Abstract: A system and method for multiplexing traffic. A wireless device such as a user equipment (UE) may receive a first signal over first resources assigned to carry a first downlink transmission from a base station, and receive a first downlink control indication (DCI) message from the base station. The first DCI message may include a pre-emption region (PR) indication and a PR bitmap, and the PR indication may indicate a location of a time-frequency region. The PR bitmap may include bits associated with different portions of the time-frequency region, and each of the bits in the PR bitmap may indicate whether a preemptive downlink transmission is present in the corresponding portion of the time-frequency region.

Abstract: Soft information for achieving interference cancellation in downlink transmissions can be communicated over device-to-device (D2D) links, thereby allowing paired user equipments (UEs) to receive downlink transmissions over the same radio resources. More specifically, paired UEs that receive transmissions over the same time-frequency resources may exchange soft or hard information over D2D links in order to facilitate interference cancellation. The D2D links may be unidirectional or bidirectional, and may be established over in-band or out-of-band resources. Paired UEs may be in the same or different cells, and may receive their respective transmissions from the same or different transmit point. UEs may be paired with one another based on various criteria, e.g., interference cancellation capabilities, scheduling metrics, etc.

Abstract: Embodiments of the present application pertain to control information for scheduling a transmission resource for downlink and uplink communications between one or more TRP and one or more UE. One Physical Downlink Control Channel (PDCCH) for DL control information transmission is assumed to carry at least one assignment or scheduling information block for at least one Physical Downlink Shared Channel (PDSCH) for DL data transmission or for at least one Physical Uplink Shared Channel (PUSCH) for UL data transmission. Embodiments of the present application provide methods of providing configuration information that can be used by a user equipment (UE) to determine transmission mode for the PDSCH and PUSCH as well as information to determine where to monitor for the PDSCH, PUSCH and PUCCH information.

Abstract: A base station may transmit downlink control information (DCI) scheduling communications between the base station and a UE. The DCI is in a fallback DCI format. Based on whether or not the DCI is in a UE specific search space with cyclic redundancy check (CRC) scrambled by a UE ID of the UE, data transmitted by the base station or by the UE according to the DCI may be scrambled by a sequence that is initialized with a configurable parameter, or initialized with a cell ID.

Abstract: Virtualized group-wise communications between a wireless network and a plurality of user equipments (UEs) are supported using UE cooperation. UE cooperation includes receiving, at a cooperating UE (CUE), downlink information from the wireless network destined for a target UE (TUE) and associated with a group identifier (ID). The group ID indicates a virtual multi-point (ViMP) node that includes the TUE and the CUE. The UE cooperation also includes sending the downlink information to the TUE. The UE or UE component can have a processor configured to forward between the wireless network and a TUE at least some information that is associated with a group ID indicating a ViMP node that groups the TUE and the UE.

Abstract: In a wireless (e.g., machine-to-machine) network, items of user equipment compete for wireless communication resource slots (“resources”). In a contention period, an item of user equipment (a UE) sends a first signal to a base station using a first resource. The first resource is mapped to a second resource in a data transmission period. If the base station successfully receives the first signal, it sends a second signal to the UE to confirm that the UE has been awarded the second resource and can transmit data in the data transmission period.

Abstract: Aspects of this disclosure provide techniques for computing Vandermonde-subspace frequency division multiplexing (VFDM) precoders for secondary network transmissions that mitigate interference between secondary communication signals, while avoiding interference with the primary system altogether. A precoder for a secondary user (SU) is computed on accordance with a nullspace induced by cyclic prefixes communicated over a primary data channel, a primary interference channel between a second user (SU) and the primary receiver, and a secondary interference channel between the SU and a neighboring SBS. The precoder provides both frequency domain precoding and spatial domain precoding on secondary transmission signals communicated from the SU.
