摘要:
Embodiments of the present disclosure describe closed loop scheduled peak-to-average power (PAPR) reduction systems and methods to facilitate desired PAPR reduction. Other embodiments describe weighted tone reservation (WTR) methods and systems for PAPR reduction. Still other embodiments may be described and claimed.
摘要:
Embodiments of a base station and methods for allocating uplink bandwidth using SDMA are generally described herein. In some embodiments, uplink bandwidth request messages are received on a bandwidth request contention channel from one or more subscriber stations. The uplink bandwidth request messages are generated by the subscriber stations by modulating pilot subcarriers of a randomly selected disjoint pilot pattern with a randomly selected orthogonal sequence. The base station allocates uplink bandwidth to the subscriber stations when the uplink bandwidth request messages are successfully detected and decoded. The base station uses an SDMA technique to determine channel responses based on the orthogonal sequences to detect and decode the uplink bandwidth request messages.
摘要:
Embodiments provide techniques for power control. For instance, a method exchanges one or more transmissions with a remote device in accordance with a retransmission protocol. In addition, a power control message is exchanged with the remote device through at least one of the one or more transmissions. Thus, closed loop power control may be performed through retransmission protocol communications.
摘要:
Methods and apparatuses for scheduling transmissions between a base station and multiple user stations in a broadband wireless access network may include a subscriber station generating a bandwidth request which includes one of a limited number of available and predefined preamble sequences and a data portion identifying the resources requested. The subscriber station randomly selects a contention slot in a wireless channel, allocated by the base station, for sending a bandwidth request. The receiving base station is able to detect the preamble sequence of bandwidth requests and differentiate between subscribers even when bandwidth requests of two or more subscribers may collide by virtue of selecting the same contention slot. In this manner, latency and overhead of bandwidth requests may be improved. Additional variants and embodiments are also disclosed.
摘要:
An embodiment of the present invention provides a method, comprising broadcasting base station (BS) channel allocation methods and supported interference mitigation techniques in a whole cell by the base station and reporting classification information by mobile stations (MSs) within the cell to said base station about their preferred interference mitigation (IM) techniques.

Device, system, and method of channel quality indication. In some demonstrative embodiments a method may include, for example, calculating a plurality of channel-quality-indicator values corresponding to a plurality of sub-channels associated with a mobile communication device; and transmitting a channel-quality-indicator message from the mobile communication device to a base station, the channel-quality-indicator message including only first and second channel-quality-indicator values of the plurality of channel-quality-indicator values corresponding to first and second sub-channels of the plurality of sub-channels. Other embodiments are described and claimed.
摘要:
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.

Embodiments of wireless adaptive control message apparatus, systems, and methods are described generally herein. Other embodiments may be described and claimed.
摘要:
Systems, methods, and devices for device-to-device (D2D) distributed scheduling are disclosed herein. User equipment (UE) is configured to measure a received power level for a reference signal received from a target UE and measure received power levels for reference signals received from one or more non-target UEs. The UE is configured to generate a resource usage map for the target UE and the one or more non-target UEs. The UE is configured to determine a priority, with respect to the target UE, for each resource element group based on the resource usage map and an anticipated signal-to-interference ratio (SIR). The UE is configured to transmit data to the target UE during one or more resource element groups with the highest priorities for the target UE.
摘要:
Embodiments described herein relate generally to a user equipment (“UE”) that is to transmit and receive signals associated with synchronization. The UE may be receive signals associated with synchronization from a plurality of synchronization sources, such as an evolved Node B (“eNB”), a global navigation satellite system (“GNSS”), or another UE. The UE may synchronize to a signal received from a synchronization source based on a priority associated with that synchronization source and/or signal. However, if the UE does not receive any signals associated with synchronization, the UE may generate and transmit a signal that indicates a request for synchronization.
