    Abstract: PROBLEM TO BE SOLVED: To provide techniques for supporting MIMO transmission.SOLUTION: User equipment (UE) is classified into a first group of UE to be scheduled individually and a second group of UE that can be scheduled together (312). The classification is based upon the number of transmit and receive antennas, sector loading, data requirements, long-term channel statistics, and the number of pieces of UE. Channel quality indicator (CQI) information received from the UE is interpreted in different manners depending on the groups to which the UE belong. For MIMO transmission, single UE is selected at a time from the first group (314), or multiple UE is selected at a time from the second group (316). A MIMO transmission is sent to single UE in the first group or multiple UE in the second group, at rates selected based upon the CQI information (318).

    Abstract: PROBLEM TO BE SOLVED: To facilitate efficiently indicating parameter(s) associated with a base station utilizing synchronization signals in a wireless communication environment.SOLUTION: Relative locations of a PSC and an SSC in a radio frame can be a function of a parameter. A PSC sequence utilized to generate PSCs can be selected based upon a parameter. Inclusion or exclusion of PSCs from a radio frame can be a function of a parameter.

Parameters indicate whether the base station is part of a TDD or FDD system, whether the radio frame employs FS1 or FS2, whether the base station is associated with a macro or femto cell, or whether the base station is associated with a unicast or multicast system.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for sending control information in a communication system.SOLUTION: Control information may be sent in a first frequency location (e.g., a first set of subcarriers) if data is not being sent, and in a second frequency location (e.g., a second set of subcarriers) if data is being sent.

In the first scheme, a CAZAC sequence may be modulated with each modulation symbol for control information to obtain a corresponding modulated CAZAC sequence, which may be sent on the first set of subcarriers. In the second scheme, modulation symbols for control information may be combined with modulation symbols for data, transformed to frequency domain, and mapped to the second set of subcarriers.

    Abstract: PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate evaluating and utilizing timing updates in a wireless communications network.SOLUTION: A base station can transmit timing adjustment commands to mobile devices as needed as opposed to a periodic timing update where timing adjustment commands are always sent within a certain period. However, the mobile devices need to stay awake to monitor the timing adjustment message, resulting in high power consumption. On the other hand, with periodic update, the mobile devices wake up to check whether there is a timing adjustment for itself and, if not, return to a sleep mode. With the proposed method, a mobile device can sleep for a period of time to check timing adjustment commands upon waking.

    Abstract: PROBLEM TO BE SOLVED: To provide hopping structures for broadband pilot signals.SOLUTION: 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.
