摘要： Methods and Devices that provide mechanisms for an air interface capability exchange are disclosed. The air interface capability exchange enables a user equipment device to signal its air interface configuration capabilities to a network device to facilitate software configurable air interface (SoftAI) optimization. The air interface capability exchange involves a UE device signaling information regarding an air interface configuration capability type of the device's air interface. The air interface configuration capability type identifies whether the device supports multiple air interface configurations of the air interface. The UE device may also transmit information regarding air interface configuration options that it supports. The network device may determine a configuration for the UE device's air interface based at least in part on the information provided by the UE device.

摘要： In a cellular network supporting both legacy standard-compliant mobile terminals and next generation standard-compliant mobile terminals, both legacy reference signals and next generation reference signals are supported. A method of operation of a MIMO transmitter compliant with both standards includes: defining a matrix of resource blocks within an information channel of the cellular network, wherein each resource block corresponds to a region of subcarriers of a transmission timeslot at a given frequency subband; assigning a first set of reference signals (RSs) for the legacy standard-compliant mobile terminals to resource blocks at specific locations within the matrix to be transmitted by the MIMO transmitter, the specific locations being defined by the legacy standard; and assigning a second set of RSs for the next-generation standard-compliant mobile terminals to other resource blocks within the matrix to be transmitted by the MIMO transmitter.
