    Abstract: Apparatuses, systems, and methods for a wireless device to disable a HARQ feedback in either a semi-static way or in a dynamic way and to perform HARQ optimization. The wireless device may be configured to receive a first set and a second set of HARQ process numbers, where the first set and the second set of HARQ process numbers correspond to a first set and a second set of HARQ processes respectively, where each HARQ process in the first set of HARQ processes is configured to enable a HARQ feedback, and where each HARQ process in the second set of HARQ processes is configured to disable or enable a HARQ feedback. The wireless device may be configured to receive a grant configuration or a SPS, where the grant configuration or the SPS include a flag indicating whether a HARQ-based retransmission is disabled.

    Abstract: A base station may be configured to perform operations related to link management for a remote user equipment (UE). The operations comprising, transmitting configuration information to the remote UE and receiving information corresponding to a serving link associated with the remote UE. The operations further comprising determining that the serving link associated with the remote UE is to be switched from a first communication link to a second communication link. The operations further comprising, transmitting a message to the remote UE indicating that the serving link associated with the remote UE is to be switched from the first communication link to the second communication link. The operations further comprising, transmitting a message to a relay UE. The message is configured to trigger the relay UE to perform an operation corresponding to the serving link associated with the remote UE.

    Abstract: Some embodiments include a system, method, and computer program product for managing beam switching at a higher subcarrier spacing (SCS) at millimeter wavelength (mmWave) frequencies in a 5G wireless communications system. A user equipment (UE) transmits a beam switching gap (BSG) capability to a 5G Node B (gNB). The UE receives a transmission configuration indicator (TCI) state from the gNB, and performs a beam switch to the TCI state corresponding to a first beam. The UE can receive a first control resource set (CORESET) on the first beam and a second CORESET on a second beam where the BSG occurs between the first CORESET and a second CORESET. The UE can perform beam switching within the BSG from the first beam to a second beam, and receive the second CORESET on the second beam. The UE can determine and transmit modified candidate values of beam switching parameters to the gNB.

    Abstract: A user equipment (UE) is configured to use multiple beams for transmission or reception. The UE receives, from a base station, at least one medium access control (MAC) control element (CE) that indicates multiple activated transmission configuration indicator (TCI) states, receives, from the base station, at least one downlink control information (DCI) indicating a subset of TCI states of the multiple activated TCI states, wherein the MAC CE and the DCI are part of a TCI configuration, and wherein the subset of TCI states corresponds to multiple transmission and reception points (TRPs) of a wireless network, maps the subset of TCI states to the corresponding multiple TRPs based on the TCI configuration and selects a beam used for transmission or reception based on one mapped TCI state of the mapped subset of TCI states.

    Abstract: Methods and apparatus for Timing Advance (TA) validation are disclosed. In some embodiments, a method for wireless communication at a user equipment (UE) comprises receiving, from a base station, configuration information, where the configuration information specifying a configured grant (CG)-small data transfer (SDT) resource available for use by the UE and specifying a configuration for a Reference Signal Received Power (RSRP) change-based TA validation method to be met in order to perform a SDT while in the RRC inactive state, the RSRP change-based TA validation method having configured TA validation criteria that is evaluated based on two measurement windows for timing advance (TA) validation, and at least one boundary of at least one of the two measurement windows for TA validation is based on a minimum of either a Frequency Range 2 (FR2) measurement period and a scaled Discontinuous Reception (DRX) cycle period, existing at time of TA validation criteria evaluation.
