Abstract
As part of carrier assignment and configuration for multicarrier wireless communications, a single uplink (UL) primary carrier may provide control information for multiple concurrent downlink (DL) carriers. Optionally, control information for each DL carrier may be transmitted over paired UL carriers. Carrier switching of UL and/or carriers, including primary and anchor carriers, may occur during normal operation or during handover, and may occur in only the UL or only the DL direction. A unidirectional handover is performed when only an UL carrier or only a DL carrier is switched as part of a handover. Switching of UL and/or DL carriers may be from one component carrier or a subset of carriers to another component carrier, another subset of carriers, or all carriers in the same direction.
Claims (17)
1 . A base station comprising:
a processor configured to at least:
transmit, to a wireless transmit/receive unit (WTRU), a first radio resource control (RRC) message comprising a first configuration information that indicates a primary uplink (UL) carrier to be used to carry a first control type information, wherein the first control type information is associated with at least one downlink (DL) carrier of a first set of DL carriers;
receive, from the WTRU, the first control type information associated with the at least one DL carrier of the first set of DL carriers, wherein the first control type information is received via a physical uplink control channel (PUCCH) transmission on the primary UL carrier;
transmit, to the WTRU, a second RRC message comprising a second configuration information that indicates a non-primary UL carrier to carry a second control type information, wherein the second control type information is associated with at least one DL carrier of a second set of DL carriers; and
receive, from the WTRU, the second control type information associated with the at least one DL carrier of the second set of DL carriers, wherein the second control type information is received via a PUCCH transmission on the non-primary UL carrier.
2 . The base station of claim 1 , wherein the first control type information associated with the at least one DL carrier of the first set of DL carriers or the second control type information associated with the at least one DL carrier of the second set of DL carriers comprises one or more of a hybrid automatic request (HARQ) feedback, a channel quality information (CQI), or a channel state information (CSI).
3 . The base station of claim 1 , wherein the processor is configured to transmit a medium access control (MAC) control element (CE) indicating activation of the non-primary UL carrier.
4 . The base station of claim 1 , wherein the second RRC message indicates configuration information for assigning the non-primary UL carrier to carry the second control type information.
5 . A method implemented by a base station, the method comprising:
transmitting, to a wireless transmit/receive unit (WTRU), a first radio resource control (RRC) message comprising a first configuration information that indicates a primary uplink (UL) carrier to be used to carry a first control type information, wherein the first control type information is associated with at least one downlink (DL) carrier of a first set of DL carriers;
receiving, from the WTRU, the first control type information associated with the at least one DL carrier of the first set of DL carriers, wherein the first control type information is received via a physical uplink control channel (PUCCH) transmission on the primary UL carrier;
transmitting, to the WTRU, a second RRC message comprising a second configuration information that indicates a non-primary UL carrier to carry a second control type information, wherein the second control type information is associated with at least one DL carrier of a second set of DL carriers; and
receiving, from the WTRU, the second control type information associated with the at least one DL carrier of the second set of DL carriers, wherein the second control type information is received via a PUCCH transmission on the non-primary UL carrier.
6 . The method of claim 5 , wherein the first control type information associated with the at least one DL carrier of the first set of DL carriers or the second control type information associated with the at least one DL carrier of the second set of DL carriers comprises one or more of a hybrid automatic request (HARQ) feedback, a channel quality information (CQI), or a channel state information (CSI).
7 . The method of claim 5 , further comprising transmitting a medium access control (MAC) control element (CE) indicating activation of the non-primary UL carrier.
8 . The method of claim 5 , wherein the second RRC message indicates configuration information for assigning the non-primary UL carrier to carry the second control type information.
