Aspects are described for use in wireless communications. Nodes may provide wireless access to wireless devices in different coverage areas. The nodes may transmit messages having time interval allocation bitmaps that indicate reduced transmission power time intervals. The reduced transmission power time intervals may be different for different nodes.

Embodiments of the present disclosure provide a method in a base station for coordinating resources in a wireless communications system with carrier aggregation in which a first group of terminal devices is served by a primary cell and one or more secondary cells under control of the base station. The method comprises obtaining information indicating arrival of a second group of terminal devices at coverage of the base station. A speed of any terminal device of the second group is higher than a speed of any terminal device of the first group. The method also comprises releasing resources on at least one secondary cell of the one or more secondary cells and allocating the released resources to the second group of terminal devices.

A system includes a processor. The system also includes a memory connected to the processor, where the memory is configured to store executable instructions that, when executed by the processor, facilitate performance of operations, including: detecting an outage associated with devices of a cellular antenna, where the outage defines a cellular coverage hole; determining, in response to detecting the outage, one or more neighboring cellular antennas to the cellular antenna with the outage that are configured to provide coverage of the cellular coverage hole based upon a first criteria; determining for the neighboring cellular antennas satisfying the first criteria whether a second criteria is satisfied; and issuing an instruction, based on neighboring cellular antennas satisfying the second criteria, to up-tilt at least one of the one or more neighboring cellular antennas satisfying the second criteria.

An orthogonal frequency-division multiplexing (OFDM) base station operative to transmit a sequence of OFDM signals simultaneously using at least two separate twisted pairs, in which each of the OFDM signals is modulated by a plurality of sub-carriers. At least two converters are connected to the OFDM base station using the at least two twisted pairs, respectively, in which each of the converters, and simultaneously with the other converters, is configured to receive each of the OFDM signals from the OFDM base station using the respective twisted pair, up-convert the OFDM signal into a radio-frequency (RF) band, and re-transmit wirelessly the OFDM signal, in conjunction with the RF band, from at least one antenna associated with each converter.
