Abstract: Aspects herein relate to wireless devices, circuits, and methods for determining a PRACH resource mapping comprising a starting symbol position within a reference slot, wherein the starting symbol position is determined based, at least in part, on a subcarrier spacing configuration of PRACH resources of a wireless network that a wireless device is operating on; and using the radio to transmit a RACH preamble and an associated RA-RNTI via the determined PRACH resource mapping. Further aspects herein relate to devices, circuits, and methods for using a modified RA-RNTI for transmission or reception of data over a wireless network, wherein the wireless network has a subcarrier spacing configuration of PRACH resources, wherein a size of the subcarrier spacing configuration of the PRACH resources causes out-of-range RA-RNTI values to be calculated using a legacy RA-RNTI equation in an unmodified form, wherein the range of permissible RA-RNTI values is from 0 to 216−1.

Abstract: The present disclosure relates to devices, apparatuses, and methods for enhanced PHR reporting in support of UE antenna scaling. A wireless device, which comprises at least one antenna array each comprising a plurality of antenna elements may perform antenna scaling by activating or deactivating at least one of the plurality of antenna elements (with corresponding RF chains) of one or more antenna arrays. The wireless device may generate a power headroom (PHR) report based at least on a difference between beamforming gains obtained after the antenna scaling and before the antenna scaling. The wireless device may then send the PHR report to a base station in communication with the wireless device.

Abstract: A user equipment (UE) is configured to establish a connection to a base station, wherein the base station configures the UE with a first beam corresponding to a first transmission reception point (TRP) and a second beam corresponding to a second TRP, wherein the first and second beam are in frequency range 2 (FR2) and wherein the UE does not support simultaneous reception of multiple beams in FR2, detect a beam failure during a beam failure detection (BFD) evaluation period, identify one or more candidate beams during a candidate beam detection (CBD) evaluation period and transmit a beam failure recovery (BFR) request to the base station.

Abstract: Apparatuses, systems, and methods for SRS collision handling. A wireless device may determine whether simultaneous transmission of at least two sounding reference signals (SRSs) is allowed; if it is determined that the simultaneous transmission of the at least two SRSs is allowed, transmit the at least two SRSs simultaneously; and if it is determined that the simultaneous transmission of the at least two SRSs is not allowed, transmit one SRS of the at least two SRSs, and drop the other SRS of the at least two SRSs.

Abstract: Beam determination refers to a set of procedures for an access node (AN) and a user equipment (UE) to select from among downlink communication beams and/or uplink communication beams for downlink and/or uplink communications, respectively. Often times, the downlink communication beams can include one or more downlink control channels, for example, a Physical Downlink Control Channel (PDCCH) and/or a Physical Downlink Shared Channel (PDSCH), to provide downlink reference signals, such as channel-state information reference signals (CSI-RSs), to the UE. The AN can execute various exemplary downlink beam scheduling procedures to control the transmission of the downlink reference signals, such as the CSI-RSs to provide an example, over the downlink communication beams. In some embodiments, the UE can utilize the CSI-RSs to perform beamforming failure detection (BFD) and beamforming failure recovery (BFR) in the wireless networks.

Abstract: This disclosure relates to techniques for performing wireless communications including signaling resource allocation for multiple transport blocks (TBs) on either PUSCH or PDSCH using a single control element, such as a DCI. In various scenarios, the multiple TBs may be scheduled either at contiguous or at non-contiguous dime-domain resources. Various mechanisms are disclosed for performing signaling the resource allocation for the multiple TBs without introducing excessive signaling overhead.
