摘要： The present invention provides a fast and efficient retransmission technique, which allows a link control layer to request retransmission of frames upon receiving information from an underlying physical layer that an unsuccessful attempt to transmit data was detected. In general, a failed attempt to transmit a frame is detected at a physical layer of a receiver. In response, the physical layer of the receiver sends a message to a link control layer of the receiver to indicate the failed attempt to transmit a frame was detected. Upon receipt of the message, the link control layer sends a retransmission message to a corresponding link control layer of a sender. The retransmission message is configured to cause the sender to retransmit the unrecoverable data associated with the corrupted frame.

摘要： A radio link protocol for a communications system ensures that delivery of Internet protocol data packets occurs within a set delay bound for the packets, in order to satisfy specified quality of service levels. Data packets arriving at a transmitter are subdivided into data blocks. As each block is transmitted, the transmitter starts an associated acknowledgement timer. The timer is turned off, before it expires, if the transmitter timely receives from a receiver a message informing the transmitter that the associated block was successfully received. If such message is not received, the timer expires and the transmitter sends an acknowledgement request signal to the receiver and starts an associated panic timer. The panic timer is turned off, before it expires, if the transmitter subsequently timely receives a message that the associated block was successfully received. If such message not received, the panic timer expires and the transmitter sends one of more copies of the corresponding block to the receiver before occurrence of the delay bound. If the transmitter receives a negative acknowledgement message from the receiver, that a block is missing or corrupted, the transmitter retransmits a copy of the block to the receiver. To reduce messaging traffic, the transmitter cancels acknowledgement and panic timers based upon information contained in negative acknowledgement messages, and the receiver can periodically send acknowledgement messages to inform the transmitter of successfully received blocks.

摘要： The present invention keeps track of channel change indicia associated with wireless communications with mobile terminals, and bases the scheduling of data in time slots of a scheduling period on the channel change indicia. The channel change indicia may be derived from any information that bears on the rate at which channel conditions are likely to change, such as the velocity the mobile terminals are traveling or actual channel condition measurements. Preferably, mobile terminals associated with intermediate values for the channel change indicia are given priority, and thus, scheduled for transmission before those with lower and higher values. The invention is applicable to uplink and downlink communications, and is particularly beneficial when implemented in uplink and downlink schedulers in a base station.

摘要： A method for communicating channel state information (CSI) to a base station is presented. The method includes identifying a number of allocated resources for CSI within at least one of a Physical Uplink Control CHannel (PUCCH) payload and a Physical Uplink Shared CHannel (PUSCH) payload. The method includes encoding channel state information (CSI) for activated carriers on a user equipment into the allocated resources for CSI. When a number of activated carriers on the user equipment is less than the number of allocated resources for CSI, the method includes using repetition encoding to duplicate the CSI for at least one of the activated carriers on the user equipment into the allocated resources for CSI.
