摘要： Embodiments of the present invention provide a method and apparatus for determining a starting symbol of a physical downlink shared channel; wherein, a Pico base station transmits information indicating a PDSCH starting symbol of the Pico base station to a Macro base station, the Macro base station transmits the information indicating a PDSCH starting symbol to a terminal, and the terminal determines the PDSCH starting symbol in accordance with the information indicating a PDSCH starting symbol. With the embodiments of the present invention, the terminal within a serving range of the Pico base station resulted from a high offset value will not incorrectly decode a PCFICH due to interference of the Macro base station, thereby making the terminal determine a demarcation symbol between a PDCCH and a PDSCH, further increasing the coverage of the Pico base station, and realizing load balancing of the Macro base station and Pico base station.

摘要： A method for processing in-device coexistence configuration information, apparatus and system. The method includes: notifying, by a source base station to a target base station, first in-device coexistence configuration information configured by the source base station for terminal equipment, when handover from the source base station to the target base station occurs to the terminal equipment. In this way, the source base station may notify the first in-device coexistence configuration information configured by it for the terminal equipment to the target base station; the target base station receives the first in-device coexistence configuration information, determines whether to configure the terminal equipment with in-device coexistence configuration information, and then notifies the source base station of related configuration information via a handover command. With the embodiments of the present disclosure, when handover occurs to the terminal equipment, the in-device coexistence configuration information may be processed effectively.

摘要： The present invention relates to the field of communications, and in particular to a method and apparatus of uplink interference coordination in a heterogeneous network. The method includes: monitoring uplink channel quality of terminal equipment; acquiring an uplink almost blank subframe when uplink interference appears, with terminal equipment in a Macro cell in the uplink almost blank subframe transmitting at reduced transmission power or no transmission power; and scheduling the terminal equipment subjected to uplink interference on the uplink almost blank subframe to perform uplink communication. With the embodiments of the present invention, interference brought by the uplink data transmission of the terminal equipment of the Macro cell to the uplink reception of the terminal equipment of the Pico cell may be avoided, thereby ensuring the uplink channel quality of the terminal equipment in the Pico cell.
