  • Patent number: 11974235
    Abstract: Activating an uplink (UL) gap at a base station may include decoding a user equipment (UE) UL gap capability report received from a UE. A radio resource control (RRC) UL gap configuration may be encoded for transmission to the UE. A power headroom report (PHR) medium access control (MAC) control element (CE) received from the UE may be decoded. The PHR MAC CE may include at least one of a P value or a power management maximum power reduction (P-MPR) value. Decoding the measurement information may include determining that the P value is equal to one or the P-MPR value is greater than zero. Based on determining that the P value is equal to one or the P-MPR value is greater than zero, the UL gap configuration may be implicitly activated.

  • Publication number: 20240138008
    Abstract: Some aspects of this disclosure relate to apparatuses and methods for communicating in a first radio access technology (RAT) and a second RAT. A user equipment (UE) can receive, from a first base station using the first RAT, first configuration information for the UE to communicate with a second base station via the second RAT; and receive, from the first base station using the first RAT, a downlink message to enable a communication link between the UE and the second base station via the second RAT. The downlink message includes second configuration information for the UE to communicate with the second base station via the second RAT. The UE can establish the communication link between the UE and the second base station using the second RAT based on a link configuration obtained from the first configuration information and the second configuration information.

  • Publication number: 20240097861
    Abstract: User equipment may transmit and receive wireless signals to and from various communication networks. Furthermore, user equipment may indicate usage capabilities to the various wireless communication networks to enable the user equipment to transmit and/or receive wireless signals to and from at least two different communication networks. In particular, the user equipment may indicate usage capabilities of supporting both Frequency Range 2 (FR2) wireless signals of a fifth generation (5G) network and 7-24 gigahertz (GHz) wireless signals of a sixth generation (6G) network in an intermediate frequency range of the user equipment. The communication network(s) may then configure and/or schedule the user equipment based on the usage capabilities to enable the user equipment to simultaneously or non-simultaneously communicate using both the FR2 wireless signals and the 7-24 GHz wireless signals while preventing interference in the intermediate frequency range of the user equipment.

  • Publication number: 20240097760
    Abstract: A base station may transmit beams to user equipment. The user equipment may receive the beams and transmit a signal to a base station. The base station may determine signal characteristics associated with the beams based on the signal and compare the signal characteristics with predefined signal characteristics that correspond to potential locations of the user equipment. Based on this comparison, the base station may determine a position of the user equipment and transmit a targeted beam based on the position of the user equipment. The base station may also track the position of the user equipment and provide an updated targeted beam based on an updated position of the user equipment. Accordingly, the base station may efficiently form and update the targeted beam based on the predefined signal characteristics, thereby reducing an amount of time required to establish and maintain communication with the user equipment.

  • Publication number: 20240097773
    Abstract: A distributed multi-antenna system includes a first access point configured to emit first beams to a user equipment device. The first access point is also configured to receive, from the user equipment device, an indication of a first beam selected from the first beams via a beam sweeping procedure. The distributed multi-antenna system also includes a second access point configured to receive, from the user equipment device or the first access point, the indication. The second access point is also configured to emit a second beam of second beams corresponding to the second access point to transmit data to the user equipment device based on the indication and a location of the second access point.

  • Publication number: 20240097743
    Abstract: A system may include an access point (AP), user equipment (UE), and a reconfigurable intelligent surface (RIS). The RIS may include an array of elements coupled to adjustable devices controlled to cause the array to reflect signals in different directions. The RIS may be controlled in a first mode in which the AP controls the adjustable devices, a second mode in which the UE controls the adjustable devices, and a third mode in which the RIS controls the adjustable devices. The RIS, AP, or UE may determine which mode to place the RIS in based on a downlink signal transmitted by the AP, an uplink signal transmitted by the UE, measurements of the signals performed on the RIS, a first distance or round trip time between the AP and the RIS, and/or a second distance or round trip time between the UE and the RIS.

  • Publication number: 20240089155
    Abstract: A first device may transmit a first symbol for a second device and a second symbol for a third device. The first device may generate a first dictionary and a second dictionary that satisfy a complementary rule. The first device may modulate the first symbol onto an entry from the first dictionary to produce first modulated data and may modulate the second symbol onto an entry from the second dictionary to produce second modulated data. The first device may generate a third symbol as a joint modulation of the first and second modulated data and may transmit the third symbol using a resource element. The second device may decode the third symbol based on the first dictionary to recover the first symbol. The third device may decode the third symbol based on the second dictionary to recover the second symbol. Privacy may be maintained between the second and third devices.

  • Publication number: 20240090052
    Abstract: Systems and methods described herein may enable an electronic device to communicate using both a first communication system based on a first frequency spectrum (e.g., New Radio (NR)/Fifth Generation (5G) network frequencies) and a second communication system based on a second frequency spectrum (e.g., sub-terahertz (sub-THz) frequencies, Sixth Generation (6G) network frequencies)). The two communication systems may share some front-end processing circuitry, which may help with reducing complexity and footprints of sub-THz communication systems.

  • Publication number: 20240031933
    Abstract: A wake-up signal (WUS) network (separate from a cellular network) includes WUS nodes that broadcast WUSs targeting WUS receivers of user equipment (UE). The WUSs may have low frequencies, such as within a television whitespace spectrum. When the cellular network determines that a UE should enter a power saving mode, or when a cellular receiver of the UE enters an idle state, the cellular network may request resources for the UE from a WUS node and activate a WUS receiver of the UE. When the cellular network has data to send to the UE or a threshold time has expired, the cellular network may request a WUS from the WUS network, which broadcasts the WUS that may be received by the UE. If the UE has data to transmit to the cellular network, the cellular network may request that the WUS node stop providing resources to the UE.
