摘要： Techniques are provided for managing simultaneous unicast and multicast/broadcast services. For example, there is provided a method operable by a user equipment (UE) or the like, that involves transmitting, upon initial connection with a wireless communication system, a first message indicating one or more capabilities of the UE. The method may further involve transmitting a second message indicating that the UE is receiving or is about to receive a multicast/broadcast service. The method may also involve receiving, as a result of the second message, data scheduled in accordance with one or more predetermined rules.

摘要： A network entity may dynamically control Quality-of-Service (QoS) for a multicast transmission in a wireless communications system, by initiating a multicast transmission having an initial QoS, and later during the multicast transmission, generating an updated QoS for the multicast transmission. The network entity may generate the updated QoS in response to a network load factor for a multicast area aggregated from base stations in the area. The network load factor may indicate a measure of aggregate available bandwidth in the multicast area. The network entity may provide the updated QoS to mobile entities receiving the multicast transmission, which may process a subsequent portion of multicast content according to the updated QoS.
