    摘要： Communication signals using a first and a second frequency band in a wireless network is described herein. The first frequency band may be associated with a first beamwidth while the second frequency band may be associated with a second beamwidth. A method includes transmitting, in a first frequency band by a coordinating device, an indication of a first time resource and/or first frequency resource for a communication device to identify one or more neighbor communication devices that are capable of communicating over a second frequency band, receiving, in the first frequency band by the coordinating device, link availability information for the second frequency band based at least in part on the one or more neighbor communication devices identified as being capable of communicating over the second frequency band, and transmitting, in the first frequency band, a transmission schedule to indicate to the communication device a second time resource and/or second frequency resource in which the communication device can communicate with at least one of the one or more neighbor communications devices over the second frequency band, the transmission schedule being based at least in part on the received link availability information. Other embodiments may be described and/or claimed.

    摘要： In a wireless, OFDM system, phase noise may be mitigated through the use of an interleaver that is designed to distribute coded block bits across subcarriers of multiple OFDM symbols. Doing so decreases the non-stationary properties of the noise. Such an interleaver may be a rectangular interleaver that maps each block to a different subcarrier to create frequency diversity and to a different OFDM symbol, to create time diversity. One exemplary method of interleaving the symbols is to place a first symbol at row X and column Y of the interleaver. The next symbol is placed in row X+1 and column Y+1. The result of such an interleaving process is a great reduction in the block error rate.
