File-based downlink transmission and retransmission
Disclosed are techniques for wireless communication. In an aspect, a network entity transmits, to a user equipment (UE), at least one file, the at least one file comprising a group of data packets, wherein each data packet of the group of data packets of the at least one file is associated with a file identifier of the at least one file, transmits, to the UE, after transmitting the last data packet of the group of data packets of the at least one file, a request for the UE to report a reception status of the at least one file, transmits, to the UE, one or more repair bits for the at least one file, receives an acknowledgment from the UE, and ceases transmission of the one or more repair bits upon reception of the acknowledgment from the UE.
Superposition of sidelink and uplink transmissions
Methods, systems, and devices for wireless communications are described. A first user equipment (UE) in a wireless communications system, such as a vehicle-to-everything (V2X) communications systems, may communicate over sidelink to other UEs. The first UE may receive, from a base station, control signaling indicating a sidelink resource pool allocated for sidelink communication between the first UE and a second UE. The first UE may transmit an indication that superposition coding may be used to generate a concurrent sidelink and uplink transmission. The first UE may then transmit the concurrent sidelink and uplink transmission within a resource of the sidelink resource pool based on the indication. The second UE may decode the sidelink portion of the transmission, and the base station may decode the uplink portion of the transmission.
Method and apparatus for grant-free data transmission in wireless communication system
A method performed by a terminal in a communication system is provided. The method includes identifying a first physical downlink shared channel (PDSCH) scheduled by a physical downlink control channel (PDCCH), and a second PDSCH without a corresponding PDCCH; identifying that the first PDSCH and the second PDSCH are overlapped in time; and decoding the first PDSCH on a basis that the PDCCH scheduling the first PDSCH ends at least 14 symbols before the starting symbol of the second PDSCH.
Enhancement for bandwidth part (BWP) operation towards secondary cell (SCELL) dormancy indication
A method for enhancing Bandwidth Part (BWP) operation towards Secondary Cell (SCell) dormancy indication is proposed. A User Equipment (UE) detects a Downlink Control Information (DCI) format including an SCell dormancy indication that indicates an active BWP change for a serving cell. The UE performs BWP switching for the serving cell in response to the DCI format. The UE stops transmission or reception in the serving cell during a time duration from a slot containing a last symbol of the DCI format, wherein the time duration includes a first period of time of delay for the BWP switching and a second period of time of interruption to other active serving cells.
HANDLING HYBRID AUTOMATIC REPEAT REQUEST PROCESS IN CONFIGURATION GRANT ACTIVATION AND DEACTIVATION PROCEDURE
A wireless device operating in a communication network can, responsive to receiving a downlink control indication (“DCI”) command to activate or reactivate a configured grant (“CG”) configuration, control at least one timer associated with a non-idle hybrid automatic repeat request (“HARQ”) process on the CG configuration. The non-idle HARQ process can include a process of retransmitting a transmission block (“TB”) using the CG for which an associated media access control (“MAC”) protocol data unit (“PDU”) has been submitted to lower layers for transmission to a network node, but for which successful reception acknowledgment has not been received from the network node.
INFORMATION GENERATION METHOD, DEVICE, AND STORAGE MEDIUM
Provided are an information generation method, a device, and a storage medium. The method includes: receiving a DCI sent by a second communication node, where the DCI is used for scheduling at least one PDSCH; and generating a corresponding feedback codebook according to a C-DAI value and a T-DAI value which are contained in a DAI indicator field in the DCI.
User Equipment-Coordination Set Hybrid Automatic Repeat Request
Techniques and apparatuses are described for user equipment-coordination set, UECS, hybrid automatic repeat request, HARQ, that establish a HARQ timeline that is specific to the capabilities of a respective UECS. Compared to a single user equipment, UE, the HARQ timeline for a UECS depends on a number of factors, such as the joint processing capability in the UECS, latency of communication over a local wireless network between the UEs in the UECS, or the like. Based on its capabilities, the UECS can request uplink and/or downlink processing delay times or a UECS-specific HARQ timeline from a base station. The base station grants the uplink and/or downlink processing delay times or the UECS-specific HARQ timeline to the UECS in a layer-1, layer-2, or a layer-3 control message. The use of a UECS-specific HARQ timeline increases the reliability of HARQ signaling for uplink and downlink communication between the UECS and a base station.
METHODS AND DEVICES FOR CONFIGURING HARQ-ACK FEEDBACK
The present disclosure describes methods, system, and devices for configuring hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback for physical downlink shared channel (PDSCH) transmission. The method includes receiving, by a user equipment (UE), a radio resource control (RRC) parameter to configure a one-shot HARQ-ACK feedback mode; and receiving, by the UE, a first downlink control information (DCI) comprising a first K, the first DCI corresponding to a first PDSCH. The method includes receiving, by the UE, a second DCI comprising a second K with an applicable value and an one-shot request field with a positive value, the second DCI corresponding to a second PDSCH; and transmitting, by the UE, a one-shot HARQ-ACK feedback according to a preset rule.
MESSAGE EXCHANGE BETWEEN COMPUTING DEVICES OPERABLE TO IMPLEMENT COAP
An instructing computing device (210) is disclosed that is operable to implement a 5Constrained Application Protocol (CoAP). The computing device comprises processing circuitry configured to send a first message (211) to a target computing device (220), which comprises a first message identifier and store a record (212) of the first message in a memory. The processing circuitry is further configured to receive a second message (223) from the target computing device, the second message confirming that 0the target computing device has received the first message, wherein the first message is configured to cause the target computing device to store a record (222) of the first message.
Frequency Hopping in Multiple Transmission and Reception Points
A wireless device receives one or more configuration parameters indicating a mapping pattern that indicates a cyclical mapping of spatial domain transmission filters to physical uplink shared channel (PUSCH) repetitions. The wireless device receives a downlink control information (DCI) scheduling repetitions of a PUSCH transmission, where the DCI comprises a frequency hopping field set to one and indicates a frequency offset. Based on the frequency hopping field being set to one and the mapping pattern indicating the cyclical mapping, the wireless device sequentially transmits, starting from a first resource block, a first repetition of the PUSCH transmission using a first spatial domain transmission filter and a second repetition using a second spatial domain transmission filter; and sequentially transmits, starting from a second resource block, a third repetition using the first spatial domain transmission filter and a fourth repetition using the second spatial domain transmission filter.
