A split of radio protocols is applied within a cellular base station, between at least one virtualization platform connected through user data interfaces to Radio Transceiver Points (R-TP) serving a UE. It is provided a header for transporting a QoS information value, belonging to a set including a delay budget under 50 ms, related to at least one data packet transmitted to the given UE by a specific application. The header and the data packet are tunneled to the R-TP serving the UE. A control interface, conveying QoS requirements of the specific application, is established between a Central Controller or a Central Coordinator of the base station and the serving R-TP. The data packet is transmitted over the air to the given UE, being scheduled while considering the QoS information included within the provided header and the conveyed QoS requirements.

Methods, computer readable media, and apparatuses are disclosed for spatial reuse. A high efficiency station (HE STA) that includes circuitry is disclosed. The circuitry may be configured to: determine if a link with a wireless device is a D2D link with a spatial reuse opportunity; and transmit a packet that includes an indication that there is the spatial reuse opportunity for the duration of the packet, if the link with the wireless device is the D2D link with the spatial reuse opportunity. The circuitry may be configured to: receive a packet from a second HE STA, where the packet includes an indication that there is a spatial opportunity for the duration of the packet; adjust at least one of the following group: a transmit power and a clear channel assessment parameter; and transmit a second packet to a wireless device in the spatial opportunity in accordance with D2D communication.

In one novel aspect, multiple TRPs information are provided for REG bundle configuration with PDCCH transmission and reception with multiple transmission points (TRPs). The UE configures a PDCCH associated with a CORESET comprising multiple CCEs, partitions the CORESET into multiple CCE groups associated with corresponding TCI-state, which corresponds to a source TRP, configures multiple resource element group (REG) bundles each with multiple resource elements (REs), and assumes the same precoder applied on PDCCH DMRS when the REs are in the same REG bundle and are associated with the same source TRP, and wherein each source TRP transmits corresponding portion of DCI data mapping to the corresponding first and second CCE group. In one embodiment, the REG bundles are predefined with each comprises only REs associated with the same source TRP. In another embodiment, each CCE group corresponding to a source TRP is indicated for the REG bundle configurations.

Aspects of the disclosure relate to Layer 1/Layer 2-centric inter-cell mobility systems and determining timing advance groups (TAGs) within such systems. User equipment (UE) are configured to report one or more grouping of cells to a radio access network (RAN), where the cells for each group have similar propagation delays and/or signal quality. Each reported group can be assigned to a TAG identifier (ID) by the RAN. The RAN may utilize the TAG IDs to time division multiplex uplink and/or downlink transmissions based on the TAG IDs.
