摘要:
A method for minimizing the loss of data and ensuring that large delays do not occur during reconfigurations of an uplink transmission time interval (TTI) length of a WCDMA High Speed Packet Uplink Access (HSUPA) air interface, wherein the reconfiguration of an uplink TTI length is delayed until all pending retransmissions are successfully transmitted or until the maximum number of transmissions is reached. The transmission of new packets during this time period is prevented. However, pending retransmissions are allowed to occur. After the UE has received an ACK/NACK for each HARQ process, or until the specific maximum number of re-transmissions is reached, the UE starts transmitting with a new uplink TTI length.

A method includes, in response to selection of a transport block to be transmitted through a wireless channel at a current data rate, performing at least the following: selecting a size for a data unit that can be scheduled for transmission; identifying one of a number of potential transport blocks, the identified potential transport block having a corresponding transport block size large enough to hold at least the selected size of the data unit and the transport block size of the currently selected transport block; determining whether the identified potential transport block is available for transmission; and transmitting a request for an increase in the current data rate in response to the identified potential transport block being available for transmission.

The definition and use of an additional timer for the MAC-hs reordering function in a user equipment. The timer counts transmission time intervals and is reset each time that the user equipment receives a data packet. If the timer reaches a set value, indicating a sufficiently long period of inactivity, then the transmission sequence number is reset to zero or another predefined value. A base station can run a similar timer and, after the timer reaches a set value, can consider the user equipment as no longer being active.

A radio resource control in an HSUPA system is provided. The control procedure includes: communicating data blocks between user equipment and a network infrastructure over a physical High Speed Uplink Packet Access channel; communicating block acknowledgement messages between the user equipment and the network infrastructure, each block acknowledgement message indicating whether or not a data block was received successfully; and controlling transmission power of the physical HSUPA channel on the basis of at least one block acknowledgement message.

A radio network element, including means for receiving data packets from a user equipment in a soft handover connection, means for determining whether the received data blocks have been received successfully or unsuccessfully, means for running a retransmission process for an un-successfully received data packet, and means for receiving control information instructing the size of memory to be reserved for retransmission processes of the connection.

摘要:
This invention relates to signalling of control information related to retransmissions in a wireless communication network. According to one aspect of the invention, a method for controlling transmission over a wireless communication link is provided. The method comprises the step of indicating on a transmission resource control channel whether a HARQ retransmission process in a mobile station should be activated or deactivated.
