    Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for radio link monitoring for multiple DCI based transmissions. The UE may receive, from a network node, a configuration for multiple downlink control information (DCI) mode operation in which a physical downlink shared channel (PDSCH) is scheduled by multiple DCIs from a number of control resource sets (CORESETs). The number of CORESETs may exceed a number of CORESETs the UE can monitorable. The UE may determine a set of CORESETs to monitor based, at least in part, on one or more CORESET properties. The set of CORESETs to monitor may be less than the number of CORESETs. Additionally, the UE may monitor the set of CORESETs for at least one of a radio link failure or a beam failure.

    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: To reduce the beam reporting latency, a base station may include a sounding reference signal (SRS) indication to a wireless communication device (UE) as part of the transmission configuration information (TCI) transmitted to the UE, allowing the UE to receive a corresponding downlink signal using the same beam (or with the same beam) the UE used to transmit (or with which the UE transmitted) the SRS indicated in the TCI. The SRS may be one of multiple SRSs previously transmitted by the UE. The UE may transmit the multiple SRSs periodically and/or according to semi-persistent scheduling, or it may transmit them aperiodically. Therefore, the UE does not need to report the beam quality, and the base station may perform the necessary beam measurement(s) instead. Various parameters and conditions may be defined for the UE to support SRS-based TCI.

    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.
