Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a baseline physical downlink control channel (PDCCH) monitoring capability of the UE and an enhanced PDCCH monitoring capability of the UE, where the enhanced PDCCH monitoring capability facilitates monitoring by the UE of more PDCCH monitoring opportunities per slot than the baseline PDCCH monitoring capability. The UE may report, to a base station, the enhanced PDCCH monitoring capability and also the baseline PDCCH monitoring capability. The UE may receive, based on the UE reporting the enhanced PDCCH monitoring capability, at least one control resource set configuration that includes an indication that a corresponding control resource set is configured for enhanced PDCCH monitoring. The UE may monitor the corresponding control resource set in accordance with the enhanced PDCCH monitoring capability of the UE.

Abstract: Methods, systems, and devices for wireless communications are described. According to one or more aspects, a user equipment (UE) may receive a configuration message from a base station. The configuration message may configure the UE based on one or more identifiers associated with a group of UEs. The UE may determine at least one identifier based on receiving the configuration message, and may monitor a signal based on the at least one identifier. In some cases, the signal may indicate whether the UE should skip an upcoming duration associated with a discontinuous reception. The UE may then communicate with the base station, based on monitoring the signal.

Abstract: Methods, systems, and devices for wireless communication are described. In some cases, due to blind decoding and channel estimation (CE) limits, one or more user equipment (UE) specific search sets may be pruned for blind decoding and/or CE purposes. For instance, after hashing a set of common decoding candidates to control channel elements (CCEs) within the control region, the UE specific search sets may be pruned so as to conform to the blind decode limitation, since a common search space has already occupied a portion of the total blind decode limit. Following pruning, the UE may hash the sets of UE-specific decoding candidates associated with the one or more UE specific search sets to CCEs within the control region. The UE may further prune UE specific search sets, based on CE limits, while reusing CE for overlapping hashed locations.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may identify a time division duplexing (TDD) configuration, where the TDD configuration includes a symbol pattern for a slot. A network may determine an overlap between a downlink symbol or a flexible symbol and an uplink symbol during symbols of the slot based on a second TDD configuration of a second UE, resulting in a cross-link interference (CLI). The second UE may measure the CLI based on implicit or explicit configurations that enable the measurement. Additionally or alternatively, the second UE may measure the CLI based on uplink signaling used for measuring the CLI, including dedicated signaling used for measuring CLI. In some cases, the uplink signaling may include uplink data, CLI reference signals, or random data.

Abstract: Methods, systems, and devices for wireless communications are described. A core network may organize a set of base stations into a set of cell groups, each cell group including one or more base stations, the cell groups being organized based on potential of each base station to cause interference, by downlink transmission, to reception of uplink transmissions at remote base stations. The core network may identify cell group identifications for each cell group and configure the set of base stations with respective cell group identifications so that signals transmitted from individual base stations of each cell group include the respective cell group identification, and so that remote base stations whose uplink transmissions are interfered with can identify the cell group of base stations causing the interference. The number of base stations in a cell group may be iteratively reduced based on identifying the interference.

Abstract: Rate-matching and channel estimation are disclosed for new radio (NR) user equipments (UEs). An NR UE obtains coexistence information of neighboring legacy operations including common reference signal (CRS) ports, CRS frequency pattern, and a legacy subframe type corresponding to the NR transmission segments. The NR UE determines legacy CRS occasion(s) coinciding with shared downlink direction operations for the NR and legacy operations, and rate-matches reception of NR downlink transmissions around the CRS occasion(s). In other aspects, an NR UE detects overlap of a downlink signal with downlink control channel candidate of a configured control resource set (CORESET). The UE ends monitoring of the candidate within a search space of the CORESET in response to the detected overlap, detects a collision between a scheduled demodulation reference signal (DMRS) and the downlink signal occasion, and discards all or part of the CORESET.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a first plurality of control resources associated with a first transceiver node and a second plurality of control resources associated with a second transceiver node. The UE may select, based at least in part on a decoding limit for the UE, a decoding configuration to use for decoding one or more control resources from the first plurality of control resources and one or more resources from the second plurality of control resources. The UE may decode control signals received over control resources from the first plurality of control resources and the second plurality of control resources according to the decoding configuration.

Abstract: Aspects of frequency error detection with Physical Broadcast CHannel (PBCH) frequency hypothesis are described. For example, a method and apparatus are disclosed for frequency tracking in a user equipment (UE) may include detecting a change in frequency that exceeds a pull-in range of a frequency tracking loop (FTL) of the UE. The method and apparatus may also include identifying a tracking recovery frequency in response to the change in frequency being detected, wherein the tracking recover frequency is identified from a set of frequency hypotheses and based on decoding of the PBCH received by the UE. The method and apparatus may further include updating the FTL with the tracking recovery frequency.

Abstract: A method for speeding up a filter tracking speed includes scaling filter coefficients based at least in part on an uplink/downlink configuration in a time division duplex (TDD) or a multimedia broadcast single frequency network (MBSFN) system. The method also includes applying scaled filter coefficients during at least one downlink subframe to control a filter tracking speed.

Abstract: Systems and techniques are provided for wireless communications performed at a network entity. For example, the systems and techniques can include obtaining, at the network entity, a target relative time difference (RTD). A transmission timing pre-compensation can be determined at the network entity between a first reference signal and a second reference signal, wherein the transmission timing pre-compensation is determined based on the target RTD and one or more network delay components. The first reference signal and the second reference signal can be transmitted using the transmission timing pre-compensation to offset the first reference signal from the second reference signal by the target RTD.
