摘要： Techniques for sending control information on a variable control channel are described. Different structures for mapping control information to control channel resources may be used depending on various factors such as operating configuration, the available resources for the control channel, the type(s) of control information being sent, the amount of control information being sent for each type, whether or not data is being sent, etc. In one design, at least one type of control information being sent may be determined and may comprise channel quality indicator (CQI) information, acknowledgement (ACK) information, and/or other types of control information. A structure of the control channel may be determined based on operating configuration (e.g., system configuration such as asymmetry of downlink and uplink allocations) and/or other factors. The at least one type of control information may be mapped to the resources for the control channel based on the structure.

摘要： Systems and methodologies are described that facilitate multiplexing of control information and data for common transmission in a localized FDM wireless communication system. Localized FDM transmission of control and data channels can be achieved by, for example, multiplexing control information with data and transmitting the control information and data using resources and transmission schemes specified for transmission of the data. To ensure the reliability of control information multiplexed with data, a power offset can be applied to the control information to provide varying protection levels for the control information based on properties of the data resources into which it is embedded in order to maintain a predetermined signal quality for the control information independent of the data resources.

摘要： Techniques for paging user equipments (UEs) in a wireless communication system are described. In one aspect, a cell sends a paging indicator to a UE, monitors for an acknowledgement from the UE, and sends a page message to the UE if an acknowledgement is received from the UE. The cell may receive channel quality information from the UE and may send the page message with link adaptation and/or HARQ to improve performance. In another aspect, a cell sends a paging indicator on a shared control channel to a UE and sends a page message on a shared data channel to the UE. The paging indicator and page message may be sent from multiple cells to the UE. Alternatively, the paging indicator may be sent from multiple cells to the UE, and the page message may be sent from a single cell to the UE.

摘要： Techniques for supporting MIMO transmission are described. User equipments (UEs) are classified into a first group of UEs to be scheduled individually and a second group of UEs that can be scheduled together. The classification may be based upon the number of transmit and receive antennas, sector loading, data requirements, long-term channel statistics, the number of UEs, etc. Channel quality indicator (CQI) information received from the UEs is interpreted in different manners depending on the groups to which the UEs belong. A single UE may be selected at a time from the first group or multiple UEs may be selected at a time from the second group for MIMO transmission. A MIMO transmission may be sent to a single UE in the first group or multiple UEs in the second group at rates selected based upon the CQI information.

摘要： Systems and methodologies are described that facilitate employing circular buffer based rate matching. Encoded block(s) that include systematic, parity 1, and parity 2 bits can be generated using turbo code. Bit type can be identified to separate bits into distinct groups. Systematic bits can be interleaved together to generate a randomized sequence of systematic bits, parity 1 bits can be interleaved together to yield a randomized sequence of parity 1 bits, and parity 2 bits can be interleaved together to output a randomized sequence of parity 2 bits. The randomized sequences of parity 1 bits and parity 2 bits can be interlaced together in an alternating manner. The randomized sequence of systematic bits can be inserted into a circular buffer, and upon inserting the entire sequence, the interlaced parity bits can be inserted into the circular buffer (e.g., until reaching capacity). Bits inserted into the circular buffer are transmitted.

摘要： Systems and methodologies are described that facilitate searches for a cell in a wireless communication environment. A mobile device can employ a searcher that can detect timing information respectively associated with PSCs and cells to determine the cell with the highest correlation. The searcher can detect SSCs, which can include detecting associated phase information, to determine the SSC with the highest correlation, CP length, and/or other information to facilitate identifying a desired cell having the strongest signal to establish communication between the mobile device and the desired cell. PSCs respectively associated with cells can have different positions in the symbol sequences, and SSCs can respectively be phase shifted at different angles to facilitate detection and identification of a cell(s), where a PSC can be utilized as a phase reference by the associated SSC.

摘要： Techniques for supporting broadcast, multicast, and unicast services in a cellular system are described. A Node B may multiplex data for broadcast and multicast services and data for unicast services on radio resources available for transmission. The Node B may periodically send scheduling information used to determine the radio resources carrying the broadcast and multicast services. In one design, the Node B may time division multiplex the data for the broadcast and multicast services and the data for the unicast services. The scheduling information may convey time unit(s) used for each broadcast or multicast service. In another design, the Node B may map the data for the broadcast and multicast services to time frequency blocks. The scheduling information may (i) convey the time frequency block(s) used for each broadcast or multicast service or (ii) point to control information conveying the time frequency block(s) used for each service.

摘要： Systems and methodologies are described that facilitate sending a power control command in a wireless communication environment. A base station can send a power control command to a UE through resource elements reserved for at least one Physical Downlink Control Channel (PDCCH). Thus, the power control command can be punctured into a control channel element (CCE) reserved for the at least one PDCCH. Further, the base station can convey an indicator that specifies the resource elements reserved for the at least one PDCCH used for sending the power control command to the UE. Moreover, the base station can use a structure similar to a conventional (e.g., Release 8, . . . ) PHICH structure for sending the power control command using the resource elements reserved for the at least one PDCCH. For example, the power control command can be spread using one or more Walsh codes assigned to the UE.
