[0068] In some demonstrative embodiments, devices 102 and/or 140 may be configured to perform the functionality of a non-AP STA, e.g., a DMG non-AP STA, and/or a non-PCP STA, e.g., a DMG non-PCP STA, for example, a non-AP/PCP STA, e.g., a DMG non-AP/PCP STA.

[0069] In one example, a station (STA) may include a logical entity that is a singly addressable instance of a medium access control (MAC) and physical layer (PHY) interface to the wireless medium (WM). The STA may perform any other additional or alternative functionality.

[0070] In one example, an AP may include an entity that contains a station (STA), e.g., one STA, and provides access to distribution services, via the wireless medium (WM) for associated STAs. The AP may perform any other additional or alternative functionality.

[0071] In one example, a personal basic service set (PBSS) control point (PCP) may include an entity that contains a STA, e.g., one station (STA), and coordinates access to the wireless medium (WM) by STAs that are members of a PBSS. The PCP may perform any other additional or alternative functionality.

[0072] In one example, a PBSS may include a directional multi-gigabit (DMG) basic service set (BSS) that includes, for example, one PBSS control point (PCP). For example, access to a distribution system (DS) may not be present, but, for example, an intra-PBSS forwarding service may optionally be present.

[0073] In one example, a PCP/AP STA may include a station (STA) that is at least one of a PCP or an AP. The PCP/AP STA may perform any other additional or alternative functionality.

[0074] In one example, a non-AP STA may include a STA that is not contained within an AP. The non-AP STA may perform any other additional or alternative functionality.

[0075] In one example, a non-PCP STA may include a STA that is not a PCP. The non-PCP STA may perform any other additional or alternative functionality.

[0076] In one example, a non PCP/AP STA may include a STA that is not a PCP and that is not an AP. The non-PCP/ AP STA may perform any other additional or alternative functionality.

[0077] In some demonstrative embodiments, devices 102 and 140 may be configured to perform operations of dynamical scheduling and/or allocation, e.g., as described below.

[0078] In some demonstrative embodiments, devices 102 and/or 140 may be configured to perform dynamic allocation of a service period (SP), for example, to provide a solution to allocate channel time during scheduled service periods (SPs), during different types of contention based access periods (CBAPs), and/or any other periods. [0079] In some demonstrative embodiments, dynamic scheduling of an allocated time may be provided to a station, for example, using a grant frame, e.g., as described below.

[0080] In some demonstrative embodiments, controller 124 may cause radio 114 to generate, process and/or transmit a grant frame, e.g., to device 140 and/or to one or more other devices, for example, to dynamically allocate a time period, e.g., to device 140 and/or to one or more other devices, e.g., as described below.

[0081] In some demonstrative embodiments, radio 144 may receive the grant frame, and controller 154 may process the grant frame, and may perform one or more operations according to the contents of the grant frame. For example, controller 154 may control communications by device 140 according to the allocated time period allocated by the grant frame. In one example, controller 154 may cause device 140 to communicate during the allocated time period, for example, if the allocated time period is to be allocated for communications by device 140, e.g., as described below.

[0082] In some demonstrative embodiments, the grant frame may be generated and/or transmitted by an AP, a PCP, an AP/PCP STA, a non-AP STA, a non-PCP STA, and/or a non- AP/PCP STA.

[0083] In some demonstrative embodiments, the grant frame may be addressed to, received by, and/or processed by, an AP, a PCP, an AP/PCP STA, a non-AP STA, a non-PCP STA, and/or a non- AP/PCP STA.

[0084] In some demonstrative embodiments, the Grant frame may include fields and/or subfields, which may be configured for time allocation and/or scheduling purposes.

[0085] In one example, configuring fields and/or subfields of a grant frame according to a conventional grant frame format, for example, a grant frame format in accordance with an IEEE 802.11 Standard, for example, IEEE 802.11ad-2012 ("IEEE P802.1 lad-2012, IEEE Standard or Information Technology - Telecommunications and Information Exchange Between Systems - Local and Metropolitan Area Networks - Specific Requirements - Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications - Amendment 3: Enhancements for Very High Throughput in the 60GHz Band", 28 December, 2012), may not be applicable, efficient and/or sufficient, for example, to cover all cases and/or scenarios the grant frame may be used for.

[0086] In one example, configuring fields and/or subfields of a grant frame according to a conventional grant frame format, for example, a grant frame format in accordance with IEEE 802.1 lad-2012, may not be sufficient and/or efficient to enable using the grant frame, for example, when exchanging the grant frame between peer stations ("peers") in condition of multiple accesses, e.g., during a Contention based Access Period (CBAP). No solution is known to enable such an exchange, e.g., in accordance with the frame format defined by IEEE 802.11ad-2012. This is only one example, and there may be additional scenarios and/or use cases, in which the conventional format of the grant frame may not be applicable, sufficient and/or efficient.

[0087] In some demonstrative embodiments, a field in the grant frame, for example, a field of an allocation duration or any other field in the grant frame, may be defined and/or used, for example, depending on one or more attributes of a scheduling to be performed by the grant frame, e.g., as described below.

[0088] In some demonstrative embodiments, a field in the grant frame, for example, a field of an allocation duration or any other field in the grant frame, may be defined and/or used, for example, depending on whether the grant frame is to be used for scheduling purposes by an AP STA or PCP STA, or whether the grant frame is to be used to communicate in advance access between peers, for example, non-AP/PCP STAs, e.g., as described below.

[0089] In some demonstrative embodiments, a device transmitting the grant frame, e.g., device 102, may be configured to indicate a use of the allocation duration field in the grant frame, for example, to a receiver of the grant frame, e.g., device 140, as described below.

[0090] In one example, the device transmitting the grant frame, e.g., device 102, may be configured to indicate the use of the allocation duration field in the grant frame, for example, in a manner, which may enable a stateless interpretation of the field, e.g., by the receiver of the grant frame.

[0091] Some demonstrative embodiments may be implemented, for example, to allow using the same format of the grant frame, for example, even with respect to different types of access allocations, and/or may allow delivering information relevant for a specific access type, for example, a service period, an allocated CBAP, a "CBAP only" allocation, and/or any other access period, e.g., even if not supported by a conventional solution.

[0092] Fig. 2 is a schematic illustration of a grant frame 200, in accordance with some demonstrative embodiments.

[0093] In some demonstrative embodiments, the grant frame 200 may be transmitted by a device, e.g., device 102 (Fig. 1), and received by a device, e.g., device 140 (Fig. 1).

[0094] In some demonstrative embodiments, grant frame 200 may include a Frame Control (FC) field 202, for example, including 2 octets, e.g., 16 bits. [0095] In some demonstrative embodiments, grant frame 200 may include a Duration/ID field 204, for example, following FC field 202, and including, for example, 2 octets, e.g., 16 bits.

[0096] In some demonstrative embodiments, Duration/ID field 204 may include a duration value, e.g., as described below.

[0097] In some demonstrative embodiments, grant frame 200 may include a Receive Address (RA) field 206, for example, following duration field 204, and including, for example, 6 octets, e.g., 48 bits. In one example RA field 206 may include, for example, an address, e.g., a Media Access Control (MAC) address, of a STA to receive grant frame 200.

[0098] In some demonstrative embodiments, grant frame 200 may include a Transmit Address (TA) field 208, for example, following RA field 206, and including, for example, 6 octets, e.g., 48 bits. In one example TA field 208 may include, for example, an address, e.g., a MAC address, of a STA to transmit grant frame 200.

[0099] In some demonstrative embodiments, grant frame 200 may include a Dynamic Allocation Info field 210, for example, following TA field 208, and including, for example, 5 octets, e.g., 40 bits.

[00100] In some demonstrative embodiments, grant frame 200 may include a Beamforming (BF) control field 212, for example, following Dynamic Allocation Info field 210, and including, for example, 2 octets, e.g., 16 bits.

[00101] In some demonstrative embodiments, grant frame 200 may include a Frame Check Sequence (FCS) field 214, for example, following BF control field 212, and including, for example, 4 octets, e.g., 32 bits.

[00102] Fig. 3 is a schematic illustration of a dynamic allocation information field 300, in accordance with some demonstrative embodiments. For example, the grant frame 200 of Fig. 2 may include the dynamic allocation information field 300 of Fig. 3.

[00103] In some demonstrative embodiments, dynamic allocation information field 300 may include a Traffic Identifier (TID) subfield 302, e.g., including 4 bits.

[00104] In some demonstrative embodiments, dynamic allocation information field 300 may include an Allocation type subfield 304, for example, following TID subfield 302, and including, for example, 3 bits.

[00105] In some demonstrative embodiments, dynamic allocation information field 300 may include a Source Association Identifier (AID) subfield 306, for example, following Allocation type subfield 304, and including, for example, 8 bits. [00106] In some demonstrative embodiments, dynamic allocation information field 300 may include a Destination AID subfield 308, for example, following Source AID subfield 306, and including, for example, 8 bits.

[00107] In some demonstrative embodiments, dynamic allocation information field 300 may include an allocation duration subfield 310, for example, following Destination AID subfield 308, and including, for example, 16 bits.

[00108] In some demonstrative embodiments, dynamic allocation information field 300 may include an access mode indication subfield 314, which may be configured, for example, to indicate an access mode of an allocation according to a grant frame, e.g., grant frame 200 (Fig. 2), which includes dynamic allocation information field 300, e.g., as described below.

[00109] In some demonstrative embodiments, as shown in Fig. 3, access mode subfield 314 may have a size of one bit.

[00110] In some demonstrative embodiments, as shown in Fig. 3, access mode subfield 314 may be included as part of, or instead of, a reserved subfield 312 of dynamic allocation information field 300. In other embodiments, access mode subfield 314 may be included in the form of, as part of, or instead of, any other subfield of dynamic allocation information field 300.

[00111] In some demonstrative embodiments, some settings of the fields and/or subfields of the grant frame, for example, in accordance with an IEEE 802.11 Standard, e.g., according to IEEE 802.1 lad-2012, may be suitable for only some scenarios. For example, in one scenario, the Allocation Duration subfield 310 of the Dynamic Allocation Info field 300 may be set to include a granted duration of a SP or CBAP allocation, e.g., in microseconds, and duration field 214 (Fig. 2) of the Grant frame 200 (Fig. 2) may be defined to cover a time to transmit remaining Grant frame(s), if required, a related inter frame spacing (IFS), and the Allocation Duration carried in the Dynamic Allocation Info field 210 (Fig. 2).

[00112] For example, such settings may be best suited, for example, to a specific scenario of delivering SP and/or CBAP allocations, for example, by an AP STA or a PCP STA, for example, to one or more non-AP and/or non-PCP STAs.

[00113] In some demonstrative embodiments, devices 102 and/or 140 (Fig. 1) may be configured to be able to use the grant frame 200 (Fig. 2) and/or dynamic allocation information field 300 with respect to one or more additional or alternative implementations, situations, procedures, operations, and/or scenarios, which may not be limited to only this specific scenario. [00114] In some demonstrative embodiments, devices 102 and/or 140 (Fig. 1) may be configured to use one or more fields and/or subfields of the grant frame 200 (Fig. 2) and/or dynamic allocation information field 300, for example, to allocate and/or schedule one or more additional and/or alternative types of access periods, and/or to enable using the grant frame 200 (Fig. 1) by one or more other types of devices and/or stations, and/or for one or more other purposes, use cases, and/or scenarios, e.g., as described below.

[00115] In some demonstrative embodiments, a transmitter of grant frame 200 (Fig. 2), e.g., device 102 (Fig. 1), may be configured to generate and/or set access mode subfield 314 to encode an indication of one or more conditions to interpret the one or more fields of grant frame 200 (Fig. 2), e.g., duration field 204 (Fig. 2), and/or one or more subfields of dynamic allocation information field 300, e.g., allocation duration subfield 310, e.g., as described below.

[00116] In some demonstrative embodiments, a subfield of the dynamic allocation info field 300, for example, the reserved subfield 312, may be configured to include access mode subfield 314, for example, to encode an indication of one or more conditions to interpret the Allocation Duration subfield 310, e.g., as described below.

[00117] In other embodiments, devices 102 and/or 140 (Fig. 1) may use any other subfield of the dynamic allocation info field 300 to encode an indication of one or more conditions to interpret the allocation duration subfield 310. In one example, a new, e.g., additional, subfield may be added to the dynamic allocation info field 300, for example, subsequent to the allocation duration subfield 310, or in any other location.

[00118] Referring back to Fig. 1, in some demonstrative embodiments, a device, e.g., device 102 (Fig. 1), transmitting a grant frame, e.g., the grant frame 200 (Fig. 2), may be configured to set a value of the access mode subfield of the dynamic allocation info field 300 (Fig. 3), e.g., access mode subfield 314 (Fig. 3), to indicate how one or more subfields of the grant frame are to be interpreted and/or used, e.g., as described below.

[00119] In some demonstrative embodiments, a device receiving the grant frame, e.g., device 140 (Fig. 1), may be configured to process the value of the access mode subfield of the dynamic allocation info field, e.g., access mode subfield 314 (Fig. 3), for example, to determine the access mode and/or type to be allocated and/or scheduled by the grant frame, e.g., as described below.

[00120] In some demonstrative embodiments, controller 124 may be configured to cause a wireless station, for example, a wireless station implemented by device 102, to generate a grant frame, for example, grant frame 200 (Fig. 2), including a duration field, e.g., duration field 204 (Fig. 2), and a dynamic allocation info field, e.g., dynamic allocation info field 210 (Fig. 2). [00121] In some demonstrative embodiments, controller 124 may be configured to cause a wireless station to generate the dynamic allocation info field, e.g., dynamic allocation info field 300 (Fig. 3), including an allocation duration subfield, e.g., allocation duration subfield 310 (Fig. 3), and an access mode subfield, e.g., access mode subfield 314 (Fig. 3).

[00122] In some demonstrative embodiments, controller 124 may be configured to cause the wireless station to generate the access mode subfield, e.g., access mode subfield 314, to indicate an access mode of an allocation according to the grant frame, for example, an access mode to be allocated by grant frame 200 (Fig. 2), e.g., as described below.

[00123] In some demonstrative embodiments, controller 124 may be configured to cause the wireless station to transmit the grant frame. For example, controller 124 may cause radio 114 to process transmission the grant frame 200 (Fig. 2).

[00124] In some demonstrative embodiments, controller 124 may be configured to cause the wireless station to transmit the grant frame, e.g., grant frame 200 (Fig. 2), including dynamic allocation info subfield 300 (Fig. 3), which includes access mode subfield 314 (Fig. 3), for example, as a non-AP/PCP station (STA).

[00125] In some demonstrative embodiments, controller 124 may be configured to cause the wireless station to transmit the grant frame, e.g., grant frame 200 (Fig. 2), including dynamic allocation info subfield 300 (Fig. 3), which includes access mode subfield 314 (Fig. 3), for example, as an AP/PCP station (STA).

[00126] In other embodiments, controller 124 may be configured to cause the wireless station to transmit the grant frame, e.g., grant frame 200 (Fig. 2), including dynamic allocation info subfield 300 (Fig. 3), which includes access mode subfield 314 (Fig. 3), for example, as any other DMG STA or any other STA.

[00127] In some demonstrative embodiments, controller 124 may be configured to cause the wireless station to transmit the grant frame, e.g., grant frame 200 (Fig. 2), including dynamic allocation info subfield 300 (Fig. 3), which includes access mode subfield 314 (Fig. 3), for example, during a Contention-Based Access period (CBAP).

[00128] In other embodiments, controller 124 may be configured to cause the wireless station to transmit the grant frame, e.g., grant frame 200 (Fig. 2), including dynamic allocation info subfield 300 (Fig. 3), which includes access mode subfield 314 (Fig. 3), for example, during any other allocation, period, and/or mode.

[00129] In some demonstrative embodiments, controller 124 may be configured to cause the wireless station to set the access mode subfield, e.g., access mode subfield 314 (Fig. 3), to a predefined value, which may be configured to indicate that the grant frame is to indicate a time of an attempt to obtain a future TxOP, for example, between a first STA and a second STA. The first STA may include a STA transmitting the grant frame, for example, a STA having an address indicated by TA field 208 (Fig. 2), e.g., the STA implemented by device 102; and/or the second STA may include, for example, a STA having an address indicated by the RA field 206 (Fig. 2), e.g., the STA implemented by device 140.

[00130] In some demonstrative embodiments, controller 124 may be configured to cause the wireless station to set the access mode subfield, e.g., access mode subfield 314 (Fig. 3), to a predefined value, which may be configured to indicate that a start time of an attempt to obtain a TxOP is to be determined based on a sum of a value in the allocation duration subfield, e.g., allocation duration subfield 310 (Fig. 3), and a value in the duration field, e.g., duration field 214 (Fig. 2).

[00131] In some demonstrative embodiments, the predefined value may be "1". For example, controller 124 may be configured to cause the wireless station to set the access mode subfield, e.g., access mode subfield 314 (Fig. 3), to the value of "1", to indicate that a start time of an attempt to obtain a TxOP is to be determined based on a sum of a value in the allocation duration subfield, e.g., allocation duration subfield 310 (Fig. 3), and a value in the duration field, e.g., duration field 214 (Fig. 2).

[00132] In some demonstrative embodiments, the start time of the attempt to obtain the TxOP may be determined, for example, based on the sum of the value in allocation duration subfield 310 (Fig. 3), and the value in duration field 214 (Fig. 2), and based on a Physical Layer (PHY) Transmit end (PHY.TXEND) indication, e.g., as described below.

[00133] In some demonstrative embodiments, controller 124 may be configured to cause the wireless station to generate and/or set the access mode subfield 314 (Fig. 3), for example, as follows:

Table 1 - Access Mode

[00134] In some demonstrative embodiments, controller 124 may be configured to cause the wireless station to generate and/or set the access mode subfield 314 (Fig. 3), for example, to indicate a use of the allocation duration subfield 310 (Fig. 3), for example, as described below. In other embodiments, any additional or alternative use may be defined.

[00135] In some demonstrative embodiments, when the Dynamic Allocation Info subfield is transmitted within a Grant frame with the access mode subfield equal to 0, for example, by an AP or PCP STA, e.g., during a Grant period (GP) and/or an announcement transmission interval (ATI), the Allocation Duration subfield may contain the granted duration of SP or CBAP allocations.

[00137] According to these embodiments, controller 124 may be configured to cause the wireless station implemented by device 102 to set the allocation duration subfield 310 (Fig. 3) to include a value representing the granted duration of the SP or CBAP allocation.

[00138] According to these embodiments, controller 124 may be configured to cause the wireless station implemented by device 102 to set access mode subfield 314 (Fig. 3), for example, to the value of "0", e.g., to indicate that the allocation duration subfield 310 (Fig. 3) is to include the granted duration of the SP or CBAP allocation.

[00139] In some demonstrative embodiments, the Dynamic Allocation Info subfield may be transmitted within a Grant frame with the Access Mode subfield equal to 1, for example, by a STA, e.g., to indicate a time the STA is attempting to obtain a Transmit Opportunity (TXOP). According to these embodiments, e.g., when the Access Mode subfield equal to 1, the sum of the value in the Allocation Duration field plus a value in the Duration field of the grant frame, may indicate the time, for example, in relation to a PHY-TXEND.indication primitive of the Grant frame.

[00140] In some demonstrative embodiments, controller 124 may be configured to cause the wireless station implemented by device 102 to perform the functionality of a STA, e.g., a PCP/AP STA or a non-PCP/AP STA; and to generate and transmit a grant frame 200 (Fig. 2), for example, to indicate a start time of an attempt to obtain a TxOP.

[00142] According to these embodiments, controller 124 may be configured to cause the wireless station implemented by device 102 to set access mode subfield 314 (Fig. 3), for example, to the value of "1", e.g., to indicate that the start time of the attempt to obtain the TxOP, for example, in relation to the PHY-TXEND.indication primitive of the grant frame 200 (Fig. 2), is to be determined, for example, based on the sum of the value in the allocation duration subfield 310 (Fig. 3) and the value in the duration field 214 (Fig. 2).

[00143] In some demonstrative embodiments, controller 154 may be configured to cause a wireless station, for example, a wireless station implemented by device 140, to process reception of a grant frame ("the received grant frame"). For example, controller 154 may cause radio 144 and/or message processor 158 to process reception of the frame.

[00144] In one example, the received grant frame may include the frame transmitted by device 102.

[00145] In some demonstrative embodiments, controller 154 may be configured to cause a wireless station, for example, a wireless station implemented by device 140, to process reception of a received grant frame, for example, grant frame 200 (Fig. 2), including a duration field, e.g., duration field 204 (Fig. 2), and a Dynamic Allocation Info field, e.g., dynamic allocation info field 210 (Fig. 2).

[00149] In other embodiments, controller 154 may be configured to cause the wireless station to process the received grant frame, e.g., grant frame 200 (Fig. 2), including dynamic allocation info subfield 300 (Fig. 3), which includes access mode subfield 314 (Fig. 3), for example, as any other DMG STA or any other STA.

[00150] In some demonstrative embodiments, controller 154 may be configured to cause the wireless station to process the received grant frame, e.g., grant frame 200 (Fig. 2), including dynamic allocation info subfield 300 (Fig. 3), which includes access mode subfield 314 (Fig. 3), for example, during a Contention-Based Access period (CBAP).

[00151] In other embodiments, controller 154 may be configured to cause the wireless station to process the received grant frame, e.g., grant frame 200 (Fig. 2), including dynamic allocation info subfield 300 (Fig. 3), which includes access mode subfield 314 (Fig. 3), for example, during any other allocation, period, and/or mode.

[00152] In some demonstrative embodiments, controller 154 may be configured to cause the wireless station to process the access mode subfield, e.g., access mode subfield 314 (Fig. 3), to determine an access mode of an allocation according to the grant frame, for example, an access mode to be allocated and/or scheduled by grant frame 200 (Fig. 2), e.g., as described above.

[00153] In some demonstrative embodiments, controller 154 may be configured to cause the wireless station to operate according to the access mode indicated by the access mode subfield.

[00154] In some demonstrative embodiments, controller 154 may be configured to cause the wireless station to determine a start time of an attempt to obtain a TxOP, for example, when the access mode subfield, e.g., access mode subfield 314 (Fig. 3), includes a predefined value, e.g., the value "1".
