摘要： Techniques for supporting communication on multiple carriers are disclosed. In one design, a user equipment (UE) is configured with a base carrier and a dependent carrier linked to the base carrier. Data transmission on the dependent carrier is scheduled via a scheduling carrier, which is different from the dependent carrier. The UE receives a scheduling grant on the scheduling carrier and determines whether the scheduling grant is for the base carrier and/or the dependent carrier. The UE communicates (e.g., sends or receives data) on the base carrier and/or the dependent carrier based on the scheduling grant. The scheduling grant may be (i) a separate grant carrying scheduling information for only one carrier, (ii) a common grant carrying scheduling information for both carriers, (iii) a joint grant carrying separate scheduling information for each carrier, or (iv) a composite grant that may be a separate grant, a common grant, or a joint grant.

摘要： Systems and methodologies are described that facilitate arrangement and transmission of control information in a wireless communication system. As described herein, a scheduled transmission of acknowledgement (ACK) signaling and channel quality information (CQI) signaling in a common subframe can be adapted for network implementations with limited link budget wherein ACK signaling is configured for repetition over multiple subframes to ensure a desired error rate level for the ACK signaling. To these ends, various aspects described herein facilitate modification of a coding rate applied to ACK signaling to be transmitted with data based on a repetition factor of the ACK signaling. Additionally and/or alternatively, various aspects described herein facilitate dropping of CQI signaling and transmission of only ACK signaling on subframes where CQI and ACK signaling are to be transmitted substantially simultaneously and ACK transmission is configured for repetition over multiple subframes.

摘要： Systems and methodologies are described that facilitate adaptive uplink pilot multiplexing schemes. In various embodiments, frequency position and pilot channel bandwidth can be adaptively varied in a block over time based on the uplink channel data, such as the number of streams to be multiplexed. Thus, the provided adaptive uplink pilot multiplexing schemes provide flexible uplink pilot allocation schemes while maintaining single carrier waveform for improved transmit power efficiency and orthogonality of pilots within blocks for improve channel estimation and suppression of interference.

摘要： Multi-carrier point-to-multi-point CDMA system implementation reduces hardware changes in legacy single-carrier systems. The number of common downlink channels, such as timing/synchronization and paging channels, is reduced by designating an anchor carrier for transmitting these channels. Procedures for adding carriers and carrier acquisition are simplified through common carrier timing, signaling by the network to the user equipment (UE) of timing offsets and scrambling code selection, and other measures. Channel reuse is employed to minimize changes in asymmetric systems with different numbers of uplink and downlink carriers. Channel Quality Indicator (CQI) field is divided into multiple subfields to enable transmission of multiple CQIs and ACK/NACK indicators on one uplink carrier. Joint and separate scheduling schemes are shown for concurrent scheduling of a data stream transmission to a UE via multiple downlink carriers.

摘要： Providing for improved error control signaling in wireless communications is disclosed herein. By way of example, multiple transmissions can be conducted for a HARQ process prior to a scheduled feedback signal on the HARQ process, causing a receiving device to combine the multiple transmissions, rather than treat them as separate transmissions. In this manner, multiple transmissions can be employed to increase overall receive energy, without violating maximum transmit power constraints in a wireless communication. Further, these multiple transmissions can be configured based on prevailing signal strength at the receiving device, or based on processing capabilities of the receiving device, providing flexible protocols that can accommodate advanced as well as legacy UEs in wide range of wireless conditions.

摘要： Techniques for transmitting random access signaling for system access are described. In an aspect, random access signaling may be sent based on at least one transmission parameter having different values for different user equipment (UE) classes. At least one parameter value may be determined based on a particular UE class, and the random access signaling may be sent based on the determined parameter value(s). The random access signaling may be a random access preamble, and the at least one transmission parameter may include a target SNR, a backoff time, and/or a power ramp. The random access preamble may then be sent based on a target SNR value, a power ramp value, and/or a backoff time value for the particular UE class. In another aspect, a message for system access may be sent based on a power control correction received in a random access response for the random access preamble.

摘要： Systems and methodologies are described that facilitate conveying information utilizing a constant phase offset on Primary Synchronization Signal (PSS). In general, the subject innovation can employ a fixed set of beams and phases in which a PSS and a Secondary Synchronization Signal (SSS) can be transmitted with the fixed set of beams and phases. Furthermore, the phase offset for PSS and SSS can be the same such that legacy user equipment is unaffected or aware of such transmissions.

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： 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 selecting frequency for transmitting control channel format indicator (CCFI) data such to identify a related cell. In one example, the CCFI data can be transmitted in an initial portion of frequency (such as an orthogonal frequency division multiplexing (OFDM) symbol) in a time transmit interval (TTI). The CCFI data can be spread across the initial portion of frequency and be shifted to identify the transmitting cell. Additionally, the CCFI data can be scrambled to further identify the cell. The CCFI data can also be utilized to determine structure of subsequent control and/or data channels.
