  • Patent number: 11950137
    Abstract: Methods, systems, and devices for wireless communications are described in which two or more UEs of a wireless communications system may establish a sidelink connection. A first UE that is initiating sidelink communications may evaluate whether the sidelink connection can support a quality of service (QoS) for a data flow prior to admitting the data flow. The first UE may evaluate a link quality with one or more other UEs that are to use the data flow on the sidelink connection, evaluate system congestion of time/frequency resources that are available for the sidelink connection, or any combinations thereof, and admit the data flow based on the evaluation. A link quality of the sidelink connection may be determined based on a type of communication associated with the data flow, such as unicast communications with one other UE, multicast communications with multiple other UEs, or broadcast transmissions to multiple UEs.

  • Patent number: 11937243
    Abstract: A method for allocating resources for a scheduling request indicator (SRI) is disclosed. An SRI cycle period for use by user equipment (UE) within a cell is transmitted from a NodeB in a cell to UE within the cell. The NodeB transmits a specific SRI subframe offset and an index value to the particular UE within the cell. The specific SRI subframe offset and the index value enable the UE to determine a unique combination of cyclic shift, RS orthogonal cover, data orthogonal cover, and resource block number for the UE to use as a unique physical resource for an SRI in the physical uplink control channel (PUCCH).

  • Patent number: 11924755
    Abstract: Method, apparatus, and computer program product for a user equipment in a wireless communications system to receive configuration information that has one or more TCI-states. With this configuration information, the user equipment can then determine inactivity on TCI-states. Based on that determination, the user equipment enables either a discontinuous monitoring or a cessation of monitoring on those TCI-states. Each TCI-state corresponds to a radio beam and also corresponds to an antenna panel. By reducing such monitoring, the use equipment can deactivate antenna panels corresponding to the TCI-states. The determination can be done through the use of a timer with various time thresholds based on the TCI-state. The activity being transmitted on those beam can be scheduling received by the user equipment from a network element such as a base station. The TCI-states can also be grouped and the functionality of the invention dealt with on a group basis.

    Abstract: A multiple-input multiple output transmit and receive system includes a first antenna that transmits a first signal at a channel frequency that propagates in a first path and that simultaneously receives a pilot signal at the channel frequency with the transmitting the first signal at the channel frequency, where the pilot signal propagates in a second path. A single-channel duplex transmit-receive system is coupled to an output of the first antenna. A processor is coupled to an output of the single-channel duplex transmit-receive system and configured to determine channel state information of the first path at the channel frequency using the received pilot signal.

  • Patent number: 11818653
    Abstract: Embodiments herein relate to a method performed by a radio unit (101) for controlling power levels of spatially separated transceivers (110-119) connected to the radio unit (101) via corresponding antenna ports (a-j). Each transceiver (110-119) is capable of performing measurements on uplink transmissions from wireless devices in a wireless communication network (100). The radio unit (101) receives, from each transceiver (110-119), measurements on uplink transmissions from wireless devices. Then, the radio unit (101) determines, for each transceiver (110-119), a load based on how many wireless devices that have the transceiver as the transceiver with the most relevant measurement for its uplink transmissions. The radio unit (101) also controls a power level of at least one first transceiver (110) based on at least one of the determined loads for the transceivers (110-119). Embodiments of the radio unit (101) are also described.

  • Patent number: 11805460
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive data from both a source base station and a target base station during handover. For example, the UE may refrain from resetting or reestablishing media access control (MAC) and packet data convergence protocol (PDCP) layer configurations until after a successful access procedure is performed with the target base station. In some cases, a single radio link control (RLC)/PDCP stack may be used during handover procedures. A source base station may, for example, forward data to a target base station after receiving a handover execution message. A UE may identify and resolve any duplicate data sent by both base stations during the transition. Additional signaling may be used (e.g., during the radio resource control (RRC) configuration) to indicate that a UE supports dual link handover.

The method includes identifying available access networks receiving media streams, accepting steering rules from the administrative domain, incrementing a counter that measures the amount of media streams arriving on the available access networks during a measurement interval, adjusting a delay value based on a timer value, the total amount of media arriving on the access networks, and the steering rules. The timer value may be set to the measurement interval and the measurement interval may be provided in the steering rules. Then, the method includes the multipath-capable sender sending acknowledgments which are delayed according to the adjusted delay value.

  • Patent number: 11792782
    Abstract: A wireless user equipment (UE) device is configured to communicate with another UE via device-to-device (D2D) communications. The UE transmits a communication to the other UE, wherein the communication indicates scheduling of a shared spectrum resource. The shared spectrum resource is shared by a first network management operator (NMO) and a second NMO, wherein both the UE and the other UE are associated with the first NMO. The first NMO employs a first set of spatial channels in the shared spectrum resource, and a second set of spatial channels in the shared spectrum resource is made available for use by the second NMO, the second set being different from the first set. The UE communicates with the other UE over the first set of spatial channels.

  • Patent number: 11792694
    Abstract: When initiating a Voice-over-IP (VoIP) communication session between an originating device (MO) and a terminating device (MT) on a packet-switched network, network components associated with the MO may encounter a failure when preparing resources for the session, such as a failure to establish a dedicated bearer with the MO. This might typically cause the system to abort the session. Instead, the network components are configured to detect the failure and to initiate a handover to a circuit-switched communication network so that the session may be conducted through the circuit-switched communication network. The failure may be detected by a component of a Long-Term Evolution (LTE) Radio Access Network (RAN) of the network, by a Mobility Management Entity (MME) of the network, or by some other network component. Single Radio Voice Call Continuity (SRVCC) procedures may be used to implement the handover.

  • Patent number: 11778521
    Abstract: A system is proposed to provide handover in a mobile telecommunications environment, particularly applicable to 3GPP networks, which does not increase signalling overhead but minimises user data loss during handover. In the modified system, PDCP SDUs with Sequence numbers are buffered and retransmitted as necessary. At the time of handover, SDUs not received by the user device are forwarded to the target base station for forward transmission to the UE. The handover procedure is designed to minimise packet loss whilst keeping to a minimum the duplication of packet transmission over the air interface.
