Abstract
Methods, systems, and devices for spectral sharing wireless systems, wherein multiple user devices share time and frequency resources for uplink and/or downlink transmissions, are described. One example method includes transmitting transmission symbols from the network station to at least one user device by processing through a first precoder and a pre-compensation stage, wherein the pre-compensation stage is selected to have the transmission symbols receivable at the at least one user device to appear as if the transmission symbols are processed by a second precoder different from the first precoder.
Claims20
A method of wireless communication, comprising:
- determining, by a first wireless device, a second wireless device specific first precoder used for precoding transmissions, wherein the first precoder is determined to match a second precoder at a specific angular sector, and wherein the first precoder is determined based on channel measurements of transmissions from the second wireless device to the first wireless device;
- and
- performing a transmission from the first wireless device to the second wireless device using the first precoder for precoding the transmission.
An apparatus for wireless communication, implemented at a first wireless device, the apparatus comprising:
- one or more processors configured to:
- determine a second wireless device specific first precoder used for precoding transmissions, wherein the first precoder is determined to match a second precoder at a specific angular sector, and wherein the first precoder is determined based on channel measurements of transmissions from the second wireless device to the first wireless device;
- and
- a transceiver configured to:
- perform a transmission from the first wireless device to the second wireless device using the first precoder for precoding the transmission.
