Implementations describe a user equipment, an access node, and to methods for a user equipment and for an access node. The user equipment includes a receiver configured to receive a downlink control signal (CTRLS) over a downlink control channel (PDCCH) from an access node. The user device also includes a processor configured to, when the user equipment is in a Radio Resource Control (RRC) connected mode, switch on the receiver at a time point (t.sub.start.sub._.sub.symbol) when a symbol comprising the downlink control signal (CTRLS) starts in time domain. The processor is further configured to switch off the receiver at a time point (t.sub.end.sub._.sub.symbol) when the symbol comprising the downlink control channel (CTRLS) ends in time domain.

UPLINK FEEDBACK METHODS FOR OPERATING WITH A LARGE NUMBER OF CARRIERS

A method and apparatus for uplink feedback for operating with a large number of carriers are disclosed herein. A method in a wireless transmit/receive unit (WTRU) includes receiving a plurality of transport blocks over a set of a plurality of configured carriers, generating hybrid automatic repeat request (HARQ)-acknowledgment (ACK) feedback for the transport blocks and determining a number of HARQ-ACK feedback bits to use for the HARQ-ACK feedback. Further, the WTRU may apply, to the HARQ-ACK feedback bits, Reed-Muller coding on a condition that the number of HARQ-ACK feedback bits is less than or equal to a threshold or convolutional coding on a condition that the number of HARQ-ACK feedback bits is greater than a threshold. The WTRU may then transmit the encoded HARQ-ACK feedback bits. In addition, the WTRU may conditionally append cyclic redundancy check (CRC) bits onto the HARQ-ACK feedback bits, and encode and transmit the CRC bits.

Method for monitoring paging message, mobile terminal and server

An embodiment of the present disclosure provides a method for monitoring a paging message, a mobile terminal, and a server. The method for monitoring the paging message is operable by a mobile terminal and includes: detecting whether the mobile terminal is in a connected state where the mobile terminal is connected with a wireless access device accessing the Internet; when the mobile terminal is in the connected state where the mobile terminal is connected with the wireless access device, monitoring the paging message according to a first paging cycle; when otherwise, monitoring the paging message according to a second paging cycle, wherein the first paging cycle is longer than the second paging cycle, and the second paging cycle is equal to a cycle according to which a core network transmits the paging message.

Method and apparatus for maintaining uplink synchronization and reducing battery power consumption

A Node-B sends a polling message to a wireless transmit/receive unit (WTRU). The WTRU sends an uplink synchronization burst in response to the polling message without contention. The Node-B estimates an uplink timing shift based on the synchronization burst and sends an uplink timing adjustment command to the WTRU. The WTRU then adjusts uplink timing based on the uplink timing adjustment command. Alternatively, the Node-B may send a scheduling message for uplink synchronization to the WTRU. The WTRU may send a synchronization burst based on the scheduling message. Alternatively, the WTRU may perform contention-based uplink synchronization after receiving a synchronization request from the Node-B. The WTRU may enter an idle state instead of performing a handover to a new cell when the WTRU moves to the new cell. A discontinuous reception (DRX) interval for the WTRU may be set based on activity of the WTRU.

An access point generates a beacon frame that carries a trigger frame information element comprising sending information of a trigger frame for indicating a sending period of the trigger frame; and sends the beacon frame. In this case, the station switches to an active state, and receives the trigger frame by listening to the channel, and the station performs uplink transmission according to indication of the trigger frame after receiving the trigger frame. In this way, when signaling overheads are not increased and reliability is ensured, a station can learn of a sending time of a trigger frame, and the station remains in a receiving state in an appropriate period of time.
