Abstract: A first method comprises sending to at least one user equipment a signal, the signal including hopping parameters and being related to sounding reference signal (SRS) transmission, wherein at least one subset/SRS resource is sent for at least one numerology/beam pair, and wherein independent hopping is carried out in each subset for one specific numerology/beam pair or, when different SRS resources are configured for different numerologies/beams, the subset is defined for each SRS resource and independent hopping is made for each SRS resource; and receiving an SRS transmission from the at least one user equipment in accordance with the signal.

Abstract: The present invention relates to an apparatus and method for transmitting channel state information in a wireless communication system. This specification discloses a UE including: a reception unit for receiving coordination mode activation information indicating an ICIC mode to restrict a measurement of a channel state, and receiving CSI request information requesting aperiodic transmission of the CSI, a UE configuration control unit for switching a state of the UE to the ICIC mode based on the coordination mode activation information and for configuring one or more serving cells in the UE, a measurement unit for measuring a channel state for a subset in an activated serving cell from among the configured one or more serving cells based on the CSI request information, an information generation unit for generating CSI regarding the measured channel state, and a transmission unit for transmitting the generated CSI to the BS.

Abstract: A space-time coding apparatus receives two groups of inputs and outputs two groups of outputs. A configuration of each output group is based on spatial diversity and a configuration between the groups of outputs is based on spatial multiplexing. The space-time coding apparatus may include two spatial diversity coders whose outputs are each connected two spatial multiplexing coders. A plurality of antennas may be respectively connected to outputs of each spatial multiplexing coder. Coding coefficients are configured so that a first wireless receiving terminal corresponding to a first group of outputs receives only input signal components of a first group of inputs, and a second wireless receiving terminal corresponding to a second group of outputs receives only input signal components of a second group of inputs.
