Abstract: Some embodiments of this disclosure include apparatuses and methods for multiplexing uplink (UL) and/or downlink (DL) data transmission packets in user equipment (UE). In some embodiments, the UE may receive a resource configuration from a network node including one or more parameters for establishing a communication channel. The UE may receive a command from the network node indicating a UL grant for packet transmission from the UE. While preparing to transmit a first packet corresponding to the UL grant, the UE may receive a second packet having a higher priority designation, wherein the second packet includes an overlapping symbol with the first packet. The UE may transmit the second packet in view of this higher priority.

Abstract: Some embodiments of this disclosure include apparatuses and methods for providing semi-static integrated access backhaul (IAB) resource configurations in an IAB network. For instance, a central unit (CU) of an IAB donor can provide, to a distributed unit (DU) of an IAB node, F1 application protocol (F1AP) signaling data indicative of a semi-static IAB resource configuration regarding at least one of downlink resources, uplink resources, or flexible resources. The semi-static IAB resource configuration indicates whether the at least one of downlink resources, uplink resources, or flexible resources are hard resources, soft resources, or not available resources. The CU can further provide, to a mobile termination (MT) of the IAB node, radio resource control (RRC) signaling data indicative of the semi-static IAB resource configuration.

Abstract: Techniques discussed herein can facilitate multi-transmission reception point (multi-TRP) operation for new radio (NR). One example apparatus may be employed at a user equipment (UE) and may comprise one or more processors configured to transmit uplink control information (UCI) on two physical uplink control channels (PUCCHs). The two PUCCHs occupy different symbols in the same slot.

Abstract: A base station may generate first configuration information to configure a first user equipment (“UE”) to operate using a first bandwidth within a wideband carrier of a cell, generate second configuration information to configure a second UE to operate using a second bandwidth within the wideband carrier of the cell, and cause transmission of the first and second configuration information to the first and second UEs, respectively. The base station may configure the first and second UEs based upon capabilities received from each UE, respectively.

Abstract: A device, system, method, machine readable medium. The method includes: decoding a physical downlink control channel (PDCCH) from a Node B, the PDCCH scheduling a physical downlink shared channel (PDSCH); determining at least one of a control resource set (CORESET) index or a starting control channel element (CCE) index of the PDCCH; decoding the PDSCH; determining, based the at least one of the CORESET index or the CCE index, a physical uplink control channel (PUCCH) resource to carry hybrid automatic repeat request (HARQ) acknowledgment (ACK) (HARQ-ACK) feedback corresponding to the PDSCH to the Node B; and causing transmission of the HARQ-ACK feedback based on the PUCCH resource.

Abstract: A user equipment wireless communication device in a wireless communication environment receives a signal from the network that includes a radio network temporary ID. From the radio network temporary ID, the user equipment is capable of determining whether a phase tracking reference signal is present based on the radio network temporary ID. If any of these are identified by the radio network temporary ID, then the user equipment determines that a phase tracking reference signal is present. After the user equipment has determined that the phase tracking reference signal is present, the user equipment can then determine which phase tracking reference signal antenna ports are to be used based on the values of the transmitted precoding matrix indicator value and the transmit rank indicator.

Abstract: An approach is described for a base station (gNB) that includes the following features. The features include transmitting, by the gNB, a PDCCH signal to a user equipment (UE), wherein the PDCCH signal includes an indication of a PDCCH ordered 2-step RACH procedure. The features also include receiving, by the gNB, a first step of the 2-step RACH procedure, wherein the first step includes a PRACH preamble and an associated MsgA physical uplink shared channel (PUSCH) from the 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.
