摘要： Systems, methods, and apparatuses for sounding reference signal (SRS) management in carrier aggregation (CA) are described. A user equipment (UE) may be scheduled for overlapping (e.g., concurrent) transmissions of SRS and uplink control or data on different cells of a CA configuration. In some cases, the SRS transmission may be dropped (e.g., the UE may refrain from transmitting a scheduled SRS). While in some cases, the UE may transmit both SRS and another uplink message in overlapping time intervals on different cells (e.g., SRS may be transmitted concurrently with another uplink message). A determination of whether to transmit or drop SRS may be based on whether the different cells have different cyclic prefix (CP) lengths or on whether the SRS is scheduled to be transmitted in a special subframe of a time division duplexing (TDD) configuration, for example.

摘要： This application provides a control information transmission method, a base station, and a terminal. The method includes: extracting a radio resource from a preset resource block set, and sending control information in a first time period by using the radio resource. The base station includes a processor and a transmitter. The processor is configured to extract a radio resource from a preset resource block set, and the transmitter is configured to send control information in a first time period by using the radio resource. According to the control information transmission method provided in this application, the base station can send the control information in any time period, and the terminal can receive the control information in any time period, thereby shortening a time interval between two control information transmissions.

摘要： Embodiments of the invention provide an OFDMA contention method and an access point, relating to computer and communication technologies field. The OFDMA contention method includes: receiving, by an access point, a contention request frame transmitted by a station over a subchannel, and judging whether a sum of a number of stations succeeding in a contention in a current channel contention period and a number of stations succeeding in a historic contention is minor than a preset threshold; if yes, triggering the station to enter a next channel contention period, and repeatedly executing the steps of the receiving, by the access point, the contention request frame transmitted by the station over the subchannel, and the judging whether the sum of the number of stations succeeding in the contention in the current channel contention period and the number of stations succeeding in the historic contention is minor than a preset threshold, until a number of stations succeeding in contentions is greater than or equal to the preset threshold. The OFDMA contention method and the access point, can go on initiating a contention when the number of stations succeeding in an initial contention is minor than a certain threshold, to increase the number of the stations succeeding in contentions, thereby improving the throughput of an OFDMA system.

摘要： Methods for UE measurement enhancement in an adaptive TDD configuration network are proposed. In a first solution, the network provides an adaptive TDD indicator to the UE. In a second solution, the network provides an instantaneous TDD configuration to the UE. In a third solution, multiple TDD configurations are grouped as one TDD group, and the network adapts TDD configurations within the same TDD group. In a fourth solution, the network broadcasts a TDD reference configuration in SIB1, and adapts to another TDD configuration with DL super set constraint, i.e., the DL subframes of the other TDD configuration form a super set of the DL subframes of the broadcasted TDD reference configuration.

摘要： The invention relates to a random access procedure for use in a mobile communication system. Furthermore, the invention also provides a mobile terminal and a base station that as suitably adapted to perform the random access procedure as well as the definition of a special format of a random access response message signalled during the random access procedure. To suggest a random access procedure that allows more information to be conveyed in the fist scheduled transmission of the random access procedure, the invention proposes a random access procedure for use in a mobile communication system, wherein a base station transmits a random access response in response to receiving a random access preamble from a mobile terminal, wherein the random access response message comprises a grant for a scheduled transmission by the mobile terminal and an indication on the uplink transmission mode for the scheduled transmission.
