  • Patent number: 10505851
    Abstract: Incoming data units within a network apparatus are temporarily buffered before being released to downstream components of the apparatus, such as a traffic manager or packet processor. A congestion detection component monitors for congestion with respect to particular subsets of the data units, such as data units that arrived over a same port or port group. When a metric, such as overutilization of the one or more buffers, indicates a state of congestion with respect to one of one of these subsets, various actions may be taken with respect to the subset to reduce the risk of complications from the congestion. In an embodiment, contrary to the expectation that a state of congestion would demand accelerating the release of data units from the buffer(s), a burst control mechanism is enabled. In an embodiment, the actions may further include temporarily pausing a lossless data stream and/or disabling features such as cut-through switching.

  • Patent number: 10505688
    Abstract: Various embodiments disclosed herein provide for efficient configuration of demodulation reference signals in beamformed wireless communications systems. In an embodiment, the transmitter can signal the location of demodulation reference signals (DMRS) by including an indicator bit in downlink control information indicating which DMRS scheme is used in the transmission. A first DMRS scheme can let the user equipment (UE) device know that the DMRS position for the PDSCH carrying the RMSI is as signaled on the master information block (MIB)—referred to as PDSCH Mapping Type A. A second DMRS scheme can let the UE device know that the DMRS position for the PDSCH carrying the RMSI is the first orthogonal frequency division multiplexing (OFDM) symbol of said PDSCH allocation—referred to as PDSCH mapping type B).

  • Patent number: 10498775
    Abstract: Non-text content may be exchanged in real time text (RTT) messages over a telecommunications network as part of an enhanced RTT (eRTT) service. A first UE can receive, from a second UE over a telecommunications network, capability information indicating whether the second UE is capable of exchanging text content and/or non-text content via RTT messages. Using this capability information, the first UE may determine whether to enable eRTT functionality on the first UE by determining whether to display a user interface element(s) in a selectable state on the display next to a RTT conversation window. The selectable user interface element(s), upon selection, allows a user of the first UE to create new non-text content, or select particular non-text content from available non-text content, for inclusion in a RTT message. The first UE may thereafter send non-text content in the RTT message to the second UE.

  • Patent number: 10477520
    Abstract: Various aspects of the disclosure relate to allocating control signaling resources for multiple carrier scenarios. In an example implementation, N-to-1 mapping is used between forward link control signaling resource allocation indices (e.g., control channel elements) and return link control signaling resources (e.g., for ACK/NACK signaling) indices in each return link component carrier. A collision between forward link control signaling assignments for different user terminals (UTs) may occur when UT-specific search spaces overlap each other. Such a collision may be avoided, for example, by scheduling different UTs on different return link component carriers, scheduling return link grants instead of forward link grants, or scheduling a different forward link control signaling candidate that is associated with a different forward link control signaling resource allocation index.

One electronic device includes a first radio, coupled to a first antenna and a second antenna, and a processing device coupled to the first radio. During a first period, the first radio transmits a sequence of data packets using the first antenna and the processing device receives a first metric value indicative of a first amount of power received on a third antenna of the second electronic device. During a second period, the first radio transmits the sequence using the second antenna and the processing device receives a second metric value indicative of a second mount of power received on the third antenna. The processing device selects one of the first antenna and the second antenna as a selected antenna based on which one of the first metric value and the second metric value is lower.

  • Patent number: 10470090
    Abstract: A user equipment (UE) and source base station may use data compression techniques for data packets sent between them. During a handover, the source base station may provide data compression context to a target base station, thus enabling the target base station to continue the data compression following the handover without having to reestablish the data compression context. The source base station may determine data compression capabilities of the UE or the target base station, or both, and may communicate the determined data compression capabilities to the UE or target base station. The source base station may identify at least one gap in a sequence of packets received from the UE, and communicate the existence of the gap to the target base station, which may request retransmission of packets associated with the gap.

  • Patent number: 10448410
    Abstract: A method is shown for allocating a plurality of channels to a plurality of radio nodes (RNs) in a radio access network (RAN). In accordance with the method, an initial RN is selected from among the plurality of RNs. A first of the plurality of channels is assigned to the initial RN. The first channel is selected such that external interference experienced by the initial RN from sources other than the RAN on the first channel is minimized. A second RN is selected from among the plurality of RNs. A second of the plurality of channels is assigned to the second RN. The second channel is selected such that a metric reflective of an information carrying capacity of the RNs that have already been assigned one of the plurality of channels is maximized. The assigned channels are allocated to the respective RNs to which they have been assigned.
