DETAILED DESCRIPTION

Section headings are used in the present document only for ease of understanding and do not limit scope of the embodiments to the section in which they are described. Furthermore, while embodiments are described with reference to 5G examples, the disclosed techniques may be applied to wireless systems that use protocols other than 5G or 3GPP protocols.

The development of the new generation of wireless communication –5G New Radio (NR) communication –is a part of a continuous mobile broadband evolution process to meet the requirements of increasing network demand. NR will provide greater throughput to allow more users connected at the same time. Other aspects, such as energy consumption, device cost, spectral efficiency, and latency are also important to meeting the needs of various communication scenarios.

In the current technology, if carrier aggregation is used for a user equipment (UE) , a hybrid automatic repeat request acknowledgement (HARQ-ACK) physical uplink control channel (PUCCH) may always be transmitted in the uplink primary carrier (Pcell) . Accordingly, the UE using the current technology may be unable to dynamically trigger a carrier for the control channel.

FIG. 1 is an example block diagram 100 illustrating multiple transmission carriers. However, in some cases, for example, as shown in Figure 1, CC0 and CC1 are aggregated, where CC0 is the primary carrier and CC1 is the secondary carrier. The slot configurations of CC0 and CC1 are shown in Figure 1, where D indicates downlink slot, S indicates flexible slot and U indicates uplink slot. When the PDSCH in the first downlink slot of the CC0 is scheduled and required to feed back HARQ-ACK in the third slot, but the third slot is a DL slot in the CC0, HARQ-ACK PUCCH may be unable to be transmitted. However, the transmission of the URLLC service may not be delayed.

Therefore, the HARQ-ACK PUCCH can be switched to the CC1 for transmission, because the HARQ-ACK PUCCH corresponds to a UL slot in the CC1. This method can also be used with other PUCCHs, such as CSI PUCCH and SR PUCCH.

Example Embodiment 1

The gNodeB and the UE can agree to use the following rules to trigger the UE to dynamically switch/hand over the PUCCH transmission carrier.

A PUCCH transmission can be configured or is in the first carrier by default (existing, PUCCH is in the UL Pcell by default) . The first carrier and the second carrier can be associated through the configuration signaling, and the switch/handover of the PUCCH transmission carrier is allowed between them. The PUCCH resources determined by the UE from the first carrier based on the PUCCH indication information in the DCI in the PDCCH may be invalid. Then, the UE can determine to switch/hand over the PUCCH transmission carrier to the second carrier. The PUCCH indication information may be automatically applicable to the second carrier to determine an valid PUCCH resource. For example, PUCCH related parameters such as k1(PDSCH-to-HARQ_feedback timing indicator) , PRI (PUCCH resource indicator) , TPC (TPC command for scheduled PUCCH) and SCS (Subcarrier spacing) can be executed according to the configuration of the second carrier.

Here, the PUCCH can include any of HARQ-ACK PUCCH, SR PUCCH, CSI PUCCH, NACK only PUCCH, ACK only PUCCH and BFR PUCCH.

PUCCH resources can be valid. If PUCCH resources are valid, it can indicate that one PUCCH resource is located in available uplink symbols and has available frequency domain resources. Otherwise, the PUCCH resource is invalid. For example, if a PUCCH resource determined based on the PUCCH indication information in the first carrier is overlapped with one DL slot, the PUCCH resource is invalid. The valid PUCCH resources may also be the following cases: The resources corresponding to the determined PUCCH resources are uplink resources, or the resources corresponding to the determined PUCCH resources are uplink resources and are allowed to transmit PUCCH resources, or the resources corresponding to the determined PUCCH resources do not overlap with the downlink resources, or the resources corresponding to the determined PUCCH resources are within the bandwidth range of the carrier.

PUCCH indication information can include at least one of the following: PDSCH-to-HARQ_feedback timing indicator (that is, k1) : Indicating the position of the slot where the PUCCH is located, PUCCH resource indicator (that is, PRI) : Indicating a PUCCH resource from the PUCCH resource set, Subcarrier spacing (that is, SCS) : Indicating a subcarrier spacing of the carrier where the PUCCH is located, and/or TPC command for scheduled PUCCH (that is, TPC) : Indicating a power control information for PUCCH transmission.

If there are multiple second carriers, the UE may select one as the second carrier. If the second carrier is multiple carriers, the UE may use at least one of the following rules to attempt to determine a PUCCH resource from each second carrier until the first valid PUCCH resource is determined in accordance with the PUCCH indication information. The second carrier where the first valid PUCCH resource is located is also used as a PUCCH transmission carrier.

The rules can include any of: A rule, attempting to determine a first valid PUCCH resource according to the secondary cell index (or Serving Cell Index) of the second carrier in ascending or descending; Or B rule, attempting to determine a first valid PUCCH resource according to the frequency points of the second carrier in ascending or descending.

The rules can include one of: attempting to determine a earliest and valid PUCCH resource from the second carriers. If several same earliest and valid PUCCH resources are determined from several carriers from the second carriers, the A or B rule can be used for determining a final PUCCH resource from the several carriers.

gNodeB can configure the first carrier and the second carrier to be associated in order to switch the PUCCH transmission carrier through the RRC signaling/MAC CE for UE. The first carrier can include a UL Pcell, and the second carrier can include a UL Scell.

In order to achieve low UE cost, a new signaling 1 can also be introduced to notify the gNodeB that the UE has/or does not have the capability to support the switch/handover of the carrier of PUCCH transmission. For example, new signaling 1 notifies gNodeB: The UE can be capable of supporting the switch/handover of the carrier of PUCCH transmission. If the gNodeB receives this new signaling 1, it can instruct the UE to switch the PUCCH transmission carrier. Otherwise, it cannot instruct the UE to switch the carrier of PUCCH transmission (meaning that the PUCCH is transmitted in Pcell) . As another example, the new signaling 1 notifies gNodeB that the UE is not capable of supporting the switch/handover of the PUCCH transmission carrier. If the gNodeB receives this new signaling 1, it may be unable to instruct the UE to switch the carrier of PUCCH transmission. Otherwise, it can instruct the UE to switch the carrier of PUCCH transmission.

In order to reduce the complexity of gNodeB scheduling, a new signaling 2 can be introduced to notify the UE that the gNodeB allows (or does not allow) the UE to switch the carrier of PUCCH transmission. The new signaling 2 can be configured to the UE by gNodeB via RRC or MAC CE signaling.

If multiple carriers are configured for a UE to switch the PUCCH transmission between these carriers, the bit size of PUCCH-related parameter fields (such as k1, PRI, TPC) in the DCI can be determined based on the configuration of one carrier being from the multiple carriers and resulting in a largest bit size.

According to the method described in Embodiment 1, the parameter fields in DCI may not need to be modified.

Example Embodiment 2

In embodiment 1, there may be always one PUCCH transmission carrier by default. After the predefined conditions are met, the PUCCH transmission carrier may be handed over to another carrier. In embodiment 2, embodiment 1 is further extended. For example, a default PUCCH transmission carrier is not needed, and a PUCCH transmission carrier is always dynamically determined from multiple carriers associated to switch PUCCH transmission carrier in accordance with the predefined rules.

The gNodeB and the UE can agree to determine a PUCCH transmission carrier in accordance with the following predefined rules. For UE, multiple carriers are configured to allow determining a PUCCH transmission carrier between them. The gNodeB can send PUCCH indication information. In accordance with the PUCCH indication information and one of the following predefined rules, the UE can attempt to determine a PUCCH resource from multiple carriers until the first valid PUCCH resource is determined. The carrier where the first valid PUCCH resource is located is used to transmit the PUCCH.

The predefined rules can include any of: C rule, attempts to determine a first valid PUCCH resource according to Serving Cell Index of the multiple carriers in ascending or descending; Or D rule, attempts to determine a first valid PUCCH resource according to the frequency points of the multiple carriers in ascending or descending.

The rules can include of: attempting to determine a earliest and valid PUCCH resource from the multiple carriers. If several same earliest and valid PUCCH resources are determined from several carriers from the multiple carriers, the C or D rule can be used for determining a final PUCCH resource from the several carriers.

Here, PUCCH includes any of HARQ-ACK PUCCH, SR PUCCH, CSI PUCCH, NACK only PUCCH, ACK only PUCCH and BFR PUCCH.

If PUCCH resources are valid, it can indicate that one PUCCH resource is located in available uplink symbols and has available frequency domain resources. Otherwise, the PUCCH resource is invalid. For example, if a PUCCH resource determined based on the PUCCH indication information in the first carrier is overlapped with one DL slot, the PUCCH resource is invalid. The valid PUCCH resource may also be the following cases: The resources corresponding to the determined PUCCH resources can be uplink resources, or the resources corresponding to the determined PUCCH resources are uplink resources and are allowed to transmit PUCCH resources, or the resources corresponding to the determined PUCCH resources do not overlap with the downlink resources, or the resources corresponding to the determined PUCCH resources are within the bandwidth range of the carrier.

PUCCH indication information can include at least one of the following: PDSCH-to-HARQ_feedback timing indicator (that is, k1) : Indicating the position of the slot where the PUCCH is located; PUCCH resource indicator (that is, PRI) : Indicating a PUCCH resource from the PUCCH resource set; Subcarrier spacing (that is, SCS) : Indicating a subcarrier spacing of the carrier where the PUCCH is located; and/or TPC command for scheduled PUCCH (that is, TPC) : Indicating a power control information for PUCCH transmission.

In order to achieve low UE cost, a new signaling 1 can also be introduced to notify the gNodeB that the UE has/or does not have the capability to support the switch/handover of the carrier of PUCCH transmission. For example, new signaling 1 notifies gNodeB: The UE is capable of supporting the switch/handover of the carrier of PUCCH transmission. If the gNodeB receives this new signaling 1, it can instruct the UE to switch the carrier of PUCCH transmission. Otherwise, it cannot instruct the UE to switch the carrier of PUCCH transmission (meaning that the PUCCH is transmitted in Pcell) . As another example, the new signaling 1 notifies gNodeB that the UE is not capable of supporting the switch/handover of the carrier of PUCCH transmission. If the gNodeB receives this new signaling 1, it cannot instruct the UE to switch the carrier of PUCCH transmission. Otherwise, it can instruct the UE to switch the carrier of PUCCH transmission.

If multiple carriers are configured for a UE to switch the PUCCH transmission between these carriers, the bit size of PUCCH-related parameter fields (such as k1, PRI, TPC) in the DCI can be determined based on the configuration of one carrier being from the multiple carriers and resulting in a largest bit size

The advantage of embodiment 2 is that it can avoid signaling to indicate PUCCH transmission carriers. It can also be compatible with the existing mechanisms, for example, the methods of transmitting PUCCHs on PCells can be compatible.

The method of any of claims 15 and 17, wherein the PUCCH indication information includes any of: a physical downlink shared channel (PDSCH) to HARQ feedback (PDSCH-to-HARQ_feedback) timing indicator, a PUCCH resource indicator (PRI) , a subcarrier spacing (SCS) , and a transmit power control (TPC) command for a scheduled PUCCH.
The method of claim 15, wherein the predefined rule includes determining a valid PUCCH resource according to a secondary cell index or serving cell index of the first transmission resource and/or the second transmission resource in any of an ascending or descending order, wherein a valid PUCCH resource includes that the PUCCH resource is located in available uplink symbols and/or frequency domain resources.
The method of claim 15, wherein the predefined rule includes determining a valid PUCCH resource according to a frequency points of the first transmission resource and/or the second transmission resource in any of an ascending or descending order, wherein a valid PUCCH resource includes that the PUCCH resource is located in available uplink symbols and/or frequency domain resources.
The method of claim 15, wherein the predefined rule includes determining a PUCCH resource from the first transmission resource and/or the second transmission resource based on which PUCCH resource is valid and transmitted earliest, wherein a valid PUCCH resource includes that the PUCCH resource is located in available uplink symbols and/or frequency domain resources.
The method of claim 15, further comprising:

transmitting, by the network node, a first signaling message to the terminal indicating whether to switch from the first transmission resource to the second transmission resource.
The method of claim 15, wherein the terminal is configured to attempt to determine a PUCCH resource from the first transmission resource and the second transmission resource until a first valid PUCCH resource is determined, wherein the control information is transmitted on a carrier associated with the first valid PUCCH resource or the earliest valid PUCCH resource.
An apparatus for wireless communication comprising a processor that is configured to carry out the method of any of claims 1 to 25.
A non-transitory computer readable medium having code stored thereon, the code when executed by a processor, causing the processor to implement a method recited in any of claims 1 to 25.
