Abstract: There is disclosed an apparatus comprising at least one processing circuitry, and at least one memory for storing instructions to be executed by the processing circuitry. The at least one memory and the instructions are configured to, with the at least one processing circuitry, cause the apparatus at least to configure a set of substitute functions. The apparatus is further caused to request a service user profile associated with a migration request. Still further, the apparatus is caused to create, based on the requested service user profile, a modified service user profile comprising the set of substitute functions, and to provide the modified service user profile.

Abstract: Improved techniques of reducing latency in UL positioning include generating a priority indication by the LMF for all UE requiring UL positioning. For example, an LMF can generate a priority list identifying UEs within a network that may be considered by a serving network node (gNB) for positioning prioritization. In some implementations, the serving gNB indicates that prioritizing all of the identified UEs would require more network resources than are available. In such a case, the LMF obtains latency measurement values for TRPs in the network. Based on the latency measurement values obtained, the LMF performs a configuration operation on at least one of the TRPs to reduce the UL positioning latency to an acceptable value.

Abstract: An optical line terminal (OLT) in flexible passive optical network (PON) transmits a downstream signal with two or more modulation formats, wherein at least one of the modulation formats is a modified PAMx modulation format and wherein x is greater than 2. The modified PAMx modulation encodes data bits such that the probability of at least one predetermined transition between amplitude levels is modified. Furthermore, an optical network unit (ONU) in the flexible PON is assigned to one of the plurality of modulation formats based on one or more parameters, such as configuration of the ONU and line conditions.

Abstract: According to an aspect, there is provided a first apparatus configured to perform the following. The first apparatus transmits a first notification message via a tunable small-form pluggable, SFP, module on a first channel over an optical transport network to a second apparatus by applying on-off keying to an optical transmitter of the SFP module. The first notification message includes information on the first channel. The first apparatus receives a first notification response message via the tunable SFP module from the second apparatus as an on-off keyed transmission on the first channel or a second channel. The first notification response message includes the information on the first channel. The first apparatus evaluates the first notification response message for acquiring the information on the first channel.

Abstract: Various example embodiments for supporting multicast are presented. Various example embodiments for supporting multicast are configured to support multicast, on a multicast tree for a multicast group, based on use of penultimate hop popping (PHP) on the multicast tree. Various example embodiments for supporting multicast are configured to support multicast, on a multicast tree for a multicast group, based on use of PHP on the multicast tree where the multicast tree is Point-to-Multipoint (P2MP) Multiprotocol Label Switching (MPLS) tree that is formed based on a TREE-SID multicast solution (although it will be appreciated that PHP may be applied on other types of multicast trees (e.g., other than P2MP MPLS multicast trees), on multicast trees formed based on other multicast solutions (e.g., other than TREE-SID), or the like, as well as various combinations thereof).

Abstract: Various communication systems may benefit from appropriate handling of uplink communications. For example, certain wireless communication systems may benefit from an uplink coverage extension for unlicensed band operation. A method can include configuring a first interlace having a first starting physical resource block. The method can also include configuring a second interlace having a second starting physical resource block offset from the first physical resource block. The method can further include transmitting or receiving a signal based on a combination of the first interlace and the second interlace. The combination can include at least one cluster but less than two clusters in each measurement interval.

Abstract: Apparatus and a method are disclosed for calibrating and tuning a wavelength-tunable semiconductor laser. In an assembly, the wavemeter is integrated with the laser, and plural temperature sensors are coupled to plural, spatially separated functional elements of the wavemeter by thermal conduction. A tuning circuit generates tuning signals for the laser that are responsive to wavemeter output signals and to temperature-indication signals from the plural temperature sensors. Temperature effects on the tuning can be mitigated.
