Abstract
A remote radio head (RRH) of a distributed radio access network (RAN) is equipped with a co-located user equipment (UE). The UE can be a chipset integrated into the RRH, which is connected to other parts of the RAN via a fronthaul network. The UE can be used to relay information, such as management information to and/or from the RRH. Timing information obtained by the UE can be provided to the RRH and used as an indication of fronthaul latency. The RRH can then adjust its operation in response to the indication of fronthaul latency.
Claims17
An infrastructure apparatus for a distributed radio access network (RAN), comprising:
- a remote radio head (RRH) including:
- a network interface configured to operatively couple the RRH to one or more other components of the distributed RAN via a fronthaul communication network;
- and
- a radiofrequency (RF) transmitter and receiver configured to communicatively couple to a User Equipment (UE) over a wireless link using a wireless communication protocol;
- and
- a user equipment component (RRH-UE) co-located with the RRH, the RRH-UE configured to communicatively couple to the RF transmitter to receive using the wireless communication protocol, from the RRH, parameters related to a physical air interface of the wireless link, and to communicatively couple to the RRH using an internal interface to interoperate with the RRH and to provide the received parameters for facilitating RRH operation.
A distributed radio access network (RAN) comprising:
- a baseband unit (BBU);
- a remote radio head (RRH) at a location separate from the BBB, the RRH comprising:
- a network interface configured to operatively couple the RRH to the BBU via a fronthaul communication network;
- a radiofrequency (RF) transmitter and receiver configured to communicatively couple to a User Equipment (UE) over a wireless link using a wireless communication protocol;
- and
- a user equipment component (RRH-UE) co-located with the RRH, the RRH-UE configured to communicatively couple to the RF transmitter to receive using the wireless communication protocol, from the RRH, parameters related to a physical air interface of the wireless link, and to communicatively couple to the RRH using an internal interface to intemperate with the RRH and to provide the received parameters for facilitating RRH operation.
A method for operating a remote radio head (RRH) of a distributed radio access network (RAN), the method comprising:
- transmitting, by a base station (BS) comprising the RRH, over a wireless link using a wireless communication protocol supported by the distributed RAN, to a user equipment component (RRH-UE) co-located with the RRH, parameters related to a physical air interface of the wireless link;
- receiving, by the RRH, using an internal interface, the parameters from the RRH-UE;
- and
- adjusting operation of the RRH based on the received parameters, the wireless communication protocol also used for communicating with a plurality of user equipment (UE) devices served by the RRH.
