Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts Example, shall fall within the protection scope of the present invention.

Referring to Fig. 1, the downlink feedback method of Fig. 1 is applied to mobile communication terminal, as shown in Figure 1, under the present embodiment Row feedback method the following steps are included:

Step 101 receives the Physical Downlink Shared Channel PDSCH letter that network side equipment is sent on n-th of slot s lot Number.

In the present embodiment, network side equipment can first pass through PDCCH (Physical Downlink Control in advance Channel, Physical Downlink Control Channel) specify transmission PDSCH (Physical Downlink Shared Channel, physics DSCH Downlink Shared Channel) signal running time-frequency resource position, in this way, mobile communication terminal can be after interpreting PDCCH, according to PDCCH In specify running time-frequency resource position on receive PDSCH signal.Hence, it will be appreciated that, n-th of slot s lot in this step is by net Network side apparatus preassigns.

Wherein, PDSCH signal can be understood as signal of the network side equipment by PDSCH transmission, such as downlink data data； N is the integer more than or equal to 0.

If step 102, the Downlink Control Information DCI for dispatching PDSCH do not include timing indication field, in t-th of slot The upper physical uplink control channel PUCCH signal sent for feeding back the PDSCH signal transmission situation.

In the present embodiment, the DCI (Downlink Control Information, Downlink Control Information) of PDSCH is dispatched In do not include timing instruction (PDSCH-to-HARQ-timing indicator) field, such as dl-data-to-UL-ACK field, Wherein, timing indication field is used to indicate the sequential relationship between downlink data transmission and HARQ-ACK feedback, i.e. mobile communication Terminal carries out downstream feedback on receiving which slot after downlink data.When not including timing indication field in DCI Mobile communication terminal can be determined and be sent on t slot for feeding back the PDSCH signal transmission situation according to preset rules PUCCH (Physical Uplink Control Channel, physical uplink link control letter) signal.

In this step, PUCCH signal can be understood as the signal transmitted by PUCCH, and specifically, PUCCH signal can be with Showing as HARQ ACK (Acknowledgment, affirmative acknowledgement (ACK))/NACK, (Negative Acknowledgment, negates back It answers).Wherein, the t is the integer more than or equal to n+k, and the k is the integer more than or equal to 0, it should be understood that, k is whole Number.

In this way, mobile communication terminal receives network on n-th of time slot even if not including timing indication field in DCI After the PDSCH signal that side apparatus is sent, the PUCCH for feeding back the PUSCH signal transmission situation is sent on t-th of slot Signal, wherein the t is the integer more than or equal to n+k, and the k is the integer more than or equal to 0, so as to specification DCI In when not including timing indication field, the determination of the slot for downstream feedback, while saving overhead.

In the present embodiment, k value can determine in several ways, be described as follows:

Method of determination one, the k are predefined.

In the method for determination, the predefined k value of system, such as: system k value can be directly fixed in network side equipment with In the communication protocol of mobile communication terminal.In this way, mobile communication terminal and network side equipment can be directly from communication protocols K value is read, and further determines the value of t according to k value, is used to indicate without network side equipment to mobile communication terminal transmission to refer to The signaling for showing k value, such as RRC (Radio Resource Control, wireless heterogeneous networks) signaling, so as to the system of saving Signaling overheads.

Method of determination two, the k are obtained by implicit.

In the method for determination, system can predefine numerology (messaging parameter) and the one-to-one correspondence of k value closes System, and above-mentioned corresponding relationship is directly fixed in the communication protocol of network side equipment and mobile communication terminal, wherein Numerology includes subcarrier spacing and CP (Cyclic prefix, cyclic prefix) length.

In this way, when mobile communication terminal gets numerology, so that it may according to numerology from communication protocol The corresponding k value of the numerology is read, and further determines the value of t according to k value, it is whole to mobile communication without network side equipment End sends the signaling being used to indicate to indicate k value, so as to the signaling overheads for the system of saving.

Method of determination three, the k are pre-configured with by the network side equipment by radio resource control RRC signaling.

In the method for determination, network side equipment predefines k value, then is informed by RRC signaling to mobile communication terminal Predefine k value.

It is different from method of determination one and method of determination two, this method of determination can change k value by network side equipment, in turn The flexibility of k value configuration can be improved.

Certainly, mobile communication terminal can also determine that k value, the embodiment of the present invention are not construed as limiting this by other means. It should be understood that, network side equipment can also obtain k value by same mode, and the value of t is further determined according to k value, from And after PDSCH signal being sent on n-th of slot, mobile communication terminal transmission can be received on t-th of slot PUCCH signal.

In the present embodiment, network side equipment can pass through SFI (Slot format information, time slot format letter Breath) to mobile communication terminal carry out UL-DL (uplink-downlink) configuration, can with but be not limited only to be used to indicate the symbol in slot Type.Wherein, UL-DL configuration includes UL slots/symbols (ascending time slot/symbol), DL slots/symbols (downlink Time slot/symbol) and Unknown slots/symbols (unknown time slot/symbol), UL slots/symbols be only used for uplink biography Defeated, DL slots/symbols is only used for downlink transfer, and Unknown slots/symbols is a kind of flexible slots/ Symbols (flexible slots/symbols) can be used for uplink or downlink transfer or without any transmission.

Further, SFI include but are not limited to semi-static SFI (semi-static time slot format information) and Dynamic SFI (dynamic time slot format information).

In NR (New Radio, wireless access) unpaired spectrum (unpaired frequency spectrum) or TDD (Time Division Duplexing, time division duplex) in system, network side equipment can pass through cell-specific higher (terminal is set by layer signaling (cell-specific high-level signaling) or UE-specific higher layer signaling Standby dedicated high-level signaling) to mobile communication terminal transmission semi-static SFI, it is semi-static to be carried out to mobile communication terminal UL-DL configuration；It can also be by group-common PDCCH (organizing public Physical Downlink Control Channel) to mobile communication terminal Dynamic SFI is sent, to carry out dynamic UL-DL configuration to mobile communication terminal；Alternatively, being sent out simultaneously to mobile communication terminal Semi-static SFI and dynamic SFI is sent, to carry out UL-DL configuration to mobile communication terminal.It should be noted that if Network side equipment sends semi-static SFI and dynamic SFI to mobile communication terminal simultaneously, then and dynamic SFI The slots/symbols that Unknown is designated as in semi-static SFI can be modified.

Scene is configured to various UL-DL below, the form of expression of t-th of slot is described as follows:

If scene one, the DCI do not include timing indication field, and the mobile communication terminal receives the network side The time slot format information SFI for the semi-static sign pattern being used to indicate in slot that equipment is sent, then t-th of slot Are as follows: the first aim slot after the m-1 slot of the semi-static SFI instruction, wherein the target slot includes Uplink symbol UL symbol and/or unknown symbols Unknown symbol, the m are the integer more than or equal to n+k, the t More than or equal to the m.

It is to be understood that in this scenario, no matter mobile communication terminal is only to receive semi-static SFI, that is, receive To semi-static SFI, dynamic SFI is not received；Still semi-static SFI and dynamic SFI is received, Mobile communication terminal determines the first aim after the m-1 slot that t-th of slot is semi-static SFI instruction slot。

Further, described if the DCI includes PUCCH resource instruction (PUCCH resource indicator) PUCCH resource indicates that the transfer resource for being used to indicate the PUCCH signal, the transfer resource of the PUCCH signal include transmission The primary sign start symbol and symbol lengths symbol duration of the PUCCH signal, then the PUCCH signal Transfer resource in UL symbol and/or the Unknown symbol of the target slot.

In the application scenarios, in summary, the target slot meets:

A) the target slot is the slot after the m-1 slot that semi-static SFI is indicated；

B) the target slot includes UL symbol and/or Unknown symbol；

C) it includes UL that the transfer resource of the indicated PUCCH of PUCCH resource instruction, which falls into the target slot, in DCI In symbol and/or Unknown symbol.

In this way, mobile communication terminal can transfer resource in first aim slot, i.e. t-th of slot with PUCCH PUCCH signal is transmitted on matched symbol, when so as to not include timing indication field in specification DCI, is used for downstream feedback Slot determination.

In addition, can effectively the system of saving be used to indicate using the sign pattern in semi-static SFI instruction slot The signaling overheads of SFI.

For convenience of understanding, it is equal to 4 below with k；It is 12 (numbers that the primary sign of the PUCCH signal is transmitted in instruction in DCI Since 0), symbol lengths 2；The configuration information of the n-th+4 slot is in semi-static SFI configuration (DDDDDDDDDDXXXU), the configuration information of the n-th+5 slot is (UUXDDDDDDDDDDD), and the n-th+6 slot's matches confidence Breath be (DDDDDDDDDDXXUU) for, for the PUCCH signal transfer resource the target slot UL symbol And/or the different modes in Unknown symbol are illustrated.

Wherein, U indicates that UL symbol, D indicate that DL symbol, X indicate Unknown symbol.In the application scenarios In, it is indicated according to the PUCCH resource of DCI, it is known that it is XU with the matched symbol of the transfer resource of PUCCH in the n-th+4 slot, the With the matched symbol of the transfer resource of PUCCH it is DD in n+5 slot, is matched with the transfer resource of PUCCH in the n-th+4 slot Symbol be UU.Mode one, the PUCCH signal transfer resource in the UL symbol of the target slot.

In this approach, the target slot meets:

B) the target slot includes UL symbol and/or Unknown symbol；

C) it includes UL that the transfer resource of the indicated PUCCH of PUCCH resource instruction, which falls into the target slot, in DCI In symbol.

In this mode, since the transfer resource of the PUCCH signal is in the UL symbol of the target slot, then Mean that mobile communication terminal can only be designated as the fractional transmission PUCCH signal of UL symbol in semi-static SFI.

Therefore, mobile communication terminal cannot transmit the PUCCH signal on the n-th+4 slot and the n-th+5 slot, can To transmit the PUCCH signal on the n-th+6 slot, then in the application scenarios, only the n-th+6 slot are the n-th+3 Target slot after slot, and then know that t-th of slot is the n-th+6 slot.

Mode two, the PUCCH signal transfer resource the target slot UL symbol or Unknown In symbol.

In this approach, the target slot meets:

B) the target slot includes UL symbol and/or Unknown symbol；

C) it includes UL that the transfer resource of the indicated PUCCH of PUCCH resource instruction, which falls into the target slot, in DCI In symbol or Unknown symbol.

In this mode, due to the transfer resource of the PUCCH signal in the UL symbol of the target slot or In Unknown symbol, then mean mobile communication terminal can semi static SFI be designated as UL symbol or The fractional transmission PUCCH of unknown symbol, therefore UE can be described in the n-th+4 slot and the n-th+6 slot transmission PUCCH signal, then in the application scenarios, the n-th+4 slot and the n-th+6 slot are the target after the n-th+3 slot slot.From the foregoing, it will be observed that t-th slot is the first aim slot after the n-th+3 slot, therefore, t-th of slot is the N+4 slot.

It certainly, in some embodiments, can not also include PUCCH resource instruction in DCI.In the application scenarios, If the DCI does not include PUCCH resource instruction, mobile communication terminal can by other means, as RRC signaling obtains PUCCH resource instruction, wherein PUCCH resource indicates to be used to indicate the transfer resource of PUCCH, the PUCCH signal as described in transmitting Primary sign start symbol and symbol lengths symbol duration.In this way, mobile communication terminal can be in the target PUCCH signal is transmitted on the transfer resource matched UL symbol or Unknown symbol with PUCCH of slot, so as to When not including timing indication field in specification DCI, the determination of the slot for downstream feedback.

If scene two, the DCI do not include timing indication field, and the mobile communication terminal receives the network side The semi-static SFI and dynamic SFI that equipment is sent, then t-th of slot are as follows: m-1 of the dynamic SFI instruction First aim slot after slot, wherein the target slot includes UL symbol and/or Unknown symbol, institute Stating m is the integer more than or equal to n+k, and the t is more than or equal to the m.

It is to be understood that in this scenario, mobile communication terminal is only receiving semi-static SFI and dynamic When SFI, the first aim slot after the m-1 slot that t-th of slot is dynamic SFI instruction is just determined.

Further, if the DCI includes PUCCH resource instruction, the PUCCH resource instruction is used to indicate described The transfer resource of PUCCH signal, the transfer resource of the PUCCH signal include the primary sign for transmitting the PUCCH signal Start symbol and symbol lengths symbol duration, then the transfer resource of the PUCCH signal is in the target slot UL symbol and/or Unknown symbol in.

In the application scenarios, in summary, the target slot meets:

A) the target slot is the slot after the m-1 slot of dynamic SFI instruction；

B) the target slot includes UL symbol and/or Unknown symbol；

In addition, compared to scene one, it, can be real-time dynamicly using the sign pattern in dynamic SFI instruction slot It indicates the sign pattern in slot, and then improves the flexibility ratio of the sign pattern configuration in slot.For convenience of understanding, below with k Equal to 4；It is 12 (number is since 0), symbol lengths 2 that the primary sign of the PUCCH signal is transmitted in instruction in DCI；? The configuration information of the n-th+4 slot is (DDDDDDDDDDXXXX) in semi-static SFI configuration, is matched in dynamic SFI The configuration information of the n-th+4 slot is (DDDDDDDDDDXXXU) in setting, the n-th+5 in semi-static SFI configuration The configuration information of slot is (DDDDDDDDDDXXXX), and the configuration information of the n-th+5 slot is in dynamic SFI configuration (DDDDDDDDDDXXUU) for, for the PUCCH signal transfer resource the target slot UL symbol and/ Or the different modes in Unknown symbol are illustrated.

Wherein, U indicates that UL symbol, D indicate that DL symbol, X indicate Unknown symbol.In the application scenarios In, it is indicated according to the PUCCH resource of DCI, it is known that the biography in semi-static SFI configuration in the n-th+4 slot with PUCCH Defeated resource matched symbol is XX, matched with the transfer resource of PUCCH in the n-th+4 slot in dynamic SFI configuration Symbol is XU, and the matched symbol of transfer resource in semi-static SFI configuration in the n-th+5 slot with PUCCH is XX, The matched symbol of transfer resource in dynamic SFISFI configuration in the n-th+5 slot with PUCCH is UU.

Mode one, the PUCCH signal transfer resource in the UL symbol of the target slot.

In this approach, the target slot meets:

A) the target slot is the slot after the m-1 slot of dynamic SFI instruction；

B) the target slot includes UL symbol and/or Unknown symbol；

In this mode, since the transfer resource of the PUCCH signal is in the UL symbol of the target slot, then Mean that mobile communication terminal can only be designated as the fractional transmission PUCCH signal of UL symbol in dynamic SFI.

Therefore, mobile communication terminal cannot transmit the PUCCH signal on the n-th+4 slot, can be at the n-th+5 The PUCCH signal is transmitted on slot, then in the application scenarios, only the n-th+5 slot are the target after the n-th+3 slot Slot, and then know that t-th of slot is the n-th+5 slot.

In this approach, the target slot meets:

A) the target slot is the slot after the m-1 slot of dynamic SFI instruction；

B) the target slot includes UL symbol and/or Unknown symbol；

In this mode, due to the transfer resource of the PUCCH signal in the UL symbol of the target slot or In Unknown symbol, then mean mobile communication terminal can dynamic SFI be designated as UL symbol or The fractional transmission PUCCH of unknown symbol, therefore UE can be described in the n-th+4 slot and the n-th+5 slot transmission PUCCH signal, then in the application scenarios, the n-th+4 slot and the n-th+5 slot are the target after the n-th+3 slot slot.From the foregoing, it will be observed that t-th slot is the first aim slot after the n-th+3 slot, therefore, t-th of slot is the N+4 slot.

It certainly, in some embodiments, can not also include PUCCH resource instruction in DCI.In the application scenarios, If the DCI does not include PUCCH resource instruction, mobile communication terminal can by other means, as RRC signaling obtains PUCCH resource instruction, wherein PUCCH resource indicates to be used to indicate the transfer resource of PUCCH, the PUCCH signal as described in transmitting Primary sign start symbol and symbol lengths symbol duration, then mobile communication terminal can be in target slot Transmission PUCCH signal is matched on UL symbol or Unknown symbol with the transfer resource of PUCCH, so as to standardize When not including timing indication field in DCI, the determination of the slot for downstream feedback.

If scene three, the mobile communication terminal connect and do not receive the semi-static SFI that the network side equipment is sent, institute Stating t-th of slot is the n-th+k slot.

In this scenario, no matter whether network side equipment includes PUCCH resource instruction, mobile communication terminal clock in DCI The PUCCH signal is transmitted on the n-th+k slot.

Further, which may include that mobile communication terminal does not receive semi-static SFI, but receives The first sub-scene and mobile communication terminal of dynamic SFI does not receive semi-static SFI and dynamic SFI The second sub-scene.

For the first sub-scene, no matter the PUCCH resource that DCI includes indicates whether indicate with dynamic SFI n-th+4 The configuration information conflict of a slot, mobile communication terminal transmit PUCCH signal on the n-th+k slot.

It is equal to 4 with k；It is 12 (number is since 0) that the primary sign of the PUCCH signal is transmitted in instruction in DCI, and symbol is long Degree is 2；For the configuration information of the n-th+4 slot is (DDDDDDDDDDDDDD) in dynamic SFI configuration, to DCI packet The scene that the PUCCH resource instruction included conflicts with the configuration information of dynamic SFI the n-th+4 slot indicated is illustrated.

Wherein, D indicates DL symbol.In the application scenarios, indicated according to the PUCCH resource of DCI, it is known that the n-th+4 In slot with the matched symbol of the transfer resource of PUCCH be DD.

In the application scenarios, even if the n-th+4 that the PUCCH resource instruction that DCI includes is indicated with dynamic SFI The resource of the indicated PUCCH of the configuration information conflict of slot, i.e. PUCCH resource instruction does not fall within dynamic SFI instruction Slot ascender, mobile communication terminal still can with described in the matched downlink symbol transmission of the transfer resource of PUCCH PUCCH signal.

For the second sub-scene, since mobile communication terminal is both without semi-static SFI and dynamic SFI, because This, mobile communication terminal directly can transmit the PUCCH signal on the n-th+k slot.

In this scenario, it is the n-th+k slot that mobile communication terminal, which directly determines t-th of slot, so as to advise When not including timing indication field in model DCI, the determination of the slot for downstream feedback.

In addition, scene three can reduce effective saving system for configuring the signaling of SFI compared to scene one and scene two Expense.

In addition, being determined for the transmission of the reception of PDSCH signal and PUCCH signal using fixed in compared with the prior art When relationship, i.e., on n-th of slot s lot receive network side equipment send PDSCH signal after, that is, be fixed on the n-th+4 slot Upper transmission PUCCH signal, the present invention can change k value, so as to improve the flexibility ratio of t-th of slot configuration.

It should be noted that in practical applications, mobile communication terminal can be in conjunction with scene one and scene three to determine State t-th of slot；T-th of slot can also be determined in conjunction with scene two and scene three, it should be understood that, combining scene Two and scene three scene in, if mobile communication terminal only receives semi-static SFI, that is, receive semi-static SFI does not receive dynamic SFI, then mobile communication terminal can be determined described by the instruction of semi-static SFI T-th of slot, specific method of determination is identical with scene one, and to avoid repeating, details are not described herein.
