Abstract
According to some embodiments, a method performed by a network node for communicating using time division duplexing (TDD) on a first radio access technology (RAT) carrier located within a frequency band of a second RAT comprises transmitting a first communication on the first RAT carrier to a first wireless device. A carrier center frequency of the first RAT carrier aligns with a middle of a resource block (RB) of the second RAT. In particular embodiments, the location of the center carrier frequency of the first RAT satisfies raster requirements of the first RAT.

A method performed by a network node for communicating using time division duplexing, TDD, on a first radio access technology, RAT, carrier located within a frequency band of a second RAT, the method comprising:
- transmitting a first communication on the first RAT carrier to a first wireless device, wherein a carrier center frequency of the first RAT carrier aligns with a middle of a resource block, RB, of the second RAT, and wherein the first RAT uses a 100 kHz based channel raster and the second RAT uses a subcarrier spacing, SCS, based channel raster.
A network node operable to communicate using time division duplexing, TDD, on a first radio access technology, RAT, carrier located within a frequency band of a second RAT, the network node comprising processing circuitry operable to:
- transmit a first communication on the first RAT carrier to a first wireless device, wherein a carrier center frequency of the first RAT carrier aligns with a middle of a resource block, RB, of the second RAT, and wherein the first RAT uses a 100 kHz based channel raster and the second RAT uses a subcarrier spacing, SCS, based channel raster.
A method performed by a wireless device for communicating using time division duplexing, TDD, on a first radio access technology, RAT, carrier located within a frequency band of a second RAT, the method comprising:
- receiving a first communication on the first RAT carrier, wherein a carrier center frequency of the first RAT carrier aligns with a middle of a resource block, RB, of the second RAT, and wherein the first RAT uses a 100 kHz based channel raster and the second RAT uses a subcarrier spacing, SCS, based channel raster.
A wireless device operable to communicate using time division duplexing, TDD, on a first radio access technology, RAT, carrier located within a frequency band of a second RAT, the wireless device comprising processing circuitry (120) operable to:
- receive a first communication on the first RAT carrier, wherein a carrier center frequency of the first RAT carrier aligns with a middle of a resource block, RB, of the second RAT, and wherein the first RAT uses a 100 kHz based channel raster and the second RAT uses a subcarrier spacing, SCS, based channel raster.
