Abstract: Methods, systems, and devices for wireless communications are described that support techniques for wireless communications using preconfigured uplink resources. Generally, the described techniques provide for enhancement of communication features including frequency hopping, an uplink control channel, coverage enhancement, timing advance, uplink power control, reconfiguration, a downlink control channel, a downlink data channel, retransmissions, or subcarrier spacing for a UE in idle mode. The UE may receive an uplink resource configuration for uplink communications in idle mode, the uplink resource configuration comprising an indicator associated with allocated resources for the uplink communications in idle mode and a set of parameters. The UE may transmit, while in idle mode, a first uplink transmission associated with a transport block on the allocated resources and according to one or more of the parameters, and monitor for a response to the first uplink transmission.

Abstract: The present disclosure relates to transmitting and receiving improved wake-up signals (WUS) between a base station and a user equipment (UE). The UE can receive a configuration for discontinuous reception (DRX) or extended DRX (eDRX). The UE can also determine whether to monitor for a WUS during a DRX WUS time resource or an eDRX WUS time resource. In some aspects, the UE can determine whether to monitor for the WUS during the DRX WUS time resource or the eDRX WUS time resource based on a duration of a DRX time gap between DRX WUS resources and a paging occasion and an eDRX time gap between eDRX WUS resources and the paging occasion. The base station can configure the UE for DRX or eDRX. The base station can also determine whether to transmit a WUS during a DRX WUS time resource or an eDRX WUS time resource.

Abstract: Certain aspects of the present disclosure provide techniques for sounding reference signal (SRS) frequency hopping enhancements. An example method performed by user equipment generally includes determining a first sounding reference signal (SRS) frequency hopping pattern for transmitting one or more SRSs; determining an antenna switch will occur during the transmission of the one or more SRSs; determining a second SRS frequency hopping pattern for transmitting the one or more SRSs, wherein determining the second SRS frequency hopping pattern comprises using the first SRS frequency hopping pattern to generate the second SRS frequency hopping pattern based on the determined antenna switch; and transmitting a first set of SRSs of the one or more SRSs according to the first SRS frequency hopping pattern and transmitting a second set of SRSs of the one or more SRSs according to the second SRS frequency hopping pattern.

Abstract: Certain aspects of the present disclosure provide techniques for capability information for sounding reference signal (SRS) improvements. An exemplary method generally includes determining a capability of the UE related to additional sounding reference signal (SRS) transmissions in a normal uplink (UL) subframe; transmitting, to a base station (BS), capability information indicating the determined capability of the UE; receiving SRS configuration information, wherein the SRS configuration information is based, at least in part, on the capability information; and transmitting at least one SRS in accordance with the SRS configuration information.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may obtain, via broadcast signaling or UE-specific signaling, an indication of an uplink communications configuration for one or more uplink wireless communications that span a set of one or more transmission time intervals (TTIs). The indication may be based on one or more types of the one or more uplink wireless communications. The UE may determine a duration of time for which an uplink pre-compensation is to be applied to the one or more uplink wireless communications. The duration of time may be based on one or more parameters of the uplink communications configuration. The UE may output the one or more uplink wireless communications within the duration of time with the uplink pre-compensation applied.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may apply a scaling factor to a transport block of a first size, where the scaling factor may increase the transport block from the first size to a second size. The base station may interleave a set of parts of the transport block of the second size across a set of transmission time intervals (TTIs) in accordance with a transport block allocation pattern, where the set of TTIs may be contiguous or separated from each other by one or more intervening intervals. The base station may transmit, to a user equipment, an indication of the transport block allocation pattern applied to the transport block of the second size, and may transmit the set of parts of the transport block of the second size across the set of TTIs in accordance with the transport block allocation pattern.

Abstract: Methods, systems, and devices for wireless communication are described to indicate a transmission scheme configuration for a message and whether the message is a retransmission or new transmission. In a first example, a base station may configure a subset of one or more feedback process identifiers (IDs) for multicast messages. In such cases, if a grant includes a feedback process ID associated with one of the reserved IDs, the message scheduled by the grant may be a retransmission of a multicast message. In a second example, feedback process IDs may be dynamically allocated to multicast or unicast messages via a corresponding grant. A message may be identified as a new transmission or retransmission of a unicast message or multicast message based on a combination of an ID associated with the grant and a new data indicator (NDI) of the grant.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, such as a user equipment (UE) may receive, in an active duration of a multicast discontinuous reception (DRX) cycle, downlink control information indicating resources of a downlink data channel for a multicast message for a plurality of UE. The UE may monitor the indicated resources for the multicast message, as well as transmit, based on the monitoring the indicated resources, a feedback message corresponding to the multicast message. The UE may initiate a multicast feedback timer based on the monitoring the indicated resources for the multicast message, the multicast feedback timer indicating a time for monitoring for a retransmission of the multicast message. The multicast feedback timer may be different than a unicast feedback timer associated with unicast messages for the UE. In some examples, the UE may initiate a multicast retransmission timer following the multicast feedback timer. The multicast retransmission timer may be different than a unicast retransmission timer associated with the unicast messages.

Abstract: A base station may transmit a multicast transmission to a group of user equipments (UEs) that are each configured with a group radio network temporary identifier (G-RNTI). The UEs may be configured to receive the transmission using the same modulation and coding scheme (MCS) and transport block size (TBS) such that the group of UEs may receive the same transmission. In particular, a UE may receive one or more configurations for multicast transmissions, each configuration associated with a G-RNTI. The UE may determine a MCS table for the G-RNTI. The UE may determine a TBS for a multicast transmission based on an overhead value for the G-RNTI. The UE may receive the multicast transmission based on the MCS table and the TBS.

Abstract: Methods, systems, and devices for wireless communications are described to enable a base station to configure additional reference signals, which may be referred to as configured reference signals, to include in a transmission to a user equipment (UE). The UE may transmit a report to the base station, indicating a UE capability for supporting configured reference signals, and the base station may configure a pattern for the configured reference signals. The base station may transmit an indication of the pattern to the UE, where the indication may include one or more characteristics associated with the configured reference signals. The base station may transmit the configured reference signals to the UE according to the pattern, along with one or more baseline reference signals, within an associated transmission. The UE may use the configured reference signals and the baseline reference signals to receive a transmission from the base station.
