Abstract: A wireless network may include a base station and user equipment (UE). The UE may transmit uplink (UL) signals to the base station using a dynamically adjustable maximum UL duty cycle. When the UE identifies that a user is in proximity to the UE, the UE may transmit an indicator to the base station. The indicator may identify that a radio-frequency exposure (RFE) event has occurred and/or a suggested maximum UL duty cycle that would allow the UE to satisfy limits on RFE. The base station may limit a UL grant to the UE so that the UE performs subsequent communications using the suggested maximum UL duty cycle or a different maximum UL duty cycle. Coordinating adjustment of UL duty cycle in this way may allow the UE to meet limits on RFE without requiring the UE to perform maximum transmit power level reductions.

Abstract: An apparatus configured to be employed in a user equipment (UE) associated with a new radio (NR) system is disclosed. The apparatus comprises one or more processors configured to select a first resource from a candidate resource set comprising a plurality of candidate resources within a first resource selection window. In some embodiments, the first resource is to be utilized by the UE for a first transmission of a transport block (TB) over sidelink. In some embodiments, a size of the first resource selection window is derived based on a (pre)configured maximum number of retransmissions of the TB. In some embodiments, the one or more processors is further configured to generate a first transmission signal comprising the first transmission of the TB, to be transmitted over the sidelink using the selected first resource.

Abstract: A method and apparatus of a device that determines a physical downlink shared channel scheduling resource for a user equipment device and a base station is described. In an exemplary embodiment, the device selects a plurality of component carriers from a pool of available component carriers associated with a wireless link established between the user equipment device and the base station. In addition, the device selects a virtual component carrier from the plurality of component carriers.

Abstract: This disclosure relates to techniques for scheduling multiple downlink transmissions using a single downlink control transmission in a wireless communication system. A wireless device may determine a beam configuration for use for receiving multiple downlink transport blocks scheduled by a single downlink control transmission. In some instances, the wireless device may be configured to skip one or more control channel monitoring occasions that overlap with the downlink transport blocks. The wireless device may provide hybrid automatic repeat request feedback for the downlink transport blocks.

Abstract: This disclosure relates to techniques for performing wireless communications including schedules for multiple communications between a user equipment device (UE) and a base station. Techniques for updating such schedules are disclosed. The update may be explicitly signaled or may be determined implicitly. The UE and the base station may perform communications according to the updated schedule.

Abstract: Systems and methods are provided for determining which part or operation of one or more Secondary Cell (SCell) activation process (es) to defer or restart when an attempt to simultaneously perform multiple operations of the one or more SCell activation processes would cause interference. For example, radio frequency (RF) tuning and/or automatic gain control (AGC) settling for an SCell activation may be deferred until after a Hybrid Automatic Repeat Request (HARQ) for the SCell activation is sent by a UE to the SCell. In another example, RF tuning and/or AGC settling corresponding to the activation of a first SCell may be deferred until after RF tuning and/or AGC settling corresponding to the activation of a second SCell is complete.

Abstract: A base station (BS) may receive a plurality of repetitions of a Physical Uplink Control Channel (PUCCH) from a user equipment (UE), and accumulate the received repetitions to obtain a resultant signal. The ability to accumulate repetitions enables the base station to experience a higher probability of successful recovery of the PUCCH payload bits than if decoding were based on the reception of a non-repeated transmission of the PUCCH. The base station may configure the number of repetitions, the temporal gap between the repetitions, and mode of repetition of the PUCCH. In an intra-slot mode, more than one copy may be received from each configured slot, with or without frequency hopping. In an inter-slot mode, one copy is received per configured slot. Different repetitions may be transmitted by the UE in different directions, according to a spatial consistency pattern.

Abstract: Technology is provided for supporting different numerologies for concurrent intra-frequency measurements and downlink data reception. A user equipment (UE) may send a message to the a wireless network to indicate whether the UE supports a mixed numerology wherein a different subcarrier spacing (SCS) is used in a serving cell or a neighboring cell for concurrent processing of at least two of: intra-frequency measurement by the UE of a synchronization signal block (SSB); intra-frequency measurement by the UE of a channel state information reference signal (CSI-RS) for mobility; and reception by the UE of a physical downlink control channel (PDCCH) or a physical downlink shared channel (PDSCH). Based on the indication, the network may configure at least one of a CSI-RS measurement expectation, an SSB measurement expectation, and a scheduling restriction for reception of the PDCCH or the PDSCH by the UE.

Abstract: A user equipment (UE) configured to transmit a scheduling request (SR) to a second UE which causes the second UE to determine a set of sidelink transmission resources for use by the UE. The UE may then receive information regarding a determined set of sidelink transmission resources from the second UE and then transmit sidelink communications using at least a subset of the determined set of sidelink transmission resources. The determined set of sidelink transmission resources may be recommended and reserved or non-reserved resources. The UE may transmit configuration information concerning transmission resources to the second UE to be used in transmitting, the SR. The second UE may monitor the channel for arrival of the resources. The SR may be encoded as a cyclic shift of the SR corresponding to an ACK-only sequence, an ACK/NACK sequence, or a certain sequence of the SR based on a configuration index.
