Abstract: The present invention provides a method for processing a trunked service attribute, which includes: after a User Equipment (UE) enters a Radio Resource Control Connected (RRC_Connected) state and when a trunked called service is operated on the UE, informing, by the UE, a base station of a trunked service attribute.

Abstract: The present disclosure provides a method for processing a blind detection capability during a trunking group call. According to the method, a terminal may report a trunking identifier and a physical downlink control channel (PDCCH) blind detection capability of the terminal to a base station when the terminal is in a radio resource control_connected (RRC_connected) state and is receiving a called party service of trunking group call.

Abstract: The application provides a method for processing a downlink control channel, including: in a downlink Transmit Time Interval (TTI), when a User Equipment (UE) of a group call in a cell has an individual service to be scheduled, a sender schedules a service of the group call within public space, by using a Group Radio Network Temporary Identifier (G-RNTI), and schedules the individual service within dedicated space by using a Cell Radio Network Temporary Identifier (C-RNTI); in the downlink TTI, when no UE in the group call of the cell has an individual service to be scheduled, the sender schedules the service of the group call within the dedicated space by using the G-RNTI.

Abstract: The present disclosure provides a method for reporting a trunked service attribute. The method includes: when a trunked terminal is to report the trunked service attribute, the trunked terminal reports the trunked service attribute to a base station via the third message MSG3 during a contention based random access procedure or via the first uplink data/signaling packet after obtaining the trunked service attribute. Based on the same concept, the present disclosure also provides a method of receiving a trunked service attribute, and a corresponding trunked terminal, a corresponding base stations and a corresponding system.

Abstract: The present invention provides a method and an apparatus for processing a precoder. The method comprises: step A: a base station determining whether the number of received effective precoders reported by a certain UE is greater than or equal to a threshold a, if so, executing step B, otherwise, executing step D; step B: the base station determining whether each received effective precoder is according to the same number of layers, if so, executing step C, otherwise, executing step D; step C: the base station determining whether a variation speed of each effective precoder is fast, if so, applying a transmit diversity transmission mode to the UE, otherwise, applying a MIMO transmission mode to the UE; and step D: applying the MIMO transmission mode to the UE. Therefore, the present invention can reasonably predict the transmission mode and the precoder that should be employed in the transmission mode at current time for a certain UE.

The method includes: a network allocates the CCE resource according to the CCE aggregation level and the current use information of the CCE resource. Through the present invention, the problem of resource waste in the allocation of idle CCE resource in the related art is solved, thereby achieving the effect of effectively using the idle CCE resource.

Abstract: The disclosure discloses a method and device for reporting channel state information aperiodically. Wherein the method comprises: collecting the channel state information reported by the UE through the configured receiving window; determining the change speed degree of the channel state of the UE according to the criterion for determining a change speed of the channel state information; deciding whether the UE needs to perform aperiodic reporting according to the mapping relationship between the change speed degree of the channel state information and a reporting period adjusting value, and determining timing for the aperiodic reporting if needed.
