20100172433 | ENCODING METHOD AND APPARATUS - An encoding method and apparatus are provided. In the encoding method: encoding input information bits with an encoding matrix G and a linear combination formula. The encoding matrix G is an encoding matrix obtained by performing row permutation on an encoding matrix H having a plurality of successive zeroes in one or more columns of the encoding matrix H. Encoding control information with the encoding matrix provided by aspects of the present disclosure, each bit of the control information is distributed on all encoded output bits as uniformly as possible. Thereby, the bits of the control information obtain sufficient frequency diversity and time diversity after channel mapping, so as to improve transmission performance of the control information effectively. | 07-08-2010 |

20140321392 | METHOD FOR DETERMINING UPLINK TRANSMISSION POWER AND USER EQUIPMENT - The present invention provides a method for determining an uplink transmission power and a user equipment. In the present invention, a user equipment determines an overlap between an uplink channel of a cell in a current subframe and an uplink channel of another cell in an adjacent subframe, the cell being carrier aggregation with the another cell, so that the user equipment can determine transmission power of a PUSCH of the cell in the current subframe and the another cell in the current subframe, the another cell being carrier aggregation with the cell. As a result, the problem that the uplink power control performed by the user equipment according to the prior art is not accurate is solved and thus the uplink data transmitting quality is improved. | 10-30-2014 |
20150103798 | METHOD FOR DETERMINING A TRANSMISSION FORM, TERMINAL AND BASE STATION - A method for determining a transmission form, a terminal and a base station are provided. Embodiments of present invention acquire a CQI index by the terminal, and transmit the CQI index to the base station, wherein, there is a one-to-one correspondence between the CQI index and a transmission form, and the transmission form comprises: an aggregation level of a control channel; or, the aggregation level of the control channel and a modulation mode of the control channel, and the processing of the base station on the reported CSI is different from that in the prior art, which reduces the invalid processing of the base station, can avoid the problem that much invalid processing of the base station on the CSI processing of PDSCH in the prior art, or, the base station cannot use the reported CSI information about the PDSCH, and can improve the transmission performance of the system effectively. | 04-16-2015 |
20150195814 | BROADCAST MESSAGE TRANSMISSION METHOD, BASE STATION AND USER EQUIPMENT - The present invention provides a broadcast message transmission method, a base station and user equipment. The method includes: determining a resource position of a broadcast channel, wherein the broadcast channel occupies M physical resource blocks (PRBs) among m PRBs of a frequency band center of a carrier, m and M are positive integers, M is not greater than m, and m is not greater than the number of the PRBs corresponding to the system bandwidth; mapping the broadcast channel on the resource position; and sending a broadcast message through the broadcast channel. In the embodiments of the present invention, since the broadcast channel occupies M PRBs among m PRBs of a frequency band center of a carrier, by mapping the broadcast channel on the resource position and sending a broadcast message through the broadcast channel, the resource utilization rate of the carrier may be improved. | 07-09-2015 |
