20120083302 | METHOD AND APPARATUS FOR FAST OTHER SECTOR INTERFERENCE (OSI) ADJUSTMENT - Systems and methods that facilitate management of interference and communication resources are provided. A differential approach is devised in which other-sector interference (OSI) and communication resources are managed by adjusting an offset (delta) value associated with the resources in response to receiving an indication of other-sector interference. An OSI indication can be issued based on a short and a long time scale, and effective interference metrics over time-frequency resources. The adjusted delta value is communicated to a serving access point, which reassigns communication resources in order to mitigate other-sector interference. | 04-05-2012 |
20120252523 | SERVING SECTOR INTERFERENCE BROADCAST AND CORRESPONDING RL TRAFFIC POWER CONTROL - Systems and methodologies are described that facilitate broadcasting an interference level and adjusting transmit power corresponding to a reverse link in accordance with the interference level. An interference indication can be broadcasted on a broadcast channel in a wireless communication system. In response to the broadcast, mobile devices can adjust transmit power on the reverse link based upon considerations of the interference level. Further, mobile devices can evaluate an initial set point of a transmit power level during periods of inactivity. | 10-04-2012 |
20130237262 | METHOD AND APPARATUS FOR ADJUSTMENTS FOR DELTA-BASED POWER CONTROL IN WIRELESS COMMUNICATION SYSTEMS - Systems and methodologies are described that provide techniques for performing adjustments for delta-based power control and interference management in a wireless communication system. A terminal can utilize one or more delta-based power control techniques described herein upon engaging in a reverse link transmission after a predetermined period of silence or after receiving indications of interference from neighboring access points. A delta value can be computed through open-loop projection, based on which transmission resources such as bandwidth and/or transmit power can be increased or decreased to manage interference caused by the terminal. A delta value, other feedback from the terminal, and/or indications of interference caused by the terminal can also be communicated as feedback to a serving access point to allow the access point to assign transmission resources for the terminal. | 09-12-2013 |
20140241337 | METHOD AND APPARATUS FOR GENERATION OF BALANCED WEIGHT PREAMBLE SEQUENCES - Various aspects of an approach for generating a large number of balanced weight sequences such as balanced Hamming weight preamble sequences are described herein. The approach provides for the generation of balanced weigh sequences that need to satisfy requirements such as minimal cross-correlation with delayed versions of itself and other sequences in the allowed set. The approach includes creating a set of symbol groups that include balanced properties from which a sequence may be generated by selecting therefrom. | 08-28-2014 |
20140269666 | METHOD AND APPARATUS FOR EFFICIENT SIGNALING OF COMMUNICATION MODE AND DELIMITER INFORMATION - Various aspects for efficient preamble selection and configuration based on wireless communication parameters to provide a reduction of preamble overhead by generating and transmitting packet preambles based on a data rate that is to be used for communication between wireless devices are disclosed herein. In one aspect of the disclosed approach, a preamble sequence is selected from a set of preamble sequences, wherein each preamble sequence is associated with at least one communication mode and the selected preamble sequence is configured to signal a respective communication mode. A preamble structure is generated based on the selected preamble sequences and then transmitted to a receiver. A period of silence may be associated with the communication mode to be communicated, and the transmitter may be configured to not transmit the preamble structure before the period of silence expires. | 09-18-2014 |
20140269667 | METHOD AND APPARATUS FOR DYNAMIC CONFIGURATION OF PACKET PREAMBLES FOR SYNCHRONIZATION-BASED TRANSMISSIONS - Various aspects of the disclosed approach described herein allows a reduction of preamble overhead by tailoring transmitted packet preambles based on an expected level of clock-related offset between a transmitter and a receiver for a pair of communicating nodes. An estimate may be maintained at the transmitter of maximum time and frequency offsets between the transmitter and the receiver. The estimate may then be utilized to create a customized preamble sequence for generating the packet preamble. The estimate may also be utilized to select a particular modulation technique for the packet preamble. | 09-18-2014 |
20140301298 | METHODS AND APPARATUS FOR TRANSMISSION RESTRICTION AND EFFICIENT SIGNALING - Certain aspects of the present disclosure relate to methods and apparatus for transmission restriction and efficient signaling. A base station (BS) may determine information regarding a restricted set of system parameters used for transmission from at least one of the serving BS or one or more potentially interfering BSs and signal the information to a user equipment (UE). According to certain aspects, a UE may receive the signaling of information regarding the restricted set of system parameters used for transmission from at least one of the serving BS or the one or more potentially interfering BSs and use the information to cancel interference by transmissions from the one or more potentially interfering BSs or serving BS. | 10-09-2014 |
20150180622 | MIXED NUMEROLOGY OFDM DESIGN - Methods, systems, and devices are described for hierarchical communications and low latency support within a wireless communications system. An eNB and/or a UE may be configured to operate within the wireless communications system which is at least partially defined through a first layer with first layer transmissions having a first subframe type and a second layer with second layer transmissions having a second subframe type. The first subframe type may have a first round trip time (RTT) between transmission and acknowledgment of receipt of the transmission, and the second layer may have a second RTT that is less than the first RTT. Subframes of the first subframe type may be multiplexed with subframes of the second subframe type, such as through time division multiplexing. In some examples symbols of different duration may be multiplexed such that they different symbol durations coexist. | 06-25-2015 |
