Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to reference signal design for Pi/2-binary phase shift keying (Pi/2-BPSK) modulation with frequency domain spectral shaping (FDSS). In certain aspects, a method includes generating a set of Gold sequences each having a length and adjusting the length of each of the Gold sequences in the set of Gold sequences. The method also includes applying a phase rotation to each of the Gold sequences in the set of Gold sequences and modulating each of the Gold sequences in the set of Gold sequences by a DFT-s-OFDM with frequency domain spectral shaping (FDSS). The method further includes selecting one or more sequences from the set of modulated Gold sequences based on a parameter and transmitting the one or more sequences to a user equipment (UE) or a base station (BS).

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform a calibration to improve the accuracy, reliability, or both of signal transmissions. The UE may determine timing for the calibration procedure based on a received identifier for the UE (e.g., a radio network temporary identifier (RNTI), such as a cell RNTI (C-RNTI)). For example, the UE may determine a calibration offset between a reference time and a calibration gap according to an equation using at least the identifier as input. During the calibration gap, the UE may transmit a calibration signal using one or more antenna ports and may calibrate (e.g., adjust power amplification for) the one or more antenna ports based on an estimated actual transmit power for the calibration signal (e.g., received by other antenna ports of the UE or received by another device).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of bandwidth part (BWP) combinations for an inter-band carrier aggregation configuration in a frequency range above 24 GHz. The UE may transmit an indication of the set of BWP combinations to initiate a reconfiguration of a BWP combination for the UE. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques and devices for uplink gap configuration and determination of uplink resources after uplink gap distribution. Certain aspects are directed to an apparatus for wireless communications at a user equipment (UE). The UE may include a memory comprising instructions, and one or more processors configured to execute the instructions. In some examples, the instructions may cause the apparatus to obtain, from a base station, an uplink gap pattern (ULGP) configuration indicating a first ULGP associated with a first time window, wherein the first ULGP is indicative of a distribution of one or more uplink slots activated as uplink gaps within the first time window, and wherein the one or more uplink slots are independent from being used for any transmission initiated by the apparatus.

Abstract: Methods, systems, and devices for enhanced carrier aggregation techniques described. For example, component carrier groups including multiple component carriers may be configured. In some cases, each component carrier group may be configured to include 2n component carriers. Also, component carriers may be managed on a per component carrier group basis. In some cases, a single management message may be used to communicate management information for a component carrier group. Similarly, a single control message may be used to communicate control information, such as physical layer parameters, for a component carrier group.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that uplink communications are to be performed between the UE and a first cell group associated with a first radio access technology (RAT) and between the UE and a second cell group associated with a second RAT. The UE may determine that the UE is configured for power sharing for the uplink communications with the first cell group associated with the first RAT and the second cell group associated with the second RAT. The UE may calculate, based on the power sharing and the uplink communications, a power reduction factor for the uplink communications between the UE and the second cell group. The UE may perform the uplink communications with the first cell group and selectively perform the uplink communications with the second cell group.

A user equipment (UE) may determine that uplink communications are to be performed between the UE and a first cell group associated with a first radio access technology (RAT) and between the UE and a second cell group associated with a second RAT. The UE may determine that the UE is configured for power sharing for the uplink communications with the first cell group associated with the first RAT and the second cell group associated with the second RAT. The UE may calculate, based at least in part on the power sharing and the uplink communications, a power reduction factor for the uplink communications between the UE and the second cell group. The UE may perform the uplink communications with the first cell group and selectively perform the uplink communications with the second cell group.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for providing beam switch latency using communications systems operating according to new radio (NR) technologies. For example, the method generally includes determining a latency associated with a beam switch from a source antenna array module to a target antenna array module when the target module is in a low power mode; and signaling a base station to use the determined latency after sending a command for the beam switch.
