Abstract: Some aspects described herein relate to determining a length for a sequence for communicating a signal, determining a reduced length as a largest prime number that is smaller than a fraction of the length, generating a Zadoff-Chu sequence based on the reduced length, extending the Zadoff-Chu sequence to be of the length to generate the sequence of the length, and communicating the signal based on the generated sequence.

Abstract: A spatial multiplexing configuration may enable a user equipment (UE) to spatially multiplex two or more uplink channels of different types for simultaneous transmission. For example, a UE may receive an indication of a spatial multiplexing configuration from a base station. The UE may identify two or more uplink channels for simultaneous transmission on a same component carrier, where each uplink channel may be a different type. In such cases, the UE may spatially multiplex the two or more uplink channels on a same set of time/frequency resources on the component carrier in accordance with the spatial multiplexing configuration. The spatially multiplexed uplink channels may then be simultaneously transmitted by the UE on the set of resources, where the spatially multiplexed uplink channels may be simultaneously sent to the same base station or to different base stations. Additionally, different spatial parameters may be applied to each uplink channel.

Abstract: Methods, systems, and devices for wireless communications are described that provide for service indication via downlink control information (DCI) in which different services have a same DCI size. Techniques provide also that a DCI format may be indicated by a masking operation on a cyclic redundancy check (CRC) of the DCI. The DCI may include an indicator field that may indicate the service of the associated operation. The indication may also be provided via different monitoring occasions of the DCI transmissions that are associated with different services. Different DCI search spaces also may be associated with different services and provide the service indication. Additionally or alternatively, different scrambling sequences used on all or a portion of control information or demodulation reference signal transmissions may be associated with different services.

Abstract: Systems and method for configuring and providing uplink control information (UCI) multiplexing on physical uplink shared channel (PUSCH) transmissions are disclosed. In embodiments, a base station configures and signals, to a user equipment (UE) a plurality of sets of beta-offset values to be used by the UE for multiplexing a UCI transmission of a first priority to a PUSCH transmission of a second priority. Each set of the plurality of sets of beta-offset values is configured based on the second priority of the PUSCH transmission. In embodiments, the UE determines whether the UCI transmission of the first priority is allowed to be multiplexed to the PUSCH transmission of the second priority, and multiplexes the UCI to the PUSCH when multiplexing of the UCI and PUSCH is allowed, using a beta-offset value from the plurality of sets of beta-offset values. Other aspects and features are also claimed and described.

Abstract: Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas associated with different power classes. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. The local and auxiliary antennas may be associated with different power classes, and the first device may transmit a message to a base station indicating that the first device is capable of transmitting using antennas associated with different power classes. The first device may then receive configurations from a base station of different transmit powers to transmit on the antennas associated with the different power classes, and the first device may transmit uplink signals to the base station in accordance with the different transmit power configurations.

Abstract: Wireless communications devices and methods are adapted to facilitate DMRS sequence grouping. In one example, information is obtained for a transmission scheduled with pi/2 BPSK modulation, the transmission including two or more symbols scheduled for a DMRS (DMRS symbols). Respective DMRS sequences may be identified for each of the DMRS symbols, where each DMRS sequence subsequent to another DMRS sequence is dependent on its immediately preceding DMRS sequence, and the transmission may be sent with the identified DMRS sequences in the two or more DMRS symbols. In one example, a first transmission may be sent to schedule a second transmission from another device with pi/2 BPSK modulation, where the second transmission includes two or more DMRS symbols. The scheduled second transmission may be received with at least one DMRS symbol including a DMRS sequence based on its immediately preceding DMRS sequence. Other aspects, embodiments, and features are also included.

Abstract: Certain aspects of the present disclosure provide techniques for scaling transmission power across transmit chains for physical uplink shared channel (PUSCH) transmissions. In some cases, a UE may determine a transmit power budget, receiving signaling indicating how to allocate the transmit power budget across transmit chains for a physical uplink shared channel (PUSCH) transmission, allocate the transmit power budget across transmit chains for a physical uplink shared channel (PUSCH) transmission, and transmitting the PUSCH using the transmit chains according to the determined transmit power allocation.
