20120003941 | Method, Apparatus, and Terminal for Determining Transmission Mode - Embodiments of the present invention disclose a method, an apparatus, and a terminal for determining a transmission mode, which relate to the field of communications technologies and are invented to enable a selection of a transmission mode with lower power consumption for a terminal to reduce the power consumption of the terminal. The method includes: selecting a transmission mode for a terminal according to a network resource condition; judging whether the selected transmission mode matches according to capability information reported by the terminal and if the selected transmission mode matches, setting the transmission mode as a current transmission mode of the terminal. The embodiments of the present invention are mainly applicable to a Long Term Evolution Advance (LTE-A) system. | 01-05-2012 |
20120087439 | Modulation Method and Apparatus - Embodiments of the present invention disclose a modulation method and apparatus. The modulation method includes: processing at least two data blocks, and outputting at least two single-carrier Orthogonal Frequency Division Multiplex (OFDM) signals, where the at least two data blocks include a first data block and a second data block, the at least two single-carrier OFDM signals include a first single-carrier OFDM signal corresponding to the first data block and a second single-carrier OFDM signal corresponding to the second data block, a difference between a carrier center frequency RF | 04-12-2012 |
20130114457 | Method for Reporting Power Headroom Report and User Equipment - The present invention discloses a method for reporting a power headroom report and a user equipment, which are applied in the field of communications. The method includes triggering reporting of a first power headroom report and determining that a condition of sending the first power headroom report is satisfied. The condition of sending the first power headroom report includes a determination that uplink data channel transmission occurs in a current transmission time interval. The first power headroom report is obtained. The first power headroom report includes a first power headroom value that includes a difference between maximum transmitting power of a carrier and a sum of transmitting power of a control channel of the carrier and transmitting power of a data channel of the carrier. | 05-09-2013 |
20140161081 | Method and Apparatus for Power Control - A power control method is provided, which is applicable to the communication field. The method includes: obtaining power headroom information of an aggregated carrier of a User Equipment (UE), where the aggregated carrier includes at least one component carrier group and at least one first carrier, or includes at least one component carrier group, or includes at least two first carriers, the component carrier group includes at least two second carriers, and the first carrier and the second carrier are single carriers; and adjusting transmit power of the aggregated carrier according to the power headroom information. The method enables reporting of power headroom of an aggregated carrier of the UE in a multi-carrier scenario, so that the base station can control the transmitting power of the UE reliably, and therefore, reliability and throughput of the system are improved. | 06-12-2014 |
