Abstract: To extend a physical broadcast channel (PBCH) in wireless communications, an extended physical broadcast channel (EPBCH) transmission is generated with one or more legacy PBCH blocks and one or more EPBCH blocks within an extension window. A size of the extension window is determined based at least in part on a PBCH repetition number and a number of the legacy PBCH blocks relative to a number of the EPBCH blocks. The EPBCH transmission is transmitted by a base station (BS) to one or more user equipment (UE).

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: 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: Systems, apparatuses, methods, and computer-readable media are provided for user equipment (UE) idle mode operations. In embodiments, a UE wakes up more than once during a Discontinuous Reception (DRX) cycle. Inter-frequency measurement requirements may be relaxed based on DRX cycle length. Some embodiments include radiofrequency (RF) circuitry warm-up overhead reduction by on-duration separation with RF circuitry switching pattern adaption. Some embodiments include and RF circuitry warm-up overhead reduction by adaptive synchronization signal block (SSB) reference symbol down-selection. Other embodiments may be described and/or claimed.

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: A user equipment (UE) is configured to establish a network connection including a new radio (NR)-NR dual connectivity band combination wherein a primary cell (PCell) of a primary cell group (PCG) and a primary secondary cell (PSCell) of a secondary cell group (SCG) both operate on frequency range 1 (FR1) and wherein at least one cell of either the PCG or the SCG operates on frequency range 2 (FR2). The UE receives a measurement gap timing advance parameter, selects one subframe from multiple serving cell subframes and determines a starting point for a configured per-frequency range (FR) measurement gap based on the measurement gap timing advance parameter and the selected subframe.
