Abstract
Disclosed is a method and system for adjusting a transport block size used for uplink transmissions from a user equipment device (UE) when engaging in uplink coordinated multipoint service (UL CoMP), under conditions in which a propagation delay to a receiving CoMP base station (BS) exceeds a threshold. Based on predicted delay reported to a serving BS from the CoMP BS, the serving BS may compute a reduced transport block size such that uplink resource blocks transmitted from the UE to the CoMP base station will be temporally under-filled by an amount corresponding to the predicted delay. As received at the CoMP BS, the under-filled resource blocks will not overrun their assigned transmission time interval (TTI), and therefore will not be a source of potential interference.
