Abstract: An early termination system for blind decoding is provided to decrease the computational resources utilized when decoding the physical resources, and decrease the time spent decoding. A blind decoding priority list can be used by the mobile device to preferentially decode specific physical resource elements as it specifies the order of all the candidate physical downlink control channels (PDCCHs). When the physical resource elements are decoded, if there is no more downlink control information in that transmission time interval, the downlink control information can include a termination bit, and the mobile device, upon identifying the termination bit can cease blind decoding of the remainder candidates. In this way, the blind decoding process more quickly identifies the downlink control information, and subsequent blind decoding is halted.

Abstract: The described technology is generally directed towards dynamic resource coordination that supports multi-hop based relaying for integrated access and backhaul (IAB) in New Radio (5G). Described is a technology in which an IAB node and a serving parent node use wireless signaling to dynamically adapt downlink and uplink resources used for access and backhaul links. An IAB node receives scheduling data from a parent node, configures a frame structure comprising mobile termination function subframes and distributed unit component subframes, and communicates data based on the frame structure. The parent node explicitly or implicitly indicates that a portion of the scheduling data is adaptable, e.g., sends a dynamic frame structure coordination message. In response, the IAB node can adapt the frame structure into a modified frame structure and can communicate further data based on the modified frame structure.

Abstract: Controlling and reducing overhead in control channels in 5G or other next generation communication systems is provided herein. In connection with a data transmission between a device and a network node device, an overhead management component (OMC) can analyze one or more factors associated with the device, including speed or Doppler metric(s) of the device, type of service associated with the device, historical HARQ statistics for the device, configured threshold value for CSI estimation, device capability regarding redundancy version support, or another factor(s). Based on analysis results, OMC can determine whether to utilize a single redundancy version state or a multiple redundancy versions state. If the single redundancy version state is selected, OMC can generate control information that does not include redundancy version information, the control information being communicated via a control channel OMC can communicate RRC signal to the device to indicate the determined redundancy version state.

Abstract: The technologies described herein are generally directed toward communicating resource information to a local manager of a group of user equipment devices, for allocation of resources to the group. According to an embodiment, a system can comprise a processor and a memory that can store executable instructions that, when executed by the processor, facilitate performance of operations. The operations can include selecting a first group of resources for a group of user equipment devices. The operations can further include communicating, to a first user equipment device of the group of the user equipment devices, first information corresponding to the first group of resources, the first user equipment device being a first local manager of the group, that communicates second information corresponding to a second group of resources, based on the first information, to respective other user equipment devices of the group, other than the first user equipment device.

Abstract: The described technology is generally directed towards wireless communications systems in which multiple control channel resource sets (CORESETs) are configured into a CORESET group. The CORESET group may be associated with a usage scenario/quality of service requirement, and used by user equipment to decode downlink control information corresponding to that usage scenario. For example, one CORESET group can be used for URLLC traffic, another for eMBB type traffic and another for mMTC traffic. Different CORESET groups may be used to provide different aggregation level sets, different DMRS pattern configurations, different search spaces, different transmission protocols/schemes, different beam management and recovery procedures, different radio link monitoring and radio link failure procedures, and so on. Different CORESET groups may be associated with different transmission points.

Abstract: Various embodiments disclosed herein provide for efficient configuration of demodulation reference signals in beamformed wireless communications systems. In an embodiment, the transmitter can signal the location of demodulation reference signals (DMRS) by including an indicator bit in downlink control information indicating which DMRS scheme is used in the transmission. A first DMRS scheme can let the user equipment (UE) device know that the DMRS position for the PDSCH carrying the RMSI is as signaled on the master information block (MIB)—referred to as PDSCH Mapping Type A. A second DMRS scheme can let the UE device know that the DMRS position for the PDSCH carrying the RMSI is the first orthogonal frequency division multiplexing (OFDM) symbol of said PDSCH allocation—referred to as PDSCH mapping type B).
