Method of harq retransmission timing control

A method for controlling the transmission timing of data retransmissions in a wireless communication system, wherein a HARQ protocol is used with synchronous retransmissions from a transmitting entity to a receiving entity via a data channel, and wherein the receiving entity performs the method steps of:

• receiving a data packet from the transmitting entity, determining whether the data packet has been successfully decoded,
• if it has been determined that the data packet has not been successfully decoded, transmitting a feedback message to the transmitting entity, wherein the feedback message indicates to the transmitting entity to transmit a retransmission data packet for said received data packet after a predetermined time span upon having received said feedback message,
• scheduling data transmissions of a plurality of transmitting entities comprising said transmitting entity, and
• transmitting a common control message to a plurality of transmitting entities comprising said transmitting entity, wherein the common control message restricts the transmission format combination subset of each of the plurality of transmitting entities to determine a maximum resource common to the plurality of transmitting entities.

A base station in a wireless communication system wherein a HARQ protocol is used with synchronous retransmissions from a transmitting entity to a receiving entity via a data channel, the base station comprising:

• a receiver operable to receive a data packet from the transmitting entity,
• a determining unit operable to determine whether the data packet has been successfully decoded,
• a transmitter operable to transmit a feedback message to the transmitting entity, if it has been determined that the data packet has not been successfully decoded, wherein the feedback message indicates to the transmitting entity to transmit a retransmission data packet for said received data packet after a predetermined time span upon having received said feedback message,
• a scheduler operable to schedule data transmissions of a plurality of transmitting entities comprising said transmitting entity,
• wherein said transmitter is operable to transmit a common control message to a plurality of transmitting entities comprising said transmitting entity, wherein the common control message restricts the transmission format combination subset of each of the plurality of transmitting entities to determine a maximum resource common to the plurality of transmitting entities.

A method for controlling the transmission timing of data retransmissions in a wireless communication system, wherein a HARQ protocol is used with synchronous retransmissions from a transmitting entity to a receiving entity via a data channel, and wherein the transmitting entity performs the method steps of:

• transmitting a data packet to the receiving entity,
• receiving a feedback message from receiving entity and a common control message,
• retransmitting the data packet to the receiving entity after a predetermined time span upon having received said feedback message,
• restricting the transmission format combination subset of the mobile terminal to determine a maximum resource according to the common control message.

A mobile terminal in a wireless communication system wherein a HARQ protocol is used with synchronous retransmissions from a transmitting entity to a receiving entity via a data channel, the mobile terminal comprising:

• a transmitter operable to transmit a data packet to the receiving entity,
• a receiver operable to receive a feedback message from the receiving entity and a common control message,
• wherein the transmitter is operable to retransmit the data packet to the receiving entity after a predetermined time span upon having received said feedback message,
• a restricting unit operable to restrict the transmission format combination subset of the mobile terminal to determine a maximum resource according to the common control message.
