  • Patent number: 11412038
    Abstract: Techniques for performing network-assisted peer discovery to enable peer-to-peer (P2P) communication are described. In one design, a device registers with a network entity (e.g., a directory agent) so that the presence of the device and possibly other information about the device can be made known to the network entity. The network entity collects similar information from other devices. The device sends a request to the network entity, e.g., during or after registration. The request includes information used to match the device with other devices, e.g., information about service(s) provided by the device and/or service(s) requested by the device. The directory agent matches requests received from all devices, determines a match between the device and at least one other device, and sends a notification to perform peer discovery. The device performs peer discovery in response to receiving the notification from the network entity.

  • Patent number: 11382109
    Abstract: Aspects of the disclosure provide for a thin control channel structure that can be utilized to enable multiplexing of two or more data transmission formats. For example, a thin control channel may carry information that enables ongoing transmissions utilizing a first, relatively long transmission time interval (TTI) to be punctured, and during the punctured portion of the long TTI, a transmission utilizing a second, relatively short TTI may be inserted. This puncturing is enabled by virtue of a thin channel structure wherein a control channel can carry scheduling information, grants, etc., informing receiving devices of the puncturing that is occurring or will occur. Furthermore, the thin control channel can be utilized to carry other control information, not being limited to puncturing information. Other aspects, embodiments, and features are also claimed and described.

  • Publication number: 20220210838
    Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) receiving a configuration message from a base station for supporting random access channel (RACH) type selection by the UE. The configuration message may include one or more reference signals and one or more link quality thresholds corresponding to the one or more reference signals. The UE may generate measurements of the reference signals and determine link quality for communications between the UE and the base station based on the measurements. Based on a comparison between the link quality to corresponding link quality thresholds, the UE may select a two-step random access procedure, a four-step random access procedure, or both for establishing a connection with the base station. In some cases, the UE considers system loading information, transmission parameters, or random access rules in selecting the random access procedure.

  • Patent number: 11374711
    Abstract: Systems and techniques are disclosed to enhance the efficiency of available bandwidth between UEs and base stations. A UE transmits a sounding reference signal (SRS) to the base station. The base station characterizes the uplink channel based on the SRS received and, using reciprocity, applies the channel characterization for the downlink channel. As part of applying the channel information, the base station forms the beam to the UE based on the uplink channel information obtained from the SRS. The UE may include an array of antennas, each UE transmitting a different SRS that the base station receives and uses to characterize the downlink. Multiple UEs (or a single UE with multiple antennas) transmit SRS at the same time and frequency allocation (non-orthogonal), but with each sending its own unique SRS. Further, multiple UEs (or a single UE with multiple antennas) may send their SRS at unique time/frequency allocations (orthogonal).

  • Patent number: 11362921
    Abstract: Disclosed are techniques for determining round-trip times (RTTs) between a user equipment (UE) and multiple base stations. In an aspect, the UE transmits an RTT measurement signal whose arrival time is measured by each of the base stations, and each of the base stations returns an RTT response signal whose arrival times are measured by the UE. In another aspect, the base stations each transmit an RTT measurement signal and the UE returns an RTT response signal. The receiver of the RTT measurement signal may include the measured arrival time in a payload of the RTT Response signal. Alternatively, the measured arrival time(s) of the RTT Measurement signal(s) and the transmission time(s) of the RTT Response signal(s) are sent in a separate message. The RTT signals can be wideband signals using low reuse resources.
