Communication Over Free Space Patents (Class 370/310)
  • Patent number: 11363615
    Abstract: Communication equipment communicating in a licensed frequency band identifies unused unlicensed communication resources within an unlicensed frequency band. The communication equipment uses the identified unlicensed communication resources to communicate within the unlicensed frequency band. In some circumstances, the unused unlicensed communication resources are identified based on resource information received from a base station where the resource information identifies unlicensed communication resources that will be used by the base station. In other circumstances, the unused unlicensed communication resources are identified based on frequency band measurements of the unlicensed frequency band over an observation time duration longer than a sensing time duration used by unlicensed equipment using the unlicensed frequency band.

  • Patent number: 11265954
    Abstract: In this invention, we disclose methods for enabling ad hoc cellular base station functionality within a user equipment when the connection quality between a base station and the user equipment is limited or nonexistent. These methods include measuring a connection quality between a user equipment and its serving base station. If the connection quality is below a threshold, the user equipment can enable its internal ad hoc cellular base station functionality. This is done by running a software within the user equipment that (a) checks the connection quality periodically, and (b) enables ad hoc cellular base station functionality of the connection threshold dips below a certain value. In one embodiment, that threshold could be the same threshold value that a user equipment would use if it were making a decision to handoff to another base station based on poor connection quality.

    Abstract: A wireless device may receive packets according to a protocol, such as Bluetooth, and may rapidly react to receive an interfering RF packet instead of dropping the first RF packet and the interfering RF packet, to decrease message delay due to collisions in high device density environments. When a received signal strength indicator (RSSI) difference between the interfering RF packet and the first RF packet exceeds a threshold, the device may detect the interfering packet and resync a portion of its circuitry to lock on to and receive the interfering packet. The wireless receiver may detect the interfering RF packet by detecting one or more of: a specific resync byte sequence, an increase in RSSI, or a phase shift.

  • Patent number: 11229030
    Abstract: The present invention provides a method for transmitting an uplink signal, a terminal, and a network device. In one aspect, in embodiments of the present invention, by receiving configuration information of a zero-power uplink reference signal transmitted by a network device, and determining resources occupied by the zero-power uplink reference signal according to the configuration information, no uplink data is transmitted over the resources, and/or no non-zero-power uplink reference signal is transmitted over the resources. Since resources are pre-reserved on a terminal, the interference with uplink reference signals transmitted by other terminals over pre-reserved resources caused by uplink signals transmitted by the terminal over the pre-reserved resources is effectively avoided, and reliable transmission of the uplink reference signals of the terminal can be ensured, thereby improving the transmission performance of these uplink reference signals.

  • Patent number: 11212764
    Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for determining that synchronization for sidelink communication is based on a synchronization source type, and identifying a priority level for a sidelink transmission. The described techniques also include selecting a modified timing error requirement for the sidelink transmission based at least in part on determining that the synchronization source type is the synchronization source for sidelink communications, and the identified priority level, and sending the sidelink transmission using the modified timing error requirement. In some examples, a sidelink device may identify an MCS for sending the sidelink transmission, and may select the modified timing error requirement for the sidelink transmission based on the MCS.

  • Patent number: 11212850
    Abstract: Techniques are described herein for network slice support of respective transport protocols. In one example, a session management function obtains, from a user equipment, a request for a network slice identifier in a network that includes a plurality of network slices each configured to support a respective transport protocol. In response to the request, the session management function identifies a first transport protocol of the respective transport protocols by which the user equipment is to communicate. Based on the first transport protocol, the session management function identifies a first network slice of the plurality of network slices by which the user equipment is to communicate. The first network slice is configured to support the first transport protocol. The session management function provides the network slice identifier to the user equipment. The network slice identifier corresponds to the first network slice.

  • Patent number: 11212702
    Abstract: The present technology relates to a signal processing apparatus and method which are able to suppress a reduction in reception sensitivity. A reception signal is compressed so as to have a predetermined signal level or lower, and transmission data transmitted from a transmitter side and included in the reception signal compressed so as to have the signal level or lower is decoded. For example, an approximate replica signal reproducing large amplitude changes of the reception signal is generated, and the approximate replica signal is subtracted from the reception signal to compress the reception signal so as to have the signal level or lower. The present disclosure is applicable to, for example, a signal processing apparatus, a reception apparatus, a transmission/reception apparatus, a communication apparatus, an information processing apparatus, an electronic device, a computer, a program, a storage medium, a system, and so on.

  • Patent number: 11212328
    Abstract: Methods, apparatuses, and systems are provided for improving utilization of a communications system through various atom-based techniques for enhancing the viewing experience for Internet protocol content. Some embodiments exploit atom-based processing to determine which content atoms to broadcast (e.g., multicast) over which channels to which subscribers. Other embodiments make atom-based filtering, caching, and/or other determinations at the user terminal. For example, low-level (e.g., physical layer) filtering may be used to limit the amount of user-layer processing needed, and to facilitate delivery of content to those users most likely to desire that content. Still other embodiments allow users to create customized channels of cached content for viewing as a shared channel. Embodiments include techniques for addressing synchronization of channel content and viewing, and social networking, for subscribers to the shared channel.
