Abstract: An outdoor device of a timing system includes a receiver for receiving clock information from a satellite system, a processing system for running master functionality of a clock synchronization protocol to transfer the clock information to an indoor device of the timing system, and a transceiver for transferring data between the outdoor device and the indoor device. A memory device stores a fixed delay value estimating a time delay from a reception moment of a request message related to the clock synchronization protocol to a transmission moment of a reply message. There is no need to compute a difference between clock times corresponding to the reception moment and the transmission moment because the fixed delay value is used in lieu of the difference in the clock synchronization protocol. Thus, quality requirements related to an oscillator of the outdoor device can be mitigated.

Abstract: Certain aspects of the present disclosure relate to a method and apparatus for receiving a medium occupation and a resource block group (RBG) size from a gNB, wherein the radio block group size is based on a bandwidth part (BWP) configuration. In one example, UEs with smaller BWP have finer granularity in RBG size in terms of PRBs, while UEs with larger BWP may have a coarser granularity in RBG size in terms of PRBs. An additional guard band may be used if the gNB reserves some channels such that not all of the BW is occupied. For example, if the gNB reserves the 20 MHz channel, it may perform better by adding additional guard band on each side of the 20 MHz bandwidth to accommodate an adjacent channel leakage-power ratio (ACLR). Another aspect of the present disclosure relates to assigning a UE an interlace with equally spaced PRBs.

Abstract: Systems, methods, and devices can be used to perform service-aware utilization of shared wireless resources. In various instances, a quality metric (e.g., a Bit Error Rate (BER)) of a shared wireless resource is determined. Requested services can be provided based at least partly on the quality metric and the type of services being requested. For example, when the quality metric exceeds a threshold and the requested services are for Quality of Service (QoS)-sensitive services (e.g., Guaranteed Bit Rate (GBR) services), the services can be provided at least partially via a licensed wireless resource. However, when the quality metric does not exceed the threshold, and/or the requested services are for non-QoS-sensitive services (e.g., non-GBR services), the services can be provided via the shared wireless resource.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, one or more downlink grants scheduling one or more corresponding downlink transmissions from the base station to the UE. In some examples, the UE may enter a state of sleep prior to receiving the one or more downlink transmissions. In such examples, the UE may wake up from the state of sleep at a first time that is at least a threshold period of time before a second time corresponding to a beginning of the one or more downlink transmissions. After waking up from the state of sleep, the UE may activate a notch filter and use the activated notch filter to filter a spur generated at the UE. The UE may receive the one or more downlink transmissions with improved reliability based on activating the notch filter.

Abstract: A radio node that dynamically exchanges information specifying available spectrum in a shared-license-access band of frequencies is described. During operation, the radio node may provide a first grant request to a computer, where the first grant request includes a request to reserve a first portion of the shared-license-access band of frequencies for use by the radio node. Then, the radio node may receive from the computer a grant response. When the grant response indicates that the first grant request is denied, the radio node may provide to a second radio node a first notification that the request for a first portion of the shared-license-access band of frequencies was rejected. Similarly, the radio node may receive from the second radio node a second notification that a request for a second portion of the shared-license-access band of frequencies was rejected.

Abstract: The present disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for layer 2 relay user equipment (UE) mobility. A relay UE relays data between a first network entity and a remote UE based on a first configuration of the remote UE. The relay UE may receive, from the first network entity on a first connection, a handover request that includes a second configuration for a second network entity or a third configuration for the remote UE. The relay UE determines whether dual active protocol stack radio link control channels are configured for the remote UE based on the first configuration or the third configuration. The relay UE establishes a second connection with the second network entity based on the second configuration, and transmits, to the remote UE, a handover status indicating a result of establishing the second connection with the second network entity.

Abstract: A wireless access node serves slice-capable User Equipment (UEs) and slice-incapable UEs. In the wireless access node, a radio exchanges slice data between the slice-capable UEs and a Baseband Unit (BBU). The radio exchanges non-slice data between the slice-incapable UEs and the BBU. The BBU exchanges the slice data with a wireless network slice and exchanges the non-slice data with a network element. The BBU determines its load for the slice-capable UEs. The BBU controls access to the wireless access node by new slice-incapable UEs based on the load for the slice-capable UEs.

Abstract: Methods, systems, and devices for wireless communications are described in which a transmitting device using shared radio frequency spectrum may perform a listen before talk (LBT) procedure for at least a minimum dwell time and, upon successful completion of the LBT procedure, may occupy the spectrum for up to a duration of a channel occupancy time (COT). The transmitting device may discontinue transmitting during the COT for a gap period, and resume transmitting subsequent to the gap period without performing another LBT procedure. The minimum dwell time may be based on a periodicity of a channel reservation signal transmitted by one or more other devices using the shared radio frequency spectrum. In some cases, the transmitting device may schedule one or more receiving devices with resources for transmissions during the COT, and the receiving devices may perform a LBT that is non-adjacent with an associated transmission.

Abstract: In one embodiment, a switched amplifier is provided to amplify a data transmission. The switched amplifier may use a control signal that is received via a control signal channel in a transmission cable. Also, the switched amplifier may detect signal power to determine whether the data transmission is received at one of a first port and a second port. Data transmissions via the data transmission channel occur in a first direction and a second direction in a same frequency range in a time division multiplex (TDD) mode. Also, the control signal and data transmission are diverted from the transmission cable that transmits a type of signal different from the control signal and the data transmission. The switched amplifier is controlled based on the control signal or the signal power detected. The amplified signal is diverted in the first direction or the second direction via the data transmission channel back to the transmission cable.
