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.

摘要： Techniques for accessing a wireless communication system are described. A user equipment (UE) sends a random access preamble for system access. The random access preamble may include a random identifier (ID), a channel quality indicator (CQI), etc. The UE may randomly select the random ID or may be assigned this random ID. The UE receives a random access response from a base station. The random access response may include control channel resources (e.g., CQI and PC resources), uplink resources, and/or control information (e.g., timing advance and PC correction) for the UE. The random access response may be sent in two parts using two messages. A first message may be sent on a control channel and may include identification information and possibly other information. A second message may be sent on a shared data channel and may include remaining information for the random access response.

摘要： System(s) and method(s) are provided for inter-cell interference management in a wireless communication system. A base station perform interference management by conveying and receiving load indicator messages over a backhaul communication link to disparate neighboring base stations that serve interfering mobile stations. Reporting of load indicators takes place according to a reporting policy that is event-based, and accounts for variations of interference metrics over available time-frequency resources. Communication with neighboring base stations is limited to a monitoring interference set, which can be determined statically, according to deployment characteristics of a wireless network, or the set can be adjusted dynamically according to a set of received UL signals or a set of DL CQI measurement reports. Reporting policy and interference set can be autonomously adapted to optimize backhaul traffic as well as interference control.

摘要： Systems and methodologies are described that facilitate adaptively communicating data to wireless devices. An access point can precode a dedicated reference signal (DRS) for transmitting to a wireless device, and the wireless device can receive the precoded DRS. The wireless device can determine the precoder by estimating a channel of the DRS and can provide channel condition feedback to the access point. The access point can create data signals including a single or a burst of data transmissions according to the feedback and can precode the data signals using the same precoder. The wireless device can additionally decode the data signals using the precoder. Moreover, the access point can cycle through precoders according to a patterned, random, pseudo-random, and/or similar sequence.

摘要： Systems and methodologies are described that facilitate utilizing power control preambles with closed loop power control techniques in a wireless communication environment. An uplink grant can be transferred over a downlink (e.g., a first uplink grant after uplink inactivity), and a power control preamble can be sent over an uplink in response to the uplink grant. According to an example, transmission of the power control preamble can be explicitly scheduled and/or implicitly scheduled. The power control preamble can be transmitted at a power level determined by an access terminal utilizing an open loop power control mechanism. A base station can analyze the power control preamble and generate a power control command based thereupon to correct the power level employed by the access terminal. The access terminal can thereafter utilize the power control command to adjust the power level for uplink data transmission.

摘要： Techniques for dynamically mapping assigned resources to physical resources are described herein. In one design, a resource assigned for communication may be mapped to a first physical resource based on a first mapping function and to a second physical resource based on a second mapping function. The assigned resource may be configurable for hopping or no hopping. The first mapping function may be a transparent function or may map consecutive input indices to non-consecutive output indices. The second mapping function may be equal to an output of the first mapping function plus an offset defined by a step size and a hop value. The hop value may be configurable for the assigned resource and may be conveyed in a resource assignment. The hop value may be set to a first value to indicate no hopping or to a second value to indicate hopping by the step size.

摘要： Techniques for transmitting traffic data and control information in a wireless communication system are described. In an aspect, traffic data and control information may be multiplexed at a coded data level. A user equipment (UE) may encode traffic data to obtain coded traffic data, encode control information to obtain coded control data, multiplex the coded traffic data and the coded control data, modulate the multiplexed data, and generate SC-FDMA symbols. In another aspect, traffic data and control information may be multiplexed at a modulation symbol level. The UE may encode and modulate traffic data to obtain data modulation symbols, encode and modulate control information to obtain control modulation symbols, multiplex the data and control modulation symbols, and generate SC-FDMA symbols. The UE may perform rate matching for traffic data to account for control information. The UE may also perform multiplexing and puncturing for different types of control information.
