A mobile wireless communications device comprising: a housing; a wireless receiver carried by the housing and configured to receive communication signals over a first wireless frequency range; a wireline transmitter carried by the housing and configured to transmit communication signals overlapping in frequency with the first wireless frequency range; wherein the wireless receiver is further configured to also receive communication signals over a second wireless frequency range that is not overlapping in frequency with the communication signals transmitted from the wireline transmitter; and a controller carried by the housing and coupled with the wireless receiver and the wireline transmitter, characterised in that the controller is configured to: receive an indication of an incoming communication signal; determine a first time when the wireless receiver is to begin receiving based on said indication and, based thereon, switch the wireline transmitter to a suspended communication mode during which transmission is disabled within a time duration (T start) before the first time, and determine a second time when the wireless receiver has completed receiving and, based thereon, switch the wireline transmitter to a normal communication mode in which transmission is enabled and wherein the controller is configured to not switch the wireline transmitter to the suspended communication mode when the wireless receiver is to begin receiving communication signals via the second wireless frequency range. a housing; a wireless receiver carried by the housing and configured to receive communication signals over a first wireless frequency range; a wireline transmitter carried by the housing and configured to transmit communication signals overlapping in frequency with the first wireless frequency range; wherein the wireless receiver is further configured to also receive communication signals over a second wireless frequency range that is not overlapping in frequency with the communication signals transmitted from the wireline transmitter; and a controller carried by the housing and coupled with the wireless receiver and the wireline transmitter, characterised in that the controller is configured to: receive an indication of an incoming communication signal; determine a first time when the wireless receiver is to begin receiving based on said indication and, based thereon, switch the wireline transmitter to a suspended communication mode during which transmission is disabled within a time duration (T start) before the first time, and determine a second time when the wireless receiver has completed receiving and, based thereon, switch the wireline transmitter to a normal communication mode in which transmission is enabled receive an indication of an incoming communication signal; determine a first time when the wireless receiver is to begin receiving based on said indication and, based thereon, switch the wireline transmitter to a suspended communication mode during which transmission is disabled within a time duration (T start) before the first time, and determine a second time when the wireless receiver has completed receiving and, based thereon, switch the wireline transmitter to a normal communication mode in which transmission is enabled and wherein the controller is configured to not switch the wireline transmitter to the suspended communication mode when the wireless receiver is to begin receiving communication signals via the second wireless frequency range.
