Abstract: Antenna ports on wireless devices may be QCL. QCL antenna ports may be useful in improving channel statistics related to the antenna ports. UEs and base stations may be able to determine candidate QCL ports, transmit information identifying the candidate QCL ports, and receive feedback indicating whether the candidate QCL ports are QCL at the receiving device such as a UE or a base station.

Abstract: Various aspects of the disclosure relate to communicating uplink control information. As one example, a user equipment may send uplink control information to a base station. In some aspects, the number of symbols used to communicate the uplink control information may be based on a link gain associated with the UE and/or based on a payload size of the uplink control information. As another example, the user equipment may send channel information for a number of beams to the base station. In some aspects, the number of beams may be based on the type of channel that is used to send the uplink control information.

Abstract: In a mmW network, a UE and a base station may establish a link using a RACH procedure. Because mmW and other band communications may rely on accurate beamforming to overcome link attenuation, the UE may need to provide beam information feedback to the base station. In particular, the UE may receive a beam-formed message from the base station during the RACH procedure. The UE may determine beam information based on the received beam-formed message during the RACH procedure. The UE may transmit a message to the base station during the RACH procedure, and the message may include the determined beam information.

Abstract: A base station may transmit a quasi-collocation (QCL) relationship indication to a user equipment (UE) that indicates different QCL groups (e.g., QCL relationships corresponding to different port groups). The QCL relationship indication may include a tuple of transmission configuration indication (TCI)-states, TCI-states configured with TCI-state-sets, or multiple TCI-states indicated via an extended media access control (MAC) control element (CE). The QCL relationship indication may indicate a QCL relationship between one or more port groups of a first reference signal set and a plurality of port groups associated with a target reference signal. For example, the QCL relationship indication may indicate two QCL groups, where each QCL group includes a QCL relationship between a reference signal resource and a port group associated with a target reference signal. Using QCL group information, the UE may perform channel estimation for demodulating target reference signals, using the QCL antenna port group.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, base stations and user equipment (UEs) may use beamforming for transmitting random access channel (RACH) messages. A UE may transmit multiple RACH preamble messages (e.g., within a random access response (RAR) window) to initiate a RACH procedure. The UE may transmit the RACH preamble messages in transmission opportunities corresponding to reference signals received from the base station. In some cases, the UE may determine the number of RACH preamble messages to transmit within the RAR window based on an ability of the UE to simultaneously monitor for a RAR message in response to each of the transmitted messages. In other cases, the UE may transmit an indication of UE capabilities to the base station. The base station may determine a RACH resource configuration for the UE based on the capabilities and may indicate the configuration to the UE.

Abstract: Methods, systems, and devices are described for signaling protocols for proximity service functions in a wireless communication system. A first wireless device may identify a wireless relay requirement associated with the first wireless device. A proximity service protocol may be initiated between the first wireless device and a second wireless device based at least in part on the identified wireless relay requirement. The proximity service protocol may be initiated prior to an initiation of a communication data exchange between the first wireless device and the second wireless device. A relay link may be established, via the ProSe protocol, between the first wireless device and the second wireless device based at least in part on the identified wireless relay requirement.

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.

Abstract: Methods, systems, and devices for wireless communication are described that provide for synchronization signal (SS) blocks in which synchronization signals and broadcast channel transmissions may be transmitted. Broadcast channel transmissions may be demodulated using SS transmissions, reference signal transmissions, or combinations thereof. Broadcast channel transmissions may be transmitted in a subset of SS block time resources, and synchronization signals may be transmitted in another subset of SS block time resources. Reference signals may be transmitted using tones within the broadcast channel time resources, and may be transmitted at a higher density for portions of the broadcast channel transmission bandwidth that are outside of the SS transmission bandwidth. Waveforms for reference signal transmissions, and information provided by reference signal transmissions may be provided.

Abstract: Methods, systems, and devices are describe for signaling protocols for proximity service functions in a wireless communication system. A first wireless device may identify a group identity parameter associated with a multicast transmission of multimedia content. The first wireless device may map the identified group identity parameter to an identification parameter associated with at least one proximity service (ProSe) relay wireless device. The first wireless device may receive the multicast transmission of the multimedia content via the at least one ProSe relay wireless device based on the mapping of the identified group identity parameter to the identification parameter.

Abstract: A UE may receive a beam modification command that indicates a set of transmit beam indexes corresponding to a set of transmit beams of a base station, and each transmit beam index of the set of transmit beam indexes may indicate at least a transmit direction for transmitting a transmit beam by the base station. The UE may determine a set of receive beam indexes corresponding to receive beams of the UE based on the set of transmit beam indexes, and each receive beam index of the set of receive beam indexes may indicate at least a receive direction for receiving a receive beam by the UE. The UE may receive, from the base station, a signal through at least one receive beam corresponding to at least one receive beam index included in the set of receive beam indexes.
