NON-DROPPING RULE FOR MINI-SLOT BASED REPETITION
Aspects relate to implementing a non-dropping rule for mini-slot based repetition of downlink channel data or control. In one example, cancelled repetition may be identified, non-cancelled remaining repetitions may be received, and acknowledgment feedback based on reception results may be generated. In another example, a plurality of time domain resource allocation (TDRA) candidate occasions may be identified where each occasion occurs within a different respective one of a plurality of mini-slots, each mini-slot carrying a different respective one of a plurality of downlink channel repetitions. A TDRA table may be maintained. The TDRA table may include TDRA entries such as location information of the plurality of TDRA candidate occasions associated with the plurality of downlink channel repetitions. The TDRA table may be maintained when at least one of the plurality of downlink channel repetitions is not decoded. A wireless communication device may refrain from dropping non-decoded downlink channel repetitions.
UPLINK TRANSMISSION AND RECEPTION METHOD AND DEVICE IN WIRELESS COMMUNICATION SYSTEM
An uplink transmission and reception method and device in wireless communication system are disclosed. A method by which a terminal performs uplink transmission in a wireless communication system, according to one embodiment of the present disclosure, may comprise the steps of: receiving configuration information related to a plurality of sounding reference signal (SRS) resource sets; receiving downlink control information (DCI), which indicates at least one from among a first SRS resource set, a second SRS resource set, or the first SRS resource set and the second SRS resource set and includes information indicating at least one SRS resource in the indicated at least one SRS resource set; and performing the uplink transmission on the basis of the indicated at least one SRS resource.
Systems and methods for failure recovery in at-most-once and exactly-once streaming data processing
This patent document describes failure recovery technologies for the processing of streaming data, also referred to as pipelined data. The technologies described herein have particular applicability in distributed computing systems that are required to process streams of data and provide at-most-once and/or exactly-once service levels. In a preferred embodiment, a system comprises many nodes configured in a network topology, such as a hierarchical tree structure. Data is generated at leaf nodes. Intermediate nodes process the streaming data in a pipelined fashion, sending towards the root aggregated or otherwise combined data from the source data streams towards. To reduce overhead and provide locally handled failure recovery, system nodes transfer data using a protocol that controls which node owns the data for purposes of failure recovery as it moves through the network.
SIDELINK ROBUSTNESS ENHANCEMENT FOR MULTI-TRP UE
Certain aspects of the present disclosure provide techniques for enhancing sidelink communications between devices. As described herein, a single sidelink control information (SCI) may schedule sidelink data transmissions with repetition in time and/or frequency.
Repetition-based transmissions
Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a transmitting device may be configured to transmit a transport block in a set of transmission time intervals (TTIs) of a repetition window to improve the chances that the transport block is received by a receiving device. In some cases, however, the transport block may not be available to be transmitted in the repetition window until after a first TTI of the repetition window. In such cases, a transmitting device may use the techniques described herein to identify appropriate configurations for transmitting the transport block in the repetition window. For example, the transmitting device may identify an adjusted redundancy version sequence to use for transmitting the transport block in the repetition window or the transmitting device may adjust a repetition window based on a TTI in which the transport block is available to be transmitted.
Method for use in transmitting URLLC data in NR system
In the present invention, a common UL control channel resources is configured and scheduled for sharing among URLLC UEs (102) within a servicing cell. An enhanced HARQ-less transmission technique (20) is employed for delivering DL URLLC data packets to the intended UEs (102). On DL URLLC data transmission basis, via a scheduling DCI, a gNB (101) dynamically indicates to the intended URLLC UE (102), the UL control resource including the time slots for use in transmitting limited acknowledge information.
Resource exclusion in a half duplex based wireless communication system
Methods, apparatuses, and computer-readable mediums for wireless communication by a user equipment (UE) includes transmitting a packet on a first resource, determining one or more repetition resources on which to send one or more redundancy versions of the packet, wherein the one or more repetition resources are at a time subsequent to the first resource, transmitting repetition resource information identifying the one or more repetition resources to one or more neighboring UEs, and transmitting the one or more redundancy versions of the packet on respective ones of the one or more repetition resources.
Techniques for determining a number of (re)transmissions in wireless communications
Aspects described herein relate to determining a congestion level related to communicating with one or more devices in a wireless network, determining, based on the congestion level, a retransmission scheme for transmitting and/or retransmitting communications in the wireless network, and transmitting or retransmitting a communication in the wireless network based on the retransmission scheme.
Method and apparatus for handling repetitions of physical uplink shared channel (PUSCH) transmission in a wireless communication system
A method performed by a BS for handling repetitions of transmissions is provided. The method includes transmitting an RRC configuration including a first parameter configured with a first value and a second parameter configured with at least one second value; and transmitting DCI on a PDCCH scheduling a PUSCH transmission. The DCI enables the UE to select one of the first parameter and the second parameter to determine a number of PUSCH repetitions; determine the number of PUSCH repetitions as the first value when the first parameter is selected; determine the number of PUSCH repetitions as one of the at least one second value indicated by the DCI when the second parameter is selected; and perform the PUSCH transmission for a number of times based on the number of PUSCH repetitions. A BS using the aforementioned method is also provided.
Selective retransmission for vehicle-to-everything communications
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a warning message comprising a first indication of a priority of the warning message and a second indication that identifies an event. The UE may transmit a repetition of the warning message based at least in part on the first indication. Numerous other aspects are described.
