Abstract
In one or more embodiments, there may be one or more devices, methods, and/or systems addressing or relating to carrier switching for sending uplink control information. In one case, a wireless transmit receive unit (WTRU) may have more than one uplink channel carrier available. The WTRU may determine, or be instructed, which carrier(s) to use in the event that a first carrier cannot be used. The WTRU may receive configuration information that may assist in determining which carrier to use.
Claims14
A method implemented by a wireless transmit receive unit (WTRU), the method comprising:
- receiving configuration information indicating a plurality of physical uplink control channel (PUCCH) carriers;
- receiving downlink control information (DCI) indicating a PUCCH resource associated with a first PUCCH carrier of the plurality of PUCCH carriers for sending a Uplink Control Information (UCI) transmission;
- and
- transmitting the UCI transmission on a second PUCCH carrier of the plurality of PUCCH carriers, wherein the second PUCCH carrier is selected based on an indication of cancelation for the UCI of the first PUCCH carrier.
A wireless transmit receive unit (WTRU), the WTRU comprising:
- a processor operatively coupled to a transceiver, the processor and transceiver configured to receive configuration information indicating a plurality of physical uplink control channel (PUCCH) carriers;
- the processor and transceiver configured to receive downlink control information, indicating a PUCCH resource associated with a first PUCCH carrier of the plurality of PUCCH carriers for sending a Uplink Control Information (UCI) transmission;
- and
- the processor and transceiver configured to transmit the UCI transmission on a second PUCCH carrier of the plurality of PUCCH carriers wherein the second PUCCH carrier is selected based on an indication of cancelation for the UCI of the first PUCCH carrier.
