Abstract: Methods, systems, and devices for wireless communications are described. For example, a user equipment (UE) may be configured to receive a downlink control message (e.g., an uplink grant) that schedules resources for transmitting repetitions of an uplink channel transmission, where each of the repetitions of the uplink channel transmission may correspond to a single transport block. The UE may determine a plurality of sounding reference signal (SRS) resources based on the downlink control message, and transmit different instances of the uplink channel transmission repetitions according to different SRS resources. The described examples for uplink repetitions may support various techniques for uplink coverage enhancement and diversity gains.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may perform uplink reference signal bundling for access link communications and transmit sidelink communications using time or frequency division multiplexed resources. The UE may determine to drop or to transmit a sidelink communication based on a relationship with multiple instances of an uplink reference signal that are to maintain phase continuity. The UE may drop a sidelink communication when a time duration between two instances of the uplink reference signal is less than or equal to a time threshold value, and may transmit the sidelink communication when the time duration exceeds the time threshold value. In frequency division multiplexed cases, the UE may set a transmission power for each instance of the uplink reference signal, and the sidelink communication may use a remaining amount of power.

Abstract: A UE may enter a dormant state, e.g., for power savings. The systems, methods, and apparatus described herein may provide ways for the UE to transition between an active state and a dormant state, as well as UE behavior in a dormant state. The apparatus may be a UE configured to receive an indication of a bandwidth part (BWP) switch for a secondary cell and to transition between an active state and a dormant state for the secondary cell based on the indication of the BWP switch.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may determine a Physical Uplink Control Channel (PUCCH) resource for a PUCCH transmission prior to receiving a dedicated PUCCH resource configuration, determining a repetition level for the PUCCH transmission, and transmit the PUCCH transmission, on at least the PUCCH resource, according to the repetition level. A base station may transmit, to a user equipment (UE), information scheduling a Physical Uplink Control Channel (PUCCH) transmission on a PUCCH resource prior to configuring dedicated PUCCH resources for the UE, determine a repetition level for the PUCCH transmission, transmit, to the UE, an indication of the repetition level, and receive, according to the repetition level, a first repetition of the PUCCH transmission on the PUCCH resource and other repetitions of the PUCCH transmission.

Abstract: Fallback procedures for user equipments (UEs) are described that provide efficient fallback to a four-step random access procedure from a two-step random access procedure. For example, after transmitting a first message of a two-step random access procedure, a UE may start a fallback timer or counter and monitor for a second message of the two-step random access procedure for the duration of the fallback timer or counter. At the expiration of the fallback timer or counter, the UE may fall back to a four-step random access procedure. In some cases, the UE may transmit multiple repetitions of the first message and monitor for responses after transmitting the repetitions or after each repetition. Additionally, or alternatively, the base station may transmit an explicit signal to the UE that may signal to the UE to perform a fallback procedure at a beginning or middle of a random access procedure.

Abstract: In some aspects, a user equipment (UE) determines a transmission gap adjustment (TGA) for a first message (msgA) of a 2 step random access channel (RACH) procedure based on measurement of a reference signal transmitted by a base station as well as the radio resource configuration (RRC) configurations for msgA. In other aspects, a base station transmits a system information block (SIB) or RRC signaling that indicates at least one possible configuration of the TGA, and UEs determine the TGA depending on RRC state. Connected mode UEs having a timing alignment (TA) timer running may determine the TGA based on a previous TA. UEs in other RRC modes determine the TGA based on the possible configuration transmitted in the SIB or RRC signaling. Advantageously, 2 step RACH UEs are able to communicate with the base station without the closed loop TA information provided by a 4 step RACH.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a first downlink control information (DCI) message indicating the UE is to transmit a transport block over multiple available slots on at least a first carrier and a resource allocation for the transport block. The multiple available slots my span a time interval. The UE may receive, from the base station, a second DCI message indicating the UE is to switch from the first carrier to a second carrier during the interval. Based on the second DCI message, the UE may transmit at least a first portion of coded bits corresponding to the transport block on the first carrier in at least one available slot of the multiple available slots.

Abstract: Wireless positioning accuracy of a user equipment (UE) is impacted by locations of the transmit/receive points (TRPs) and UE for wireless positioning. To improve the accuracy of estimated locations, a geometric dilution of precision (GDOP) may be determined for different groups of candidate TRPs, with the GDOP indicating a potential positioning error associated with the group of candidate TRPs. A UE may determine GDOPs for different combinations of candidate TRPs. One or more devices of a wireless network (e.g., a location server and/or a UE for positioning) may select or exclude one or more candidate TRPs from being used for wireless positioning of a UE based on the determined GDOPs. Exclusion or selection of candidate TRPs for wireless positioning may also be based on quality measurements of PRSs (such as an RSRP or SNR) or a time duration associated with measuring the PRSs from the candidate TRPs to be selected.

Abstract: A configuration to enable a UE to monitor downlink control to determine a slot direction while operating in a half duplex operation in a FDD mode. The apparatus receives an indication of a slot pattern for a plurality of slots, wherein the slot pattern indicates the plurality of slots includes at least one flexible slot. The apparatus receives a downlink control monitoring occasion configuration. The apparatus monitors for downlink control from a base station based at least on the indication of the slot pattern and on the monitoring occasion configuration. The apparatus determines whether the at least one flexible slot is an uplink slot or a downlink slot based on a DCI. The apparatus transmits or receives communications on the slot based on the determination.

Abstract: Methods, systems, and devices for wireless communication are described to support phase continuity in uplink transmissions within a bundle interval. In a first example, a user equipment (UE) may determine bundle intervals for an uplink channel transmission based on a transmission time interval (TTI) format pattern and a bundle size. Bundle intervals may start on a next available uplink TTI after an end of a preceding bundle interval, such that each bundle interval may include at least one uplink TTI. In a second example, the UE may use frequency resources for repetitions of the uplink channel transmission within a bundle interval based on an index of the bundle interval. In a third example, the UE may not bundle some repetitions of the uplink channel transmission in a same bundle interval, and may use different frequency resources for the repetitions, based on one or more phase continuity rules.
