ABSTRACT:
Signalling uplink and downlink scheduling grants for a plurality of subframes in a time division duplex frame is addressed. In one aspect the allocated uplink subframes are divided into groups, so the number of groups equals the number of downlink subframes being allocated. Uplink grants for the groups are sent with the downlink grants, and for those groups that have more than one uplink subframe, the grant message also indicates which uplink subframes are included in that group. In another aspect there are two sets of grant messages, one for the uplink subframes and one for the downlink subframes. Each of the uplink grant messages is sent on a different uplink grant message, and there is a one-to-one correspondence between the uplink grant channel and the uplink subframe being scheduled by the grant. That correspondence may also be signalled with the grant messages.
