Abstract: Apparatuses, systems, and methods for radio resource management (RRM) signal reception. A user equipment device (UE) may receive, via a first reception path, an RRM related signal and receive, via a second reception path, a non-RRM related signal that may be multiplexed with the RRM related signal onto a symbol. The first reception path may be a first antenna port of an antenna panel or a first antenna panel of the UE and the second reception path may be a second antenna port of the antenna panel or a second antenna panel of the UE. The RRM related signal may include a reference signal for RRM. and may be included in a non-zero power (NZP) interference measurement.

Abstract: A cellular base station (BS) which determines an aperiodic sounding reference signal (SRS) triggering offset configuration specifying an offset between an aperiodic SRS trigger received by a user equipment (UE) and transmission of the SRS by the UE. The cellular base station may determine that the SRS triggering offset should be adjusted. In response, the cellular base station may transmit signaling to the UE specifying a new value for the aperiodic SRS triggering offset. The new SRS triggering offset value may be partly based on a minimum timing offset for the UE and may be contained in a medium access control (MAC) control element (CE) or in downlink control information (DCI). Additionally, the new triggering offset value may be applicable for a plurality of component carriers or bandwidth parts. The cellular base station may also determine a new triggering offset value due to conflicts regarding the AP-SRS transmission.

Abstract: This disclosure relates to performing beam failure recovery during an inter-cell connection involving a UE in communication with one or more base stations in a cellular communication system. In various embodiments, a user equipment determines one or more beam failures by monitoring one or more reference signals transmitted by one or more base stations, where the UE is connected to the one or more base stations. The UE further performs candidate beam detection by monitoring at least one candidate reference signal that is transmitted by one or more candidate base stations, where at least one candidate base station (a first candidate base station) is different from the one or more base stations to which the UE was previously communicating. The UE selects the first candidate base station based on the candidate beam detection, and transmits a beam failure recovery request (BFRQ) message to the first candidate base station based on the selection.

Abstract: Apparatuses, systems, and methods for multi-TRP by a UE, including out of order delivery of PDSCH, PUSCH, and/or DL ACK/NACK. The UE may receive, from a base station, a configuration that may include multiple control resource set (CORESET) pools and each CORESET pool may be associated with an index value. The UE may determine that at least two DCIs of the multiple DCIs end at a common symbol and determine, based on one or more predetermined rules, when the UE may be scheduled to receive PDSCHs, transmit PUSCHs, and/or transmit ACK/NACKs from CORESETs associated with the at least two DCIs.

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: Systems and methods are provided for handling different timing advance (TA) adjustment delays corresponding to different transmission time intervals (TTIs) from different serving cells under carrier aggregation or dual connectivity. A user equipment (UE) selects and implements one TA adjustment delay even if two or more serving cells transmit with different TTIs. In one embodiment, the UE uses a predetermined TA adjustment delay for each of a plurality of TA commands received from serving cells with different TTI lengths. In another embodiment, the UE uses a TA adjustment delay that is a maximum value of the TA adjustment delays for the TTIs from the different serving cells.

Abstract: The implementations disclosed provide apparatus, systems, and methods for downlink control information (DCI) enhancement for a reduced-complexity new radio (NR) wireless device. The wireless device includes one or more processors configured to transmit a type of the wireless device to a base station communicatively coupled to the wireless device. A format of the DCI is received from the base station. The DCI includes multiple bit strings indicating a schedule of a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH). The format specifies a respective number of bits for each bit string. The format is defined by the base station based on the type of the wireless device. The DCI is received from the base station using a physical downlink control channel (PDCCH). The multiple bit strings are extracted from the DCI based on the format of the DCI.

Abstract: A user equipment (UE) device is configured for performing a signal measurement for wireless communication in a new radio (NR) network. The UE is configured to determine a frequency range (FR) of a serving cell configured to send a signal that is measured by the UE using a signal measurement. The UE configures a measurement gap (MG) pattern to perform the signal measurement. Configuring the measurement gap includes determining that the frequency range of the serving cell includes frequencies of a second frequency range (FR2), determining that a measurement object (MO) configuration for the FR2 is available, setting a measurement gap repetition periodicity (MGRP) value for the signal measurement, and setting a measurement gap length (MGL) value for the signal measurement. The UE performs a signal measurement using the MGRP value and the MGL value.
