Abstract:
1. A method for wireless communication at a half-duplex node operating in TDD mode, comprising; receiving a configuration of a first set of subframes for a first link communication selected among a plurality of configurations, wherein the first set of subframes contains at least one downlink subframe and at least one uplink subframe; determining a second set of subframes for a second link communication, wherein there is at least one backward compatible downlink hybrid automatic repeat request process and at least one backward compatible uplink hybrid automatic repeat request process requiring the second set of subframes; communicating with a first set of nodes using the first link and the first set of subframes; and communicating with a second set of nodes using the second link and the second set of subframes, wherein the communication to a legacy node uses the at least one backward compatible downlink hybrid automatic repeat request process and the at least one backward compatible uplink hybrid automatic repeat request process, wherein the plurality of configurations include a configuration of an initial set of subframes for the first link communication and a configuration of at least one additional set of subframes generated by removing from the initial set at least one of a downlink subframe most compatible with an uplink subframe in the second link communication or an uplink subframe most compatible with a downlink subframe in the second link communication, wherein compatibility is with respect to timing between a downlink channel and an uplink channel.
