Methods and apparatus for communicating uplink data signals simultaneously with device to device data signals
A wireless communications device, e.g., a mobile wireless terminal, is controlled by a base station to simultaneously: (i) transmit uplink data signals in an uplink spectrum to a base station and (ii) transmit device to device data signals in the uplink spectrum to another wireless communications device. In various embodiments, the uplink data signals are communicated in a first multi-antenna stream corresponding to a first multi-antenna configuration and the device to device data signals are communicated in a second multi-antenna stream corresponding to a second multi-antenna configuration. Control information communicated from the base station to the wireless communications device being controlled include, e.g., a selected first antenna configuration for uplink data signaling, a selected second antenna configuration for device to device data signaling, a selected first maximum transmission power level for uplink data signaling and a selected second maximum transmission power level for device to device data signaling.
