20120069807 | TRANSMITTER WITH MULTIPLE ANTENNAS AND DATA TRANSMISSION METHOD IN THE TRANSMITTER WITH MULTIPLE ANTENNAS - According to one aspect of the present invention, a multi-antenna transmitter is provided. The transmitter includes: a data block acquiring device for acquiring multiple data streams, wherein each data stream includes data blocks at multiple slots; and a grouping and mapping device for grouping and mapping each data block, wherein the data blocks at the same slot in each data stream are grouped according to the number of the antennas and each group is mapped to one of the antennas respectively, and the different data blocks in the same group are mapped to different sub-bands respectively; and wherein grouping and mapping manners which are not exactly the same are adopted for the data blocks at different slots, and the grouping and mapping manners include data block grouping manners, group-to-antenna mapping manners, and sub-band mapping manners. And the groups of data blocks at the multiple slots are transmitted via the antennas. With the technical solutions of the present invention, a reduced PAPR during data transmission can be achieved while the diversity gain is guaranteed. | 2012-03-22 |
20120069808 | Parameter Feedback in a Wireless Communication System - For using best M method in a mixed subband/miniband environment a Mobile Station Apparatus calculates a metric for sending information corresponding to the metric to a base station. | 2012-03-22 |
20120069809 | METHOD AND DEVICE FOR ALLOCATING COMMON CHANNEL RESOURCES - A resource allocation method and device are provided that can achieve uniform loads on and stable quality of a common channel available to mobile stations having no dedicated channels. A method for allocating common channel resources in a system in which a plurality of first radio communication devices transmit data to a second radio communication device over a common channel, based on first resource allocation information, includes: by the second radio communication device, transmitting second resource allocation information to at least one of the first radio communication devices; and by each of the first radio communication devices, transmitting data to the second radio communication device over the common channel, based on any one of the first resource allocation information and the second resource allocation information. | 2012-03-22 |
20120069810 | METHOD FOR RECEIVING ACK/NACK SIGNAL IN MOBILE COMMUNICATION SYSTEM - A method for transmitting information of resources for use in transmission of ACK/NACK signals in a mobile communication system is disclosed. An example method for receiving ACK/NACK signals in a mobile communication system is also disclosed. When resources for transmission of data and resources for transmission of control information of the data are scheduled through virtual unit resources, the method identifies information of resources for receiving an ACK/NACK signal for transmission data mapped to information of at least one of a virtual unit resource allocated to the transmission data and a virtual unit resource allocated to control information of the transmission data, and receives the ACK/NACK signal for the transmission data through the information of resources for receiving the ACK/NACK signal. | 2012-03-22 |
20120069811 | Method, Apparatus and System for Transmitting Information - A method for transmitting information includes by a NodeB, receiving a message for setting up/reconfiguring a shared Enhanced Dedicated Channel (E-DCH) transmission channel from a Radio Network Controller (RNC); and setting up the shared E-DCH transmission channel according to parameters in the message, and exchanging information with the RNC through an established shared E-DCH transmission bearer. | 2012-03-22 |
