    Abstract: A method a computer program product and an apparatus for determining retransmission feedback resources are provided. An apparatus receives a downlink resource assignment over a control channel and obtains an offset related to a region for retransmission feedback resources. The offset is determined based on a type of the control channel. The apparatus determines resources for communicating retransmission feedback for communications received over the downlink resource assignment based on an index of a resource related to the downlink resource assignment and the offset. The apparatus transmits retransmission feedback for the communications over the resources.

    Abstract: A method, an apparatus, and a computer program product operable in a wireless communication system are provided in which a pairing is determined between one or more uplink carriers and one or more downlink carriers. The one or more uplink carriers and the one or more downlink carriers include at least three carriers. On which carrier to exchange control information on one or more of the carriers is based on the pairing or an anchor carrier designation.

    Abstract: DYNAMIC ASSIGNMENT OF ACK RESOURCE IN A WIRELESS COMMUNICATION SYSTEMTechniques for dynamically assigning acknowledgement (ACK) resource to a user equipment (UE) are described. For dynamic scheduling, a scheduling message may be used to send scheduling information for a single transmission of data. For semi-persistent scheduling, a scheduling message may be used to send a semi-persistent assignment for multiple transmissions of data. In an aspect, at least one field of a scheduling message, which is normally used to carry scheduling information for dynamic scheduling, may be re-used to carry an ACK resource assignment for semi-persistent scheduling. In one design, a UE may receive a scheduling message canying a semi-persistent assignment and may obtain an assignment of ACK resource from the at least one field of the scheduling message. The UE may receive a transmission of data sent in accordance with the semi-persistent assignment, determine ACK information for the transmission of data, and send the ACK information with the ACK resource.Figure 3

    Abstract: Techniques for reporting channel state information (CSI) are disclosed. A user equipment (UE) may be configured for operation on multiple carriers with different configurations, e.g., FDD and TDD carriers and/or carriers with different uplink- downlink configurations. The multiple carriers may have different subframes for making measurements for CSI and/or different subframes for sending CSI. In response to a CSI request, the UE may determine at least one reference subframe to use for determining CSI for the multiple carriers. The reference subframe may be common to the plurality of carriers and may, for example, be based the subframe in which the CSI request in sent. Alternatively, the reference subframe may be different for different carriers such as when it is based on different HARQ timelines applicable for the different carriers. The UE may determine the CSI for the multiple carriers based on the reference subframe(s) and may report the CSI.

    Abstract: Techniques for sending feedback information for multi-carrier operation are described. In an aspect, feedback information for data transmissions on multiple downlink carriers may be sent on at least one uplink resource determined based on at least one downlink resource used to send at least one downlink grant for the data transmissions. In another aspect, feedback information for data transmissions on multiple downlink carriers may be sent with reduced or no orthogonal spreading to enable more feedback information to be sent. In yet another aspect, feedback information for data transmissions on multiple downlink carriers may be sent with channel selection. A UE may send a transmission of at least one signal value on at least one resource to convey acknowledgement (ACK) information for data transmissions on multiple downlink carriers. The signal value(s) and resource(s) may be determined based on the content of the ACK information.

    Abstract: Techniques for sending control information in a wireless communication system are described. A user equipment (UE) may be configured to periodically send control information (e.g., CQI information) and may receive an assignment of control resources for sending the control information. The UE may also receive an assignment (e.g., a dynamic assignment or a semi-persistent assignment) of data resources for sending data. The UE may send the control information (i) on the control resources if the control and data resources do not coincide in time or (ii) on a designated portion of the data resources if the control and data resources coincide in time. The UE may generate at least one SC-FDMA symbol with the control information sent on the control resources or the designated portion of the data resources. The UE can maintain a single-carrier waveform for each SC-FDMA symbol.
