Abstract: Various aspects described herein relate to techniques for beam discovery and beamforming in wireless communications (e.g., 5th Generation (5G) New Radio (NR)). In an aspect, a method related to signaling for channel state information reference signals (CSI-RSs) in wireless communications is provided. The method includes receiving, by a user equipment (UE), a CSI-RS beam of a set of CSI-RS beams, and the CSI-RS beam includes a change indication message. The method further includes determining, by the UE, whether the set of CSI-RS beams have changed based on a value of the change indication message.

Abstract: One apparatus may determine a first set of parameters associated with a first RACH procedure, the first set of parameters being associated with beam failure recovery for a first UE in a cell. The apparatus may send the first set of parameters to the first UE. Another apparatus may receive the first set of parameters associated with a first RACH procedure. The other apparatus may receive, from the first apparatus, a second set of parameters associated with a second RACH procedure. The other apparatus may generate a RACH preamble based on the first set of parameters or based on the second set of parameters. The other apparatus may send, to the first apparatus, the generated RACH preamble.

Abstract: Certain aspects of the present disclosure provide techniques for random access channel (RACH) communication. For example, certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes transmitting a first message comprising a RACH preamble, receiving a second message comprising random access response (RAR) in response to the RACH preamble, transmitting a third message in response to the RAR, receiving a fourth message (MSG4) comprising a contention resolution message in response to the third message. In certain aspects, the fourth message may include a timing advance (TA) parameter which may be used to communicate one or more messages.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless node may establish a wireless connection between the wireless node and a second wireless node in a wireless backhaul communications network. The wireless node may identify a first set of common resources for use in at least one of access communications or backhaul communications. The first set of common resources is allocated for common use by the wireless nodes of the wireless backhaul communications network. The wireless node may identify a second set of partitioned resources available for at least one of access communications or backhaul communications. The second set partitioned into a plurality of subsets each allocated for use by selected subsets of one or more of the wireless nodes of the wireless backhaul communications network.

Abstract: Systems, methods, and apparatuses for performing a beam recovery procedure using a second CC are disclosed. A UE may perform a beam recovery procedure using two component carriers (CCs): for example, CC1 may be a beam formed millimeter wave (MMW) carrier having a beam recovery procedure and CC2 may be an assisting carrier such as a sub-6 GHz carrier. In a first example, a UE may trigger beam recovery for CC1 (on CC2), generate a beam measurement report, and transmit the beam report on resources allocated for uplink transmission on CC2. In a second example, a new scheduling request (SR) may be defined on CC1 for CC2 beam recovery. In a third example, RACH resources or procedures on CC2 may be used to perform the beam recovery for CC1.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a discovery signal transmitted from a connection point (CP) via a directional beam. The discovery signal may include first information (including beam sweep configuration information) related to the CP. The apparatus then transmits an association signal to the CP based on the beam sweep configuration information and monitors for a resource grant from the CP based on the transmitted association signal. Alternatively, the apparatus transmits a discovery signal via a directional beam to a user equipment (UE). The discovery signal may include first information (including beam sweep configuration information) related to the apparatus. The apparatus then receives an association signal from the UE based on the beam sweep configuration information and determines a resource grant for communicating with the UE based on the received association signal.

Abstract: Wireless communications systems and methods related to allocating resource blocks and resource block groups in a system band in order to reduce overhead associated with resource allocation. To reduce overhead, the wireless communication device communicates a signal in a control channel that indicates a general area and a resource block in the general area that stores data. The wireless communication device then communicates multiple resource blocks that include the resource block and communicates the data in the resource block using the signal. To reduce overhead, the wireless communication device also communicates multiple mappings for each resource block group into a set of resource blocks and a signal in a control channel that selects one of the multiple mappings. The communication device then determines resource blocks that are included in the resource block group according to the mapping, and communicates data in these resource blocks.

Abstract: Methods, systems, and devices for wireless communication are described that provide for transmitting different sets of control messages through a relay to a central unit (CU) and a core network of a wireless communications system. The different sets of control messages may include a first set of control messages for an access radio link between the relay and the CU and a second set of control messages for a fronthaul radio link between the relay and the CU. Techniques may include multiplexing of messages on a radio bearer (RB), establishment of separate RBs for different control messages, and encapsulation of one type of control message for transmission with the other type of control message.

Abstract: A user equipment (UE) can transmit a beam failure recovery request using contention-based physical random access channel (PRACH) resources to supplement and/or replace non-contention-based resources for transmitting the beam failure recovery request. The UE can reduce beam recovery latency by informing its intention for beam failure recovery by transmitting a beam failure recovery request during the random access channel (RACH) procedure. The base station may dedicate a set of RACH resources that can be used for both transmitting regular contention-based RACH messages and beam failure recovery request.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for determining to not transmit a portion of a second signal that overlaps in time with a first signal. A user equipment (UE) may identify a first signal to be communicated during a first time duration using a first beam pair link (BPL) and identify a second signal that is scheduled to be communicated during a second time duration using a second BPL. The UE may identify a misalignment between timing advance values for the BPLs, the misalignment causing an overlap in time between the first signal scheduled during the first time duration and the second signal scheduled during the second time duration. The UE may determine whether to drop part of the second signal and communicate the first signal and a remaining portion of the second signal based at least in part on the determining.
