Abstract: A wireless communication network schedules multiple components carriers on a same frequency band to user equipment (UE) for transmitting wireless signals. The network may indicate to the UE when to use each carrier, and the UE my switch between transmitting on each carrier. The UE may transmit multiple different signals on each carrier. In particular, the UE may include a local oscillator (LO) that generates a first frequency of a first carrier, and couple the LO to the transmission paths when transmitting using the first carrier. The UE may then cause the LO to generate a second of a second carrier, and couple the LO to the transmission paths when transmitting using the second carrier. Additionally or alternatively, the UE may include a second LO that generates the second frequency, and couple the second LO to the transmission paths when transmitting using the second carrier.

Abstract: User equipment (UE) may indicate a flexible direct current (DC) leakage location signaling capability to a network that facilitates transmission of accurate DC leakage locations to the network for improved reduction of negative impact of DC leakage on signal quality of uplink (UL) allocated resources. The UE may operate in the first DC leakage location signaling mode when only a single component carrier is activated, and indicate to the network one or more DC leakage locations corresponding to the single component carrier. Additionally, the UE may operate in the second DC leakage location signaling mode when at least a portion of two or more component carriers are activated, and enable the network to determine a default DC leakage location associated the two or more component carriers.

Abstract: An electronic device may communicate with a wireless base station using a 5G New Radio communications protocol. The base station may balance control timing and receiver performance for the devices in its cell by scheduling communications based on the communications capabilities of each device. This may ensure that the base station is able to provide communications with satisfactory control timing and receiver performance even if multiple different types of device are within its cell. In addition, the device may perform open loop transmit power control operations and then closed loop power control operations. To minimize complexity of the device, the device may only transmit at a maximum output power level during the open loop operations. If desired, the device may only transmit at the maximum output power level when the device is unable to decode a downlink reference signal transmitted by the base station within a predetermined number of symbols.

Abstract: Embodiments disclosed herein relate to techniques for measuring and/or detecting a signal-to-interference ratio (SIR) of a received signal at a user equipment (UE). The received signal may include a desired signal, co-channel interference, adjacent channel interference, and an in-band blocker. The UE may filter (e.g., remove) the various interferences and in-band blocker. The UE may determine or measure a power (or Received Signal Strength Indicator (RSSI)) of the desired signal and a power (or RSSI) of the co-channel interference separately because the desired signal and the co-channel interference overlap in frequency. To do so, the UE may determine a total power of the received signal including the desired signal and co-channel interference. The UE may receive the desired signal again while an uplink transmission is deactivated (and thus without the interference). The UE may then calculate the SIR based on the total power and the power of the desired signal.

Abstract: User equipment that is capable of filtering for an irregular bandwidth of an allocated channel may send an indication of this capability to a network, which may then configure the channel to a next higher standard channel size, enabling the user equipment to filter this larger channel bandwidth to the irregular bandwidth. User equipment that is not capable of filtering for the irregular bandwidth may send an indication that it does not have this capability to the network, which may then configure the channel to a next lower standard channel size, thus avoiding the need for the user equipment to filter a larger channel bandwidth to the irregular bandwidth. In cases where the network detects that a blocking signal is not present that may interfere with the allocated channel, the network may configure the channel to the next higher standard channel size.

Abstract: User equipment may configure a transmitter or receiver to conform to regulations or standards of a geographical region to communicate with non-terrestrial networks (e.g., satellite networks). In one embodiment, the user equipment may receive an indication of a regulation or standard to which to conform to from a terrestrial communication node, and apply an emission mask to the transmitter based on the regulation or standard. The user equipment may additionally or alternatively configure the receiver to be compliant with a noise level tolerance of a received signal specified by the regulation or standard. In some embodiments, the user equipment may implement a frequency offset between the received signal and an interfering signal associated with the noise level tolerance that is scaled based at least on a channel bandwidth associated with the desired signal. Moreover, the user equipment may scale the noise level tolerance based on the frequency offset.

Abstract: A wireless network may include a base station and user equipment (UE). The UE and base station may perform initial access operations at frequencies greater than or equal to 57 GHz without the use of transmit power control (TPC) signals. The UE devices and the base station may also perform connected mode operations at these frequencies without the use of TPC signals. The UE may perform power saving operations without the use of TPC signals. The base station may handle communications for multiple UE devices in its cell by partitioning the UE into groups based on the estimated path loss for each UE. The base station may perform TDMA, OFDMA, or a combination of TDMA/OFDMA scheduling for the UE devices. Performing these communications without TPC signaling maximizes the amount of network resources available for other purposes, simplifies communication scheduling, and maximizes the efficiency of the 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.
