    Abstract: A method of beam failure recovery for multi-beam operation in wireless communication systems with beamforming is proposed. Specifically, a four-step beam failure recovery procedure is proposed. In a first step of beam failure detection, UE detects a beam failure condition of the original serving beam pair link. In a second step of new candidate beam identification, UE performs measurements for candidate beam selection. In a third step of beam failure recovery request (BFRQ) transmission, UE transmits a BFRQ message to BS upon the triggering condition for BFRQ transmission is satisfied. In a fourth step of monitoring BS response, UE monitors BS response to decide the success or failure of the beam failure recovery.

    Abstract: Techniques and examples of interlace design for New Radio unlicensed spectrum (NR-U) operation are described. An apparatus (e.g., user equipment (UE)) assigns a plurality of resources to a plurality of interlaces such that, when the plurality of resources cannot be evenly distributed among all the plurality of interlaces, one or more remaining resources of the plurality of resources are assigned to one or more interlaces of the plurality of interlaces. The apparatus then performs an uplink (UL) transmission to a wireless network in a New Radio unlicensed spectrum (NR-U) using the plurality of resources with block interlaced frequency-division multiple access (B-IFDMA).

    Abstract: A method of control signaling in a beamforming system is proposed. A user equipment (UE) receives control beam transmission from a base station using a set of control beams in a beamforming network. Each control beam comprises a set of DL control resource blocks, a set of UL control resource blocks, and an associated set of beamforming weights. The UE selects a control beam for establishing a connection with the base station. The UE then performs random access with the base station using the selected control beam.

    Abstract: Aspects of the disclosure provide a method for beam management at a base station (BS) in a wireless communication system. The method can include transmitting a beam training reference signal (RS) resource configuration from a base station (BS) to a user equipment (UE) in a wireless communication system, transmitting an anchor association index indicating an association between a beam pair link and a set of second transmit beams of the BS, wherein the beam pair link is formed by a first transmit beam of the BS and a receive beam of the transmitting beam training RSs according to the beam training RS resource configuration on the set of second transmit beams, and receiving a measurement report including quality measurements of beamformed channels over the receive beam and a subset of the second transmit beams.

    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE determines that up-link control information for channel state information (CSI) acquisition and up-link control information for beam management is to be transmitted on a same up-link channel. The UE includes the up-link control information for beam management in at least one CSI-acquisition report for reporting the up-link control information for CSI acquisition. The UE sends the at least one CSI-acquisition report to the base station on the up-link channel.

    Abstract: A method of configuring and applying UE beam training gaps for simultaneous UE beam training and data reception in a beamforming wireless communication system is proposed. UE beam training gaps are configured by the base station for each UE. Typically, UE-specific data transmission can take place during the serving control beam time region. The UE beam training gaps are periods where UE-specific data transmission does not happen within the serving control beam time region. During each UE beam training gap, non-serving UE beam training can take place, where the UE performs intra-frequency reference signal measurements from serving and/or neighbor cells using various non-serving UE beams. The UE beam training gaps are configured and signaled to each UE, and each individual UE can have different data occupancy region within its serving CB time region.
