Abstract: Systems, methods, and devices for wireless communication that support mechanisms for uplink carrier selection for uplink random access channel (RACH) transmissions in a flexible cell configuration in a wireless communication system. A user equipment (UE) in a flexible cell selects at least one carrier for transmitting one or more uplink RACH transmissions to a base station. In aspects, the base station transmits an indication to the UE indicating which carrier the UE is to select for transmitting the one or more uplink RACH transmission. In aspects, the UE determines the carrier to transmit the one or more uplink RACH transmissions to the base station based on a comparison of reference signal measurements to predetermined thresholds. In these aspects, based on whether the measurements exceed the predetermined thresholds or not, the UE selects a carrier for transmitting the one or more uplink RACH transmission to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may attempt to connect to a base station using a random access procedure. During the random access procedure, the base station may transmit control information associated with a random access response (RAR) during a RAR window. The UE may attempt to receive a single instance of the control information and, in some cases, may be unable to receive and decode the single instance of the control information. The base station may configure one or more RAR windows (or segment(s) thereof) to support transmitting repeating instances of the control information and/or RAR. The UE may identify a quantity of instances of the repeated control information and combine the instances. The UE may successfully decode the combined instances of control information and identify a location for receiving the RAR.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, signaling indicating a channel state information (CSI) report configuration. The CSI report configuration may indicate a mapping between one or more CSI reference signal (CSI-RS) resources for use in a dormancy state for one or more secondary cells and at least one antenna panel configuration of the base station. Based on the configuration, the UE may receive one or more CSI-RSs on the CSI-RS resources of the one or more dormant secondary cells. In some cases, the UE may receive an antenna adaptation indication based on monitoring a downlink control channel. Additionally or alternatively, the UE may receive scheduling information for a downlink shared channel containing an antenna adaptation indication. The UE may transmit a message reporting CSI feedback to the base station in accordance with the antenna adaptation indication.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may receive reference signals from another wireless device over a channel between the devices. The wireless device may perform channel estimation based on the reference signals to determine multiple taps. The wireless device may receive a message from the other wireless device indicating one or more taps to be selected to obtain a secret key for encrypting a message. The wireless device may select the taps based on the indication and communicate one or more encrypted messages with the other wireless device. For example, the wireless device may receive encrypted messages, transmit encrypted messages, or both.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes establishing a first component carrier as a primary cell for the user equipment (UE) and a second component carrier as a secondary cell for the UE, receiving primary cell configuration information for the second component carrier while the second component carrier is the secondary cell for the UE, receiving a control message triggering a switch of the primary cell from the first component carrier to the second component carrier, and establishing the second component carrier as the primary cell for the UE based on the control message and in accordance with the primary cell configuration information associated with the second component carrier.

Abstract: Disclosed are techniques for wireless communication. In an aspect, BS determines a channel state information (CSI) report field priority-based security scheme, and transmits CSI report field priority-based security scheme to UE. UE determines bit availability in CI (e.g., UCI or SCI or MAC CE) for transmission of a CSI report. UE configures, based on the CSI report field priority-based security scheme and the CI bit availability, the CSI report with first field(s) (e.g., secured with key) being secured via a key and second field(s) being unsecured (e.g., not secured with any key or secured with weaker key below strength threshold). UE transmits the CSI report to BS.

Abstract: Disclosed are various techniques for wireless positioning. In an aspect, the time that a user equipment (UE) spends on performing positioning reference signal (PRS) measurements is reduced, by lengthening the PRS measurement period (P) and/or by reducing the PRS symbol duration (K). These modifications may be performed by the UE or by a location management server or other network node and may be made in consideration of the UE's mobility status and other environmental or operating conditions of the UE. In an aspect, a network entity may determine P and K to be used by the UE, and may indicate, to the UE, the P and the K to be used by the UE for measuring at least one PRS. The UE may then use the P and the K for measuring at least one PRS.

Abstract: Aspects are provided allowing a UE to perform early termination of repetitions of an ongoing PUSCH transmission in response to a DCI from a base station indicating whether a prior PUSCH transmission or repetition was successfully decoded. The UE obtains information configuring an uplink data transmission and a repetition of the uplink data transmission. The UE sends the uplink data transmission to a base station. The UE terminates the repetition of the uplink data transmission in response to reception of downlink information in a downlink control channel. Thus, UE power reduction and enhanced resource efficiency may be achieved. Moreover, the repetition is terminated after a time gap following a CORESET where the downlink control channel is received. As a result, a start time for terminating PUSCH repetitions may be configured to accommodate various timing considerations such as dynamic TDD, different numerologies between PDCCH and PUSCH, and multiple PUSCH processing capabilities.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, signaling indicating a channel state information (CSI) report configuration. The CSI report configuration may indicate a mapping between one or more CSI reference signal (CSI-RS) resources or one or more CSI-RS port groups and one or more antenna panels or antenna subpanels of the base station. The UE may generate CSI feedback based on the mapping. In some cases, the UE may generate the CSI feedback based on multiple hypotheses that correspond to CSI-RS measurements. In some examples, the multiple hypotheses may include a set of hypothesis groups based on one or more antenna panels or antenna subpanels of the base station. The UE may transmit a message reporting the CSI feedback to the base station.
