摘要： The present application discloses a method and system for transmitting a Broadcast/Multicast Service (MBMS), which is used for solving the problem that macro cell coverage of the MBMS and macro diversity combining of multi-cells cannot be implemented efficiently based on a frame structure of the existing Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system in prior art. The method includes: mapping a channel estimation code and data symbols of a Broadcast/Multicast Service to a resource unit, wherein the channel estimation code is mapped in front of the data symbols in a signal frame at a time slot for all services or a time slot for the MBMS; and transmitting the resource unit. Using the present application, efficiency and performance of transmitting a MBMS are improved, and the multi-cells combining of the MBMS and deployment of the MBMS with a macro cell mechanism are implemented efficiently.

摘要： The present invention discloses a method for processing uplink signal. In this method, when a random access channel of a cell where a user equipment (UE) locates is within an uplink pilot timeslot, the UE determining whether there is a conflict between the random access channel and time-frequency position of an uplink channel quality sounding pilot of the UE; and if there is a conflict, the uplink channel quality sounding pilot will not be transmitted by the UE within the uplink pilot timeslot. The present invention also discloses a system and apparatus for processing uplink signal. By applying the method, system and apparatus of the present invention, the interference to detection performance of the random access channel caused by the uplink channel quality sounding pilot will be avoided, thereby increasing the detection performance of the random access channel.
