    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.

    Abstract: A method of mapping control information in a wireless communication system is disclosed (FIG. 5). The method includes forming a subframe (FIG. 3) having a bandwidth and having plural regions (302-306). A base station (eNB) determines a communication mode with a remote user equipment. The base station maps control information specific to the user equipment into a first region of the subframe (508). The base station also maps control information common to plural user equipments into a second region of the subframe (512). The subframe is transmitted to the plural user equipments (412, FIG. 4).
