Abstract: It is provided a solution for selecting the length of a transmission time interval for high-speed packet radio communications between a base station and a mobile station. The length of the transmission time interval used in data transfer is selected on the basis of channel conditions between the mobile station and the base station. An average value for a channel quality metric representing the channel conditions is calculated and the calculated average value of the channel quality metric is associated with a pre-determined length of the transmission time interval. That length of the transmission time interval is then selected for the data transfer between the mobile station and the base station.

Abstract: Resources are allocated on a shared downlink control channel by an allocation table that is partitioned into a first, fixed length partition and into at least one second, variable length partition. The fixed length and the modulation and coding scheme MCS of the first partition is known a priori. The second variable length and the MCS of the second partition may be given in the first partition. Robustness may be varied between different second partitions of the same allocation table, or even within a single second partition to account for users at different proximity to the network node giving the allocations. Users may be identified in the first partition (e.g., a fixed number of users), and/or in the second partition (either additional allocated users or all users being allocated if the first partition does not identify users). Method, apparatus, computer program, integrated circuit and systems are detailed.

Abstract: A radio link service profile is defined as a set of parameters for upper layer transport of an IP packet, and may be associated with a logical channel flow identifier. A data packet is sent over a wireless logical channel that is identified by the LCID between a base station and a user equipment.

A method, device (both BS and UE), computer program product, and system are described in multiple embodiments.

Abstract: A method for implementing a stall avoidance mechanism during uplink transmission of data blocks from transmitter to a receiver includes first determining a missing data block in response to a successful receipt of a received data block at the receiver. Once the missing data block is determined, the receiver requests retransmission of the missing data block. The receiver starts a timer when the request for retransmission is made such that the timer has a time value based on the number of reception attempts of the received data block made by the receiver.

A corresponding method, apparatus, system and computer programs are shown.
