Embodiments herein is described in detail below in conjunction with attached drawing.

In 5GNR, the concept of UL subslot has been had been incorporated into, has included multiple UL subslot in a UL slot, The quantity for the UL subslot for including in one UL slot includes 2,4,7 or other quantity, each UL subslot In include one or more symbols.Such as shown in Fig. 1 and Fig. 2, Fig. 1 is the money in a UL slot including 4 UL subslot Source schematic diagram, Fig. 2 are the resource schematic diagram in a UL slot including 3 UL subslot.

It in fig. 1 and 2, include 14 symbols in a UL slot, the pattern of UL subslot is " 4343 " in Fig. 1, The i.e. before this UL subslot of 4 symbols, then be the UL subslot of 3 symbols, then be the subslot of 4 symbols, then be 3 The UL subslot of a symbol.By the UL subslot including two kinds of different lengths in so UL slot.It is shown in Fig. 2 The pattern of UL subslot is " 437 ", i.e., the UL subslot of 4 symbols before this, then be the UL subslot of 3 symbols, then It is the subslot of 7 symbols.It all include the UL subslot of different length in UL slot in display, Fig. 1 and Fig. 2.Certainly The division mode of UL subslot can also be in other situations, such as a UL slot comprising 2 UL in UL slot 14 symbols successively corresponding UL subslot of every 7 symbols, an or such as UL again in subslot, UL slot Comprising 14 symbols in 7 UL subslot, UL slot, successively every 2 symbols correspond to a UL subslot in slot, It that is include the identical UL subslot of multiple length in UL slot.Base station is that the UL subslot pattern of terminal configuration can be It is configured by high-level signaling.

UL slot is that terminal is used for transmission uplink information and uses, after introducing UL subslot, with UL solt couple The ascending resource configuration mode answered can not be suitable for UL subslot, therefore how distribute on corresponding for UL subslot Row resource is problem to be solved.

Fig. 3 is the flow chart that a kind of uplink transmission resource that an embodiment provides determines method, as shown in figure 3, this implementation The method that example provides includes the following steps.

Step S3010 configures PUCCH resource collection for upstream node and is combined.

Uplink transmission resource provided in this embodiment determines the base station equipment that method is applied in wireless communication system, referred to as Base station.Base station is that upstream node distributes various transfer resources, and sends various configuration informations to upstream node, so that uplink section Point determines the various measurements for transmitting used resource and required execution or transmission instruction.Upstream node includes terminal or any Using the equipment of uplink channel transmission information, in the following each embodiments of the application upstream node be terminal for say It is bright.

Various resources used in terminal transmission uplink information are required to be configured by base station, and base station makes according to resource With situation, the uplink transmission resource of various businesses data and control signaling is transmitted for terminal configuration.Introducing UL subslot Afterwards, UL subslot can be used for transmitting various ascending control informations (Uplink Control Information, UCI), packet HARQ-ACK information is included, and various UCI are carried in PUCCH and are transmitted, but original is configured by UL slot The method of salary distribution of PUCCH resource has not been suitable for for UL subslot service.Therefore in the present embodiment, base station needs for eventually UL slot used in end transmission PUCCH reconfigures PUCCH resource collection and is combined.

The division mode of UL subslot has a variety of situations in UL slot, such as shown in Fig. 1 and Fig. 2, different UL The division mode of subslot is different and makes UL subslot that may have different length, included in a UL slot The quantity of UL subslot is also indefinite.Therefore the PUCCH resource collection for terminal configuration, which is combined, needs to be suitable for different demarcation mode UL slot.One PUCCH resource collection includes one or more PUCCH resource set, a PUCCH resource set in being combined In include one or more PUCCH resources.PUCCH resource collection for terminal configuration is combined, and can be for each UL Subslot configures one-to-one PUCCH resource, UL subslot can also be grouped, be wrapped in every group of UL subslot One or more corresponding PUCCH resource collection of UL subslot, every group of UL subslot with same characteristic features are included to be combined.

Step S3020 determines upstream node in a uplink sub-slots according to preset rules in PUCCH resource collection is combined The PUCCH resource used.

After being configured with PUCCH resource collection for terminal and being combined, terminal is the PUCCH during usable PUCCH resource collection is combined Resource is transmitted on UL subslot, but due to PUCCH resource collection be combined in include multiple PUCCH resources, UL The division mode of subslot also has a case that different, therefore also needs between base station and terminal according to certain preset rules It determines each UL subslot specific PUCCH resource corresponding in PUCCH resource collection is combined, that is, determines in PUCCH The mode of PUCCH resource is selected in resource collection.

Base station and terminal can about be scheduled on PUCCH resource collection in advance and be combined used in the middle each UL subslot of selection The packet mode of the rule of PUCCH resource, the UL subslot in the UL solt used in the terminal determines, base station and terminal It can be during the PUCCH resource collection that terminal configures is combined in base station, be the same UL according to identical preset rules Subslot selects identical PUCCH resource, so as to be the information transmission realized on UL subslot.In addition, base station is also It can be after being configured with PUCCH resource collection for terminal and being combined, each UL subslot is in PUCCH resource in reconfiguration UL slot Collect PUCCH resource corresponding in being combined, then base station passes through high-level signaling for the pass corresponding with PUCCH resource UL subslot System's notice is to terminal.

Uplink transmission resource provided in this embodiment determines method, after configuring PUCCH resource collection for terminal and being combined, according to Preset rules determine the PUCCH resource that terminal is used in a uplink sub-slots in PUCCH resource collection is combined, and are the uplink period of the day from 11 p.m. to 1 a.m Gap has determined available uplink transmission resource, has taken into account signaling overheads and PUCCH resource flexibility ratio.

Base station is that the PUCCH resource collection of terminal configuration is combined, and can be configured according to different modes, it is however generally that, UL subslot can be grouped according to the feature of UL subslot in UL slot, be that every group of UL subslot configures phase With PUCCH resource collection be combined, multiple UL subslot in every group of UL subslot share during a PUCCH resource collection is combined PUCCH resource, during each UL subslot in every group of UL subslot is combined further according to certain mechanism from PUCCH resource collection PUCCH resource needed for selection.The PUCCH resource for being combined kind for each group UL subslot PUCCH resource collection configured can portion Divide or all identical.And for the UL subslot after grouping, the configuration mode that PUCCH resource collection is combined for example can be using such as Under any mode:

In one embodiment, the length of each uplink sub-slots in uplink sub-slots group is identical, that is, will be in UL slot UL subslot be grouped according to length, then for the identical UL subslot of every group of length configure one it is corresponding PUCCH resource collection is combined.Such as the UL slot that " 4343 " shown in FIG. 1 divide, length are that the UL subslot of 4 symbols can To be divided into one group, length is that the UL subslot of 3 symbols can be divided into one group, i.e., by first and third in UL slot A UL subslot points are one group, are one group by second and the 4th UL subslot points in UL slot.Each uplink The length of each uplink sub-slots in time slot group is identical, is conducive to distribute the length with uplink sub-slots for each uplink sub-slots group The PUCCH resource collection to match is spent to be combined.In addition, the identical UL subslot of length can also directly with a PUCCH resource Collection is combined correspondence, is grouped without the length further according to UL subslot to the UL subslot in UL slot.Such as base Standing is that UL subslot one PUCCH resource collection of configuration that length is 4 is combined, and base station is the UL subslot configuration that length is 3 One PUCCH resource collection is combined.Thus there are 2 PUCCH resource collection to be combined, respectively corresponds the UL of different length subslot.Here, it may include PUCCH resource set 0, PUCCH resource set 1, PUCCH money that a PUCCH resource collection, which is combined, Source set 2, first 1 or preceding multiple in PUCCH resource set 3.It can be and configured by high-level signaling (such as RRC signaling). Can be described as: all length is that the shared PUCCH resource collection of UL subslot of 4 symbols is combined.All length is 3 The UL subslot of symbol shares a PUCCH resource collection and is combined.For the UL subslot of different length, (such as length is 3 The UL subslot of symbol and 4 symbols) it corresponding PUCCH resource collection is respectively configured is combined.During two PUCCH resource collection are combined PUCCH resource or PUCCH resource set allow part or all of PUCCH resource identical, be conducive to economize on resources in this way.

In one embodiment, each uplink sub-slots in ascending time slot are according to the serial number in ascending time slot, order-assigned In at least two uplink sub-slots groups, that is, according to appearance of the UL subslot in UL slot sequentially by UL subslot Be assigned as several groups, wherein the quantity organized can it is determining according to preset rules or by base station with postponing notice terminal.Such as UL The group number of subslot is set as 2 by terminal, then the UL slot that " 4343 " divide as shown in Figure 1, it can will be in UL slot First and second UL subslot point is one group (respectively 4 symbol lengths and 3 symbol lengths), and by UL slot In third and the 4th UL subslot points be one group (respectively 4 symbol lengths and 3 symbol lengths).UL The group number of subslot can also be implied by terminal, such as group number implies the send-receive point equal to base station for terminal service The quantity of (Transmit-Receive Point, TRP), such as base station are terminal service using 2 TRP, then packet mode is still It is such as above-mentioned.

In one embodiment, each uplink sub-slots in ascending time slot are according to the serial number in ascending time slot, cross-assignment In at least two uplink sub-slots groups.In this configuration mode, also need first to determine the quantity of group, the quantity of group can be with According to preset rules it is determining or by base station with postponing notice terminal.Each UL subslot in UL slot is not sequence point It fits at least two UL subslot groups, but the serial number according to each UL subslot in UL solt, by each UL Subslot cross-assignment is in each UL subslot group.Such as: it is required that group number is P, group index i, i=0,1,2 ... P-1, Then in UL slot UL subslot ranking index be q, q=0,1,2 ... Q-1.Q is UL subslot total in UL slot Number.UL subslot index q in every group of UL subslot meets: i=q mod P.When group number is 2, this configuration mode Being equivalent to according to UL subslot the ranking index in UL slot is odd number or even number grouping；Group number can by base station configure or Imply.The group number of UL subslot can be implied by terminal, such as group number implies the send-receive equal to base station for terminal service The quantity of point (Transmit-Receive Point, TRP), such as base station are terminal service using 2 TRP, then are grouped into 2 Group.

In one embodiment, there are also another configuration mode, it includes N number of UL subslot in UL slot that base station, which configures, and Configuring UL subslot in UL slot to divide is M group, then for the UL subslot that preceding M0 UL subslot group includes in slot Number is ceil (N/M), and the number for the UL subslot that rear M1 UL subslot group includes in slot is floor (N/M).M0+ M1=M.N number of UL subslot is according to sequence from front to back in slot, the UL subslot for including according to each subslot group Number, correspondence belong in M subslot group.

In one embodiment, base station can pass through wireless heterogeneous networks (Radio Resource Control, RRC) signaling The packet mode of uplink sub-slots group in ascending time slot is sent to terminal.Base station sends uplink sub-slots in ascending time slot to terminal The packet mode of group include any of the above-described kind of packet mode or base station be the UL subsolt in UL solt determine other Packet mode, base station make grouping spirit to the packet mode that terminal sends uplink sub-slots group in ascending time slot by RRC signaling It is living, but need to occupy certain expense.

In one embodiment, the quantity of uplink sub-slots group is identical as the quantity of the TRP for terminal service in ascending time slot, Each uplink sub-slots group is corresponding with a TRP.In this way PUCCH transmission can be independently carried out in order to each TRP.For example, base station It is that a TRP configures corresponding PUCCH resource set group # for the PUCCH resource set group # of terminal configuration.Can be The corresponding control information resources set (CORESET) of a TRP or a CORESET group are configured, and is the volume of the CORESET Number or the CORESET group be numbered, as number be n.It configures simultaneously or arranges what the corresponding PUCCH resource collection of the TRP was combined Number is also n.Its corresponding PUCCH is determined according to the number of the number of the corresponding CORESET of TRP or the CORESET group Resource set is combined.For example, the corresponding PUCCH resource set group # of TRP equal to the corresponding CORESET of the TRP number or The number of CORESET group.When base station is terminal service using multiple TRP, the corresponding UL subslot of a TRP is configured Group.The corresponding one or more PUCCH resource collection of one UL subslot group are combined.For example, the corresponding UL subslot of difference TRP Group time domain is not overlapped.

Fig. 4 is the flow chart that another uplink transmission resource that an embodiment provides determines method, as shown in figure 4, this reality The method for applying example offer includes the following steps.

Step S4010 configures Physical Uplink Control Channel PUCCH resource collection for upstream node and is combined.

Step S4020 sends determining for the uplink sub-slots for being used to indicate upstream node transmission HARQ-ACK to upstream node When indicate information, and be used to indicate upstream node carrying UCI PUCCH resource PRI.

Various resources used in terminal transmission uplink information are required to be configured by base station, and base station makes according to resource With situation, the uplink transmission resource of various businesses data and control signaling is transmitted for terminal configuration.Base station is sent to terminal Business datum is carried in Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH), and to The various control signalings that terminal is sent are carried on Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH) in, it include various resources used in terminal transmission uplink information in the PDCCH that base station is sent to terminal Instruction information.After introducing UL subslot, UL subslot can be used for transmitting various ascending control information (Uplink Control Information, UCI), including HARQ-ACK information, and various UCI are carried in PUCCH and are transmitted, But the method for salary distribution of original PUCCH resource configured by UL slot has not been suitable for for UL subslot service.Therefore In the present embodiment, base station needs to reconfigure PUCCH resource collection for UL slot used in transmission PUCCH and be combined, wherein UL In slot include multiple UL subslot, PUCCH resource collection be combined in include multiple PUCCH resource set, each PUCCH resource It include multiple PUCCH resources in set.Base station can also be used to indicate terminal transmission HARQ- to terminal transmission by other means The timing of the uplink sub-slots of ACK indicates information, and is used to indicate the PRI of the PUCCH resource of terminal carrying UCI.

After being configured with PUCCH resource collection for terminal and being combined, base station sends the PDCCH, PDCCH of scheduling PDSCH to terminal In include be used to indicate terminal transmission HARQ-ACK uplink sub-slots timing instruction information, and be used to indicate terminal carrying The PUCCH resource of the PUCCH resource of UCI indexes (PUCCH Resource Index, PRI).

Step S4030 determines that upstream node determines the uplink sub-slots used according to timing instruction information, determines uplink section Point determines the PUCCH used according to uplink sub-slots group where the length of determining uplink sub-slots or the uplink sub-slots of determination Resource set is combined, and determines that upstream node is combined determining use from determining PUCCH resource collection according to the bit number of UCI to be transmitted PUCCH resource set, determine that upstream node determines that the PUCCH that uses is provided according to PRI from determining PUCCH resource set Source.

Be combined being configured with PUCCH resource collection for terminal, and by PDCCH to terminal have sent timing instruction information and After PRI, base station can determine terminal in a uplink according to above- mentioned information in the PUCCH resource collection configured for terminal is combined The PUCCH resource that sub-slots use.Firstly, when base station is terminal scheduling PDSCH, the timing that will be configured in corresponding PDCCH Instruction information is denoted as k1, further includes PRI value in PDCCH, base station determines the UL of terminal transmission HARQ-ACK according to k1 value The position subslot determines that corresponding PUCCH resource collection is combined according to UL subslot group belonging to UL subslot, then base It stands and determines that terminal is combined middle determination pair from determining PUCCH resource collection according to the bit number of UCI to be transmitted (comprising HARQ-ACK) The PUCCH resource set answered, last base station determines terminal, and according to PRI value, the determination from determining PUCCH resource set is corresponding PUCCH resource.Base station has determined that the PUCCH resource that terminal is used in a uplink sub-slots in this way.Since base station is by PUCCH Resource set is combined, timing instruction information and PRI have all been sent to terminal, then terminal can also determine often according to identical process The PUCCH resource that a uplink sub-slots use, then terminal and base station are for the money of PUCCH determined by identical UL subslot Source will be identical, therefore base station can receive the information of terminal transmission in determining PUCCH resource.It base station can not also be to UL Subslot is grouped, but according to the feature of UL subslot determine the UL subslot of same characteristic features corresponding to PUCCH Resource set is combined, such as determines that terminal determines that the UL subslot of equal length is corresponding according to the length of the UL subslot used One identical PUCCH resource collection is combined.

In one embodiment, when base station is terminal service using multiple TRP, the corresponding UL of a TRP is configured Subslot group, the quantity of UL subslot group is identical as the quantity of the TRP for terminal service in UL slot.For a UL Subslot group can configure one or more PUCCH resource collection and be combined.For example, can be based in a UL subslot group UL subslot length is that the corresponding PUCCH resource collection of each UL sublsot configuration is combined.In this case, base station determines Terminal is as follows in the mode for the PUCCH resource that a uplink sub-slots use:

In one embodiment, base station is terminal service using 2 TRP (being denoted as TRP0 and TRP1), and a UL slot is matched It is set to comprising 4 UL subslot, such as " 4343 " structure shown in FIG. 1, is then 2 by the UL subslot in UL slot points Group, for example, first " 4 " and second " 4 " belong to one group, number 0, first " 3 " and second " 3 " belong to one group, compile Number be 1.Staggeredly it is grouped.2 CORESET or CORESET groups, number 0,1 are configured for terminal.2 PUCCH are configured for terminal Resource set is combined, and number is 0 (for UL subslot group 0) and 1 (for UL subslot group 1) respectively.Based on above-mentioned It is assumed that example are as follows: base station by TRP0 be terminal transmission PDSCH0 when, it is assumed that selected number for 0 CORESET or CORESET group transmits the corresponding PDCCH of the PDSCH0, and base station will determine PUCCH resource used in terminal transmission HARQ-ACK 0 will be combined from PUCCH resource collection.Terminal also will detect the PDCCH in CORESET the or CORESET group that number is 0, To receive the PDSCH0, then terminal is that the PUCCH resource that the corresponding HARQ-ACK of the PDSCH0 is determined will come from PUCCH resource Collection is combined 0 (this is because to detect the PDSCH0 in CORESET the or CORESET group that number is 0 corresponding for terminal PDCCH is determined according to the PUCCH resource set group # of agreement and CORESET (group) number principle of identity).Then, base station Slot/subslot of the HARQ-ACK by transmission is determined by k1, and by UCI to be transmitted, (including HARQ-ACK also be can wrap Include other UCI information) bit number from having determined that PUCCH resource collection is combined the corresponding PUCCH resource set of middle selection, according to PRI determines the PUCCH resource used from the PUCCH resource set having determined.Here be actually CORESET or CORESET group and PUCCH resource set group establish binding relationship, for example, always default both number it is identical.

In one embodiment, UL slot/UL subslot is grouped, is every group of UL slot/UL subslot configuration one A PUCCH resource collection is combined, for example, the k1 in PDCCH can be indicated when PDSCH corresponding PDCCH is transmitted by TRP in base station One UL slot/UL subslot judges that the UL slot/UL subslot belongs to that UL slot/UL subslot group, Then it is corresponding to be combined the final PDSCH of middle determination for the determining corresponding PUCCH resource collection of UL slot/UL subslot group The PUCCH resource of HARQ-ACK transmission.It here is actually that UL slot/UL subslot group and PUCCH resource set group are established Binding relationship, for example, always default UL slot/UL subslot group number is with PUCCH resource set group number identical.

In one embodiment, for terminal configuration CORESET or CORESET group and UL slot/UL subslot group it Between establish binding relationship, for example, always default both group number it is identical.For example, TRP is by CORESET or CORESET group 0 UE transmits the PDCCH of scheduling PDSCH, then the corresponding HARQ-ACK of the PDSCH is used in UL slot/UL subslot group 0 Slot/subslot is transmitted, and the corresponding PUCCH resource of the HARQ-ACK is also possible to from UL slot/UL subslot group 0 Corresponding PUCCH resource collection is combined.

In one embodiment, when base station using multiple TRP is terminal service, for terminal configure different CORESET or CORESET group, the corresponding HARQ-ACK of PDSCH of the PDCCH scheduling of different CORESET or CORESET group transmission is different It is transmitted in UL subslot.For example, 2 TRP are terminal multiplexing, and configuring 2 CORESET or CORESET groups is UE, and number is 0 and 1, TRP0 the transmission PDCCH in CORESET the or CORESET group that number is 0 dispatch PDSCH0, and the PDSCH0 is corresponding The corresponding PUCCH resource of HARQ-ACK is in a UL subslot (for ease of description, being denoted as A)；TRP1 is 1 in number PDCCH is transmitted in CORESET or CORESET group dispatches PDSCH1, the corresponding PUCCH resource of the corresponding HARQ-ACK of the PDSCH1 In another UL subslot (for ease of description, being denoted as B, A and B not is same UL subslot).It is this in order to realize, base It stands and corresponds to k1 in PDCCH by corresponding to k1 in PDCCH and PDSCH1 in PDSCH0, reasonable value is configured, so that finally The corresponding HARQ-ACK of PDSCH0 and PDSCH1 is in different UL subslot.That is, terminal is undesirable, it is different The corresponding PUCCH resource of the corresponding HARQ-ACK of PDSCH of TRP transmission is in identical UL subslot.In order to enable PUCCH is provided Source transmission is more flexible, here, if base station is that the corresponding HARQ-ACK of PDSCH that multiple TRP are transmitted respectively is respectively right The PUCCH resource answered in identical UL subslot, then: it is different if 1) these PUCCH resource time domains are overlapped After the corresponding HARQ-ACK of PDSCH is cascaded, the PUCCH of the last one PDCCH instruction in the corresponding PDCCH of PDSCH It is transmitted in resource；If the corresponding HARQ-ACK of difference PDSCH exists alternatively, 2) these PUCCH resource time domains are not overlapped It is transmitted in respective PUCCH resource.

In one embodiment, base station is numbered using multiple TRP and establishes binding pass between UL slot/UL subslot group System, for example, the two number is identical.That is the corresponding HARQ-ACK of PDSCH of TRP0 transmission is at 0 pair of group of UL slot/UL subslot (UL subslot group can also become UL subslot, and this method is equally suitable for transmission in the UL slot/UL subslot answered With, such as most simply an i.e. UL subslot only includes a UL subslot).

In one embodiment, G1 PUCCH resource collection is configured for UE to be combined, and be every group of configuration index value.Configuration one UL slot includes G2 UL subslot, configures the index that a PUCCH resource collection is combined to configure each UL subslot. It is combined in this way, each UL subslot can correspond to a PUCCH resource collection, when HARQ-ACK is indicated on a certain UL When transmitting in subslot, terminal can be combined middle HARQ-ACK pairs of selection from the corresponding PUCCH resource collection of the UL sublsot The PUCCH resource answered.Here an identical PUCCH resource collection can be configured for different UL sublsot to be combined, especially When these UL subslot have equal length, this sample is conducive to saving signaling expense, will not reduce PUCCH resource distribution Quantity and flexibility ratio.

CORESET group (and TRP index) in the various embodiments described above, PUCCH resource collection is combined, UL subslot group, Corresponding relationship between UL subslot can be supported, and specifically used any corresponding relationship can be configured by base station. For example, the index of a CORESET or CORESET group can be combined correspondence with a PUCCH resource collection, it also can be with a UL Sublsot is corresponding, then specifically used any corresponding relationship, base station is determined by configuring.A kind of situation is, if default Above-mentioned corresponding relationship is one-to-one, then can be determined according to the TRP number or CORESET group number for terminal service Corresponding PUCCH resource collection is combined number.If PUCCH resource quantity is greater than TRP number or CORESET group number, base station energy Configure many-to-one corresponding relationship.

In the embodiment of the present application, UL subslot group can be a UL subslot, corresponding and UL subslot group The equally applicable UL subslot of mode.

Since original PUCCH resource is for used in UL slot transmission, PUCCH resource may be in the time domain Length it is longer, and after introducing UL subslot, since the length of a UL subslot is less than the length of UL slot, because This may cause the PUCCH resource collection for the distribution of UL subslot group be combined in the length of PUCCH resource be more than a UL The length of subslot.The application is that this situation provides three kinds of different processing methods, to solve the above problems.

In one embodiment, if the corresponding first PUCCH resource collection of the first uplink sub-slots group be combined in the first PUCCH The terminating symbol of resource is more than the terminating symbol of the first uplink sub-slots in the first uplink sub-slots group, then forbids instruction terminal to exist The first PUCCH resource is transmitted on first uplink sub-slots, or when terminal transmits the first PUCCH money on the first uplink sub-slots It is deleted when source in the first PUCCH resource more than the symbol of the first uplink sub-slots terminating symbol.Wherein above-mentioned deletion, which acts, includes It is truncated or destroys, be truncated and destroy as different processing methods, truncation indicates to be more than that the first uplink is sub from the first PUCCH resource Other symbols of first PUCCH resource are truncated for the position of time slot terminating symbol, and destroying expression will be more than in the first PUCCH resource The extra symbol of first uplink sub-slots terminating symbol is destroyed.It can be institute when base station is that terminal configuration PUCCH resource collection is combined Some UL subslot, which configures a PUCCH resource and integrates, to be combined or the mode according to above-described embodiment is UL subslot Multiple PUCCH resource collection are distributed to be combined.Base station and terminal agreement, correspond to the UL subslot of a specific length, in PUCCH If resource set be combined in the terminating symbol of a PUCCH resource have exceeded the terminating symbol of the UL subslot, base station is pressed It is handled according to following mode: forbidding indicating that the PUCCH resource is transmitted on the UL subslot for terminal in base station；Or, if should PUCCH resource is indicated on when transmitting in the UL subslot, beyond the UL subslot terminating symbol in the PUCCH resource Symbol is truncated/is struck off.It is combined for example, base station configures one or more PUCCH resource collection for terminal, including the first PUCCH Resource set is combined, and the corresponding first PUCCH resource collection of the first UL subslot group is combined, all UL in the first subslot group Subslot (subslot including different length) all using the first PUCCH resource collection be combined in PUCCH resource.For example, UL The division of UL subslot is as shown, for " 4343 " structure in slot, and when packet count is 2 groups, packet mode is sequential packet, It will include the UL subslot that length is 3 symbols and the UL that length is 4 symbols in so UL subslot group Subslot, then having in the first PUCCH resource collection is combined for the first UL subslot that a length is 3 symbols There may be the terminating symbols that the terminating symbol of PUCCH resource has exceeded the first UL subslot.Such as first PUCCH resource be 4 symbols, primary sign index are 0, symbolic number 4, then for the first UL subslot of 3 symbols, first PUCCH resource terminating symbol has exceeded the UL subslot terminating symbol and for the first UL subslot, can then use down The mode in face: base station is forbidden as the first UL subslot of 3 symbols, and instruction terminal transmits one in the first UL subslot A the first PUCCH resource more than the first UL subslot terminating symbol；Or base station and terminal are arranged, if base station indicates One the first PUCCH resource, and the first PUCCH resource terminating symbol has exceeded the terminating symbol of the first UL subslot, then Symbol in first PUCCH resource beyond the first UL subslot terminating symbol is truncated or is struck off, and does not transmit, only makes With in the first PUCCH resource without departing from the symbol transmission of the first UL subslot terminating symbol.This mode is configuration PUCCH money Source collection is combined simplest, and signaling overheads is the smallest.

In one embodiment, if the corresponding second PUCCH resource collection of the second uplink sub-slots group be combined in the 2nd PUCCH The beginning notation index of resource is more than the beginning notation index that the second uplink sub-slots allow in the second uplink sub-slots group, then prohibits Only instruction terminal transmits the second PUCCH resource on the second uplink sub-slots.Base station is that terminal configuration PUCCH resource collection is combined When, a PUCCH resource collection can be configured for all UL subslot be combined or the mode according to above-described embodiment Multiple PUCCH resource collection are distributed for UL subslot to be combined.Base station and terminal agreement, correspond to the UL of a specific length Subslot, if the beginning notation index of a PUCCH resource in PUCCH resource collection is combined has exceeded the UL The beginning notation index that subslot allows, base station are handled in following manner: forbidding indicating the PUCCH resource for terminal in base station It is transmitted on the UL subslot.Such as: base station configures one or more PUCCH resource collection for terminal and is combined, including second PUCCH resource collection is combined, and the corresponding second PUCCH resource collection of the 2nd UL subslot group is combined, in the 2nd UL subslot group All UL subslot (subslot including different length) all using the second PUCCH resource collection be combined in PUCCH provide Source.For example, in UL slot UL subslot division as shown, be " 4343 " structure, when packet count be 2 groups, packet mode For sequential packet, then will include length in a UL subslot group be the UL subslot of 3 symbols and length is 4 symbols Number UL subslot, then for a length be 4 the 2nd UL subslot of symbol, be combined in the second PUCCH resource collection In, it is possible to there are the beginning symbols that the beginning symbol of PUCCH resource has exceeded the permission of the 2nd UL subslot.Such as second PUCCH resource is 1 symbol, and primary sign index is 3, symbolic number 1, then for the 2nd UL subslot of 3 symbols For, the beginning notation index of permission is 0,1,2, it is clear that it is 3 that the second PUCCH resource, which starts notation index, have exceeded this second The beginning notation index that UL subslot allows then, can be by the way of following for the 2nd UL subslot: prohibiting base station It is only the 2nd UL subslot of 3 symbols, instruction terminal transmits one more than the 2nd UL in the 2nd UL subslot Second PUCCH resource of the beginning notation index that subslot allows.

In one embodiment, if the corresponding third PUCCH resource collection of third uplink sub-slots group be combined in the 3rd PUCCH The terminating symbol of resource is more than the terminating symbol of ascending time slot where third uplink sub-slots in third uplink sub-slots group, then prohibits Only instruction terminal transmits third PUCCH resource on third uplink sub-slots, or when terminal is uploaded in third uplink sub-slots Delete when defeated third PUCCH resource is more than ascending time slot terminating symbol where third uplink sub-slots group in third PUCCH resource Symbol.Wherein above-mentioned deletion movement includes truncation or destroys, and is truncated and destroys as different processing methods, and truncation is indicated from the In three PUCCH resources be more than third uplink sub-slots where ascending time slot terminating symbol position by third PUCCH resource its He is truncated symbol, and destroying indicates will to be more than ascending time slot terminating symbol where third uplink sub-slots in third PUCCH resource Extra symbol is destroyed.When base station is that terminal configuration PUCCH resource collection is combined, one can be configured for all UL subslot PUCCH resource, which integrates, to be combined or the mode according to above-described embodiment as UL subslot distributes multiple PUCCH resource set Group.Base station and terminal agreement, correspond to the UL subslot of a specific length, and base station is terminal from the PUCCH resource collection One PUCCH resource of instruction and the PUCCH resource are combined when transmitting in a UL subslot, the PUCCH money being instructed to Source terminating symbol allows the terminating symbol beyond the UL subslot, but the PUCCH resource terminating symbol does not allow beyond the UL The terminating symbol of UL slot where subslot.Such as: base station is that the one or more PUCCH resource collection of terminal configuration are combined, and is wrapped It includes third PUCCH resource collection to be combined, the 3rd UL subslot group corresponds to third PUCCH resource collection and is combined, the 3rd UL subslot All UL subslot (subslot including different length) are combined using third PUCCH resource collection in group.For example, UL The division of UL subslot is as shown, for " 4343 " structure in slot, and when packet count is 2 groups, packet mode is sequential packet, It will include the UL subslot that length is 3 symbols and the UL that length is 4 symbols in so UL subslot group Subslot, then be 3 the 3rd UL subslot of symbol for 1 length, in the third PUCCH resource collection of configuration is combined, The terminating symbol that there may be third PUCCH resource has exceeded the terminating symbol of the 3rd UL subslot.Such as the 3rd PUCCH Resource is 4 symbols, and primary sign index is 0, symbolic number 4, then transmitting for the 2nd, 4 UL subslot It, can be by the way of following when third PUCCH resource: for the 2nd UL subslot, the end mark of third PUCCH resource It number can exceed the terminating symbol of the 2nd UL subslot, but the end of UL slot where without departing from the 2nd UL subslot Symbol, so, third PUCCH resource can be indicated in the 2nd UL subslot and transmit.For the 4th UL subslot, The terminating symbol of three PUCCH resources can exceed the terminating symbol of the 4th UL subslot, but also have exceeded the 4th UL The terminating symbol of UL slot where subslot, then the 4th UL subslot is the 3rd UL subslot, so, third Processing of the PUCCH resource in the 4th UL subslot may is that base station forbids indicating the 3rd PUCCH in the 3rd UL It is transmitted in subslot.Alternatively, base station and terminal agreement, if base station indicates third PUCCH resource in the 3rd UL subslot Middle transmission, then the symbol beyond UL slot terminating symbol where the 3rd UL subslot in third PUCCH resource be truncated or It is struck off, does not transmit, only use in third PUCCH resource without departing from UL slot terminating symbol where the 3rd UL subslot Symbol transmission.

Fig. 5 is the flow chart that another uplink transmission resource that an embodiment provides determines method, as shown in figure 5, this reality The method for applying example offer includes the following steps.

Step S5010, the PUCCH resource collection for obtaining base station configuration are combined.

Uplink transmission resource provided in this embodiment determines the upstream node that method is applied in wireless communication system.Uplink Node sends various configuration informations according to base station and determines that the various measurements for transmitting used resource and required execution or transmission refer to It enables.Upstream node includes terminal or any equipment using uplink channel transmission information, in the following each embodiments of the application Upstream node be terminal for be illustrated.

Various resources used in terminal transmission uplink information are required to be configured by base station, and base station makes according to resource With situation, the uplink transmission resource of various businesses data and control signaling is transmitted for terminal configuration.Introducing UL subslot Afterwards, UL subslot can be used for transmitting various ascending control informations (Uplink Control Information, UCI), packet HARQ-ACK information is included, and various UCI are carried in PUCCH and are transmitted, but original is configured by UL slot The method of salary distribution of PUCCH resource has not been suitable for for UL subslot service.Therefore in the present embodiment, terminal needs to obtain Base station is that the PUCCH resource collection that UL slot used in terminal transmission PUCCH is reconfigured is combined.Terminal can be sent out from base station The PUCCH resource collection for any acquisition of information base station configuration sent is combined or base station and terminal can be pre-configured with PUCCH money Source collection is combined or base station and terminal mechanism can negotiate PUCCH resource collection and be combined through consultation.

The division mode of UL subslot has a variety of situations in UL slot, such as shown in Fig. 1 and Fig. 2, different UL The division mode of subslot is different and makes UL subslot that may have different length, included in a UL slot The quantity of UL subslot is also indefinite.Therefore base station is combined for the PUCCH resource collection of terminal configuration and needs to be suitable for different demarcation The UL slot of mode.One PUCCH resource collection includes one or more PUCCH resource set, a PUCCH resource in being combined It include one or more PUCCH resources in set.PUCCH resource collection for terminal configuration is combined, and can be for each UL Subslot configures one-to-one PUCCH resource, UL subslot can also be grouped, be wrapped in every group of UL subslot One or more corresponding PUCCH resource collection of UL subslot, every group of UL subslot with same characteristic features are included to be combined.

Step S5020 determines that upstream node makes in an ascending time slot according to preset rules in PUCCH resource collection is combined PUCCH resource.

Terminal is during that is, usable PUCCH resource collection is combined after the PUCCH resource collection that terminal configures is combined in acquisition base station PUCCH resource transmitted on UL subslot, but due to PUCCH resource collection be combined in include multiple PUCCH resources, UL The division mode of subslot also has a case that different, therefore also needs between base station and terminal according to certain preset rules It determines each UL subslot specific PUCCH resource corresponding in PUCCH resource collection is combined, that is, determines in PUCCH The mode of PUCCH resource is selected in resource collection.

Base station and terminal can about be scheduled on PUCCH resource collection in advance and be combined used in the middle each UL subslot of selection The packet mode of the rule of PUCCH resource, the UL subslot in the UL solt used in the terminal determines, base station and terminal It can be during the PUCCH resource collection that terminal configures is combined in base station, be the same UL according to identical preset rules Subslot selects identical PUCCH resource, so as to be the information transmission realized on UL subslot.In addition, base station is also It can be after being configured with PUCCH resource collection for terminal and being combined, each UL subslot is in PUCCH resource in reconfiguration UL slot Collect PUCCH resource corresponding in being combined, then terminal passes through the UL subslot and PUCCH that high-level signaling receives base station transmission The corresponding relationship of resource.

Uplink transmission resource provided in this embodiment determines method, after the PUCCH resource collection for obtaining base station configuration is combined, The PUCCH resource that terminal is used in an ascending time slot is determined in PUCCH resource collection is combined according to preset rules, is uplink Time slot has determined available uplink transmission resource, has taken into account signaling overheads and PUCCH resource flexibility ratio.

The base station that terminal obtains is that the PUCCH resource collection of terminal configuration is combined, and can be configured according to different modes, It is every group of UL in general, can be grouped UL subslot according to the feature of UL subslot in UL slot Subslot configures identical PUCCH resource collection and is combined, and multiple UL subslot in every group of UL subslot are one shared PUCCH resource collection be combined in PUCCH resource, each UL subslot in every group of UL subslot further according to certain mechanism from PUCCH resource needed for PUCCH resource collection is combined middle selection.PUCCH resource collection for each group UL subslot configuration is combined kind PUCCH resource can partly or entirely it is identical.And for the UL subslot after grouping, the configuration that PUCCH resource collection is combined Mode for example can be using following any mode:

The length of each uplink sub-slots in uplink sub-slots group is identical.Or each uplink sub-slots root in ascending time slot According to the serial number in ascending time slot, order-assigned is at least two uplink sub-slots groups.Or each uplink in ascending time slot Time slot is according to the serial number in ascending time slot, and cross-assignment is at least two uplink sub-slots groups.Or it is connect by RRC signaling Receive the packet mode that base station sends uplink sub-slots group in ascending time slot.In ascending time slot the quantity of uplink sub-slots group with for eventually Hold the quantity of the TRP of service identical, each uplink sub-slots group is corresponding with a TRP.The above-mentioned various methods of salary distribution are preceding It states in embodiment and is described in detail, details are not described herein again.

Fig. 6 is the flow chart that another uplink transmission resource that an embodiment provides determines method, as shown in fig. 6, this reality The method for applying example offer includes the following steps.

Step S6010, the PUCCH resource collection for obtaining base station configuration are combined.

Step S6020 receives the timing instruction information for being used to indicate the uplink sub-slots of upstream node transmission HARQ-ACK, And it is used to indicate the PRI of the PUCCH resource of upstream node carrying UCI.

Step S6030 determines the uplink sub-slots that upstream node uses according to timing instruction information, true according to upstream node Uplink sub-slots group where the length of fixed uplink sub-slots or the uplink sub-slots of determination determines the PUCCH that upstream node uses Resource set is combined, and is combined determining uplink from the PUCCH resource collection that terminal determines according to the bit number of upstream node UCI to be transmitted The PUCCH resource set that node uses determines that upstream node makes according to PRI from the PUCCH resource set that upstream node determines PUCCH resource.

It is combined obtaining the PUCCH resource collection that base station is terminal configuration, and is sent by PDCCH reception to base station to terminal Timing instruction information and PRI after, terminal can be according to above- mentioned information in the PUCCH resource collection configured for terminal is combined Determine the PUCCH resource used in a uplink sub-slots.Terminal receives the PDCCH for dispatching PDSCH first, from the PDCCH Obtain PDSCH to HARQ-ACK timing instruction information (being denoted as k1) and PRI.Terminal determines the HARQ- of the PDSCH according to k1 The position subslot of ACK transmission in the future, determines a corresponding PUCCH resource according to the length (symbolic number) of this subslot Collection is combined.Then terminal is according to the bit number of UCI to be transmitted (including the HARQ-ACK information) from determining PUCCH resource Collection is combined the corresponding PUCCH resource set of middle determination.According to PRI value, determination is corresponding from determining PUCCH resource set PUCCH resource.Since PUCCH resource collection is combined, timing instruction information and PRI are all that base station is sent to terminal, then base station The PUCCH resource that terminal is used in each uplink sub-slots can also be determined according to identical process, then terminal and base station needle Will be identical to PUCCH resource determined by identical UL subslot, therefore base station can receive in determining PUCCH resource The information that terminal is sent.Each UL subslot can also be determined identical without grouping according to the feature of UL subslot PUCCH resource collection corresponding to the UL subslot of feature is combined, such as determines terminal according to the length of the UL subslot used It spends and determines that the corresponding identical PUCCH resource collection of the UL subslot of equal length is combined.

Uplink transmission resource provided in this embodiment determines that method is applied to uplink transmission resource shown in embodiment illustrated in fig. 4 Determine the terminal side in method, uplink transmission resource provided in this embodiment determines the implementing principle and technical effect class of method Seemingly, details are not described herein again.

In one embodiment, when base station is terminal service using multiple TRP, the corresponding UL of a TRP is configured Subslot group, the quantity of UL subslot group is identical as the quantity of the TRP for terminal service in UL slot.In such case Under, the mode of the determining PUCCH resource used in a uplink sub-slots of terminal is as follows:

When multiple TRP are terminal service, terminal transmits the volume of the corresponding CORESET of the corresponding PDCCH of PDSCH according to TRP Number or the number of CORESET group determine that the corresponding PUCCH resource of the corresponding HARQ-ACK of the PDSCH that transmits is corresponding in the TRP PUCCH resource set is combined from which PUCCH resource collection.Such as, it is assumed here that having 2 TRP is terminal service, is matched for terminal It has set two PUCCH resource collection to be combined, number is 0 and 1.2 CORESET or CORESET groups, number 0 are configured with for terminal With 1.TRP0 is the CORESET group that the CORESET or number that terminal is 0 by number are 0, PDSCH0 is transmitted, then terminal Determine that the PUCCH resource of the corresponding HARQ-ACK of PDSCH0 will eventually be combined 0 from PUCCH resource collection；TRP1 is logical for terminal The CORESET that number is 1 or the CORESET group that number is 1 are crossed, PDSCH1 is transmitted, then terminal determines that PDSCH1 is corresponding The PUCCH resource of HARQ-ACK will eventually be combined 1 from PUCCH resource collection.Here TRP select that CORESET or CORESET group transmits a PDSCH, is configuration or agreement, or do not constrain, is independently selected by TRP, and same TRP is transmitted When different PDSCH, different CORESET or CORESET groups can choose.In addition, when being at that time terminal service with multiple TRP, The identical mode of processing mode of base station carries out respective handling when can also use aforementioned more TRP as terminal service.

In one embodiment, if the corresponding first PUCCH resource collection of the first uplink sub-slots group be combined in the first PUCCH The terminating symbol of resource is more than the terminating symbol of the first uplink sub-slots in the first uplink sub-slots group, then does not expect base station instruction Terminal transmits the first PUCCH resource on the first uplink sub-slots, or when terminal transmits first on the first uplink sub-slots It is deleted when PUCCH resource in the first PUCCH resource more than the symbol of the first uplink sub-slots terminating symbol.Wherein above-mentioned deletion is dynamic Make to include truncation or destroy, be truncated and destroy as different processing methods, truncation is indicated from the first PUCCH resource more than first Other symbols of first PUCCH resource are truncated for the position of uplink sub-slots terminating symbol, destroy expression for the first PUCCH resource In destroyed more than the extra symbol of the first uplink sub-slots terminating symbol.It, can when base station is that terminal configuration PUCCH resource collection is combined Think that all UL subslot configures a PUCCH resource and integrates to be combined or the mode according to above-described embodiment is UL Subslot distributes multiple PUCCH resource collection and is combined.Base station and terminal agreement, correspond to the UL subslot of a specific length, If the terminating symbol of a PUCCH resource in PUCCH resource collection is combined has exceeded the terminating symbol of the UL subslot, Terminal is handled in following manner: terminal is undesirable, and base station indicates the corresponding PUCCH money of the corresponding HARQ-ACK of a PDSCH Source is the PUCCH resource of 4 symbols, because PUCCH resource terminating symbol can exceed the terminating symbol of the UL subslot； Or, exceeding the UL subslot in the PUCCH resource if the PUCCH resource is indicated on when transmitting in the UL subslot The symbol of terminating symbol is truncated/is struck off.It is combined for example, base station configures one or more PUCCH resource collection for terminal, including First PUCCH resource collection is combined, and the corresponding first PUCCH resource collection of the first UL subslot group is combined, in the first subslot group All UL subslot (subslot including different length) all using the first PUCCH resource collection be combined in PUCCH provide Source.For example, in UL slot UL subslot division as shown, be " 4343 " structure, when packet count be 2 groups, packet mode For sequential packet, then will include length in a UL subslot group be the UL subslot of 3 symbols and length is 4 symbols Number UL subslot, then for a length be 3 symbols the first UL subslot, in the first PUCCH resource set In group, it is possible to which there are the terminating symbols that the terminating symbol of PUCCH resource has exceeded the first UL subslot.Such as first PUCCH resource is 4 symbols, and primary sign index is 0, symbolic number 4, then for the first UL subslot of 3 symbols For, the first PUCCH resource terminating symbol has exceeded the UL subslot terminating symbol then, can for the first UL subslot By the way of following: terminal is undesirable, and base station indicates that the corresponding PUCCH resource of the corresponding HARQ-ACK of a PDSCH is First PUCCH resource of 4 symbols, because the first PUCCH resource terminating symbol can exceed the end of the first UL subslot Symbol；Or base station and terminal are arranged, if base station indicates first PUCCH resource, and the first PUCCH resource end mark The terminating symbol of the first UL subslot number is had exceeded, then terminating in the first PUCCH resource beyond the first UL subslot The symbol of symbol is truncated or is struck off, and does not transmit, and only uses in the first PUCCH resource and ties without departing from the first UL subslot The symbol transmission of beam symbol.It is simplest that this mode is that configuration PUCCH resource collection is combined, and signaling overheads is the smallest.

In one embodiment, if the corresponding second PUCCH resource collection of the second uplink sub-slots group be combined in the 2nd PUCCH The beginning notation index of resource is more than the beginning notation index that the second uplink sub-slots allow in the second uplink sub-slots group, then not It is expected that base station instruction terminal transmits the second PUCCH resource on the second uplink sub-slots.Base station is that terminal configures PUCCH resource collection When being combined, a PUCCH resource collection can be configured for all UL subslot and be combined or according to above-described embodiment Mode is that the multiple PUCCH resource collection of UL subslot distribution are combined.Base station and terminal agreement, correspond to the UL of a specific length Subslot, if the terminating symbol of a PUCCH resource in PUCCH resource collection is combined has exceeded the UL subslot's Terminating symbol, terminal are handled in following manner: terminal is undesirable, and base station indicates that the corresponding HARQ-ACK of a PDSCH is corresponding PUCCH resource be 4 symbols PUCCH resource because PUCCH resource starts notation index and can exceed the UL subslot The beginning notation index of permission.Such as: base station configures one or more PUCCH resource collection for terminal and is combined, including the 2nd PUCCH Resource set is combined, and the corresponding second PUCCH resource collection of the 2nd UL subslot group is combined, all in the 2nd UL subslot group UL subslot (subslot including different length) all using the second PUCCH resource collection be combined in PUCCH resource.For example, The division of UL subslot is as shown, be " 4343 " structure, when packet count is 2 groups, packet mode is sequence point in UL slot Group, then will include the UL subslot that length is 3 symbols and the UL that length is 4 symbols in a UL subslot group Subslot, then being 4 the 2nd UL subslot of symbol for a length, in the second PUCCH resource collection is combined, having can Can exist PUCCH resource beginning symbol have exceeded the 2nd UL subslot permission beginning symbol.Such as the 2nd PUCCH money Source is 1 symbol, and primary sign index is 3, symbolic number 1, then permitting for the 2nd UL subslot of 3 symbols Perhaps beginning notation index is 0,1,2, it is clear that it is 3 that the second PUCCH resource, which starts notation index, has exceeded the 2nd UL The beginning notation index that subslot allows then, can be by the way of following for the 2nd UL subslot: terminal not phase It hopes, base station indicates that the corresponding PUCCH resource of the corresponding HARQ-ACK of a PDSCH is the second PUCCH resource of 4 symbols, Because the second PUCCH resource starts the beginning notation index that notation index can allow beyond the 2nd UL subslot.

In one embodiment, if the corresponding third PUCCH resource collection of third uplink sub-slots group be combined in the 3rd PUCCH The terminating symbol of resource is more than the terminating symbol of sub-frame of uplink where third uplink sub-slots in third uplink sub-slots group, then not It is expected that base station instruction terminal transmits third PUCCH resource on third uplink sub-slots, or when terminal is in the third uplink period of the day from 11 p.m. to 1 a.m The symbol in third PUCCH resource more than third uplink sub-slots group terminating symbol is deleted when transmitting third PUCCH resource in gap. Wherein above-mentioned deletion movement includes truncation or destroys, and is truncated and destroys as different processing methods, and truncation is indicated from the first PUCCH Other symbols of the first PUCCH resource are truncated more than the position of the first uplink sub-slots terminating symbol in resource, destroy expression Extra symbol in first PUCCH resource more than the first uplink sub-slots terminating symbol is destroyed.Base station is that terminal configures PUCCH When resource set is combined, a PUCCH resource collection can be configured for all UL subslot and be combined or according to above-described embodiment The mode is that the multiple PUCCH resource collection of UL subslot distribution are combined.Base station and terminal agreement, from the PUCCH resource Integrate in being combined as terminal instruction a PUCCH resource transmitted in the UL subslot when, the PUCCH resource terminating symbol permit Perhaps exceed the terminating symbol of the UL subslot, but terminal does not expect the terminating symbol of the PUCCH resource beyond the UL The terminating symbol of UL slot where subslot.Such as: base station is that the one or more PUCCH resource collection of terminal configuration are combined, It is combined including third PUCCH resource collection, the 3rd UL subslot group corresponds to third PUCCH resource collection and is combined, the 3rd UL All UL subslot (subslot including different length) are combined using third PUCCH resource collection in subslot group. For example, the division of UL subslot is as shown, be " 4343 " structure, when packet count is 2 groups, packet mode is in UL slot Sequential packet, then will include length in a UL subslot group be the UL subslot of 3 symbols and length is 4 symbols UL subslot, then for 1 length be 3 the 3rd UL subslot of symbol, in the third PUCCH resource set of configuration In group, it is possible to which there are the terminating symbols that the terminating symbol of third PUCCH resource has exceeded the 3rd UL subslot.Such as third PUCCH resource is 4 symbols, and primary sign index is 0, symbolic number 4, then for the 2nd, 4 UL subslot, In It, can be by the way of following: for the 2nd UL subslot, the knot of third PUCCH resource when transmitting third PUCCH resource Beam symbol can exceed the terminating symbol of the 2nd UL subslot, but UL slot where without departing from the 2nd UL subslot Terminating symbol, so, third PUCCH resource can be indicated in the 2nd UL subslot and transmit.For the 4th UL Subslot, the terminating symbol of third PUCCH resource can exceed the terminating symbol of the 4th UL subslot, but also have exceeded the The terminating symbol of UL slot where 4 UL subslot, then the 4th UL subslot is the 3rd UL subslot, institute With processing of the third PUCCH resource in the 4th UL subslot may is that terminal is undesirable, and base station indicates the 3rd PUCCH Resource is transmitted in the 3rd UL subslot.Alternatively, base station and terminal agreement, if base station indicates third, PUCCH resource exists It is transmitted in 3rd UL subslot, then beyond UL slot terminating symbol where the 3rd UL subslot in third PUCCH resource Symbol be truncated or be struck off, do not transmit, only use in third PUCCH resource without departing from UL where the 3rd UL subslot The symbol transmission of slot terminating symbol.

It is whole that method, which carries out, to be determined to uplink transmission resource provided by the embodiments of the present application with several specific embodiments below Body explanation.

Embodiment 1

It is assumed that base station is that the UL subslot pattern of terminal (hereinafter referred to as UE) configuration is in a UL slot " 4343 " (illustrate, when other UL subslot patterns, principle is identical) that this can be high-level signaling by taking " 4343 " as an example here Configuration, when all high-level signalings do not update, the pattern of UL subslot is such in all UL slot.About " 4343 " Meaning is explained as follows: the UL subslot for including in UL slot is respectively as follows: the UL subslot of 4 symbols before this, then is 3 The UL subslot of symbol, then be the UL subslot of 4 symbols, then be the UL subslot of 3 symbols.When other patterns, Principle is identical.

Base station is that length (symbolic number) configuration when UE configures PUCCH resource set based on UL subslot is corresponding PUCCH resource and PUCCH resource set.

Base station is that UE is that UL subslot one PUCCH resource collection of configuration that length is 4 is combined (for convenience here PUCCH resource collection is denoted as to be combined 1), base station be UE be length be 3 UL subslot configure a PUCCH resource collection be combined (for Description is convenient to be denoted as PUCCH resource collection here and is combined 2).Thus there are 2 PUCCH resource collection to be combined, respectively corresponds difference The UL subslot of length.Here, for example, it may include PUCCH resource set 0, PUCCH money that a PUCCH resource collection, which is combined, Source set 1, PUCCH resource set 2, first 1 or preceding multiple in PUCCH resource set 3.Here it can be and pass through high-level signaling (such as RRC signaling) configuration.Here also can be described as: all length is the shared PUCCH money of UL subslot of 4 symbols Source collection is combined.All length is that the shared PUCCH resource collection of UL subslot of 3 symbols is combined.It here, is different length UL subslot (such as length be 3 symbols and 4 symbols UL subslot) corresponding PUCCH resource collection is respectively configured It is combined.Two PUCCH resource collection be combined in PUCCH resource or PUCCH resource set allow part or all of PUCCH resource phase Together.Be conducive to economize on resources in this way.

According to above-mentioned mechanism, more specific base station and the behavior of UE are had below, to support above-mentioned PUCCH resource collection Close configuration.

In the side UE, UE determines the rule of a PUCCH resource are as follows: UE receives the PDCCH of scheduling PDSCH, from the PDCCH PDSCH to HARQ-ACK timing instruction information is obtained (to be denoted as k1, indicate letter based on the timing that UL slot/UL subslot is determined Breath, according to actual disposition selection UL slot or the UL subslot that k1 is indicated at this time, k1 indicates UL in the present embodiment Subslot) and PUCCH resource indicates information (PRI).It is determined according to k1, the UL of the HARQ-ACK of PDSCH transmission in the future The position subslot determines that a corresponding PUCCH resource collection is combined according to the length (symbolic number) of this UL subslot.Root According to the bit number of ascending control information UCI to be transmitted (including the HARQ-ACK information) from determining PUCCH resource set Corresponding PUCCH resource set is determined in group.Corresponding PUCCH is determined from determining PUCCH resource set according to PRI value Resource.

In base station side, the PUCCH resource of UE transmission is determined using identical rule, to receive in the PUCCH resource The UCI information of UE transmission.When base station is that UE dispatches PDSCH, k1 and PRI value is configured in corresponding PDCCH, according to k1 value The position UL subslot for determining UE transmission HARQ-ACK, determines the PUCCH resource that UE is used according to the length of UL subslot Collection is combined, and is combined middle determination from determining PUCCH resource collection according to the bit number of UE UCI to be transmitted (including the HARQ-ACK) Corresponding PUCCH resource set determines corresponding PUCCH resource according to PRI value from determining PUCCH resource set.

Embodiment 2

Base station is UE, and the UL subslot in UL slot is grouped, and the UL subslot for being every group configures one or more PUCCH resource collection is combined.UL subslot in group shares identical one or more PUCCH resource collection and is combined.

Packet mode about UL subslot in UL slot can be following one kind:

Mode 1, UL subslot points of equal length are one group；For example, in embodiment 1 under the pattern of " 4343 ", UL It is one group that length, which is the UL subslot of 4 symbols, in slot, and length is that the UL subslot of 3 symbols is one group.

UL subslot in UL slot is divided into multiple groups by mode 2 in sequence, group number can be configured by base station or Person implies, and such as organizes number and implies the quantity for being equal to TRP；Such as when being divided into 2 groups in embodiment 1 under the pattern of " 4343 ", then UL slot In preceding 2 UL subslot be one group (respectively 4 symbols and 3 symbol lengths), in UL slot after 2 UL subslot It is one group (respectively 4 symbols and 3 symbol lengths).

Mode 3, according to UL subslot, ranking index is odd number or even number grouping in UL slot；Group number can be by base station Configuration implies, and such as organizes the number quantity in secret equal to TRP.The case where this is suitble to 2 groups.

Mode 4, according to the group number of UL subslot, successively by UL subslot ranking index cross-packet in slot.Example Such as, it is desirable that group number is P, group index i, i=0,1,2 ... P-1, then the ranking index of UL subslot is q, q in UL slot =0,1,2 ... Q-1.Q is UL subslot number total in UL slot.UL subslot index q in every group of UL subslot Meet: i=q mod P.

Mode 5, it includes N number of UL subslot in slot that base station, which configures, and configuring UL subslot in slot to divide is M group, The number for the UL subslot that then preceding M0 UL subslot group includes in UL slot is ceil (N/M), rear M1 UL in slot The number for the UL subslot that subslot group includes is floor (N/M).M0+M1=M.N number of UL subslot is pressed in UL slot According to sequence from front to back, the UL subslot number for including according to each UL subslot group, correspondence belongs to M UL In subslot group.

Mode 6, it is one group that base station, which configures those UL subslot by RRC signaling,；It is obvious also possible to be configured by RRC Carry out implementation 1, mode 2, mode 3, the UL subslot group result in mode 4 and mode 5.RRC signaling configuration is most clever Living, but have expense.

Here, one group of UL subslot is also referred to as a UL subslot group.Optionally, the number of UL subslot grouping It can be equal to the number of UE configuration/service TRP, such as current TRP is usually 2.For the corresponding UL of each TRP Subslot group (UL subslot group may include one or more UL subslot).

One or more PUCCH resource collection can be configured for a UL subslot group to be combined.For example, in a UL It can be that the corresponding PUCCH resource collection of each UL sublsot configuration is combined based on UL subslot length in subslot group. For example, the UL subslot of equal length configures identical PUCCH resource collection and is combined in UL subslot group.

It is a UE service in conjunction with multiple TRP, mode below can be considered.

When multiple TRP are that UE is serviced, configure the corresponding PUCCH resource collection of a TRP and be combined, in order to which each TRP is only It is vertical to carry out PUCCH transmission.For example, configuring its corresponding PUCCH for the PUCCH resource set group # of UE configuration for a TRP Resource collection group #.It can be the corresponding control information resources set (CORESET) of one TRP of configuration or one CORESET group, and be numbered for the number or the CORESET group of the CORESET, it is n as numbered, while configuring or arranging to be somebody's turn to do The corresponding PUCCH resource of TRP integrates the number being combined also as n.I.e. according to the number or the CORESET of the corresponding CORESET of TRP The number of group determines that its corresponding PUCCH resource collection is combined, and is somebody's turn to do for example, the corresponding PUCCH resource set group # of TRP is equal to The number of the corresponding CORESET of TRP or the number of CORESET group.

For UE, when multiple TRP are that UE is serviced, UE transmits the corresponding CORESET's of the corresponding PDCCH of PDSCH according to TRP The number of number or CORESET group determines the corresponding PUCCH resource pair of the corresponding HARQ-ACK of the PDSCH transmitted in the TRP PUCCH resource set is answered to be combined from which PUCCH resource collection.Such as, it is assumed here that there are 2 TRP for UE service, is configured for UE Two PUCCH resource collection are combined, and number is 0 and 1.2 CORESET or CORESET groups are configured with for UE, number is 0 and 1. TRP0 is the CORESET group that the CORESET or number that UE is 0 by number are 0, transmits PDSCH0, then UE is determined The PUCCH resource of the corresponding HARQ-ACK of PDSCH0 will eventually be combined 0 from PUCCH resource collection, and (detailed method of determination is shown in Above and the description in embodiment 1)；TRP1 is the CORESET group that the CORESET or number that UE is 1 by number are 1, is passed Defeated PDSCH1, then UE determines that the PUCCH resource of the corresponding HARQ-ACK of PDSCH1 will eventually come from PUCCH resource set Group 1.Here TRP selects that CORESET or CORESET group to transmit a PDSCH, is configuration or agreement, or do not constrain, It is independently selected by TRP, and when the same TRP different PDSCH of transmission, can choose different CORESET or CORESET groups.

For base station and similar principle, adaptation is only done.

When multiple TRP are that UE is serviced, the corresponding UL subslot group of a TRP is configured.One UL subslot group pair One or more PUCCH resource collection are answered to be combined.For example, the corresponding UL subslot group time domain of difference TRP be not overlapped (note: this In UL subslot group can also become UL subslot, this method is equally applicable, for example, most simply i.e. a UL Subslot only includes a UL subslot, i.e. the corresponding UL subslot of a TRP).

One typical example, 2 TRP (being denoted as TRP0 and TRP1) are UE service, and a UL slot is configured to contain UL subslot point is then 2 groups in UL slot by 4 UL subslot, such as " 4343 " structure, for example, first " 4 " and Belong to one group for second " 4 ", number 0, first " 3 " and second " 3 " belong to one group, number 1.Staggeredly it is grouped.For UE configures 2 CORESET or CORESET groups, number 0,1.It configures 2 PUCCH resource collection for UE to be combined, number is 0 respectively (for UL subslot group 0) and 1 (for UL subslot group 1).Based on above-mentioned it is assumed that example are as follows: TRP0 UE When transmitting PDSCH0, it is assumed that number has been selected to transmit the PDSCH0 corresponding PDCCH, UE for 0 CORESET or CORESET group Side detects the PDCCH in CORESET the or CORESET group that number is 0, to receive the PDSCH0, then UE is to be somebody's turn to do The PUCCH resource that the corresponding HARQ-ACK of PDSCH0 is determined will be combined 0 (this is because UE is 0 in number from PUCCH resource collection CORESET or CORESET group in detect the corresponding PDCCH of the PDSCH0, volume is combined according to the PUCCH resource collection of agreement Number with CORESET (group) number principle of identity determine).Further, UE can obtain k1 and PRI from the PDCCH, pass through k1 Determine UL slot/UL subslot of the HARQ-ACK by transmission, by UCI to be transmitted (including the HARQ-ACK, Also may include other UCI information) bit number is from having determined that PUCCH resource collection is combined the corresponding PUCCH resource collection of middle selection It closes, determines the PUCCH resource used from the PUCCH resource set having determined according to PRI.It here is actually CORESET Or CORESET group and PUCCH resource set group establish binding relationship, such as always default both number it is identical.

It is also possible to for UL slot/UL subslot being grouped, is that every group of UL slot/UL subslot configures one PUCCH resource collection is combined, for example, the k1 in PDCCH can be indicated to a UL when TRP transmission PDSCH corresponding PDCCH Slot/UL subslot judges that the ULslot/UL subslot belongs to that UL slot/UL subslot group, then determines The corresponding PUCCH resource collection of UL slot/UL subslot group be combined the final corresponding HARQ- of the PDSCH of middle determination The PUCCH resource of ACK transmission.It here is actually that UL slot/UL subslot group and PUCCH resource set group are established and tied up Relationship is determined, for example, always default UL slot/UL subslot group number is identical with PUCCH resource set group number.

It is also possible to establish between CORESET the or CORESET group and UL slot/UL subslot group that configure for UE Binding relationship, for example, always the group number of both defaults is identical.For example, TRP is UE transmission by CORESET or CORESET group 0 The PDCCH of scheduling PDSCH, then the corresponding HARQ-ACK of the PDSCH uses the slot/UL in UL slot/subslot group 0 Subslot is transmitted, and the corresponding PUCCH resource of the HARQ-ACK is also possible to from the correspondence of UL slot/UL subslot group 0 PUCCH resource collection be combined.

When to be also possible to multiple TRP be UE service, different CORESET or CORESET groups is configured for UE, it is different The corresponding HARQ-ACK of PDSCH of the PDCCH scheduling of CORESET or CORESET group transmission is passed in different UL subslot It is defeated.For example, 2 TRP are UE multiplexing, and configuring 2 CORESET or CORESET groups is UE, and number is 0 and 1, and TRP0 is being numbered PDSCH0 is dispatched to transmit PDCCH in 0 CORESET or CORESET group, the corresponding HARQ-ACK of the PDSCH0 is corresponding PUCCH resource is in a UL subslot (for ease of description, being denoted as A)；The CORESET or CORESET that TRP1 is 1 in number PDCCH is transmitted in group and dispatches PDSCH1, and the corresponding PUCCH resource of the corresponding HARQ-ACK of the PDSCH1 is in another UL Subslot (for ease of description, being denoted as B, A and B not is same UL subslot).It is this in order to realize, base station by PDSCH0 corresponds to k1 in PDCCH and PDSCH1 and corresponds to k1 in PDCCH, configures reasonable value so that final PDSCH0 and The corresponding HARQ-ACK of PDSCH1 is in different UL subslot.That is, UE is undesirable, different TRP transmission For the corresponding PUCCH resource of the corresponding HARQ-ACK of PDSCH in identical UL subslot, this is simplest mode.In order to make It is more flexible to obtain PUCCH resource transmission, here, if base station is the corresponding HARQ- of PDSCH that multiple TRP are transmitted respectively The corresponding PUCCH resource of ACK in identical UL subslot, then: if 1) these PUCCH resource time domains be overlapped, After then the corresponding HARQ-ACK of difference PDSCH is cascaded, the last one PDCCH refers in the corresponding PDCCH of the PDSCH It is transmitted in the PUCCH resource shown；If difference PDSCH is corresponding alternatively, 2) these PUCCH resource time domains are not overlapped HARQ-ACK is transmitted in respective PUCCH resource.

It is also possible to establish binding relationship between TRP number and UL slot/UL subslot group, for example, the two is numbered It is identical.That is the corresponding HARQ-ACK of PDSCH of TRP0 transmission is in the corresponding UL slot/UL of UL slot/UL subslot group 0 (UL subslot group can also become UL subslot, and this method is equally applicable, such as most simply i.e. for transmission in subslot One UL subslot only includes a UL subslot).

It is also possible to be combined for UE G1 PUCCH resource collection of configuration, and is every group of configuration index value.Configure a UL Slot includes G2 UL subslot, configures the index that a PUCCH resource collection is combined to configure each UL subslot.This Sample, each UL subslot can correspond to a PUCCH resource collection and be combined, when HARQ-ACK is indicated on a certain UL subslot When middle transmission, it is corresponding that UE can be combined the middle selection HARQ-ACK from the corresponding PUCCH resource collection of the UL sublsot PUCCH resource.Here an identical PUCCH resource collection can be configured for different UL sublsot be combined, especially these When UL subslot has equal length, this sample is conducive to saving signaling expense, will not reduce PUCCH resource quantity allotted And flexibility ratio.

CORESET group (and TRP index) in above-mentioned example, PUCCH resource collection is combined, UL subslot group, UL Corresponding relationship between subslot can be supported, and specifically used any corresponding relationship can be configured by base station.Example Such as, the index of a CORESET or CORESET group can be combined correspondence with a PUCCH resource collection, also can be with a UL Sublsot is corresponding, then specifically used any corresponding relationship, base station is determined by configuring.A kind of simplification is, if default Above-mentioned corresponding relationship is one-to-one, then can be according to the TRP number or CORESET group number serviced for UE, determining pair The PUCCH resource collection answered is combined number.If PUCCH resource quantity is greater than TRP number or CORESET group number, base station and can match Set many-to-one corresponding relationship.

Above-mentioned UL subslot group can be a UL subslot, corresponding same as the mode of UL subslot group suitable With UL subslot.

Above-mentioned various modes, specific implementation example can be used in combination in the absence of conflict.

It is all UL subslot (including different length when base station is that UE configuration PUCCH resource collection is combined Subslot) a PUCCH resource collection is configured to be combined.Base station and UE agreement, correspond to the UL subslot of a specific length, If the terminating symbol of a PUCCH resource in the PUCCH resource collection is combined has exceeded the end of the UL subslot Symbol, UE or base station are handled in following manner: UE is undesirable to be instructed to, which transmits on the UL subslot； Or, base station forbids indicating that the PUCCH resource is transmitted on the UL subslot for UE；Or, if the PUCCH resource is indicated on When transmitting in the UL subslot, the symbol in the PUCCH resource beyond the UL subslot terminating symbol is truncated/is beaten Fall.

Base station is that UE one PUCCH resource collection of configuration is combined, and all UL subslot are (including different length Subslot it) is all combined using this PUCCH resource collection.For example, in UL slot UL subslot pattern " 4343 ", then right In a length be 3 symbol UL subslot, in the PUCCH resource collection of configuration is combined, it is possible to which there are PUCCH resources Terminating symbol has exceeded the terminating symbol of the UL subslot.Such as PUCCH resource is 4 symbols, primary sign index is 0, Symbolic number is 4, then the PUCCH resource terminating symbol has exceeded the UL for the UL subslot of 3 symbols Subslot terminating symbol then, can be by the way of following for the UL subslot:

UE is undesirable, and base station indicates that the corresponding PUCCH resource of the corresponding HARQ-ACK of a PDSCH is 4 symbols PUCCH resource, because PUCCH resource terminating symbol can exceed the terminating symbol of the UL subslot.

Alternatively, base station forbids indicating that UE transmit one in the UL subslot and surpasses for the UL subslot of 3 symbols Cross the PUCCH resource of the UL subslot terminating symbol.

Alternatively, base station and UE agreement, if base station indicates a PUCCH resource, and the PUCCH resource terminating symbol is super The terminating symbol of the UL subslot is gone out, then the symbol in PUCCH resource beyond the UL subslot terminating symbol is cut Break or be struck off, does not transmit, only use in the PUCCH resource without departing from the symbol transmission of the UL subslot terminating symbol.

It is simplest that this mode is that configuration PUCCH resource collection is combined, and signaling overheads is the smallest, and disadvantage is exactly to cooperate PUCCH resource is possible to not meet the length requirement of each UL subslot, so additional mechanism is needed to be handled or adjusted Degree limitation, and PUCCH resource negligible amounts actually available in each UL subslot are eventually led to, because some cannot be fine Use.

It is all UL subslot (including different length when base station is that UE configuration PUCCH resource collection is combined Subslot) a PUCCH resource collection is configured to be combined.Base station and UE agreement, correspond to the UL subslot of a specific length, Permit if the beginning notation index of a PUCCH resource in the PUCCH resource collection is combined has exceeded the UL subslot Perhaps beginning notation index, UE or base station are handled in following manner: UE is undesirable to be instructed to, and the PUCCH resource is in the UL It is transmitted on subslot；Alternatively, base station forbids indicating that the PUCCH resource is transmitted on the UL subslot for UE.

Base station is that UE one PUCCH resource collection of configuration is combined, and all UL subslot are (including different length Subslot it) is all combined using this PUCCH resource collection.For example, in UL slot UL subslot pattern " 4343 ", then right In a length be 4 symbol UL subslot, in the PUCCH resource collection of configuration is combined, it is possible to which there are PUCCH resources Start the beginning symbol that symbol has exceeded the permission of the UL subslot.Such as PUCCH resource is 1 symbol, primary sign rope 3 are cited as, symbolic number 1 is shown then the beginning notation index of permission is 0,1,2 for the UL subslot of 3 symbols So, it is 3 which, which starts notation index, has exceeded the beginning notation index of UL subslot permission, then, for this UL subslot, can be by the way of following:

UE is undesirable, and base station indicates that the corresponding PUCCH resource of the corresponding HARQ-ACK of a PDSCH is 4 symbols PUCCH resource, because PUCCH resource starts the beginning notation index that notation index can allow beyond the UL subslot.

Alternatively, base station forbids indicating that UE transmit one in the UL subslot and surpasses for the UL subslot of 3 symbols Cross the PUCCH resource of the beginning notation index of UL subslot permission.

It is simplest that this mode is that configuration PUCCH resource collection is combined, and signaling overheads is the smallest, and disadvantage is exactly to cooperate PUCCH resource is possible to not meet the requirement for the beginning notation index that each UL subslot allows, so needing additional machine System is handled or is dispatched limitation, and eventually leads to PUCCH resource negligible amounts actually available in each UL subslot, because It cannot be used well for some.

Embodiment 5

It is all UL subslot (including different length when base station is that UE configuration PUCCH resource collection is combined Subslot) a PUCCH resource collection is configured to be combined.Base station and UE agreement, correspond to the UL subslot of a specific length, Integrate from the PUCCH resource in being combined as UE instruction a PUCCH resource transmitted in the UL subslot when, the PUCCH Resource terminating symbol allows the terminating symbol beyond the UL subslot, but UE does not expect that the terminating symbol of the PUCCH resource is super The terminating symbol of UL slot where the UL subslot out.Base station side be it is same, base station is UE from the PUCCH resource Collection is combined middle finger and shows a PUCCH resource and when the PUCCH resource is transmitted in a UL subslot, the PUCCH being instructed to Resource terminating symbol allows the terminating symbol beyond the UL subslot, but the PUCCH resource terminating symbol does not allow beyond this The terminating symbol of UL slot where UL subslot.

Base station is that UE one PUCCH resource collection of configuration is combined, and all UL subslot are (including different length Subslot it) is all combined using this PUCCH resource collection.For example, in UL slot UL subslot pattern " 4343 ", then right In the 2nd, 4 length be 3 symbol UL subslot, in the PUCCH resource collection of configuration is combined, it is possible to which there are PUCCH moneys The terminating symbol in source has exceeded the terminating symbol of the UL subslot.Such as PUCCH resource is 4 symbols, primary sign index It is 0, symbolic number 4, then, when transmitting the PUCCH resource, can be used following for the 2nd, 4 UL subslot Mode:

For the 2nd UL subslot, the terminating symbol of the PUCCH resource can exceed the end of the UL subslot Symbol, but without departing from the terminating symbol of UL slot where the UL subslot, so, which can be indicated on this It is transmitted in UL subslot.

For the 4th UL subslot, the terminating symbol of the PUCCH resource can exceed the end of the UL subslot Symbol, but the terminating symbol of UL slot where also having exceeded the UL subslot, so, the PUCCH resource is in the UL Processing in subslot can be (and mode in embodiment 3):

UE is undesirable, and base station indicates that the PUCCH resource is transmitted in the UL subslot.

Alternatively, base station forbids indicating that the PUCCH is transmitted in the UL subslot.

Alternatively, base station and UE agreement, if base station indicates the PUCCH resource and transmits in the UL subslot, Symbol in the PUCCH resource beyond the UL slot terminating symbol is truncated or is struck off, and does not transmit, only uses this Without departing from the symbol transmission of the UL slot terminating symbol in PUCCH resource.

Embodiment 6

Configure a public PUCCH resource set for UE, the PUCCH resource in this PUCCH resource set allow across UL subslot in UL slot, the i.e. primary sign of PUCCH resource are somebody's turn to do in the UL slot in a UL subslot The terminating symbol of PUCCH resource is in another UL subslot in the UL slot.Different UE can share one it is public PUCCH resource set.

When specifically used, if base station is that UE configures public PUCCH resource set (public PUCCH resource set It is an optional configuration set), when base station is that UE indicates PUCCH resource, while should by specific signaling or instruction in secret PUCCH resource comes from public PUCCH resource set, or from dedicated PUCCH resource set (in the above embodiments 1~5 PUCCH resource may be considered the dedicated PUCCH resource set of UE).For example, the minimum control that base station and UE agreement pass through PDCCH Channel processed first (Control Channel Element, CCE) indexes to imply the HARQ-ACK of the PDSCH of PDCCH scheduling Corresponding PUCCH resource is from public PUCCH resource set or dedicated PUCCH resource set.Such as, arrange the minimum CCE index is even number, then base station is that the PUCCH resource of UE instruction corresponds to public PUCCH resource set, arranges the minimum CCE index is odd number, then base station is that the PUCCH resource of UE instruction corresponds to dedicated PUCCH resource set.Vice versa.If Base station is not that UE configures public PUCCH resource set, then it is assumed that no longer needs to indicate the PUCCH resource from public for UE Or dedicated PUCCH resource set.Specific signaling instruction above-mentioned refers to, in Downlink Control Information (Downlink Control Information, DCI) in introduce corresponding bit domain, to indicate the PUCCH resource from public PUCCH resource Set still comes from dedicated PUCCH resource set.

Here public PUCCH resource set can be currently based on UL slot configuration, i.e., public PUCCH resource The primary sign range that PUCCH resource in set allows is 0~13, lasting symbolic number 1,2,4,5,6,7,8,9,10,11, One in 12,13 and 14.Dedicated PUCCH resource can configure by the way of in previous embodiment 1~5.

One supplement example also supports to be that UE configures public PUCCH resource set, the public PUCCH resource here The primary sign and terminating symbol of PUCCH resource in set are that UE configuration is dedicated always in same UL subslot PUCCH resource in PUCCH resource set allows the UL subslot in across UL slot, i.e. the primary sign of PUCCH resource exists In the UL slot in a UL subslot, and another UL of the terminating symbol of the PUCCH resource in the UL slot In subslot.

In the case that the method for above-described embodiment 1- embodiment 6 is not conflicted with one another when implementing, it can be used in combination.
