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.

User specific load balancing

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. In operation often the first group of communication resource units will be available to perform retransmission operations in the second time period. In such a manner a non-adaptive HARQ retransmissions can be accommodated in a 3GPP LTE OFDM based wireless communications system.
