Sony patents method to selectively switch frequencies during mobile data uploads
Sony has filed a patent application describing a method for wireless devices to decide when to change their transmission frequency during data uploads. The system checks specific conditions, such as the width of the frequency band, to determine if switching frequencies improves the connection for parts of the transmission.
In the filing’s own words
Methods, communications devices, infrastructure equipment, and circuitry are provided for determining whether to enable frequency hopping for a given portion of an uplink transmission. It is determined whether to perform frequency hopping for a plurality of portions of a uplink transmission to be transmitted in one or more uplink sub-bands of the one or more slots. The determination may be made, for example, based on a threshold sub-band width or a semi-static configuration. As such, frequency hopping may be performed only for a portion of an uplink transmission, or not at all.
What exactly they claim (claim 1)
1. A method for a communications device configured to transmit signals to and/or to receive signals from an infrastructure equipment of a wireless communications network via a wireless radio interface provided by the wireless communications network, the method comprising: identifying a sub-band format for one or more slots, the one or more slots having a plurality of sub-bands allocated to uplink and or downlink transmissions; determining whether to perform frequency hopping for a plurality of portions of an uplink transmission to be transmitted in one or more uplink sub-bands of the one or more slots; if it is determined that frequency hopping is to be performed for a respective portion of the uplink transmission, identifying a frequency hopping offset and performing frequency hopping for the uplink transmission based on the frequency hopping offset; and if it is determined that hopping is not to be performed for the respective portion of the uplink transmission, transmitting the respective portion of the uplink transmission using a set of resource blocks for the uplink transmission.
