Abstract: For a UE in a wireless network and able to communicate via sidelink communications with other UE(s), the UE determines whether a specific condition exists indicating the UE has limited availability of CG resources used to communicate for the sidelink communications. The UE sends, using the sidelink communications, a message indicating the limited availability of the CG resources toward the other UE(s). Another UE receives the message indicating a limited availability of CG resources for the UE, and prepares an application in the other UE for a less sensitive mode of operation having less QoS than a mode having a normal QoS. A base station can configure the UE with the CG resources and provide a set of parameters to the UE to be used to form the message for the user equipment to transmit to the other UE(s) using sidelink communications.

Abstract: In a method for transmitting data through a Massive MIMO backhaul system, a central node of the MIMO backhaul system transmits, to a small cell repeater terminal on the downlink, a downlink pilot signal carrying a set of pilot sequences that are mutually orthogonal in the frequency domain. Each pilot sequence in the set of pilot sequences corresponds to an antenna of an antenna array at the central node. The central node receives an uplink pilot signal carrying the set of pilot sequences transmitted by the small cell repeater terminal on the uplink, where the received uplink pilot signal is a frequency converted retransmission of the downlink pilot signal. The central node estimates at least one of an uplink channel and a downlink channel between the central node and the small cell repeater terminal based on the set of pilot sequences and the received uplink pilot signal.
