摘要:
A method and apparatus for subcarrier selection for systems is described. In one embodiment, a method for subcarrier selection for a system employing orthogonal frequency division multiple access (OFDMA) comprises partitioning subcarriers into groups of at least one cluster of subcarriers, receiving an indication of a selection by the subscriber of one or more groups in the groups, and allocating at least one cluster in the one or more groups of clusters selected by the subcarrier for use in communication with the subscriber.

An apparatus may include a processor circuit and a communication scheduling module operable on the processor circuit to receive a first set of terminal information of a first terminal transceiver, and a second set of terminal information of a second terminal transceiver, determine whether the first and second terminal transceivers are co-located in a radio terminal based on the first and second sets of terminal information, and schedule first and second radio-frequency (RF) communications with the first and second terminal transceivers, respectively, of the radio terminal to reduce interference between the first and second communications when the first and second terminal transceivers are co-located within the radio terminal. Other embodiments are disclosed and claimed.

A network having distribution of access point loading includes access points to which mobile stations can associate themselves based upon access point beacon signal levels and loading levels for the various access points. A mobile station receives beacon signals from various access points and determines a signal strength for the received beacon signals. The mobile station also receives access point loading information from the access points. The mobile station associates with an access point based upon the access point beacon signal strengths and the access point loading information.

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.

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.

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.
摘要:
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.

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.
摘要:
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.
摘要:
An embodiment of the present invention provides a method of improving subcarrier permutation to achieve high frequency diversity of OFDMA systems in wireless networks, comprising introducing different tone selections for different symbols, such that if a channel has only a few tones in each symbol of a resource unit it can still have sufficient frequency diversity.
