Abstract: In one embodiment, a method in a wireless device for adaptive HARQ retransmissions comprises receiving, from a network node, a request to initiate an adaptive hybrid automatic repeat request (HARQ) retransmission. The method comprises identifying a HARQ process associated with the HARQ retransmission request and determining whether a HARQ buffer of the HARQ process is empty. In response to determining that the HARQ buffer is empty, the method comprises not delivering the HARQ information to the HARQ process and not triggering an adaptive HARQ retransmission.

Abstract: Methods and apparatuses are provided for performing communication in a wireless communication system is provided. A number of hybrid automatic repeat request (HARQ) processes is set as N. The N is a natural number, one value within a maximum value, 16, and set based on a configuration of a base station (BS). Downlink control information (DCI) is received including a 1-bit HARQ-acknowledgment (HARQ-ACK) feedback request for all of N HARQ processes. HARQ-ACK information associated with all of the N HARQ processes is identified, based on the received DCI. A number of bits for the HARQ-ACK information is defined based on xN by the configuration, and the x is a natural number. The HARQ-ACK information is transmitted to the BS.

Abstract: A radio device (100) sends a radio transmission (503, 507) to a further radio device (150). Further, the radio device (100) receives a further radio transmission (505, 509) from the further radio device (150). The further radio transmission (505, 509) comprises an indicator of reception success. In response to the indicator being toggled with respect to a previous state of the indicator, the radio device (100) determines that the radio transmission (509) was successfully received by the further radio device (150). In response to the indicator not being toggled with respect to the previous state of the indicator, the radio device (100) determines that the radio transmission (503) failed.

Abstract: Techniques provided herein select an operating mode from a plurality of operating modes. Various implementations establish a radio bearer with at least one network entity over a network using a first Radio Link Control (RLC) protocol entity and a second RLC protocol entity. Various implementations determine whether packet duplication is enabled for the radio bearer by processing Packet Data Convergence Protocol (PDCP) configuration settings. In response to determining that packet duplication is enabled, various implementations duplicate uplink data packets over the network by submitting the uplink data packets to both the first RLC protocol entity and the second RLC entity. In response to determining that packet duplication is disabled and split bearer is enabled, various implementations select one of the first RLC protocol entity and the second RLC protocol entity for uplink data packet transmission.
