Abstract: Systems and methods of using a frame structure by a NB-IoT UE are described, The UE receives an anchor segment on an anchor channel and a data segment on a data channel both in an unlicensed spectrum. If a 3N1 frame structure is used: a NPSS, NSSS and NPBCH are in a highest index anchor carrier of contiguous anchor carriers and SIB in a lowest index anchor carrier, and if a 3N2 frame structure is used a single narrowband carrier comprising the NPSS, NSSS, NPBCH and SIB. The data channel is a FHSS single carrier other than the anchor carriers if the 3N1 frame structure is used and the single narrowband carrier if the 3N2 frame structure is used. A NPDCCH or NPDSCH is received on a middle index anchor carrier or in the data segment. The NPSS overrides a TDD configuration indicated by the eNB.

Abstract: Configuring channel state information configuration parameters can reduce user equipment uplink feedback information. The user equipment can send the uplink feedback information to the network node by adapting the repetition factor based on one or more criteria. The repetition factor can be determined by the user equipment and/or a network node associated with the user equipment. Thus, reducing the frequency of reporting uplink feedback information can reduce power usage, signal interference, and increase battery life.

Abstract: User equipment (UE) includes processing circuitry, where to configure the UE for Single Radio Voice Call Continuity (SRVCC) handover from an LTE network to a legacy network with circuit switched (CS) communications, the processing circuitry is to encode a Session Description Protocol (SDP) message for transmission to a second UE within the LTE network.

The UE decodes an SRVCC handover command from an eNB within the LTE network, the handover command based on at least one packet loss rate (PLR) associated with a packet switched voice communication link between the UE and the second UE exceeding a PLR threshold that is determined based on the E2E_MAX_PLR that can be tolerated by the UE.

Abstract: In LTE a measurement configuration message, which instructs a terminal (10, 11, 12) on when to transmit a measurement report, is per frequency carrier dependent. A measurement object configuration for 5G/NR wireless communication is provided which is independent of carrier frequency, allowing multiple measurement objects to be configured for one particular carrier frequency. Each measurement object can be defined over a particular time duration (T1, T2, T3), frequency range, time/frequency grid, beam, and/or a particular frequency carrier (Layer 1, Layer 2) in order to satisfy various requirements on RRM measurement of NR. Thus, for a particular terminal (10, 11, 12) and a particular carrier frequency, a base station (20, 21, 22, 23) can define multiple measurement objects over different time/frequency grids.

Abstract: A novel method for performing replication of messages in a network that bridges one or more physical networks to an overlay logical network is provided. A physical gateway provides bridging between network nodes of a physical network and virtual machines in the overlay logical network by serving as an endpoint of the overlay logical network. The physical gateway does not replicate messages from the bridged physical network to destination endpoints in the overlay logical network directly, but instead tunnels the message-to-be-replicated to a designated tunnel endpoint in the overlay logical network. The designated tunnel endpoint in turn replicates the message that was tunneled to it to other endpoints in the overlay logical network.

Abstract: A transmission of information from a secondary to a primary node occurs in a plurality of transmission instances which are logical time durations. A secondary node receives an allocation of periodic transmission instances for a scheduling request indicator (SRI) and an allocation if periodic transmission instances for a sounding reference signal (SRS). In a particular transmission instance allocated for the transmission of both SRS and SRI, the secondary node transmits the SRI without transmitting the SRS if the SRI indicates a pending scheduling request; otherwise, the secondary node transmits the SRS without transmitting the SRI.
