A system uses signals received from actual user equipment (UE) to build in real time a reception pattern for base stations in a cellular communication system. Each UE is assigned a unique tone to broadcast so that a controller can analyze radio coverage by analyzing which base stations received signals from each UE in a coverage area. Cellular base stations necessarily have overlapping coverage and are assigned unique channel access values to avoid repeating values from overlapping cell sites. As overlaps change in real time, in response to live events, traffic jams, site outages, and new sites, signals received from UEs in the coverage area provide a real time view of system coverage. This allows better allocation of channel access values than prior art historical performance indicators using base station and controller call errors.

A method for receiving multicast service data is provided. The method includes the following. A terminal device transmits first indication information to a network device, where the first indication information indicates a target multicast service. The terminal device receives at least one downlink control information (DCI) transmitted by the network device, where the at least one DCI is used for scheduling the target multicast service. The terminal device restarts a bandwidth part (BWP) inactivity timer when the terminal device receives on a first BWP, according to the at least one DCI, data of the target multicast service transmitted by the network device.

A method for multicast communication. The method which may be performed by a terminal device comprises receiving a downlink control channel from a network node. The downlink control channel may be associated with a traffic of the terminal device. The method further comprises determining an uplink resource to transmit feedback for the traffic to the network node, according to the association between the downlink control channel and the traffic. A hybrid automatic repeat request feedback may be implemented efficiently and flexibly for different traffic such as multicast and unicast traffic.

A repeater node of a telecommunications network wirelessly communicates with a parent node and another node. The repeater node comprises receiver circuitry, processor circuitry, and transmitter circuitry. The receiver circuitry is configured to receive a frame of information from the parent node. The processor circuitry is configured to include a customized control signal in the frame of information received from the parent node. The customized control signal is customized for the repeater node. The transmitter circuitry is configured to transmit the frame of information which includes the customized control signal to the other node which may be a wireless terminal.

A Multicast-Broadcast over a Single Frequency Network (MBSFN) message may be multicasted to a cluster of network elements. Using multicasting or unicasting based on a number of unacknowledged network elements of the cluster of network elements, the MBSFN message may be retransmitted to unacknowledged network elements in the cluster of network elements, subsequent to a time period to receive an acknowledgement message from a first and a second network element.

The transmission of a reference signal, such as a CSI-RS, is enabled while maintaining a power saving effect when performing inter-cell cooperative transmission/reception or the like in a plurality of cells. In order to realize inter-cell cooperative transmission/reception, a CSI-RS which is used for estimating the state of a spatial propagation path of a communication line is generated by a CSI-RS generation unit, and the CSI-RS is disposed in a predetermined subframe by a disposition unit and transmitted. At this time, when a frame has ten subframes #0 to #9, the CSI-RS is disposed in the subframes #4 and #9, which are subframes excluding the subframes #0 and #5 incapable of transmitting a CSI-RS and are subframes other than subframes capable of acting as MBSFN subframes when discontinuous communication (Extended Cell DTX) is performed so as to achieve power saving, and transmitted.
