Abstract:
A system and method for distributed scheduling of transmissions between device-to-device (D2D) communications is disclosed. The distributed scheduling method employs a distributed scheduling structure in which device identifiers rather than connection identifiers are used to enable scheduling of a D2D data transfer between devices in a wireless neighborhood. The novel distributed scheduling structure is scalable to a larger number of D2D devices than is feasible with a connection ID-based tone matrix.
Abstract:
An apparatus and method for processing fast feedback payload data to generate symbols for transmission through a fast feedback channel in a wireless network are presented. The technique first encodes payload data using a tail biting convolutional code. The encoded bits are then de-multiplexed to five different data subblocks in a sequential fashion. Subblock interleaving is then used to interleave the data of the subblocks according to a predetermine scheme. A bit selector then selects interleaved subblock bit for output. The selected bits may then be modulated by a modulator using quadrature phase shift keying (QPSK). The resulting symbols may then be mapped to a predetermined fast feedback subcarriers within a feedback channel.
Abstract:
A method for an uplink power control mechanism is presented. In one embodiment, the method includes receiving an allocation information element (IE) in conjunction with a ranging process. The method includes processing the allocation information element to determine power control parameters including a first parameter about offset control and a second parameter about noise and interference level. The method also includes calculating the power value for each channel based at least in part on two or more power control parameters.
Abstract:
Embodiments of computer-implemented methods, systems, computing devices, and computer-readable media are described herein for monitoring, by a mobile proxy associated with a control system of a cloud radio access network (“C-RAN”), application layer data traffic between the control system and a wireless communication device. In various embodiments, the mobile proxy may, based on the monitoring, facilitate alteration of data plane or control plane processing by the wireless communication device or a remote radio head (“RRH”) associated with the C-RAN.
Abstract:
Embodiments of the present invention provide an uplink open loop power control system in which interference over thermal information is transmitted to mobile stations. Other embodiments may be described and claimed.
Abstract:
Group size indications may be distributed from a base station to a mobile station in the form of assignment-advanced-MAP transmit control signaling. The signaling control information may be sent to a station, such as a mobile station, using a table that indicates the size of a group based on coding rates, such as one-half and one-quarter coding rates. Waste may be controlled by determining a size based on using an unoccupied resource in a group that is adjacent to data resource for data transmission by the station. However, an unoccupied resource in a group that is not adjacent to a data resource is not used for data transmission and is, therefore, wasted.
Abstract:
A carrier aggregation power headroom reporting method is disclosed. User equipment selects from one of four possible definitions of a single parameter used to calculate the power headroom of the user equipment. The user equipment uses the parameter to calculate the power headroom for two different equations. The two results are transmitted to the enhanced base station.
Abstract:
A signal structure for use in D2D communications is described. In one embodiment, a preamble for automatic gain control at the receiver end is included in the transmitted signal. Techniques for scheduling of D2D transmissions using carrier sensing multiple access (CSMA) and a power control schemes for interference management are also described.
Abstract:
Uplink power control in a macro cell in a wireless network comprises transmitting a reference signal from a base station device to at least one wireless device within the macro cell. The macro cell comprises the base station device and at least one radio transmitter device that is communicatively coupled to and remote from the base station device. The base station device and one or more radio transmitter devices could be selected to be a transmission point, a reception point or a combination thereof, for each wireless device. Information relating to a transmission power of the base station device is also transmitted to the at least one wireless device. An uplink signal is received from the at least one wireless device containing information relating to an uplink power determination that is based on the reference signal and the information relating to the transmission power of the base station device.
Abstract:
A base station may transmit at varied power levels. Subscriber stations receiving the power levels can transmit noise information back to the base station. As a result, co-channel interference can be determined from the varied power transmissions, either in the base station or in the subscriber station. In addition, in some embodiments, the transmissions may include different phases so that the phase of the co-channel interference may be determined as well.
