Systems and methods for performing MCS adaptation are provided. In one embodiment, the network (20-3) performs (5-3) MCS adaptation based on received ACKs. In another embodiment, the MCS adaptation is based on the number of received ACKs.

A method and system, in a long term evolution architecture utilizing adaptive modulation and coding requiring periodic channel quality indication reports, the method having the steps of: waiting for an idle channel indication; and upon detection of the idle channel indication, decreasing the rate of periodic channel quality indication reports.

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.

Methods of combining semi-persistent resource allocation and dynamic resource allocation are provided. Packets, such as VoIP packets, are transmitted on the uplink and downlink using respective semi-persistent resources. For each mobile device, awake periods and sleep periods are defined. The semi-persistent resources are aligned with the awake periods so that most of the time the mobile device can turn off its wireless access radio during the sleep periods. In addition, signalling to request, and to allocate, resources for additional packets are transmitted during the awake periods, and the resources allocated for the additional packets are within the awake windows.

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.

A user agent comprising a processor enabled to configure the user agent to adjust a discontinuous reception (DRX) start offset when a downlink assignment is one of configured and reconfigured. The DRX start offset is adjusted to satisfy the equation 10 * SFNstart time + subframestart time modulo Long DRX Cycle = DRX start offset .
