  • Patent number: 8077690
    Abstract: A method for assigning resources to frequency selective (FS) and frequency non-selective (FNS) users, for example, in an orthogonal frequency-division multiplexing (OFDM) wireless communication system, including assigning a first frequency resource to at least one FS user during a time interval, wherein the first frequency resource includes at least two near contiguous sub-carriers, and assigning a second frequency resource to at least one FNS user during the same time interval, the second frequency resource includes for each FNS user at least two non-contiguous sub-carriers, wherein the first and second frequency resources are part of a common frequency channel.

  • Patent number: 6359898
    Abstract: The method for transmitting a communication signal comprising a plurality of units of information includes transmitting the plurality of units of information via a predetermined number of channel resources; determining a number of the plurality of units remaining in at least a portion of the communication signal; based on the predetermined number of channel resources, adjusting the number of the plurality of units remaining to produce an adjusted number of units remaining; and transmitting the adjusted number of units remaining to the wireless communication system.

  • Patent number: 6088337
    Abstract: A method, access point device and a plurality of peripheral devices provide for controlling a space diversity switch in a time division duplex system. The method includes: inputting data to a peripheral; generating a CRC.sub.1 in a peripheral; transmitting the data and the CRC.sub.1 ; receiving, by an access point device, the data with the CRC.sub.1 ; extracting CRC.sub.1 and generating CRC.sub.2 from received data; determining whether CRC.sub.1 and CRC.sub.2 are equal and where CRC.sub.1 and CRC.sub.2 are equal, failing to generate a repeat request; where CRC.sub.1 and CRC.sub.2 are unequal, generating a repeat request; determining whether a number of requests=N; where the number of requests.noteq.N, incrementing a counter and returning to receiving the data with the CRC.sub.1 ; and where the number of requests=N, resetting the counter, changing an antenna state and returning to receiving, by an access point device, the data with the CRC.sub.1.

  • Patent number: 6058106
    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.

  • Patent number: 5862452
    Abstract: A method, access point device and a perpherical device provide low complexity dynamic persistence for random access in a wireless communication system. The peripheral device includes: A) a block assignment receiver, for receiving a block assignment having a source address which contains a contention address and a persistence level and identifying the contention address and reading the persistence level; B) a random number generator, coupled to the block assignment receiver, for generating a random number based on the persistence level; and C) a persistence based transmitter, coupled to the random number generator, for transmitting a payload burst containing a resource request based on the random number and the persistence level.

  • Patent number: 5640396
    Abstract: A method of synchronizing a fixed access unit (16) into a time division multiple access (TDMA) system (10). The method includes the steps of receiving a first timing advance channel time slot (86) at the fixed access unit (16), sending a message advanced in time by an offset value over a second time slot (88), receiving an acknowledgment from the TDMA system (10) that the message was received, and advancing a subsequently transmitted communication based on the offset value.
