  • Publication number: 20220330161
    Abstract: Aspects relate to wireless communication having sounding reference signal (SRS) power control using non-scheduling downlink control information (DCI) that is configured to trigger aperiodic SRS without scheduling data and without a channel state information (CSI) request. The non-scheduling is configured to include at least two transmit power control (TPC) commands A first TPC command is configured for power control of a physical uplink shared channel (PUSCH) transmitted by a UE to a base station. A second TPC command is configured for power control of one or more sounding reference signal (SRS) resource sets. Additionally, the first TPC command may be independent from the second TPC command where different power control is implemented for the PUSCH and the SRS transmissions. Additionally, the non-scheduling DCI may be formatted according to a DCI format 0_1 or a DCI format 0_2.

  • Publication number: 20220322332
    Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may receive, from a base station, a control message including an indication of a reference signal configuration associated with one or more physical channels scheduled during a set of time intervals. The UE may identify that demodulation reference signal is absent in a first time interval. In some examples, the UE may determine, based on the control message, a location for transmitting a phase tracking reference signal in the first time interval of the set of time intervals. The UE may then transmit the phase tracking reference signal in the first time interval at the determined location.

  • Publication number: 20220321167
    Abstract: Aspects presented herein may enable a UE to determine whether phase continuity is to be maintained for one or more uplink transmissions when the UE is configured with a frequency-hopping with zero frequency offset. In one aspect, a UE receives, from a network entity, an indication of frequency hopping with zero frequency offset. The UE determines whether phase continuity is to be applied to UL transmissions based on the indication of the frequency hopping with zero frequency offset. The UE transmits, to the network entity, at least one uplink channel with no phase continuity based on the determination to not apply phase continuity to the UL transmissions.

  • Publication number: 20220322188
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a source base station associated with a source master cell group (MCG), a physical uplink shared channel (PUSCH) repetition in one or more slots of the source MCG during a handover of the UE from the source MCG to a target MCG. The UE may perform, to a target base station associated with the target MCG, an uplink transmission in one or more slots to the target MCG during the handover, wherein PUSCH repetitions associated with the source MCG that overlap in time with the uplink transmission to MCG are canceled and a counting of the PUSCH repetitions is based at least in part on slots of the source MCG associated with canceled PUSCH repetitions. Numerous other aspects are described.

  • Publication number: 20220321389
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling indicating a first set of thresholds corresponding to a first set of reference signal densities and a second set of thresholds corresponding to a second set of reference signal densities. The first set of thresholds may be associated with enabled uplink demodulation reference signal (DMRS) bundling, and the second set of thresholds may be associated with disabled uplink DMRS bundling. The UE may select a reference signal density from the first set or the second set based on a DMRS bundling status and map reference signaling (e.g., a DMRS, a phase tracking reference signal (PTRS), or both) to a set of resources based on the reference signal density. Uplink channel repetitions may occur in disjoint symbols and in such cases, DMRS bundling may be activated when PTRSs between repetitions meet a threshold.

  • Publication number: 20220312442
    Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may be configured with periodic uplink grants that provide a number of repetitions and a redundancy version (RV) sequence for the repetitions. Prior to the start of an uplink grant period, the UE may determine a set of slots that are available for uplink transmissions in the uplink grant period. Based on the set of slots, the UE may determine a corresponding RV for repetitions of the uplink communication associated with each slot. The slots with uplink transmissions within the uplink grant period may be non-contiguous. Repetitions of an uplink communication may be configured to be transmitted across multiple uplink grant periods, which may be triggered based on a threshold value associated with the repetitions.

  • Patent number: 11451425
    Abstract: Techniques for peak-to-average power ratio (PAPR) reduction are described. Wireless devices may use one or more PAPR shaping resources, such as expanded bandwidth and/or pulse-shaping filtering, for shaping a signal to reduce PAPR. For example, expanded bandwidth may be utilized for adding a cyclic affix (CA), such as may comprise a cyclic prefix (CP), cyclic suffix (CS), etc., and combinations thereof, to a frequency domain data signal to provide a CP augmented frequency domain data signal used to generate a reduced PAPR time domain data signal. Additionally or alternatively, pulse-shaping filtering may be applied to a frequency domain signal to provide a pulse-shaped frequency domain data signal used to generate a reduced PAPR time domain data signal. Other aspects and features are also claimed and described.
