Abstract: A radio resource measurement (RRM) and timing configuration (TC) framework can facilitate efficient configuration of RRM measurements in wireless communications systems with variable carrier and transmission bandwidths. The RMTC can comprise a list of synchronization signal (SS) block measurement and timing configurations (SMTCs) and a list of channel state information reference signal (CSI-RS) measurement and timing configurations (CMTCs). A framework is proposed to allow for efficient signaling of measurement configurations in cellular wireless communications systems with overlapping carriers of varying bandwidths comprising carriers without synchronization signals as well as bandwidth parts covering parts of the spectrum of a carrier.

Abstract: Various embodiments disclosed herein provide for multi-stage segmentation of downlink control information. Downlink control information can arrive at a user equipment on more than one channel, setting up and configuring data channels for different base stations, or data channels for the same base station but where the data channels are in different frequency domains or time domains. The downlink control information segmentation system disclosed herein can determine when downlink control information for the user equipment is common across a plurality of downlink control channels, and ensure that the downlink control information is sent just one time, to avoid redundant data transmissions and increased overhead.

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).

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: A method facilitating determination of transmission type via demodulation reference signal (DMRS) patterns is provided. In one example, the method can include generating information according to a protocol for receipt by a mobile device, wherein the information is indicative of a defined transmission type for the mobile device and wherein the protocol employs demodulation reference signal patterns; and transmitting the information to the mobile device. In some embodiments, the protocol comprises a first protocol in which the information comprises a first message transmitted in a first set of resources to communicate to the mobile device a first downlink control information (DCI) format associated with a first transmission type, and wherein the protocol further comprises a second protocol in which the information comprises a second message transmitted in a second set of resources to communicate to the mobile device a second DCI format associated with a second transmission type.
