摘要： Methods and apparatus operative in a wireless communications system divide a communications resource available for performing information transmission and retransmission operations into a plurality of communication resource units. The units are ordered in a predetermined order. A first group of communication resource units are selected from the communication resource in ascending order and assigned to a first group of communications devices to perform information transmission operations in a first time period. A second group of communication resource units are selected from the communication resource in descending order and assigned to a second group of communications devices to perform information transmission operations in a second time period. At least a portion of the first group of communication resource units is assigned to the first group of communication resource units to perform retransmission operations, hi operation often the first group of communication resource units will be available to perform retransmission operations in the second time period, hi such a manner a non-adaptive HARQ retransmissions can be accommodated in a 3GPP LTE OFDM based wireless communications system.

摘要： Singalling 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.

摘要： Voice over Internet Protocol (VoIP) transfer is provided over radio links between mobile stations and base stations with a mechanism to schedule initial transmission within voice spurts when semi-persistent allocation of radio resources is employed. The radio link is changed during the voice spurt by allocating different physical resource blocks or by changing transmission parameters with given rescheduling intervals. The scheduling is informed from the base station to involved MS by using data link layer VoIP packet padding bits. The radio link can also be changed per initiative of the MS so that the MS codes a predetermined request into data link layer padding bits of an uplink VoIP packet. The requests from the MS typically involve a change of audio coding mode or informing of the present packet buffer status for VoIP packets at the MS.
