Optionally, in S220, the network equipment can send different the second uplink and downlink proportions to multiple terminal devices.That is the network equipment can send the specific uplink and downlink proportion of different terminal devices at least two terminal devices, at this point, can have at least three kinds different uplink and downlink proportions in a cell.Such as, the network equipment can send the specific uplink and downlink proportion of terminal device to terminal device 1, such as uplink and downlink proportion 0, the specific uplink and downlink proportion of terminal device is sent to terminal device 2, such as uplink and downlink proportion 1, other terminal devices still configure the specific uplink and downlink proportion of cell, such as uplink and downlink proportion 2 in terminal device 3 and cell；The network equipment can also send the specific uplink and downlink proportion of terminal device to one group of terminal device, such as uplink and downlink proportion 4, the specific uplink and downlink proportion of terminal device is sent to another group of terminal device, such as uplink and downlink proportion 6, the specific uplink and downlink proportion of cell, such as uplink and downlink proportion 3 are still configured on other terminal devices in cell.But the present invention is not limited thereto.

In the present invention is implemented, optionally, it when the state for determining the terminal device is RRC Idle state, is matched according to first uplink and downlink and is carried out wireless communication with the terminal device.That is, when the terminal device of highest version is in RRC free time (RRC-idle) state, in order to reduce the additional expense of the specific bound proportion bring of terminal device to the greatest extent, terminal device can be matched according to current uplink and downlink proportion is reset to the specific uplink and downlink of cell with the instruction of the agreement of the network equipment or the network equipment in advance.

In turn, since paging channel is sent by Physical Downlink Shared Channel (Physical Downlink Share Channel, referred to as " PDSCH ").Therefore, for the terminal device in idle state, the network equipment sends paging channel in the downlink subframe in the specific uplink and downlink proportion of cell.And for the terminal device in connection (Connected) state, the network equipment sends paging in the downlink subframe in the current uplink and downlink proportion of terminal device.Terminal device is according to current uplink and downlink proportion it is known where receiving Physical Downlink Control Channel (Physical Downlink Control Channel, referred to as " PDCCH "), and according to radio network temporary identifier P-RNTI determine PDCCH instruction PDSCH resource in whether have paging information.

Optionally, in S220, the network equipment can send RRC dedicated signaling to the terminal device, which carries second uplink and downlink proportion；Or,

The network equipment can send particular terminal device search space to the terminal device, which carries second uplink and downlink proportion；Or,

The network equipment sends enhanced Physical Downlink Control Channel ePDDCH to the terminal device, which carries second uplink and downlink proportion.

Specifically, established after RRC connect in the network equipment and terminal device, the network equipment can each terminal device into cell send the uplink and downlink for the terminal device respectively and match.The network equipment can carry RRC dedicated signaling in the PDSCH resource by indicating downlink in the initial uplink and downlink proportion of terminal device (in the specific uplink and downlink proportion of cell), which carries second uplink and downlink proportion；Or the specific uplink and downlink proportion of terminal device that the network equipment passes through the specific search space of PDCCH terminal device or ePDCCH channel notification the terminal device terminal device.

Preferably, it in S220, is matched by the specific uplink and downlink of RRC signaling configurating terminal device, and dispatch the terminal device of different ratio by PDCCH/ePDCCH, realizes the quick variation of cell actually downlink resource.

As an example it is assumed that three terminal devices of scheduling sentence proportion 1 and proportion 0,6 respectively.Wherein, 0 corresponding 0~9 work song frame is matched successively are as follows: DSUUUDSUUU, 1 corresponding 0~9 work song frame of proportion is successively are as follows: DSUUDDSUUD, match 6 corresponding 0~9 work song frames successively are as follows: DSUUUDSUUD, D indicates that downlink subframe, U indicate that sub-frame of uplink, S indicate special subframe.

If the terminal device of scheduling proportion 1 and proportion 0, actually may be used as 6 subframes of uplink, is+2 descending pilot frequency time slots of 4 subframes (Downlink Pilot Time Slot, referred to as " DwPTS ") as downlink.If the terminal device of scheduling proportion 1 and proportion 6.5 subframes that so actually may be used as uplink are 4 subframe+2DwPTS as downlink.It can be seen that even if proportion Variation it is slow, using RRC signaling, the terminal device of different ratio can also be in by dispatching, obtain dynamic uplink and downlink proportioning effect.

Optionally, in S220, the network equipment can send the first proportion matched including second uplink and downlink to each terminal device in the set of terminal including the terminal device and configure message, which configures the group serial number that message includes the set of terminal.

That is, the network equipment can send the first proportion configuration message matched including uplink and downlink to all terminal devices for belonging to a set of terminal, terminal device in the set of terminal is according to the group serial number carried in the first proportion configuration message, it determines that uplink and downlink proportion is the specific uplink and downlink proportion of terminal device that the network equipment is distributed to oneself, is carried out wireless communication later according to the specific uplink and downlink proportion of the terminal device with the network equipment.Such as the network equipment can be matched by the specific uplink and downlink of multicast (UE Group Specific) signaling carried terminal equipment, it is possible thereby to reduce signaling overheads.Each set of terminal can configure different uplink and downlink proportions, can make full use of the full-duplex preformance of the network equipment, improve frequency spectrum resource utilization rate.

Optionally, in S220, the network equipment can be by including that each terminal device of the corresponding wave beam of set of terminal of the terminal device into the set of terminal sends the second proportion configuration message including second uplink and downlink proportion.

Specifically, the network equipment can work on multiple wave beams, as shown in figure 3, each wave beam has specific uplink and downlink to match, so that the multiple terminal devices to work on this wave beam form a group.The division that set of terminal is carried out by wave beam can make the terminal device in the same set of terminal match using identical uplink and downlink, so that the terminal device transmission direction (upstream or downstream) in the same set of terminal is unanimously, reduce the interference between terminal device.The second proportion configuration message can carry the beam information of wave beam, such as the beam information can be the serial number of wave beam.Can also be by the corresponding pre-coding matrix of wave beam, the physical channel transformat of wave beam pre-coding matrix serial number and the specific uplink and downlink proportion message of transmission terminal equipment determines the corresponding wave beam of terminal.

In embodiments of the present invention, optionally, the entry-into-force time for the uplink and downlink proportion that the network equipment and terminal device can make an appointment new, such as uplink and downlink proportion that can be new in next subframe after terminal device is properly received the new uplink and downlink proportion that the network equipment is sent come into force.The network equipment can also send instruction information to terminal device, indicate the entry-into-force time of new uplink and downlink proportion, this is not limited by the present invention.

In embodiments of the present invention, optionally, second uplink and downlink proportion is any one uplink and downlink proportion in the first uplink and downlink proportion set, and first uplink and downlink proportion collection is combined into the set of the proportion of uplink and downlink shown in the following table 1:

Table 1

At the downlink subframe moment, the network equipment can send downlink data packet to terminal device；At the sub-frame of uplink moment, terminal device can send upstream data packet to the network equipment.At the special subframe moment, the network equipment can send downlink data packet to terminal device, but terminal device cannot send upstream data packet to the network equipment, thus special subframe is generally also taken as downlink subframe to handle.

As can be seen from Table 1, subframe 3,4, the network equipment can be by dispatching the terminal of not different ratio in 7,8 and 9 corresponding resources, work is in a full-duplex mode, network equipment working in a full-duplex mode when, cell specific uplink and downlink proportion is not actual resource service condition in cell, but the uplink and downlink resource used to plaintext terminal device matches.

In embodiments of the present invention, optionally, second uplink and downlink proportion is any one uplink and downlink proportion in the second uplink and downlink proportion set, and second uplink and downlink proportion collection is combined into the set of the proportion of uplink and downlink shown in the following table 2:

Table 2

Wherein, D indicates that downlink subframe, U indicate that sub-frame of uplink, S indicate special subframe, and X expression is not construed as limiting, and can be sub-frame of uplink, downlink subframe, the subframe that blank subframe or other special uplink and downlink resources divide.

As can be seen from Table 2, subframe 2 is D, and subframe 5 is U, when subframe 2 and 5 can be made to be used cooperatively with other in this way, realizes the transmission direction flexible configuration of subframe 2 and subframe 5.More resources are allowed flexibly to be scheduling to full duplex resource.In addition only increase a kind of uplink and downlink proportion, it can be still using 3 bit informations mark uplink and downlink proportion set.Additional expense is not generated.

After proportion 7 introduces, important down channel may be subjected to the interference of the uplink signal of terminal transmission in subframe 5.Such as include in subframe 5 may be by the schedule broadcast message (40ms, 80ms, 160ms) in period, such as system information block (System Information Block, referred to as " SIB ").But it is this to avoid to realize by the scheduling of the network equipment since the period of scheduling is greater than the length of a frame, it is not embodied by uplink and downlink proportion.I.e. in the transmission resource of SIB1, the network equipment does not dispatch terminal device and sends any uplink signal.And secondary synchronization signal (Secondary Synchronization Signal, referred to as " SSS ") is on 72 subcarriers at the center in the last symbol of subframe 5, it, will be unaffected if it is the transmission of PUCCH.If it is PUCCH, the transmission of PUSCH is needed through punching, and rate-matched avoids the resource where SSS.

In embodiments of the present invention, optionally, it is sub-frame of uplink which, which matches 7 corresponding subframes 0, which is used for transmission tip reference signal SRS and/or leading 4.

Subframe 0 is all downlink subframe in the 7 kinds of proportions defined at present in LTE system.In order to improve spectrum utilization efficiency, subframe 0 can be designed as U subframe.But Physical Broadcast Channel (Physical Broadcast Channel, referred to as " PBCH ") and primary synchronization signal (Primary Synchronization Signal, referred to as " PSS ") be that highly important channel and reference signal are accessed for terminal device.If network equipment working in a full-duplex mode, may cause terminal device and can not be synchronized and system information in these resources.Therefore it needs to avoid the network equipment in these resources using full-duplex mode.It can be avoided by the way of time-division and frequency division.

Fig. 4 shows the channel of PBCH in subframe 0, it can be seen that subframe 0 includes PBCH channel (6, the center RB of system bandwidth, common CP, on 0~3 symbol of 1 time slot) and SSS (1 In the last symbol of time slot).Therefore, the network equipment should avoid these resources from being scheduled as full-duplex mode.

And since terminal device needs the measurement by the specific reference signal of cell (Cell-Specific Reference Signals, referred to as " CRS ") Lai Jinhang path loss, in order to not influence the measurement of path loss.It needs to retain a part of half-duplex resource and is used for transmission CRS and and terminal device path loss measurement.Only having a small amount of symbol in this way in subframe 0 may be used as uplink.There is no continuous 3 symbols, therefore it is only capable of Physical Random Access Channel (the Physical Random Access Channel with uplink, referred to as " PRACH ") channel, such as it is only used for transmission Preamble Format 4 and/or tip reference signal (Sounding Reference Signal, referred to as " SRS ").This special sub-frame of uplink is known as T subframe by the present invention.

For having the transmission of PSS, as shown in Figure 5 in subframe 1 and subframe 6.It is with the PBCH in subframe 0 different, PSS itself should not CRS demodulate.Thus, it is only required to which 6 RB among the system bandwidth where PSS are avoided, does not need entire symbol and be used as half-duplex downlink.(frequency division avoids, PSS.Therefore it can be dispatched and be realized by PDCCH, without being embodied in uplink and downlink matches)

In embodiments of the present invention, optionally, second uplink and downlink proportion is the uplink and downlink proportion of the secondary carrier of the terminal device, this method 200 further include:

S240, it receives the terminal device and passes through the ascending control information of the Physical Uplink Control Channel PUCCH configured on the Pscell of main plot the secondary carrier sent, wherein, which includes at least one of following message: hybrid automatic repeat-request HARQ feedback confirmation message, channel quality information and scheduling request information.

Specifically, possible hybrid automatic repeat-request HARQ feedback confirmation message, transmission of channel quality information, the ascending control informations such as scheduling request in PUCCH channel.Lead to PUCCH and downlink resource conflict, special PDCCH channel.Fairly simple mode avoids PUCCH and downlink resource conflict using the method for carrier wave polymerization (Carrier aggregation, referred to as " CA ").The subcarrier that full duplex works is determined as secondary carrier, the ascending control information of secondary carrier passes through the PUCCH channel feedback of main carrier.Such as the uplink and downlink in table 2 can be matched 7 and only be used on the terminal device for supporting carrier wave polymerization.Avoid the PUCCH channel and PDCCH conflict in secondary carrier.

If the influence to existing protocol can be bigger not by the way of carrier wave polymerization, only it is illustrated by taking a kind of possible proportion as an example below, a kind of uplink and downlink newly increased is as shown in table 3 with when parameter.

Table 3

T is ascending resource, wherein CRS, PBCH, and the symbol where SSS does not send any uplink signal, and other symbols can be used for sending Preamble format 4 and/or SRS.

Therefore, it is necessary to the PRACH resource location of corresponding newly-increased proportion is defined in 3GPP 36.211.So that PRACH is located in effective resource, it is required that PRACH resource can indicate into ascending resource the sure resource for being used to emit PRACH.Such as some shorter resources in subframe 0 here.For example Preamble, now with 5 kinds of length, wherein format 0 occupies 1 subframe, and format 1,2 occupies 2 subframes, and format 3 occupies 3 subframes.Format 4 occupies 2 OFDM symbols.So for only supporting format 0,1,2 and 4 on this proportion time, due to not continuous 3 sub-frame of uplink.The position that can specify that legal resource according to different proportions, is indicated in agreement with 4 parameters at presentf_RAIndicate the frequency location that each PRACH channel of frequency division in synchronization is indicated on the basis of frequency offset parameters (Prach-Frequency Offset)；Indicate the position of the radio frames of PRACH channel, 0 indicates whole radio frames, and 1 is odd number radio frames, and 2 be even number radio frames；Refer to PRACH in the preceding field or rear field of radio frames, 0 is preceding field, and 1 is rear field；Indicate PRACH channel upper sub-frame number in 5ms field, it is short sequence that band *, which is indicated on UpPTS,.

Uplink power control has a kind of cumulative type.It is adjusted by PDCCH indicated horsepower, i.e., K below_puschUplink PUSCH power adjustment δ_PUSCH,c.PUSCH power in so the i-th sub-frame of uplink is according to f_c(i)=f_c(i-1)+δ_PUSCH,c(i-K_pusch) adjustment power.

In order to reduce the reception bit error rate, HARQ mechanism is used in LTE system.Receive information need by feedback NACK ACK the bit error rate is received using retransmitting to merge to reduce for the content that cannot be once properly received.Since downlink PDSCH channel is asynchronous HARQ mechanism in LTE, and uplink PUSCH channel is synchronous HARQ mechanism.That is it if PDSCH reception failure, can retransmit at any time.And PUSCH reception failure, it is necessary to be retransmitted in scheduled resource.

Terminal device needs to meet just send PUSCH:(1 into one of two conditions) uplink authorization (UL grant) or the response from random access that PDCCH is dispatched are received, or be semi-statically configured；(2) physical mixed automatic re-transmission indicating channel (Physical Hybrid ARQ Indicator Channel, letter are received Referred to as " PHICH ") it is designated as NACK, need non-adaptive re-transmission.For the PUSCH of the uplink in n sub-frame transmission, terminal thinks to have fed back whether the network equipment received correctly the information of the PUSCH in the resource of n+Kphich.

In addition the PUCCH of each uplink can carry for n-k k ∈ K, PDSCH or by the ACK of (the Semi Persistent Schedule, referred to as " SPS ") of the semi-persistent scheduling of PDCCH NACK feedback information.For the proportion more than downlink subframe, the downlink distribution index (Downlink Assignment Index, referred to as " DAI ") in the PDCCH of n-k ' proportion subframe, PUCCH can carry n-k, the ACK of k ∈ K, PDSCH or PDCCH NACK feedback information.

For the angle of uplink, terminal device has sent PUSCH in n subframe, then terminal device know the PHICH sent in the downlink subframe of n+Kphich be feedback n subframe on PUSCH whether receive correct NACK ACK information.

For the angle of downlink, if terminal device has received PHICH in n subframe, PHICH is the PUSCH sent on n-k for terminal device.

For from the angle of downlink, the PDCCH sent in n subframe dispatches PUSCH information, and the PUSCH in the sub-frame of uplink of the n+k of actual scheduling carries out data transmission.Or the NACK of PHICH instruction is had received in subframe n, terminal can also carry out data transmission in the PUSCH in the sub-frame of uplink of n+k.

Downlink can also use Transmission Time Interval (Transmission Time Interval, referred to as " TTI ") binding (Bundling) mode, if terminal device detects PDCCH retransmission instruction in subframe n, or the NACK in subframe n-l detection PHICH instruction, PUSCH transmission can be carried out in n+k subframe.

In embodiments of the present invention, it is alternatively possible to be further reduced the interference of PUCCH and PDCCH channel by the way of time-division or frequency division, as shown in fig. 7, second uplink and downlink matches corresponding m₁Preceding T in a subframe_mA symbol is used for transmission PDCCH, rear T_nA symbol is used for transmission PUCCH, m₁、T_mAnd T_nFor positive integer, and T_mWith T_nAnd be less than or equal to the first preset threshold；

As shown in figure 8, second uplink and downlink matches corresponding m₂The two sides F of the corresponding system bandwidth of each subframe in a subframe_mA subcarrier is used for transmission PUCCH, the intermediate F of the system bandwidth_nA subcarrier is used for transmission PDCCH, m₂、F_mAnd F_nFor positive integer, and F_mWith F_nAnd be less than or equal to the second preset threshold；

Wherein, 0≤m₁≤ N, 0≤m₂≤N-m₁, N is the number for the subframe that a radio frames include.For example, the number for the subframe that a radio frames include in existing LTE system is 10.

Optionally, which can be any positive integer for the symbolic number for including less than or equal to each subframe, which can be any positive integer of the corresponding sub-carrier number of system bandwidth corresponding less than or equal to each subframe.

That is, in certain full duplex subframes in a frame interference of PUCCH and PDCCH can be avoided by the way of the time-division, and the interference of PUCCH and PDCCH can be avoided by the way of frequency division in certain full duplex subframes.For example, uplink and downlink, which matches in subframe 0 and subframe 5 in 0~6, can guarantee that downlink PDCCH channel design is constant by the way of the time-division；It can guarantee that uplink PUCCH channel design is constant by the way of frequency division in subframe 2 in uplink and downlink proportion 0~6.But the present invention is not limited thereto.

Therefore, the method of the wireless communication of the embodiment of the present invention, the network equipment can be established after RRC connect with terminal device, the uplink and downlink proportion of terminal device is reconfigured for match different uplink and downlinks proportions from the uplink and downlink of the cell where the terminal device as the uplink and downlink of the cell where terminal device proportion, thus the network equipment can be carried out wireless communication from the different terminal equipment in the same cell using different uplink and downlink proportions, therefore, the full duplex ability that the network equipment can be utilized, improves frequency spectrum resource utilization rate.
