Various embodiments of the present invention will be described below with reference to the drawings. These embodiments are exemplary only, and are not a limitation on the present invention.

Example 1

This embodiment provides a method for configuring uplink resources, and the method is applied to a network device. FIG. 2 is a schematic diagram of an uplink resource configuration method according to this embodiment. Referring to FIG. 2, the method includes:

Step 201: The network device sends first configuration information to the terminal device, where the first configuration information configures time-frequency resources for sending feedback information (HARQ-ACK) of a hybrid automatic retransmission request for the first service, and / or, The first configuration information is configured not to send the HARQ-ACK of the first service; wherein the priority of the first service is higher than the priority of the second service.

In this embodiment, for a specific service (the above-mentioned first service), for example, URLLC, which has relatively high delay and reliability requirements, the network device configures corresponding time-frequency resources for HARQ-ACK feedback, or the configuration does not perform the above. The HARQ-ACK feedback is to retransmit the PDSCH, thereby ensuring the delay and reliability of the first service transmission.

In an implementation manner of this embodiment, the time-frequency resource for sending the HARQ-ACK of the first service may be preempt all or part of the bearer (or called piggyback) of the second service. Time-frequency resources of ACK. Examples of the time-frequency resource include physical uplink control channel (PUCCH) resources and / or physical uplink shared channel (PUSCH) resources.

In this embodiment, the above-mentioned first configuration information may be carried by high-level signaling (for example, preemption-PUCCH-HARQ), that is, the network equipment may configure the HARQ- that forces all or part of the second service to be carried through this high-level signaling The time-frequency resource of the ACK is not limited in this embodiment.

In this embodiment, the PUCCH resource for the HARQ-ACK carrying the second service is forcibly occupied.

The network device may also send downlink control information (referred to as the first control information) to the terminal device, and the first control information is used to instruct the terminal device to drop all or part of the HARQ-ACK information bits of the second service in order to occupy the The PUCCH resource of the HARQ-ACK carrying the second service. Therefore, the terminal device can discard the ACK or NACK (abbreviated as A / N) originally sent on the resource, and send the newly generated A / N. The originally planned A / N is the HARQ-ACK of the second service, which can also be called the original HARQ-ACK; the newly generated A / N is the HARQ-ACK of the first service, which can also be called New HARQ-ACK.

In this embodiment, the PUSCH resource for HARQ-ACK carrying the second service is forcibly occupied.

The network device may also send the second configuration information to the terminal device. For the PUSCH resource that is preempted and carries the HARQ-ACK of the second service, if the HARQ-ACK of the first service is sent on the PUSCH resource, the second The configuration information configures a resource allocation parameter (β _offset ), where the resource allocation parameter indicates a proportion of the time-frequency resource that actually carries the HARQ-ACK of the first service in the PUSCH resource. In addition, in this embodiment, the network device may also disable the configured HARQ-ACK resource allocation parameter (β _offset ) of the second service to ensure the delay and reliability of the first service transmission. The second configuration information may also be carried through higher-layer signaling.

In another implementation manner of this embodiment, the time-frequency resource of the HARQ-ACK for transmitting the first service may also be a time-frequency resource of the HARQ-ACK for multiplexing the second service. Similarly, the time-frequency resource may be a PUCCH resource and / or a PUSCH resource.

In this embodiment, the above-mentioned first configuration information may be carried by high-level signaling (for example, Multiplexing-PUCCH-HARQ), that is, a network device may configure the multiplexing of HARQ-ACK carrying the second service through the high-level signaling Time-frequency resources, this embodiment is not limited thereto.

In this embodiment, for a PUCCH resource that multiplexes the HARQ-ACK carrying the second service.

The network device may determine a HARQ-ACK codebook (codebook) according to the HARQ-ACK of the first service and the HARQ-ACK of the second service, and use the HARQ-ACK codebook to make the PUCCH resource of the HARQ-ACK of the first service and the The PUCCH resources of the HARQ-ACK of the second service are multiplexed together. Therefore, the new HARQ-ACK is multiplexed to the PUCCH resource of the original HARQ-ACK.

In one example, when determining the codebook of the HARQ-ACK, the network device may allocate more codewords to the information bits of the HARQ-ACK of the first service to further ensure the transmission reliability of the first service. This embodiment is not limited to this.

In this embodiment, for a PUSCH resource that multiplexes HARQ-ACK carrying the second service.

The network device may also send third configuration information to the terminal device. For the multiplexed PUSCH resource carrying the HARQ-ACK of the second service, the third configuration information configures the time-frequency resource carrying the HARQ-ACK of the first service and The proportion of the time-frequency resource carrying the second service HARQ-ACK in the PUSCH resource. Therefore, the new HARQ-ACK is multiplexed to the PUCCH resource of the original HARQ-ACK. The third configuration information may also be sent through high-level signaling.

In still another implementation manner of this embodiment, the time-frequency resource of the HARQ-ACK for sending the first service may also be a dedicated time-frequency resource of the HARQ-ACK of the first service. For example, a dedicated PUCCH resource or a dedicated PUSCH resource.

In this embodiment, for dedicated PUCCH resources. In one example, the start symbol of the HARQ-ACK used for sending the first service is one of at least one symbol predefined in a time slot in the dedicated PUCCH resource.

In this example, the above-mentioned dedicated PUCCH resources can be configured in a list manner.

For example, the network device may configure a list of candidate PUCCH resources (referred to as a first list) by using the foregoing first configuration information. Each line of the above first list may include at least one or any combination of the following parameters or information: PUCCH format, first symbol, duration, number of symbols, physical resource block offset (PRB) offset), and a set of initial cyclic shift indexes (set of initial CS indexes). The at least one candidate PUCCH resource is indicated through the first list. In this example, the above-mentioned first configuration information may be carried by high-level signaling (for example, predefined-PUCCH-resource-table). That is, the network device configures the foregoing first list through the high-level signaling. However, this embodiment is not limited to this, and the first list may also be predefined.

In this example, the network device may also indicate a PUCCH resource in the first list by using another high-level signaling (for example, index-PUCCH-resource). Therefore, the terminal device may use the PUCCH resource indicated by the network device as a use. Time-frequency resources for sending HARQ-ACK of the first service.

For example, the network device may also send the fourth configuration information to the terminal device, and the fourth configuration information indicates a PUCCH resource in the first list, so that the terminal device sends the first service using the PUCCH resource indicated by the fourth configuration information. HARQ-ACK. For example, the fourth configuration information may include an index of a row in the first list, so as to indicate a PUCCH corresponding to the row in the first list. The fourth configuration information may be carried through higher-layer signaling (for example, index-PUCCH-resource).

In this example, the network device may not perform the above instruction by using the fourth configuration information, but may indicate it by using downlink control information. For example, the network device may send downlink control information (referred to as second control information) to the terminal device. A PUCCH resource in the first list is indicated by the second control information, so that the terminal device sends the HARQ-ACK of the first service by using the PUCCH resource indicated by the second control information. For example, the second control information includes an index of a line in the first list, and thus indicates a corresponding PUCCH.

In this example, the above-mentioned dedicated PUCCH may also be configured not by a list, but by a priority.

For example, the network device may configure the priority of the candidate resource by using the foregoing first configuration information, and the terminal device confirms a dedicated PUCCH resource for sending the HARQ-ACK of the first service according to the priority of the candidate resource. In this example, the above-mentioned first configuration information may be carried by high-level signaling (for example, dedicated-PUCCH-HARQ-priority), that is, the network device configures the priority of the above-mentioned selected resources through the high-level signaling. However, this embodiment is not limited to this, and the priorities of the candidate resources may also be predefined.

For example, the first configuration information may configure at least one PUCCH resource and a priority of a service that can be carried on each resource, wherein a priority of the HARQ-ACK of the first service is the highest. Therefore, the terminal device may The configuration of the first configuration information uses a PUCCH resource for sending the HARQ-ACK of the first service to send the HARQ-ACK of the first service.

The configuration of the priority of the candidate resource may also include the configuration of the priorities of other services. An example is given below:

The PUCCH carrying the HARQ-ACK of the first service has the highest priority;

The PUCCH carrying HARQ-ACK of enhanced mobile broadband (eMBB) has the next highest priority;

The PUCCH carrying other uplink control information (UCI) has a third priority;

PUSCH has a fourth priority.

The configuration of the priorities of the candidate resources is just an example, and this embodiment is not used as a limitation.

In this embodiment, for dedicated PUCCH resources. In another example, the start symbol of the HARQ-ACK for sending the first service is determined by the last symbol of the PDSCH of the received first service. For example, the time domain resource used to send the HARQ-ACK of the first service may be a period of time after receiving the PDSCH.

In this example, the network device may configure the number of symbols (k) offset from the last symbol of the PDSCH that receives the first service to the symbol that sends the HARQ-ACK of the first service by using the first configuration information. Therefore, the terminal device can start sending the HARQ-ACK of the first service on the symbol s + k, where s is the last symbol of the PDSCH that received the first service. Among them, k can be determined by the specific delay requirement and the subcarrier interval of the PDSCH / PUCCH.

In this example, s + k is allowed to cross time slot boundaries. For example, if (s + k) ≥ Ns, where Ns is the total number of symbols in a time slot, the terminal device can modify the mod (s + k in the next time slot). , Ns) starts to send the HARQ-ACK of the first service.

In this example, similar to the previous example, the network device may also configure a list of candidate PUCCH resources (referred to as a second list) through the first configuration information. Each row of the second list may include at least one or any combination of the following information or parameters: the HARQ-ACK delay requirement of the first service, the subcarrier interval of the PUCCH, and the time interval from the PDSCH to the HARQ-ACK (I.e., the number of symbols) k, the format of the PUCCH, the first symbol, the duration of the number, the physical resource block offset (PRB offset), and the set of initial cyclic shift indexes ( set of initial CS indexes). The second list is used to indicate at least one PUCCH resource of the candidate. In this example, the above-mentioned first configuration information may be carried by high-level signaling (for example, predefined-PUCCH-resource-table-2), that is, the network device configures the above-mentioned second list through the high-level signaling, but this embodiment Not limited to this, the second list may also be predefined.

In this example, the network device may also indicate a PUCCH resource in the second list by using another high-level signaling (for example, index-PUCCH-resource). Therefore, the terminal device may use the PUCCH resource indicated by the network device as Time-frequency resources for sending HARQ-ACK of the first service.

For example, the network device may also send the fifth configuration information to the terminal device, and use the fifth configuration information to indicate a PUCCH resource in the second list, so that the terminal device uses the PUCCH resource to send the first configuration information to the first HARQ-ACK of the service. For example, the fifth configuration information may include an index of a line in the second list, so as to indicate a PUCCH corresponding to the line in the second list. The fifth configuration information may be carried by higher layer signaling (for example, index-PUCCH-resource).

In this example, the network device may not perform the above instruction by using the fifth configuration information, but may use the control information to indicate. For example, the network device may send downlink control information (referred to as third control information) to the terminal device. The third control information indicates a PUCCH resource in the second list, so that the terminal device uses the PUCCH resource to send the HARQ-ACK of the first service according to the indication of the third control information. For example, the third control information may include a subscript of a line in the second list above, thereby indicating a corresponding PUCCH.

In this embodiment, dedicated PUSCH resources are used. The network device may configure a parameter (referred to as a resource allocation parameter) for the terminal device to indicate a proportion of the time-frequency resource of the HARQ-ACK that actually carries the first service in the PUSCH resource.

For example, the network device may send sixth configuration information to the terminal device. For the dedicated PUSCH resource that piggybacks the HARQ-ACK of the first service, the sixth configuration information configures a resource allocation parameter (β _offset ), the resource allocation parameter. Indicates the proportion of the time-frequency resource of the HARQ-ACK that actually carries the first service in the PUSCH resource. The sixth configuration information may be carried through high-level signaling.

In this example, the network device may also be configured to send the HARQ-ACK of the first service on the PUSCH through the first configuration information. The first configuration information may be carried by higher layer signaling (for example, piggyback-PUSCH).

In this example, the network device may also configure the resource for sending the HARQ-ACK of the first service on the PUSCH through another high-level signaling (for example, beta-offset-new-HARQ), or instruct the terminal device on the PUSCH through downlink control information. A resource for sending the HARQ-ACK of the first service on the PUSCH.

For example, the network device may send seventh configuration information to the terminal device, and use the seventh configuration information to configure a resource for sending the HARQ-ACK of the first service on the PUSCH. The seventh configuration information may be carried by high-level signaling (for example, beta-offset-new-HARQ).

For another example, the network device may send control information (referred to as fourth control information) to the terminal device, and the fourth control information is used to instruct the terminal device to send the resource of the HARQ-ACK of the first service on the PUSCH.

In step 201 of this embodiment, the network device may not configure the time-frequency resource of the above-mentioned HARQ-ACK for sending the first service, but configure the terminal device not to send the HARQ-ACK of the first service. The PDSCH of a service retransmits to ensure the delay and reliability of the transmission of the first service.

Under the above configuration, the network device may also configure the terminal device with the number of retransmissions of the PDSCH of the first service and / or the resources, modulation, coding, redundancy version (RV) and other information required for retransmission. At least one.

For example, the network device may send the eighth configuration information and / or the ninth configuration information to the terminal device. The eighth configuration information configures the number of retransmissions of the PDSCH of the first service, and the ninth configuration information configures resources required for retransmission. At least one item of information such as modulation, coding, and redundancy version (RV). Therefore, the terminal device does not need to feed back the HARQ-ACK of the first service, and can also ensure the delay and reliability of the transmission of the first service. The eighth configuration information may be carried by high-level signaling (for example, Nr-PDSCH-repetition), and the ninth configuration information may be carried by high-level signaling (Resource-PDSCH-repetition). This embodiment is not limited to this.

For another example, the network device may not perform the above configuration but indicate the foregoing content through downlink control information. For example, the network device may send downlink control information (referred to as fifth control information) to the terminal device, and the fifth control information indicates At least one of the number of times of PDSCH retransmission and / or information required for retransmission, such as resources, modulation, coding, and RV. Therefore, the terminal device does not need to feed back the HARQ-ACK of the first service, and can also ensure the delay and reliability of the transmission of the first service.

For another example, when the foregoing first list and / or the foregoing second list have been configured or predefined, a line may also be added to the foregoing first list and / or the foregoing second list and set to null. (Such as a high-level signaling configuration or a downlink control information indication) to instruct the terminal device not to send the HARQ-ACK of the first service. At this time, the network device will retransmit the PDSCH of the first service.

With the method in this embodiment, the network device configures the terminal device with time-frequency resources for sending HARQ-ACK of the first service, and demodulates the HARQ-ACK of the first service sent by the terminal device on the corresponding resources, and The received ACK or NACK determines whether the PDSCH of the first service needs to be retransmitted, thereby ensuring the delay and reliability of the transmission of the first service. In addition, the network device may also be configured not to send the HARQ-ACK of the first service, and directly retransmit the PDSCH of the first service, thereby ensuring the delay and reliability of the transmission of the first service.

Example 2

The method is applied to a network device, and the content configured by the network device according to the method of Embodiment 1 (a time-frequency resource for sending HARQ-ACK of the first service or not Send the HARQ-ACK of the first service), and the same content as in Embodiment 1 will not be described repeatedly.

FIG. 3 is a schematic diagram of an uplink resource indication method according to this embodiment. As shown in FIG. 3, the method includes:

Step 301: The network device sends downlink control information (DCI) to the terminal device, and indicates the time-frequency resource of HARQ-ACK for sending the first service through the DCI, or instructs not to send the HARQ-ACK for the first service through the DCI.

In this embodiment, the DCI of the time-frequency resource for instructing to send the HARQ-ACK of the first service and the DCI of the HARQ-ACK for instructing not to send the first service act on the time in no particular order. First business.
