Abstract:
A method is provided that comprises detecting, by a first user terminal of a wireless system, a second user terminal having wireless system information. The wireless system information has timely wireless system parameters. The timely wireless system parameters are collected from the second user terminal. The first user terminal communicates with a base station based on the wireless system parameters.
Abstract:
A method in a wireless communication network (100) wherein information is communicated in a frame structure wherein each frame includes multiple sub-frames, including grouping at least two wireless communication terminals in a group, assigning the group to less than all sub-frames constituting a communication frame, and assigning a radio resource assignment control channel of one or more assigned sub-frames to the group. The control channel is used to assign radio resources to one or more terminals of the group.

A wireless communication network (100) wherein information is communicated in frames comprising multiple sub-frames, including grouping a terminal in first and second groups, assigning the first and second groups to less than all sub-frames in a frame, assigning a control channel of at least one assigned sub-frame to the first and second groups
Abstract:
A base station (105) includes a scheduler (220) to determine a location of a user terminal (110) within a cell (125) of a wireless system (100). The cell has a cell boundary (125). The scheduler (220) also determines a subcarrier frequency diverse resource allocation for a call on the user terminal (110) in response to the location of the user terminal (110) being within a predetermined distance from an edge of the cell boundary (125). The scheduler (220) further determines a subcarrier frequency selective resource allocation for the call on the user terminal (110) in response to the location of the user terminal (110) being beyond a predetermined distance from the edge of the cell boundary. The base station (105) also includes a transceiver (215) to transmit the call according to the subcarrier frequency diverse resource allocation and the subcarrier frequency selective resource allocation.
Abstract:
It is determined whether a first mobile station (102) should receive multicast communications. A control message is sent to at least one of the first mobile station (102) and a second mobile station (104). The control message initiates a mobile relay of multicast communications received at the second mobile station (104) to the first mobile station (102) via a proximal communication technology.
Abstract:
A method for transmitting control information to a wireless node in a communications system includes mapping, by a communications controller, the control information onto resources associated with a wireless node specific search space, the wireless node specific search space being located in a first data region of a first subframe, the first subframe including a first common search space in addition to the wireless node specific search space. The method also includes generating, by the communications controller, a location indicator identifying a location of the wireless node specific search space. The method further includes transmitting, by the communications controller, the first subframe to the wireless node, and transmitting, by the communications controller, the location indicator to the wireless node.
Abstract:
A method of establishing a direct mobile communications (DMC) link between a first user equipment (UE) and a second UE, where at least one of the first UE and the second UE is communicating on a first cellular link includes requesting that at least one of the first UE and the second UE participate in an evaluation procedure to determine a potential quality of a DMC link proposed between the first UE and the second UE. The method also includes receiving a report from at least one of the first UE and the second UE indicating the potential quality of the DMC link proposed between the first UE and the second UE according to the evaluation procedure. The method further includes establishing the DMC link between the first UE and the second UE if the potential quality of the DMC link exceeds a predetermined threshold.
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.
Abstract:
A base station (e.g., an evolved Node B) determines whether the physical broadcast channel (PBCH), reference signals (SCH) and common reference signals (CRS) are transmitted (or awaiting transmission) on a secondary component carrier (Scell) with the cell. The determination information is transmitted to a user equipment (UE) to inform the UE that the Scell transmissions do not include PBCH/SCH/CRS. As a result, the resource elements (REs) normally used to carry system information in the PBCH/SCH/CRS can be dynamically assigned (or reassigned) to the data channel. In this manner, the physical downlink shared channel (PBSCH) bandwidth can be increased by utilizing those resource elements that are normally reserved/assigned to the PBCH/SCH/CRS.
Abstract:
A system and method for adapting code rate are provided. A method for a first communication device to transmit a resource assignment to at least one communication device includes assigning at least one transmission resource to transmit the resource assignment, adapting a code rate of an encoded payload based on the at least one transmission resource and a threshold, thereby producing an adapted payload, and transmitting the adapted payload.
