  • Publication number: 20230093484
    Abstract: User equipment (UE) applies a first code division multiplex access (CDMA) code to a baseband signal to generate a first signal, and a second CDMA code to the baseband signal to generate a second signal. The UE then transmits the first signal to a receiving device via a first antenna, and the second signal to the receiving device via a second antenna. The receiving device receives the first and second signals as a combined signal at an antenna, and extracts the first signal from the combined signal using the first CDMA code, and extracts the second signal from the combined signal using the second CDMA code. The CDMA codes may be real-valued or complex-valued. In some embodiments, the UE may separate the baseband signals into first and second portions, and transmit the first portion as part of the first signal and the second portion as part of the second signal.

  • Publication number: 20230007461
    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.

  • Publication number: 20220322351
    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.

  • Publication number: 20220312416
    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.

  • Publication number: 20220225418
    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.

  • Publication number: 20220225355
    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.

  • Publication number: 20210249768
    Abstract: An electronic device may be provided with wireless circuitry and control circuitry. The wireless circuitry may communicate with a wireless base station using a 5G New Radio (NR) communications protocol. The wireless circuitry may include a phased antenna array. The electronic device may perform antenna scaling operations in which the active antennas in the phased antenna array change over time to optimize wireless performance and power consumption. The electronic device may inform the base station when antenna scaling operations have occurred. This may allow the base station to compensate for power density discontinuities associated with the antenna scaling operations. If desired, the base station may break transmit and receive signal beam correspondence and the electronic device may use different antenna scaling settings for transmitting and receiving signals.
