Disclosed are systems, apparatuses, methods, and computer-readable media for use in a wireless network for facilitating radio access synchronization. The method includes receiving, from a user equipment (UE) a message having a media access control (MAC) control element (CE) format and comprising a MAC protocol data unit (PDU) structure, the message being formed by multiplexing one or more MAC service data units (SDUs). The method further includes generating a response message to the received message by multiplexing a MAC random access response (RAR) with one or more MAC SDUs. The method then transmits the response message to the UE.

Apparatus and method for generating mac format for messaging in a two-step random access procedure

Some demonstrative embodiments include devices, systems and/or methods of communication over common control channels. For example, an apparatus may include logic and circuitry configured to cause a User Equipment (UE) to determine a selected Common Control Channel (CCCH) message configuration from a first predefined message configuration and a second predefined message configuration, the first predefined message configuration having a first predefined message bit-size, the second predefined message configuration having a second predefined message bit-size; to generate an Uplink (UL) CCCH message according to the selected CCCH message configuration, the UL CCCH message comprising a Medium Access Control (MAC) header comprising a Logical Channel Identify (ID) (LCID) field having a value corresponding to the selected CCCH message configuration; and to transmit the UL CCCH message to a Next Generation Node B (gNB) over a logical channel corresponding to the selected CCCH message configuration.

Apparatus, system and method of communication over common control channels

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.

System and method for phase tracking reference signal dynamic presence in ultra-reliable and low-latency and port indication

Techniques to configure a user equipment (UE) for a multi-connectivity handover with a source base station (SBS) and a target base station (TBS) include encoding a measurement report for transmission to the SBS. The measurement report is triggered based on a measurement event configured by the SBS. Radio resource control (RRC) signaling from the SBS is decoded, the RRC signaling including a handover command in response to the measurement report. The handover command includes an indication for multi-connectivity support by the SBS and the TBS during the handover. A first protocol stack associated with the SBS and a second protocol stack associated with the TBS are configured at the UE. A packet data convergence protocol (PDCP) protocol data unit (PDU) received at the UE during the handover is processed using the first protocol stack or the second protocol stack.

PDCP and ROHC handling for multi-connectivity handover

A method and device are disclosed for performing collision resolution in a two-step random access channel (RACH) process. In such a process, an MsgA PUSCH signal and a grant based PUSCH signal may collide. When such a collision is detected, either the MsgA PUSCH signal or the grant based PUSCh signal are dropped. The other of the two signals is then transmitted. The determination regarding which signal to drop can be based on a set of rules stored in memory.

On collision handling of MsgA PUSCH in 2-step RACH and other uplink channels

Techniques discussed herein can facilitate beam failure recovery (BFR) for a Secondary Cell (SCell) or Primary SCell (PSCell). One example embodiment comprises an apparatus configured to be employed in a User Equipment (UE), comprising: one or more processors configured to: generate a Physical Random Access Channel (PRACH) associated with a beam failure recovery request (BFRQ); generate a Physical Uplink Shared Channel (PUSCH) message associated with the BFRQ, wherein the PUSCH message comprises at least one Medium Access Control (MAC) Control Element (CE) that comprises one or more of an index associated with a cell for which beam failure was detected or an index associated with a new beam; and process a Physical Downlink Shared Channel (PDSCH) as a random access response (RAR) associated with the PRACH and the PUSCH message.

Beam failure recovery

Technology for a user equipment (UE), operable for monitoring a physical downlink control channel (PDCCH) is disclosed. The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein the predetermined monitoring occasion has a periodicity of P slots or P symbols with an offset O. The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein Ohas an offset with respect to a first slot in subframe number zero (SFN #0). The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein P is a positive integer greater than zero.

Support of flexible PDCCH monitoring in new radio (NR)

Embodiments described herein relate generally to a communication between a user equipment ('UE') and a plurality of evolved Node Bs (“eNBs”). A UE may be adapted to operate in a dual connected mode on respective wireless cells provided by first and second eNBs. The UE may be adapted to estimate respective power headroom (“PHR”) values associated with simultaneous operation on the first and second wireless cells. The UE may cause the first and second PHR estimates to be transmitted to both the first and second eNBs. The first and second eNBs may use these estimates to compute respective uplink transmission powers for the UE. Other embodiments may be described and/or claimed.

Power headroom reporting with dual connectivity

Embodiments of a User Equipment (UE) to support dual-connectivity with a Master Evolved Node-B (MeNB) and a Secondary eNB (SeNB) are disclosed herein. The UE may receive downlink traffic packets from the MeNB and from the SeNB as part of a split data radio bearer (DRB). At least a portion of control functionality for the split DRB may be performed at each of the MeNB and the SeNB. The UE may receive an uplink eNB indicator for an uplink eNB to which the UE is to transmit uplink traffic packets as part of the split DRB. Based at least partly on the uplink eNB indicator, the UE may transmit uplink traffic packets to the uplink eNB as part of the split DRB. The uplink eNB may be selected from a group that includes the MeNB and the SeNB.

User equipment and methods of bearer operation for carrier aggregation

An apparatus and system for reducing URLLC latency are described. A single packet mode is described in which, when a packet arrives at the PDCP layer for transmission, an indication is sent to a scheduler with the expected size of the packet after ciphering. The packet is then sent to the RLC layer and concurrently submitted to the ciphering engine to enable ciphering to occur in parallel with the other activities. The scheduler determines the expected TB size for transmission of the packet by determining the size of the PDCP, MAC, and RLC headers. The scheduler matches the resource allocation for transmission to the expected TB size.

Latency reduction in 5G and 6G networks

Disclosed are methods, systems, apparatus, and computer programs for providing a network with assistance information from a user equipment (UE) that is participating in a multimedia telephony session. In one aspect, a method includes determining a connection parameter of a multimedia telephony session between a user equipment (UE) and a remote UE. The method further includes generating assistance information based on the connection parameter. Yet further, the method include sending, using a medium access control (MAC) control element, the assistance information to an access node (AN) serving the UE.

User equipment assistance information for voice over cellular

An apparatus of a next generation Node B (gNB) Distributed Unit (DU) comprises one or more baseband processors to transmit one or more retransmitted Packet Data Convergence Protocol (PDCP) Protocol Data Units (PDUs) received from a gNB Central Unit (CU) to a user equipment (UE), and to feed back not only a latest, in-sequence New Radio User-plane (NR-U) Sequence Number (SN) to the CU for Release 15, but also a highest, in-sequence successfully delivered/transmitted PDCP SN, optionally, with a NR-U SN up to which the reported PDCP SN should be applied, which can provide an exact range of successfully delivered/transmitted status for retransmitted packets even in case of DU's re-ordering based on PDCP SN before transmitting to the UE. The apparatus can include a memory to store the reported PDCP SN and NR-U SN.
