Repeater device for 5G new radio communication

A repeater device for New Radio (NR) communication, comprising:

• a baseband processor configured to:
• establish a communication link with a base station, wherein the communication link established with the base station is a side link;
• receive, from the base station, control information as a modulated pulse through a control channel, wherein the control information is side control information and the control channel is a side control channel;
• decode the received control information which includes primary synchronization signals (PSS) that indicate a timing boundary of a 5G NR radio frame;
• align, based on the decoded control information, a timing reference of the repeater device with that of an NR cell frame for one of an uplink or a downlink time division duplex (TDD) switching;
• select a first operating mode from a plurality of operating modes of the repeater device based on at least one of a number of a plurality of user equipment (UEs), a distance of the plurality of UEs from the base station, or a spatial distribution of the plurality of UEs, wherein
• the plurality of operating modes includes a beam widening mode, a switching multi-beam mode, a concurrent multi-beam mode, and a static beam mode, and an operating mode that includes one or more specified combination of the static beam mode, the beam widening mode, the switching multi-beam mode, and the concurrent multi-beam mode;
• receive feedback from the plurality of UEs, wherein the feedback indicates one of:
• which type of beam is suitable for the plurality of UEs, or
• one of whether to cover one of the plurality of UEs by an individual beam, a group of UEs from the plurality of UEs by a single beam, or the group of UEs by multiple concurrent beams;
• select and form a plurality of donor beams of Radio Frequency (RF) signals at a donor side of the repeater device and a plurality of service beams of RF signals at a service side of the repeater device, based on the decoded control information, the aligned timing reference with that of the NR cell frame for one of the uplink or the downlink TDD switching for communication in an NR frequency band, and the first operating mode, wherein
• the selection and formation of the plurality of service beams of RF signals is further based on the received feedback;
• form the plurality of donor beams of RF signals, concurrently towards one of a plurality of target base stations or a plurality of repeater devices different from the repeater device, based on the first operation mode, a plurality of requested donor beam identifiers, and a plurality of pre-stored donor beam identifiers, wherein the plurality of requested donor beam identifiers is shared by at least one of the plurality of target base stations through the control channel to reach the repeater device;
• track a trajectory of motion of each of the plurality of UEs to be within a coverage area of the one or more service beams of RF signals without constantly tracking locations of each of the plurality of UEs;
• and
• dynamically adjust the coverage area of the plurality of service beams of RF signals based on the trajectory of motion of the plurality of UEs.
