Abstract:
A network protocol method (300), access point device (600) and peripheral devices (700, 800) provide an efficient centrally coordinated peer-to-peer wireless communications network wherein the access point device: (1) broadcasts a block assignment that specifies a wireless source peripheral device and a wireless destination peripheral device; (2) receives, from the wireless destination peripheral device, sequence information; (3) determines whether the sequence information represents one of: a negative acknowledgment and a positive acknowledgment with a sequence number; (4) forwards an acknowledgment to the wireless source peripheral based on the sequence information, and repeats steps (1)-(4) until N blocks of data, N a predetermined integer, have been transferred from the wireless source peripheral to the wireless destination peripheral.
Abstract:
A method (300), system (400), base station (500), head-end unit (600), and subscriber unit (700) provide for efficient resource management in a communication system or group of communication systems supporting a plurality of communication units, where different communication units may have varying resource size requirements. The method includes the steps of: determining a resource size requirement of a communication unit of the plurality of communication units, determining a hierarchical level within the hierarchy that the communication unit is to be assigned to based on the resource size requirement of the communication unit, and assigning the communication unit to an available resource slot in the hierarchical level in accordance with a predetermined hierarchical management scheme that maximizes a total number of remaining available slots in the hierarchy.
Abstract:
A wireless communications system base station (101), upon receiving (202) from a mobile station (102) a wireless transmission that comprises a suggested transmitter-receiver configuration, can respond (in appropriate instances) by automatically transmitting (203) to the mobile station a wireless transmission comprising an indication to use instead a default transmitter-receiver configuration. By one approach, the latter action can be based, at least in part, upon a determination regarding reliability (301) of that suggested transmitter-receiver configuration (which might comprise, for example, a direct or indirect measure of quality of the channel by the default transmitter-receiver configuration was received) to provide a corresponding reliability assessment. The latter can then be used (302) to determine whether to use this suggested transmitter-receiver configuration for a subsequent communication with the mobile station.
Abstract:
System (100) for generating syndrome (222) usable in decoder (130) includes reducer (340) and converter (330). Reducer (340) employs information to generate representation (342). Converter (330) generates, with employment of representation (342), syndrome (222).
Abstract:
The invention provides a method for operating a hybrid automatic repeat request communication system wherein it is determined whether a receiver can process a data packet, and a self-decode request associated with the data packet is sent based on the determination.
Abstract:
System includes decoder. Decoder performs a portion of an intermediate Chase iteration, of a series of Chase iterations for decoding input data, to obtain a successful hard-decision decoding result for input data. Decoder determines that the successful hard-decision decoding result comprises overall Chase decoding result, for the series of Chase iterations, with employment of reliability information for at least one location of input data and without employment of information that specifies, for input data, error location within input data. The intermediate Chase iteration and a Chase iteration comprise consecutive Chase iterations having only one value difference between respective code patterns thereof. Decoder skips at least one intermediate Chase iteration to proceed to the intermediate Chase iteration that obtains the successful hard-decision decoding result.
Abstract:
A first group of bits (100, 102, 106), e.g., header symbols/bits, are interleaved to form a first group of interleaved bits. A second group of bits (104), e.g., data symbols/bits, are interleaved to form a second group of interleaved bits. The first and second groups of interleaved bits are mapped to an information burst (114). The first and second groups of interleaved bits may be mapped to the information burst relative to a group of known symbols (116) forming a training sequence. A disadvantaged bit location, i.e., a bit location within the mapping having a relative high probability of incurring a bit error, is identified and an advantaged bit location, i.e., a bit location within the mapping having a relatively low probability of incurring a bit error, is identified. A first group bit from the first group of interleaved bits mapped to the disadvantaged bit location is remapped to the advantaged bit location while a second group bit from the second group of interleaved bits mapped to the advantaged bit location is remapped to the disadvantaged bit location.
Abstract:
A method (300), system (400), base station (500), head-end unit (600), and subscriber unit (700) provide for efficient resource hopping in a communication system or group of communication systems supporting a plurality of communication units, where different communication units may have varying resource size requirements. The method includes the steps of: assigning a communication unit of the plurality of communication units to a resource slot within a level of a plurality of levels of a hierarchical representation of a resource region, assigning an available resource hopping pattern and associated initial resource location within the resource slot to the communication unit, and hopping, by the communication unit in accordance with a predetermined hierarchical resource hopping scheme.
