摘要:
A contention-based uplink data transmission method, apparatus and system are provided. The method may include that: a main control node in a communication system receives data transmitted via uplink contention transmission resources, and decodes the data, wherein the uplink contention transmission resources are uplink transmission resources which the main control node allocates to a plurality of terminal nodes in the communication system and via which the plurality of terminal nodes transmits data in a contention-based way; and the main control node sends reception status information to each terminal node transmitting the data via the uplink contention transmission resources, wherein the reception status information reflects whether the data transmitted from each terminal node has been decoded successfully.

A method and device for carrier management in a carrier aggregation system, includes signaling which carries an additional carrier measurement indication sent to a User Equipment (UE); a measurement report received from the UE; when the downlink traffic of the UE increases, if the recorded carriers in the current downlink carrier set of the UE can not meet the requirement of the downlink traffic data rate, according to the additional carrier measurement report, at least one additional carrier is configured and activated, and the UE is notified to perform the corresponding configuration operation. In addition, according to the measurement result and the change in the downlink traffic of the UE, the base station can also perform the deactivation, activation replacement and removal of the additional carrier for the user, and notify the UE to perform the corresponding configuration operations.
摘要:
A control method for a radio communication system, wherein a first apparatus transmits a radio signal used to select a radio resource to a second apparatus and when the second apparatus receives a radio signal for requesting allocation of a radio resource from the first apparatus, the second apparatus selects a radio resource to be allocated to the first apparatus based on a radio signal used to select the radio resource and transmits information of the selected radio resource to the first apparatus Consequently, the first apparatus transmits transmission data by using the radio resource specified by the information. The method includes regulating transmission of the radio signal used to select the radio resource to be allocated when the first apparatus receives a particular signal from the second apparatus.
摘要:
A backhaul is configured in such a manner that a HARQ process in which a HARQ on an upstream access link is incapable of being partly or entirely performed is limited to a particular one of a plurality of HARQ processes. As a result, complexity of scheduling is reduced and efficiency of the access link is improved.
摘要:
A radio communication apparatus selectively performs one of a first transmission method using for data transmission a radio resource which is assigned by a radio communication apparatus and which can be used on a contention basis by a plurality of radio communication apparatus and a second transmission method involving random access. Alternatively, the radio communication apparatus selectively performs one of the first transmission method and a third transmission method involving a request made to the radio communication apparatus to assign a radio resource for data transmission.
摘要:
A mobile communication system, that includes a buffer storing packet data to be sent; and a controller configured for discarding the packet data according to a value of a timer corresponding to the packet data, maintaining the value of the timer corresponding to the packet data when a handover is performed without restarting or resetting the value of the timer, wherein the discarding further includes discarding the corresponding packet data when the value of the timer reaches a given value.
摘要:
A method for random access in a wireless communication system communicating between a base station and a wireless terminal, the method consists of: at the wireless terminal, selecting first information used for first random access or second information used for second random access and performing a data communication with the base station during or after the completion of random access using selected information.
摘要:
A method used in a radio communication system including a first radio base station, a second radio base station that communicates with the first radio base station, a relay station which communicates with the second radio base station via the first radio base station, and a mobile station, the method transmits a request, by the second radio base station, for requesting the first radio base station to communicate with the relay station for the second radio base station and communicating, by the requested first radio base station, with the relay station for the second radio base station and transmits a communication result to the second radio base station.
摘要:
In response to receiving second transmission timing adjustment information during connection processing while the user equipment is performing the connection processing to the base station based on first transmission timing adjustment information, the first transmission timing adjustment information is applied to transmission timing adjustment for transmission processing until a valid term of the first transmission timing adjustment information; and the second transmission timing adjustment information is applied to transmission timing adjustment for transmission processing after the valid term of the first transmission timing adjustment information.
摘要:
In the event of detecting first information used for first random access and second information used for second random access, the second information being received from the base station unit, a wireless terminal selects one between the first information and the second information. Thereby, either one of the random accesses can be selectively performed, efficiently using resources such as signatures used for random access.
