Abstract
Methods and systems are disclosed for concurrent transmission of resource blocks allocated to a mobile device for transmission in uplink communication channels. In particular implementations, a mobile device may tune local oscillators and/or apply filtering of radio frequency transmission to reduce or mitigate intermodulation distortion potentially affecting one or more radio frequency receiving functions.
Claims26
A method, at a mobile device, comprising:
- scheduling transmission of one or more first allocated resource blocks in a first carrier of a first uplink communication channel;
- scheduling transmission of one or more second allocated resource blocks in a second carrier of a second uplink communication channel, at least a portion of the one or more second allocated resource blocks to be transmitted concurrently with transmission of at least a portion of the one or more first allocated resource blocks;
- in response to a determination that concurrent transmission in the first carrier and the second carrier likely interferes with a radio frequency (RF) receiving function:
- tuning a first oscillator for transmission of the one or more first allocated resource blocks to a first frequency within the one or more first allocated resource blocks;
- and
- tuning a second oscillator for transmission of the one or more second allocated resource blocks to a second frequency within the one or more second allocated resource blocks;
- and
- adjusting an uplink transmission bandwidth size and location to limit uplink transmissions, from the mobile device, to frequencies above a minimum frequency of the one or more first allocated resource blocks and below a maximum frequency of the one or more second allocated resource blocks.
5 more elements
A mobile device, comprising:
- a transmitter for transmitting messages in uplink communication channels;
- and
- one or more processors configured to:
- schedule transmission of one or more first allocated resource blocks through the transmitter in a first carrier of a first uplink communication channel;
- schedule transmission of one or more second allocated resource blocks through the transmitter in a second carrier of a second uplink communication channel, at least a portion of the one or more second allocated resource blocks to be transmitted concurrently with transmission of at least a portion of the one or more first allocated first resource blocks;
- in response to a determination that concurrent transmission in the first carrier and the second carrier likely interferes with a radio frequency (RF) receiving function:
- tune a first oscillator at the transmitter for transmission of the one or more first allocated resource blocks to a first frequency within the one or more first allocated resource blocks;
- and
- tune a second oscillator at the transmitter for transmission of the one or more second allocated resource blocks to a second frequency within the one or more second allocated resource blocks;
- and
- adjust an uplink transmission bandwidth size and location to limit uplink transmissions, from the mobile device, to frequencies above a minimum frequency of the one or more first allocated resource blocks and below a maximum frequency of the one or more second allocated resource blocks.
