Method and apparatus for improved data communication in cellular access systems

A user equipment for use in a cellular access system, the user equipment configured for sending and for receiving data blocks to and from a radio base station in the cellular access system, the user equipment being a reporting party with respect to the radio base station, the user equipment comprising:

• a transceiver configured to send a transmission comprising a report, to the radio base station, said report comprising information on whether or not data blocks have been received successfully at the user equipment,
• the transceiver further configured to send said report together with data to the radio base station or to another party in the cell, and
• a processor configured to determine the contents of the report using at least one of the following priority rules which have been given a priority ranking:
• data blocks which have a lower delay tolerance than other data blocks are given priority;
• data blocks which have been detected as received in error, and whose status has not been reported since the error was detected are given priority;
• and
• data blocks are given priority according to their sequence numbers, with lower sequence numbers having priority over data blocks with higher sequence numbers.

A method in a second transceiver for use in a cellular access system, the second transceiver configured for sending and receiving data blocks to and from a first transceiver in the system, the method comprising:

• receiving a transmission comprising a report, from the first transceiver, said report comprising information on whether or not data blocks have been received successfully at the first transceiver, and
• receiving said report together with data from the first transceiver,
• wherein contents of the report are based on using at least one of the following priority rules which have been given a priority ranking:
• data blocks which have a lower delay tolerance than other data blocks are given priority;
• data blocks which have been detected as received in error, and whose status has not been reported since the error was detected are given priority;
• and
• data blocks are given priority according to their sequence numbers, with lower sequence numbers having priority over data blocks with higher sequence numbers.

A second transceiver for use in a cellular access system, the second transceiver configured for sending and for receiving data blocks to and from a first transceiver in the system, the second transceiver comprising:

• a processor configured to control the second transceiver, the second transceiver being configured to receive a transmission comprising a report, from the first transceiver, said report comprising information on whether or not data blocks have been received successfully at the first transceiver,
• the second transceiver being further configured to receive said report together with data from the first transceiver,
• wherein the contents of the report are based on using at least one of the following priority rules which have been given a priority ranking:
• data blocks which have a lower delay tolerance than other data blocks are given priority;
• data blocks which have been detected as received in error, and whose status has not been reported since the error was detected are given priority;
• and
• data blocks are given priority according to their sequence numbers, with lower sequence numbers having priority over data blocks with higher sequence numbers.
