Techniques To Reduce Interference Between Uplink Channel and Adjacent Channel TDD Transmissions In Wireless Networks

A method of reducing interference with an adjacent channel, the method comprising:

• determining, by a base station associated with a first cell, an uplink/downlink configuration for one or more slots of an adjacent channel of a neighbor cell, the adjacent channel being adjacent in frequency or frequency band to a first channel used by the base station for uplink transmissions for the first cell;
• receiving, by the base station from a user device associated with the first cell, a measurement report indicating whether or not the user device can detect uplink signals from one or more neighbor user devices associated with the neighbor cell on one or more uplink slots of the adjacent channel of the neighbor cell;
• determining, by the base station based on the uplink/downlink configuration determined by the base station, slots of the adjacent channel where there are no downlink signals transmitted for the adjacent channel;
• scheduling, by the base station, the user device for uplink transmission on resources of the first channel during the one or more slots of the adjacent channel where there are no downlink signals transmitted for the adjacent channel of the neighbor cell;
• and
• scheduling, by the base station, the user device for uplink transmission on resources of the first channel during one or more downlink slots of the adjacent channel if the measurement report from the user device indicates that the user device cannot detect uplink signals from one or more neighbor user devices associated with the neighbor cell on one or more uplink slots of the adjacent channel of the neighbor cell.

A method of reducing interference with an adjacent channel, the method comprising:

• receiving, by a user device associated with a first cell from a base station associated with the first cell, information indicating the uplink/downlink configuration for one or more slots of an adjacent channel, the adjacent channel being adjacent in frequency or frequency band to a first channel used by the base station for uplink transmissions for the first cell;
• determining, by the user device based on the received uplink/downlink configuration for one or more slots of the adjacent channel and based on an attempt by the user device to detect and measure signals on one or more uplink slots of the adjacent channel, whether or not the user device can detect uplink signals from one or more neighbor user devices associated with the neighbor cell on one or more uplink slots of the adjacent channel of the neighbor cell;
• receiving, by the user device from the base station, either an uplink grant or an uplink configuration for a semi-static resource allocation, indicating resources of the first channel for uplink transmission during one or more downlink slots and during one or more uplink slots of the adjacent channel of the neighbor cell if the user device cannot detect uplink signals from one or more neighbor user devices associated with the neighbor cell on one or more uplink slots of the adjacent channel of the neighbor cell;
• and
• sending, by the user device associated with the first cell to the base station, a measurement report indicating whether or not the user device can detect uplink signals from one or more neighbor user devices associated with the neighbor cell on one or more uplink slots of the adjacent channel of the neighbor cell.
