Description

Resource indication method, resource determination method and equipment

Technical Field

The invention relates to the technical field of mobile communication, in particular to a resource indicating method, a resource determining method and equipment.

Background

In the technical discussion of a 5G New air interface (NR, New Radio), a hybrid Physical Uplink Control Channel (PUCCH) indication method is proposed, which is applied to a single PUCCH to feed back hybrid automatic repeat request acknowledgement (HARQ-ACK) information of a single Physical Downlink Shared Channel (PDSCH), and a specific method includes the following steps:

1) using RRC signaling to indicate a resource set, wherein the RRC signaling needs to indicate specific configuration parameters, and obtaining corresponding PUCCH resource sets according to the configuration parameters;

2) one of the 4 resource subsets is indicated using PUCCH resource indication information (PUCCH resource Indicator) of 2 bits. When the PUCCH resource set contains 8 PUCCH resources, one resource subset contains 2 PUCCH resources, and when one set contains 4 resources, each resource subset contains 1 PUCCH resource;

3) when a resource subset contains 2 resources, an implicit method can be used to indicate a particular resource. For example, a Control Channel Element (CCE) index used to schedule the beginning of the PDCCH is used to map one resource in the resource subset, such as an odd index mapped to the 1 st resource and an even index mapped to the second resource.

The above-described method may be applied to ACK/NACK information transmission of a single PDSCH, but is still not applicable to ACK/NACK information feedback of multiple PDSCHs.

When ACK/NACK information of multiple PDSCHs may need to be fed back in one PUCCH, each time, due to PDCCH loss, a terminal (UE) has ambiguity about an indication of the base station through the PDCCH, for example, the base station transmits 3 PDCCHs, but the UE receives only 2 PDCCHs, so that resources of the PUCCH corresponding to the UE are not consistent with actually allocated resources of the base station, and thus, ACK/NACK information transmitted by the UE is not received by the base station, thereby causing system operation confusion.

Therefore, a method applicable to PUCCH resource indication when a plurality of PDSCHs correspond to a single PUCCH feedback is needed.

In the embodiment of the present invention, the Base Station may be a Macro Base Station (Macro Base Station), a micro Base Station (Pico Base Station), a Node B (3G mobile Station), an enhanced Base Station (eNB), a Home enhanced Base Station (Femto eNB or Home eNode B or Home eNB or HeNB), a relay Station, an access point, an RRU (Remote Radio Unit), an RRH (Remote Radio Head), a network side Node in a 5G mobile communication system, such as a Central Unit (CU, Central Unit) and a Distributed Unit (DU, Distributed Unit), and the like.

The embodiment of the invention provides a specific resource indication method and a resource determination method of PUCCH resources aiming at a scene that a plurality of PUCCH-scheduled PDSCHs need to perform HARQ-ACK information feedback on the same PUCCH. For example, fig. 1 shows 3 PDCCHs and 3 PDSCHs, each PDCCH schedules one PDSCH, and the scheduling relationship is indicated by an arrow between the PDCCH and the PDSCH in fig. 1. When 3 PDSCHs in fig. 1 need to be fed back on the same PUCCH, to avoid the problem of system operation abnormality caused by a certain PDCCH not being received by a terminal, a solution of the following embodiment is proposed. It should be noted that the 3 PDCCHs in fig. 1 are located at different positions in the time domain, for example, in different subframes. Of course, multiple PDCCHs may also be located at different positions on the frequency domain, e.g., in different subcarriers, or may be located at different time and frequency domain positions.

< example one >

Referring to fig. 2, an embodiment of the present invention provides a resource indication method for hybrid automatic repeat request acknowledgement (HARQ-ACK) information, where the method may be applied to a network side device, such as a base station, as shown in fig. 2, and the method includes:

step 21, configuring a resource set containing a plurality of PUCCH resources for carrying bits of HARQ-ACK information of a PDSCH for the terminal, wherein the length of the bits is determined according to the maximum number of the PDSCH which is configured in advance in the same PUCCH resource for carrying out HARQ-ACK information transmission, or according to the maximum number of the PDCCH which is configured in advance in correspondence to the same PUCCH resource for carrying out HARQ-ACK information transmission.

Here, the network side device may configure the resource set for the terminal through RRC signaling or the like. Related configuration parameters may be included in the RRC signaling, and according to the configuration parameters, the terminal may obtain a corresponding PUCCH resource set. The resource set typically includes a plurality of PUCCH resources, for example, 4 or 8 PUCCH resources, and so on. In this embodiment, the length of the bits of the PUCCH resource used for carrying the HARQ-ACK information of the PDSCH is determined by the maximum number (assumed to be x) of PDSCHs that are pre-configured in the same PUCCH resource for HARQ-ACK information transmission, that is, the length is usually a fixed value, even if the actual number of PDSCHs that are performing HARQ-ACK information transmission on the PUCCH resource is smaller than the maximum number. Generally, one PDSCH is scheduled through one PDCCH, and therefore, the length of the bit may also be determined according to the maximum number (assumed to be y) of PDCCHs configured in advance for HARQ-ACK information transmission corresponding to the same PUCCH resource. Here, x is y. It should be noted that the PDCCH for performing HARQ-ACK information transmission corresponding to the same PUCCH resource means that the HARQ-ACK information of the PDSCH scheduled by the PDCCH is fed back on the same PUCCH resource.

And step 22, indicating a PUCCH resource subset or a single PUCCH resource used for feeding back HARQ-ACK information in the resource set to the terminal through PUCCH resource indication information in the PDCCH, wherein a group of PDCCHs which feed back corresponding to the same PUCCH resource have the same PUCCH resource indication information, and the PUCCH resource subset comprises at least two PUCCH resources.

Here, in the embodiment of the present invention, the PDCCHs of the same group have the same PUCCH resource indication information, where the PDCCHs of the same group include at least two PDCCHs, and the PDSCH scheduled by each PDCCH is configured to feed back HARQ-ACK information on the same PUCCH resource.

Through the above steps, in the embodiment of the present invention, when the PUCCH resource is allocated by the network side device, a group of PDCCHs which are fed back corresponding to the same PUCCH resource are enabled to have the same PUCCH resource indication information, in this way, when the network side equipment transmits a plurality of PDCCHs in the same set of PDCCHs, even if some/some of the PDCCHs are not received by the terminal, since their PUCCH resource indication information is the same, therefore, the terminal can still determine the PUCCH resource for HARQ-ACK information feedback according to any one of the received PDCCHs, moreover, the PUCCH resource determined by the terminal is consistent with the PUCCH resource actually allocated by the network side equipment, therefore, the network side equipment can receive the HARQ-ACK information sent by the terminal on the PUCCH resource position, the success rate of receiving the ACK/NACK information by the network side equipment is improved, and the working stability of the system is improved.

In this embodiment of the present invention, when the PUCCH resource indication information indicates a PUCCH resource subset used for feeding back HARQ-ACK information in the resource set, if the PUCCH resource subset includes at least two PUCCH resources, the PUCCH resource used for feeding back HARQ-ACK information in the PUCCH resource subset may be determined according to a pre-agreed mapping manner.

Taking 2-bit PUCCH resource indication information as an example, the resource set includes 8 PUCCH resources, and the PUCCH resource indication information may indicate 4 PUCCH resource subsets, each PUCCH resource subset including 2 PUCCH resources. At this time, mapping may be performed according to the parity of the maximum number in the foregoing, for example, as one implementation, when the maximum number is an odd number, an odd PUCCH resource in the PUCCH resource subset is used for feeding back HARQ-ACK information; and when the maximum number is an even number, the even number PUCCH resources in the PUCCH resource subset are used for feeding back HARQ-ACK information. As another implementation, when the maximum number is an even number, odd PUCCH resources in the PUCCH resource subset are used for feeding back HARQ-ACK information; and when the maximum number is an odd number, even PUCCH resources in the PUCCH resource subset are used for feeding back HARQ-ACK information.

For another example, 4 PUCCH resources are included in the resource set, and 2-bit PUCCH resource indication information may indicate a single PUCCH resource in the resource set for feeding back HARQ-ACK information.

In the method for indicating resources of HARQ-ACK-codebook according to the embodiment of the present invention, the maximum number is usually a relatively stable value, so the method for indicating resources according to the embodiment of the present invention may be referred to as a semi-static HARQ-ACK-codebook mode. In this embodiment of the present invention, the network side device may further send, to the terminal, a configuration parameter (e.g., a high-layer parameter HARQ-ACK-codebook) for indicating a semi-static HARQ-ACK-codebook mode, and a configuration parameter for indicating a maximum timing parameter value and a minimum timing parameter value for the HARQ-ACK feedback. After the terminal obtains the configuration parameters, the terminal may derive the specific value of the maximum quantity according to the maximum time sequence parameter value and the minimum time sequence parameter value.

Referring to fig. 3, an embodiment of the present invention further provides a resource determining method for harq acknowledgement information, where the resource determining method may be applied to a terminal side, and as shown in fig. 3, the method includes:

and step 31, determining a resource set which is configured for the terminal by the network and comprises a plurality of PUCCH resources, wherein the PUCCH resources are used for bearing bits of the HARQ-ACK information of the PDSCH, and the length of the bits is determined according to the maximum number of the PDSCH which is configured in advance in the same PUCCH resource for carrying out HARQ-ACK information transmission, or is determined according to the maximum number of the PDCCH which is configured in advance in correspondence to the same PUCCH resource for carrying out HARQ-ACK information transmission.

Here, the network side device may configure the resource set for the terminal through RRC signaling or the like. The terminal acquires relevant configuration parameters carried in the RRC signaling by receiving the RRC signaling sent by the network, and according to the configuration parameters, the terminal can determine the PUCCH resource set configured by the network.

And step 32, receiving a PUCCH resource subset or a single PUCCH resource used for feeding back HARQ-ACK information in the resource set indicated to the terminal by the network through PUCCH resource indication information in the PDCCH, wherein a group of PDCCHs which feed back corresponding to the same PUCCH resource have the same PUCCH resource indication information, and the PUCCH resource subset comprises at least two PUCCH resources.

Here, the same set of PDCCHs has the same PUCCH resource indication information, where the same set of PDCCHs includes at least two PDCCHs, and the PDSCH scheduled by each PDCCH is configured to feed back HARQ-ACK information on the same PUCCH resource.

And step 33, feeding back the HARQ-ACK information according to the PUCCH resource subset or single PUCCH resource used for feeding back the HARQ-ACK information in the resource set indicated by the network.

Here, the terminal may determine a specific PUCCH resource and perform feedback of the HARQ-ACK information according to a PUCCH resource subset or a single PUCCH resource used for feeding back the HARQ-ACK information in the resource set indicated by the network.

Specifically, when the PUCCH resource indication information indicates a PUCCH resource subset for feeding back HARQ-ACK information in the resource set, a single PUCCH resource for feeding back HARQ-ACK information in the PUCCH resource subset is determined according to a preset mapping manner.

For example, when the resource set includes 8 PUCCH resources, the PUCCH resource subsets have 4, and each PUCCH resource subset includes 2 PUCCH resources, odd or even resources of the PUCCH resource subsets may be mapped according to the maximum number of parities. Specifically, as an implementation manner, when the maximum number is an odd number, feeding back HARQ-ACK information through odd PUCCH resources in the PUCCH resource subset; and when the maximum number is an even number, feeding back HARQ-ACK information through even PUCCH resources in the PUCCH resource subset. As another implementation, when the maximum number is even, feeding back HARQ-ACK information through odd PUCCH resources in the PUCCH resource subset; and when the maximum number is an odd number, feeding back HARQ-ACK information through even PUCCH resources in the PUCCH resource subset.

For another example, when the resource set includes 4 PUCCH resources, 2-bit PUCCH resource indication information may indicate a single PUCCH resource in the resource set. At this time, the terminal may determine a single PUCCH resource for feeding back the HARQ-ACK information directly according to the PUCCH resource indication information.

In addition, in the embodiment of the present invention, the terminal may further receive a configuration parameter sent by the network and used for indicating a semi-static HARQ-ACK-codebook mode, and a configuration parameter used for indicating a maximum timing parameter value and a minimum timing parameter value of the HARQ-ACK feedback. By receiving the configuration parameters, the terminal can determine that the current mode is the semi-static HARQ-ACK-codebook mode, and derive the maximum number according to the maximum time sequence parameter value and the minimum time sequence parameter value.

Through the steps, the terminal side can determine the PUCCH resources consistent with the actually distributed resources of the network side to feed back the HARQ-ACK information, so that the receiving success rate of the network side equipment to the ACK/NACK information is improved, and the working stability of the system is improved.

Based on the method, the embodiment of the invention also provides equipment for implementing the method.

< example two >

Referring to fig. 8, an embodiment of the present invention provides a method for indicating resources of hybrid automatic repeat request acknowledgement (HARQ-ACK) information, where the method may be applied to a network side device, such as a base station, and as shown in fig. 8, the method includes:

step 81, configuring a resource set containing a plurality of PUCCH resources for the terminal.

Here, the PUCCH resource is used to carry bits of HARQ-ACK information of the PDSCH. In this embodiment, the length of the bit is variable, so that the network side can configure resources of corresponding size according to the requirement of HARQ-ACK feedback, thereby saving the resource overhead of HARQ-ACK information transmission. The set of resources may include a plurality of PUCCH resource subsets, each subset may include at least 1 PUCCH resource.

Step 82, a PUCCH resource subset used for feeding back the HARQ-ACK information of the PDSCH in the resource set is indicated to the terminal through PUCCH resource indication information in the PDCCH, and the PUCCH resource subset comprises at least two PUCCH resources; when the HARQ-ACK information of at least two PDSCHs is fed back on the same PUCCH resource, the PUCCH resource used for feeding back the HARQ-ACK information in the PUCCH resource subset is determined according to the attribute of a control channel unit (CCE) corresponding to the PDCCH sent in a feedback window, and the starting time and the ending time of the feedback window are determined by the time sequence parameter indicated by network side RRC signaling or DCI information.

Here, from the perspective of the network side, considering that the terminal may lose the PDCCH, the network side may allocate a plurality of PUCCH resources, each of which is indicated by a corresponding PDCCH, but for the terminal, when feeding back HARQ-ACK information, ACK/NACK information is fed back on the corresponding PUCCH resource according to the indication of the last received PDCCH.

Here, the PUCCH resource indication information is used to indicate a certain subset of resources in the resource set. For example, when there are 4 PUCCH resource subsets, a certain subset of the 4 PUCCH resource subsets may be indicated by one 2-bit indication information.

Here, the feedback window is indicated to the terminal by the network side device through the RRC signaling or the timing parameter indicated by the DCI information. And HARQ-ACK information of PDSCH scheduled by a plurality of PDCCHs in the feedback window needs to be fed back on the same PUCCH resource. For the terminal, feeding back the HARQ-ACK information of the PDSCH scheduled by the PUCCHs for the PUCCHs received in the feedback window. And the terminal determines one PUCCH resource in the PUCCH resource subset according to the control channel element CCE attribute corresponding to the last PDCCH received in the feedback window. The last PDCCH received in the feedback window may specifically be the PDCCH with the latest reception time in the feedback window. If there are a plurality of PDCCHs that are the latest in time, the PDCCH with the last (e.g., the largest) carrier number may be used among the plurality of PDCCHs.

Through the steps, the method and the device can simply and definitely indicate the plurality of PDSCHs to feed back the HARQ-ACK information on the single PUCCH to the terminal.

Further, in the embodiment of the present invention, the PUCCH resource indication information of multiple PDCCHs in the same feedback window may be the same. Of course, the PUCCH resource indication information of multiple PDCCHs within the same feedback window may not be completely the same, i.e., there are different PUCCH resource indication information. In the embodiment of the present invention, each PDCCH in the same feedback window may have independent PUCCH resource indication information, and at this time, PUCCH resource indication information of all PDCCHs in the same feedback window may be the same, or PUCCH resource indication information of part PDCCHs may be the same, or PUCCH resource indication information of each PDCCH is different.

Optionally, the resource set configured in step 81 may include 8 PUCCH resources, and the PUCCH resource subset includes 2 PUCCH resources; the CCE attribute is the parity of the index number of the initial CCE or the parity of a numerical value obtained after the index number of the initial CCE is divided by the aggregation level.

For example, when the CCE attribute is odd, an odd PUCCH resource in the PUCCH resource subset is used for feeding back HARQ-ACK information; and when the CCE attribute is even, the even PUCCH resources in the PUCCH resource subset are used for feeding back HARQ-ACK information. For another example, when the CCE attribute is even, odd PUCCH resources in the PUCCH resource subset are used for feeding back HARQ-ACK information; and when the CCE attribute is an odd number, even PUCCH resources in the PUCCH resource subset are used for feeding back HARQ-ACK information.

In addition, in the embodiment of the present invention, the network side device may further indicate the start time and the end time of the feedback window to the terminal through RRC signaling or DCI information, so as to help the terminal determine the position of the feedback window.

In order to improve the success rate of receiving ACK/NACK information by the network side device and improve the stability of system operation, in the embodiment of the present invention, the network side device may further reserve N PUCCH resources for the terminal, where the N PUCCH resources correspond to the last N PDCCHs transmitted in the feedback window one to one, and each PUCCH resource is determined according to PUCCH resource indication information in a corresponding PDCCH and a CCE attribute corresponding to the corresponding PDCCH, and N is an integer greater than or equal to 2.

For example, 2 PUCCH resources are reserved for the terminal, one for each of the last 2 PDCCHs within the feedback window. The reserved 1 st PUCCH resource corresponds to the 1 st last PDCCH sent in the feedback window; the reserved 2 nd PUCCH resource corresponds to the 2 nd last PDCCH transmitted within the feedback window. Each reserved PUCCH resource is used for determining a PUCCH resource subset according to PUCCH resource indication information of a corresponding PDCCH, then a specific single PUCCH resource is determined from the PUCCH resource subset according to CCE attribute of the corresponding PDCCH, and if the CCE attribute is odd, the odd PUCCH resources in the PUCCH resource subset are used as reserved PUCCH resources; and when the CCE attribute is an even number, taking the even number PUCCH resources in the PUCCH resource subset as reserved PUCCH resources.

When at least two PUCCH resources are reserved, because the terminal may feed back HARQ-ACK information on any reserved resource, the network side device may perform blind detection on the reserved N PUCCH resources respectively to receive the HARQ-ACK information sent by the terminal.

The network side equipment reserves at least two PUCCH resources, so that the terminal can utilize the reserved PUCCH resources to feed back the HARQ-ACK information aiming at the PDCCH received in the feedback window as long as the terminal receives any PDCCH corresponding to the reserved PUCCH resources, thereby improving the receiving success rate of the network side equipment on the ACK/NACK information and improving the working stability of the system.

Referring to fig. 9, an embodiment of the present invention further provides a resource determining method for harq acknowledgement information, where the resource determining method may be applied to a terminal side, and as shown in fig. 9, the method includes:

step 91, determining a resource set containing a plurality of PUCCH resources configured by the network for the terminal.

And step 92, receiving a first PUCCH resource subset used for feeding back HARQ-ACK information in the resource set indicated by the terminal through PUCCH resource indication information in the PDCCH by the network.

Step 93, when feeding back HARQ-ACK information of at least two PDSCHs on the same PUCCH resource, determining one PUCCH resource in the first PUCCH resource subset according to the CCE attribute of the last PDCCH received in the feedback window, where the start time and the end time of the feedback window are determined by a timing parameter indicated by an RRC signaling or DCI information sent by the network.

Here, the CCE attribute is parity of an index number of the starting CCE, or parity of a value obtained by dividing the index number of the starting CCE by the aggregation level.

For example, when the resource set includes 8 PUCCH resources and the PUCCH resource subset includes 2 PUCCH resources, it may be determined that a certain PUCCH resource in the PUCCH resource subset is used for feeding back HARQ-ACK information according to the CCE attribute. For example, when the CCE attribute is an odd number, it is determined that an odd PUCCH resource in the PUCCH resource subset is used for feeding back HARQ-ACK information; and when the CCE attribute is even, determining that even PUCCH resources in the PUCCH resource subset are used for feeding back HARQ-ACK information. For another example, when the CCE attribute is an even number, odd PUCCH resources in the PUCCH resource subset are determined to be used for feeding back HARQ-ACK information; and when the CCE attribute is an odd number, determining that even PUCCH resources in the PUCCH resource subset are used for feeding back HARQ-ACK information.

And step 94, feeding back HARQ-ACK information according to the determined PUCCH resource.

Here, HARQ-ACK information of a PDSCH scheduled by a PDCCH received within the feedback window will be transmitted through the determined single PUCCH resource.

Furthermore, in the embodiment of the present invention, the terminal may further receive the start time and the end time of the feedback window, which are indicated to the terminal by the network through RRC signaling or DCI information, so as to determine the range of the feedback window according to the start time and the end time.
