Abstract: Various nodes in a 3GPP network, including a user equipment (UE), can be used to insert metadata in uplink traffic so that the network and/or an (S)Gi-LAN can make traffic steering decisions based on the metadata. For example, the UE can insert metadata into its uplink traffic so that the services in the (S)Gi-LAN can be better leveraged. Network nodes are able to insert metadata that relates directly to the UE and that relates to the operating conditions of the network nodes that the UE is using to send uplink data, so that the services in the (S)Gi-LAN can be better leveraged.

Abstract: Hybrid automatic repeat request (HARQ) processes may be transmitted via configured grants as well as scheduled grants. The configured grants may include time and frequency resources, and transmissions may occur across contiguous transmissions. HARQ process information, such as HARQ IDs and redundancy versions, may be communicated via a control channel, and the control channel may be multiplexed with the transmission resources of the configured grants. Retransmission timers may be used for HARQ processes conveyed via configured grants, and the transmitting apparatus may signal to a receiver when to send an acknowledgement. An acknowledgement may take the form of bitmaps for code block groups of a HARQ. A configured grant may be selected from among multiple configured grants based upon low latency, for example. A group of configured grants may be activated or deactivated via a single command.

Abstract: An electronic device that is configured to schedule transmission of data to at least one other electronic device via sidelink resources in a wireless communication network; identify that the scheduled transmission of the data is preempted by another transmission occurring within at least a part of the sidelink resources; and control transmission of the data to at least one other electronic device based on the identifying.

Abstract: Methods, systems, and apparatuses are described herein for beamforming based initial access, beam management, and beam based mobility designs for NR systems. Issues are identified and addressed related to one or more of initial access, control channel design, eMBB and URLLC mixing, and beam training. The methods, systems and apparatus may include a receiving scheduling information and a preemption indication via a DCI. In addition, there may be a detecting and decoding of the preemption indication, a determining of a HARQ feedback associated, and a sending, to a network node, of the HARQ feedback.

Abstract: The present application is at least directed to an apparatus including a non-transitory memory with stored instructions for beam link pairing the apparatus to a gNB in a new radio. A processor of the apparatus, operably coupled to the non-transitory memory, executes an instruction of detecting synchronization signal blocks (SS). Another executed instruction includes receiving PRACH resource information in a master information block on a PBCH or system information block (SIB) on the secondary PBCH. Another executed instruction includes transmitting PRACH preambles through a set of uplink transmission beams in a subframe including the group of SS blocks. The PRACH preambles may be obtained from the PRACH resource information. Even another executed instruction including determining the apparatus is in a radio resource control (RRC) connected state. A further executed instruction includes measuring, while in the RRC connected state, a multiple set of channel state information reference signals (CSI-RSs) configured by the gNB. Yet a further executed instruction includes transmitting, to the gNB, a single report based on the multiple set of CSI-RSs.

Abstract: The present application describes a WTRU including a non-transitory memory including instructions stored thereon for re-establishing a remote radio control (RRC) connection with a base station. The apparatus also includes a processor capable of executing instructions of determining, based upon a measurement in an active downlink bandwidth part (DL BWP), to initiate a random access channel (RACH) procedure. The processor also executes instructions of switching to a default uplink bandwidth part (UL BWP). The processor also executes instructions of initiating the RACH procedure. The process further executes instructions of transmitting a RA preamble using one of the RACH resources configured for the default UL BWP. The processor even further executes instructions of receiving a RA response. The processor yet even further executes instructions of switching from the default UL BWP to either an active UL BWP or another active UL BWP after re-establishing the RRC connection.

Abstract: New radio download numerology allocation information may be obtained through master information block data, system information block data, radio resource control signals, or signals or a physical downlink numerology indication channel, and used along with a reference signal detected in a search space to obtain resource element positions in an antenna port reference signal in a resource block that belongs to a particular band slice according to a reference signal allocation scheme for a band slice numerology. A physical download control may then be decoded based upon one or more resource elements of the reference signal, allowing the connection of, e.g., an enhanced mobile broadband, massive machine type communication, or ultra-reliable/low-latency application to a communications network thereby. Alternatively, multiple physical downlink control channels may be blindly demodulated at each of a number calculated reference signal locations, and one channel selected based on passing a cyclic redundancy check.

Abstract: An apparatus includes a processor, a memory; and communication circuitry, the apparatus being connected to a communications network via the communication circuitry, the apparatus further including computer-executable instructions stored in the memory which, when executed by the processor, causes the apparatus to identify an apparatus capability that is an indication of an ability of the apparatus to perform beam failure detection (BFD) for a plurality of cells, transmit the apparatus capability to an other apparatus, receive from the other apparatus at least one message including a change in network configuration; and substitute a second set of cells for the first set of cells on which the apparatus performs BFD based on the change in network configuration so the apparatus capability is not exceeded by the network configuration.
