Abstract: A method, apparatus, and computer program product are disclosed for reporting time and frequency compensation updates to a base station in a 5G network. In this regard, an example method is configured to determine an actual time domain window based at least in part on a time domain window received at the user equipment from a base station, and on at least one adjustment to at least one of time or frequency of a reference signal due to a physical characteristic of a transmission environment. The example method may further cause a compensation report to be transmitted to the base station in a control channel message within the uplink communication stream. The compensation report includes an indication of the at least one adjustment. The method further causes the reference signal to be transmitted in the actual time domain window to the base station.

Abstract: To enable at least dynamic waveform switching, at least one predefined bit, in a downlink control information comprising scheduling information for at least one uplink transmission, may have a first preset purpose and a second preset purpose. One or more preset first rules may be applied to determine whether to use the at least one predefined bit for the first preset purpose or for the second preset purpose. When the second preset purpose is used, at least a waveform for the at least one uplink transmission amongst waveforms comprising at least a first waveform and a second waveform is determined, according to one or more preset second rules, based on a value of the at least one predefined bit. The waveform determined is then used in the uplink transmission scheduled.

Abstract: According to an example implementation, a method for frequency offset reporting includes transmitting, by a first transceiver, a first tracking reference signal to a user device in a wireless communication system, transmitting, by a second transceiver, a second tracking reference signal to the user device, receiving, by the base station, a channel state information (CSI) reporting signal via an uplink channel, where the CSI reporting signal includes power estimation information. The method includes determining whether to pre-compensate a frequency of a downlink signal with frequency offset information based on the power estimation information, and transmitting, by at least one of the first transceiver or the second transceiver, the downlink signal with the pre-compensated frequency in response to the determination to pre-compensate the frequency of the downlink signal.

Abstract: A method may include receiving, by a user device from a network node in a wireless network, an indication that a plurality of frequency hop resource entities should be shifted, wherein each frequency hop resource entity is configured with a frequency allocation according to a sequence or order of frequency allocations; performing, by the user device, a shifting of the frequency hop resource entities, wherein each frequency hop resource entity includes one or more demodulation reference signal (DMRS) symbols and one or more data symbols, wherein the shifting causes each of the frequency hop resource entities to be shifted by one frequency hop resource position and to be allocated a different frequency allocation; and transmitting, by the user device to the network node, the plurality of shifted frequency hop resource entities.

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.
