As shown in fig. 2, an embodiment of the present disclosure provides a resource allocation method, including:

Step S110: configuring a same Physical Uplink Control CHannel (PUCCH) resource set for a sub-slot included in one slot, wherein the PUCCH resource set includes: one or more PUCCH resources;

Here, each slot may be divided into a plurality of equal or unequal sub-slots. For example, in order to perform uplink feedback on a Physical Downlink Shared Channel (PDSCH) transmitted in a Downlink as quickly as possible, one uplink slot (slot) is divided into a plurality of equal uplink sub-slots (subslots). Thus, each uplink sub-slot may have a Hybrid Automatic Repeat request acknowledgement (HARQ-ACK) feedback opportunity. Compared with the implementation mode that only one HARQ-ACK feedback opportunity exists in one uplink time slot, the implementation mode can perform HARQ-ACK feedback in advance, and therefore the feedback time delay of the HARQ-ACK is obviously reduced.

Here, the PUCCH resource (PUCCH resource) may be a set of configuration parameters configuring the PUCCH resource. Here, the time domain symbols occupied by different PUCCH resources may be different, which makes the time domain symbols corresponding to the PUCCH resources more diverse, and the terminal UE can flexibly select the PUCCH resources of different time domain symbols, for example, transmit the HARQ-ACK message based on the PUCCH resources of different time domain symbols. Here, the base station may transmit configuration information in which the same PUCCH resource set is set for a sub-slot included in one slot to the terminal through RRC signaling in the RRC layer.

here, the same PUCCH resource set of the physical uplink control channel is configured for the sub-slots included in one slot, and it is not necessary to configure a respective PUCCH resource set for each sub-slot, so that when the configuration information of the PUCCH resource set is issued, it is not necessary to issue the configuration information of the PUCCH resource set for each sub-slot, thereby reducing overhead of issuing the configuration information.

Step S120: and when the time domain symbol occupied by the first PUCCH resource in the PUCCH resource set exceeds the boundary of the time slot, the first PUCCH resource is discarded.

The starting position and the ending position corresponding to the time domain symbol occupied by each PUCCH resource are required to be included in one slot. In one embodiment, a plurality of sub-slots included in one slot respectively and independently configure PUCCH resource sets, that is, each sub-slot in one slot is configured with a set of PUCCH resource sets matched with the time domain symbol length of the slot, which can ensure the flexibility of PUCCH resource configuration. However, configuring PUCCH resource sets independently for each sub-slot requires issuing many configuration information, which increases overhead of issuing the configuration information.

In another embodiment, only one set of PUCCH resource sets is configured for a sub-slot, and the set of PUCCH resource sets is applied to each sub-slot. However, in order to ensure that the time domain symbols occupied by the PUCCH resources in the set of PUCCH resource sets do not exceed the slot boundaries, the time domain symbols occupied by all PUCCH resources in the set of PUCCH resource set configurations must be contained within one sub-slot and cannot exceed the sub-slot boundaries. For example, in a sub-slot division mode in which each sub-slot occupies 2 time domain symbols, the time domain symbols occupied by the configured PUCCH resources are configured to be 2 at most, and since the time domain symbols occupied by the configured PUCCH resources are limited, this mode may limit the flexibility of PUCCH resource configuration, which may directly result in that the UE may not flexibly select PUCCH resources with more time domain symbols. For example, the UE cannot transmit the HARQ-ACK message through the PUCCH resource with a large number of time domain symbols. In the embodiment of the present disclosure, when a time domain symbol occupied by a first PUCCH resource in a PUCCH resource set exceeds a slot boundary, the entire first PUCCH resource is discarded, so that PUCCH resources occupying more time domain symbols can be configured, and an influence of coverage limitation of PUCCH channels occupying less time domain symbols, which is caused by that a UE can only use PUCCH occupying less time domain symbols when uplink power is limited or uplink quality is poor, is reduced. Here, discarding the entire PUCCH resource or discarding a part of the PUCCH resource means that data or information is no longer transmitted using all or a part of the physical resources mapped by the PUCCH resource configuration.

In the embodiment of the application, on one hand, the same physical uplink control channel PUCCH resource sets are configured for sub-slots included in one slot, so that it is not necessary to configure a respective PUCCH resource set for each sub-slot, and thus when configuration information of the PUCCH resource set is issued, it is not necessary to issue configuration information of the PUCCH resource set for each sub-slot, thereby reducing overhead of issuing the configuration information. On the other hand, when the time domain symbol occupied by the first PUCCH resource in the PUCCH resource set exceeds the slot boundary, the first PUCCH resource is discarded, so that PUCCH resources occupying more time domain symbols can be configured, and the influence of limited coverage of PUCCH channels occupying less time domain symbols, which is caused by that the UE can only use PUCCH occupying less time domain symbols when uplink power is limited or uplink quality is poor, is reduced. According to the embodiment of the application, the uplink coverage of the PUCCH can be improved, and the flexibility of the PUCCH resource in time domain configuration is improved.

Here, the plurality of PUCCH resources include: multiple PUCCH resources occupying different time domain symbols. Here, PUCCH resources of different time domain symbols may have different starting positions. Referring to fig. 3 or fig. 4 again, the PUCCH resources include four different PUCCH resources numbered 1, 2, 3, and 4, the time domain symbols occupied by the PUCCH resources numbered 1, 2, 3, and 4 are respectively corresponding to 10, 2, and 4, and the PUCCH resources of different time domain symbols are configured, so that the UE can select the PUCCH resources more flexibly, for example, the UE can flexibly select the PUCCH resources with more time domain symbols to send the HARQ-ACK message. In an embodiment, a plurality of PUCCH resource sets including a plurality of PUCCH resources occupying different time domain symbols are generated according to the bit number required for transmitting uplink control information UCI; the method for configuring the same Physical Uplink Control Channel (PUCCH) resource set for the subslots contained in one time slot comprises the following steps: the same PUCCH resource set is selected from a plurality of PUCCH resource sets for subslots included in one slot.

here, discarding the first PUCCH resource includes: the entire first PUCCH resource is discarded, or a portion of the first PUCCH resource is discarded.

As shown in fig. 3, an embodiment of the present disclosure provides a schematic diagram that a whole PUCCH resource in a resource configuration method is discarded, where each slot includes 2 subslots 0 and 1. Wherein each sub-slot occupies 7 time domain symbol lengths (simplified and described as "7 symbols" in fig. 3), the corresponding PUCCH resource set includes four different PUCCH resources numbered 1, 2, 3, 4, and the time domain symbols occupied by each PUCCH resource correspond to 10, 2, 4, respectively. In the subslot1, the time domain symbol (10 symbol) occupied by the PUCCH resource with number 1 in the PUCCH resource set exceeds the slot boundary, and the entire PUCCH resource configuration with number 1 is discarded, that is, the entire physical resource mapped by the PUCCH resource configuration with number 1 is no longer used for data or information transmission (the discarded PUCCH resource with number 1 is shown by "X" in fig. 3).

As shown in fig. 4, an embodiment of the present disclosure provides a schematic diagram that a part of PUCCH resources in a resource configuration method is discarded, where each slot includes 2 subslots 0 and 1. Wherein each sub-slot occupies 7 time domain symbol lengths (simplified to "7 symbols" in fig. 4), the PUCCH resource set includes four different PUCCH resources numbered 1, 2, 3, and 4, and the time domain symbols occupied by each PUCCH resource correspond to 10, 2, and 4, respectively. In the subslot1, a time domain symbol (10 symbol) occupied by PUCCH resource numbered 1 in the PUCCH resource set exceeds a slot boundary, a part of configuration of PUCCH resource numbered 1 is discarded, that is, a part of physical resource mapped by the part of configuration of PUCCH resource numbered 1 is no longer used for data or information transmission (the partially discarded PUCCH resource numbered 1 configuration is shown by "X" in the figure), which is equivalent to that the time domain symbol occupied by PUCCH resource is truncated.

It can be known that, in the embodiment of the present application, discarding the first PUCCH resource includes: the entire first PUCCH resource is discarded, or a portion of the first PUCCH resource is discarded. This enables PUCCH resources occupying more time domain symbols to be configured, which reduces the impact of limited coverage of PUCCH channels occupying fewer time domain symbols, which is caused by the UE being able to use PUCCH occupying fewer time domain symbols when uplink power is limited or uplink quality is poor. According to the embodiment of the application, the uplink coverage of the PUCCH can be improved, and the flexibility of the PUCCH resource in time domain configuration is improved.

Here, when a time domain symbol occupied by one PUCCH resource exceeds a slot boundary, discarding a part of the PUCCH resource includes: and when the time domain symbol occupied by one PUCCH resource exceeds the boundary of the slot, discarding the time domain symbol of which the PUCCH resource exceeds the boundary of the slot.

referring to fig. 4 again, the time domain symbol occupied by the PUCCH resource numbered 1 is 10, which exceeds the slot boundary, and at this time, the time domain symbol occupied by the PUCCH resource exceeding the slot boundary may be discarded, that is, the time domain symbol occupied by the PUCCH resource is truncated from 10 to 7 (10 minus 3), which may ensure that the start position and the end position corresponding to the time domain symbol occupied by the PUCCH resource are included in one slot.

As shown in fig. 5, another embodiment of the present disclosure provides a resource allocation method, where the method includes:

step S510: configuring a plurality of sets of PUCCH resource sets for subslots contained in one time slot; wherein, each set of PUCCH resource sets is suitable for one or more subslots contained in the time slot, and the PUCCH resource sets comprise: one or more PUCCH resources.

the PUCCH resource may be a set of configuration parameters for which the PUCCH resource is configured. The time domain symbols occupied by different PUCCH resources may be different, so that the time domain symbols corresponding to the PUCCH resources are more diverse, and the terminal UE can flexibly select the PUCCH resources of different time domain symbols, for example, the terminal UE sends the HARQ-ACK message based on the PUCCH resources of different time domain symbols.

Here, configuring multiple sets of PUCCH resource sets, each set of PUCCH resource set being applicable to one or more subslots included in one slot, may be to configure each set of PUCCH resource set, and specify to which subslots in the slot each set of PUCCH resource set is applicable. The description is given by taking an example that multiple sets of PUCCH resource sets include PUCCH resource set numbered 1 and PUCCH resource set numbered 2, and a slot includes subslot0, subslot1, subslot2, and subslot 3: it may be specified that PUCCH resource set number 1 is applicable to subslot1, and PUCCH resource set number 2 is applicable to subslot0, subslot2, and subslot 3. In the embodiment of the present disclosure, each set of PUCCH resource sets is applicable to one or more sub-slots included in one slot, and compared with a case where each sub-slot needs to be configured with a different PUCCH resource set independently, the resource set can be saved. Meanwhile, the configuration information overhead when the resource sets are configured independently is reduced.

here, configuring a plurality of sets of PUCCH resource sets for subslots included in one slot further includes: the same PUCCH resource set is set for subslots having the same number of time domain symbols included in one slot.

Here, in the unequal sub-slot division manner, one slot may include sub-slots with different time domain symbol numbers, for example, 3/4/3/4 sub-slots (that is, the time domain symbol lengths of the sub-slots are respectively 3, 4, 3, and 4) division manner. In the above partitioning scheme, two sub-slots occupying 4 time domain symbol lengths may be configured to share one set of PUCCH resource sets (configuration a), and two sub-slots occupying 3 time domain symbol lengths may be configured to share one set of PUCCH resource sets (configuration B). In configuration a, a PUCCH resource set of 4 time domain symbols may be configured; in configuration B, a PUCCH resource set of 4 time domain symbols may be configured. Compared with the method that each sub-slot is independently configured with different PUCCH resource sets, the number of the needed PUCCH resource sets is reduced, the resource sets can be saved, and the configuration information overhead when the resource sets are configured is reduced.

Further, the present disclosure also provides 2 specific embodiments to further understand the PUCCH resource configuration method provided by the embodiments of the present disclosure.

Example 1:

a specific embodiment of the present disclosure provides a resource allocation method, including:

Step S610: and configuring the same physical uplink control channel resource set for the sub-time slots contained in one time slot.

Here, the PUCCH resource set includes: one or more PUCCH resources. Here, a plurality of sub-slots in a slot share one set of PUCCH resources, that is, different sub-slots, whose PUCCH resources are the same.

Step S620: when a time domain symbol occupied by a first PUCCH resource in the PUCCH resource set exceeds a slot boundary, the whole first PUCCH resource is discarded or a part of the first PUCCH resource is discarded.

Here, although the PUCCH resources are the same, for a specific sub-slot, if the length of a time domain symbol occupied by a certain PUCCH resource exceeds a slot boundary, the PUCCH resource is discarded. Two ways may be included:

mode 1: referring to fig. 3 again, for a specific sub-slot, if the length of the time domain symbol occupied by a PUCCH resource in a PUCCH resource set exceeds the slot boundary, the PUCCH resource is entirely discarded.

Mode 2: referring to fig. 4 again, for a specific sub-slot, if the length of the time domain symbol occupied by a PUCCH resource in a PUCCH resource set exceeds the slot boundary, the portion of the PUCCH resource that exceeds the boundary is discarded, which is equivalent to the PUCCH resource being truncated.

In this embodiment, on one hand, the same PUCCH resource sets are configured for sub-slots included in one slot, so that it is not necessary to configure a respective PUCCH resource set for each sub-slot, and thus when configuration information of the PUCCH resource set is issued, it is not necessary to issue configuration information of the PUCCH resource set for each sub-slot, thereby reducing overhead of issuing configuration information. On the other hand, when the time domain symbol occupied by the PUCCH resource in the PUCCH resource set exceeds the boundary of the time slot, the whole PUCCH resource is discarded or a part of the PUCCH resource is discarded, but the PUCCH resource configuration is discarded when the time domain symbol occupied by the PUCCH resource exceeds the boundary of one sub-time slot, so that the PUCCH resource occupying more time domain symbols can be configured, and the influence of limited coverage of the PUCCH channel occupying less time domain symbols, which is caused by that the UE can only use the PUCCH occupying less time domain symbols when the uplink power is limited or the uplink quality is poor, is reduced. The uplink coverage of the PUCCH can be improved, and the flexibility of the PUCCH resource in time domain configuration is improved.

In some embodiments, the maximum code rate of the PUCCH resource may be configured in PUCCH Configuration information (Configuration) in the RRC layer, and the code rate on the PUCCH resource may not exceed this code rate. In the configuration of the PUCCH resource set, the maximum supportable Uplink Control Information (UCI) bit number of the resource set is configured. Each PUCCH resource in the set of resources can carry the maximum allowed number of UCI bits. Thus, when the base station determines the PUCCH resource set to be selected according to the UCI bit number, it is possible to flexibly select any PUCCH resource in the resource set according to specific requirements (for example, factors such as processing delay, Orthogonal Frequency Division Multiplexing (OFDM), CP-OFDM, and whether there is multiuser Multiplexing). Then, if the PUCCH resource is truncated because the PUCCH resource exceeds the boundary of the slot in the case that the sub-slot is configured, this may result in the case that the truncated PUCCH resource may not carry the maximum allowed UCI bit number configured by the original RRC. That is to say, under the condition that the shortened PUCCH resource satisfies the maximum code rate, the number of UCI bits that can be carried is smaller than the maximum allowed UCI bits configured in the PUCCH resource set to which the PUCCH resource belongs. Then the base station needs to specifically calculate the number of loadable UCI bits of the truncated PUCCH resource when selecting a specific PUCCH resource. Therefore, the mode 1 is a more suitable mode. In mode 1, the existing PUCCH resource selection and determination procedures can still be used.

Example 2:

another specific embodiment of the present disclosure provides a resource allocation method, including:

Step S710: configuring a plurality of sets of PUCCH resource sets for subslots contained in one time slot; wherein, each set of PUCCH resource sets is suitable for one or more subslots contained in the time slot, and the PUCCH resource sets comprise: one or more PUCCH resources.

Here, sets of PUCCH resource sets are configured, and for each set of PUCCH resource sets, which sub-slots in a slot it applies to is specified. In this embodiment, the time domain symbol lengths included in the divided 4 sub-slots are respectively 3, 4, 3, and 4, and for 2 sub-slots of 4 symbols, a set of PUCCH resource sets may be shared and configured correspondingly as a; for 2 3-symbol sub-slots, a set of PUCCH resource sets may be shared, corresponding to configuration B. In configuration a, PUCCH resources occupying 4 time domain symbols may be configured; in configuration B, PUCCH resources occupying 4 time domain symbols may be configured.

In this embodiment, each set of PUCCH resource sets is applicable to multiple sub-slots included in one slot, and compared with the case where each sub-slot needs to be configured with a different PUCCH resource set independently, the resource set can be saved. Meanwhile, the configuration information overhead when the resource sets are configured independently is reduced.

as shown in fig. 6, a schematic structural diagram of a PUCCH resource configuration device according to an embodiment of the present disclosure is provided, where the apparatus according to the embodiment of the present disclosure includes:

A first configuring module 61, configured a same PUCCH resource set for subslots included in one timeslot, where the PUCCH resource set includes: one or more PUCCH resources;

Here, the first configuring module 61 is further configured to configure the plurality of PUCCH resources to include a plurality of PUCCH resources occupying different time domain symbols.

Here, the first configuration module 61 is further configured to discard the entire first PUCCH resource, or discard a part of the first PUCCH resource.

Here, the processing module 62 is further configured to discard the time domain symbol of the PUCCH resource exceeding the boundary of the slot when the time domain symbol occupied by one PUCCH resource exceeds the boundary of the slot.
