Abstract: Methods, systems, and devices for wireless communications that support power control in full duplex communication are described. In some wireless communications systems, a user equipment (UE) may experience antenna isolation for communication of downlink and uplink data traffic. Based on the antenna isolation, the UE may realize an increased channel capacity for full-duplex communication. As part of the full-duplex communication, the UE may identify characteristics of a potential downlink signal on formatted slots of the channel. The UE may determine an uplink transmit power control configured to account for the characteristics. The determination may include a configured transmit power control for beamformed signaling at the UE, and may be based on signal reception quality for potential downlink transmissions. Based on the determination, the UE may either perform uplink transmission on a resource block allocation of the formatted slots or forgo uplink transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indicator of a feedback window that is offset relative to a beginning transmission time interval (TTI) of a set of consecutive TTIs. The consecutive TTIs may include a set of aggregated slots or may correspond to a multi-TTI grant. The feedback window may include multiple control channel occasions interspersed within a duration of the set of consecutive TTIs. The UE may receive a transport block within a first TTI of the set of consecutive TTIs and transmit, within a control channel, feedback to indicate whether the transport block was successfully received.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to cell recovery techniques. One example method generally includes receiving, at a user-equipment (UE), at least one pilot signal via a secondary cell, receive, via a primary cell, a first message triggering reporting of at least one preferred beam for communication via the secondary cell, determining the preferred beam based on the at least one pilot signal, transmitting, via the primary cell, a report indicating the at least one preferred beam, and communicating data via the secondary cell and via the preferred beam.

Abstract: Certain aspects of the present disclosure provide techniques for switching control beams in multi-link systems using new radio (NR) technology multiple-input multiple-output (MIMO) techniques. A user equipment (UE) may obtain a configuration from a base station (BS) comprising at least one first pattern of beams to monitor when performing a beam recovery procedure, communicate using beamforming, with the BS, via an active transmit and receive beam pair, determine a beam failure of the active transmit and receive beam pair, and monitor the beams according to the first pattern in response to the beam failure.

Abstract: Techniques are described herein for beam pair link procedures used in dual connectivity operations. A master base station may be configured to determine a timing window for a user equipment (UE) to monitor a downlink channel associated with a secondary base station. In some cases, the master base station may determine the timing window during a dual connectivity procedure or during a carrier aggregation procedure. The UE may monitor the downlink channel during the timing window and establish a beam pair link with the secondary base station based on the monitoring.

Abstract: Methods, systems, and devices for wireless communications are described that provide staggered synchronization signal blocks (SSBs) in frequency sub-bands for beamformed wireless communications. Transmissions of SSBs and control channel transmissions (e.g., remaining minimum system information (RMSI) physical downlink control channel (PDCCH) transmissions) may use multiple transmission beams in a beam sweeping procedure. The SSB transmissions may be transmitted using transmission beams that span one frequency sub-band of a number of available frequency sub-bands, and the control channel transmissions may use transmission beams that span two or more of the frequency sub-bands. The SSB beam sweeping procedure may be performed separately during staggered, non-overlapping time periods for each frequency sub-band of the number of frequency sub-bands. Each of the of SSBs may indicate a reference timing of the base station used to identify a set of resources (e.g., a control resource set (CORESET)) that carries control channel transmissions.

Abstract: This disclosure generally relates to systems, devices, apparatuses, products, and methods for wireless communication. A communication system may include a user equipment (UE) that receives a configuration for contention-free random access (CFRA) and a configuration for contention-based random access (CBRA). The UE determines a first random access resource. The first random access resource maps to one or more beams from a target base station. The UE determines a beam quality associated with the first random access resource. The UE initiates a random access request using the CFRA when the first random access resource is a contention-free resource, and the beam quality of the first random access resource is above a threshold beam quality. The UE initiates the random access request using the CBRA when the first random access resource is the contention-free resource, and the beam quality of the first random access resource is below the threshold beam quality.

Abstract: Aspects of the present disclosure provide techniques for tunneling control information associated with random access procedure (RACH) from a fifth generation (5G) new radio (NR) base station (e.g., secondary base station (SgNB)) to the user equipment (UE) via long term evolution (LTE) master base station (e.g., “MeNB”) in order to extend the coverage of the SgNB. The tunneled PDCCH control information may include one or more of frequency domain resource assignment, time domain resource assignment (e.g., physical downlink shared channel (PDSCH) scheduled slot index, start symbol index and duration in the slow), and/or modulation coding scheme (MCS).
