摘要： A basic idea is to determine scheduling priorities of users based on information representative of experienced end-to-end quality of user communication in an overall network, and allocate communication resources in a wireless sub-network (100; 200) of the overall network to users based on the determined scheduling priorities. For example, the sub-network (100; 200) may be a wireless access network within an overall network, and end-to-end quality information related to the overall network may then be taken into account in the local scheduling procedure in the access network.

摘要： Repetition coding is performed on control channel information to generate a plurality of encoded control channel signals, which are then transmitted using time-frequency resource-element groups. The time-frequency resource-element groups include orthogonal frequency division multiplexing (OFDM) symbols in a time domain and frequency subcarriers in a frequency domain. The plurality of encoded control channel signals are transmitted separately from each other in the frequency domain when one of the OFDM symbols is used for transmitting the plurality of encoded control channel signals. At least two of the plurality of encoded control channel signals are transmitted using one or more resource-element groups and the at least two of the plurality of encoded control channel signals are transmitted separately from each other in the frequency domain when two of the OFDM symbols are used for transmitting.

摘要： A PDCP status report can be transmitted with reduced radio resources by transmitting the reception success or failure of a series of PDCP service data units (SDUs) in the form of a bitmap when configuring the PDCP status report. A PDCP control packet data unit (PDU) is generated to communicate a status report to a transmitting node for one or more PDCP SDUs transmitted from the transmitting node. The PDCP control PDU includes a data/control (D/C) bit field to indicate the PDCP control PDU is a control PDU, a control PDU type field to indicate a type of corresponding control information, a sequence number field to indicate a first missing PDCP SDU, and a bitmap field for a variable length bitmap. A bit in the variable length bitmap indicates whether a corresponding one of the one or more PDCP SDUs has been successfully been received.

摘要： A mobile terminal performs a random access procedure with a network that includes transmitting to the network a random access preamble directly allocated to the mobile terminal by the network and receiving a random access response from the network in response to transmission of the random access preamble. The terminal performs a discontinuous reception (DRX) operation that controls how the mobile terminal monitors a physical downlink control channel (PDCCH). The DRX operation employs an active time in which the mobile terminal monitors the PDCCH, and the active time includes a time while: (i) an on-duration timer or a DRX Inactivity timer or a DRX retransmission timer or a contention resolution timer is operating, (ii) a scheduling request procedure is pending, (iii) an uplink grant for a retransmission can occur, or (iv) the PDCCH indicating a new transmission addressed to a Cell-Radio Network Temporary Identifier (C-RNTI) of the mobile terminal has not yet been received after successful reception of the random access response.

摘要： Scheduling requests are transmitted from a mobile terminal to a base station. The mobile sends a first scheduling request to the base station, the first scheduling request being associated with first data to be transmitted to the base station. The mobile receives a scheduling grant from the base station in response to the first scheduling request and transmits a buffer status report to the base station in response to receiving the scheduling grant. An HARQ acknowledgment for the buffer status report is received. Second data is received for transmission to the base station while at least some of the first data is waiting to be transmitted to the base station. A change in a buffer status of the mobile terminal is detected indicating that the second data has higher priority than the first data. The mobile transmits a second subsequent scheduling request to the base station in response to the change in buffer status.

摘要： A method for transmitting uplink signals, which include ACK/NACK signals, control signals other than the ACK/NACK signals, and data signals, is disclosed. The method comprises serially multiplexing the control signals and the data signals; sequentially mapping the multiplexed signals within a specific resource region in accordance with a time-first mapping method, the specific resource region including a plurality of symbols and a plurality of virtual subcarriers; and arranging the ACK/NACK signals at both symbols near symbols to which a reference signal of the plurality of symbols is transmitted. Thus, the uplink signals can be transmitted to improve receiving reliability of signals having high priority.

摘要： A status report transmission of the PDCP layer for a PDCP status report can reduce radio resources by transmitting the reception success or failure of a series of PDCP service data units (SDUs) in the form of a bitmap when configuring the PDCP status report for reporting a reception status of PDCP SDUs to another party in the PDCP layer. A PDCP control packet data unit (PDU) is generated to communicate a status report for one or more PDCP SDUs transmitted from a transmitting node. The PDCP control PDU includes a data/control (D/C) bit field to indicate the PDCP control PDU is a control PDU, a control PDU type field to indicate a type of corresponding control information, a sequence number field to indicate a first missing PDCP SDU, and a bitmap field for a variable length bitmap. A specific bit in the variable length bitmap indicates whether a corresponding one of the one or more PDCP SDUs has been successfully been received. The PDCP control PDU is transmitted to the transmitting node.
