摘要： Certain aspects of the present disclosure propose methods for reporting information such as a maximum power spectral density to a serving access point after receiving overload indicators from one or more neighboring access points. The reported information may be multiplexed with other information (e.g., Channel Quality Indicator (CQI), Precoding Matrix Index (PMI), rank indication (RI) or acknowledgement (ACK)/negative acknowledgment (NACK) message for downlink data channel) before transmission to the serving access point. In addition, the information may be transmitted in a medium access control (MAC) packet data unit (PDU).

摘要： Techniques for deriving channel estimates with different channel estimation filters are described. In one scheme, a filter selection metric is determined for a signal to be recovered, a channel estimation filter is selected based on the filter selection metric, and a channel estimate is derived with the selected channel estimation filter. In another scheme, a first channel estimate is derived with a first channel estimation filter having a first filter response, a first signal is recovered with the first channel estimate, and interference due to the first signal is estimated and removed. A second channel estimate is derived with a second channel estimation filter having a second filter response that is different from the first filter response.

摘要： Systems and methodologies are described that facilitate efficiently indicating parameter(s) associated with a base station utilizing synchronization signals in a wireless communication environment. For instance, relative locations of a PSC and a SSC in a radio frame can be a function of a parameter. Further, a PSC sequence utilized to generate PSCs can be selected based upon a parameter. Moreover, inclusion or exclusion of PSCs from a radio frame can be a function of a parameter. Additionally or alternatively, pseudo random sequence mappings (e.g., to cell IDs, tone locations) can be a function of a parameter. Example parameters can be whether the base station is part of a TDD or a FDD system, whether the radio frame employs FS1 or FS2, whether the base station is associated with a macro or a femto cell, or whether the base station is associated with a unicast or a multicast system.

摘要： Downlink schemes are disclosed for a cooperative user equipment (UE) with joint baseband processing. UEs may establish a cooperative UE unit with one or more neighboring UEs, where one of the UEs operates as the primary UE. The participating UEs of the cooperative UE unit determine a downlink transmission scheme for the cooperative transmissions from a serving base station and receive cooperative transmissions of one or more transport blocks from the serving base station according to the downlink transmission scheme. The secondary UEs of the cooperative UE unit generate and transmit cooperative process data to the primary UE, where the cooperative process data is based on the receipt of the cooperative transmissions by the secondary UEs. The primary UE processes its received cooperative transmission along with the cooperative process data to decode the one or more transport blocks. Other aspects and features are also claimed and described.

摘要： Systems and methodologies are described that facilitate controlling interference in a heterogeneous wireless communication environment. A Physical Broadcast Channel (PBCH) transmission from an interfering base station can be punctured based upon a puncturing pattern as a function of a cell identifier (ID) and a transmit time. Puncturing can be effectuated by applying power control. Thus, a punctured symbol or subframe can have a reduced transmit power or a transmit power set to zero. Further, the puncturing pattern can be defined on a subframe basis or on a symbol basis.

摘要： Providing for modified rate-matching of modulated data to convey mobile network system information is described herein. By way of example, a rate-matching state, such as a data offset, can be introduced into a coded data stream that is modulated to resources of a wireless signal. The state can further be correlated to a state of the network system, such as transmit antenna configuration. Terminals receiving the wireless signal can analyze the signal to identify the rate-matching state and obtain the correlated network system state. Components of the terminal can then be configured according to the particular network system state, resulting in improving access point detection, and in some cases improved channel throughput and reliability.
