Abstract:
This invention measures the propagation delay τ1 between the user equipment and a first cooperating unit and the propagation delay τ2 between the user equipment and a second cooperating unit. These propagation delays are used to compute a timing advance amount to the user equipment to enable coordinated multi-point reception. In a first embodiment one cooperating unit receives a function of the propagation delay, computes the timing advance amount and transmits a timing advance command to the user equipment. In a second embodiment a central unit performs these operations.
