User equipment for physical layer automatic repeat request
Abstract
A subscriber unit for automatic repeat request mechanisms and related methods are disclosed. The subscriber unit may comprise transmitting a single carrier frequency domain equalization (SC-FDE) signals using a plurality of hybrid automatic repeat request (ARQ) mechanisms. The plurality of hybrid ARQ mechanisms may use a stop and wait architecture. Further, each of the plurality of hybrid ARQ mechanisms may transmit in a different time interval and each time interval includes at least one time slot. The subscriber unit may receive downlink data signals using hybrid ARQ and may receive acknowledgments (ACKs)/negative acknowledgments, wherein the ACK/NAKs may be received in a time period between the downlink transmissions.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A subscriber unit comprising:
a receiver; a transmitter; and a controller; and the controller and the transmitter are configured to transmit single carrier frequency domain equalization (SC-FDE) signals, wherein the SC-FDE signals are transmitted using a plurality of hybrid automatic repeat request (ARQ) mechanisms, wherein the plurality of hybrid ARQ mechanisms use a stop and wait architecture, wherein each of the plurality of hybrid ARQ mechanisms transmit in a different time interval, wherein each time interval includes at least one time slot; and the controller and the receiver are configured to receive downlink data signals using hybrid ARQ and to receive acknowledgements (ACKs)/negative acknowledgements (NAKs), wherein the ACK/NAKs are transmitted in a time period between the downlink transmissions.
2 . The subscriber unit of claim 1 wherein data transmitted in one of the SC-FDE signals is turbo coded.
3 . The subscriber unit of claim 2 wherein a retransmission of the transmitted data uses a different encoding than the original transmission.
4 . The subscriber unit of claim 1 wherein a modulation and coding varies between SC-FDE signal transmissions.
5 . The subscriber unit of claim 4 wherein modulation schemes include QPSK, 16-QAM and 64-QAM.
6 . The subscriber unit of claim 1 wherein SC-FDE resources vary between SC-FDE signal transmissions.
7 . The subscriber unit of claim 1 wherein an error check sequence is appended to data of a SC-FDE transmission.
8 . The subscriber unit of claim 1 wherein each hybrid ARQ mechanism is assigned a maximum number of retransmissions.
9 . A method for a subscriber unit comprising:
transmitting a single carrier frequency domain equalization (SC-FDE) signals using a plurality of hybrid automatic repeat request (ARQ) mechanisms, wherein the plurality of hybrid ARQ mechanisms use a stop and wait architecture, and wherein each of the plurality of hybrid ARQ mechanisms transmit in a different time interval and each time interval includes at least one time slot; receiving downlink data signals using hybrid ARQ; and receiving acknowledgements (ACKs)/negative acknowledgements (NAKs), wherein the ACK/NAKs are received in a time period between the downlink transmissions.
10 . The method of claim 9 , wherein data transmitted in one of the SC-FDE signals is turbo coded.
11 . The method of claim 10 , wherein a retransmission of the transmitted data uses a different encoding than the original transmission.
12 . The method of claim 9 , wherein a modulation and coding varies between SC-FDE signal transmissions.
13 . The method of claim 12 , wherein modulation schemes include QPSK, 16-QAM and 64-QAM.
14 . The method of claim 9 , wherein SC-FDE resources vary between SC-FDE signal transmissions.
15 . The method of claim 9 , wherein an error check sequence is appended to data of a SC-FDE transmission.
16 . The method of claim 9 , wherein each hybrid ARQ mechanism is assigned a maximum number of retransmissions.Join the waitlist — get patent alerts
