In one example, controller 154, message processor 158, and radio 144 may be implemented as part of the chip or SoC.

[0098] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may operate as and/or perform the functionality of a device or station, for example, an awareness networking device, a NAN device, a WiFi device, a WiFi Aware device, a WFD device, a WLAN device, a Low Power Long Range (LPLR) device, and/or any other device, capable of discovering other devices according to a discovery protocol and/or scheme.

[0099] In some demonstrative embodiments, radios 114 and/or 144 may communicate over wireless communication medium 103 according to an awareness networking scheme, for example, a discovery scheme, for example, a WiFi Aware discovery scheme ("NAN discovery scheme"), and/or any other awareness networking and/or discovery scheme, e.g., as described below.

[00100] In some demonstrative embodiments, the awareness networking scheme, e.g., NAN, may enable applications to discover services in their close proximity. For example, the NAN technology may be a low power service discovery, which may, for example, scale efficiently, e.g., in dense Wi-Fi environments.

[00101] In some demonstrative embodiments, a device, e.g., one or more of wireless communication devices 102, 140, 160 and/or 180, may include one or more blocks and/or entities to perform network awareness functionality. For example, a device, e.g., one or more of devices 102, 140, 160 and/or 180, may be capable of performing the functionality of a NAN device, which may include a NAN MAC and/or a Discovery Engine (DE). In one example, controllers 124 and/or 154 may be configured to perform the functionality of the discovery engine, and/or message processors 128 and/or 158 may be configured to perform the functionality of the NAN MAC, e.g., as described above. In another example, the functionality of the NAN MAC and/or the Discovery engine may be performed by any other element and/or entity of devices 102, 140, 160 and/or 180.

[00102] In some demonstrative embodiments, the awareness networking scheme may include a discovery scheme or protocol, e.g., as described below.

[00103] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may perform a discovery process according to the awareness networking scheme, for example, to discover each other and/or to establish a wireless communication link, e.g., a directional and/or high throughput wireless communication link and/or any other link. [00104] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may be configured to enable time synchronization between devices 102, 140, 160, 180 and/or one or more other devices, e.g., performing the functionality of Wi-Fi stations (STAs), for example, such that STAs can discover each other more efficiently and/or quickly.

[00105] Some demonstrative embodiments are described below with respect to a NAN discovery scheme, and to NAN discovery frames of the NAN discovery scheme. However, in other embodiments, any other discovery scheme and/or discovery frames may be used.

[00106] In some demonstrative embodiments, the discovery scheme may include a plurality of contention-based discovery windows (DWs).

[00107] In some demonstrative embodiments, communication during the DWs may be configured to enable time synchronization between Wi-Fi stations (STAs), e.g., devices 102, 140, 160 and/or 180, so that STAs can find each other more efficiently during a DW.

[00108] In some demonstrative embodiments, devices of an awareness network, e.g., a NAN network, may form one or more clusters, e.g., in order to publish and/or subscribe for services. A NAN cluster may be defined by an Anchor Master (AM) (also referred to as a "NAN master device" or "anchor device"). In one example, the AM may include a NAN device, which has the highest rank in the NAN cluster.

[00109] In some demonstrative embodiments, NAN data exchange may be reflected by discovery frames, e.g., Publish, Subscribe and/or Follow-Up Service discovery frames (SDF). These frames may include action frames, which may be sent by a device that wishes to publish a service/application, and/or to subscribe to a published service/application at another end.

[00110] In one example, one of devices 102, 140, 160 and/or 180, e.g., device 102, may operate as and/or perform the functionality of an AM. The AM may be configured to transmit one or more beacons. Another one of devices 102, 140, 160 and/or 180, e.g., device 140, may be configured to receive and process the beacons.

[00111] In one example, devices 102, 140, 160 and/or 180 may operate as and/or perform the functionality of NAN devices, e.g., belonging to a NAN cluster, which may share a common set of NAN parameters, for example, including a common NAN timestamp, and/or a common time period between consecutive discovery windows (DWs). The NAN timestamp may be communicated, for example, as part of a NAN beacon frame, which may be communicated in the NAN cluster. In one example, the NAN timestamp may include a Time Synchronization Function (TSF) value, for example, a cluster TSF value, or any other value. [00112] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may be configured to discover one another over a predefined communication channel ("the social channel"). In one example, the Channel 6 in the 2.4GHz band may be defined as the NAN social channel. Any other additional or alternative channel may be used as the social channel.

[00113] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may transmit discovery frames, e.g., SDFs, during the plurality of DWs, e.g., over the social channel and/or any other channel, which may be used for discovery. For example the NAN AM may advertize the time of the DW, during which NAN devices may exchange SDFs.

[00114] In one example, devices 102, 140, 160 and/or 180 may transmit the discovery frames to discover each other, for example, to enable using the one or more services provided by applications 125, 126 and/or 145.

[00115] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may communicate during a DW according to a contention mechanism. For example, devices 102, 140, 160 and/or 180 may check whether or not a channel may be unoccupied prior to an attempt to transmit a discovery frame during the discovery window.

[00116] In some demonstrative embodiments, a device of devices 102, 140, 160 and/or 180, e.g., device 102, may not transmit the discovery frame during the DW, e.g., if the channel may be occupied. In some demonstrative embodiments, for example, device 102 may transmit the discovery frame during the DW, e.g., if the channel may be unoccupied.

[00117] In some embodiments, the discovery frame may be transmitted as a group addressed, e.g., broadcast or multicast, discovery frame. In other embodiments, the discovery frame may be transmitted as any other type of frame.

[00118] In some demonstrative embodiments, the discovery frame may not require an acknowledgement frame. According to these embodiments, a transmitter of the discovery frame may not backoff a transmission of the discovery frame.

[00119] In some demonstrative embodiments, the discovery frame transmitted by device 102 during the DW may be configured to enable other devices or services that are running on other devices to discover the services on device 102.

[00120] In some demonstrative embodiments, devices of system 100 may utilize availability information, e.g., in the form of an Availability Interval Bitmap and/or Further Availability Map, for example, to allow a device of devices 102, 140, 160 and/or 180, to advertise its availability, for example, in terms of at least one channel and one or more timeslots, during which the device may be available, e.g., active ("awake"), for example, to perform post NAN activities.

[00121] In one example, the availability information may be communicated as part of an Availability Attribute, e.g., including a 32-bit bitmap for 32 timeslots, for example, wherein each timeslot may be 16 milliseconds (ms) long. For example, each bit that may be not zero may represent a timeslot, during which a device sending the Availability Attribute may be to be awake and available to send and/or receive data in a specified method. In another example, the availability information may include any other additional or alternative information, and/or may be communicated and/or formatted in any other manner.

[00122] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may be part of an awareness cluster, e.g., a NAN cluster.

[00123] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may form the NAN cluster.

[00124] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may be configured to communicate according to a Wi-Fi Aware specification and/or any other awareness networking specification, which may be configured to allow a group of devices to discover other devices/services nearby and/or in close proximity, e.g., with low power.

[00125] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may form the NAN cluster and may synchronize to the same clock, e.g., as described above.

[00126] In one example, all devices of the NAN cluster, may converge on a time period and channel, e.g., one or more DWs, to facilitate the discovery of services of devices 102, 140, 160 and/or 180, and/or to achieve low power consumption, e.g., as described above.

[00127] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may be configured to utilize NAN as a power efficient, and/or scalable, peer to peer technology, for example, to enable Wi-Fi devices to discover devices and/or services in their close proximity, and/or to setup one or more data paths with one or more peer devices.

[00128] For example, devices 102, 140, 160 and/or 180 may be configured to form a NAN cluster for devices in proximity, and devices in the same NAN cluster may follow the same awake time schedule, e.g., the same DWs, to facilitate cluster formation and/or achieve low power operation, e.g., as described above.

[00129] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may transmit NAN Service Discovery frames, for example, during the DWs, e.g., to publish services that the devices are interested or provide and/or to subscribe to one or more published services, e.g., as described above.

[00130] In some demonstrative embodiments, two NAN devices may set up a peer to peer NAN Data Path (NDP), for example, over a NAN Data Link (NDL) between the two NAN devices, which may enable to transmit data packets between the two NAN devices. For example, the two NAN devices may setup the NDL and/or NDP, for example, when a desired service is discovered,

[00131] In some demonstrative embodiments, two or more devices, for example, devices 102 and/or 140, may wish to communicate with each other. The two or more devices may establish a Service Data Session (SDS), during which the two devices may set up an NDP and/or an NDL, e.g., to support this SDS or more SDSs.

[00132] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may be configured to perform one or more operations of a procedure, e.g., a data path setup procedure, for setting up a NAN service, e.g., a unicast service or a multicast service.

[00133] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may be configured to perform one or more operations of a procedure, e.g., a NAN data path (NDP) negotiation procedure, for example, to setup a service, for example, to enable data transmission between two NAN devices, for example, NAN2 devices, e.g., between devices 102 and 140.

[00134] In some demonstrative embodiments, simultaneous multi-user (MU) communication, e.g., in accordance with an IEEE 802.1 lax Specification, may be performed, for example, in a time-domain and/or a frequency-domain, e.g., for downlink (DL) and uplink (UL) transmissions.

[00135] In some demonstrative embodiments, an AP may be configured to enable MU communication, e.g., for downlink (DL) and/or uplink (UL) transmissions. For example, a downlink MU transmission may include a MU transmission from the AP to a plurality of station (STAs), and/or an uplink MU transmission may include a MU transmission from the plurality of STAs to the AP, e.g., as described below.

[00136] Reference is made to Fig. 2A, which schematically illustrates a MU-UL transmission from a plurality of STAs 240 to an AP 202, and to Fig. 2B, which schematically illustrates a MU-DL transmission from the AP 202 to the plurality of STAs 240, which may be implemented in accordance with some demonstrative embodiments.

[00137] In some demonstrative embodiments, the MU-UL transmission and/or the MU-DL transmission may include one or more operations and/or communications, for example, in accordance with an IEEE 802.1 lax Specification. [00138] In some demonstrative embodiments, as shown in Fig. 2A, the MU-UL transmission may include a transmission of a trigger frame 212 from AP 202 to the plurality of STAs 240; a transmission of a plurality of UL-MU frames 214 from the plurality of STAs 240 to the AP 202, e.g., in response to trigger frame 212, for example, in accordance with UL resources allocated by the trigger frame 212; and/or a transmission of a plurality of DL-MU acknowledgments (ACKs) 216 from AP 202 to the plurality of STAs 240, e.g., to acknowledge receipt of the plurality of UL-MU frames 214 from the plurality of STAs 240.

[00139] In some demonstrative embodiments, as shown in Fig. 2B, the MU-DL transmission may include a transmission of a plurality of DL-MU frames 218 from AP 202 to the plurality of STAs 240; and/or a transmission of a plurality of UL-MU ACKs 220 from the plurality of STAs 240 to the AP 202, e.g., to acknowledge receipt of the plurality o DL-MU frames 218 from AP 202.

[00140] In some demonstrative embodiments, allocation resources, for example, resources in a time-domain and/or resources in a frequency-domain, may be signaled from the AP 202 to the plurality of STAs 240, for example, to schedule and/or allocate the resources to be used for the MU-communication.

[00141] In some demonstrative embodiments, a STA of the plurality of STAs 240 may be assigned with an identifier to identify the STA, e.g., to uniquely identify the STA to the AP 202, for example, during one or more of the communications of the MU DL transmission and/or the MU UL transmission.

[00142] For example, a STA of the plurality of STAs 240, e.g., each STA of the plurality of STAs 240, may be identified by an Association Identifier (AID), which may be assigned to the STA by the AP, for example, during an association process with the AP.

[00143] In one example, for UL-MU operation, the signaling, e.g., in accordance with an IEEE 802.1 lax Specification, may be included in a trigger frame, e.g., trigger frame 212, for example, such that a STA, e.g., each STA, of the plurality of STAs 240 may be identified by an AID, which may be assigned to the STA by the AP 202, for example, during an association process with the AP 202.

[00144] In another example, for DL MU operation, the signaling e.g., in accordance with an IEEE 802.1 lax Specification, may be included in a High Efficiency (HE) Signal B (HE-SIG-B) field of a Physical (PHY) header of a DL-MU frame, e.g., DL MU frame 218, for example, such that a STA, e.g., each STA, of the plurality of STAs 240 may be identified by an AID assigned to the STA by the AP 202, for example, during an association process with the AP 202. [00145] In some demonstrative embodiments, an AP, e.g., AP 202, may include a NAN STA, and/or one or more STAs of the plurality of STAs 240 may include a NAN STA. For example, device 102 (Fig. 1) may include, operate as, and/or perform one or more functionalities of an AP, e.g., AP 202 including a NAN STA, and/or devices 140, 160 and/or 180 (Fig. 1) may include, operate as, and/or perform one or more functionalities of a STA of STAs 240 including a NAN STA.

[00146] In some demonstrative embodiments, it may be possible that a NAN STA, e.g., a STA implemented by a device of devices 102, 140, 160 and/or 180 (Fig. 1), may be capable of performing MU-communication, e.g., MU-DL and/or MU-UL transmissions. For example, device 102 may include, operate as, and/or perform the functionality of, an AP, which is capable of performing MU-communication, e.g., in accordance with the IEEE 802.1 lax Specification.

[00147] Reference is made to Fig. 3 A, which schematically illustrates a plurality of NAN STAs communicating a MIMO DL transmission, and Fig. 3B, which schematically illustrates the NAN STAs communicating a MU UL transmission, in accordance with some demonstrative embodiments.

[00148] In some demonstrative embodiments, as shown in Fig. 3 A, a NAN STA 302, denoted "NAN0", may be capable of transmitting DL-MU transmissions 310 to a plurality of NAN STAs 340, denoted "NAN1"-"NAN4".

[00149] In some demonstrative embodiments, as shown in Fig. 3B, NAN STA 302 may be capable of receiving UL-MU transmissions 320 from the plurality of NAN STAs 340.

[00150] Referring back to Fig. 1, in some demonstrative embodiments, although a NAN STA, e.g., NAN STA 302 (Fig. 3), may be capable of MU-communication, there may be a need for a technical solution to support MU-communication for NAN STAs, for example, even without an association process between the NAN STAs, e.g., to assign AIDs to the NAN STAs.

[00151] In some demonstrative embodiments, it may be advantageous to implement a solution, which may enable a NAN STA having a capability for MU communication, e.g., a NAN STA implemented by devices 102, 140, 160, and/or 180, to perform MU-communication, which may improve performance of the NAN STAs.

[00152] In one example, it may be advantageous implement a solution to enable MU communication for NAN, for example, even without requiring an association procedure, e.g., for AID assignment. For example, implementing an association procedure in NAN may be complicated. [00153] In some demonstrative embodiments, devices 102, 140, 160, and/or 180 may be configured to utilize one or more NAN signaling mechanisms, for example, to support MU communication between NAN STAs, for example, even without performing an association process between the NAN STAs, e.g., as described below.

[00154] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may be configured to utilize one or more identifiers, for example, NAN identifiers in compliance with a NAN specification, for example, to support MU communication between devices 102, 140, 160 and/or 180, for example, for MU-DL and/or MU-UL transmissions, for example, when devices 102, 140, 160 and/or 180 have a capability of supporting MU-DL and/or MU-UL transmissions, e.g., as described below.

[00155] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may be configured to use a NAN identifier in a STA ID field of a MU frame, for example, a Trigger frame, a DL-MU HE-SIG-A of a DL-MU frame, or a Null-Data Packet Announcement frame, for example, to identify devices 102, 140, 160 and/or 180, for example, for MU communication, e.g., as described below.

[00156] In some demonstrative embodiments, two NAN STAs, e.g., two NAN STAs of devices 102, 140, 160 and/or 180, may establish an NDL schedule, for example, to communicate date between the two NAN STAs, e.g., as described below.

[00170] In some demonstrative embodiments, controller 154 may be configured to control cause, and/or trigger device 140 to establish the NDP over the NDL with device 102. [00171] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may be configured to support signaling of a capability to use NAN identifiers for MU communication. For example, devices 102 and 140 may signal the capability to use NAN identifiers for MU communication, for example, in an NDP setup frame, for example, during setup of the NDP between the devices 102 and 140. In one example, a bit in the NDP setup frame may be set "1" to indicate use of NAN identifiers for MU communication, e.g., instead of AIDs.

[00177] In some demonstrative embodiments, the NDI address may include 48 bits, e.g., as described below. In other embodiments, the NDI address may include any other number of bits.

[00178] In some demonstrative embodiments, one or more of devices 140, 160 and/or 180, e.g., device 140, may receive the MU frame including the information to identify devices 140, 160 and/or 180 for MU communication, e.g., as described below.

[00183] In some demonstrative embodiments, the STA ID field, e.g., in the MU frame announcing the MU UL transmission, may include a first plurality of bits followed by a second plurality of bits, e.g., as described below.

[00184] In some demonstrative embodiments, the first plurality of bits of the STA ID corresponding to device 140 may be based, for example, on an NDL peer ID of the NDL between devices 102 and 140.

[00185] In some demonstrative embodiments, the second plurality of bits of the STA ID corresponding to device 140 may be based, for example, on the NDI address of device 140 for the NDP.

[00190] In some demonstrative embodiments, controller 154 may be configured to control cause, and/or trigger device 140 to transmit an UL frame of the UL transmission, e.g., frame 214 (Fig. 2), to device 102, e.g., in response to the trigger frame or the NDPA frame from device 102.

[00191] In some demonstrative embodiments, device 102 may receive the UL frame of the UL transmission from device 140.

[00192] In some demonstrative embodiments, the UL frame from device 140 to device 102 may include a source address field including a NAN address of device 102, for example, an NDI address of device 102 for the NDP between devices 102 and 140, e.g., as described below.

[00193] In some demonstrative embodiments, controller 124 may be configured to control cause, and/or trigger device 102 to receive from device 140 the UL frame of the UL transmission, e.g., in response to the trigger frame or the NDPA frame from device 102.

[00194] In some demonstrative embodiments, device 102 may trigger a unicast UL transmission, for example, from one device of devices 140, 160 and/or 180, e.g., device 140, e.g., as described below.

[00195] In some demonstrative embodiments, the trigger frame from device 102 may include a unicast trigger frame addressed to device 140, e.g., as described below.

[00196] In some demonstrative embodiments, a receiver address field of the unicast trigger frame may include the NDI address of device 140 for the NDP between devices 102 and 140, e.g., as described below.

[00197] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may be configured to generate, transmit, receive, and/or process a MU uplink announcement, for example, a trigger frame or an NDPA frame, for example, including the plurality of STA IDs of the plurality of STAs to communicate the MU UL transmission, e.g., as described below.

[00198] Reference is made to Fig. 5, which schematically illustrates a structure of a frame 500, in accordance with some demonstrative embodiments. [00199] In one example, device 102 (Fig. 1) may be configured to transmit to a plurality of devices, e.g., devices 140, 160, and/or 180 (Fig. 1) a MU frame, for example, a MU trigger frame or an NDPA frame, including one or more fields of frame 500, e.g., as described below.

[00200] In some demonstrative embodiments, as shown in Fig. 5, frame 500 may include a source address field 512, denoted Transmitter Address ("TA"), which may include a value to identify a transmitter of frame 500.

[00201] In some demonstrative embodiments, device 102 (Fig. 1) may be configured to include in source address field 512 an NDI address of device 102 (Fig. 1).

[00202] In some demonstrative embodiments, as shown in Fig. 5, frame 500 may include a plurality of user information (User Info) fields 514 to identify a respective plurality of STAs.

[00203] In some demonstrative embodiments, as shown in Fig. 5, a user info field 514 may include a STA ID field 515, e.g., an AID12 field, to identify a STA corresponding to the user info field 514.

[00204] In some demonstrative embodiments, as shown in Fig. 5, a STA ID field 516 of a user info field 514 may include 12 bits.

[00205] In some demonstrative embodiments, device 102 (Fig. 1) may be configured to include in STA ID field 516 of a user info field 514 corresponding to device 140 (Fig. 1) a value to identify device 140 (Fig. 1), for example, based on one or more NAN addresses of device 140 (Fig. 1), e.g., as described below.

[00206] In some demonstrative embodiments, device 102 (Fig. 1) may be configured to include in the STA ID field 516 of the user info field 514 corresponding to device 140 (Fig. 1) a value to identify device 140 (Fig. 1), for example, based on an NDI address of device 140 (Fig. 1) for an NDP established between devices 102 and 140 (Fig. 1), e.g., as described below. For example, the NDI address of device 140 (Fig. 1) may include 48 bits, or any other number of bits.

[00207] In some demonstrative embodiments, according to a first option, device 102 (Fig. 1) may be configured to partition the 12 bits of the STA ID field 516 into a first plurality of bits, e.g., 8 bits or any other number of bits, and a second plurality of bits, e.g., 4 bits or any other number of bits.

[00208] In some demonstrative embodiments, device 102 (Fig. 1) may be configured to allocate the 8 bits of STA ID field 516, for example, to include an NDL peer ID, e.g., assigned by device 102 (Fig. 1) to device 140 (Fig. 1). [00209] In some demonstrative embodiments, device 102 (Fig. 1) may be configured to allocate the 4 bits of STA ID field 516, for example, to a hashed value the NDI address, of device 140 (Fig. 1).

[00210] In some demonstrative embodiments, according to a second option, device 102 (Fig. 1) may be configured to include in the 12 bits of the STA ID field 516 a hashed value of the NDI address of device 140 (Fig. 1) for an NDP established with device 102 (Fig. 1).

[00211] In one example, in some cases, assigning the 12 bits of the STA ID field 516 with the hashed value of the NDI address, e.g., without including information on the NDL ID, may not guarantee that only one peer device with an established NDL with device 102 (Fig. 1) is to respond on one allocated frequency resource.

[00212] In some demonstrative embodiments, the hash value of the NDI address may be based on a predefined hash function.

[00213] In other embodiments, any other configuration and/or values may be applied to the STA ID field to identify device 140 (Fig. 1).

[00214] In some demonstrative embodiments, as shown in Fig. 5, frame 500 may include a receiver address (RA) field 518, which may identify a device to receive frame 500, for example, if frame 500 includes a unicast trigger frame.

[00215] In some demonstrative embodiments, according to a second option, device 102 (Fig. 1) may be configured to include in RA filed 518 one of the NDI addresses of device 140 (Fig. 1), for example, if frame 500 includes a unicast Trigger frame addressed to device 140 (Fig. 1).

[00216] In some demonstrative embodiments, including an NDI of a transmitter STA, e.g., device 102 (Fig. 1), in field 518 may be unique for a receiver STA, e.g., device 140 (Fig. 1), to identify the transmitter of frame 500 from an established NDP.

[00217] In some demonstrative embodiments, including the NDL peer ID in STA ID field 516 may be useful, e.g., in addition to an NDI address, for example, if two peer NAN STAs with an established NDP have a same hashed value of the NDI address.

[00218] In some demonstrative embodiments, a NAN STA, e.g., device 102 (Fig. 1), may be configured to guarantee a different NDL peer ID to be assigned for peer devices with an established NDL.

[00219] In some demonstrative embodiments, including the hashed value of the NDI address of a receiver STA, e.g., device 140 (Fig. 1), in the STA ID filed 516 may be useful, for example, for the receiver STA to identify data for a specific NDP, for example, if a plurality of NDPs are established between NAN STAs over a same NDI. For example, a hashed value of the NDI address NDI 2.1 of an NDI 417 (Fig. 4) of device 140 (Fig. 1) may be useful for device 140 (Fig. 1), for example, to identify data for a specific NDP of the plurality of NDPs 412 (Fig. 4).

[00220] In some demonstrative embodiments, for example, when a first NAN STA, e.g., device 102 (Fig. 1), establishes an NDP with a second NAN STA, e.g., device 140 (Fig. 1), the first NAN STA may make sure that an assigned NDI for an NDP does not have the same hashed value, e.g., as a previously assigned NDI.

[00221] Referring back to Fig. 1, in some demonstrative embodiments, a STA, e.g., an AP, for example, device 102, may be configured to transmit to a plurality of STAs, e.g., devices 140, 160 and/or 180, a MU frame, which may include a DL-MU PPDU of a MU-DL transmission, for example, from device 102 to the plurality of STAs, e.g., devices 140, 160 and/or 180.

[00222] In some demonstrative embodiments, the DL-MU PPDU may include a High Efficiency (HE) PPDU, or any other PPDU.

[00223] In some demonstrative embodiments, the DL-MU PPDU may include a preamble including a plurality of STA ID fields or the plurality of STAs to receive the DL-MU PPDU, e.g., as described below.

[00224] In some demonstrative embodiments, the HE PPDU may include a Signal B (SIG-B) field including the plurality of TA ID fields. In other embodiments, the plurality of STA IDs may be included in any other field.

[00225] In some demonstrative embodiments, a STA ID field of the plurality of STA ID fields in the DL-MU PPDU may include 11 bits. In other embodiments, the STA ID field may include any other number of bits.

[00226] In some demonstrative embodiments, the plurality of the bits of the STA ID field may be partitioned into a first plurality of bits followed by a second plurality of bits, e.g., as described below.

[00227] In some demonstrative embodiments, the first plurality of bits of the STA ID corresponding to device 140 may be based, for example, on an NDL peer ID of the NDL between devices 102 and 140.

[00228] In some demonstrative embodiments, the second plurality of bits of the STA ID corresponding to device 140 may be based, for example, on the NDI address of device 140 for the NDP. [00229] In some demonstrative embodiments, the first plurality of bits may include 8 bits, and the second plurality of bits may include 3 bits. In other embodiments, any other partition of the bits of the STA ID field may be applied.

[00230] In some demonstrative embodiments, the second plurality of bits of the STA ID corresponding to device 140 may include a hashed value of the NDI address of device 140 for the NDP.

[00231] In some demonstrative embodiments, the DL-MU PPDU may include a Basic Service Set (BSS) color field including a BSS value, for example, to identify a group of devices, for example, including devices 140, 160 and/or 180, e.g., as described below.

[00232] In some demonstrative embodiments, the BSS color field may include 6 bits. In other embodiments, the BSS color field may include any other number of bits.

[00233] In some demonstrative embodiments, device 102 may be configured to determine the BSS value based, for example, on a NAN Data Cluster (NDC) Identifier (NDC-ID) of an NDC including the NDL between devices 102 and 140.

[00234] In some demonstrative embodiments, device 102 may be configured to set the BSS value based, for example, on a NAN cluster ID of a NAN cluster including device 102.

[00235] In some demonstrative embodiments, device 102 may be configured to set the BSS value to include a value of zero.

[00236] In some demonstrative embodiments, the plurality of STA, e.g., devices 140, 160 and/or 180, may receive from device 102 the downlink DL-MU PPDU including the BSS color field and/or the STA ID fields to identify devices 140, 160 and/or 180 for the UL transmission.

[00237] In some demonstrative embodiments, device 140 may receive from device 102 the downlink DL-MU PPDU including the BSS color field and/or the STA ID field.

[00238] In some demonstrative embodiments, controller 154 may be configured to control cause, and/or trigger device 140 to transmit an UL-MU Ack to device 102, for example, to acknowledge receipt of the DL-MU PPDU from device 102.

[00239] In some demonstrative embodiments, device 102 may receive the UL-MU Ack from device 140.

[00240] In some demonstrative embodiments, controller 124 may be configured to control cause, and/or trigger device 102 to receive the UL-MU Ack frame from device 140, e.g., to acknowledge receipt of the DL-MU PPDU. [00241] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may be configured to generate, transmit, receive, and/or process a DL-MU PPDU, for example, including the plurality of STA IDs of the plurality of STAs to receive the DL-MU PPDU transmission, and/or the BSS color field, e.g., as described below.

[00242] In some demonstrative embodiments, the STA ID field, for example, when included in an HE-SIG-B preamble, may include 11 bits.

[00243] In some demonstrative embodiments, device 102 may be configured to include in the STA ID field corresponding to device 140 in the DL-MU PPDU a value to identify device 140, for example, based on one or more NAN addresses of device 140, e.g., as described below.

[00244] In some demonstrative embodiments, device 102 may be configured to include in the STA ID field corresponding to device 140 in the DL-MU PPDU a value to identify device 140, for example, based on an NDI address of device 140 for an NDP established between devices 102 and 140, e.g., as described below. For example, the NDI address of device 140 may include 48 bits, or any other number of bits.

[00245] In some demonstrative embodiments, according to a first option, device 102 may be configured to partition the 11 bits of the STA ID field into a first plurality of bits, e.g., 8 bits or any other number of bits, and a second plurality of bits, e.g., 3 bits or any other number of bits.

[00246] In some demonstrative embodiments, device 102 may be configured to allocate the 8 bits of STA ID field, for example, to include an NDL peer ID, e.g., assigned by device 102 to device 140.

[00247] In some demonstrative embodiments, device 102 may be configured to allocate the 3 bits of STA ID field, for example, to a hashed value the NDI address, of device 140.

[00248] In some demonstrative embodiments, according to a second option, device 102 may be configured to include in the 11 bits of the STA ID field a hashed value of the NDI address of device 140 for an NDP established with device 102.

[00249] In some demonstrative embodiments, the hash value of the NDI address may be based on a predefined hash function.

[00250] In other embodiments, any other configuration and/or values may be applied to the STA ID field to identify device 140.

[00251] In some demonstrative embodiments, the BSS color field of, for example, when included in an HE-SIG-A preamble, may include 6 bits. [00252] In some demonstrative embodiments, according to a first option, device 102 may be configured to include in the 6 bits of the BSS color field of the DL-MU PPDU a hashed value of an NDC-ID of a NAN data cluster including the NDL between devices 102 and 140.

[00253] In some demonstrative embodiments, the NDC ID may include 48 bits, or any other number of bits.

[00254] In one example, each NDL may belong to one NDC.

[00255] In some demonstrative embodiments, according to a second option, device 102 may be configured to include in the 6 bits of the BSS color field of the DL-MU PPDU a hashed value of the NAN Cluster ID, which may be 48 bits, of a NAN cluster including device 102.

[00256] In some demonstrative embodiments, according to a third option, device 102 may be configured to set the BSS color field of the DL-MU PPDU to a value set to zero.

[00257] In other embodiments, any other configuration and/or values may be applied to the BSS color field.

[00258] In some demonstrative embodiments, the BSS color may be included, for example, in an HE Single User (SU) PPDU, an HE extended range SU PPDU, an HE trigger-based PPDU, and/or any other PPDU.

[00259] In some demonstrative embodiments, a DL-MU PPDU may not include a source address field. Accordingly, it may be possible that a STA receiving the DL-MU PPDU ("receiver STA") may not be the intended receiver of the DL-MU PPDU, and may decode some Resource Units (RU) of the DL-MU PPDU. However, a data frame of the DL-MU PPDU, may include RA and/or TA fields, and if the receiver STA finds that an address in the TA is not equal to any one of the NDIs from a peer device with an identified NDL, and/or an address in the RA field is not equal to any address of the NDIs assigned by the receiver STA, the receiver STA may simply drop the DL-MU PPDU and stop decoding the DL-MU PPDU.

[00260] In some demonstrative embodiments, including the hashed value of the NDC-ID or the cluster ID, e.g., in the BSS color field, may be useful, for example, to allow a NAN STA, for example, to avoid decoding every received DL MU transmission.

[00261] In some demonstrative embodiments, including an allocation of NDL peer ID, for example, in the DL MU PPDU, may be useful, for example, to reduce a probability for a NAN STA to decode a following data pay load, e.g., in a DL-MU PPDU, which is not intended for the NAN STA. [00262] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may be part of a NAN Multicast Service Group (NMSG), e.g., as described below.

[00263] In some demonstrative embodiments, a first device of the NMSG, e.g., device 102, may be configured to communicate a multicast transmission with other devices of the NMSG, for example, including device 140, e.g., as described below

[00264] In some demonstrative embodiments, controller 154 may be configured to control cause, and/or trigger device 140 to communicate with devices of the NMSG.

[00265] In some demonstrative embodiments, controller 124 may be configured to control cause, and/or trigger device 102 to communicate with devices of the NMSG.
