    摘要: 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, and transmitting the subframe. Upon receiving the subframe, a wireless 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.

    摘要: A wireless base unit (102) supporting carrier aggregation determines a truncation time period (159, 169) in order to create a reduced subframe component (154, 164) on an additional component carrier (120) such that the truncated subframe component (154, 164) does not interfere with the control region (171, 172) of a subframe (170, 180) transmitted on an overlapping component carrier (130) by an uncoordinated second base unit (105). The wireless base unit (102) transmits the truncated subframe component (154, 164) and also transmits truncation time period information within a control region (151, 161) of an anchor carrier (110). A remote terminal (104, 108) that supports carrier aggregation searches a control region (151, 161) of a subframe (150, 160) transmitted on the anchor carrier (110) for truncation information and uses the truncation information to determine a boundary of a data region in a subframe component (154, 164) received on the additional component carrier (120).

    摘要: A method and apparatus is provided for transmitting an orthogonal frequency domain multiple access (OFDMA) signal including a synchronization channel signal transmitted within a localized portion of a bandwidth of the OFDMA signal (818), the synchronization channel signal having predetermined time domain symmetry within the localized portion of the bandwidth (816). The synchronization channel signal enables an initial acquisition and cell search method with low computational load which provides OFDMA symbol timing detection and frequency error detection by differential processing of sequence elements of the synchronization channel signal (1112) and frame boundary detection and cell specific information detection (1114) in an OFDMA system supporting multiple system bandwidths, both synchronized and un-synchronized systems, a large cell index and an OFDMA symbol structure with both short and long cyclic prefix length.

    摘要: A method for selective use of control channel element (CCE)-based implicit pointing. The method includes the step of determining whether a number of multiple user elements (UE) within a multi-user multiple-input multiple-output (MU-MIMO) group is greater than the number of resource blocks allocated to the MU-MIMO group. If the number of UEs in the MU-MIMO group is greater than the number of resource blocks allocated to the MU-MIMO group, the method further includes transmitting to each of the UEs of the MU-MIMO group acknowledgements on acknowledgement channels within a first acknowledgement bank and acknowledgements on acknowledgement channels within a second acknowledgement bank. A first portion of the UEs of the MU-MIMO group receives the acknowledgements on the acknowledgement channels within the first acknowledgement bank and a second portion of the UEs of MU-MIMO group receives the acknowledgements on the acknowledgement channels within the second acknowledgement bank.

    摘要: A communication system optimizes cell edge performance and spectral efficiency by a first step of measuring, by the Node B, at least one system performance metric. A next step includes sending, by the Node B, an indicator for the at least one system performance metric measurement. A next step includes receiving the indicator for the at least one system performance metric measurement. A next step includes determining an adaptive power control parameter based on the at least one system performance metric measured by the Node B and system performance metrics measured by at the least one other neighboring Node B. A next step includes using the adaptive power control parameter to update an uplink transmit power level for at least one user equipment served by the Node B.
