A pipelined decoder for storaging of soft bits and hard bits associated with code blocks of a transmission. The proposed circuit reduces the amount of memory needed at the receiver level for soft bits and hard bits, in a pipelined decoder. Namely, with the solution of the subject application, both the LLRs and hard bits associated with a given code block are available when the CRC value is determined. Hence, the effect obtained non-pipelined decoder is achieved by the pipelined decoder of the subject application. A receiver for a wireless communication system, a method and a computer program are also disclosed.

A method for a User Equipment (UE) operating in a wireless communication system, the method includes receiving an Radio Resource Control (RRC) message for reconfiguring a new value of a Packet Data Convergence Protocol (PDCP) reordering timer, while the PDCP reordering timer is running; and setting a value of reordering_PDCP_RX_COUNT to a COUNT value associated to RX_HFN and Next_PDCP_RX_SN when the RRC message is received.

In the present invention, the transmitting device attaches a sequence number (SN) for each of service data unit (SDU) elements to generate a protocol data unit (PDU) containing the SDU elements. Each of the SDU elements is a SDU or SDU segment. The PDU includes the SDU elements and respective SNs for the SDU elements. The PDU includes an indicator for each of the SDU elements, and the indicator indicating whether a corresponding SDU element is a SDU or SDU segment.

Input/output (I/O) operation requests from pageable storage mode guests are interpreted without host intervention. In a pageable mode virtual environment, requests issued by pageable storage mode guests are processed by one or more processors of the environment absent intervention from one or more hosts of the environment. Processing of the requests includes manipulating, by at least one processor on behalf of the guests, buffer state information stored in host storage. The manipulating is performed via instructions initiated by the guests and processed by one or more of the processors.

Methods and apparatus are provided for quick recovery of missed packets after a user equipment (UE) tunes back to a first network after tuning away from the first network. The UE may determine that a trigger event has occurred, and in response to the determination, modify a negative acknowledgement (NACK) timing configuration from a default configuration. Modifying the NACK timing configuration may include using an aggressive NACK timing configuration for a configurable period of time, in response to detecting a trigger event. The trigger event may include detecting missed packets after a tune back, unavailability of sufficient memory to hold packets until a gap created by missed packets may be filled, or tuning back to a network.

A system may include primary and secondary integrated circuits. The primary integrated circuit may receive a first subset of data packets associated with a first set of sequence numbers. The secondary integrated circuit may receive a second subset of data packets associated with a second set of sequence numbers. The primary integrated circuit is configured to manage the first set of sequence numbers and the second set of sequence numbers on behalf of the secondary integrated circuit and for the system.

Methods and apparatuses are provided for generating a protocol data unit (PDU). A method may include transmitting a medium access control (MAC) protocol data unit (PDU) include information associated with one or more logical channels. The MAC PDU to be transmitted may be assembled by determining an amount of information associated with one of the one or more logical channels to be included in the MAC PDU; and multiplexing one or more complete service data units (SDUs) associated with at least the one of the one or more logical channels into the MAC PDU. On a condition that multiplexing an additional SDU associated with the one of the one or more logical channels would exceed the determined amount of information, the one or more complete SDUs may be multiplexed with a segment of the additional SDU associated with the one of the one or more logical channels and a header indicating that the segment is not a last segment of the additional SDU.

In the present invention, the transmitting device attaches a sequence number (SN) for each of service data unit (SDU) elements to generate a protocol data unit (PDU) containing the SDU elements. Each of the SDU elements is a SDU or SDU segment. The PDU includes the SDU elements and respective SNs for the SDU elements. The PDU includes an indicator for each of the SDU elements, and the indicator indicating whether a corresponding SDU element is a SDU or SDU segment.

Aspects of the disclosure provide techniques for automatic repeat request (ARQ) in a free-space optical communication (FSOC) architecture. These techniques, including block-selective ARQ, adaptive retransmission delay, and random seed scrambling, can be used individually or in combination to combat problems involving frame loss or corruption. These techniques enable the system to rapidly recover by streamlining the retransmission process. For instance, block-selective ARQ acknowledges variable length blocks of frames in the return stream from the receiver to the transmitter. Adaptive retransmission delay allows the retransmission delay to grow in the absence of feedback by the receiver, up to some defined limit. And with random seed sampling, a scrambling sequence is incorporated to aid with frame syncing, which avoids the need for a line code. These aspects of the technology provide a robust communication process, and also reduce overhead costs associated with unnecessary retransmissions.

System and method indicating delays added to packets due to retransmission events. The method includes the steps of receiving multiple packet streams and multiplexing them into a first multiplexed packet stream; storing in memory the first multiplexed packet stream together with time indications; receiving a retransmission request and selecting data for retransmission; multiplexing the first multiplexed packet stream and the data for retransmission into a second multiplexed packet stream; utilizing the time indications for calculating delays that were added to packets of the second multiplexed packet stream as a result of fulfilling the retransmission request; adding the calculated delays to at least some of the packets of the second multiplexed packet stream; and transmitting the second multiplexed packet stream.
