Description

Method and device for processing uplink feedback information

The present invention relates to the field of communications, and in particular, to a method and an apparatus for processing uplink feedback information. Background technique

Currently, when multiple carriers are configured for aggregation at the receiving end, the format of multiple carriers is usually the same, for example, Frequency Division Duplexing (FDD) or Time Division Duplexing (TDD). Carrier, which facilitates various processing during carrier aggregation. For example, when the receiving end is configured with multiple downlink and uplink carriers, the uplink feedback information sent by the receiving end in the uplink carrier may be fed back according to the timings of the primary cell (Pcell) and the secondary cell (Scell), and further limited, uplink The feedback information is sent to the network side only on the Pcell. This is beneficial to reduce the complexity of the receiving end. For example, the receiving end only needs to have the sending function of a single carrier, and does not need to support the ability to send uplink feedback information in two uplink carriers at the same time. The receiving end may be a user equipment (UE) or a relay station or the like.

It is assumed that two downlink carriers and two uplink carriers are configured for the receiving end, and all are in FDD mode. Then, when the receiving end needs to feed back the feedback information of the downlink carrier Scell, the receiving end sends the feedback information in the uplink carrier Pcell. For the receiving end, since the timings of the downlink carrier and the uplink carrier are aligned, the UE downlink Scell corresponds to The uplink feedback information can be sent to the base station in the uplink Pcell aligned subframe of the UE without affecting the timing relationship of the uplink feedback information.

With the further evolution of the Long Term Evolution (LTE) technology, FDD and TDD aggregation are proposed. For example, two downlink carriers are configured for the receiving end, namely FDD and TDD modes, and then two uplink carriers are configured for the receiving end, respectively FDD. And in the TDD mode, the TDD carrier is the same as the downlink TDD carrier because the downlink and uplink of the TDD are on the same carrier. In this way, according to the existing protocol, when the receiving end sends the uplink feedback information, it needs to send in the subframe in the uplink Pcell. However, if the TDD carrier is configured as the uplink Pcell of the receiving end and the uplink feedback information transmission time corresponds to the downlink subframe of the TDD on the Pcell, how to handle the receiving end and how to handle the network side, there is no specific Technical Support.

In addition, because the receiving end is simultaneously difficult to transmit in multiple uplink carriers, the actual effect is poor. Therefore, for a certain period of time, most of the receiving ends do not have the capability of transmitting data on multiple uplink carriers at the same time. On the other hand, how to better support multi-carrier aggregation, especially when TDD is Pcell in TDD and FDD aggregation, there is no specific technical support at present.

The subframes in which the uplink Pcell and the uplink Scell send uplink feedback information are time-aligned, and the receiving end needs to transmit uplink feedback information on the uplink Pcell and the uplink Scell carrier at the same time.

The uplink feedback information is transmitted through one or more of the following channels: PUCCH, PUSCH. The uplink feedback information includes one or more of the following: ACK/NACK, SR, CSI.

The base station receives the uplink feedback information included in the uplink Pcell and the uplink Scell carrier only in the uplink Pcell carrier of the receiving end, and includes: receiving the uplink feedback information by using the PUCCH format 3 in the uplink Pcell.

On the base station side, when multiple carriers are configured for aggregation on the receiving end, the base station can allocate resources for uplink feedback information to the receiving end according to the following manner:

When the base station learns that the receiving end sends the uplink feedback information in the uplink Pcell and the uplink Scell carrier, the base station allocates resources to the receiving end, and the resource is used to transmit the uplink feedback included in the uplink Pcell and the uplink Scell carrier.

When the base station learns that the receiving end sends the uplink feedback information in the uplink Pcell and the uplink Scell carrier, the base station may also delete the resource used by the receiving end to send the uplink feedback information in the uplink Scell. The application of technical means to solve technical problems, and the realization of the technical effects can be fully understood and implemented.

When multiple carriers are configured for aggregation on the receiving end, the receiving end needs to be on the uplink Pcell and When the uplink feedback information is sent in the Scell carrier, the receiving end may send the uplink feedback information in the following manner:

When the subframes of the uplink feedback information sent by the receiving end in the uplink Pcell and the uplink Scell carrier are aligned, that is, when the subframes are in the same time period, the receiving end sends the uplink feedback information in the uplink Pcell carrier and the uplink Scell carrier. Transmitted by the uplink Pcell carrier. Here, the subframe is aligned, and the receiving end needs to simultaneously perform uplink data transmission in the uplink Pcell and the uplink Scell. The subframes may be strictly aligned by arranging subframes between the uplink carriers, or the range of error of the alignment may be given, which may be given by an experiment of carrier switching at the receiving end.

When the receiving end sends the uplink feedback information to the uplink Pcell and the uplink Scell carrier, the receiving end sends the corresponding uplink feedback information in the uplink Pcell and the uplink Scell carrier. The subframe is not aligned, and the receiving end does not need to perform uplink feedback information transmission in the uplink Pcell and the uplink Scell carrier at the same time, and the receiving end can send corresponding uplink feedback in the uplink Pcell and the uplink Scell carrier by using the handover mode. information. The range of time differences between unaligned subframes can be determined by verifying the time difference between the receiving end handovers. If the receiving end needs to send the uplink feedback information in the non-aligned subframes of the multiple uplink Scells, the receiving end sends the corresponding uplink feedback information in the uplink Scell.

When the subframes of the uplink feedback information sent by the receiving end in the uplink Pcell and the uplink Scell carrier are aligned, the receiving end sends the uplink feedback information corresponding to the downlink Pcell and the downlink Scell corresponding to the uplink Pcell and the uplink Scell respectively. The uplink feedback information, and the subframes in which the uplink Pcell and the uplink Scell send the uplink feedback information are time-aligned, and the receiving end needs to transmit the uplink feedback information on the uplink Pcell and the uplink Scell carrier at the same time.

The subframe in which the uplink information is sent by the receiving end in the uplink Pcell and the uplink Scell carrier is unaligned, and includes: the uplink feedback information subframe sent by the receiving end in the uplink Pcell and the uplink Scell is not time aligned, and the receiving end does not The uplink feedback information needs to be transmitted on both the uplink Pcell and the uplink Scell carrier. The uplink feedback information is transmitted through one or more of the following channels: PUCCH, PUSCH. For example, the uplink feedback information of the uplink Pcell and the uplink Scell of the receiving end is transmitted through the PUCCH or the PUSCH, or the uplink feedback information of the uplink Pcell and the uplink Scell of the receiving end is transmitted through the PUCCH and the PUSCH, respectively, or the uplink Pcell and the uplink of the receiving end. The uplink feedback information in the Scell is transmitted through the PUSCH and the PUCCH, respectively. The uplink feedback information may include uplink data of the receiving end. The transmission paths of the uplink feedback information sent by the receiving end in the uplink Pcell and the uplink Scell carrier may be the same or different. The transmission paths of the uplink feedback information sent by the receiving end in multiple uplink Scell carriers may be the same or different.

The type of the uplink feedback information may include one or more of the following: ACK/NACK, SR, CSI (including PMI, CQI, RI). For example, the uplink feedback information of the uplink Pcell and the uplink Scell of the receiving end are both ACK/NACK or SR or CSI, or the uplink feedback information of the uplink Pcell and the uplink Scell of the receiving end are ACK/NACK and CSI respectively; or the uplink Pcell of the receiving end The uplink feedback information in the uplink Scell and the uplink Scell are CSI and ACK/NACK, respectively. The types of uplink feedback information sent by the receiving end in the uplink Pcell and the uplink Scell carrier may be the same or different. The types of uplink feedback information sent by the receiving end in multiple uplink Scell carriers may be the same or different.

In addition, in the multi-carrier technology, if the type of the uplink feedback information that the receiving end needs to transmit simultaneously in the multiple uplink carriers is different, the receiving end may discard the uplink feedback information in the part of the uplink carrier, so that the receiving end is only in other The uplink feedback information that is not discarded is sent in the uplink carrier. For example: When the receiving end sends ACK/NACK and CSI information simultaneously in two uplink carriers (Carrier 1 and Carrier 2), the receiving end can discard (not transmit) the CSI of Carrier 2 and only transmit the ACK/NACK information of Carrier 1. In this case, the receiving end does not consider that the receiving end sends uplink feedback information in two or more uplink carriers at the same time.

There is no necessary relationship between the transmission path and the type of the uplink feedback information. The uplink feedback information transmission paths sent by the receiving end in the uplink Pcell and the uplink Scell carrier may be the same or different, and the types may be the same or different. When the receiving end sends the uplink feedback information in the uplink Pcell and the uplink Scell carrier through the uplink Pcell carrier, the receiving end may send the PUCCH format 3 in the uplink Pcell.

When the receiving end is configured with multiple uplink carriers, the receiving end may decide whether to switch the sending uplink according to whether the subframes that respectively send the uplink feedback information in multiple uplink carriers are aligned (equivalent to whether simultaneous transmission is needed in multiple uplink carriers). The uplink carrier of the feedback information. Further, the receiving end may have a detection failure. For example, the transmitting end, for example, the base station, schedules the data transmission of the receiving end in the two downlink carriers, but the receiving end only detects the data in one downlink carrier, and the other downlink. The data in the carrier is not detected by the receiving end. In this case, the receiving end considers that the transmitting end only schedules data in one downlink carrier, so that the receiving end only performs uplink feedback information transmission in the uplink carrier corresponding to the downlink carrier. However, the transmitting end receives the uplink feedback of the receiving end in the two uplink carriers corresponding to the two downlink carriers (the subframes corresponding to the uplink feedback information are not aligned) or the one uplink carrier (the subframe alignment corresponding to the uplink feedback information). information.

Obviously, since the receiving end does not detect the data of the transmitting end, the transmitting end and the receiving end think that the uplink carrier that sends the uplink feedback information is different. Two solutions are given for this situation,

A solution is as follows: The transmitting end needs to perform detection according to various possible situations. For example, the base station needs to detect whether there is uplink feedback information of the receiving end in each uplink carrier, or detect whether there are other uplink carriers in one of the uplink carriers. Upstream feedback information. Considering that the possibility of data loss at the receiving end is relatively small, the transmitting end can detect according to the established scheme that the receiving end does not lose data, and then detect according to another scheme, thereby reducing the complexity of the transmitting end; another solution is: The transmitting end indicates, by using signaling, which uplink carrier sends the uplink feedback information. The signaling here can be sent to the receiving end through the PDCCH or the ePDCCH, and the signaling can be simultaneously transmitted through multiple downlink carriers. After receiving the PDCCH or the ePDCCH in the downlink carrier, the receiving end parses the signaling, so as to obtain the corresponding sending uplink feedback. The uplink carrier of the information.

For different uplink feedback information, different strategies can also be adopted. For example, for the uplink feedback information that is not required to be sent according to the scheduling of the base station, for example, SR, CSI, the above two solutions may not be performed, but only the data information of the transmitting end needs to be received to determine whether uplink feedback information for the sending is needed. Perform the two solutions above.

On the base station side, when multiple carriers are configured for aggregation on the receiving end, the base station can process the uplink feedback information of the receiving end according to the following manner:

When the base station learns that the receiving end simultaneously sends the uplink feedback information in the uplink Pcell and the uplink Scell carrier, the base station receives the uplink feedback information in the uplink Pcell and the uplink Scell carrier only in the uplink Pcell carrier of the receiving end;

When the base station learns that the receiving end does not simultaneously send the uplink feedback information in the uplink Pcell and the uplink Scell carrier, the base station receives the uplink feedback information of the downlink Pcell or the downlink Scell in the uplink Pcell or the uplink Scell.

The base station can determine whether the receiving end sends the corresponding uplink feedback information and whether the subframe of the transmitted uplink carrier is aligned according to the downlink scheduling, so as to determine whether the receiving end sends the uplink feedback information in multiple uplink carriers at the same time. When the base station determines that the receiving end needs to simultaneously send the uplink feedback information in the uplink multiple Scells, the base station may receive the uplink feedback information of the multiple uplink Scells only in the uplink carrier with the smallest carrier index among the multiple uplink Scell carriers in the receiving end.

When the base station determines that the receiving end does not simultaneously send the uplink feedback information in multiple uplink carriers, the base station may separately receive the uplink feedback information from each uplink carrier.

The uplink feedback information is transmitted through one or more of the following channels: PUCCH, PUSCH. For example, the base station determines that the uplink feedback information in the uplink Pcell and the uplink Scell of the receiving end is transmitted through the PUCCH or the PUSCH, or the base station determines that the uplink feedback information in the uplink Pcell and the uplink Scell of the receiving end is transmitted through the PUCCH and the PUSCH, respectively, or the base station determines the uplink of the receiving end. The uplink feedback information in the Pcell and the uplink Scell is transmitted through the PUSCH and the PUCCH, respectively. The uplink feedback information may include uplink data (non-control type) at the receiving end. The base station may determine that the transmission path of the uplink feedback information sent by the receiving end in the uplink Pcell and the uplink Scell carrier is the same or different. The base station may also determine that the uplink feedback information transmission path sent by the receiving end in multiple uplink Scell carriers is the same or different.

The type of the uplink feedback information may include one or more of the following: ACK/NACK, SR, CSK including PMI, CQK RI). For example, the base station determines that the uplink feedback information in the uplink Pcell and the uplink Scell of the receiving end is ACK/NACK or SR or CSI, or the base station determines that the uplink feedback information in the uplink Pcell and the uplink Scell of the receiving end are ACK/NACK and CSI, respectively; The base station determines that the uplink feedback information in the uplink Pcell and the uplink Scell of the receiving end are CSI, ACK/NACK, and the like, respectively. The base station may determine that the types of uplink feedback information sent by the receiving end in the uplink Pcell and the uplink Scell carrier are the same or different. The base station may also determine that the types of uplink feedback information sent by the receiving end in multiple uplink Scell carriers are the same or different. In addition, in the multi-carrier technology, if the type of the uplink feedback information that the receiving end needs to transmit simultaneously in the multiple uplink carriers is different, the receiving end may discard the uplink feedback information in the part of the uplink carrier, so that the receiving end is only in other The uplink feedback information that is not discarded is sent in the uplink carrier. For example, when the base station can determine that the receiving end simultaneously sends ACK/NACK and CSI information in two uplink carriers (Carrier 1 and Carrier 2), the receiving end discards the CSI of Carrier 2 and transmits only the ACK/NACK information of Carrier 1. In the case, the base station does not consider that the receiving end simultaneously sends uplink feedback information in two or more uplink carriers.

There is no necessary relationship between the transmission path and the type of the uplink feedback information. The base station may determine that the uplink feedback information transmission paths sent by the receiving end in the uplink Pcell and the uplink Scell carrier are the same or different, and the types may be the same or different.

The base station determines that the receiving end sends the uplink feedback information in the uplink Pcell and the uplink Scell carrier through the uplink Pcell carrier, and the base station determines that the receiving end sends the PUCCH format 3 in the uplink Pcell. When the base station determines that the receiving end is configured with multiple uplink carriers, the base station may determine whether the subframes of the uplink feedback information respectively sent by the receiving end in the multiple uplink carriers are aligned (equivalent to whether simultaneous transmission is required in multiple uplink carriers). Whether to switch the uplink carrier that sends the uplink feedback information. Further, the receiving end may have a detection failure. For example, the transmitting end (for example, the base station) schedules the data transmission of the receiving end in the two downlink carriers, but the receiving end only detects the data in one downlink carrier, and the other downlink. The data in the carrier is not detected by the receiving end. In this case, the receiving end considers that the transmitting end only schedules data in one downlink carrier, so that the receiving end only performs uplink feedback information transmission in the uplink carrier corresponding to the downlink carrier. However, the transmitting end receives the uplink feedback of the receiving end in the two uplink carriers corresponding to the two downlink carriers (the subframes corresponding to the uplink feedback information are not aligned) or the one uplink carrier (the subframe alignment corresponding to the uplink feedback information). information.

Obviously, since the receiving end does not detect the data of the transmitting end, the transmitting end and the receiving end think that the uplink carrier that sends the uplink feedback information is different. Two solutions are provided for this situation. One solution is that the base station needs to perform detection according to various possible conditions. For example, the base station needs to detect whether there is uplink feedback information of the receiving end in each uplink carrier, or one of them. The uplink carrier detects whether there is uplink feedback information of other uplink carriers. Considering that the possibility of data loss at the receiving end is relatively small, the base station can perform detection according to a predetermined scheme in which the receiving end does not lose data, and then detect according to another scheme, thereby reducing the complexity of the transmitting end. Another solution is that the base station indicates by signaling on which uplink carrier the uplink feedback information is sent by the receiving end. The signaling here can be sent to the receiving end through the PDCCH or the ePDCCH, and the signaling can be simultaneously transmitted through multiple downlink carriers. After receiving the PDCCH or the ePDCCH in the downlink carrier, the receiving end parses the signaling, so as to obtain the corresponding uplink carrier that sends the uplink feedback information.

For different uplink feedback information, different strategies can also be adopted. For example, for uplink feedback information that does not need to be determined according to base station scheduling, such as SR, CSI, the base station needs Perform the two solutions above.

When multiple carriers are configured for aggregation on the receiving end, the base station may allocate resources for uplink feedback information to the receiving end in the following manner:

When the base station learns that the receiving end does not simultaneously send the uplink feedback information in the uplink Pcell and the uplink Scell carrier, the base station allocates resources for the uplink Pcell of the receiving end or the uplink feedback information of the downlink Scell in the uplink Pcell or the uplink Scell.

When the base station determines that the receiving end needs to simultaneously send the uplink feedback information in the uplink multiple Scells, the base station may allocate the resources of the uplink feedback information only in the uplink carriers with the smallest carrier index among the multiple uplink Scell carriers at the receiving end.

When the base station determines that the receiving end does not simultaneously send the uplink feedback information in the multiple uplink carriers, the base station may allocate the resources of the uplink feedback information to the respective uplink carriers.

The uplink feedback information is transmitted through one or more of the following channels: PUCCH, PUSCH. For example, the base station determines that the uplink feedback information in the uplink Pcell and the uplink Scell of the receiving end is transmitted through the PUCCH or the PUSCH, or the base station determines that the uplink feedback information in the uplink Pcell and the uplink Scell of the receiving end is transmitted through the PUCCH and the PUSCH, respectively, or the base station determines the uplink of the receiving end. The uplink feedback information in the Pcell and the uplink Scell is transmitted through the PUSCH and the PUCCH, respectively. The uplink feedback information may include uplink data (non-control type) at the receiving end. The base station may determine that the transmission path of the uplink feedback information sent by the receiving end in the uplink Pcell and the uplink Scell carrier is the same or different. The base station may also determine that the uplink feedback information transmission paths sent by the receiving end in multiple uplink Scell carriers are the same or different.

The type of the uplink feedback information may include one or more of the following: ACK/NACK, SR, CSI (including PMI, CQL RI). For example, the base station determines the uplink Pcell and the uplink Scell of the receiving end. The uplink feedback information in the uplink is ACK/NACK or SR or CSI, or the base station determines that the uplink feedback information in the uplink Pcell and the uplink Scell of the receiving end is ACK/NACK and CSI, respectively; or the base station determines the uplink Pcell and the uplink Scell in the receiving end. The uplink feedback information is CSI and ACK/NACK, and so on. The base station may determine that the types of uplink feedback information sent by the receiving end in the uplink Pcell and the uplink Scell carrier are the same or different. The base station may also determine that the types of uplink feedback information sent by the receiving end in multiple uplink Scell carriers are the same or different. In addition, in the multi-carrier technology, if the type of the uplink feedback information that the receiving end needs to transmit simultaneously in the multiple uplink carriers is different, the receiving end may discard the uplink feedback information in the part of the uplink carrier, so that the receiving end is only in other The uplink feedback information that is not discarded is sent in the uplink carrier. For example, when the base station can determine that the receiving end simultaneously transmits ACK/NACK and CSI information in two uplink carriers (Carrier 1 and Carrier 2), the receiving end discards the CSI of Carrier 2, and only sends ACK/NACK information in Carrier 1. In this case, the base station does not consider that the receiving end sends uplink feedback information in two or more uplink carriers at the same time.

When the base station determines that the uplink information of the uplink Pcell and the uplink Scell carrier is transmitted by the receiving end through the uplink Pcell carrier, the base station may allocate resources in the uplink Pcell according to the PUCCH format 3.

When the base station determines that the receiving end is configured with multiple uplink carriers, the base station may determine whether the subframes of the uplink feedback information respectively sent by the receiving end in the multiple uplink carriers are aligned (equivalent to whether simultaneous transmission is required in multiple uplink carriers). Whether to switch the uplink carrier that sends the uplink feedback information. Further, the receiving end may have a detection failure. For example, the transmitting end (for example, the base station) schedules the data transmission of the receiving end in the two downlink carriers, but the receiving end only detects the data in one downlink carrier, and the other downlink. The data in the carrier is not detected by the receiving end. The receiving end considers that the transmitting end only schedules data in one downlink carrier, so that the receiving end only performs uplink feedback information transmission in the uplink carrier corresponding to the downlink carrier, but the transmitting end corresponds to 2 downlink carriers. The uplink feedback information of the receiving end is received in the uplink carrier (the subframe corresponding to the uplink feedback information is not aligned) or the uplink carrier (the subframe alignment corresponding to the uplink feedback information).

Obviously, since the receiving end does not detect the data of the transmitting end, the transmitting end and the receiving end think that the uplink carrier that sends the uplink feedback information is different. A solution is provided for this situation, and the base station indicates by signaling, in which uplink carrier the receiving end allocates resources for transmitting uplink feedback information. The signaling here can be sent to the receiving end through the PDCCH or the ePDCCH, and the signaling can be simultaneously transmitted through multiple downlink carriers. After receiving the PDCCH or ePDCCH in the downlink carrier, the receiving end parses the signaling, so as to obtain the corresponding uplink carrier and resource for sending the uplink feedback information.

For different uplink feedback information, different strategies can also be adopted. For example: For uplink feedback information, such as SR, CSI, that does not need to be determined according to base station scheduling, the base station needs to perform one of the above solutions.

Preferably, when the base station learns that the receiving end sends the uplink feedback information in the uplink Pcell and the uplink Scell carrier, the base station may also delete the resource used by the receiving end to send the uplink feedback information in the uplink Scell.

The above method is particularly suitable for the following situations: The receiving end is configured as TDD, FDD carrier aggregation, the Pcell of the receiving end is configured as TDD, and the receiving end does not have the capability of transmitting in multiple uplink carriers at the same time.

For the case where the uplink feedback information is ACK/NACK, the base station may configure the TDD carrier as the Pcell of the receiving end, and the FDD carrier as the Scell of the receiving end, and the base station sends the data to the receiving end by using the downlink Pcell and the downlink Scell respectively. After receiving the scheduling signaling and data, the receiving end determines the uplink feedback ACK/NACK corresponding to the downlink Pcell and the downlink Scell. Whether the information is transmitted at the same time. If yes, the receiving end only sends the ACK/NACK corresponding to the downlink Pcell and the downlink Scell in the resources allocated in the uplink Pcell; preferably, the PUCCH format 3 is used for sending. If not, the receiving end sends the current ACK/NACK in the uplink Pcell and the uplink Scell, respectively.

When the base station sends data to the receiving end through the downlink Pcell and the downlink Scell scheduling, the base station can determine the feedback time point (ie, the subframe) of the receiving end in the uplink Pcell and the uplink Scell according to the agreed ACK/NACK feedback rule, so that the base station can learn Whether the subframes of the ACK/NACK are aligned are aligned. If aligned, the base station allocates resources for the transmission of the current ACK/NACK of the receiving end in the uplink Pcell, and performs subsequent reception. If there is no alignment, the base station is respectively in the uplink Pcell and The uplink Scell allocates resources for the ACK/NACK transmission of the receiving end, and performs subsequent reception.

In the case that the uplink feedback information is ACK/NACK, the base station may determine that the receiving end is in the uplink Pcell and the uplink Scell according to the agreed ACK/NACK feedback rule when the downlink Pcell and the downlink Scell send the scheduling signaling to the receiving end scheduling data. The feedback time point (ie, the subframe), so as to know whether the subframes of the feedback ACK/NACK are aligned (whether the receiving end needs to be transmitted in multiple uplink carriers at the same time).

If aligned, the base station adds a parameter A for indicating the ACK/NACK corresponding to the current downlink Pcell and the downlink Scell in which the carrier is transmitted in the scheduling signaling (transmitted through the PDCCH or the ePDCCH) (the PDCCH or the ePDCCH may also be used. The existing parameter indicates the parameter A, or the idle state of the existing parameter is used to represent the parameter A). After receiving the scheduling signaling, the receiving end obtains the parameter A from it, so as to know which carrier to send the corresponding ACK/NACK. . Correspondingly, the base station also allocates resources for the ACK/NACK for this transmission and performs subsequent reception only in the carrier indicated by parameter A. Preferably, the receiving end transmits using PUCCH format 3.

If there is no alignment, the base station may not use the parameter A in the scheduling signaling (preferably, the parameter A is not used, and the parameter 8 may be used in the actual application, and the processing method when using the parameter A is The foregoing manner is the same.) The receiving end sends an ACK/NACK in the uplink Pcell and the uplink Scell, respectively. Correspondingly, the base station allocates resources for the ACK/NACK for the current transmission in the uplink Pcell and the uplink Scell, and performs subsequent reception.

The above case where the uplink feedback information is ACK/NACK and the case where the uplink feedback information is ACK/NACK is similarly applied to the case where the uplink carrier is a plurality of Scells.
