Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. According to embodiments of the present disclosure, a terminal device receives, from a network device, a radio resource control (RRC) configuration comprising a repetition number for physical uplink shared channel (PUSCH) transmission occasions associated with a first sounding reference signal (SRS) resource indicator (SRI) and PUSCH transmission occasions associated with a second SRI, the RRC configuration further comprising a redundancy version (RV) offset to a RV sequence associated with the first SRI. The terminal device receives DCI indicating an identity of a RV. If a first RV sequence determined based on the repetition number, the identity and the RV offset meets a condition, the terminal device does not apply the first RV sequence. In this way, it improves reliability.

Abstract: The present technology relates to a reception terminal and a method capable of achieving stable voice transmission regardless of the device.
A reception terminal receives a packet transmitted from a transmission terminal, the packet including main data and redundant data generated on the basis of a redundancy degree determined on the basis of a retransmission timeout period that is a time determined by a combination of the transmission and reception terminals and in which retransmission processing of the main data can be repeatedly executed and used for restoration or interpolation of the main data, and decodes reproduction data by decoding the main data or the redundant data. The present technology can be applied to a communication system that performs voice transmission using BLE.

Abstract: This application provides a communication method and a communications device. The method includes: A first device receives a first message sent by a second device. The first message is used to indicate a bearer configuration of a bearer of the first device and an initial status of the bearer configuration, and the bearer configuration includes a first bearer configuration and/or a second bearer configuration. The first device determines the bearer configuration and the initial status of the bearer configuration based on the first message. According to the technical solutions in embodiments of this application, a bearer configuration of a terminal device and an initial status of the bearer configuration of the terminal can be indicated. Because both the bearer configuration of a bearer of the terminal and the initial status of the bearer configuration of the terminal are indicated, communication efficiency is improved.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may be configured to transmit a transport block multiple times 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, the UE may use the techniques described herein to identify appropriate configurations for transmitting the transport block in the repetition window. In particular, the UE may determine whether to use a fixed repetition window or a sliding repetition window for transmitting the transport block based on various factors in an attempt to satisfy latency and reliability constraints associated with the transport block.

Abstract: Apparatus, methods, and computer-readable media for facilitating a multiple bit new data indicator are disclosed herein. An example method for wireless communication at a first device includes transmitting a first state of a multiple bit new data indicator (NDI) for a first packet. The example multiple bit NDI indicates more than two different states for indicating a new packet. The example method also includes transmitting the first packet. Additionally, the example method includes transmitting a second state of the multiple bit NDI for a second packet, and the second state being different than the first state. Further, the example method includes transmitting the second packet.

Abstract: Methods, systems, and devices for wireless communications are described. One method may include a user equipment (UE) receiving, in a first transmission time interval, a code block group including a set of code blocks associated with a set of codewords, each codeword being associated with one of a set of decoding levels introduced in communication scheme that uses multi-level coded modulation and multi-level sequential decoding. The UE may determine that a decoding procedure is unsuccessful, and transmit a feedback message including a first indicator that the decoding procedure was unsuccessful and a second indicator of a lowest decoding level for which the decoding procedure was unsuccessful. The UE may then receive, from the base station in a second transmission time interval, a retransmission of code blocks of the lowest failed decoding level coupled to a new data transmission for code blocks associated with all other decoding levels.
