    Abstract: A base station communicates a positioning reference signal (PRS) to wireless communication devices over a downlink in a wireless communication system by encoding a PRS into a first set of transmission resources, encoding other information into a second set of transmission resources, multiplexing the two sets of resources into a subframe such that the first set of resources is multiplexed into at least a portion of a first set of orthogonal frequency division multiplexed (OFDM) symbols based on an identifier associated with the base station and the second set of resources is multiplexed into a second set of OFDM symbols. Upon receiving the subframe, a wireless communication device determines which set of transmission resources contains the PRS based on the identifier associated with the base station that transmitted the subframe and processes the set of resources containing the PRS to estimate timing (e.g., time of arrival) information.

    Abstract: A mobile device estimates a data symbol from a received signal by using one or more interference cancellation algorithms. For one interference cancellation algorithm, the mobile device calculates (302) a Channel State Information (CSI) of an interfering sector and calculates (304) a CSI of a serving sector at a different time. The mobile device then determines (310) a correction factor to the CSI of the interfering sector by, for example, estimating a Doppler speed and a time difference between a first time interval like a preamble symbol and a second time interval like any symbol of interest in the data zone. Using the correction factor, the mobile device updates outdated interference information. The mobile device can cancel interference in the received signal distorted by co-channel interference by using the updated interference information. Also, the mobile device can be configured to combine results of multiple interference cancellation algorithms based on the applicability of the individual interference cancellation algorithms in particular scenarios.

    Abstract: A method and apparatus for performing mobility measurement in a communication network (100) is described. The method comprises of receiving a subframe sequence pattern from a node in the communication network (100). The subframe sequence pattern indicates types of subframes being transmitted by a neighboring cell node (104) in a neighboring cell (112). The method includes receiving a subframe from a sequence of subframes transmitted by the neighboring cell node (104) in the neighboring cell (112), and determining that the received subframe is a multicast subframe based on the subframe sequence pattern. The method then includes performing a single cell-specific reference symbol measurement in response to determining that the received subframe is the multicast subframe.

    Abstract: The present disclosure describes a method and apparatus for transmit power calibration in a frequency division multiplexed wireless system (100). The method may include receiving (315) an uplink scheduling grant at a user equipment (120), establishing (320) a desired power level based on at least the uplink scheduling grant, and setting (325) hardware power settings based on the desired power level.
