Abstract:
A method and apparatus are described including transmitting a request-to-send signal, determining if a clear-to-send signal and a reverse direction transmission request signal have been received, transmitting first data, a first block acknowledgement request signal and a reverse direction grant signal responsive to the first determination, determining if a first block acknowledgement signal, second data and a second block acknowledgement request signal have been received, transmitting a second block acknowledgement signal responsive to the second determination, determining if a third block acknowledgement signal has been received and transmitting a fourth block acknowledgement signal responsive to the third determination. Further described are a method and apparatus including listening to channels, estimating channel conditions responsive to the listening, determining if a signal has been received, determining if channel conditions are adequate to act as a relay node multicasting a relay node clear to send signal responsive to the first and second determinations and multicasting a block acknowledgement signal and data responsive to the first and second determinations.

Abstract:
Techniques for inter-cell interference cancellation are disclosed. At each transmitter, the data (message) may split into two or more layers, (e.g., common and private parts), and may be encoded in different rates, allocated with different powers, possibly beamformed using different precoders, and transmitted through the same physical channels. The common part is to be decoded at both the intended and unintended users, while the private part is to be decoded at the intended user.

Abstract:
A method and apparatus are described including receiving a first signal including first data in a first time slot of a first channel, receiving a second signal including second data in a second time slot of a second channel, determining a first pre-coding matrix, determining a second pre-coding matrix, applying the first pre-coding matrix to the first data to produce pre-coded first data, applying the second pre-coding matrix to the second data to produce pre-coded second data, generating a third signal by combining the pre-coded first data and the pre-coded second data and transmitting the third signal on the first channel and on the second channel. Also described are a method and apparatus including transmitting a first signal, receiving a second signal including a first training sequence and decoding the second signal by removing the first training sequence and removing the first signal.
