Abstract

A wireless device, a method, and a computer program product in a wireless device are provided in which a scheduling control signal is received in peer-to-peer resources. In addition, whether to yield a data transmission is determined based on the received scheduling control signal. Furthermore, the data transmission is sent to a base station on the peer-to-peer resources upon determining not to yield the data transmission. A base station, a method, and a computer program product in a base station are also provided in which a scheduling control signal is received in peer-to-peer resources. In addition, whether to yield a data transmission is determined based on the received scheduling control signal. Furthermore, the data transmission is sent to a wireless device on the peer-to-peer resources upon determining not to yield the data transmission.
