  • Publication number: 20100054203
    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.

  • Publication number: 20100040004
    Abstract: Systems and methodologies are described that facilitate assigning resources for an anchor carrier and an additional carrier with a grant message. The grant message communicated with an anchor carrier can include resource information a plurality of carriers. Moreover, the systems and methodologies that facilitate identifying control information for an anchor carrier and/or an additional carrier based upon an operating mode, wherein the operating mode is a legacy mode or an extended mode. Based on the operating mode, particular resources associated with control regions are monitored for control information for respective anchor carrier(s) or additional carrier(s).

  • Publication number: 20100034303
    Abstract: Aspects describe communicating grant information in a multicarrier wireless communication system. The grant information can be transmitted to mobile devices that have single carrier capability and/or mobile devices that have multicarrier capability. Grant information can be sent in a legacy control region and/or a non-legacy control region.

  • Publication number: 20100034163
    Abstract: Multiple downlink (DL) and uplink (UL) carriers can enhance wireless communication between nodes and user equipment (UE). Among the carriers, it is beneficial to have some special, by configuration designated carriers to provide synchronization, system information, paging, data and control for multi-carrier enabled UEs. Thereby, overhead system information can be reduced. For instance, synchronization and paging for a certain cell are not provided on all carriers. A carrier can provide backward compatibility for single carrier UEs for access, synchronization, broadcast, and new control region within the data region of the legacy terminals. Coordination between nodes for selecting anchor carriers that mitigate interference and for transmit power control for non-anchor carriers provide further network performance advantages.

  • Publication number: 20100035625
    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.

  • Publication number: 20090245194
    Abstract: Techniques 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 carrying 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.

  • Publication number: 20090238141
    Abstract: Systems and methodologies are described that facilitate system frame number (SFN) indication and identification during a random access procedure (e.g., associated with a handover). As described herein, a target cell can configure one or more Random Access Responses (RARs) designated for transmission to a terminal during the access phase of a handover to include the SFN of the target cell. Techniques are further described herein by which the target cell can include SFN information in a sub-header associated with a RAR, in the payload of a RAR, and/or in other appropriate manners. In addition, the target cell can configure one or more flags of the RAR to indicate the presence of SFN information. Upon receiving a RAR with embedded SFN information, a terminal can utilize the SFN for operations such as frequency hopping or uplink resource configuration as described herein.
