Downlink control channel for relay resource allocation
First Claim
Patent Images
1. A method for wireless communications, comprising:
- allocating resources of a backhaul link between a donor base station and a relay base station to the relay base station for communicating with the donor base station; and
transmitting signaling on a control channel indicating the allocated resources to the relay base station, wherein the signaling on the control channel is transmitted on a subset of physical resource blocks (PRBs) of subframes assigned for downlink communications on the backhaul link, and wherein the control channel is mapped to the subset of PRBs based on a resource allocation type for downlink communications on the backhaul link.

Abstract
Certain aspects of the present disclosure provide a method for wireless communications. The method generally includes allocating resources of a backhaul link between a donor base station and a relay base station to the relay station for communicating with the donor base station and transmitting a control channel indicating the allocated resources to the relay base station, wherein the control channel is transmitted on a subset of physical resource blocks (PRBs) of subframes assigned for downlink communications on the backhaul link.
