Method and apparatus for concerted signal transmission on multiple antennas
First Claim
1. A communication method for use in a network in which a plurality of user terminals are allocated respective symbol positions within timeslots for communication to at least one of the plurality of user terminals from a base station, comprising:
- periodically transmitting, from the base station, a signal representing coded information to the at least one of the plurality of user terminals utilizing at least two antennas belonging to the base station, the signal being transmitted within each of a plurality of periodic timeslots, the plurality of periodic timeslots being determined based on at least a mobility of the plurality of user terminals, each of the at least two antennas transmitting same coded information only during a symbol position assigned to each of the at least two antennas, the assigned symbol positions being separated in time according to a specified sequential spacing of symbol positions within the timeslot.

Abstract
A communication method is provided for use in a network in which users are allocated respective symbol positions within timeslots for communication to the respective users from a base station. A signal periodically transmitted from at least two antennas of the base station to a user terminal represents coded information. The signal is transmitted within each of a plurality of periodic timeslots. Within each timeslot, each antenna transmits the same coded information only during an assigned symbol position. The symbol positions assigned to the respective antennas are separated in time according to a specified sequential spacing of symbol positions within the timeslot.
