Abstract

Embodiments of the invention provide methods for maximizing the bandwidth utilization in the uplink of a communication system supporting time division multiplexing between unicast and multicast/broadcast communication modes during transmission time intervals in the downlink of a communication system. This is accomplished by multiplexing at least unicast control signaling for UL scheduling assignments in TTIs supporting the multicast/broadcast communication mode. Moreover, multiplexing of unicast control signaling can also be accomplished by splitting a symbol of the multicast/broadcast TTI into two shorter symbols with the first of these two shorter symbols carrying at least unicast control signaling and the second of these shorter symbols carrying multicast/broadcast signaling.

Claims15

Dependent claims

A method for a base station to schedule a data transmission from a User Equipment (UE) wherein said scheduling occurs in a broadcast/multicast Transmission Time Interval (TTI), said method comprising:

partitioning the multicast/broadcast TTI in two consecutive sets of symbols with the first set of symbols is placed prior to the second set of symbols;
transmitting, from said base station, unicast signaling in said first set of symbols of said multicast/broadcast TTI, said unicast signaling comprising only unicast control signaling and unicast pilot signaling;
transmitting, from said base station, multicast/broadcast signaling in said second set of symbols of said multicast/broadcast TTI, said multicast/broadcast signaling comprising only multicast/broadcast data signaling and multicast/broadcast pilot signaling;
transmitting, from said base station, unicast data signaling in a TTI in response to the reception of said unicast control signaling in said broadcast/multicast TTI, wherein said unicast control signaling is
transmitted with priority to multicast/broadcast signaling at the beginning of said multicast/broadcast TTI.
