Abstract:
1. A transmitting apparatus that transmits pilot signals to a plurality of user equipment, the transmitting apparatus comprising: a generator configured to generate a signal including pattern information indicating which pilot pattern among at least two pilot patterns is respectively assigned to each time slot of a plurality of time slots, each of the pilot patterns representing different densities of pilot signals arranged in mutually different patterns in at least one of the frequency domain and the time domain, the different densities of pilot signals corresponding to different proportions of pilot symbols, at least two of the time slots being assigned different pilot patterns from among the at least two pilot patterns; and a transmitter configured to broadcast the signal including the pattern information indicating which pilot pattern among the at least two pilot patterns is respectively assigned to each time slot of the plurality of time slots to the plurality of user equipment, and to transmit the pilot signals according to the pattern information indicating which pilot pattern among the at least two pilot patterns is respectively assigned to each of the plurality of time slots.
