Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may process, for a physical uplink control channel (PUCCH) communication in a millimeter wave (mmWave) band, information for transmission, wherein the information is modulated using an extended sequence with a length greater than a base sequence length for PUCCH communication or wherein a cyclic shift, of a plurality of cyclic shifts for a set of contiguous resource blocks for transmission of the information, is applied to the information based at least in part on a resource block group associated with the information. The UE may transmit the information based at least in part on processing the information. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. One method for coverage enhancement may include a base station transmitting control signaling to one or more user equipments (UEs) using a same beam configuration to perform a coverage enhancement procedure for uplink transmissions. In response, one or more UEs may determine one or more transmission parameters for uplink transmission based on the coverage enhancement procedure. In some cases, the coverage enhancement procedure may include the UEs transmitting additional repetitions of an uplink transmission, using additional time or frequency resources, or any combination thereof. In some cases, the UEs may use different coverage enhancement procedures. Accordingly, the one or more UEs may transmit an uplink transmission based on the one or more transmission parameters.

Abstract: Methods, systems, and devices for wireless communications are described in which control resources may be identified, and a data transmission may be rate-matched around the one or more control channels of multiple UEs or at multiple aggregation levels in the control resources. A user equipment (UE) may identify a search space for a first control channel, and the rate-matching of the data transmission may be performed based on a location of the search space in the control resources. In some cases, a base station may provide a mapping of resources (e.g., a bitmap) within the control resources that are occupied, which may be used for rate-matching.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may obtain updated location information, and determine a time difference between a previous communication with a network and a scheduled uplink transmission. Based on the determined time difference, the UE may determine a timing advance (TA) component of a TA value to apply for the uplink transmission, and transmit an uplink message in the uplink transmission according to the determined TA value and the location information. In some examples, the time difference may be based on a first duration between the uplink transmission and a previous uplink transmission, a second duration between the uplink transmission and a previous TA command received from the network, or both. In some examples, the determined TA value may be based on additional parameters, such as an autonomous adjustment step, an aggregate adjustment rate, a scaling factor, or any combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a user equipment (UE) may transmit, to a base station, an indication of a capability of the UE to switch from monitoring a set of frequency resources according to a first subcarrier spacing (SCS) to monitoring the set of frequency resources according to a second SCS, less than the first SCS. The indication may indicate an amount of time for the UE to switch between SCSs. The UE may receive, from the base station, signaling that indicates a configuration for monitoring the set of frequency resources according to the second SCS (e.g., a configuration for a reduced SCS window). The UE may switch from monitoring the set of frequency resources according to the first SCS to monitoring the set of frequency resources according to the second SCS based on receiving the configuration for monitoring the set of frequency resources.

Abstract: A method of wireless communication performed by a first transmission and reception point (TRP), includes receiving a message indicating a measurement of a reference signal (RS) transmitted in a first band to a wireless device or one or more features of a second band estimated by the wireless device. The first TRP may operate in the second band not overlapping the first band, the one or more features comprise one or more of a channel characteristic, a signal strength, or a beam direction of the second band. The method also includes adjusting one or more parameters of the second band in response to receiving the message. The one or more parameters may include one or both of a channel or a beam direction. The method further includes transmitting signals to a user equipment (UE) in the second band according to the one or more adjusted parameters.

Abstract: Techniques are described for supporting user equipment (UE) positioning in a non-terrestrial network (NTN). To allow calculating a position/location of a UE based on reference signal (RS) measurements to and from one satellite (or a terrestrial base station), a device may be configured to calculate a doppler measurement and a range measurement and report such measurements to be used by a location server to calculate a UE position. An example device may receive a first RS (with the first RS being one of a positioning reference signal (PRS) or a sounding reference signal (SRS)), receive a second RS associated with the first RS, calculate a doppler measurement based on one or both of the first RS or the second RS, and report the doppler measurement. The doppler measurement (such as a measured frequency offset) may be used by a location server to calculate a UE position on the earth surface.

Abstract: Certain aspects of the subject matter described in this disclosure can be implemented in a method for wireless communication by a user equipment (UE). The method generally includes receiving, from a network entity, signaling that schedules an uplink or downlink transmission on resources that overlap with a time gap for switching from a first set of frequency resources to a second set of frequency resources; and taking an action to process the uplink or downlink transmission so that the uplink or downlink transmission does not overlap with the time gap.

Abstract: Aspects relate to configuration of a Layer 1 (L1) measurement report. A radio access network (RAN) node (e.g., a base station) can transmit at least one report setting, each associated with a selected information type, to a wireless communication device (e.g., a UE). The selected information type may be selected from a first information type and a second information type. When a report setting is associated with the first information type, the wireless communication device can transmit the L1 measurement report including both beam measurements and beam identifiers corresponding to the beam measurements for the report setting. When the report setting is associated with the second information type, the wireless communication device can exclude the beam identifiers from the L1 measurement report including the beam measurements for the report setting. Other aspects, features, and examples are also claimed and described.
