Abstract
Official abstract text for this publication.
Providing for wireless communication involving supplemental wireless nodes is described herein. By way of example, prior signaling is employed between a macro base station and a set of associated supplemental nodes to support pending wireless communication with a user terminal. In some aspects, the prior signaling can include control or data traffic transmitted to or received from the user terminal. In addition, the supplemental nodes can synchronize transmission or reception of the control or data traffic transmissions with similar transmission or reception of the macro base station. In some aspects, the supplemental nodes can also replicate pilot signal transmissions on OFDM symbols employed by the macro base station for pilot signals, to give consistent downlink channel for both traffic and pilot signals. Accordingly, the user terminal observes consistent pilot transmissions over various time slots, as well as concurrent traffic transmissions that can generally be decoded with a common reference signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for employing a half duplex supplemental wireless node (HD-SWN) in wireless communication, comprising: transmitting a relay pilot signal to a user equipment (UE) on a first set of orthogonal frequency division multiplex (OFDM) symbols in a subframe; receiving from a base station a wireless signal on a second set of OFDM symbols within the subframe, at least one OFDM symbol of the second set of OFDM symbols being interposed between at least two OFD…
