Abstract:
Communications sourced by a remote unit (14) that is already within reception range of a base site (10) can nevertheless be further facilitated through allocation of one or more relay resources (15, 16). Such relay resources, properly employed, then serve to effectively increase the quality of service for the facilitated communication. This, in turn, can permit the use of, for example, increased data rates for communications from a relatively low power remote unit.
Abstract:
A method and system for dynamic rate switching via medium access channel layer signaling is disclosed, wherein data rates for high data rate channels are automatically shifted up or down based on a predetermined metric. In a preferred embodiment, data rates are automatically shifted up or down based on transmit channel gain required to maintain a required signal to noise ratio.
Abstract:
A squished trellis encoder encodes blocks of information with unequal error correction. A multiplexing switch partitions the information block into a first portion and a second portion. A first trellis encoder encodes the first portion. A second trellis encoder encodes the second portion. An initial state information generator maps the states of the first trellis encoder to the second trellis encoder to establish initial conditions for the states of the second trellis encoder. A delay delays the second portion from processing by the second trellis encoder until the initial state information generator has mapped the states. An associated decoder can use the novel squished approach or other alternative approaches.
Abstract:
A method for operating a user equipment (UE) in a UE group including at least two UEs includes receiving, from a communications controller, network resources information about an allocation of a first set of network resources to the UE group and a transmission indication, where the transmission indication indicates that the UE is selected to transmit in a second set of network resources that is a subset of the first set of network resources. The method further includes transmitting, to other UEs in the UE group utilizing a direct mobile communications (DMC) link associated with the communications controller, a first message including a control indicator in a first subset of the second set of network resources, the control indicator indicating scheduling information for a second subset of the second set of network resources.

A communications system and a method for performing communications are provided. User Equipments (UEs) are provided with UE-specific configuration information, such as CSI-RS (Channel Status Indication-Reference Signal) patterns, antenna port groupings, reference signal configurations, subframe configurations, and/or scrambling codes. The UEs process the received reference signals in accordance with the received configuration information and feedback measurement information for, e.g., PMI/CQI/RI (Precoding Matrix Indicator/Channel Quality Indicator/Rank Indicator of the precoding matrix) and/or the RLM/RRM (Radio Link Monitor/Radio Resource Management).

A system and method for relaying transmissions in wireless communications is provided. A method for combined relay node operation includes determining an operating mode of the combined relay node, where the combined relay node includes a repeater and a relay. The method also includes if the operating mode is repeater on mode, amplifying and forwarding received signals, and storing subframes, where subframes are demodulated and decoded versions of the received signals. The method further includes if the operating mode is repeater off mode, amplifying and forwarding a control zone of signals received while the operating mode is repeater off mode, and transmitting subframes stored while the operating mode is repeater on mode.
