Transmitting uplink control information over a data channel or over a control channel

摘要

Methods and apparatus are described for User Equipment (UE) to concurrently transmit Uplink Control Information (UCI) and data information to a Node B. The Node B can configure the UE to transmit UCI together with data information in a Physical Uplink Shared CHannel (PUSCH) or separate from data information in a Physical Uplink Control CHannel (PUCCH). The UE may also determine whether to transmit UCI together with data information in the PUSCH or separate from data information in the PUCCH based on criteria involving a ratio of PUSCH resources for UCI transmission over the total PUSCH resources, a Modulation and Coding Scheme (MCS) for the data information, an absolute power difference between PUCCH and PUSCH transmissions, whether the PUSCH transmission uses frequency hopping, and/or whether spatial multiplexing is used for the data transmission.

1. A method for User Equipment (UE) to transmit Uplink Control Information (UCI) to a Node B in a communication system, comprising:
determining, through Radio Resource Control (RRC) signaling, configuration information indicating simultaneous Physical Uplink Shared CHannel (PUSCH) and Physical Uplink Control CHannel (PUCCH) transmission; receiving downlink data; generating the UCI comprising at least one of a Hybrid Automatic Repeat reQuest-ACKnowledgement (HARQ-ACK) and a Channel Quality Indicator (CQI) to be transmitted in a subframe; determining whether a PUSCH is transmitted in the subframe; and transmitting the UCI on at least one of the PUSCH and a PUCCH based on at least one of the configuration information indicating simultaneous PUSCH and PUCCH transmission and the determination whether the PUSCH is transmitted in the subframe.
