Abstract: Systems and methods for reducing fall back from long term evolution voice calls (VoLTE) to legacy systems. The system can include one or more lookup tables including ranges of internet protocol (IP) addresses for a plurality of user equipment (UE). The lookup tables can be stored on one or more network entities, such as on a proxy call session control function (PCSCF). In the event that a policy charging rules function (PCRF) is unable to establish a Gx session with the relevant packet gateway (PGW), the PCSCF can provide the name and/or the IP address for the appropriate PGW to the PCRF. The PCRF can then send a session request AVP to the IP address to cause the PGW to initiate Gx binding. The system enables VoLTE calls to be established despite problems with the PCRF and reduces fallback to legacy systems.

Abstract: A device, such as a base station or user equipment (UE), may identify a narrowband reference signal (NB-RS) energy per resource element (EPRE) for a NB-RS to be transmitted in a wireless transmission. The device may identify a ratio of a narrowband physical downlink shared channel (N-PDSCH) EPRE to the NB-RS EPRE for orthogonal frequency division multiplexing (OFDM) symbols containing neither a cell-specific reference signal (CRS) nor a NB-RS. In deployments where NB transmissions are transmitted in a guard-band adjacent to a wideband system bandwidth, a device may identify a second ratio for N-PDSCH EPRE to CRS EPRE within OFDM symbols containing CRS. In deployments where NB transmissions are transmitted in-band with the wideband system bandwidth, a device may identify a third ratio of NB-RS EPRE to CRS EPRE, and a fourth ratio of N-PDSCH EPRE to NB-RS EPRE within OFDM symbols containing NB-RS transmissions.

Abstract: A method and apparatus for selecting a carrier for a sidelink communication in a wireless communication system is provided. A user equipment (UE) receives an indication of an aggregated set of carriers among multiple carriers from the network. The aggregated set of carriers may be aggregated based on a destination of the sidelink communication. The UE selects a carrier among the aggregated set of carriers, selects a resource of the selected carrier, and performs the sidelink communication by using the selected resource of the selected carrier.

Abstract: The present disclosure relates to adaptive modulation and coding scheme selection and signaling in a communication system. In particular, a modulation and coding scheme to be used for transmission of a data is selected from a set of predetermined modulation and coding schemes. The predetermination of the set is performed by selecting the set from a plurality of predefined sets. The sets have the same size, so that a modulation and coding selection indicator signaled to select the modulation and coding scheme may be advantageously applied to any of the selected sets. Moreover, a second set includes schemes with a modulation not covered by the schemes of a first set, and which is of a higher order than any modulation in the first set.

Abstract: Disclosed is a mechanism to help control which of multiple carriers a base station will serve a UE on—perhaps which carrier should be the UE's primary component carrier for carrier-aggregation service. The disclosed mechanism can apply in a scenario where a base station is configured to provide service on multiple carriers including at least a first carrier and a second carrier, and when the base station is serving one or more relays respectively on each carrier. In that scenario, the selection of a carrier on which the base station should serve a UE could be made based at least on a consideration of how many UEs are served in total by the one or more relays that the base station serves respectively on each carrier, such as by selecting the carrier having the fewest such relay-served UEs.

The UE may identify, based at least in part on a value for each bit in the bitmap, one or more control resource block groups that are included in the CORESET. The UE may monitor for downlink communications in the one or more control resource block groups. Numerous other aspects are provided.

Abstract: A method in a proxy call session control function, P-CSCF, of handling an unauthenticated emergency call originating from a roaming user equipment, UE, which is not attached to the P-CSCF. The P-CSCF receives a SIP INVITE request from the UE, the INVITE request relating to the unauthenticated emergency call, and determines an IP address of the UE. The P-CSCF sends an identity query to a policy and charging rules function, PCRF, indicating the IP address of the UE and requesting other identifiers of the UE, and receives one or more other identifiers of the UE from the PCRF. The P-CSCF constructs a TEL and/or SIP uniform resource identifier, URI, for the UE on the basis of at least one of said other identifiers, inserts the URI into the SIP INVITE request, and sends the SIP INVITE request to a public safety answering point, PSAP. Also provided are corresponding methods in other nodes and for authenticated emergency calls, and apparatus for implementing the methods.
