While a transmitter of a transceiver module of a user equipment is transmitting, a first receiver is operated on a first received signal, and a second receiver is operated on a transmitted signal from the transmitter. While the transmitter is not transmitting, the second receiver is operated on a second received signal. ## Claims ### Claim 1 Apparatus for use in wireless communication, the apparatus comprising: a transmitter; a first receiver; a second receiver; at least one processor; and at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus at least to: while the transmitter is transmitting: operate the first receiver on a first received signal; and operate the second receiver on a signal transmitted from the transmitter; and while the transmitter is not transmitting: operate the second receiver on a second received signal. ### Claim 2 (depends on 1) Apparatus according to claim 1, wherein the first receiver comprises a main receiver and the second receiver comprises a measurement receiver. ### Claim 3 (depends on 1) Apparatus according to claim 1, wherein the first received signal is received in a downlink operating band. ### Claim 4 (depends on 3) Apparatus according to claim 3, wherein the first received signal originates from a base station. ### Claim 5 (depends on 1) Apparatus according to claim 1, wherein the second received signal is received in an uplink operating band. ### Claim 6 (depends on 5) Apparatus according to claim 5, wherein the second received signal originates from a user equipment. ### Claim 7 (depends on 1) Apparatus according to claim 1, further comprising a directional coupler, wherein the signal to the second receiver passes through the directional coupler. ### Claim 8 (depends on 1) Apparatus according to claim 1, wherein operating the second receiver on the signal transmitted from the transmitter comprises at least one of antenna tuning and predistortion setting. ### Claim 9 (depends on 1) Apparatus according to claim 1, wherein operating the second receiver on a second received signal comprises at least one of reception of discovery signals and device-to-device transmissions. ### Claim 10 (depends on 1) Apparatus according to claim 1, wherein a relatively higher attenuation is applied to the signal received by the second receiver when operating on the transmitted signal, and a relatively lower attenuation is applied when operating on the second received signal. ### Claim 11 A method for use in wireless communication, the method comprising: while a transmitter is transmitting: operating a first receiver on a first received signal; and operating a second receiver on a signal transmitted from the transmitter, and while the transmitter is not transmitting: operating the second receiver on a second received signal, wherein the transmitter, first receiver and second receiver are comprised within a single transceiver module. ### Claim 12 (depends on 11) A method according to claim 11, wherein the first receiver comprises a main receiver and the second receiver comprises a measurement receiver. ### Claim 13 (depends on 11) A method according to claim 11, wherein the first received signal is received in a downlink operating band. ### Claim 14 (depends on 13) A method according to claim 13, wherein the first received signal originates from a base station. ### Claim 15 (depends on 11) A method according to claim 11, wherein the second received signal is received in an uplink operating band. ### Claim 16 (depends on 15) A method according to claim 15, wherein the second received signal originates from a user equipment. ### Claim 17 (depends on 11) A method according to claim 11, wherein the signal to the second receiver passes through a directional coupler. ### Claim 18 (depends on 11) A method according to claim 11, wherein operating the second receiver on the signal transmitted from the transmitter comprises at least one of antenna tuning and predistortion setting. ### Claim 19 (depends on 11) A method according to claim 11, wherein operating the second receiver on a second received signal comprises at least one of reception of discovery signals and device-to-device transmissions. ### Claim 20 (depends on 11) A method according to claim 11, wherein a relatively higher attenuation is applied to the signal received by the second receiver when operating on the transmitted signal, and a relatively lower attenuation is applied when operating on the second received signal. ### Claim 21 A non-transitory computer-readable storage medium having computer readable instructions stored thereon, the computer readable instructions being executable by a computerized device to cause the computerized device to: while a transmitter is transmitting: operate a first receiver on a first received signal; and operate a second receiver on a signal transmitted from the transmitter, and while the transmitter is not transmitting: operate the second receiver on a second received signal, wherein the transmitter, first receiver and second receiver are comprised within a single transceiver module within the computerized device.
