PRE-COMMUNICATION FOR RELAY BASE STATIONS IN WIRELESS COMMUNICATION
First Claim
1. A method for employing a half duplex supplemental wireless node (a HD-SWN) in wireless communication, comprising:
- transmitting a signal on a first set of orthogonal frequency division multiplex symbols (a first set of OFDM symbols) in a third generation partnership project long term evolution signal subframe (an LTE signal subframe); and
receiving a wireless signal on a second set of OFDM symbols within the LTE signal subframe, wherein at least one OFDM symbol of the second set of OFDM symbols is interposed in time between at least two OFDM symbols of the first set of OFDM symbols that are non-contiguous in time.

Abstract
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.
