Abstract:
A method for transmitting broadcast service data in a single frequency network including a Radio Network Controller and one or more base stations each with a cell including one or more sectors, the method includes: transmitting, by the Radio Network Controller, broadcast service data and a first transmission time to the base station; and transmitting, by the base station, the broadcast service data to each of its sector after the first transmission time, where the broadcast service data is transmitted to adjacent sectors sharing a common station address at different transmission times. Also, the present invention discloses a system and base station for transmitting broadcast service data in a single frequency network. With this technical solution, the phenomenon of fast fading of received signals in the prior art which occurs at adjacent edge zones of adjacent sectors in the same cell of the single frequency network can be avoided, and thus improving performance of receiving the signals.

Abstract:
Embodiments of the present invention relate to the technical field of wireless communication, and relate particularly to a method, a system, and a device for confirming an uplink-downlink configuration, for use in confirming via interference detection whether or not a cell is capable of conducting independently the uplink-downlink configuration. The method of the embodiments of the present invention comprises: a network side device confirming the receipt of a first RSRP value of a reference signal from a second cell by a first cell, the second cell being an adjacent cell of the first cell (201); on the basis of the first RSRP value, the network side device confirming whether or not the first cell is capable of conducting autonomously the uplink-downlink configuration (202). Measuring the RSRP value to determine whether or not the cell is capable of conducting independently the uplink-downlink configuration allows for the normal operation of a dynamic uplink-downlink configuration, reduced interference between adjacent cells in a dynamic uplink-downlink configuration environment, and improved system efficiency.
Abstract:
Disclosed are a data transmission method, a system and an apparatus, which are used to meet transmission quality requirements of data on multiple kinds of logic channels in the event that multiple kinds of logic channels related to multimedia broadcast multicast service (MBMS) are mapped to the same transmission channel. The data transmission method provided by the present invention includes that: a network side determines multiple kinds of modulation and coding schemes (MCSs) needed to be adopted when multiple kinds of logic channels are mapped to the same transmission channel, and notifies a terminal of correspondence between logic channels and MCSs; using MCSs needed to be adopted, the network side performs modulation and coding for the data on logic channels mapped to the transmission channel, then transmits it to the terminal through the transmission channel.

Abstract:
Disclosed are a method and a device for transmitting an aperiodic SRS in a TDD system. In the technical solution of the present invention,a symbol is defined for the transmission of the aperiodic SRS in a special subframe in the TDD system. This avoids a scenario in which the transmission position of the aperiodic SRS is undefined when a plurality of symbols that can be used to transmit the aperiodic SRS are available in an uplink pilot time slot (UpPTS). The problem of transmitting aperiodic SRS in a TDD system special subframe is thus solved. The modification to corresponding instruction messages is not extensive, and there is no overuse of system resources.
Abstract:
A method, apparatus and system for downlink pilot transmission solve the problem of power differences among OFDM symbols caused by Walsh Codes. The transmission method is that dedicated pilots are transmitted in the manner of code division multiplexing (CDM) or hybrid of CDM and frequency division multiplexing (FDM), wherein the dedicated pilots are configured with orthogonal sequence sets according to a preset frequency-domain granularity and rules on the resources for transmitting the dedicated pilots, and the same orthogonal sequence set is employed for the dedicated pilots in each frequency-domain granularity.
