Abstract
Methods, systems, and devices for wireless communication provide for split symbol control by varying tone spacing and symbol duration for control channels in a subframe. The control symbols may be transmitted at various locations within the subframe and may be transmitted to different mobile devices. In some examples, multiple control symbols may be transmitted in a subframe to multiple mobile devices depending on the capabilities of each of the multiple mobile devices.
Claims30
A method for wireless communication, comprising:
- identifying a first number of control symbols for a subframe based at least in part on a first tone spacing;
- determining locations within the subframe for each of the first number of control symbols;
- and
- transmitting the first number of control symbols in the subframe in accordance with the determined locations.
A method for wireless communication, comprising:
- transmitting, in accordance to a first tone spacing, a first control symbol at a first control start time within a first subframe, and a first data symbol at a first data start time within the first subframe;
- and
- transmitting, in accordance to a second tone spacing, a second control symbol at a second control start time within a second subframe, and a second data symbol at a second data start time within the second subframe, the second control start time being the same as the first control start time and the second data start time being different from the first data start time.
A method for wireless communication, comprising:
- receiving, in accordance to a first tone spacing, a first control symbol at a first control start time within a first subframe, and a first data symbol at a first data start time within the first subframe;
- and
- receiving, in accordance to a second tone spacing, a second control symbol at a second control start time within a second subframe, and a second data symbol at a second data start time within the second subframe, the second control start time being the same as the first control start time and the second data start time being different from the first data start time.
An apparatus for wireless communication, in a system comprising:
- a processor;
- memory in electronic communication with the processor;
- and
- instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
- identify a first number of control symbols for a subframe based at least in part on a first tone spacing;
- determine locations within the subframe for each of the first number of control symbols;
- and
- transmit the first number of control symbols in the subframe in accordance with the determined locations.
