Problems solved by technology

Those skilled in the art will easily understand that if the PUCCH resource allocation method on the SCell still adopts the PUCCH resource allocation method on the PCell, the position information indicating resource allocation will be confused, so that the reliable transmission of uplink control data cannot be realized

Embodiment approach 1

[0085] In Embodiment 1, in the FDD mode, when the downlink control channel and the uplink control channel are respectively located on paired component carriers, and formats 1a and 1b of the uplink control channel or format 1b with channel selection are used , for multiple DL resource sets including only SCC, allocating resources to the uplink control channel includes:

[0086] Determine the said The location of the resources of the uplink control channel, so as to allocate resources to the uplink control channel.

[0087] Specifically, there are two situations as follows.

[0088] Scenario 1

[0089] The position of the PDSCH and PUCCH resources obtained by detecting the PDCCH on the YCC (corresponding to format 1a or 1b) or (corresponding to format 1b with channel selection) can be based on the first control channel element used to transmit the corresponding PDCCH to be calculated.

[0090] Scenario 2

[0091] The position of the PDSCH and PUCCH resources obtain...

Embodiment approach 2

[0093] In Embodiment 2, in the FDD mode, when the downlink control channel and the uplink control channel are respectively located on paired component carriers, and formats 1a and 1b of the uplink control channel or format 1b with channel selection are used , for multiple DL resource sets including only SCC, allocating resources to the uplink control channel includes:

[0094] According to the index in the first control channel element CCE of the downlink control information element in the first downlink control channel, the index in the first enhanced control channel element ECCE, the information in the HARQ-ACK resource offset field, and the information in other downlink control channels at least one of the information in the TPC field of the TPC domain and the resource list configured by the upper layer to determine the location of the resources of the uplink control channel, so as to allocate resources to the uplink control channel.

[0095] Based on the fact that multiple...

Embodiment approach 3

[0103] In Embodiment 3, in the FDD mode, the downlink control channel is located in a downlink SCC other than the SCC where the uplink control channel is located, and formats 1a and 1b of the uplink control channel or format 1b with channel selection are used When , for multiple DL resource sets including only SCC, allocating resources to the uplink control channel includes:

[0104] According to the information in the TPC domain in the downlink control channel and the resource list configured by the high layer, determine the location of the resources of the uplink control channel, so as to allocate resources to the uplink control channel.

[0105] Specifically, for the PDSCH obtained by detecting the PDCCH or EPDCCH on the SCC except the YCC in the detection set, the resource list (for example, including four resource value) to determine the position of the PUCCH resource

Abstract

Embodiments of the present disclosure provide a method and device for resource allocation of an uplink control channel. In one embodiment according to the present disclosure, the method divides downlink DL subframes on all carriers used for carrier aggregation into multiple DL resource sets; for each DL resource in the multiple DL resource sets set, configure an uplink control channel; and allocate resources to the uplink control channel for multiple DL resource sets including only the secondary component carrier SCC. According to the embodiments of the present disclosure, the transmission of the uplink control channel can be realized in the carrier aggregation scenario containing multiple SCells in the LTE-A system, and the complexity of HARQ timing and scheduling can be simplified.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of wireless communication, and more specifically relate to resource allocation of an uplink control channel for carrier aggregation. Background technique [0002] The mobile communication Long Term Evolution (LTE) system formulated by the Third Generation Partnership Project (3GPP) organization can support high-speed data and media transmission and high-capacity voice communication. In order to provide a higher data rate on this basis and support more user services and new service types, the 3GPP organization is actively promoting the formulation of related standards called LTE-Advanced (LTE-A) systems. Among them, in LTE-A release 10, the concept of carrier aggregation is further introduced to support wider bandwidth, which allows two or more component carriers to be aggregated together to support LTE-A transmission bandwidth greater than 20MHz. For example, an LTE-A system can suppo...
