  • Patent number: 8429480
    Abstract: In accordance with exemplary embodiments of the invention there is a method and apparatus to detect with a hybrid automatic repeat request function a collision between an uplink packet re-transmission and a new uplink packet transmission within a hybrid automatic repeat request process, and in response, to dynamically allocating resources for transmitting the new uplink packet transmission in a different hybrid automatic repeat request process that does not collide with the uplink packet re-transmission. In accordance with other exemplary embodiments of the invention, there is a method and apparatus to transmit a packet re-transmission in a hybrid automatic repeat request process using a semi-persistently scheduled uplink resource, and responsive to receiving a dynamic allocation of a different hybrid automatic repeat request process, to transmit a new packet using the dynamically allocated different hybrid automatic repeat request process.

  • Patent number: 7873011
    Abstract: 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.

  • Publication number: 20100202376
    Abstract: 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.
