Abstract: Frequency-selective single frequency network (SFN) operation is disclosed based on a modified Type-II port selection codebook. Within the channel state information (CSI) feedback procedure, a user equipment (UE) observing the CSI-reference signal (CSI-RS) resource configured by the serving base station with two ports configured over multiple sectors of the serving base station may select a precoder from the Type-II port selection codebook which accommodates additional subband amplitude information. The additional subband amplitude information may include a subband dynamic SFN activation indicator. In such a CSI report selected from the Type-II port selection codebook, the UE may indicate to the serving base station both a wideband SFN activation/deactivation and a subband SFN activation/deactivation in addition to the subband phase information. The serving base station may then use this CSI report to activate/deactivate SFN operations in both wideband and subband over each of the participating sectors.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that the UE has data to transmit. The user equipment may transmit, to a base station (BS) and based at least in part on determining that the UE has the data to transmit, a plurality of communications on a plurality of uplink beams to trigger the BS to perform beam measurements for the uplink beams. The user equipment may receive information that identifies a subset of the plurality of uplink beams to be used for an uplink data transmission based at least in part on transmitting the communications. The user equipment may transmit the uplink data transmission on the subset of the uplink beams based at least in part on receiving the information that identifies the subset of the uplink beams. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for group wake up signaling for millimeter wave relay node discovery. A method that may be performed by a base station (BS) includes communicating with a plurality of user equipments (UEs) in a cell, configuring a plurality of wake-up signals (WUSs) to transmit to different groups of UEs of the plurality of UEs in the cell, wherein configuring the plurality of WUSs is based, at least in part, on a relative location of each of the UEs in the different groups of UEs, and transmitting the plurality of WUSs to the different groups of UEs.

Abstract: Certain aspects of the present disclosure provide techniques for configuring beam failure recovery operations. A method includes performing beam failure detection of a beam pair link associated with a secondary cell, wherein a user equipment (UE) is configured with one or more uplink control channel groups, each of the one or more uplink control channel groups comprising a corresponding plurality of component carriers where one of the corresponding plurality of component carriers is designated for communication of an uplink control channel for the corresponding uplink control channel group; determining one or more cells on which to send a beam failure recovery request (BFRQ) message based on a number of uplink control channel groups the UE is configured with; sending the BFRQ on the one or more cells; and receiving a beam failure recovery response message on at least one of the one or more cells.

Abstract: Aspects of the disclosure relate to millimeter wave (mmWave) device discovery for relay communication using pseudo-omnidirectional beams. A first user equipment (UE) may transmit a synchronization signal over each pseudo-omnidirectional beam to enable a second UE to discover a presence of the second UE within a range of the first UE. Upon the occurrence of an external event, a base station may either trigger a beam training procedure with the second UE to establish a relay link between the first and second UEs or broadcast a message to all UEs requesting a relay link be established with the first UE. The first and second UEs may then select a directional beam pair link (BPL) for the relay link and establish the relay link to enable information to be relayed between the base station and the first UE via the relay link.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a first device and a second device may communicate over a communication link using a set of antenna elements. The first device may identify one or more antenna array reconfiguration trigger conditions and may correspondingly select a first subset of antenna elements for operation. The first device may transmit a message to the second device including an indication of the antenna array reconfiguration at the first device, a request for the second device to modify the second device's antenna array configuration, or both. The second device may receive the message and, based on the indication or the request, may modify its antenna array configuration. For example, the second device may select a second subset of antenna elements based on the selected first subset of antenna elements. The devices may communicate using their modified antenna array configurations.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive configuration information from a base station that indicates a set of resources for the UE to establish sidelink communications with another UE in a wireless network. The UE may transmit a first set of reference signals using a first set of beams to determine a set of neighboring candidate UEs for a sidelink connection. The UE may then transmit a second set of reference signals on a second set of beams to the neighboring candidate UEs, and may select a second UE located in the determined neighboring set using various beam scanning procedures. The UE may identify a transmit beam associated with the second UE, and may establish the sidelink connection using the identified transmit beam.
