Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, for a base station, a configuration message indicating a set of random access resources associated with monitoring by a relay node. The UE may transmit a random access message using the random access resources to the relay node and a timing advance associated with uplink data transmissions by the UE. The UE may then communicate with the base station via the relay node based on the random access message. In some examples, a UE may monitor for a relay reference signal from a relay node. The UE may determine a signal strength and a timing of the relay reference signal. The UE may determine whether an RSRP satisfies a threshold receive power, and may determine whether the timing of the relay reference signal is less than a timing threshold. The UE may transmit a downlink relay request to the base station to initiate relay communications.

Abstract: Support for multicast and broadcast data transmissions and acknowledgement feedback for the transmissions are being considered in 5G new radio (NR). Resource allocation techniques are provided to allocate uplink control channel resources for acknowledgement of downlink multicast/broadcast (MC/BC) data transmissions. An apparatus, such as a user equipment, receives a multicast/broadcast (MC/BC) configuration indicating a first physical uplink control channel (PUCCH) resource set for transmitting MC/BC acknowledgment (ACK)/negative acknowledgment (NACK), and a unicast configuration indicating a second PUCCH resource set for transmitting unicast ACK/NACK feedback. The apparatus also receives MC/BC data from a base station. The apparatus determines a first PUCCH resource from the first PUCCH resource set for transmitting MC/BC ACK/NACK feedback in response to the received MC/BC data and based on the received MC/BC configuration. The apparatus transmits the MC/BC ACK/NACK feedback to the base station in the determined first PUCCH resource.

Abstract: Support for hybrid automatic repeat request acknowledgment feedback for multiple multicast services in 5G new radio (NR) is provided. Resource allocation techniques are provided to allocate uplink control channel resource for acknowledgment of downlink multicast data transmissions associated with one or more multicast services. An apparatus, such a user equipment (UE), receives multicast data associated with one or more multicast services from a base station. The apparatus determines an uplink resource, such as a physical uplink control channel (PUCCH) resource, for transmitting multicast acknowledgement feedback, such as positive acknowledgement (ACK)/negative acknowledgement (NACK) feedback, in response to the received multicast data. The apparatus transmits the acknowledgement feedback for the one or more multicast services to the base station in the determined uplink resource.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a multicast service available for subscription by the UE or to which the UE is already subscribed. The UE may transmit a message, to a network node, that may include UE assistance information (UAI) indicating at least one of a UE capability to process multicast transmissions or a feedback scheme preference for reporting feedback for the multicast transmissions. The UAI may also include at least one of a multicast carrier preference, band or carrier measurement report, a multicast priority indication, or a measurement and reporting scheme preference for the multicast transmissions. The network node may receive the UAI and determine one or more parameters for multicast communications with the UE based on the UAI. The UE may receive the multicast transmissions from the network node in accordance with the UAI.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently facilitating acknowledgment (ACK) or negative acknowledgment (NACK) feedback from a user equipment (UE) for a set of transport blocks in one or more multicast transmissions from a base station. The UE may determine control channel resources for transmitting the ACK/NACK feedback, and each respective control channel resource may correspond to a distinct subset of the set of transport blocks. Once the UE determines a subset of transport blocks that the UE failed to decode (such as at least one transport block), the UE may determine a respective control channel resource that corresponds to the at least one transport block that the UE failed to decode. The UE may transmit ACK/NACK feedback on the respective control channel resource, which, in some examples, may indicate that the UE failed to decode the subset of transport blocks.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support synchronization signal block (SSB) configuration for narrow spectrum. In a first aspect, a method of wireless communication includes scanning one or more of a plurality of bandwidths to identify a synchronization bandwidth via which a SSB is wirelessly communicated. The plurality of bandwidths includes a first subset of bandwidths and a second subset of bandwidths. Reference frequencies of consecutive bandwidths of the first subset of bandwidths are separated by a first frequency step value and reference frequencies of consecutive bandwidths of the second subset of bandwidths are separated by a second frequency step value that is less than the first frequency step value. The method further includes receiving the SSB via the synchronization bandwidth. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station in a wireless communications system. The UE may perform a random access procedure to communicate with the base station. The base station may configure the UE with different sets of preamble parameters for different types of UEs. The UE may generate a random access preamble based on the sets of preamble parameters according to the type of the UE. The base station may indicate a location of the base station to the UE. The UE may identify a location of the UE. The UE may determine a pre-compensation timing based on a distance from the two locations. The UE and the base station may transmit subsequent communication according to the random access preamble, the pre-compensation timing, or any combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a network entity may pseudo-randomly generate frequency hopping indexes to support secure communication of sounding reference signals (SRSs). For example, the UE may securely obtain a key associated with communication a set of SRSs via respective portions of system bandwidth for communicating with the network entity. The UE and the network entity may generate a set of frequency hopping indexes using the key. The set of frequency hopping indexes may correspond to the set of SRSs, and each frequency hopping index may indicate a respective portion of the system bandwidth for communication of a corresponding SRS. The UE and the network entity may communicate the set of SRSs in accordance with the set of frequency hopping indexes.

Abstract: An apparatus may be configured to communicate at least one pilot signal with another apparatus according to a first configuration, at least one of a lower frequency density or a higher time density being indicated by the first configuration than a second configuration for a type of pilot signal that includes the at least one pilot signal. The apparatus may be further configured to communicate with the other apparatus based on the at least one pilot signal. Another apparatus may be configured to receive, from a base station, spatial relationship information or transmission configuration indicator (TCI) state information corresponding to a directional beam at the UE for communication on a channel. The apparatus may be further configured to apply the directional beam for communication with the base station on another channel in a sub-6 gigahertz (GHz) frequency band.
