Abstract: Methods, systems, and devices for wireless communications are described. For example, described techniques provide for performing multipath fading equalization at a reconfigurable intelligent surface (RIS), allowing a receiving device to omit an equalization procedure or to perform a simpler equalization. A transmitting device, such as a network entity, may select a RIS that is within a sufficient proximity to a receiving device, such as a user equipment (UE), that multipath fading of the RIS to receiver wireless link is likely to be below a threshold. The network entity may configure the selected RIS with a phase matrix to perform over-the-air equalization to compensate for multipath fading over the network entity to RIS wireless link. The UE may omit an equalization procedure or may perform a simpler equalization procedure as compared to a scenario where the RIS does not compensate for multipath fading.

Abstract: Systems and methods establishing and maintain a direct User Equipment to User Equipment communication link are disclosed. A User Equipment (UE) may receive a Sounding Reference Signal (SRS) from a neighboring UE. The UE may determine from the SRS that the UE is a good candidate for a direct link. The UE may also determine from the SRS an ID associated with the neighboring UE. The UE may send a direct link request to the UE serving gNB. The serving gNB may forward the request to a gNB serving the neighboring UE. The gNBs may negotiate a joint schedule for a beam a UE to UE beam search. The beam search may be conducted using SRS resources. The results of the beam search may be sent to the gNB and the gNB may determine a beam pair for a direct link.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a mapping between a set of synchronization signal block resources and a set of operating frequencies within a frequency band. The UE may identify a parameter of a synchronization signal block based on an operating frequency of the set of operating frequencies for conveying the synchronization signal block and a direction of a beam for conveying the synchronization signal block. The parameter may include an index of the synchronization signal block. The UE may monitor for the synchronization signal block based on the identified parameter.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration message indicating that a control resource set for a downlink control channel is associated with a plurality of demodulation reference signal (DMRS) ports. The UE may determine, based at least in part on the configuration message, that a first set of DMRS resource elements in a first symbol of the control resource set correspond to a first DMRS port of the plurality of DMRS ports and a second set of DMRS resource elements in a second symbol of the control resource set correspond to a second DMRS port of the plurality of DMRS ports. The UE may decode the downlink control channel based at least in part on the determining.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a first UE may receive an indication of first resources from a second UE. In some examples, the second UE may be a UE configured to receive a transmission from a third UE over the first resources. In some such examples, the first UE may transmit, to a fourth UE, a sidelink transmission over available resources that exclude the first resources. Additionally, or alternatively, the second UE may be a UE that received sidelink control information from the third UE indicating the resources for transmission by the third UE to a fourth UE. In some such examples, the first UE may transmit, to the second UE, a sidelink transmission over available resources that exclude the first resources.

Abstract: A user equipment (UE) may receive, from at least one of a base station or a configuring UE, a configuration of a plurality of sidelink power control parameter sets, a media access control (MAC) control element (CE) (MAC-CE) activating transmission configuration indicator (TCI) states and indicating sidelink power control parameter sets, and control information indicating a TCI state and a sidelink power control parameter set. The UE may transmit the sidelink communication in a direction based on the TCI state and with a transmission power indicated in the control information. The MAC-CE may include a joint MAC-CE or separate MAC-CEs to update or configuration of the sidelink TCI and the power control parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine, during a multi-slot downlink transmission, that a mapping from a transmission configuration information (TCI) state index to a first TCI state configuration has changed to a second TCI state configuration. The UE may select, based at least in part on the determined change, the first TCI state configuration or the second TCI state configuration to use for at least a portion of the multi-slot downlink transmission. The UE may receive the multi-slot downlink transmission during one or more slots according to the selected TCI state configuration and the TCI state index.

Abstract: Methods, systems, and devices for wireless communications are described. A first device, which may be a user equipment (UE), may perform a measurement on a wideband channel in a millimeter wave (mmW) frequency band. The wideband channel may include a set of subbands that span the wideband channel. Based on the measurement, the first device may determine a set of power control parameters for the wideband channel. The first device may determine to transmit a signal using a subband of the set of subbands and may modify one or more power control parameters of the set of power control parameters based on a power offset for the subband. The first device may transmit an indication of the modified one or more power control parameters to a second device. The first device may transmit the signal to the second device based on the modified one or more power control parameters.
