Abstract: Methods, systems, and devices for wireless communication are described. Some examples provide for identifying a primary synchronization signal (PSS) sequence of a synchronization subframe, determining, for the synchronization subframe, an extended synchronization signal (ESS) sequence based at least in part on the PSS sequence and transmitting the synchronization subframe. Other examples provide for generating an ESS sequence for a synchronization subframe to be communicated to a UE, scrambling the ESS sequence based at least in part on cell-specific information associated with the base station and transmitting, to the UE, the scrambled ESS sequence in the synchronization subframe.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify resources associated with a beamformed signal, the identified resources being used by a user equipment (UE) for channel measurements of the beamformed signal, the beamformed signal being one of a plurality of beamformed signals. The base station may generate a signal indicating at least a portion of the identified resources and transmit the signal to the UE. The UE may receive the signal and perform a channel measurement of the beamformed signal using the indicated resources. The UE may transmit, to the base station, a measurement report comprising the channel measurement associated with the beamformed signal.

Abstract: In wireless communication systems that support 5th generation wireless systems (5G) or New Radio (NR) protocols, subframes used for communication may have different numerology options. Numerology options may refer to the characteristics of the subframe such as a tone spacing within each symbol of the subframe, a symbol duration for each symbol of the subframe, a number of symbols in the subframe, etc. A subframe may include a control channel (e.g., the Physical Downlink Control Channel (PDCCH)) and a data channel (e.g., the Physical Downlink Shared Channel (PDSCH)). In an aspect, the control channel and the data channel within the subframe may have different numerologies. As such, a need exists to signal the numerology of the subframe to users and to determine whether and how to multiplex the control channel and the data channel into the subframe.

Abstract: A UE may receive a directional synchronization subframe from a base station and transmit a scheduling request to the base station during a time period based on the directional synchronization subframe. The scheduling request may enable a base station to grant the UE resources to send a buffer status report (BSR). The time period may be associated with a random access channel (RACH) time period. The UE may also transmit a scheduling request within a frequency region of the RACH time period. The scheduling request may be transmitted based on a received indication of a set of subcarrier, a cyclic shift, or a sequence index. In some examples, the resources used by the UE to send the BSR may include physical uplink shared channel (PUSCH) or physical uplink control channel (PUCCH) resources.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless systems, a base station may configure a user equipment (UE) for random access (RACH) message transmission in dedicated RACH resources during, for example, a handover process. The contention-free random access (CFRA) resources may allow the UE to transmit RACH messages at a higher transmission power than contention-based random access (CBRA) resources. The base station may indicate, to the UE, RACH transmission parameters for CFRA that are different than parameters for CBRA. These parameters may include configuration information, frequency division multiplexing information, RACH retransmission parameters, target received power, response window length, etc. The UE may use the indicated RACH transmission parameters to transmit a RACH message to the base station. The base station may respond with a RACH response message, and the base station and UE may synchronize upon completion of the RACH procedure.

Abstract: Methods, systems, and devices for wireless communication are described that provide for establishment of communication links between nodes in a wireless network, in which an access node (e.g., a node that provides access to a core network) may provide a communication link configuration and resources for communications between multiple nodes. In some cases, an access node may receive a request from a first node to establish a communication link with a second node. The communication link may be, for example, a directional transmission beam that carries data or control information, or a combination thereof, between the first node and the second node. The access node may determine the communication link configuration based on one or more link measurements provided by the first node or second node, and provide the configuration information to one or both of the first node or the second node.

Abstract: A wireless node (e.g., a slave relay node) may receive scheduling commands over multiple wireless links and identify a scheduling conflict. For example, the wireless node my identify a conflict of wireless resources indicated by the received scheduling commands. The wireless node may select a non-conflicting subset of the scheduling commands based on a conflict policy, and transmit data over the wireless links according to the non-conflicting subset of the scheduling commands. Additionally or alternatively, the wireless node may transmit a conflict report indicating the identified scheduling conflict. The conflict report may be sent to other wireless nodes (e.g., master relay nodes associated with the conflicting scheduling commands). The other wireless nodes may engage in negotiation signaling to resolve the scheduling conflict, and may transmit an updated scheduling command to the slave relay node. The slave relay node may transmit data over wireless links based on the updated scheduling command.

Abstract: Methods, systems, and devices for wireless communication are described. A first wireless node may establish a wireless connection between the first wireless node and a second wireless node in a wireless backhaul communications network. The first wireless node may identify, at the first wireless node, a need for additional resources for wireless communications with a third wireless node. The first wireless node may transmit a request message to the second wireless node indicating that resources are requested at the first wireless node. The first wireless node may receive an indication of one or more available resources from the second wireless node. The first wireless node may select one or more of the available resources for wireless communications with the third wireless node.

Abstract: Methods, systems, and devices for wireless communication are described. Signaling of a radio frequency (RF) band associated with a synchronization signal (SS) block detected by a user equipment (UE) may be transmitted to a base station. For example, a base station may transmit a set of SS blocks to multiple UEs, where the SS blocks are frequency division multiplexed such that each SS block is transmitted in a respective RF band. A UE may receive one or more of the transmitted SS blocks and determine a preferred SS block from the received SS blocks. The UE may in turn transmit an message to the base station that indicates the RF band of the preferred SS block. In some cases, the base station may optionally transmit a request to the UE to transmit the indication of the RF band.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first synchronization signal (SS) block that does not include remaining minimum system information (RMSI). The first SS block may indicate an offset for obtaining a second SS block that includes RMSI. The UE may determine a location of the second SS block based at least in part on the offset. Numerous other aspects are provided.
