Abstract: Novel techniques are described for coexistence of multiple radio technologies in a shared frequency band. Techniques described herein enable multiple radiofrequency networks using different radio technologies to coexist on a same carrier frequency by exploiting various frequency- and/or time-domain sharing of scheduled resources. For example, data signals are received for transmission over different radio networks according to different radio technologies (having different respective sub-carrier definitions and timeslot definitions). A coexistence resource schedule is computed from the communication resource grids define an allocation of sub-carrier and/or timeslot resources among the radio technologies. Radio technologies can then be generated from the data signals in accordance with the coexistence resource schedule and the communication resource grids.

Abstract: A radio station (2) transmits or receives, to or from a radio terminal (1) in a second cell (23, 24), a CP message containing a NAS message or an RRC message or both, when a predetermined condition is satisfied. The second cell (23, 24) uses a RAT different from that of the first cell, and is used in addition and subordinate to the first cell. The predetermined condition relates to at least one of: (a) a content or type of the CP message; (b) a type of a signalling radio bearer used to transmit the CP message; (c) a transmission cause of the CP message; and (d) a type of a core network associated with the NAS message. It is thus, for example, possible to contributing to efficient transmission of control plane (CP) messages in a radio architecture that provides interworking of two different Radio Access Technologies (RATs).
