Abstract: The present disclosure relates to wireless communication in mmW networks. The apparatus may be a base station. The apparatus may be configured to determine a first symbol index and a second symbol index associated with downlink resources allocated to a UE. The first symbol index may indicate when the downlink resources begin in a subframe, and the second symbol index may indicate when the downlink resources end in the subframe. The apparatus may be configured to transmit an indication of the first symbol index and the second symbol index to the UE.

Abstract: Certain aspects of the present disclosure provide techniques for wake-up resource randomization for discontinuous reception operation. An example method generally includes obtaining configuration information for receiving at least one wake up signal (WUS) during an OFF duration of a discontinuous reception (DRX) mode of the UE; monitoring, during a WUS monitoring occasion occurring during the OFF duration of the DRX mode, the one or more resources for the at least one WUS based on the configuration information; and transitioning to an ON state of the DRX mode when the at least one WUS is detected in the one or more resources during the monitoring; or remaining in an OFF state of the DRX mode when the at least one WUS is not detected in the one or more resources during the monitoring.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently identifying spatial parameters for receiving control information in an initial coreset. In one example, a user equipment (UE) may receive a TCI state indicating reference signals quasi co-located with a control information transmission in a coreset, and the UE may also identify a quasi co-location (QCL) assumption in a random-access procedure indicating that a synchronization signal block (SSB) is quasi co-located with the control information transmission in the coreset. In this example, the UE may identify spatial parameters for monitoring the coreset for the control information transmission in accordance with the TCI state or the QCL assumption based on the timing of the indicated TCI state and the QCL assumption.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a configuration indicating a transmission configuration indicator (TCI) state switching pattern and a TCI state switching period to a user equipment (UE). The UE may perform TCI state switching according to the TCI state switching pattern and period, and the UE may receive a downlink transmission according to the TCI state switching pattern. The UE may receive a downlink control information (DCI) including an indication of a TCI state for a subsequent TTI. The UE may receive the downlink signal in accordance with both the TCI state switching pattern and the indication in the DCI. The UE may receive a configuration message indicating a first DCI state, receive a DCI indicating a second TCI state for a subsequent TTI, switch to the second TCI state, and receive a downlink signal using the second TCI state.

Abstract: Methods, systems, and devices for using a common physical downlink control channel (PDCCH) to indicate transmission beams to be used by a base station during a transmission opportunity or a periodicity to monitor search spaces are described. A user equipment (UE) may monitor a search space (in some cases, using a periodicity) for the common PDCCH to determine if transmission beams associated with the UE are to be used during the transmission opportunity. If so, the UE may wake-up during at least a portion of the transmission opportunity to receive additional information. If the common PDCCH indicates that no transmission beams associated with the UE are to be used during the transmission opportunity, the UE may enter or re-enter the sleep state. The UE may switch to a new periodicity for monitoring the search space based on the information transmitted within the common PDCCH.

Abstract: Aspects of the present disclosure provide various flexible search space designs that can handle UEs with various capabilities and limitations. In some aspects of the disclosure, the downlink bandwidth may be divided into several self-contained sub-bands. Each sub-band may include one or more OFDM subcarriers or tones, and each UE may be configured to monitor one or more of the sub-bands for its downlink control channel. The sub-band is self-contained in such a way that each sub-band includes CCEs that are mapped to resource elements contained in the same sub-band. In some aspects of the disclosure, different sub-bands can be configured with the different transmission modes and pilot densities. The transmission mode, pilot density, and layer-ID may be determined as a function of each UE's search space.
