  • Publication number: 20240090081
    Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for Fifth Generation New Radio (5G NR) frequency range two (FR2) based communications beam management. The UE may configure, via communications with a base station, serving the UE, a group ID for PUCCH resources within a group of PUCCHs, e.g., for FR2 based communications. The UE may receive, from the base station, an update to one or more PUCCH resources within the group of PUCCHs via a medium access control (MAC) control element (CE) that may include one of a resource ID indicating an update to a PUCCH resource or the group ID to update the group of PUCCH resources. The UE may update, based on the MAC-CE, the one or more PUCCH resources within the group of PUCCHs.

  • Publication number: 20240080780
    Abstract: Apparatuses, systems, and methods for providing maximum transmit power control when utilizing multiple radio access technologies. For example, a wireless communication device comprising two cellular radios may intend to transmit on the first radio, while concurrently transmitting on the second radio. To ensure compliance with a maximum transmit power limitation, the device may determine an allowed transmit power level of the first radio, representing a difference between the maximum transmit power limitation and the current transmit power level being transmitted by the second radio. The device may also determine a threshold power level for a communication by the first radio. If the allowed transmit power level meets the threshold power level, then the device may transmit the first communication having a power level between the threshold power level and the allowed transmit power level. Otherwise, the device may forego transmission of the first communication.

    Abstract: Apparatuses, systems, and methods for a wireless device to perform substantially concurrent communications with a next generation network node and a legacy network node. The wireless device may be configured to stablish a first wireless link with a first cell according to a RAT, where the first cell operates in a first system bandwidth and establish a second wireless link with a second cell according to a RAT, where the second cell operates in a second system bandwidth. Further, the wireless device may be configured to perform uplink activity for both the first RAT and the second RAT by TDM uplink data for the first RAT and uplink data for the second RAT if uplink activity is scheduled according to both the first RAT and the second RAT.

  • Patent number: 11877245
    Abstract: Apparatuses, systems, and methods to indicate power transmission capability for a wireless device. A wireless device may connect to a base station (BS). The wireless device may transmit information regarding transmit power capability to the BS. The wireless device may indicate support for full power transmit capability for a subset of TPMIs for which it provides full power transmit capability, e.g., in a bitmap. This subset of TPMIs may be less than all of the available TPMIs (i.e., it may be a strict subset of the available TPMIs). Full power transmission capability of these indicated TPMIs may be provided via antenna switching and/or antenna virtualization. The wireless device may perform uplink transmission to the BS according to the transmit power capability indicated in the information. For example, the UE may transmit data using the antenna virtualization related to the subset of the TPMIs.

  • Patent number: 11871346
    Abstract: This disclosure relates to using a wake up signal in conjunction with cellular communication in unlicensed spectrum. A cellular base station may provide a wake up signal on an unlicensed frequency channel after successful completion of a listen-before-talk procedure. The wake up signal may include a preamble configured for coherent detection, and information indicating channel occupancy time for a cellular communication by the cellular base station and a cell identifier for the cellular base station. A wireless device may monitor the unlicensed frequency channel for a wake up signal, and may determine whether to monitor the unlicensed frequency channel for control channel signaling based on whether a wake up signal is received, and potentially also based on the contents of the wake up signal if a wake up signal is received.

  • Publication number: 20230025057
    Abstract: Some embodiments include an apparatus, method, and computer program product for using group based reporting for beam management in a 5G wireless communications system. A user equipment (UE) can determine based on a signal-to-interference-plus noise ratio (SINR) or reference signal received power (RSRP) measurement, a ranking of two or more beam combinations, and transmit the ranking to a 5G node B (gNB). The UE can receive from the gNB, a transmission configuration indicator (TCI) codepoint that identifies a combination of two or more beams, where the TCI codepoint is based at least on the ranking. The UE can receive simultaneous transmissions via the combination, and transmit a report to the gNB that identifies by the TCI codepoint, SINRs that corresponds to the combination. In some embodiments the UE can simultaneously transmit on a second combination identified by a sounding reference signal (SRS) resource indicator (SRI) codepoint.

  • Patent number: 11540276
    Abstract: A device may wirelessly communicate according to a first radio access technology (RAT) within a first bandwidth part (BWP) of a frequency spectrum in which wireless communications according to other RAT(s) also take place. The device may be instructed to operate/communicate within a second BWP of the frequency spectrum responsive to the device successfully completing a listen-before-talk (LBT) procedure within a specified portion of the second BWP, where the second BWP contains the first BWP while the first BWP does not contain the specified portion of the second BWP. The device may also be instructed to operate/communicate within a specified frequency band (SFB) of the frequency spectrum responsive to the device successfully completing an LBT procedure within the SFB, where the SFB is not contiguous with the frequency band that includes the first BWP. The device may then simultaneously operate within the second frequency band and the first frequency band.
