摘要： Techniques are provided for single carrier optimization. For example, there is provided a method that involves, in a subframe of a radio spectrum, allocating a first set of resource elements (REs) for multimedia broadcast over a single frequency network (MBSFN) transmissions, each symbol corresponding to each RE of the first set having a first cyclic prefix (CP) type.

摘要： Various methods and systems for efficiently performing the blind decoding of downlink signals is described. Several forms of arranging possible CCE combinations are examined and investigated. Based on PDCCH size estimation/information, CCE concatenations that are most likely (of limited sets) can be arrived at. Tree-based concatenations are also devised using largest CCE ordering to align smaller CCE sizes to similar boundaries. By such ordering, the search space for all possible CCE ordering and sizes can be reduced to an efficient tree. Set mapping between possible lnposelstartCCElnposelend/REs are also described using a first set to secondary and tertiary sets. Various other ordering and sorting schemes are also detailed that enable a blind decode of a PDCCH channel to be efficiently performed.

摘要： Systems and methodologies are described that facilitate defining and utilizing hopping patterns to transmit broadband pilot signals in a wireless communications network. Portions of bandwidth can be dedicated to transmitting the broadband pilot data, and patterns can be utilized to hop across frequencies in given time periods to effectively utilize the entire dedicated bandwidth. Moreover, the periodicity for transmitting the data is configurable to allow devices requiring additional scheduling (e.g., high activity devices) to transmit the broadband pilot data more frequently. The hopping patterns can also hop across cyclic shifts of the patterns to provide optimum diversity for transmitting broadband pilot signals.

摘要： Methods and apparatus for performing radio resource management (RRM) measurements in a heterogeneous network (HetNet) are provided in an effort to prevent failure of RRM measurement procedures in a dominant interference scenario. Several alternatives are provided for determining particular resources (e.g., subframes) to use for performing the RRM measurements, wherein the particular resources are based on cooperative resource partitioning between cells of the HetNet, wherein the cells may be of different types (e.g., macro, pico, or femto cells). These alternatives include, for example: (1) intra-frequency or intra-RAT (radio access technology) alternatives, which may involve transmitting resource partitioning information (RPI) in or deriving non-serving cell RPI based on the serving cell's RPI, as well as (2) inter-frequency or inter-RAT alternatives, where the RRM measurements may be performed during a measurement gap.

摘要： Systems and methods for selecting data rates at which to transmit data over a primary uplink in the presence of one or more secondary uplink channels. One embodiment comprises a method including determining probabilities associated with numbers of attempted transmissions of data, determining the number of times pending data transmissions have been attempted, determining probabilities associated with the data transmissions, and allocating power for transmission of the data in a succeeding frame based upon the associated probabilities. In one embodiment, a highest supportable data rate for a primary uplink is initially selected. Then, power is allocated for a minimum set of channels on the primary uplink. Then, power is allocated for pending data transmissions on the secondary uplink. A maximum power level for the transceiver is then adjusted to account for the allocated power, and the highest supportable data rate for the primary uplink is recomputed.

摘要： User equipment (UE) associated with synchronous networks operate in a synchronous mode while UEs associated with asynchronous networks operate in an asynchronous mode. When operating in a synchronous mode, a UE can significantly improve performance of synchronization signal detection, data decoding, and tracking loop management by using the interference cancellation (IC) techniques that are not available in an asynchronous mode of operation. Obtaining synchronization indicators and determining the synchronization status of the current network by UE is disclosed. The determination may be based on the synchronization indicator, whether detected through signal detection, signal measurements, signal analysis, or the like.

摘要： Systems and methodologies are described that facilitate employing periodic closed loop power control corrections in a wireless communication environment. A periodic power control command can be sent over a downlink to control and/or correct an uplink power level employed by an access terminal. Each periodic power control command can be generated based upon an uplink periodic transmission sent from the access terminal. The periodic power control commands can be communicated via a Physical Downlink Control Channel (PDCCH) or in-band signaling. Moreover, access terminals can be grouped to enhance efficiency of downlink transfer of the periodic power control commands. The periodic power control commands can be halted upon access terminal uplink resources being deallocated. For instance, these resources can be deallocated after an inactivity period of the access terminal. Thereafter, the access terminal can initiate random access (e.g., leveraging open loop mechanisms) to resume periodic power control command transmission.
