摘要:
Techniques for resource block allocation in a multi-user MIMO High Efficiency WLAN system are provided. Specifically, teachings that when taken alone or together, provide a device or a group of devices with an improved resource allocation for the reduction of usable tone waste, are presented. The present disclosure includes a system that provides a user with a technique allocating data tones prior to the encapsulation unit or overhead tones on a resource block unit. Further, the total allocated bandwidth can be reduced prior resource allocation to overcome modulation and coding scheme downgrading caused by severe puncturing. Alternatively, only band edge basic resource blocks are reduced to account for overhead tones which largely reside on band edges.

In embodiments, apparatuses, methods, and storage media may be described for reducing the overhead associated with the transmission of channel training signals from an eNodeB (eNB) of a wireless network. Specifically, the eNB may receive feedback from a user equipment (UE) regarding the received signal energy of a first and second beamformed signal produced with a first and second beamforming vector, respectively. The eNB may identify, based on the feedback of the received signal energy, a signal subspace and a null subspace. The eNB may then transmit a channel training signal to the signal subspace.

A station (STA) may operate as a first peer-to-peer (P2P) client (P2P1) for P2P operations with dual-stage triggering. The STA may decode a primary frame trigger frame (TF) from an access point (AP) operating as a coordinator. The primary TF may allocate resources in an initial portion of a time-duration allocation to the P2P1 for the P2P operations with one or more other peer stations, including a second P2P client (P2P2) and a third P2P client (P2P3). The primary TF may further allocate resources in a subsequent portion of the time-duration allocation to the P2P2 for the P2P operations. The STA may also encode a first secondary TF for transmission within the initial portion of the time-duration allocation. The first secondary TF may allocate specific resource units (RUs) to the one or more other peer stations. The STA may also decode a TB physical layer protocol data unit (TB PPDU) encoded in accordance with a multi-user orthogonal frequency division multiple access (MU OFDMA) frame format. The TB PPDU may be received concurrently within the initial portion of the time-duration allocation from the one or more other peer stations in accordance with an uplink OFDMA technique.

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.

This disclosure describes systems, methods, and devices related to scrambler initialization for multi-user (MU) clear to send (CTS) transmission. A first device may identify a MU request to send (RTS) frame received from a second device. The first device may determine an initial state of a scrambler based on the first 7 bits of a service field of the MU-RTS frame. The first device may cause first data to be scrambled, using the initial state of the scrambler, resulting in second data. The first device may cause to send a MU-CTS frame that comprises the second data to the second device.
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.
