1. A distributed antenna system comprising:
- a master unit having first circuitry;
a first remote unit having second circuitry and communicatively coupled to the master unit;
a second remote unit having third circuitry and communicatively coupled to the master unit;
wherein the first remote unit is configured to;
receive downlink RF signals from a base station; and
provide downlink signals to the master unit; and
wherein the master unit is configured to;
transmit the downlink signals received from the first remote unit to the second remote unit; and
instruct the first remote unit to establish a different communication link with the base station in response to detecting a malfunction with respect to an additional communication link between the master unit and an additional base station.

Abstract
A remote unit of a distributed antenna system includes: a transceiver configured to communicate RF signals between a master unit of the distributed antenna system and a terminal device, and receive downlink RF signals from a base station; and signal processing circuitry configured to provide downlink signals to the master unit. The remote unit receives instructions from a host unit of the distributed antenna system to establish a communication link with the base station in response to detecting a malfunction with respect to an additional communication link between the master unit and an additional base station.

16. A distributed antenna system for providing device-to-device communication, the distributed antenna system comprising:
-
a first remote unit having first circuitry, the first remote unit configured to; receive at least one signal from a first base station; when the at least one signal is received at a signal level that exceeds a threshold signal level, switch to a receive mode for receiving signals from the first base station; when the at least one additional signal is received at an additional signal level that does not exceed the threshold signal level, switch to a transmit mode for transmitting signals to a terminal device; a second remote unit having second circuitry, the second remote unit configured to transmit the at least one signal to the terminal device; and a master unit having third circuitry and communicatively coupled to the first and second remote units, the master unit configured to receive the at least one signal from the first remote unit and provide the at least one signal to the second remote unit for transmission to the terminal device. - View Dependent Claims (17, 18, 19, 20)
