Abstract: An electronic device may be provided with wireless circuitry and control circuitry. The wireless circuitry may communicate using a 5G New Radio (NR) protocol. The wireless circuitry may have multiple bandwidth part configurations. The control circuitry may place the wireless circuitry in a first bandwidth part configuration where a first bandwidth part of a first component carrier is active and a second bandwidth part of a second component carrier is inactive. The control circuitry may switch the wireless circuitry from the first bandwidth part configuration to a second bandwidth part configuration in which the first bandwidth part is inactive and the second bandwidth part is active. The first and second component carriers may be intra-band contiguous, intra-band non-contiguous, or inter-band. The control circuitry may switch the wireless circuitry into other configurations for covering other bandwidth parts of any desired component carriers in any desired bands.

Abstract: Embodiments disclosed herein relate to techniques for determining a maximum sensitivity degradation (MSD) value at a user equipment (UE), and sending the value to a network for scheduling a frequency band combination for uplink and/or downlink communication. The network configures the frequency band combination for the UE, and determines whether there may be potential interference when the UE uses the frequency band combination. If so, then the network sends an indication to the UE to deactivate uplink transmission. The UE then determines reference sensitivity (REFSENS) of its receiver when the network does not send a downlink transmission on the frequency band combination. The UE sets its transmitter to transmit with a predetermined (e.g., maximum) transmission power, sends uplink transmissions, and determines an interference power when operating using the frequency band combination. The UE then determines the MSD value based on the REFSENS and the interference power.

Abstract: Reporting UL Tx DC sub-carrier location information may include decoding a radio resource control (RRC) message received from a base station. The RRC message may comprise a configuration for dynamically reporting uplink (UL) transmit (Tx) direct current (DC) sub-carrier location information. A change associated with at boast one previous UL Tx DC sub-carrier location may be determined to have occurred, thereby creating at least one new UL Tx DC sub-carrier location. In response to determining the change, a medium access control (MAC) control element (MAC CE) may be encoded for transmission to the base station. The MAC CE may include information corresponding to the at least one new UL Tx DC sub-carrier location.

Abstract: Embodiments described herein include methods, systems, and apparatuses for allowing a user equipment (UE) that supports dynamic spectrum sharing (DSS) with uplink (UL)-shift to access a cell and barring UEs that do not support DSS with UL-shift. Embodiments may use a cell barring field in a master information block and additional filters to indicate a barring state for a network node.

Abstract: User equipment indicates its maximum aggregated bandwidth capability to a base station. The user equipment may also indicate a maximum bandwidth capability for each component carrier. Additionally or alternatively, the base station may assume that the maximum aggregated bandwidth capability is also supported by the user equipment for lower order carrier aggregation bandwidth classes having aggregated bandwidth upper limits greater than or equal to the maximum aggregated bandwidth capability. Further, the user equipment may indicate a maximum number of components carriers capable of supporting a maximum components carrier bandwidth. The user equipment may indicate the maximum aggregated bandwidth capability via a new signaling capability added to a standard (e.g., the Third Generation Partnership Project (3GPP) standard), or via existing signaling provided by the 3GPP standard, such as by using a frequency separation class signal.

Abstract: Systems and methods related to partial beam correspondence may be used to address potential limitations of beamforming wireless networks. A user equipment electronic device and/or wireless network identifies a subset of available transmitter beams for the user equipment electronic device that are indicated as similar to a downlink reference signal received at the user equipment electronic device from a wireless network node. The user equipment electronic device sweeps the subset of available transmitter beams for communication with the wireless network node and uses a best beam from the sweep to communicate with the wireless network node.

Abstract: Methods and systems include beamformed wireless communications to and from a user equipment electronic device. During operation of the user equipment electronic device, a change in slot aggregation is made. Using the aggregated slots, the user equipment electronic device and/or a wireless network utilize beam sweeps to determine a best beam pairing by repeating a shared channel in the aggregated slots with a beam sweep of multiple beams between the user equipment electronic device and the wireless network.

Abstract: An electronic device may transmit a communication request to a base station having an indication of a number of its receive branches and an indication of whether the communication request is designated as an urgent service fulfillment. The base station may delay a denial of the communication request until receiving the indication of whether the communication request is designated as using the urgent service fulfillment to reduce a likelihood of prematurely rejecting the communication request. The base station may also handover the communication request to a base station that supports the urgent service fulfillment. The base station may also be barred from transferring the user equipment to a frequency layer preferred by the base station when the communication request of the user equipment is designated as an urgent service fulfillment.

Abstract: Aggregated channel bandwidth classes that overlap in frequency are allocated for a fallback group. The fallback group may define an increased or maximum bandwidth of aggregated component carriers as allocated by a network. By enabling the aggregated channel bandwidth classes for a fallback group to overlap in frequency, for an available aggregated channel bandwidth, a first aggregated channel bandwidth class may be implemented using a first number of component carriers, and a second aggregated channel bandwidth class may be implemented using a second number of component carriers different from the first. The different number of component carriers may enable more flexibility to more fully utilize the available aggregated channel bandwidth for communication. The network may then allocate one of these aggregated channel bandwidth classes to user equipment that more fully utilizes the available aggregated channel bandwidth for communication
