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: 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: A system employing resource element mapping for efficient use of the downlink control channel is provided for a wireless communication system. In one example, a method comprises: generating, by a base station device comprising a processor, resource element mapping signaling, wherein the resource element mapping signaling is performed per subgroup of physical resource blocks of a group of physical resource blocks; transmitting, by the base station device, a first resource element mapping pattern to a first subgroup of the group of physical resource blocks; and transmitting, by the base station device, a second resource element mapping pattern to a second subgroup of the group of physical resource blocks, wherein the first resource element mapping pattern is distinct from the second resource element mapping pattern.

Abstract: A system facilitating compact signaling design for reserved resource configuration via a multi-dimensional bitmap is provided for a wireless communication system. A method comprises: determining a multi-dimensional bitmap (MDB) in time and frequency domains, wherein the time domain is represented by an orthogonal frequency division multiplexed (OFDM) symbol and the frequency domain is represented by an OFDM subcarrier. The determining comprises: selecting a group of reserved resource allocations of the MDB in which data information is not to be communicated; assigning a first value for the OFDM multiplexed symbol and the OFDM subcarrier according to a location of elements of the group of reserved resource allocations; and assigning, to other portions of the MDB other than the group of reserved resource allocations, a second value distinct from the first value. The method also comprises facilitating, by the device, transmitting the MDB to a mobile device.

Abstract: Aspects of the technology described herein are directed towards using generic control information in a three-party wireless communication system to schedule a data transmission and reception of the data transmission. A scheduler node transmits the generic control information, comprising identification information that identifies a user equipment device as a transmitter node, and scheduling information that schedules a data transmission. For unicast data transmissions, the generic control information further identifies a receiver node, and can schedule transmission of an ACK/NACK from the receiver node corresponding to receiving the data transmission. A control procedure can be configured in a user equipment device by linking a channel configuration dataset to a resource configuration dataset, which in turn is linked to a channel transmit and receive configuration dataset. Reconfiguration is achieved by changing the linking(s) between one or more different available datasets.
