Sony patents method to cut delay in wireless network connections
Sony describes a technique for wireless devices to connect to a network base station with less delay. The system uses specific time slots for sending a signal and data, with a fixed gap between them to optimize the process.
In the filing’s own words
At least one information block is received from a base station of a network, the at least one information block indicating one or more first resources ( 511) and one or more second resources ( 512) for a random-access procedure, the second resources ( 512) being offset from the first resources ( 511) by a time gap ( 550). A preamble ( 2011) of the random-access procedure is transmitted to the base station using the one or more first resources ( 511) and data ( 2012) is transmitted to the base station using the one or more second resources ( 512).
What exactly they claim (claim 1)
1. A device comprising control circuitry configured to: receive at least one of a master information block or a system information block from a network node of a network, the at least one of the master information block or the system information block indicating resources for a random-access procedure including one or more first resources for a random-access preamble and one or more second resources for data, the at least one of the master information block or the system information block further indicating a time gap between the one or more first resources and the one or more second resources, after receiving the at least one of the master information block or the system information block: select a preamble from a plurality of candidate preambles depending on the at least one of the master information block or the system information block, select the one or more second resources depending on the selected preamble and the time gap, transmit the preamble for the random-access procedure to the network node using the one or more first resources, determine a modulation and/or a coding scheme of data depending on the at least one of the master information block or the system information block, and transmit data to the network node using the one or more second resources and the modulation and/or coding scheme determined.
