Abstract
A transmission of information between a secondary to a primary node in a wireless network occurs in a plurality of N logical time durations. Bundled feedback information for multiple DL transmissions is provided in one UL transmission. Each DL transmission is indicated by a DL grant comprising an M-bit downlink assignment indicator (DAI) field. The primary node increments the value of the M-bit DAI field in successively transmitted DL grants. The secondary node examines the value of the M-bit DAI field in received DL grants, to determine the bundled feedback information.
Claims23
A method for providing bundled feedback in a wireless network, comprising:
- receiving one or more downlink (DL) grants indicative of one or more corresponding DL packets, wherein each DL grant comprises a downlink assignment indicator (DAI);
- determining if at least one DL grant was missed using the one or more received downlink assignment indicators;
- and
- generating a bundled feedback for the one or more received DL packets.
An apparatus for providing bundled feedback in a wireless network, comprising:
- processing circuitry coupled to receiving circuitry and to transmitting circuitry,
- wherein the receiving circuitry is operable to receive one or more downlink (DL) grants indicative of one or more corresponding DL packets, wherein each DL grant comprises a downlink assignment indicator (DAI);
- wherein the processing circuitry is operable to determine if at least one DL grant was missed using the one or more received downlink assignment indicators;
- and
- wherein the transmitting circuitry is operable to generate a bundled feedback for the one or more received DL packets.
A method for receiving bundled feedback in a wireless network, comprising:
- transmitting to a user equipment (UE) one or more downlink (DL) grants indicative of one or more corresponding DL packets, wherein each DL grant comprises a downlink assignment indicator (DAI);
- transmitting to the UE one or more blocks of data using a set of resource blocks indicated by the one or more DL grants;
- receiving from the UE a bundled acknowledgement for the one or more blocks of data in an uplink transmission instance corresponding to the one or more DL grants;
- and
- determining that at least one DL grant was missed by the UE when the bundled acknowledgement is received on a channel that does not correspond to the last transmitted DL grant.
