Abstract: Techniques for physical downlink shared channel (PDSCH) and physical uplink shared channel (PUSCH) processing for multiple transmission and reception point (multi-TRP) are disclosed. In some embodiments, determining PDSCH hybrid automatic repeat request-acknowledgement (HARQ-ACK) processing timing may include determining that a user equipment (UE) is configured for single downlink control information (single-DCI) multi-TRP PDSCH operation, determining a first PDSCH and a second PDSCH within a slot, wherein the first PDSCH and the second PDSCH are used in the single-DCI multi-TRP PDSCH operation, and determining a minimum HARQ-ACK processing timing for the first PDSCH and the second PDSCH using one or more symbols of the first PDSCH or one or more symbols of both the first PDSCH and the second PDSCH.

Abstract: An evaluating user equipment (UE) includes memory and one or more processors communicatively coupled to the memory. The one or more processor are configured to schedule periodic resources with one or more configured feedback-based collision detection parameters, and perform a periodic transmission to one or more receiving UEs. The one or more processors are also configured to collect negative acknowledgement (NACK) statistics for the periodic transmission according to the configured feedback-based collision detection parameters, and selectively perform corrective action based on the collected NACK statistics and at least one of the configured feedback-based collision detection parameters.

Abstract: A device may obtain, through wireless signaling from a network, a time-domain wireless-resource allocation (TWRA) pattern allocated to the device by the network and corresponding to a future time interval (TTI) for which the device has not yet decoded corresponding control information. This enables the device to conduct wireless communications during the TTI using resources allocated according to the obtained TWRA pattern, without first having to decode control information to identify the TWRA pattern. The device may obtain the TWRA pattern by obtaining an indication from the network that the TWRA pattern remains associated with future wireless communications of the device until indicated otherwise by the network, and/or by transmitting to the network an indication of preferred parameters associated with the future wireless communications and the TWRA pattern, and/or by transmitting to the network a request to have the network change from a different TWRA pattern to the TWRA pattern.

Abstract: A user equipment (UE) passively determines the presence of a cellular network bottleneck in a downlink channel and may take appropriate actions to mitigate the bottleneck. The UE may analyze the transport block size (TBS) of slots of received downlink traffic and assign states the to various slots based on this analysis. Based on these assigned states, the UE may identify a burst of network traffic from network traffic received from the cellular network, and the UE may also determine the burst duration as well as a busy estimation. The UE may determine that the cellular network is experiencing a bottleneck based at least in part on the burst duration and the busy estimation.

Abstract: Apparatuses, systems, and methods to indicate power transmission capability for a wireless device. A wireless device may connect to a base station (BS). The wireless device may transmit information regarding transmit power capability to the BS. The wireless device may indicate support for full power transmit capability for a subset of TPMIs for which it provides full power transmit capability, e.g., in a bitmap. This subset of TPMIs may be less than all of the available TPMIs (i.e., it may be a strict subset of the available TPMIs). Full power transmission capability of these indicated TPMIs may be provided via antenna switching and/or antenna virtualization. The wireless device may perform uplink transmission to the BS according to the transmit power capability indicated in the information. For example, the UE may transmit data using the antenna virtualization related to the subset of the TPMIs.

Abstract: Systems, methods, and circuitries are provided for performing sidelink communication. An example method generates SCI stage 1 and stage 2 for transmitting a transport block (TB) to a user equipment device (UE). The method includes determining the type of sidelink communication for transmitting the TB. An SCI stage 2 format is selected based on the type of sidelink communication. An SCI stage 2 payload is encoded in accordance with the selected SCI stage 2 format. The selected SCI stage 2 format value is encoded in an SCI stage 1 payload. The SCI stage 1 payload and SCI stage 2 payload are transmitted to the UE.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform multiple TTI PUSCH transmissions in a wireless communication system as well as code block groups (CBGs) based retransmissions operations. A UE may perform radio resource control (RRC) signaling with a network entity to configure a data structure that may include one or more sets of physical uplink shared channel (PUSCH) transmission configurations, where each set of PUSCH transmission configurations span multiple TTIs. The wireless device may be configured to receive, from the network entity, a downlink control information (DCI) message that may include a time domain resource assignment field (TDRA) that may indicate a set of PUSCH transmission configurations included in the data structure. The wireless device may perform PUSCH transmissions spanning multiple TTIs according to the indicated set of PUSCH transmission configurations over an unlicensed band.
