Abstract
In a wireless network supporting aggregation of uplink component carriers sounding reference signals SRS are transmitted (62) on an uplink UL primary component carrier. An activation command corresponding to an UL secondary component carrier SCC is received (64) in response to which the receiving transceiver determines (65) whether it has valid timing information for the UL SCC wherein valid timing information for the UL SCC indicates that the UL SCC is UL synchronized. In response to this determination transmission of SRS on the UL SCC is enabled (66) if the UL SCC is synchronized when SRS is configured for the UL SCC. Otherwise transmission of SRS on the UL SCC is prohibited (68) until the UL SCC is UL synchronized.

Claim
1. A method, in a wireless transceiver, of reducing interference in a wireless communication system that supports uplink carrier aggregation, the method comprising:', 'transmitting (62) sounding reference signals, SRS, on an uplink, UL, primary', 'component carrier; and', 'receiving (64) an activation command corresponding to an UL secondary component carrier, SCC;', 'characterized in that the method further comprises:', 'determining (65) whether the wireless transceiver has valid timing information for the UL SCC, wherein valid timing information for the UL SCC indicates that the', 'UL SCC is UL synchronized; and,', 'in response to said determining, enabling (66) transmission of SRS on the UL SCC when SRS is configured, if the UL SCC is synchronized, and otherwise prohibiting (68) transmission of SRS on the UL SCC until the UL SCC is UL synchronized.
2. The method of claim 1 , wherein determining whether the wireless transceiver has valid timing information for the UL SCC comprises:', 'determining (71 ) that the UL SCC belongs to a pre-determined group; and determining (76) that the UL SCC is UL synchronized if any member of the group is', 'UL synchronized, and otherwise determining (78) that the UL SCC is not UL synchronized.
3. The method of claim 2, further comprising:', 'receiving timing information for at least one member of the pre-determined group; and,', 'in response to the timing information, enabling transmission of SRS on the UL SCC when SRS is configured.
4. The method of claim 3, wherein the timing information is a timing advance command received in a MAC control element.
5. The method of claim 3, wherein said timing information is a timing advance command received in response to a random access procedure performed in response to a random access order for at least one member of the pre-determined group.
6. The method of claim 3, wherein said timing information is a timing advance command received in response to a terminal-initiated random access procedure.
7. The method of claim 1 , wherein determining whether the wireless transceiver has valid timing information for the UL SCC comprises receiving a flag at the wireless transceiver, the flag indicating whether the wireless transceiver has valid timing information for the UL SCC.
8. A wireless transceiver (52) for use in a wireless communication system that supports uplink carrier aggregation, the wireless transceiver (52) comprising:', 'a radio circuit (80) adapted to receive signals on at least one downlink carrier and to transmit signals on a plurality of uplink carriers, the uplink carriers including an uplink, UL, primary component carrier, PCC, and an UL secondary component carrier, SCC; and', 'a processing circuit (82) operatively connected to the radio circuit and adapted to: transmit sounding reference signals, SRS, on the UL PCC, using the radio circuit (80); and', 'receive an activation command corresponding to the UL SCC, via the radio circuit (80);', 'characterized in that the processing circuit (82) is further adapted to:', 'determine whether the wireless transceiver (52) has valid timing information for the UL SCC, wherein valid timing information for the UL SCC indicates that the UL SCC is UL synchronized; and,', 'in response to said determining, enable transmission of SRS on the UL SCC when SRS is configured, if the UL SCC is synchronized, and otherwise prohibit transmission of SRS on the UL SCC until the UL SCC is UL synchronized.
9. The wireless transceiver (52) of claim 8, wherein the processing circuit (82) is configured to determine whether the wireless transceiver has valid timing information for the UL SCC by:', 'determining that the UL SCC belongs to a pre-determined group; and', 'determining that the UL SCC is UL synchronized if any other member of the group is', 'UL synchronized, and otherwise determining that the UL SCC is not synchronized
10. The wireless transceiver (52) of claim 9, wherein the processing circuit (82) is further configured to:', 'receive timing information for at least one member of the pre-determined group; and, in response to the timing information, enable transmission of SRS on the UL SCC when SRS is configured.1. The wireless transceiver (52) of claim 10, wherein the timing information is a timing advance command received in a MAC control element
12. The wireless transceiver (52) of claim 10, wherein the timing information is a timing advance command received in response to a random access procedure performed in response to a random access order for at least one member of the pre-determined group
13. The wireless transceiver (52) of claim 10, wherein said timing information is a timing advance command received in response to a terminal-initiated random access procedure
14. The wireless transceiver (52) of claim 8, wherein the processing circuit (82) is configured to determine whether the wireless transceiver has valid timing information for the UL SCC by receiving a flag at the wireless transceiver, the flag indicating whether the wireless transceiver has valid timing information for the UL SCC.']
