System and method for information delivery with multiple point transmission
A system and method for information delivery with multiple point transmission are provided. A method for detecting lost packets is provided. The method includes initiating a timer for a received packet at a receiving transmission point, where the timer is set according to a time value associated with the received packet. The method also includes determining that a delivery of the received packet has failed according to the timer elapsing, and transmitting a lost packet report to a primary transmission point that distributed the received packet to the receiving transmission point.
TECHNIQUES FOR PACKET DATA CONVERGENCE PROTOCOL REORDERING WITHIN A TIMER
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver device may receive a first packet of a plurality of packets included in a reordering window of the receiver device. The receiver device may receive a second packet of the plurality of packets. The receiver device may provide the first packet and the second packet based at least in part on expiration of a reordering timer. The receiver device may receive a third packet of the plurality of packets at a third time, wherein the first packet, the second packet, and the third packet are received sequentially. The receiver device may provide a set of packets including the first packet, the third packet, and the second packet in order, to a higher layer in accordance with a timer that is shorter than a length of the reordering window. Numerous other aspects are described.
TECHNIQUES FOR PACKET DATA CONVERGENCE PROTOCOL ORDERING AFTER EXPIRATION OF A TIMER
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver device may receive a first packet of a plurality of packets included in a reordering window of the receiver device. The receiver device may receive a second packet of the plurality of packets. The receiver device may provide the first packet and the second packet based at least in part on expiration of a reordering timer. The receiver device may receive a third packet of the plurality of packets at a third time, wherein the first packet, the second packet, and the third packet are received sequentially. The receiver device may provide a set of packets including the first packet, the third packet, and the second packet in order, to a higher layer in accordance with a timer that is shorter than a length of the reordering window. Numerous other aspects are described.
Receiving method, sending method, and communications device
A receiving method, a sending method and communications device are provided. The receiving method includes: obtaining a duplication detection parameter; and performing duplication detection on a received sidelink packet data convergence protocol PDCP protocol data unit PDU by using the duplication detection parameter.
Technique for storing softbits
A technique for storing softbits of messages received according to a Hybrid Automatic Repeat Request (HARQ) protocol is disclosed. As to a method aspect of the technique, a first storage (102) and a second storage (104) are provided. The first storage and a second storage include a plurality of memory segments (103) allocatable to HARQ processes. A first message related to a first HARQ process is received. The first message is protected by a channel code of the HARQ protocol and represented by softbits. The softbits of the first message are stored in a first segment of the first storage. The first segment is allocated to the first HARQ process. The first storage is accessible by a channel decoding unit (110) for decoding the channel code. If a number of allocated segments in the first storage, the decoding of which has not been yet completed, exceeds a threshold, the allocation for the first HARQ process is changed from the first segment in the first storage to a second segment in the second storage.
Set buffer state instruction
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.
METHOD AND DEVICE FOR TRANSMITTING DATA UNIT
A radio link control (RLC) entity of a transmitting device receives a first RLC service data unit (SDU) from an upper layer of the transmitting device. If the RLC entity receives, from the upper layer, a discard indication to discard the first RLC SDU, the RLC entity checks whether the first RLC SDU has been submitted to a lower layer of the transmitting device. The RLC entity discards the first RLC SDU if neither the first RLC SDU nor a segment of the first RLC SDU has been submitted to the lower layer.
SYSTEM, METHOD AND APPARATUS FOR QoS RETRANSMISSION FOR MG.Fast
A transceiver associated with a wireline communication system is disclosed. The transceiver comprises one or more processors configured to associate a quality of service (QoS) grade tag to each data packet of a plurality of data packets to be transmitted and assemble a data transfer unit (DTU) comprising one or more or a part of a data packet of the plurality of data packets, wherein the one or more or the part of the data packet are encapsulated into a plurality of DTU frames within the DTU. The one or more processors is further configured to associate a highest DTU tag to the assembled DTU, wherein the highest DTU tag is indicative of a highest QoS grade associated with the DTU frames of the assembled DTU; and determine a schedule for transmission or retransmission of the assembled DTU, based on the highest DTU tag of the assembled DTU.
METHOD AND APPARATUS FOR DATA PROCESSING IN WIRELESS COMMUNICATION SYSTEM
The present disclosure relates to a communication scheme and system for the convergence of a 5G communication system for supporting a higher data transfer rate than a post-4G system and the IoT technology. The present disclosure may be applied to intelligent services (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and safety services) based on the 5G communication technology and IoT-related technology. One embodiment of the present disclosure relates to a method and apparatus for processing data in a wireless communication system.
Device and Method for Handling a Packet Data Convergence Protocol Operation
A first communication device for handling a PDCP operation comprises at least one storage device for storing instructions and at least one processing circuit coupled to the at least one storage device. The at least one processing circuit is configured to execute the instructions stored in the at least one storage device. The instructions comprise receiving a first plurality of PDCP Data PDUs associated to a radio bearer (RB), from a second communication device; processing the first plurality of PDCP Data PDUs according to a RX_NEXT, a RX_DELIV and a RX_REORD; updating the RX_NEXT, the RX_DELIV and the RX_REORD; performing a PDCP reestablishment; setting the RX_NEXT, the RX_DELIV and the RX_REORD to a plurality of initial values; receiving a second PDCP Data PDU associated to the RB, from the second communication device; and processing the second PDCP Data PDU according to the RX_NEXT, the RX_DELIV and the RX_REORD.
