Claim Text:
1. A method of wireless communication, comprising: identifying a plurality of resource elements (REs) available for transmitting reference signals in at least one resource block (RB) of a subframe, a first set of REs from the plurality of REs being assigned to transmit reference signals and a second set of REs from the plurality of REs being assigned to transmit data, the first set of REs being different from the second set of REs; and assigning REs from the second set of REs to a wireless device in groups of a predetermined number of REs such that all assigned data REs within a group are within a same orthogonal frequency-division multiplexing (OFDM) symbol of a plurality of OFDM symbols of the at least one resource block and each data RE of the group being less than three resource elements away from another data RE of the group, each group of the predetermined number of REs corresponding to a data transmission from a group of antenna ports associated with a transmit diversity scheme.
