Abstract: The present disclosure provides for adaptive resource management in new radio operations that favors the usage of resources for pilot signals and channel estimation in the transition slots of a slot burst, and the transmission of data in the subsequent slots of the slot burst. A device such as a user equipment (UE) and/or a base station may determine that the UE is operating in a transition state. The device may adapt a first numerology including a first number of symbols per slot used for transmission in the transition slots during the transition state, to a second scaled numerology including a second number of symbols per slot used for transmission in the subsequent slots after the transition state. A ratio of reference signal symbols to data symbol symbols may be greater in the transition slots than in the subsequent slots.

Abstract: The present disclosure relates to mitigating collision between reference signals and direct current subcarriers both occupying at least a same resource element of a resource block. Specifically, a UE may at least adjust a DMRS pattern within the resource block based on determining an upcoming occurrence of the collision between the DMRS and the DC subcarrier. Further, a network entity may determine that the UE should transmit the DMRS according to an adjusted DMRS pattern and transmit the adjusted DMRS pattern to the UE on a downlink communication channel.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as a user equipment (UE), may determine a capability relating to an antenna configuration associated with channel state information reporting. The UE may transmit a message including an indication of the capability, and receive a channel state information reference signal using the antenna configuration. The UE may transmit, based on the channel state information reference signal, a channel state information report in accordance with the antenna configuration associated with the channel state information reporting.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, via a first component carrier, control information that triggers transmission of an aperiodic reference signal in a second component carrier. The UE may identify a quasi co-location (QCL) assumption for reception of the aperiodic reference signal in the second component carrier based at least in part on a control resource set not being configured for the second component carrier. The UE may then monitor for the aperiodic reference signal of the second component carrier based on the QCL assumption. In some cases, the UE may transmit a measurement report to a base station based on a measurement of the reference signal.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication from a base station to transmit one or more sounding reference signals (SRSs) on respective component carriers (CCs). Each CC may be associated with a different numerology and the UE may determine a transmission timing between reception of the indication and transmission of each of the SRSs based on the numerology for the CC used for transmission. In some cases, the UE may determine the transmission timings based on time durations associated with each numerology, which may be based on a number of symbols for the numerology, a corresponding time between receiving the indication and transmitting uplink data (e.g., SRS), or a combination thereof. The UE may transmit, to the base station, each SRS according to the determined transmission timings.

Abstract: Wireless communication devices are adapted to facilitate multiplexing of signals. According to one example, a wireless communication device can multiplex a first signal and a second signal for transmission across a first resource element and a second resource element. The first resource element may utilize a first subcarrier in a first symbol employing a first numerology. The second resource element may utilize a second subcarrier in a second symbol employing a second numerology that is different from the first numerology, where the second subcarrier overlaps in frequency at least a portion of the first subcarrier. The first and second symbols including the multiplexed first and second signals may subsequently be transmitted. Other aspects, embodiments, and features are also included.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving, from a first base station, a set of cross-link interference measurement configurations associated with location information, performing a cross-link interference measurement procedure on signals received based on the set of cross-link interference measurement configurations, or the location information, or a location of the first UE, or a combination thereof, and transmitting, to the first base station, a measurement value based on the performed cross-link interference measurement procedure.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently reporting channel state feedback for a set of subbands. As an example, a user equipment (UE) may receive a set of reference signals on the set of subbands and determine a respective channel quality indicator (CQI) index for each of the set of subbands based on the reference signals. The UE may then transmit indications of CQI indices for different subbands of the set using variable length indications, such as indications that include different numbers of bits. Since, in some examples, a small length or number of bits may be allocated for reporting CQI indices with a high probability of being reported, overhead in a wireless communications system may be reduced.

Abstract: Methods, systems, and devices for wireless communications are described. According to one or more aspects, a user equipment (UE) may identify, for a set of time periods associated with a reference signal associated with a physical downlink shared channel, an overlap between a first set of frequency resources allocated for the reference signal and a second set of frequency resources that are scheduled to puncture the first set of resources and that are unavailable for scheduling on the physical downlink shared channel. The UE may determine a remaining set of frequency resources from the first set of frequency resources based on the overlap, and a subset of frequency resources from the remaining set of frequency resources based on a reference signal processing configuration. The UE may then process the reference signal in the subset of frequency resources based on the reference signal processing configuration.

Abstract: Techniques and apparatuses described herein permit selective multiplexing of synchronization signal blocks (SSBs), inside of or outside of an SSB measurement timing configuration (SMTC) window, and downlink channel communications depending on one or more factors, which may increase spectral efficiency due to multiplexing when permitted, and may prevent or reduce collisions and interference when not permitted (e.g., due to quasi co-location constraints, processing constraints, timeline constraints, and/or the like).
