Abstract
A method for wireless communication comprises a donor enhanced Node B (eNB) transmitting system information for a subframe structure to a relay node (RN), which information comprises radio resource configuration and/or timing information for uplink backhaul transmission. The RN uses an automatic method to select the Round Trip Time (RTT) value for the Hybrid Automatic Repeat request (HARQ) on the uplink backhaul (Un) relay link. The RTT value is implicitly determined according to the Un (backhaul) subframe or MBSFN subframe configuration periodicity. The RTT option is signaled by the Un subframe configuration period of the MBSFN Un downlink signals.
Claims27
A method of a wireless network communication comprising:
- selecting, by a central controller, a resource allocation scheme from a plurality of resource allocation schemes, wherein the resource allocation scheme comprises a first round trip time (RTT) for a hybrid automatic repeat request (HARQ) protocol;
- selecting a period of a subframe pattern in accordance with the selected first RTT for the HARQ protocol;
- and
- transmitting, by the central controller, a system configuration information of the subframe pattern to a communication device.
A method of a wireless network communication comprising:
- receiving, by a communication device, a system configuration information of a subframe pattern from a central controller;
- determining a period of the subframe pattern in accordance with the system configuration information;
- selecting, by the communication device, a resource allocation scheme in accordance with the determined period of the subframe pattern, from a plurality of resource allocation schemes, wherein the resource allocation scheme comprises a first round trip time (RTT) for a hybrid automatic repeat request (HARQ) protocol;
- and
- setting up, by the communication device, a communication between the communication device and the central controller in accordance with the selected resource allocation scheme.
An apparatus for a wireless communication system, comprising:
- a resource allocation selector configured to select a resource allocation scheme from a plurality of resource allocation schemes, wherein the resource allocation scheme comprises a first round trip time (RTT) for a hybrid automatic repeat request (HARQ) protocol, and to select a subframe resource allocation message period in accordance with the selected first RTT for the HARQ protocol;
- an encoder configured to encode the selected subframe resource allocation message period by a bitmap;
- and
- a transmitter configured to transmit the bitmap to a communication device.
