    摘要: A user equipment 502 is provided that includes a processor 602 programmed responsive to receiving a point-to-multipoint (PTM) broadcast of a service at a low quality, to request a point-to-point (PTP) communication from the network 100. A method is provided for user equipment 502 to receive a service. The method includes receiving a point-to-multipoint (PTM) broadcast of a service from a network 100, and attempting to obtain an improved quality of the service by requesting from the network 100 a point-to-point (PTP) communication of the service

    摘要: Systems and methods for performing MCS adaptation are provided. In some cases, the network performs MCS adaptation based on received NACKs. In other cases, the mobile station determines an MCS based on channel quality measurements, and feeds back the MCS adaptation decision to the network. In either case, NACK-only feedback may be implemented to reduce interference.

    摘要: A system and method are disclosed that allow changes of a modulation and coding scheme (MCS) without overhead signaling. A priori, a network device and a user device know the manner in which the MCS will be changed. In one embodiment, the network device indicates the MCS to be used to decode a second portion of a message in a first portion of the message. In another embodiment, the user device blind detects the MCS used over a sub-set of MCSs.
