Abstract:
The present disclosure relates to a method of providing a pre-5th-Generation (5G) or 5G communication system for supporting higher data rates Beyond 4th-Generation (4G) communication system, such as Long Term Evolution (LTE). The method includes receiving configuration information comprising at least one information element indicating transmission resources for the reference signals, receiving downlink control information indicating that a transmission of at least one of the reference signals is activated, and receiving the at least one of the reference signals based on the configuration information, in response to receiving the downlink control information.
Abstract:
A method and apparatus are described for a User Equipment (UE) to transmit in a control channel ACKnowledgement signals associated with a Hybrid Automatic Repeat reQuest process (HARQ-ACK signals) in response to receiving Transport Blocks (TBs) transmitted from a base station. The UE conveys the HARQ-ACK information by selecting one resource from multiple resources in the control channel and by selecting a constellation point of the modulation scheme for the HARQ-ACK signal. Transmission diversity is supported using different control channel resources that are already available to the UE without configuring additional resources. Design principles are described to optimally map the HARQ-ACK information to control channel resources and modulation constellation points for a Time Division Duplex (TDD) system and for a Frequency Division Duplex (FDD) system.
