Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify a multi-link aggregation capability (e.g., a capability to transmit in parallel over multiple wireless links), and may transmit an indication of such capability to another wireless device. The indication may be included in an information element (e.g., a multi-band element) of a transmission frame. For example, the indication may be included in a multi-band element of a beacon, of association signaling, of probe signaling, of an add block acknowledgement (ADDBA) request, etc. The indication sent over one of the wireless links may include information for some or all the multiple links supported for multi-link aggregation. This information may include media access control (MAC) address, channel information, operating class, security information, etc. for each link. Such multi-link aggregation information may be used, for example, for establishment of improved block acknowledgment (BA) sessions between wireless devices.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein may provide power control configuration parameters using MAC-CE messaging. A base station may transmit a MAC-CE message that includes a power control configuration identifier. The UE may identify a power control configuration according to the power control configuration identifier. The power control configuration may include one or more power control parameters and a path loss reference signal identifier. The UE may update the path loss reference signal for an uplink transmission based on the received MAC-CE message and adjust power for performance of the uplink transmission according to one or more measurements of the updated path loss reference signal.

Abstract: The present disclosure provides for identifying, based on downlink control information (DCI), a physical uplink shared channel (PUSCH) transmission associated with a network entity, determining that a dedicated physical uplink control channel (PUCCH) resource is not configured for uplink transmission to the network entity, determining a default spatial relation reference signal for the PUSCH transmission based on determining that the PUCCH resource is not configured, and performing the PUSCH transmission based on the default spatial relation reference signal.

Abstract: Various aspects of the disclosure relate to distributed multiple-input multiple-output (MIMO) communication such as coordinated beamforming or Joint MIMO. In some aspects, distributed MIMO is used to support communication in a cluster of wireless nodes (e.g., access points). A distributed MIMO scheduling scheme as taught herein is used to schedule the wireless nodes (e.g., access points and/or stations) operating within the cluster. For example, stations may be scheduled across basis services sets of the access points for a downlink transmission and/or an uplink transmission.

Abstract: Methods, systems, and devices for wireless communications are described. Interference between random access channel (RACH) transmissions and Industrial Internet of Things (IIoT) transmissions may be avoided with a RACH occasion forbidden mask and a dynamic indication of availability of downlink retransmission resources. A user equipment (UE) may receive an indication of a RACH configuration and a forbidden mask associated with the RACH configuration. The UE may identify, from a set of random access occasions indicated by the RACH configuration, a subset of allowed random access occasions based on the forbidden mask. The UE may transmit a random access message during at least one allowed random access occasion of the subset. Additionally or alternatively, a base station may determine whether one or more transmissions on a component carrier (CC) were successful, and transmit downlink control information (DCI) indicating whether a set of random access occasions are available on the CC.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling configuring the UE with a set of frequency resources and a semi-persistent resource allocation indicating a semi-persistent resource occasion on each frequency resource of the set. The UE may monitor semi-persistent resource occasions on each of the set of frequency resources for a copy of a data transmission. If the UE receives and decodes the data transmission from at least one of the semi-persistent resource occasions, the UE may transmit an acknowledgement message on a frequency resource of the set. Additionally, the UE may refrain from transmitting a feedback message on the other frequency resources of the set. If the UE does not receive and successfully decode the data transmission from any of the semi-persistent resource occasions, the UE may transmit a negative acknowledgement message on one of the set of frequency resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, via a first carrier, an indication of an offset for scheduling a reference signal on a second carrier, wherein the offset indicates a duration between downlink control information (DCI), that schedules the reference signal, and the reference signal; determine a first numerology of the first carrier and a second numerology of the second carrier; and determine a time offset for the reference signal based at least in part on the offset and at least one of the first numerology, the second numerology, or both the first numerology and the second numerology. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described in which spatial relations for one or more uplink reference signal transmissions, such as sounding reference signal (SRS) transmissions, may be configured and a particular spatial relation indicated in a medium access control (MAC) control element (CE). A base station may configure a pool of available spatial relations for use in SRS transmissions, and the MAC-CE may indicate which spatial relation of the set of available spatial relations is to be used. In other cases, the MAC-CE may provide all of the spatial relation information for an associated SRS transmission. The UE, responsive to receiving the MAC-CE, may transmit a SRS to the base station using the indicated spatial relation.
