individual Resource Unit (Resource Element is called for short RE), wherein N
symbrepresent the number of the OFDM symbol in 1 slot,
represent the number of Resource Block continuous subcarrier in frequency domain.RB is mapped in and on physical resource, is called Physical Resource Block (Physical Resource Block is called for short PRB).
(the Physical Uplink Control Channel of PUCCH in LTE system at present, Physical Uplink Control Channel) for loading ACK/NACK(Acknowledgement/NegativeAcknowledgement, confirmed/non-confirmed information), CQI(Channel Quality Indicator, channel quality instruction), SRI(Scheduling Requirement Indicator, dispatch request instruction) etc. information.The PUCCH of different-format, comprises for sending: SRI, uplink ACK/NACK, CQI feedback, or the different ascending control information such as CQI feedback+ACK/NACK, and as shown in the table, PUCCH has different-format as shown in the table:

11. devices as claimed in claim 10, is characterized in that,
Described resource multiplex unit is by the Physical Uplink Control Channel of repeated link with direct transfer the multiplexing physical uplink control channel of link in same resource block time, same Resource Block is distributed to repeated link and the link that direct transfers simultaneously, on this Resource Block, the Physical Uplink Control Channel multiplexing via node of difference of the Physical Uplink Control Channel of repeated link and the link that direct transfers and the ascending control information of terminal.
12. devices as claimed in claim 11, is characterized in that,
Described resource multiplex unit is by the Physical Uplink Control Channel of repeated link with direct transfer the multiplexing physical uplink control channel of link in same resource block time, and its multiplex mode is resource multiplexing or resource hybrid multiplex completely;
Wherein, all orthogonal sequence resources, cyclic shift resource or orthogonal sequence resource and the cyclic shift resource of Resource Block described in the completely multiplexing multiplexing physical uplink control channel that refers to the Physical Uplink Control Channel of repeated link and the link that direct transfers of described resource; Described resource hybrid multiplex refers to part orthogonal sequence resource, cyclic shift resource or orthogonal sequence resource and the cyclic shift resource of Resource Block described in the Physical Uplink Control Channel of repeated link and the multiplexing physical uplink control channel of link of direct transferring.
13. devices as described in claim 11 or 12, is characterized in that,
Described resource multiplex unit, by the Physical Uplink Control Channel of repeated link with direct transfer the multiplexing physical uplink control channel of link on different resource piece time, is respectively the repeated link Resource Block different with the link assignment that direct transfers;
Wherein, on the Resource Block of distributing to repeated link, the Physical Uplink Control Channel of repeated link is the ascending control information of multiplexing via node only; Distributing on the Resource Block of the link that direct transfers, the Physical Uplink Control Channel of the link that direct transfers is the ascending control information of multiplex terminal only.
