Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may receive a configuration for a first random access message of a two-step random access channel procedure. The wireless device may select a subcarrier spacing and a number of demodulation reference signal occurrences for transmitting the first random access message based at least in part on the configuration and a speed of the wireless device. The wireless device may transmit the first random access message of the two-step random access channel procedure using the subcarrier spacing and the number of demodulation reference signal occurrences.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may receive, from a user equipment (UE), a first random access message of a two-step random access procedure. In some examples, the first random access message may be transmitted by the UE based on one or more cell-specific transmission parameters or cell-specific transmission schemes. The base station may transmit, to the UE, a second random access response message of the two-step random access procedure in response to the first random access message. The second random access response message being transmitted based on one or more cell-specific transmission parameters or cell-specific transmission schemes. Accordingly, the base station and the UE may establish a connection with the UE based on the first random access message and the second random access response message, or the base station can indicate to the UE to return to an inactive mode or idle state.

Abstract: Methods, systems, and devices for wireless communications are described. One or more multiple access-capable user equipments (UEs) may be grouped together for transmitting uplink multiple access communications to a base station, where the UEs may be assigned to the group based on similar capabilities or service requirements. The UE may receive configuration information based at least in part on the group to which the UE has been assigned. When assigned to a group, the UEs may also receive a group-specific scrambling code for the uplink multiple access communications, a group-specific power control for the uplink multiple access communications, time and frequency resources to be used for the uplink multiple access communications specific to the group, or a combination thereof. Additionally, the specific time and frequency resources may be defined by multiple access resource units.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information identifying an offset between a start of a frame on a first component carrier and a start of a frame on a second component carrier, wherein the first component carrier is one of a primary cell (PCell) or a secondary cell (SCell), and wherein the second component carrier is the other of the PCell or the SCell; determine that a slot on the first component carrier is aligned with a slot on the second component carrier; identify the slot on the second component carrier in accordance with the offset; and communicate on the first component carrier or the second component carrier based at least in part on the start of the slot on the second component carrier. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication that a high Doppler configuration is activated. The UE may detect, based at least in part on receiving the indication that the high Doppler configuration is activated, a phase tracking reference signal (PTRS) for a remaining minimum system information (RMSI) communication. The PTRS may be configured by the high Doppler configuration. Numerous other aspects are provided.

Abstract: A reference signal periodically transmitted by a base station in a wireless network can have certain proprietary properties to help prevent detection and utilization of the signal for unauthorized positioning of mobile devices. More specifically, a network node can obscure and introduce time-variation in mapping between positioning signals and a corresponding physical base stations. The network node may also introduce time variations in fields of a base station almanac (BSA) provided to subscribing user equipments (UEs). The information transmitted to the subscribing UEs may be encrypted.

Abstract: Methods, systems, and devices for wireless communication are described. A device may transmit first control signaling indicating a capability for switching between carriers of a group of carriers during uplink communications using carrier aggregation. The group of carriers include three or more carriers that are each associated with different radio frequency bands. The device may receive second control signaling that includes an indication for the device to switch to a subset of carriers of the group of carriers for transmission of an uplink message. The subset of carriers may be associated with a combination of radio frequency bands. The device may transmit the uplink message on at least one of the subset of carriers in accordance with a mapping between the combination of radio frequency bands and the at least one of the subset of carriers, where the mapping is based on the capability.
