Abstract: Technology is disclosed for a user equipment (UE) operable for wake-up signal (WUS) communication in a fifth generation (5G) new radio (NR) network. The UE can be configured to: identify a resource set for a WUS with a repetition level, wherein: the resource set for the WUS includes a mapping of the WUS that associates the WUS with one or more physical resource blocks and one or more orthogonal frequency division multiplexing (OFDM) symbols, and the repetition level identifies a number of base sequences for the WUS in the resource set; and switch to a network access mode (NAM) from a power saving mode (PSM) based on a detection of the WUS in the resource set.

Abstract: A user equipment (UE) may increase the reliability of transmission of a Physical Uplink Control Channel (PUCCH) by transmitting repeated copies of the PUCCH, according to a repetition pattern spanning one or more slots. In an intra-slot mode, more than one copy may be transmitted within each configured slot, with or without frequency hopping. The number of copies as well as a temporal gap between the transmission of successive copies may be configured by the network. The repetition pattern may or may not be interrupted by slot boundaries. In an inter-slot mode, one copy is transmitted per configured slot. Different copies may be transmitted in different directions, according to a spatial consistency pattern. The UE may perform repeated transmission of PUCCHs to different Transmission-Reception Points (TRPs) using respectively different timing advances and/or transmit power levels.

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: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may receive a physical downlink control channel (PDCCH) that schedules a physical downlink shared channel (PDSCH) in a slot, and on a component carrier (CC) of a plurality of CCs. The PDCCH may include a total downlink assignment index (DAI) and a counter DAI for hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback of the PDSCH. The total DAI may indicate a total number of pairs of CCs and slots for the HARQ-ACK feedback. The UE may encode the HARQ-ACK feedback to include a bit that indicates whether the PDSCH is successfully decoded. A size of the HARQ-ACK feedback may be based on the total DAI, and a position of the bit may be based on the counter DAI.

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 DCL In particular, the single control element may signal resources scheduled for transmission of acknowledgment feedback information for all of the PDSCH TBs. Various approaches are disclosed, with varying levels of signaling overhead.

Abstract: Apparatuses, systems, and methods for performing multi-TRP transmissions using techniques for reducing wireless device power consumption. A wireless device may select a downlink signal buffering method for a communication slot. The downlink signal buffering method may be selected from a single antenna panel signal buffering method or a multi-antenna panel signal buffering method. One or more beams for which to perform downlink signal buffering for the communication slot may be selected based at least in part on the downlink signal buffering method selected. Downlink signals may be received from one or more cellular base stations during the communication slot using the selected one or more beams. The downlink signals received using the selected one or more beams may be buffered by the wireless device.

Abstract: A service device (e.g., a user equipment (UE), a new radio NR (gNB), or other network component) as a service provider/consumer can process or generate sidelink communications based on a downlink control information (DCI) for one or more sidelink configured grants that enables resource allocation for the sidelink communication. The device can determine whether to activate, release/deactivate, or request a retransmission for the one or more sidelink configured grants based on one or more fields of a DCI format 3_0 configuration of the DCI.

Abstract: A wireless device may establish communication with a network node and determine a relationship between transmission configuration indication (TCI) and bandwidth part (BWP). The wireless device may then receive an indication of one of TCI or BWP from the network node followed by determining the other of TCI or BWP based on the indication and using the relationship between the TCI and BWP. Finally, the wireless device may perform downlink communication using the indicated one of TCI or BWP and determined other TCI or BWP. The network node may be comprised in a non-terrestrial network and may specify via RRC signaling the relationship between TCI and BWP for the wireless device. The indication of the TCI or BWP may be provided by downlink control information (DCI), medium access control (MAC) control element (CE), an inactivity timer, or RRC reconfiguration commands.
