Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for multiple downlink control information (DCI) message handling for multiple control resource set (CORESET) groups. In one aspect, a user equipment (UE) may provide separate or joint feedback for data messages received from different CORESET groups. In some examples, the UE may be configured with code block group (CBG)-based transmissions for a component carrier (CC) or a CORESET group in a CC. If implementing a dynamic codebook, the UE may track separate transport block (TB)-based and CBG-based downlink assignment indexes (DAIs) for each CORESET group or may track joint TB-based and CBG-based DAIs across the set of CORESET groups to handle the CBG configuration. Additionally, or alternatively, if implementing a semi-static codebook, the UE may apply skipping rules across the set of CORESET groups or separately for each CORESET group to reduce signaling overhead.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support multi-band operation. Different frequency bands may experience different communication characteristics (e.g., frequency-dependent fading), which may result in undesirable interference patterns and/or coverage gaps. The described techniques provide for discovery procedures for multi-band operation. The discovery procedures may allow for improved throughput, improved energy efficiency, reduced signaling overhead, as well as other benefits for a wireless communications system. Generally, the described techniques provide for efficient discovery reference signal (DRS) transmissions over multiple frequency bands. The timing of the DRS transmissions across the different bands may be related or the DRS transmission timing for each band may be determined independently.

Further, when continuous precoding is applied to an RB cluster, the transmitting device may explicitly or implicitly signal the dynamic control over one or more transmission properties, with an aim to maximize the benefits of such continuous precoding. Other aspects, embodiments, and features are also claimed and described.

Abstract: Some techniques and apparatuses described herein protect components of a user equipment (UE), such as a low noise amplifier (LNA), from internal interference. For example, the LNA may be disconnected from a receive chain during periods of high internal interference, and may be reconnected to the receive chain during periods of low internal interference. Furthermore, some techniques and apparatuses described herein improve performance by adjusting operations of the UE to account for and/or offset increased internal interference due to a receive chain that does not include a surface acoustic wave (SAW) filter to remove unwanted radio frequency signals. For example, one or more operations of a baseband processor may be modified to account for the increased internal interference. Additionally, or alternatively, reporting of channel state information may be modified to account for increased internal interference of the UE. Additional details are described herein.

Abstract: Methods, systems, and devices for wireless communication are described. To encode a vector of bits using a polar code, an encoder may allocate information bits of the vector to polarized bit-channels associated with a channel (e.g., a set of unpolarized bit-channels) used for a transmission. In some cases, the polarized bit-channels may be partitioned into groups associated with different values of some associated reliability metric (s). The information bits may be allocated to the polarized bit-channels based on the reliability metrics of the different polarized bit-channels and the overall capacity of a transmission. That is, the bit locations of a transmission may depend on the reliability metrics of different polarized bit-channels and the overall capacity of the transmission. To facilitate puncturing, the overall capacity of the transmission may be adjusted and the unpolarized bit-channels may be partitioned into polarized bit-channels based on the adjusted capacity.

Abstract: A mobile device supports positioning with positioning reference signals (PRS) on multiple beam by dividing the PRS processing into two separate modes, an acquisition mode and a tracking mode. In acquisition mode, the mobile device performs a fast scan of all of the beams from a base station transmitting PRS using less than the full set of resources for the PRS, i.e., less than the full bandwidth and/or less than the full number of repetitions of the PRS. The mobile device may select the best beams to use for positioning, e.g., based on signal strength metric. In tracking mode, the mobile device tracks the PRS from only the selected beams using the full set of resources for the PRS. The mobile device may return to acquisition mode after a predetermined number of positioning occasions or if the selected beams are no longer valid due to movement or change in conditions.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify uplink (UL) control information (UCI) to transmit during a subframe. The UE may then select a UL channel on which to transmit the UCI based on whether a shared data and control UL channel employs contention-based scheduling. For example, multiple UEs could contend for access to the same semi-persistently scheduled (SPS) physical UL shared channel (PUSCH). Each UE may utilize a different demodulation reference (DMRS) signal cyclic shift to identify their transmissions. In some cases, some UCI, such as channel state information (CSI), may be transmitted on a contention-based PUSCH, while other UCI, such as acknowledgement information, may be transmitted on a physical uplink control channel (PUCCH). In some cases, the channel selection may be based on a configuration received from a base station.
