`ABSTRACT
`(57)
`Methods and systems for transmitting uplink control infor
`mation and feedback are disclosed for carrier aggregation
`systems. A user equipment device may be configured to
`transmit uplink control information and other feedback for
`several downlink component carriers using one or more
`uplink component carriers. The user equipment device may
`be configured to transmit such data using a physical uplink
`control channel rather than a physical uplink shared channel.
`The user equipment device may be configured to determine
`the uplink control information and feedback data that is to be
`transmitted, the physical uplink control channel resources to
`be used to transmit the uplink control information and
`p
`feedback data, and how the uplink control information and
`feedback data may be transmitted over the physical uplink
`control channel.

`data), such as a Physical UL Shared Channel (PUSCH), then
`the L1/2 UCI may be transmitted in a UL resource specially
`assigned for UL L1/2 control on a physical uplink control
`channel (PUCCH). What are needed in the art are systems
`and methods for transmitting UCI and other control signal
`ing utilizing the capabilities available in an LTE-A System,
`including carrier aggregation.
`
`SUMMARY
`
`Methods and systems for transmitting uplink control
`information (UCI) and other feedback data, in particular
`HARO ACK/NACK, in wireless communications system
`using carrier aggregation are disclosed. In an embodiment,
`a UE may be configured to determine the particular infor
`mation bits that are to be transmitted as part of UCI or other
`feedback data. A UE may also be configured to determine
`the particular resources that may be used to transmit feed
`back when such transmission is to be performed using
`PUCCH resources. A UE may also be configured to deter
`mine how to transmit such feedback, for example, by
`determining the encoding to be used, the appropriate symbol
`mapping, the transmission power settings, and other aspects
`of feedback transmission.
`More specifically, a UE may be configured to determine
`a codebook size and/or implement methods of reducing
`codebook size and/or states used in a codebook. A UE may
`also be configured to determine when a PDCCH reception is
`missed and/or detect a false positive PDCCH reception. A
`UE may also be configured to determine the appropriate
`PUCCH resources for HARQ ACK/NACK feedback and
`where within PUCCH that such feedback is to be located. A
`UE may also be configured to perform methods of bundling
`ACK/NACK on PUCCH. In an embodiment, a UE may be
`configured to determine static ACK/NACK resources. In a
`further embodiment, a UE may be configured to perform
`PUCCH resource selection using DL SPS. A UE may also be
`configured to use multiplexing with PUCCH for UCI and
`feedback data. A UE may also be configured to determine
`PUCCH resources using a CCE index.
`In an embodiment, a UE may be configured to determine
`channel coding and physical resource mapping for feedback,
`such as HARQ ACK/NACK. A UE may also be configured
`for multiplexing feedback data with feedback data from
`other UEs, and for simultaneously transmitting SRS with
`feedback data. In an embodiment, a UE may be configured
`to use extended cyclic prefix in transmitting feedback data.
`A UE may also be configured to account for unequal
`robustness when performing channel selection. A UE may
`be configured to handle SR in various ways disclosed herein.
`A UE may also be configured to determine transmit power
`when transmitting feedback data using PUCCH. These and
`additional aspects of the current disclosure are set forth in
`more detail below.
`
`BRIEF DESCRIPTION OF THE DRAWINGS
`
`The following detailed description of disclosed embodi
`ments is better understood when read in conjunction with the
`appended drawings. For the purposes of illustration, there is
`shown in the drawings exemplary embodiments; however,
`the subject matter is not limited to the specific elements and
`instrumentalities disclosed. In the drawings:
`FIG. 1A is a system diagram of an example communica
`tions system in which one or more disclosed embodiments
`may be implemented.
`
`25
`
`In order to Support higher data rate and spectrum effi
`ciency, the Third Generation Partnership Project (3GPP)
`Long Term Evolution (LTE) system has been introduced into
`3GPP Release 8 (R8). (LTE Release 8 may be referred to
`herein as LTE R8 or R8-LTE.) In LTE, transmissions on the
`uplink are performed using Single Carrier Frequency Divi
`sion Multiple Access (SC-FDMA). In particular, the SC
`FDMA used in the LTE uplink is based on Discrete Fourier
`30
`Transform Spread Orthogonal Frequency Division Multi
`plexing (DFT-S-OFDM) technology. As used hereafter, the
`terms SC-FDMA and DFT-S-OFDM are used interchange
`ably.
`In LTE, a wireless transmit/receive unit (WTRU), alter
`natively referred to as a user equipment (UE), transmits on
`the uplink using only a limited, contiguous set of assigned
`sub-carriers in a Frequency Division Multiple Access
`(FDMA) arrangement. For example, if the overall Orthogo
`nal Frequency Division Multiplexing (OFDM) signal or
`system bandwidth in the uplink is composed of useful
`sub-carriers numbered 1 to 100, a first given WTRU may be
`assigned to transmit on sub-carriers 1-12, a second WTRU
`may be assigned to transmit on Sub-carriers 13-24, and so
`on. While the different WTRUs may each transmit into only
`a subset of the available transmission bandwidth, an evolved
`Node-B (eNodeB) serving the WTRUs may receive the
`composite uplink signal across the entire transmission band
`width.
`LTE Advanced (which includes LTE Release 10 (R10)
`and may include future releases such as Release 11, also
`referred to herein as LTE-A, LTE R10, or R10-LTE) is an
`enhancement of the LTE standard that provides a fully
`compliant 4G upgrade path for LTE and 3G networks. In
`LTE-A, carrier aggregation is Supported, and, unlike in LTE,
`multiple component carriers (CCs) may be assigned to the
`uplink, downlink, or both. Such carriers may be asymmetric
`(a different number of CCs may be assigned to the uplink
`than the number of CCs assigned to the downlink.) Note that
`CCS may also be known as cells, and in this disclosure the
`terms are used interchangeably.
`In both LTE and LTE-A, there is a need to transmit certain
`associated layer 1/layer 2 (L1/2) uplink control information
`(UCI) to support the uplink (UL) transmission, downlink
`(DL) transmission, scheduling, multiple-input multiple-out
`put (MIMO), etc. In LTE, if a WTRU has not been assigned
`an uplink resource for UL transmission of data (e.g., user
