A method and system for controlling discontinuous reception (DRX) in a mobile device in a wireless communications network uses autonomous DRX control after initial VoIP traffic setup. If the mobile device transmits a negative-acknowledgement signal (NACK) indicating unsuccessful receipt of a VoIP packet, then it autonomously turns on a predetermined delay time later to receive the retransmission of the VoIP packet. The predetermined delay time is related to the time for the base station to process the NACK and prepare the VoIP packet for retransmission. When the mobile device transmits or retransmits a VoIP packet, reception is deactivated, but is autonomously activated the predetermined delay time later to receive an acknowledgement signal (ACK) or NACK. VoIP packets may be transmitted from the mobile device the predetermined delay time before VoIP packets are transmitted from the base station.

Methods, devices, and systems have various user equipment (UE) for reading multimedia broadcast and multicast service (MBMS) notifications via one or more paging indicators of a Paging Indication Channel (PICH). The paging indicators of the PICH functions as MBMS notification indicators, signaling the relevant UE to read the MBMS point-to-multipoint control channel (MCCH) for MBMS information, and thereby enabling the affected UE to configure themselves to receive the associated multimedia broadcast and/or multicast service.

Multimedia broadcast and multicast service notification in long term evolution

A method and system for controlling discontinuous reception (DRX) in a mobile device in a wireless communications network that supports voice-over-internet-protocol (VoIP) and that uses an automatic repeat-request (ARQ) method, like a hybrid automatic repeat-request (HARQ) method, uses autonomous DRX control after initial VoIP traffic setup. If the mobile device transmits a negative-acknowledgement signal (NACK) indicating unsuccessful receipt of a VoIP packet, then it autonomously turns on a predetermined delay time later to receive the retransmission of the VoIP packet, where the predetermined delay time is related to the time for the base station to process the NACK and prepare the VoIP packet for retransmission. When the mobile device transmits or retransmits a VoIP packet, reception is deactivated, but is autonomously activated the predetermined delay time later to receive an acknowledgement signal (ACK) or NACK. VoIP packets may be transmitted from the mobile device the predetermined delay time before VoIP packets are transmitted from the base station. This alignment allows an ACK or NACK to be transmitted from the base station in the same transmission time interval (TTI) as a VoIP packet.

The invention is a method and system for reliably detecting the start and/or end of silence periods during voice-over-internet-protocol (VoIP) sessions in a wireless communications network. A VoIP session typically includes 'talkspurt' periods, during which VoIP packets are transmitted, and silence periods, during which silence indication (SID) packets are transmitted. Both the base station (eNodeB or eNb) and the mobile device (user equipment or UE) may inspect the packets to identify them as VoIP or SID packets. Alternatively, only the eNB inspects the packets. The eNB then flags the first SID packet after a VoIP packet as the start of a silence period, and flags the first VoIP packet after a SID packet as the end of a silence period. The eNB then modifies the header of the medium access control (MAC) protocol data unit (PDU) prior to transmission to the UE. The UE then detects the modified MAC headers to identify the start and/or end of silence periods.

A method for instructing a mobile node to reduce the power used to transmit channel quality information is described. A scheduling mode of a mobile node is determined. An uplink control channel in a first format is allocated to the mobile node if the mobile node is in a first scheduling mode. The number of bits to use to insert channel quality information (CQI) on the uplink control channel is provided. The mobile node is instructed to reduce the power used to transmit CQI by a power reduction amount if the mobile node is in the first scheduling mode.

The uplink control channel in the first format carries either the CQI or acknowledgment/non-acknowledgment (ACK/NAK) information. The CQI or the ACK/NAK information is inserted into the uplink control channel. Either the CQI or the ACK/NAK information is transmitted through uplink control channel.
