Abstract: Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a base station, and a processor communicatively coupled to the transceiver. The processor is configured to receive a configuration message from the base station and determine a first set of antenna ports based on the configuration message. The processor is further configured to perform channel estimation on the first set of antenna port and perform or refrain from performing channel estimation on a second set of antenna ports based on the configuration message. The first set of antenna ports and the second set of antenna ports are in a code division multiplexing (CDM) group.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing mechanisms for reducing interferences for Sounding Reference Signal (SRS) by, for example, one or more of frequency domain interference randomization, code domain interference randomization, or power control. For example, a user equipment (UE) can be configured to determine a comb offset and/or a cyclic shift for each Sounding Reference Signal (SRS) transmission occasion for the UE. The comb offset and/or the cyclic shift change between different SRS transmission occasions of the UE. The UE is further configured to transmit an SRS to the base station using the determined comb offset and/or the determined cyclic shift during the SRS transmission occasion corresponding.

Abstract: Some embodiments include a system, apparatus, article of manufacture, method, and/or computer program product and/or combinations and sub-combinations thereof, for explicit power saving operations for a network-controlled repeater (NCR) in a wireless network. Some embodiments include an NCR that can receive a Downlink Control Information (DCI) format comprising an offset indication in a single Physical Downlink Control Channel (PDCCH) monitoring periodicity, KS, where KS is an integer of slots. The NCR can determine a single On-Off Pattern (OOP) within KS based at least on the offset indication, and communicate with a base station or a user equipment (UE) based at least on the determination. In some embodiments, an Off-State of the NCR is a default, and the offset indication identifies a duration of an On-State of the NCR beginning at a starting orthogonal frequency division multiplexing (OFDM) symbol of KS.

Abstract: A repeater configured to receive, on a side control channel from a component of a network, side control information including parameters at least for determining time domain resources on which to apply an indicated beam for uplink (UL) transmission reception or downlink (DL) transmission forwarding with a user equipment (UE) on an access link, determine, from the received parameters, whether to apply the indicated beam to a transmission (Tx) spatial filter, a reception (Rx) spatial filter, or both the Tx and Rx spatial filters and apply the indicated beam to the determined Tx spatial filter, Rx spatial filter, or both the Tx and Rx spatial filters for the determined time domain resources when forwarding the DL transmission to the UE or receiving the UL transmission from the UE for forwarding to the network.

Abstract: Some aspects relate to apparatuses and methods for a wireless system implementing mechanisms to transmit a measurement report using physical layer (L1) carrying a sounding reference signal (SRS) reference signal received power (SRS-RSRP) measurement to provide an indication of cross link interference (CLI) between a first user equipment (UE) and a second UE. The first UE can determine a channel state information (CSI) configuration received from the base station; and configure, based on the CSI configuration, a channel measurement resource (CMR) to include a SRS received from the second UE. The first UE can measure the SRS to obtain a SRS-RSRP measurement, generate a measurement report having the SRS-RSRP measurement, and transmit the measurement report to the base station using L1.

Abstract: Systems, methods, and apparatuses disclosed herein can generate and report a cross link interference (CLI) report. These systems, methods, and apparatuses can receive a CLI report configuration that outlines requirements for the CLI report, where the CLI report configuration is received on Layer 1 signaling, for example, Downlink Control Information (DCI) on a Physical Downlink Control Channel (PDCCH) or Layer 2 signaling, for example, downlink (DL) Media Access Control-Control Element (MAC-CE) on Physical Downlink Shared Channel (PDSCH). The CLI report configuration can identify the one or more CLI measurement resources to be measured and reported; one or more CLI measurements to be performed on the one or more CLI measurement resources; one or more CLI measurement occasions to measure the one or more CLI measurement resources; and one or more resources, to be used to report the CLI report. These systems, methods, and apparatuses can generate the CLI report as outlined in the CLI report configuration. Thereafter, these methods, and apparatuses can report the CLI report on Layer 1 signaling, for example, Uplink Control Information (UCI) on a Physical Uplink Control Channel (PUCCH) or Layer 2 signaling, for example, uplink (UL) Media Access Control-Control Element (MAC-CE) on Physical Uplink Shared Channel (PUSCH).

Abstract: This application relates to wireless communications, including methods and apparatus to manage uplink (UL) transmit switching with multiple timing advance groups (TAGs) for wireless devices. A wireless device is configured to use multiple carriers selected from a set of available carriers that can be associated with different TAGs. When a second set of carriers, used after switching from a first set of carriers, includes carriers that belong to different TAGs, the wireless device determines whether to transmit on one or more first uplink transmission occasions for each of the carriers in the second set of carriers based on whether a first UL transmission occasion for at least one carrier overlaps a switching gap time period. The wireless device can disallow transmission on first UL transmission occasions of one or more carriers to accommodate the overlap.

Abstract: This application relates to wireless communications, including methods and apparatus to manage uplink (UL) transmit switching with multiple timing advance groups (TAGs) for wireless devices. A wireless device is configured to select N≥2 radio frequency carriers for UL transmission from M>N available radio frequency carriers and subsequently send UL transmissions to a cellular wireless network based on the configuration. The M available radio frequency carriers are divided into distinct TAGs, each TAG having a distinct timing advance value, and the N radio frequency carriers belong to a single TAG. The wireless device is further configured to switch to a second set of N UL radio frequency carriers, after an uplink switching gap time period, based on a TAG medium access control (MAC) control element (CE), received the cellular wireless network, which specifies a second TAG from which to select the second set of N UL radio frequency carriers.
