Scalable video coding over simultaneous unicast/multicast LTE DL shared channel
First Claim
1. A method for sending data, the method comprising:
- sending a first configuration to a first WTRU, the first configuration causing the first WTRU to receive one or more multicast transmissions on a downlink shared channel (DL-SCH) based on a group radio network temporary identifier (G-RNTI);
sending a second configuration to a second WTRU, the second configuration causing the second WTRU to receive the one or more multicast transmissions on the DL-SCH based on the G-RNTI;
sending to the first WTRU at least one multicast transmission over the DL-SCH;
sending to the second WTRU the at least one multicast transmission over the DL-SCH;
receiving a first signal-to-noise ratio (first SNR) of the first WTRU;
receiving a second SNR of the second WTRU;
determining a throughput for the at least one multicast transmission based, at least in part, on the lower of the first SNR or the second SNR; and
adjusting at least one of;
a unicast transmission or the multicast transmission based on the determined throughput.

Abstract
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.
