Abstract: An apparatus including at least one processor and at least one memory storing instructions that when executed by the at least one processor cause the apparatus at least to perform receiving from a network node an indication of a second radio frequency carrier. The second radio frequency carrier is contained within a first radio frequency carrier over which the network node communicates. One or more out-of-band emission requirements for the apparatus are defined with respect to the first radio frequency carrier. The apparatus is further caused to perform determining at least one user equipment radio frequency requirement based on the second radio frequency carrier and transmitting a signal over the second radio frequency carrier based on the at least one user equipment radio frequency requirement and the one or more out-of-band emission requirements.

Abstract: A method, apparatus and computer program product are provided for defining a configured maximum output power of a user equipment. In the context of a method, a configured maximum output power of the user equipment in a respective slot for a carrier of a serving cell is determined based on at least one boundary. The at least one boundary is determined based at least partly upon a scaling factor dependent upon a number of antenna ports having a non-zero transmission power on a physical uplink shared channel (PUSCH). The method also reports the determined configured maximum output power to a network node operating the serving cell, thereby allowing the network to control the conditions of the uplink transmission more accurately.

Abstract: Systems, methods, apparatuses, and computer program products for configuring a user equipment to operate in carrier aggregation in a serving cell with a primary cell and one or more secondary cell are provided. For example, a method can include receiving, from a primary cell, a carrier aggregation configuration of a secondary cell with uplink. The configuration indicates that downlink is deactivated for the secondary cell. The carrier aggregation configuration is applicable to carrier aggregation of the primary cell and the secondary cell. The method also includes communicating with the secondary cell based on the configuration of the secondary cell.

Abstract: Systems, methods, apparatuses, and computer program products for reporting of achievable power per component carrier with multiple power sources and configuration based on such reporting are provided. For example, a method can include receiving a request to report user equipment band combination capabilities. The method can also include reporting a capability of a user equipment to a network. The capability can include indication of one or more component carrier groups per band combination or per band.
