摘要： Embodiments are provided to support device-to-device (D2D) communications in a time-division duplexing (TDD) communications system, and ensure that D2D discovery signals are transmitted by user devices on an uplink subframe when there is a TDD frame configuration change. In an embodiment, a user device receives form the network a TDD frame configuration selected from a set of available TDD frame configurations according to the TDD configuration. The device further receives a D2D discovery configuration for a discovery time interval. The user device then allocates a transmission resource a D2D discovery signal within the discovery time interval according to the D2D discovery configuration. The user device is also configured to receive from another device a second D2D discovery signal during the discovery time interval in accordance with the TDD configuration and the D2D discovery configuration.

摘要： The disclosure relates to technology for a base station to signal user equipment to monitor a narrowband control channel in a wideband system. The base station sends a configuration signaling to configure the user equipment including a designation of subframe(s). The base station then determines whether to signal the user equipment to monitor the subframe(s) using one of a narrowband bandwidth and a system bandwidth. In response to the base station signaling the user equipment to monitor the narrowband bandwidth, the base station communicates with the user equipment using the narrowband bandwidth. In response to the base station signaling the user equipment to monitor the system bandwidth, the base station sends a probe message within the narrowband bandwidth to the user equipment, where the probe message signals to the user equipment to begin monitoring the system bandwidth and to communicate with the user equipment using the system bandwidth.
