METHOD OF UPLINK CONTROL CHANNEL ALLOCATION FOR A RELAY BACKHAUL LINK
First Claim
Patent Images
1. A method, comprising:
- allocating, at an access node, resource blocks in a subframe for a backhaul downlink control channel between the access node and a relay station, wherein the resource blocks are allocated from a first portion of the subframe that is different than a second portion of the subframe allocated to a downlink control channel between the relay station and at least one access terminal; and
transmitting control information from the access node in the resource blocks.

Abstract
The present invention provides a method for uplink control channel allocation for a relay backhaul link. Embodiments of the method include allocating resource blocks in a subframe for a backhaul downlink control channel between an access node and a relay station. The resource blocks are allocated from a first portion of the subframe that is different than a second portion of the subframe allocated to a downlink control channel between the relay station and at least one access terminal. Embodiments of the method also include transmitting control information from the access node in the resource blocks.

9. A method, comprising:
conveying control information over a backhaul interface between an access node and a relay station concurrently with the relay station transmitting a subframe that does not include a common reference signal, wherein the control information is conveyed using resource blocks that are different than resource blocks allocated for transmission of control information by the relay station in the subframe. - View Dependent Claims (10, 11, 12, 13)

14. A method, comprising:
-
generating, at an access node, control information including a scheduling grant in response to receiving a request from a relay station to transmit backhaul information associated with at least one access terminal; configuring, at the access node, a first subframe for transmission of the control information concurrently with the relay station configuring a second subframe that does not include a common reference signal for transmission over an interface between the relay station and at least one access terminal; and transmitting, from the access node, the first subframe concurrently with the relay station transmitting the second subframe, wherein resource blocks are allocated for the control information from a first portion of the first subframe that is different than a second portion of the second subframe allocated to a downlink control channel between the relay station and said at least one access terminal. - View Dependent Claims (15, 16, 17, 18)

19. A method, comprising:
-
configuring, at a relay station, a first subframe that does not include a common reference signal for transmission over an interface between the relay station and at least one access terminal; and transmitting, from the relay station, the first subframe concurrently with receiving a second subframe from an access node in response to the relay station transmitting a request to transmit backhaul information associated with said at least one access terminal, wherein transmitting the first subframe comprises bypassing transmission in resource blocks that are allocated for transmission of control information in the second subframe, the control information comprising a scheduling grant formed in response to the request to transmit backhaul information. - View Dependent Claims (20, 21, 22, 23, 24)
