Abstract: Various arrangements for transitioning the bandwidth allocation of a cellular network, such as at a base station, are presented. Bandwidth parts may be defined for communication with the cellular network, such as on a per-base station basis. At a given time, two of these bandwidth parts may be actively used for communication by different UE for communication with the base station. A determination to adjust a bandwidth allocation may be made. A series of transitions may be performed to migrate from the first two of these bandwidth parts to the second two of the bandwidth parts such that interference does not occur.

Abstract: Various arrangements for using multiple air interfaces on a frequency channel for side-link communications are presented. Side-link communications may be performed using the first air interface during only a first time-window of a system resource pool while side-link communications may be performed using a second air interface during a second time-window of the system resource pool.

Abstract: A new radio base station establishes a first and a second component. The first and second component carrier overlap each other. The base station transmits first synchronization signal blocks on the first component carrier. The base station transmits second synchronization signal blocks on the second component carrier interleaved in time with the first synchronization signal blocks.

Abstract: Systems and methods for communication link adaptation and communication networks involving ground-based user equipment and non-terrestrial stations. A communication is received indicating signal quality of a first signal transmitted during a first transmission period and a plurality of fading losses associated with the first signal are obtained. A first fading loss and a second fading loss associated with the first signal are estimated for a future time, the first fading loss based on application of a first filter, and the second fading loss based on differences determined between the first fading loss and the plurality of fading losses. A signal-to-interference-plus-noise-ratio is calculated and includes at least one of the first fading loss and the second fading loss. A non-terrestrial station transmits, for a second time period, a second signal having settings determined based on the signal-to-interference-plus-noise-ratio.

Abstract: Various systems and methods for scheduling data transmissions from a base station to user equipment (UE) are presented. Channel quality indicator values that correspond to multiple UE may be determined for multiple carrier components of a cellular network's carrier aggregation. A scheduling matrix may be created that includes instantaneous data transfer rates for the UE. Elements within the scheduling matrix may be normalized by modifying instantaneous data transmission rates using average data transmission rates. Scheduling decisions for data transfers may be made for the UE based on the normalized scheduling matrix.

Abstract: Various arrangements for performing uplink grant-free transmissions are presented herein. An instance of user equipment (UE) may determine data that is to be transmitted using a grant-free (GF) uplink transmission to a base station of a cellular network. The UE may select a first GF resource block and a second GF resource block. The UE may transmit GF transmissions that comprise: a data payload and a first pointer at the first GF resource block; and the data payload and a second pointer at the second GF resource block. The first pointer may refer to the second GF resource block, while the second pointer may refer to the first GP resource block.

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 arrangement of compound cellular networks that accommodate multiple cellular communication protocols are presented. A compound cellular network may connect user equipment (UE) with a data network using a first anchor point. The compound cellular network may transition the UE from the first anchor point to a second anchor point. Following the transitioning, the compound cellular network may connect the UE with the data network using the second anchor point. The UE may then be transitioned from the second anchor point to a converged anchor point of the compound cellular network. The UE may be locked to the converged anchor point while the UE is communicating with a second cellular network that communicates using the second cellular communication protocol.

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.
