Abstract: Systems, methods, and circuitries are provided for performing sidelink communication. An example method indicates a frequency resource reservation in sidelink control information (SCI). The method includes identifying a transport block (TB) for transmission to a UE; determining a total number of sub-channels (NSL) in a resource pool for sidelink communication, a number of sub-channels (Lsub) of the TB, a first starting sub-channel index x1 of a first retransmission of the TB, and a second starting sub-channel index x2 of a second retransmission of the TB. The method includes determining a frequency resource indication value (FRIV) based on NSL, LSUB, x1, and x2, wherein the FRIV represents a result of a predetermined function of Lsub, x1, and x2 that generates a unique value for possible combinations of Lsub, x1, and x2. The FRIV is encoded in SCI and the SCI is transmitted to the UE.

Abstract: A method for wireless communication includes: scheduling, by a wireless station, a first uplink (UL) transmission from a wireless device; determining, by the wireless station, a need for a higher priority uplink transmission that uses resources overlapping with the first UL transmission; determining, by the wireless station, a reference region, within which a UL cancellation indication (CI) is to be applied; determining, by the wireless station, a set of UL resources in the reference region for cancellation, wherein at least a subset of the UL resources in the reference region are interlaced; sending, via a downlink control channel, indication of the determined set of UL resources for cancellation (e.g., by indicating particular interlaces and/or particular Physical Resource Blocks within such interlaces that are to be canceled); and receiving, at the wireless station, the higher priority uplink transmission via at least a subset of the determined set of cancelled UL resources.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for Fifth Generation New Radio (5G NR) frequency range two (FR2) based communications beam management. The UE may configure, via communications with a base station, serving the UE, a group ID for PUCCH resources within a group of PUCCHs, e.g., for FR2 based communications. The UE may receive, from the base station, an update to one or more PUCCH resources within the group of PUCCHs via a medium access control (MAC) control element (CE) that may include one of a resource ID indicating an update to a PUCCH resource or the group ID to update the group of PUCCH resources. The UE may update, based on the MAC-CE, the one or more PUCCH resources within the group of PUCCHs.

Abstract: Measurement resources are often limited in 5G and 4G-LTE communications. As a result, SMTC and CSI-RS measurement windows will occasionally be assigned to the same resource elements of a signal frame. This results in a collision that must be resolved, since both measurements cannot be performed simultaneously. The collision can be resolved using restriction, where overlapping resource elements are assigned to either the SMTC or the CSI-RS measurements, or can be resolved using measurement sharing, where overlapping resource elements are divided among the two measurements according to a measurement sharing factor. Various factors, including priority or window periodicity may be taken into account by the measurement rules that dictate collision resolution.

Abstract: Methods and apparatuses are disclosed for calculating and compensating for Doppler shift in a high-speed environment. When in a high-speed environment, Doppler shifts on a transmitted radio frequency signal can become extremely large, which may make it difficult or even impossible for a receiving device to accurately decipher the signal. Therefore, embodiments of the present disclosure describe how tracking reference signals can be transmitted from multiple transmission/reception points, and processed by the UE. For example, the TRS transmitted from the TRP can be enhanced to allow for TRS information from two different TRPs. Additionally, or alternatively, a flag can be set within TRS information that identifies it as having originated from either a first TRP or a second TRP. Additionally, the UE can calculate Doppler shift information and report that information back to the base station in a report message, such as an SRS message. In this manner, the base station can precompensate for the Doppler shift.

Abstract: Techniques described herein involve the use of quasi-co-location (QCL) capabilities and spatial relation assumption to enable a UE to designate a single beam for connections with a base station during a physical random access channel (PRACH) procedure. Once the PRACH procedure is complete, the beam may be reset after a pre-determined duration, which may account for decoding latency, or maintained until additional transmission configuration indication (TCI) is received. Also addressed are scenarios involving multiple transmission reception points (TRPs) and switching between beam management schemes based on one or more factors including device capabilities.

Abstract: A network-controlled repeater (NCR) may receive configuration information from a base station to configure one or more receive (Rx) beams and corresponding time-domain resources for potential reception from one or more user equipments (UEs). The NCR may monitor for reception of a physical uplink channel or signal from the one or more UEs on the configured one or more Rx beams on the corresponding time-domain resources and determine that the physical uplink channel or signal is not received for at least a threshold amount of time. Additionally, the NCR may determine to refrain from at least one of additional monitoring for reception of the physical uplink channel or signal from the one or more UEs or transmission of one or more synchronization signal block (SSBs) to the one or more UEs for a duration of time.

Abstract: This disclosure provides details of sequence-based WUS design and signaling, also DCI-based WUS design which also serves as scheduling DCI. For sequence-based WUS there are two variants. A first is based on CSI-RS, that is relatively wide band so the sequence occupies wider band compared to SSB transmission. The second is more akin to the Secondary Synchronization Signal (SSS) type of sequence in that it occupies a narrower band over the entire bandwidth.

Abstract: This disclosure relates to techniques for performing beam failure recovery and receiving control information with improved reliability in a wireless communication system. The techniques may include the use of multiple beams in conjunction with performing beam failure recovery, for example including identifying multiple candidate beams for beam failure recovery. The techniques may also or alternatively include the use of multiple beams to provide repetitions of control information for search space and control resource set index 0.
