Abstract: To enable dynamic waveform switching, one or more instructions on how to determine a waveform amongst at least a first waveform and a second waveform for at least one uplink transmission based at least on frequency domain resource allocation for the at least one uplink transmission may be transmitted in a network, or apparatuses may comprise one or more of the one or more instructions. The one or more instructions associate at least resource block regions with waveforms. The one or more instructions may be applied to determine, based on a frequency domain resource allocation for an uplink transmission, a waveform for the uplink transmission at least according to a resource block region in the frequency domain resource allocation. The waveform determined is then used in the uplink transmission.

Abstract: Embodiments of the present disclosure relate to methods, devices, apparatuses and computer readable storage media for Uplink Control Information (UCI) design. The method comprises determining, at a terminal device, a matrix comprising a set of non-zero linear combination coefficients for quantizing a channel between the terminal device and a network device, the matrix having spatial components and frequency components; shifting the frequency components of the matrix circularly, such that a target coefficient of the set of non-zero linear combination coefficients is located in a frequency component with a predetermined index of the frequency components in a shifted matrix; generating a first indication indicating the spatial component associated with the target coefficient in the matrix; and transmitting, to the network device, uplink control information comprising the first indication. In this way, a new solution for designing the UCI may reduce the overhead for reporting the parameters in the UCI.

Abstract: Example embodiments of the present disclosure relate to apparatuses, methods, and computer readable storage medium for bandwidth part switching. In a method, a first apparatus receives a downlink control information (DCI) message in a first bandwidth part (BWP). Based on at least one condition related to at least enabling of a dynamic transform precoder indication (DTPI) information element configured for the second BWP, the first apparatus determines at least one of a resource allocation type or a state of transform precoder for the PUSCH transmission. The first apparatus performs a transmission to a second apparatus on the second BWP using the at least one of the resource allocation type or the state of transform precoder for the PUSCH transmission.

Abstract: Example embodiments of the present disclosure relate to methods, devices, apparatuses and computer readable storage medium for Random Access Channel (RACH) occasion (RO) dropping. In a method, a device determines a set of valid random access channel occasions (ROs) for a physical random access channel (PRACH) transmission with preamble repetitions. The device determines that the PRACH transmission is to be dropped in at least one RO of the set of valid ROs. The device determines one or more ROs of the set of valid ROs for calculation of a random access radio network temporary identifier (RA-RNTI), the one or more ROs for calculation of the RA-RNTI are not conditioned to whether the corresponding PRACH transmission over the one or more ROs is to be dropped. Then the device calculates the RA-RNTI based on the determined one or more ROs of the set of valid ROs.

Abstract: A method, apparatus, and computer program product are provided. In the context of a method, the method includes identifying a scheduled transmission interval having a beginning time and an end time, based on initial scheduling information received from a network node, where the scheduled transmission interval is longer than a threshold duration for an uplink transmission by the user equipment according to initial scheduling information, where the scheduled transmission interval includes a head end portion and a tail end portion, and the tail end portion accommodates a monitoring period. The method includes transmitting respectively, to a network node, an uplink transmission corresponding to a respective subsequent scheduled transmission interval, according to subsequent scheduling information received from the network node, within the monitoring period before the end time.
