Publication number: 20080095104Abstract: Herein described are at least a method and a system for transmitting high speed wireless data from a first communication device to a second communication device. The method comprises using a first physical layer for transmitting management data or control signals between the first and second devices. In one embodiment, the management data may be used to authenticate and assign an appropriate wireless communication channel between the first and second device. The wireless communication channel is established by implementing a second physical layer in each of the first and second devices. The wireless communication channel may be used to transmit the high speed wireless data. The system comprises a first communication device and a second communication device wherein each of the first communication device and the second communication device utilizes a first physical layer and a second physical layer.Type: ApplicationFiled: October 20, 2006Publication date: April 24, 2008Inventor: Christopher James Hansen

Publication number: 20080095106Abstract: Techniques for sending control information on a variable control channel are described. Different structures for mapping control information to control channel resources may be used depending on various factors such as operating configuration, the available resources for the control channel, the type(s) of control information being sent, the amount of control information being sent for each type, whether or not data is being sent, etc. In one design, at least one type of control information being sent may be determined and may comprise channel quality indicator (CQI) information, acknowledgement (ACK) information, and/or other types of control information. A structure of the control channel may be determined based on operating configuration (e.g., system configuration such as asymmetry of downlink and uplink allocations) and/or other factors. The at least one type of control information may be mapped to the resources for the control channel based on the structure.Type: ApplicationFiled: July 23, 2007Publication date: April 24, 2008Inventors: Durga Malladi, Serge Willenegger

Publication number: 20080095107Abstract: Link capacity in a wireless medium is assigned by receiving at least one capacity request; and controlling the wireless link capacity based on at least the received capacity request. Link capacity is altered by reading priority information; creating a capacity request from the priority information read; transmitting the capacity request; receiving link configuration data; and configuring a wireless link to conform to the received allocation of link capacity. Link capacity is controlled by extracting the origin and priority of one or more packets received over the shared wireless medium; selecting the link capacity for one or more wireless links based at least in part on the extracted origin and priority of the one or more packets received, higher capacities are selected for origins from which higher priority packets are received; and transmitting the selected link capacity to the one or more wireless links.Type: ApplicationFiled: August 22, 2007Publication date: April 24, 2008Applicant: THE BOEING COMPANYInventor: Brian J.

Publication number: 20080095108Abstract: Techniques for transmitting synchronization signals to assist user equipments (UEs) perform cell searches are described. In one design, a base station for a cell may generate and transmit a primary synchronization signal and a secondary synchronization signal, which may be used by the UEs for initial cell search at power up. The base station may also generate and transmit one or more beacon signals, which may be used by the UEs for neighbor cell search to detect for neighbor cells. The number of beacon signals to transmit and the set of subcarriers usable for each beacon signal may be determined based on the system bandwidth. Each beacon signal may be mapped to one subcarrier in the set of subcarriers in each beacon symbol period. This one subcarrier may be determined based on a beacon hopping pattern or a beacon code and may be dependent on a cell identifier (ID).Type: ApplicationFiled: September 11, 2007Publication date: April 24, 2008Inventors: Durga MALLADI, Juan MONTOJO, Junyi LI

Publication number: 20080095110Abstract: System(s) and method(s) are provided for transmitting data code symbols and control code symbols spanning disparate transmission time intervals in the uplink. Data and control symbols that overlap in time-domain within a transmission time interval are multiplexed and transmitted employing resources scheduled for data transmission, whereas data and control code symbols that are not multiplexed are transmitted in respective allocated resources. Multiplexing in conjunction with localized and distributed resource scheduling preserves the single-carrier characteristics of a single-carrier frequency division multiple access system.Type: ApplicationFiled: August 29, 2007Publication date: April 24, 2008Inventors: Juan Montojo, Durga Malladi, Serge Willenegger
