Abstract
Disclosed is a method and system for compensating excessive delay spread in uplink coordinated multipoint service. An uplink data-unit transmitted by a user equipment device (UE) on a first uplink air interface to a first base station (BS) using a first group of sub-carrier frequencies may be received at a time that is within an alignment-time range for simultaneously decoding uplink data-units from UEs transmitting on the first uplink. A determination is made that the uplink data-unit transmitted simultaneously by the UE on a second uplink air interface using a second group of sub-carrier frequencies will be received at a second BS at a time that is time is beyond the alignment-time range for simultaneously decoding uplink data-units from UEs transmitting on the second uplink. Decoding of the received uplink data-unit at the second BS is then delayed until a start time beyond the end of the alignment-time range.
