    摘要： Methods, systems and apparatuses for dynamic spectrum access by both primary users (PUs) and secondary users (SUs) are disclosed. In one embodiment, a method for communicating over a channel may include obtaining, at a secondary transmitter, first and second signals intended for a primary receiver and secondary receivers, respectively; generating, at the secondary transmitter, an assist signal based, at least in part, on the obtained first signal; generating, at the secondary transmitter, a data signal based, at least in part, on the obtained second signal; determining, at the secondary transmitter, a power split ratio between the data signal and the assist signal based, at least in part, on any of a power and a signal-to-noise ratio of the first signal; and generating, at the secondary transmitter, a third signal comprising (i) the data signal and (ii) the assist signal in accordance with power split ratio.

    摘要： Embodiments contemplate devices and techniques for receiving unicast and multicast transmissions over a downlink (DL) shared channel in parallel, for example an LTE DL shared channel (SCH). For example, one or more hybrid automatic repeat request (HARQ) entities may be configured to perform retransmissions of the multicast and/or unicast messages. Common and/or dedicated (e.g., separate) HARQ entities may be utilized for retransmission. The multicast downlink shared channels may be activated and/or deactivated on demand. The activation and/or deactivation may be performed using radio resource control (RRC) signaling and/or Medium Access Control (MAC) signaling. The multicast and/or unicast downlink shared channel data may include scalable video coding (SVC) data of varying priority. Embodiments also contemplate the use of simultaneous (e.g. parallel) multicast/unicast for scalable video coding transmission over WiFi/802.11 protocol signals.
