摘要:
A method for dividing MBMS control information provided to UEs for an MBMS service into three types and separately transmitting the divided MBMS control information according to their types. The MBMS control information is divided into first MBMS control information that is periodically transmitted, and second MBMS control information that is aperiodically transmitted due to occurrence of an event. The periodically transmitted first MBMS control information is divided into MBMS control information that is transmitted at a first periodic interval and MBMS control information that is transmitted at a second periodic interval. The first periodic interval is shorter than the second periodic interval to enable a UE desiring to receive a particular MBMS service to preferentially receive MBMS status information in advance of MBMS RB information.

An operating method and an apparatus according to data duplicate retransmission in a mobile communication system are provided. A method of a User Equipment (UE) according to data duplicate retransmission in a mobile communication system includes storing a Media Access Control Protocol Data Unit (MAC PDU) received from an Evolved Node B (ENB) in a soft buffer, decoding the MAC PDU, determining whether the decoding is a first successful decoding of data of the corresponding soft buffer, and determining whether to forward the decoded MAC PDU to an upper layer according to the determination result.

Method is provided for communicating with a User Equipment (UE) supporting a High Power Saving Reception Mode (HPSRM) mode by an evolved Node B (eNB) in a wireless communication system. The method includes receiving Discontinuous Reception (DRX) cycle information from a network entity performing mobility management for the UE by the eNB communicating with the UE over a wireless link; and broadcasting system information including the DRX cycle information. The DRX cycle information is set longer than DRX cycle information of a UE non-supporting the HPSRM mode. By doing so, an efficient paging method for an UE operating in the HPSRM mode may be provided.

Methods and apparatus are provided for a User Equipment (UE) to transmit signals in response to the reception of a Downlink Control Information (DCI) format transmitted from a base station of a communication system. The DCI format may provide only the frequency resources for the transmission of signals by the UE, while other parameters associated with the transmission of signals by the UE may be either predetermined or known to the UE through other signaling from the base station. The frequency resources used for the transmission of signals by the UE may be a sub-set of the frequency resources indicated by the DCI format and the determination of this sub-set by the UE may be either deterministic or pseudo-random.
摘要:
An Automatic Repeat reQuest (ARQ) method in a communication system having a protocol layer structure, in which a Layer 2 (L2) transmitter for generating an upper layer packet in a size suitable for transmission over a radio channel and transmitting the upper layer packet to a lower layer, transmits, to a receiver, polling information representative of an indicator for ordering the generation of a status report, and performs packet ARQ according to whether the status report is received within a predetermined time. The method includes determining whether there is a possibility that upper layer data contained in a packet data unit to be transmitted along with the polling information will cause an upper layer message in the opposite direction; and when there is a possibility that the upper layer data will cause an upper layer message, generating polling information ordering a receiver to wait for a predetermined time after receipt of a packet and to transmit an upper layer packet generated for the waiting time along with a status report, including the polling information in the packet data unit, and delivering the packet data unit to the lower layer.

Disclosed is a method of measurement on a home cell/private network cell, by a user equipment (UE), in a mobile communication system, the method including the steps of: transmitting a request message requesting the measurement to a network node, the request message including an indicator instructing at least one of register, join, and use of the home cell/private network cell; receiving a response message corresponding to the request message from the network node, the response message including context information for measurement control of at least one home cell/private network cell accessible by the UE; and selectively executing measurement on the accessible home cell/private network cell by using the context information.
摘要:
A method and a UE apparatus for radio resource management in a mobile communication system. When a discontinuous reception period or an inactivity period of a UE exceeds a threshold, an ENB releases resources for uplink control information transmission allocated to the UE, and the UE recognizes the release of the resources and stops transmitting the uplink control information through the resources. This reduces the explicit reconfiguration procedure through an RRC message, which is otherwise necessary whenever the UE enters a new discontinuous reception mode.
摘要:
A resource allocation method and apparatus for downlink transmission of a base station in a mobile communication system. The base station compares the number Ntx of data transmissions with the number Nper of available persistent resource allocations, and allocates resources by at least one of a persistent resource allocation scheme and a dynamic resource allocation scheme according to the comparison result.

Methods and apparatus are provided for reporting a Power Headroom (PH) of a User Equipment (UE) in a wireless communication system having a plurality of aggregated uplink carriers. The PH is calculated for a Power Headroom Report (PHR)-triggered uplink carrier. A PHR having the PH and an identifier of the PHR-triggered uplink carrier is generated, and the PHR is transmitted to a network. Also, a PHR having the PH is generated, and the PHR is transmitted to a network over one of a plurality of PHR-transmitting uplink carriers configured to correspond to the PHR-triggered uplink carrier.
摘要:
A method for receiving a packet by a terminal in a mobile communication system including a base station providing a packet, and a terminal that discontinuously receives a packet from the base station in Discontinuous Reception (DRX) cycles each having an active period and a sleep period. The packet reception method includes receiving, from the base station, configuration information for a DRX service, including a DRX cycle length; setting, as a starting point of the DRX cycle, a point at which a first packet is received from the base station; receiving a packet from the base station for an active period at the beginning of the starting point; and transitioning to a sleep period and waiting for a next active period.
