Method for avoiding collisions between open discovery and cellular resource
First Claim
1. A method comprising:
- receiving, by a user equipment from a communications controller, uplink or downlink scheduling information to transmit an uplink control signal on a physical uplink channel to the communications controller on a subframe designated for device-to-device (D2D) signaling by a D2D subframe configuration designating one or more subframes in which to transmit or receive one or more D2D discovery signals;
prioritizing, by the user equipment based on contents of the received uplink or downlink scheduling information, transmission of the uplink control signal on the subframe designated for D2D signaling by the D2D subframe configuration over a transmission or a reception of the one or more D2D discovery signals,the one or more D2D discovery signals comprising a Type 1 discovery signal or a Type 2 discovery signal, the Type 1 discovery signal for allocating discovery signal transmission resources on a non user equipment-specific basis, and the Type 2 discovery signal for allocating the discovery signal transmission resources on a per user equipment-specific basis; and
transmitting, by the user equipment, the uplink control signal on the subframe designated for D2D signaling by the D2D subframe configuration to the communications controller.

Abstract
A device is configured to perform a method of wireless communication in a wireless communication network. The method includes receiving, from a communications controller, a device-to-device (D2D) subframe configuration to communicate with one or more second wireless devices, the subframe configuration indicating one or more subframes in which to transmit a D2D signal or receive one or more D2D signals. The method also includes receiving, from the communications controller, scheduling information to transmit a first signal to the communications controller on a subframe indicated by the D2D subframe configuration. The method further includes prioritizing the transmission of the first signal over a transmission of the D2D signal or a reception of the one or more D2D signals, and transmitting the first signal.

9. A user equipment comprising:
-
at least one antenna configured to transmit and receive signals; and at least one processor coupled to the at least one antenna, and configured to; receive, from a communications controller, uplink or downlink scheduling information to transmit an uplink control signal on a physical uplink channel to the communications controller on a subframe designated for device-to-device (D2D) signaling by a D2D subframe configuration designating one or more subframes in which to transmit or receive one or more D2D discovery signals, wherein the one or more D2D discovery signals comprise a Type 1 discovery signal or a Type 2 discovery signal, the Type 1 discovery signal for allocating discovery signal transmission resources on a non user equipment-specific basis, and the Type 2 discovery signal for allocating the discovery signal transmission resources on a per user equipment-specific basis, prioritize, by the user equipment based on contents of the received uplink or downlink scheduling information, transmission of the uplink control signal on the subframe designated for D2D signaling by the D2D subframe configuration over a transmission or a reception of the one or more D2D discovery signals, and transmit the uplink control signal over the at least one antenna on the subframe designated for D2D signaling by the D2D subframe configuration to the communications controller. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A non-transitory computer readable medium embodying a computer program for a user equipment, the computer program comprising computer readable program code to:
-
receive, from a communications controller, uplink or downlink scheduling information to transmit an uplink control signal on a physical uplink channel to the communications controller on a subframe designated for device-to-device (D2D) signaling by a D2D subframe configuration designating one or more subframes in which to transmit or receive one or more D2D discovery signals, wherein the one or more D2D discovery signals comprise a Type 1 discovery signal or a Type 2 discovery signal, the Type 1 discovery signal for allocating discovery signal transmission resources on a non user equipment-specific basis, and the Type 2 discovery signal for allocating the discovery signal transmission resources on a per-user equipment-specific basis; prioritize, by the user equipment based on contents of the received uplink or downlink scheduling information, transmission of the uplink control signal on the subframe designated for D2D signaling by the D2D subframe configuration over a transmission or a reception of the one or more D2D discovery signals; and transmit the uplink control signal on the subframe designated for D2D signaling by the D2D subframe configuration to the communications controller. - View Dependent Claims (18, 19, 20, 21)
