Background technique

In the new radio (NR) mobile communication system, there are two types of support for PUCCH information transmission: short PUCCH and long PUCCH, respectively. The long PUCCH transmits a PUCCH message using a transmission symbol that transmits more PUCCH information than the short PUCCH. In general, the short PUCCH generally occupies one or two transmission symbols of the PUCCH for transmission, and the long PUCCH may occupy at least 4 transmission symbols of the PUCCH to complete the transmission of the PUCCH.

detailed description

The present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

As shown in FIG. 1 , this embodiment provides a resource scheduling method for a long PUCCH, which is applied to a base station, and includes:

Step S110: Configure an alternate length supported by each time slot according to the time slot parameter of the time slot; wherein the candidate length is an alternative value of the number of transmission symbols supported by the time slot for PUCCH information transmission. The time slot parameter includes: a time slot type;

Step S120: Select an alternate length supported by a target time slot as a target length, where the target time slot is a currently scheduled time slot for the PUCCH information transmission;

Step S130: Informing the user equipment UE of the target time slot and the target length, where the target length is used to indicate a transmission symbol used for the PUCCH transmission from the target time slot. Number.

The resource scheduling method for the long PUCCH provided in this embodiment is a method applied to a base station. In this embodiment, the base station may be a communication device for resource scheduling of a long PUCCH, such as an evolved base station (eNB) and a next generation base station (gNB).

In step S110, the alternative lengths supported by the various time slots are first configured. A time slot is a unit of transmission resources, and the time slot is generally divided into two types according to the number of transmission symbols it includes, one is a time slot including 7 transmission symbols, and the other is 14 transmissions. The time slot of the symbol. In this embodiment, the transmission symbol is also a unit of transmission resources, and the transmission resource corresponding to the transmission symbol is smaller than the transmission resource corresponding to the time slot. The transmission resources herein may correspond to time-frequency resources in communication. In the embodiment of the present invention, the candidate length is generally less than all the selections of the number of transmission symbols supported by the corresponding time slot for PUCCH information transmission. For example, one slot is used for the transmission length of the PUCCH information to be S1, and the number of the alternative lengths may be equal to or smaller than the S1, preferably smaller than the S1.

The time slot may be an uplink transmission time slot and an uplink and downlink mixed transmission time slot according to the transmitted information. The uplink transmission time slot here is only used for the transmission of uplink information. The uplink and downlink hybrid transmission time slots, part of the transmission symbols are used for uplink transmission, and some are used for downlink transmission.

The number of transmission symbols used for PUCCH information transmission supported by different time slots in this embodiment is different. For example, all time slots in the uplink transmission time slot can be used for transmission of PUCCH information of the user equipment, and only part of the transmission symbols in the uplink and downlink hybrid transmission time slots can be used for transmission of PUCCH information of the UE, and each time The number of slots used for PUCCH information transmission also depends on the number of transmission symbols that the slot itself includes. For example, a time slot including only 7 transmission symbols obviously provides up to 7 transmission symbols for transmission of PUCCH information of the UE, and it is impossible to exceed 7 transmission symbols.

In the present embodiment, an alternative length for PUCCH information transmission supported by various time slots is configured in advance. The alternate length of each time slot may be one or more.

After the setting of the candidate length supported by the various time slots is completed, when the UE performs long PUCCH scheduling, the candidate length is selected in combination with the configured alternative length, and one of the candidate lengths is selected as the target length, and is notified to UE. In this way, the UE can know how many transmission symbols are currently used for transmission of PUCCH information on the target time slot.

In this embodiment, the base station may notify related information of the target time slot and the target length by using Downlink Control Information (DCI) sent to the terminal. For example, the message such as the UCI carries the slot identifier or the resource identifier of the target slot. In some embodiments, the length indication of the target length may also be carried in the message such as the DCI.

In this embodiment, the configuration of the candidate length is used to limit the candidate length of the target length for the subsequent PUCCH resource scheduling, thereby reducing the scheduling complexity and reducing the complexity caused by the high complexity. Signaling overhead, which has the characteristics of low complexity and low signaling overhead.

Optionally, the step S110 may include:

And configuring, according to the time slot parameter, a length set for the time slot type, where the length set includes an alternate length supported by the corresponding time slot type;

The step S120 may include:

Selecting one of the candidate lengths from the set of lengths corresponding to the target time slot as the target length.

In this embodiment, for each time slot that can be used for PUCCH information transmission of the UE, a length set is configured, and the elements in the length set are candidates for the PUCCH information transmission supported by the corresponding time slot for the UE. length. In this case, after the target time slot is determined in step S120, an alternative length may be selected from the set of lengths corresponding to the target time slot as the target length.

In other embodiments, the step S110 may include:

Configuring a length set for each type of time slot, in combination with the coverage of the UE and/or the coverage requirement of the UE and the time slot parameter, where the length set includes: support for each type of time slot type The alternate length of PUCCH information transmission.

The step S120 may include:

And selecting one of the candidate lengths from the set of lengths of the target time slot configuration as the target length according to a current distribution status of the UE and/or a coverage requirement of the UE.

In the embodiment, the step S110 may be a distribution status of the UE, where the distribution status may include: the base station covers parameters such as a distribution density and a distribution position of the UE in the formed cell. The coverage requirement of the UE is the number of symbols that the UE needs to transmit to the base station by using the PUCCH to carry the PUCCH information.

The distribution positions of the UEs are different, and in order to ensure the reception effect of the base station, different target lengths may need to be configured. The coverage requirements of the UE are different, and different target lengths need to be configured as well. In this embodiment, at least one of the current distribution status of the UE and the coverage requirement of the UE is combined, and the UE using the time slot is specifically configured with a suitable length set for at least one transmission time slot. When the resource scheduling of the PUCCH is performed using the time slot of this type, an alternative length may be selected from the length set as the target length.

In this embodiment, since the configuration is based on the current distribution status of the UE and/or the coverage requirement of the UE, the configured alternative length is required to meet the current distribution coverage requirement, so the candidate length is reduced here. number.

In a specific implementation process, the step S110 may configure a length set for the UE according to the acquired distribution status of the UE and/or the coverage requirement of the UE and the time slot parameter according to the acquired UE's distribution status and the preset time interval of the unequal length.

The time slot parameters herein may include: the maximum number of transmission symbols that can be provided by different types of time slots, the number of transmission symbols that can be used for PUCCH information transmission of the UE, and the number of transmission symbols that can be used for PUCCH information in the time slot. Information such as the location of the distribution.

In this embodiment, a time set is configured for each time slot, and the length set includes an alternative length of one or more time slot types. And the candidate length in the set of lengths has a corresponding relationship with the corresponding slot type.

When the resource of the PUCCH is allocated to the UE in step S120, if the target time slot is determined, the candidate length corresponding to the target time slot may be searched in the length set, and the selected candidate length set is selected. One of the target lengths.

There are various implementations of the step S120. Several options are provided below:

Optional one:

When different UEs of the same type or different UEs with the same coverage requirement are distributed around the base station in a ring shape, one candidate is selected from the first type of length set of the target time slot configuration according to the coverage requirement of the UE. The length is taken as the transmission length.

Different UEs of the same type may have the same coverage requirements or the same communication capabilities, or the same communication quality requirements. Covering different UEs with the same requirements, may be different types of terminals, but with the same coverage requirements. These UEs are distributed in a ring around the base station. In this case, the candidate lengths in the length sets of these UEs may be more dispersed, and does not necessarily exhibit a certain rule. For example, when the time slot for transmission of PUCCH information is a time slot including 14 transmission symbols, the length set that can be configured for one of the UEs is {4, 7, 11, 14} and the like. In this embodiment, in order to simplify the configuration of the length combination, the same type of UEs or the UEs with the same coverage requirements, which are distributed around the base station, may be uniformly configured with the same length set, thereby simplifying the configuration of the length set and reducing the base station. The amount of data stored.

Option 2:

When the UE is distributed in the cell edge region, selecting one candidate length from the second type of length set of the target time slot configuration as the target length according to the coverage requirement of the UE;

When the UE is distributed in the central area of the cell, one of the candidate lengths is selected as the target length from the set of the third type of length configured by the target time slot according to the coverage requirement of the UE; wherein the third type The mean of the alternative lengths in the set of lengths is greater than the mean of the alternate lengths of the set of lengths of the second class.

In this embodiment, the cell formed by the coverage of the base station is divided into a cell edge area and a cell center area. In this embodiment, the cell center area is closer than the cell edge area to the base station.

Generally, the farther the UE is from the base station, in order to ensure the transmission quality, more transmission symbols may be required, and the transmission length is larger.

Therefore, in this embodiment, when the UE using the time slot is located in the cell edge area, the configured length set is a second type of length set, and when the cell is located in the cell center area, the configured length set is a third type of length set; The alternative lengths in the first type of length set and the second type of length set may be partially identical or completely different. But overall, the mean of the alternative lengths in the second set of lengths is less than the mean of the alternative lengths in the third set of lengths. In this case, it is ensured that the UE located in the cell edge area has a greater probability of transmitting PUCCH information using a larger target length.

In summary, in step S110 of the embodiment, three different types of length sets are configured according to information such as the distribution status and coverage requirements of the UE. The alternative lengths included in the first type of length set may be randomly generated, and the alternate lengths are more dispersed in one time slot. The alternative lengths included in the second type of alternative length are typically small. The alternative lengths included in the third type of length set are typically larger to meet the personality requirements of UEs with different distribution conditions and/or different coverage requirements to ensure the quality of PUCCH information transmission.

Optionally, the step S110 may include:

Configuring a length set for the UE according to the coverage capability of the UE and the time slot parameter; wherein the length set includes: an alternative length for the PUCCH information transmission supported by the UE by using the time slot type;

The length of the target slot supported by the target slot is selected as the destination transmission length, including:

An alternative length supported by the target time slot is selected from the set of lengths as the target length.

Here, the coverage capability of the UE may be a coverage distance for the UE to transmit information using a single transmission symbol. The time slot parameter can be referred to the foregoing embodiment, and will not be described here.

In this embodiment, the length set of the UE is separately configured according to the coverage capability and the slot parameter of the UE. The length set configured for the UE in this embodiment includes: the PUCCH information supported by the UE by using the slot type. The alternate length of the transmission. That is, the slot type that the UE can use and the candidate length corresponding to each slot type are configured in the set. In this embodiment, a length set is configured for each UE, and the length set includes an alternative length of one or more slot types. And the candidate length in the set of lengths has a corresponding relationship with the corresponding slot type.

By configuring the length set for each UE and then determining the target length by combining the length sets of the single UE, it is obvious that the complexity of the resource scheduling of the PUCCH is reduced, and the current distribution status and/or coverage requirements of the UE can also be combined. Thereby, the transmission success rate and/or reception quality of the subsequent PUCCH information and the like can be ensured.

In some embodiments, the unified configuration of the length set may be performed according to the UE having the same coverage capability, the number of configured length sets may be reduced, and the information retrieval of subsequent PUCCH resource scheduling may be simplified.

Optionally, in this embodiment, the length set configuration may be uniformly performed on all UEs located in the cell edge area and the cell center area, based on the distributed location of the UE, the coverage capability of the UE, and the coverage requirement. When a single UE is configured separately, the number of configured length sets can be reduced, the amount of data generated by the length set storage in the base station can be reduced, and the retrieval amount of the length set in step S120 can be reduced, thereby simplifying resource scheduling of the PUCCH again.

Optionally, in order to further reduce the signaling overhead of informing the UE of the target time slot and the target length, in some embodiments, the method further includes:

The target length of the PUCCH information transmitted by different UEs is unified.

After the unified target length is sent to the UE, after receiving the target length, the UE compares the target length with the required length that satisfies the coverage requirement. If the two are inconsistent, the power control is automatically performed.

In some embodiments, the method further includes:

Sending a power control indication to the UE, where the power control indication is used to trigger the UE to perform power control of PUCCH information transmission based on the target length and a required length that satisfies the coverage requirement. The method is performed by the base station instructing the UE to perform power control.

Regardless of which UE uses a uniform target length, the base station can transmit the relevant information of the target time slot and/or the target length to the UE adopting the same target length through broadcast signaling or multicast signaling, thereby reducing signaling overhead. .

When the target length is unified, the target length of each UE may be determined, and the target length with the largest number of UEs currently used may be selected as the target length of other UEs, so that a separate transmission that may reduce the power control indication may be ensured.

In some embodiments, the currently provided target length may not meet the coverage requirement of the UE due to the unified target length. For such a UE, the base station sends a power control indication to the UE, and the power control indication is used to make the UE adopt the target length. The allocated uplink transmit power transmits PUCCH information.

In this embodiment, the power control indication may also be multicast or broadcast together with the target length. If the UE performs power control after receiving the UE, the UE needs to determine whether the currently given target length meets the device coverage requirement. If it is not satisfied, it is adaptively adjusted for power control, and if it is satisfied, power adjustment is not performed.

The power control follows the following principles:

When the UE configures the long PUCCH to have a required length of L1, and the length of the target that is extended or shortened by power control is L2,

When L1 < L2, it is necessary to expand the number of transmission symbols, and at this time, each of the transmitted L2 transmission symbols has a smaller work emissivity than each of the original transmission symbols;

When L1>L2, the number of transmission symbols needs to be shortened, and each of the L2 transmission symbols in the shortened transmission symbol has a larger transmission power than each of the original transmission symbols;

When L1 = L2, power adjustment processing is not performed.

In summary, different power transmission symbol lengths are carried by power control to carry the same total energy, achieving the same coverage capability.

Optionally, the unit length of the PUCCH information that is unified by the different UEs includes:

The target length of the UE that will perform resource multiplexing of PUCCH information is unified.

In this embodiment, the target length is unified, and only the UEs that need to perform resource multiplexing of PUCCH information are unified in the target length. The transmission resources herein may include: time domain resources and frequency domain resources. The UEs that need to perform resource multiplexing perform unitization of the target length, so that the transmission lengths of the UEs for PUCCH information transmission are equal in length, which can simplify subsequent resource multiplexing and reduce the difficulty of resource multiplexing.

In some embodiments, if the target length of the UE that needs to perform resource multiplexing is unified, the method further includes:

Determining the target multiplexing mode of resource multiplexing, where the multiplexing mode may include: time division multiplexing, code division multiplexing, frequency division multiplexing, etc.; for example, time domain orthogonal cover code multiplexing, frequency domain orthogonal coverage Code multiplexing and simultaneous use of time domain orthogonal code multiplexing and frequency domain orthogonal code multiplexing.

The multiplexing parameter indicating the target multiplexing mode is sent to the UE. In this way, the UE receives the multiplexing parameter, and then sends a PUCCH transmission based on the multiplexing parameter, which naturally implements resource multiplexing.

As shown in FIG. 2, this embodiment provides a method for transmitting an uplink control channel (PUCCH), which is applied to a user equipment UE, and includes:

Step S210: Receive indication information indicating a target time slot and a target length sent by the base station, where the target length is one of pre-configured alternative lengths of the target time slot; the candidate length is the time slot support An alternative value for the number of transmission symbols used for PUCCH information transmission;

Step S220: Transmit PUCCH information using L' transmission symbols in the target slot according to the indication information, where L' is the target length.

The method provided in this embodiment is a method applied to a UE. First, in step S210, the UE receives indication information of the target time slot and the target length notified by the base station, for example, the aforementioned DCI, but is not limited to DCI. The indication information may directly carry the slot identifier of the target slot and the length indication of the target length. In other embodiments, the indication information may further carry other indication information, and other indication information and target The slot and/or the target length have a corresponding relationship, and after receiving the indication information, the UE has a corresponding relationship with the target time slot and/or the target length based on the other indication information, and determines the target time slot and the target length indicated by the current base station. . Therefore, in step S220, the target time slot for PUCCH information transmission may be determined according to the indication information, and the number of transmission symbols equal to the target length is selected on the corresponding target time slot to perform the PUCCH information transmission.

Optionally, the method further includes:

Receiving a power control indication sent by the base station; the power control indication herein may be an indication that the UE may need to perform uplink transmit power adjustment, and may be one or more bits, and may be an indication indicating the target time slot and/or the target length. The information may be sent separately, and may be broadcast information or multicast information, or may be separately sent to the unicast indication information of the UE that needs to be adjusted. If the power control indication is unicast indication information, it is preferably a determination indication indicating that power adjustment is performed.

The method further includes:

The uplink transmit power is determined according to the power control indication, the target length, and the required length that satisfies the coverage requirement.

In some embodiments, the UE does not receive the power control indication sent by the base station, and the method may include:

Comparing the target length and the required length, if the target length and the required length are inconsistent, automatically determining the uplink transmit power according to the target length and the required length.

In the embodiment of the present invention, determining the uplink transmit power according to the target length and the required length may include:

When the target length is consistent with the required length, the PUCCH information is sent by using the default uplink transmit power. If the target length is less than the required length, the uplink transmit power of the PUCCH information needs to be increased. If the target length is greater than the required length, the uplink transmit needs to be reduced. power. The magnitude of the power adjustment or the amount of each adjustment is positively correlated with the ratio of the target length to the required length.

In the embodiment of the present invention, the transmission length, the target length, and the candidate length may all be the number of transmission symbols to be described.

Optionally, the first receiving unit 210 is further configured to receive a power control indication sent by the base station.

The type of the UE is not limited in the embodiment of the present invention.

As shown in FIG. 5, this embodiment provides a resource scheduling method for a long uplink control channel (PUCCH), which is applied to a base station, and includes:

Step S310: splitting the target length corresponding to the resource of the long PUCCH of the UE into a symbol combination including one or more transmission symbols;

Step S320: Select a resource multiplexing manner based on the symbol combination according to the time-frequency resource corresponding to the symbol combination.

Step S330: Send a resource scheduling indication to the UE according to the resource multiplexing manner, where the resource scheduling indication is used to trigger the UE to perform multiplexing transmission of PUCCH information in the corresponding symbol combination.

Embodiments of the present invention provide another method for resource scheduling of a long PUCCH. In this embodiment, the number of transmission symbols (ie, the target length) used by the UE to transmit PUCCH information is first determined. Usually, the target length is not less than 1, and is generally an integer not less than 2. After determining the target length, a symbol combination of the target length is performed. For example, if the target length is 4, it can be split into a symbol combination of 2+2.

After the splitting of the symbol combination is completed, the corresponding time-frequency resources are combined according to the symbol, and resource multiplexing is performed with other UEs. For example, UE A has a target length of 4, which is the first, third, sixth, and seventh transmission symbols on slot 1, and UE B has a target length of 3, and is the second on slot 1. 6 and 7 transmission symbols. If the resource multiplexing of the entire PUCCH information of the UE A and the UE B is performed at this time, the target lengths of the two UEs cannot be performed, but in this embodiment, the target length of the UE A may be split. Split into two symbol combinations, the first and third transmission symbols are one symbol combination, the sixth and seventh transmission symbols are another symbol combination, and the target length of UE B is split, and the second transmission is performed. The symbol is treated as a symbol combination alone, and the 6th and 7th transmission symbols are regarded as one symbol combination. Then UE A and UE B can perform resource multiplexing of the 6th and 7th transmission symbols on the internship 1, using the code. Sub-multiplexing.

Therefore, in the embodiment, by splitting the target length and forming the symbol combination, resource multiplexing based on symbol combination can be facilitated between different UEs, and the resource reuse rate is high, and the resource utilization is high. At the same time, resource reuse is easily achieved by splitting the target length.

It should be noted that the resource scheduling method for the long PUCCH in this embodiment may be used in combination with the foregoing method for determining the target length based on the candidate length of the slot. That is, before the step S310, the target length is first determined according to the method shown in FIG. 1.

Optionally, the step S310 may include:

The target length is split into at least one basic length, wherein the basic length includes one or more transmission symbols.

In the embodiment, the basic length may be a preset length. In this embodiment, the basic length may be a minimum length of splitting, and may be a positive integer of 1, 2, etc., and is preferably a positive integer not less than 2. Of course, the basic length may be 1, and if the basic length is 1, the resource multiplexing of a single transmission symbol for PUCCH information transmission is implemented. When the basic length is an integer not less than 2, resource multiplexing of at least two transmission symbols is achieved.

In some embodiments, the transmission symbols in one symbol combination may be distributed in a time domain or a frequency domain, or may be discontinuously distributed. To further simplify multiplexing, it is preferably continuously distributed in the time domain or in the frequency domain. A plurality of continuously distributed transmission symbols are divided into one symbol combination.

Optionally, the step S320 may include at least one of the following:

Different basic lengths of the same UE are time division multiplexed;

The basic length of the same time-frequency domain resource used by different UEs is code division multiplexing;

The basic length of the same time domain resource used by different UEs is frequency domain multiplexed;

The basic length of the same frequency domain resource used by different UEs is time domain multiplexed.

The basic length using the same time-frequency domain resource adopts code division multiplexing including: code division multiplexing based on frequency domain cyclic shift, code division multiplexing based on subcarrier or based on physical resource block.

In this embodiment, by multiplexing the transmission resources, the idle fragmented resources of the transmission resources can be fully utilized, the effective utilization of the resources is improved, the waste of the transmission resources is reduced, and the communication capacity of the communication system is improved.

Optionally, the step S310 may include:

When the target length is a reconstructed length in a set of lengths, splitting the target length into a base length in the set of lengths, wherein the reconstructed length is a transmission length formed by a combination of the base lengths .

The alternate lengths in the set of lengths in this embodiment may be the base length and the reconstructed length. The reconstruction length here can be split into multiple base lengths.

For example, a set of lengths is {4, 7, 11, 14}, 11 and 14 of the set of lengths are reconstructed lengths, 4 and 7 are base lengths; 11 can be split into 4 and 7 sums; Split into two 7. In this embodiment, the base length is a transmission length that cannot be split into other alternative lengths in the corresponding length set, and the reconstructed length may be a transmission length in the length set that can be split into multiple other alternative lengths. In the present embodiment, the normal reconstruction length is an alternative length obtained by addition or multiplication of one or more base lengths.

In the embodiment, when the transmission symbol splitting of the target length is performed, the reconstructed length is split into the base length, so that the target lengths of all the UEs are split to the base length, and the split combination can be used for symbol combination multiplexing. The probability of this is greatly improved, and the reuse rate of transmission resources can be improved, and the effective utilization of transmission resources can be further improved.

Optionally, the step S320 may include at least one of the following:

Symbol combinations of the same transmission length are multiplexed using time domain orthogonal cover codes;

Symbol combinations of the same transmission length are multiplexed using frequency domain orthogonal cover codes;

The symbol combination of the same transmission length uses both time domain orthogonal code multiplexing and frequency domain orthogonal code multiplexing;

The symbol combination of different transmission lengths is time-division multiplexed with the first priority and frequency division multiplexed with the second priority, wherein the first priority is higher than the second priority.

The transmission length here refers to the number of transmitted symbols. The same transmission length means that the number of transmission symbols is equal, and different transmission lengths mean that the number of transmission symbols is not equal.

After the symbol combinations of different UEs are split, they may be equal or unequal.

If the number of transmission symbols corresponding to the symbol combination of the two UEs is equal, the corresponding multiplexing mode may be performed according to the corresponding time-frequency resources of the corresponding symbol combination. For example, after the target length corresponding to the two UEs is split and includes a symbol combination in which the transmission lengths are equal and the time-frequency resources used are equal, the time-domain orthogonal cover code may be used for the symbol combination, or Frequency domain orthogonal cover code multiplexing, or simultaneous use of time domain orthogonal code multiplexing and frequency domain orthogonal code multiplexing.

When two UEs have the same transmission length of one symbol combination and use the same time domain resource, frequency division multiplexing or orthogonal cover code may be used for multiplexing.

In some embodiments, the lengths of the symbol combinations of the two UEs are different, but the two UEs have partial symbol combinations, and the time-frequency resources used are partially multiplexed, and then the time division multiplexing is prioritized, if time division multiplexing cannot be performed. After the scheduling requirements are met, resource multiplexing is performed in combination with frequency division multiplexing.

For example, UE A is assigned a symbol combination of 3 transmission symbols, and UE B is assigned a symbol combination of 2 transmission symbols. In order to simplify resource multiplexing, priority is given to time-division multiplexing according to the available transmission symbols of the current time slot. , that is, the two symbol combinations are separated in the time domain. If the currently used time slot includes only 4 available transmission symbols in the time domain, then at least one transmission symbol must be used by both UEs in the time domain at the same time. In this case, resource multiplexing is required in combination with frequency division multiplexing. use.

In some embodiments, the method further includes:

When the resource mapping is performed, the resource mapping with the target length equal to the reconstructed length is first performed, and then the resource mapping with the target length equal to the base length is performed.

In the embodiment, when the resource mapping is performed, the priority target length is equal to the reconstruction length mapping, and the target length is equal to the base length mapped to the time-frequency resource. When the mapping of the target length equal to the reconstruction length is performed, the target length may be split into the base length and then the resource mapping may be performed, and then the mapping of the target length equal to the base length may be performed, and the target length equal to the reconstruction length may be performed. Code division multiplexing, time division multiplexing or frequency division multiplexing.

In this case, first, the mapping of the reconstructed length is performed by using the available time-frequency resources, and when the resource mapping of the basic length is performed, the mapped portion of the base length and the reconstructed length are first mapped based on the same time-frequency resource. Code division multiplexing, complete code division multiplexing and the basic length of mapping, then time division multiplexing, complete time division multiplexing and then frequency division multiplexing to occupy as little time-frequency resources as possible.

With the resource mapping method provided in this embodiment, when multiplexing is performed, the multiplexing priorities are: code division multiplexing, time division multiplexing, and frequency division multiplexing. Practice has proved that this resource mapping method can minimize the waste of resources.

For example, the target length of UE 1 is 11, and the target length of UE 2 is 4, where 4 and 7 are the base length and 11 is a reconstructed length. The current time slot may only provide 11 transmissions for PUCCH information. When the resource mapping is performed in this embodiment, the resource mapping of the UE with the target length of 11 is preferentially mapped, and the resource mapping with the target length of 4 is the reconstructed length. Divide into the base length including a completed resource map, and then perform resource mapping. For example, by splitting the 11 into 4 and 7, UE1 and UE2 can implement resource multiplexing of 4 transmission symbols in the case where only 11 transmission symbols are provided in the target time slot.

In some embodiments, the step S310 may include:

When the UEs performing resource multiplexing have different target lengths or the same target length but the time-frequency resource portions corresponding to the target lengths are different, split into symbol combinations including one or more transmission symbols.

If the UEs that need to perform resource multiplexing have different target lengths, or the target lengths are the same but the corresponding time-frequency resources in the target length are partially different and cannot be completely reused, then the target length splitting and splitting are required. The combination of symbols is followed by multiplexing of symbol combinations.

Therefore, in some embodiments, the method further includes: when the target length of the UE that performs resource multiplexing is the same and the time-frequency resources used are the same, the time-domain orthogonal cover code multiplexing and the frequency domain orthogonal cover code are selected. PUCCH information transmission using time domain orthogonal cover code multiplexing and frequency domain orthogonal cover code multiplexing. In this case, it is obviously not necessary to split the target length, so that resource multiplexing can be performed directly based on the entire target length.

Certainly, in some embodiments, even if the target length of the UE performing resource multiplexing is the same and the corresponding time-frequency resources are the same, some transmission symbols are located at the end of the time slot, and if the resource multiplexing is performed, the reception quality of the base station may be degraded. At this time, the symbol attribute may be transmitted according to the transmission symbol position of the transmission symbol, or the target length may be split, so that one part of the symbol combination uses one multiplexing mode, and the other symbol combination uses another multiplexing mode. To ensure the quality of the transmission.

It is worth noting that the target length here can be determined by the method shown in FIG. 1 and the resource scheduling method based on the long PUCCH shown in FIG. 1.

As shown in FIG. 6, the embodiment provides a resource scheduling method for a long uplink control channel (PUCCH), which is applied to a terminal, and includes:

Step S410: Receive a resource scheduling indication.

Step S420: Determine, according to the resource scheduling indication, a symbol combination split by a target length corresponding to the resource of the long PUCCH;

Step S430: When transmitting PUCCH information, according to the resource scheduling indication, performing resource multiplexing of the symbol combination by using a corresponding multiplexing manner.

This embodiment is a method in the application UE. If the base station performs the splitting of the target length, resource multiplexing needs to be performed based on the symbol combination. The UE receives the corresponding resource scheduling indication. The resource scheduling indication may be related to the resource scheduling that may be provided by the DCI or the like. After receiving the resource scheduling indication, the UE may know which time slot is used, and which transmission symbols transmit PUCCH information on the time slot. The resource scheduling indication in this embodiment may also be used to explicitly or implicitly split the symbol combination. For example, the scheduling resource indication explicitly indicates the split symbol combination, and may be description information directly carrying the symbol combination in the resource scheduling indication. The scheduling resource implies the split symbol combination, which may include: the resource scheduling combination does not directly carry the description information of the symbol combination, but the UE may determine the current base station based on the corresponding relationship by using the correspondence between the other information and the symbol combination. Split. For example, the slot type A supports a splitting method, and the split length is split into a base length. The UE knows the base length and the reconstructed length of the slot in advance, and the target length indicated in the resource scheduling indication is the reconstructed length. The UE may determine the symbol combination according to the splitting manner of the reconstructed length, and the manner of combining the indicator symbols is one of the combinations of the hint splits. Of course, the above is only an example, and the specific implementation is not limited to any of the above.

As shown in FIG. 11, this embodiment provides a resource scheduling method for a long uplink control channel (PUCCH), which is applied to a base station, and includes:

Step S610: determining a target length of the resource for which the UE performs PUCCH information transmission;

Configuring a transmission symbol of the PUCCH information transmission on a time slot;

Step S630: Informing the UE of the inter-slot scheduling.

This embodiment provides a resource scheduling method applied to a long PUCCH of a base station. In this embodiment, if it is determined that the target length of the UE is greater than the maximum transmission length supported by the predetermined time slot, cross-slot scheduling is performed. In this embodiment, the resource scheduling of the PUCCH is implemented by using the inter-slot scheduling, and the resource scheduling of the PUCCH is completed once, and the simplified scheduling of the long PUCCH is implemented.

In the embodiment, the inter-slot scheduling may be performed by allocating a target length to multiple time slots to implement one scheduling. After completing the inter-slot scheduling, the UE will be informed of the scheduling, so that the UE will complete the transmission of PUCCH information in different time slots.

Optionally, the step S630 may include:

Notifying the UE of the number of slots participating in the inter-slot scheduling, the resource locations of each of the slots, and the transmission length allocated for each of the slots.

In this embodiment, the base station informs the UE and other configuration information to the UE, such as the number of slots used in the time slot, the resource location of each time slot, and the transmission length, so that the UE can directly transmit according to the configuration information after receiving the UE. .

In this embodiment, the resource location may be a resource identifier of a time-frequency resource corresponding to the time slot.

Optionally, the step S630 may include:

And notifying the UE of the target length and length set, wherein the length set comprises: an alternative length of the number of transmission symbols used for PUCCH information transmission supported by the time slots participating in the time slot scheduling.

In this embodiment, only the target length and the length set are notified to the UE. After receiving the length set and the target length, the UE may perform the inter-slot scheduling according to the negotiation with the base station in advance, or the default, or the current informed participation. The number of time slots, self-derived the number of transmission symbols currently provided by each time slot that participates in scheduling across time slots, and the location of the transmitted symbols.

In some embodiments, the step S620 can include:

Using the formula L=N*P; wherein the L is greater than or equal to L'; wherein, L' is the number of transmission symbols included in the target length; and the N is a slot participating in inter-slot scheduling The number of transmission symbols is the number of transmission symbols configured on each time slot.

When performing cross-slot scheduling in step S620 in this embodiment, cross-slot scheduling is performed using the formula L=N*P. If once N is determined and L' is determined, the value of P is relatively determined. In some embodiments, if L' and P are determined, then N is also determined. In the present embodiment, the PUCCH information transmission is performed by using a transmission length of equal length on different time slots. The N and the P may be configured by the base station according to requirements.

After completing the inter-slot scheduling, the base station may notify the UE of the scheduling result of the inter-slot scheduling, for example, notifying the UE of the slot identifiers of the N slots and L′, and then receiving the UE. After that, the P is naturally derived according to the above formula. Of course, the base station may also notify the UE of the slot identifiers of the N slots and the L′ and the P. Certainly, in some embodiments, the base station may further notify the UE of the length sets of L′ and P and each time slot, and the UE receives the foregoing parameters, and automatically derives which N times slots are selected by the current terminal to participate in the inter-slot scheduling. .

In summary, there are various ways for the base station to inform the terminal of the scheduling parameters for scheduling across time slots, and are not limited to any of the above.

Optionally, the step S620 may include:

Adopt formula

Wherein L is greater than or equal to L'; wherein, L' is a number of transmission symbols included in the target length; and N is a number of slots participating in inter-slot scheduling; the x _n The maximum number of transmission symbols used for PUCCH information transmission supported by the nth slot participating in the inter-slot scheduling.

In the present embodiment, the above

Determining the provided transmission length of each time slot participating in the inter-slot scheduling is simple to implement. When performing cross-slot scheduling in this manner, the base station may only inform the UE of the target length and the time slots that are scheduled to be scheduled across the time slots, and the UE may determine each one according to the length set corresponding to each time slot that is known in advance. The length of the transmission provided by the time slot, and so on. Of course, in some embodiments, the base station may of course inform all the information to the UE, and the UE may directly transmit the PUCCH information according to the scheduling result.

In some embodiments, the step S620 can include:

Adopt formula

Wherein, the L is equal to L′; wherein, the L′ is the number of transmission symbols included in the target length; the N is the number of slots participating in the inter-slot scheduling; the x _n is: The maximum number of transmission symbols used for the PUCCH information transmission supported by the nth slot participating in the slot scheduling, or the average number of transmission symbols participating in the provision of the pre-N-1 slot scheduled across the slot; x(N) is the number of transmission symbols used for the PUCCH information transmission by the Nth slot participating in the time slot scheduling.

In the embodiment, the number of transmission symbols used for the PUCCH information in the last time slot is determined by the number of transmission symbols provided by the target length and the first N-1 time slots. There is a waste of transmission symbols, which again increases the effective use of resources.

In one embodiment, the number of transmission symbols provided by the first N-1 time slot may be unequal, respectively, which is the maximum number of transmission symbols available for PUCCH information transmission that the corresponding time slot can provide. In another embodiment, the number of transmission symbols constituting the target length provided by the first N-1 time slot is equal.

In this embodiment, the method further includes:

Selecting a slot type supporting the target length for PUCCH information transmission of the UE;

The step S610 can include:

Inter-slot scheduling is performed when a slot type that supports the target length is not selected.

In this embodiment, the scheduling of the slot type is firstly avoided, and cross-slot scheduling is avoided as much as possible. If there is no slot type that can separately provide the number of transmission symbols required for the target length, then cross-slot scheduling is performed. .

It is worth noting that the target length here can be determined by the method shown in FIG. 1 and the resource scheduling method based on the long PUCCH shown in FIG. 1. After the cross-slot scheduling provided by this example, resource multiplexing may be performed as shown in FIG. 5 and the resource scheduling method based on the long PUCCH shown in FIG. 5.

Several specific examples are provided based on any of the above embodiments,

Example 1:

This example performs target length scheduling of PUCCH resources based on length set configuration in one slot.

The alternative length that the long PUCCH of the scheduled UE within a time slot can provide should be related to the time slot type. Two ways are provided to achieve target length selection of long PUCCHs of UEs in a slot.

Both of these approaches are based on a set of lengths, and the elements within the set of lengths (ie, the alternate lengths) are related to the type of slot.

There are two specific ways:

Method 1:

Length set configuration based on time slots. Each slot type corresponds to a plurality of length sets, and the same slot type can be configured with different length sets at different times. The scheduled UE within the slot selects an appropriate value from the set of lengths of the current slot configuration to satisfy the coverage requirement.

The division of the length set may take into account differences in coverage capabilities of multiple User Equipments (UEs).

Classification method 1, classified according to the coverage requirements of UEs. The UEs are mainly distributed on the endless band in a certain time slot. If the different padding patterns shown in FIG. 14 correspond to three different coverage areas, then {4, 7, 11, 14} or {4, 8, 12} and other relatively alternative lengths to meet the UEs several categories of coverage requirements. When UEs are almost evenly distributed in a cell, {4, 6, 8, 10, 12, 14} can be configured to cover all UEs. The UEs may be configured to be {4, 5, 6, 7} or {10, 11, 12, 13, 14} when they are mainly distributed inside the cell or at the edge of the cell.

Classification 2, based on the UEs coverage requirement classification, divides the subset of the already classified length sets according to the slot type. For example, {4, 6, 8, 10, 12, 14} is divided according to the slot type as follows, and the slot allocation length set {4} of 7 transmission symbols. 7 sets of lengths of uplink time slot allocations of transmission symbols {4, 6} and their subsets, set of time slot allocation lengths of 14 transmission symbols {4, 6, 8, 10} and their subsets, uplink transmission of 14 transmission symbols The time slot assigns a set of lengths {4, 6, 8, 10, 12, 14} and its subset.

For example, as shown in FIG. 15, the nth time slot and the n+2 time slot are of the same type, and the respectively configured length set n and length set n+2 may be the same or different. The type of the n+1th slot is different from the nth and n+2 slots, and the configured length set n+1 may be the same as or different from the length set n and the length set n+1. 15 is a schematic diagram of transmission symbols of the nth, n+1, and n+2 slots occupied by UE1, UE2, UE3, UE4, and UE5.

Method 2:

Based on the UE's length set configuration. Each UE is configured with a set of lengths that are associated with alternate lengths and slot types. One slot type will correspond to one or several values in the set of lengths configured to the UE. Different length sets may be configured when the same UE is scheduled in time slots (slot types may be the same or different) at different times. In one slot, the scheduled UE selects an appropriate value in the respective configured length set according to the type of the slot to satisfy the coverage requirement.

For example, as shown in FIG. 16, each UE is configured with a set of lengths. The nth time slot and the n+1th time slot have the same time slot type, wherein the same UE1 is scheduled, and the length set 1 and the length set 6 configured by the UE1 may be the same or different.

The target time slot corresponding to the resource of the long PUCCH of the UE1 in FIG. 16 includes a time slot n and a time slot n+2, and the length set corresponding to the UE1 includes: a length set of 1, which may be split into a specific implementation. Two length subsets, one length subset including an alternate length of one slot. The target time slot occupied by UE2 is time slot n, and the corresponding length set is length set 2. The target time slot occupied by UE3 is slot n+1, and the corresponding length set is length set 3. The target time slot occupied by UE4 is time slot n+1, and the corresponding length set is length set 4. The target time slot occupied by the UE 5 is the time slot n+1, and the corresponding length set is the length set 5. It is obvious that a set of lengths of one UE configuration may include one or more, and corresponding target time slots may include one or more.

Example 2:

This example provides scheduling of a target length of a power control based PUCCH within a time slot.

Different UEs allocate different target lengths of different long PUCCHs according to the coverage requirements. The power control can extend or shorten the allocated long PUCCH lengths during transmission implementation, so that the target lengths of different coverage requirements can be unified, and then unified. Resource reuse. Through this implementation, the variable length range supporting the long PUCCH in one slot can be reduced, which is advantageous for resource allocation scheduling and simplified multiplexing mode.

In one time slot, the transmission length of different long PUCCHs of the UEs may be extended or shortened by power control to a set of several values or a value M. Different time slot types and time slots of the same type at different times can be configured with different sets and M. Here M can be the target production after the unity.

For example, different lengths through power control realize that the variable length in one slot fills the number of uplink transmission symbols (when the time division multiplexing (TDM) of the side PUCCH is subtracted from the transmission symbol occupied by the short PUCCH), that is, The length of the PUCCH corresponding to all UEs coverage requirements in one slot is different. However, the target length of the PUCCH is the same when the actual transmission is implemented. Different time slot types have different numbers of uplink transmission symbols, which correspond to different candidate lengths of different PUCCHs. Specifically, it is assumed that the target length of the UE configuring the long PUCCH is P, and the target length that expands or shortens the length by power control is Q, and when P<Q, the number of extended symbols is required, and each of the expanded Q symbols is used. Compared with the original symbol, the transmission power of the symbol becomes smaller. When P>Q, the number of symbols needs to be shortened. At this time, each of the shortened Q symbols becomes larger than the original transmission power of each symbol. When P=Q, no processing is performed. In summary, power control enables different symbol lengths to carry the same total energy, achieving the same coverage capability; and achieving consistent target lengths of long PUCCHs in time slots, thereby reducing multiplexing complexity.

For example, as shown in FIG. 17, the nth and n+2th slots have the same type, and different PUCCH lengths may be allocated according to coverage requirements when scheduling the same UE, but different PUCCHs will be controlled by power control when the transmission is implemented. The length is extended to all upstream transmission symbols.

In FIG. 17, the target time slot corresponding to the resource of the long PUCCH of UE1 is time slot n or time slot n+2, and when the target time slot is time slot n, the four transmission symbols of the target length time slot n are occupied; When the target time slot is time slot n+2, the occupied target length is 6 transmission symbols of time slot n+2. The set of lengths corresponding to the UE1 includes: a set of lengths 1 and a set of lengths 6, wherein the set of lengths 1 is a combination of candidate lengths of the target slots and the length of the slots is n; Select a collection of lengths.

The target time slot occupied by UE2 is slot n, the corresponding length set is length set 2, and the occupied target length includes 5 transmission symbols of slot n.

The target time slot occupied by UE3 is slot n+1, the corresponding length set is length set 3, and the occupied target length includes 9 transmission symbols of slot n+1.

The target time slot occupied by the UE4 is the time slot n+1, and the corresponding length set is the length set 4, and the occupied target length includes 11 transmission symbols of the time slot n+1.

The target time slot occupied by the UE 5 is the time slot n+1, and the corresponding length set is the length set 5, and the occupied target length includes 7 transmission symbols of the time slot n+2. It is obvious that a set of lengths of one UE configuration may include one or more, and corresponding target time slots may include one or more. When a time slot is insufficient in the time domain to provide transmission symbols occupied by multiple UEs, the occupation of transmission symbols in different frequency domains may be provided, or code division multiplexing in the same time-frequency resource may be implemented.

Example 3:

For each element in the time slot, for each element of the length set, an independent resource block is configured for each candidate length, and resources are dynamically allocated according to the distribution of the candidate lengths of all scheduled UEs in the time slot, and the UE is informed, different resource blocks. There may be frequency division multiplexing (FDM) or time division multiplexing (TDM), and the resource blocks may be TDM, FDM, or CDM. The long PUCCH resource of the scheduling UE in the resource block corresponding to each candidate length may be informed to the UE in a relative position, that is, the UE may combine the location of the resource block to obtain the absolute resource location of the long PUCCH allocated in the resource block. , saving signaling overhead. Unoccupied resources within a resource block may be used for PUCSH data transmission or scheduling UEs of other PUCCH lengths. When scheduling UEs of other lengths, TDM or FDM is used with the current PUCCH length, and code division multiplexing (CDM) may also be used between the same candidate lengths. The following two CDM methods are available:

Option 1, frequency domain orthogonal code division multiplexing (for example, CDM in frequency domain cyclic shift, orthogonal code division multiplexing between frequency domain subcarriers, that is, orthogonal cover code (OCC) in frequency domain);

Option 2, time domain orthogonal code division multiplexing (such as time domain OCC), the two options can be used alone or in combination to increase multiplexing.

FIG. 18 is a schematic diagram of resource scheduling of a long UCCH of a UE, where the target length of UE1 is 14 transmission symbols, and the target length of UE2 is 10 transmission symbols.

In the embodiment of the present invention, the horizontal axis of FIGS. 15 to 23 can represent the frequency domain, and the vertical axis can represent the frequency domain.

Example 4:

Each slot is scheduled according to the target length of the UE, and UEs of different target lengths are mutually multiplexed, and there is no independent resource block allocated for the target length. TDM, FDM, and CDM can be used between PUCCHs of different target lengths. There is nothing special about FDM or TDM between different durations, but it is different from the CDM multiplexing method used for the same target length in LTE. Here, reasonable design is needed. CDM still contains two ways to reuse:

Option 1, frequency domain orthogonal code division multiplexing (for example, frequency domain cyclic shift CDM, frequency domain subcarrier orthogonal code division multiplexing, ie frequency domain OCC);

Option 2, time domain orthogonal code division multiplexing (such as OCC in the time domain), the two options can be used alone or in combination to increase multiplexing.

FIG. 19 is a schematic diagram of the same resource block being shared by UE1, UE2, and UE3; and the padding strips in FIG. 19 are target lengths corresponding to UE1, UE2, and UE3, respectively, corresponding to UE1, UE2, and UE3. The target length is different.

Example 5:

This example provides resource multiplexing of PUCCHs of different target lengths, and the specific multiplexing manner may be as follows: frequency division multiplexing in the frequency domain.

Mode 1, the resource of the long PUCCH includes several transmission symbols, which can be split into several symbol combinations and multiplexed in units of symbol combinations, for example, a CDM method based on cyclic shift.

Mode 2: The long PUCCH may also be extended in the frequency domain, including several subcarriers or a plurality of physical resource blocks (Physical, Resource Blocks, PRBs), or frequency domain code division multiplexing in units of subcarriers or PRBs, for example, based on frequency. Domain OCC. This method of multiplexing in the frequency domain can flexibly schedule resources and reduce resource fragmentation.

The above several symbol combination sizes (time domain and frequency domain resource size) may be the same or different. A PUCCH length split symbol combination resource allocation may be continuous or discontinuous in the time-frequency domain.

UEs of different lengths of PUCCH in one slot conform to the combined multiplexing mode. When a long PUCCH is generated by repetition based on the basic length, the basic length can be used as a symbol combination size standard to split the target length of the long PUCCH. Figure 20 shows a split view of a target length that can be split into a number of basic lengths.

Each transmission length will be split into several basic lengths, TDM between the basic lengths of the same UE, and the basic length of different UEs may be CDM, TDM or FDM. FIG. 21 is a schematic diagram of three UE multiplexing and four UE multiplexing based on Fouha combination.

Code division multiplexing includes: cyclic shift (shown in Figure 21) and frequency domain OCC (shown in Figure 22). The same UE in Figure 20 may employ the same or different cyclic shifts in different basic lengths. The basic lengths in Figure 22 and Figure 23 may be continuous or discontinuous on the time-frequency domain resources. Figure 23 provides a schematic diagram of two UE multiplexing and 4GE UEs, respectively.

All the basic lengths of the target lengths of the long PUCCHs constituting E need to indicate their resources separately. In order to reduce the signaling overhead caused by each basic length indicating the target length of the long PUCCH, it may be configured in several frequency domains or times. The basic length of the domain continuous distribution is multiplexed in units. Although scheduling flexibility is degraded, signaling can be greatly reduced. This method is applicable to the case where there are many sets of lengths and no nesting features between the slots, and the signaling overhead caused by complex multiplexing is avoided.

Example 6:

In Example 5, when the long PUCCH is split into a plurality of symbol combinations, time domain OCC multiplexing can be performed in a combination having the same number of transmission symbols, and the symbol combination at this time needs to satisfy certain conditions, for example, including several A transmission symbol of a demodulation reference signal (DMRS) and a number of uplink control information (UCI) transmission symbols. In addition, time domain OCC multiplexing can also be performed between combinations of the same size (time-frequency domain resources).

Although the above method can be used between long PUCCHs of any length, it does not maximize the multiplexing capability. Therefore, it is considered that if the multiplexing mode is supported, a number of alternative lengths supported within the time slot use a nested structure. The reuse rule adopts the target length from large to small resource mapping, nested multiplexing takes precedence, TDM takes the second place, and finally selects FDM.

Let the above several alternative lengths form a set {n1, n2, n3, ..., nx}, and the elements are arranged from small to large. Nested structure refers to the fact that several elements in the set are of basic length, and other lengths can be reconstructed by the basic length. For example, the value of 4 or 7 in {4, 7, 11, 14} is the basic length, and the alternative length of 11 or 14 is the reconstructed length. Nested multiplexing refers to splitting the reconstructed length into basic length parts and multiplexing them with the basic length. In this case, the basic length of multiplexing is the same, and the time domain OCC can be multiplexed, as shown in FIG. In Fig. 23, multiplexing of time-frequency resources is performed using transmission symbols located in the same resource block or one slot.

Specific steps:

According to the target length, resource mapping is performed from large to small, the same target length is time domain OCC multiplexing, and different targets or lengths are used by TDM first and FDM second.

When the basic length resource is mapped, the priority and the reconstructed length are nested and multiplexed, the TDM priority is second, and finally the FDM.

As shown in FIG. 23, a long PUCCH of length 14 and 11 is first mapped. When resource mapping, the reconstructed length of 14 transmission symbols is mapped and multiplexed with a basic length of 7 transmission symbols +7 transmission symbols, and 11 transmission symbols are used. The reconstructed length is mapped and multiplexed with a base length of 7 transmission symbols + 4 transmission symbols. Then, the mapping basic length, 7 transmission symbol priority and two 7 transmission symbols in 14 transmission symbols are multiplexed, and then 7 transmission symbols are multiplexed with 11 transmission symbols, 4 transmission symbol priority and 4 transmission symbols in 11 transmission symbols. Multiplexing, and multiplexing with 4 transmission symbols in 7 transmission symbols.

In a time slot, resource multiplexing between long PUCCHs of different target lengths may be selected using one or more of the examples 5 or 6. Different types of time slots and the same time slot type at different times can select different multiplexing modes. The multiplexing mode can be signaled to the UE by signaling or implicitly indicated by the slot type.

Example 7:

This example provides cross-slot scheduling in conjunction with multiple time slots.

In the multi-slot transmission mechanism, the target length of a long PUCCH of one UE is split into a plurality of slots for transmission. The inter-slot transmission is triggered when the target length of a long PUCCH configured by a UE scheduled in one slot is greater than the maximum value supported by the slot. The starting point for the design of the cross-slot transmission mechanism is that cross-slot transmission cannot affect normal single-slot transmission. That is to say, cross-slot is a high-level concept, and from a separate slot perspective, it is not known whether there is cross-slot transmission.

A long PUCCH priority scheduling that is transmitted across time slots in one slot, minimizing the transmission delay of one UE across slots.

In the multi-slot transmission mechanism, if the UE can know the slot type of the current slot and the subsequent slots in advance, and the slot type is closely related to the long PUCCH length set that can be transmitted, the UE can combine multiple slots to perform long PUCCH. Scheduling, reducing the possibility of transmission across time slots, saving signaling overhead. For example, when the long PUCCH lengths respectively transmitted by the nth time slot and the n+1th time slot are {4, 7} and {4, 7, 11, 14}, the UE of 11 or 14 can be placed. The n+1th time slot is scheduled, thus avoiding the situation of trans-slot transmission and reducing the additional signaling overhead.

Example 8:

In this example, in the multi-slot transmission mechanism, the number of slots N aggregated by the UE, the resource location of each slot, and the candidate length allocated for each slot are signaled to the UE. In this way, the alternate length allocated in each time slot is configurable and therefore more flexible. At this time, the determination of N needs to be jointly determined in combination with the coverage requirement and the occupation length allocated to each time slot. The resource location can be configured by the upper layer, but at the same time, the length set of different time slot configurations needs to be considered, and the occupied length allocated to a certain time slot should fall within the length set of the time slot configuration. In this mode, the total target length of the UE PUCCH is consistent between the configuration and the actual transmission length.

The length set in the following examples 9, 10, 11, and 12 refers to a set of all long PUCCH lengths supported in one slot determined in the manner of Example 1 or 2.

Example 9:

Under the multi-slot transmission mechanism, the long PUCCH cross-slot transmission target length and the length set of each slot configuration for aggregation are signaled to the UE. The number N of aggregated time slots and the resource location are derived from the total target length and the set of lengths of the time slot configuration. This means that the aggregated time slots will be contiguous by default unless the length set of a time slot does not contain the corresponding candidate length. In this case, the time slot is skipped and the same operation is performed in the next time slot.

Example 10:

This example provides a cross-slot scheduling method that occupies the same number of symbols in multiple time slots.

The target lengths of the UEs are transmitted evenly over N time slots with the same length when transmitting across time slots. Here the same length of the unit can be configured. Let the target length of the total long PUCCH of the UE be L', and the length of the uniform distribution in each slot is P, and the number of slots is N=(L/P). In practice, the total length of the transmission becomes L= P*N>=L'. This means that the actual length of the actual transmission may be greater than the configured target length.

As shown in FIG. 24, the target length of the long PUCCH of the UE is 19 symbols, and is evenly allocated in 3 slots with a length unit of 7 symbols. The actual transmission length is 21 symbols, which is greater than the configured target length of 19 symbols. .

Example 11:

The long PUCCHs of the UE are distributed in N aggregated time slots with different lengths when transmitting across time slots. The length allocation within N time slots is determined by the respective supported length sets. The aggregated N time slots adopt the maximum value of the supported PUCCH lengths. In this mode, the number of aggregated slots N will change according to the maximum length of the PUCCH supported by the aggregation slot. The specific method is: the first time slot of the aggregation adopts the maximum value n1 in the set length of the configuration, and the next time slot selects the minimum set of n1+n2>=L (total long PUCCH length) in the configured length set. If the value is not satisfied, the maximum candidate length is selected, and the same operation is continued in the next time slot until the condition is satisfied. In this mode, the number N of aggregated slots will change with the set of lengths supported by the aggregated slots, and implicit derivation is obtained. In addition, in this mode, there is also a case where the actual length of the actual transmission is larger than the configured target length. This mode maximizes the continuity between aggregated time slots.

As shown in FIG. 25, the target length of the long PUCCH of the UE is 16 symbols. When transmitting across the time slot, the first time slot occupies 7 symbols, and the second time slot occupies 14 symbols. The actual transmission length is 21 symbols, which is greater than the configuration length of 16 symbols.

Example 12:

In Example 10 and Example 11, the long PUCCH length is configured only considering the coverage requirement of the UE, which will cause the actual length of the actual transmission in Examples 10 and 11 to be larger than the target length of the prior configuration. That is to say, the total long PUCCH length of the UE is configured first, and then the length allocation is performed according to the length set supported by the aggregated time slot. It can be considered that when configuring the target length of the UE's total long PUCCH, not only the coverage requirements of the UE but also the slot aggregation modes in Examples 10 and 11 can be considered.

In Example 10, the long PUCCH length should be configured to allocate an integral multiple of the same length in each slot under the condition that the coverage requirement is satisfied. In Example 11, the length of the long PUCCH should be configured to be n(1)+n(2)+...+n(k) length, where n(1), n(2),...,n() K-1) indicates the maximum candidate length value in the first k-1 time slot support length sets of the aggregation, or the first k-1 time slots provide equal number of transmission symbols, and n(k) represents the kth aggregation. A slot supports an element in a set of lengths.

In summary, in Examples 10 and 11, the same rules are used for the lengths allocated in all time slots of the time slot transmission aggregation, which would result in the actual transmission lengths in Examples 10 and 11 being greater than the prior configuration. When the actual transmission length is greater than the configuration length, consider the allocation length determined using the rules in Example 10 and Example 11 for the first K-1 aggregation slots, but the last slot selection satisfies the transmission length provided by the long PUCCH as the last one. The minimum alternate length value in the set of lengths of the time slots. The length of the long PUCCH shall be configured to be n(1)+n(2)+...+n(k) length, where n(1), n(2), ..., n(k-1) Representing the length of allocation in the first K-1 time slots determined according to Embodiment 10 or Embodiment 11, and n(k) represents an alternative length in the k-th aggregation time slot support length set, the candidate length is The minimum candidate length that satisfies the UE's long PUCCH length.
