Abstract: An improved NR-U framework allows a gNB to repeat RLM-RS with the same index over each sub-band of an unlicensed spectrum. For example, a RLM-RS with the same indices are repeated by the gNB over the sub-bands of a wideband channel in an unlicensed spectrum. By monitoring the different sub-bands, a UE may find one or more sub-bands in which the RLM-RS having a particular index is successfully transmitted at a subsequent time.

Abstract: A UE receives configuration for interference mitigation pattern(s) indicating which resource elements in a time-frequency resource space should be measured. The UE performs interference measurements based on the received one or more interference mitigation patterns. A network node determines configuration for interference mitigation pattern(s0 indicating which resource elements in a time-frequency resource space should be measured by a user equipment. The network node sends, toward the user equipment, the configuration for use by the user equipment to perform interference measurements of the one or more interference mitigation patterns.

Abstract: Systems, methods, apparatuses, and computer program products for efficient registration for partially supported service areas are provided. One method may include providing, to at least one user equipment registered to a network within a registration area, information comprising one or more lists of single network slice selection assistance information (S-NSSAIs) and one or more lists of tracking area identities (TAIs). The one or more single network slice selection assistance information (S-NSSAIs) is included in a list of rejected single network slice selection assistance information (S-NSSAIs) or in a list of extended rejected single network slice selection assistance information (S-NSSAIs), and is associated with a cause value indicating that the one or more single network slice selection assistance information (S-NSSAIs) is not supported uniformly in the registration area and is not supported in a current tracking area.

Abstract: An apparatus includes a processor; and a non-transitory memory including computer program code; wherein the memory and the computer program code are configured to, with the processor, cause the apparatus at least to: report at least two reported beams to a radio node; receive a configuration from the radio node for at least two configured beams, the at least two configured beams comprising a primary beam and at least one secondary beam; attempt to decode data based on the primary beam, per monitoring occasion for a downlink channel, based on the received configuration; in response to a failure to decode the data based on the primary beam, attempt to decode the data based on the at least one secondary beam over the downlink channel; and transmit or receive information over a scheduling occasion using at least one of the at least two configured beams following a successful decoding attempt.

Abstract: There is at least a method and apparatus to offload to or receive an offload at least one other cell of a same or different radio access technology at least one beam of more than one beam associated with at least one user equipment of the cell; and based on the determining, forwarding or receiving information including at least one control message identifying the at least one beam associated with the at least one user equipment of the cell to the at least one other cell to perform the offload to the cell, and to perform receiving, by user equipment of a cell of a communication network, from another cell of a same or different radio access technology information.

Abstract: Various techniques are provided for spectrum allocation. A method can include receiving a message including a first maximum power setting, a second maximum power setting, and a spatial range associated with the second maximum power setting, transmitting at least one first beam within the first maximum power in a spatial range excluding the spatial range associated with the second maximum power setting, and transmitting at least one second beam within the second maximum power in the spatial range associated with the second maximum power setting.
