Abstract: A method and apparatus for non-terrestrial network beam switching is provided. A non-terrestrial network base station includes a transmitter configured to transmit downlink data to user equipment and a receiver configured to receive uplink data from the user equipment. A channel bandwidth of the non-terrestrial network base station is divided into a plurality of bandwidth parts respectively corresponding to a plurality of geographic areas, and each bandwidth part is respectively associated with a satellite beam. When the user equipment is located in a first geographic area, the transmitter transmits the downlink data to the user equipment over a corresponding first bandwidth part. After the user equipment transitions from the first geographic area to a second geographic area, the transmitter transmits the downlink data to the user equipment over a corresponding second bandwidth part of the plurality of bandwidth parts.

Abstract: Various arrangements for improving cell coverage are presented. A cellular network can define a first bandwidth part and a second bandwidth part to be implemented concurrently by a base station of the cellular network. The first bandwidth part and the second bandwidth part do not overlap and may be separated by a guard band. The first bandwidth part can have a greater bandwidth and greater sub-carrier spacing than the second bandwidth part. The cellular network can determine a first set of user equipment to use the first bandwidth part for communication with the base station and a second set of user equipment to use the second bandwidth part for communication with the base station. Communication with the first set of user equipment using the first bandwidth part and the second set of user equipment using the second bandwidth part may be performed.

Abstract: Various arrangements for using different air interfaces on adjacent frequency channels for side-link communications are presented. A first side-link channel may be split into a first bandwidth portion and the second bandwidth portion, in which the first bandwidth portion of the first side-link channel is directly adjacent to the second side-link channel. A first subcarrier spacing may be assigned to the first bandwidth portion of the first side-link channel. The second side-link channel may also use the first subcarrier spacing. A second subcarrier spacing may be assigned to the second bandwidth portion of the first side-link channel that differs from the first subcarrier spacing.

Abstract: A system and method for managing interference between different enterprises operating over the same spectrum. The system includes central units of a host, a first enterprise and a second enterprise; a first interface for connecting the central unit of the host to the central unit of the first enterprise; and a second interface for connecting the central unit of the host to the second enterprise; wherein the central unit of the host is configured to: enable relaying of load information between the first and second enterprises to minimize interference between each enterprise when the first and second enterprises are operating in the same spectrum and an overlapping coverage region between cell sites; and arbitrate transmission requests from a respective enterprise based on information from service level agreements (SLAs) shared between the central unit at the host and the respective enterprise.

Abstract: A base station of a cellular network determines that a mobile device is in an ON period of a discontinuous reception (DRX) cycle. The base station determines that a number of data units in a buffer corresponding to the mobile device is at least a threshold value. The threshold value is a number greater than one. In response to determining that the number of data units in the buffer is at least the threshold value and that the mobile device is in the ON period, the base station initiates transmission, to the mobile device over the cellular network, of at least some of the data units in the buffer. Some implementations include a latency timer that can trigger initiation of data unit transmission.

Abstract: A system for scheduling wireless data transmissions divides a band allocated to the mobile service carrier into two overlapping bands. Then each user equipment (UE) of a plurality of UEs that connects to the ground-based network of the mobile service carrier is assigned to one of the two overlapping bands. The system allocates at a given scheduling time, physical resource blocks (PRBs) to UEs up to a maximum number of PRBs available for the particular overlapping frequency band to which the UE is assigned based on a metric for the UE that is a ratio of a downlink channel quality indicator for the UE to the average data rate of the UE at the given time, giving higher priority for PRB allocation to UEs that have a larger metric than other UEs of the plurality of UEs.

Abstract: Methods and systems for scaling energy consumption in wireless network infrastructure, while retaining the ability to quickly scale when load changes. This end is accomplished by using containerized (or virtualized) applications to implement 5G core Network Functions, and utilizing network redundancy/geo-redundancy or a multihoming transport protocol for communication between these containerized (or virtualized) applications and other 5G system elements such as the network functions of the Radio Access Nodes (RANs) or the network functions of 5G Core. In particular, one or more core Network Functions (NFs) are instantiated as containerized applications executing on one or more virtualized hosts in a cloud-native orchestration environment. The containers are selectively activated or deactivated based on a demand for utilization of the associated NF. Because elements of the 5G RAN, 5G Core and one or more NFs are connected to one another via a protocol that supports network redundancy and/or geo-redundancy and/or multihoming, endpoint addressing need not be reconfigured when demand on the NFs changes.
