摘要:
Embodiments of a high-efficiency WLAN (HEW) access point (AP), user device (STA), and methods for communication between HEW APs and STAs in a wireless network are generally described herein. In some embodiments, a HEW AP determines a duration of a low-power time allocation, within a beacon period, that is to be reserved for low-power transmissions by STAs within a service range of the AP. The HEW AP can broadcast time sharing information to STAs within the service range of the AP. The time sharing information can indicate a start time of the duration of the low-power time allocation with respect to a start time of the beacon period and a maximum transmission power for transmissions performed during the low-power time allocation. Other embodiments and methods are also described.

In embodiments, apparatuses, methods, and storage media may be described for allocating radio resources to a user equipment (UE) for device to device (D2D) transmission. Specifically, the UE may be configured to predict cellular interference to one or more cellular transmissions in a cell that may be caused by the transmission of a D2D signal. Based on that predicted interference, the UE may identify one or more radio resources in for the D2D transmission.
摘要:
A technology for a user equipment (UE) that is operable to communicate in a device to device (D2D) network. A D2D coordinator selection assignment can be determined. A D2D bandwidth allocation request can be received from at least one D2D UE. Bandwidth can be scheduled for the at least one D2D UE. A D2D bandwidth allocation message can be communicated to at least one D2D UE within the D2D network to enable the at least one D2D UE to determine when bandwidth is allocated for the at least one D2D UE to communicate with another D2D UE in the D2D network.
摘要:
A technology for device to device (D2D) communication scheduling is disclosed. A D2D device can be synchronized with a base station of a cellular system. A sub-frame symbol boundary can be identified in the cellular system for the D2D communication. A resource for a D2D communication can be allocated from the D2D device to another D2D device within the sub-frame boundary of the cellular system. The D2D device can be switched to perform a D2D communication with another D2D device in proximity with the D2D device, wherein the other D2D device is substantially synchronized with the base station of the cellular system. The D2D device can communicate with the other D2D device within at least one symbol boundary time within the selected subframe.

An apparatus and method for the flexible configuration of uplink and downlink ratio by exchanging information relating to user traffic pattern among eNodeBs in a wireless communications network using the X2 interface is disclosed herein. In one embodiment, the information exchanged among the eNodeBs comprises downlink subframe transmission power information and uplink subframe reception power information. In another embodiment, the information exchanged among the eNodeBs comprises downlink subframe loading information and uplink subframe loading information. The exchange of such information facilitates implementation of a flexible or dynamic configuration of the uplink and downlink ratio.

This disclosure describes systems, and methods related to parallel transmission of high efficiency SIGNAL field in communication networks. A device may generate a high efficiency preamble in accordance with a high efficiency communication standard, the high efficiency preamble including, at least in part, one or more legacy SIGNAL fields, one or more high efficiency SIGNAL fields, and one or more channel training fields. The device may cause to send the one or more channel training fields to one or more first devices. The device may determine one or more spatial channel streams associated with at least one of the one or more first devices, the one or more spatial channel streams includes a first stream and a second stream. The device may partition the at least one of the one or more high efficiency SIGNAL fields into, at least in part, a common part and one or more user-specific parts, the one or more user-specific parts includes a first user-specific part and a second user-specific part. The device may cause to send at least one of the one or more user-specific parts using the one or more spatial channel streams.
