FIELD: information technologies. ^ SUBSTANCE: single-address reference symbols are multiplexed with transfers in a single-frequency network, which use duration of a longer cyclic prefix. Single-address reference symbols are sent in the first symbol of a slot, containing both a single-address transfer and a transfer in a single-frequency network. Frequency used for single-address reference symbols alternates between the first symbol and the next symbol in a subframe. ^ EFFECT: provision of feedback in a common frequency range. ^ 46 cl, 15 dwg |
