In some examples, the device includes, among other possible circuitry, components, elements, etc., a communication interface and circuitry for processing to facilitate communication with one or more other WDEV (s) and to generate signals for such communication to process. The WDEV generates a first Orthogonal Frequency Division Multiple Access (OFDMA) frame that provides information regarding additional resource units (RUs) to be used by other WDEVs. The WDEV transmits the first OFDMA frame to additional WDEVs and receives a second OFDMA frame from the WDEVs based on some RUs specified within the first OFDMA frame. The WDEV then generates and transmits a third OFDMA frame to the further WDEVs (eg, based on one or more RUs extending over one or more RUs within which the information in the second OFDMA Frames are received.

At a first time or during a first period (for example, period 1 (ΔT1)), the WDEV transmits 310 one or more signal (s) to the WDEV 390 , and / or the WDEV 390 transmits one or more additional signals to the WDEV 310 , At a second time or during a second period (for example, period 2 (ΔT2)), the WDEV processes 310 one or more of the WDEV 390 received signal (s), and / or the WDEV 390 processes one or more of the WDEV 310 received signals.

In some examples, the types of signals, frames, etc. included between the WDEV 310 and the WDEVs 390 to 391 one or more trigger frame (s) (M-BAs), such as an uplink (UL) Multiple User (MU) PLCP Protocol Data Unit (PPDU) ( where PLCP corresponds to the physical layer convergence procedure) used by the WDEVs 3901 to 390 in response to an earlier downlink signal (DL signal), an earlier downlink frame (DL frame), etc. transmitted from the WDEV 310 to the WDEVs 390 to 391 was transferred.

In an example of operation and implementation, WDEV supports 310 the communication with the WDEVs 130 . 132 , The WDEV 310 is configured to generate a trigger frame (which may be, for example, an OFDMA frame) that specifies certain information. In some examples, the trigger frame indicates the first plurality of resource units (RUs) that are used by the WDEVs 390 to 391 are to be used when transmitting a second OFDMA frame to the wireless communication device, and also a second plurality of RUs, within which the WDEVs 390 to 391 to receive a third OFDMA frame from the wireless communication device.

It should be noted that the second OFDMA frame according to the OFDMA signaling first information from the WDEV 390 and second information from the WDEV 391 may include. The WDEV 310 is then configured to generate an M-BA (which may also be an OFDMA frame) based on receipt of the second UL-MU-PPDU. The WDEV 310 is then configured to apply the M-BA to the WDEVs based on the second plurality of RUs specified within the trigger frame 390 to 391 transfers.

In another example of operation and implementation, WDEV supports 310 the communication with the WDEVs 130 . 132 , The WDEV 310 is configured to generate a trigger frame (which may be, for example, an OFDMA frame) that specifies certain information. In some examples, the trigger frame indicates a first plurality of Resource Units (RUs) to be retrieved from the WDEVs 390 to 391 are to be used when transmitting a second OFDMA frame to the wireless communication device.

Then the WDEV 310 then configured to send the trigger frame to the WDEVs 390 to 391 transfers. The WDEV 310 is then configured to derive from the WDEVs based on the first plurality of RUs specified within the trigger frame 390 to 391 receives a UL-MU-PPDU (which, for example, may also be an OFDMA frame). It should be noted that the second OFDMA frame according to the OFDMA signaling first information from the WDEV 390 and second information from the WDEV 391 may include. The WDEV 310 is then configured to generate an M-BA (which may also be an OFDMA frame) based on receipt of the second UL-MU-PPDU. The WDEV 310 is then configured to call the M-BA based on a second plurality of RUs that are in a section of the M-BA. BA before the respective actual confirmation (s) (ACK (s)) within the M-BA, to the WDEVs 390 to 391 transfers. For example, the second plurality of RUs may be specified within one or more signal fields (SIGs) within the M-BA that precede the actual respective ACK (s) within the M-BA. With regard to this example of operation and implementation, it is noted that the information that includes within which RU (s) the actual ACK (s) are contained within the M-BA or are self-contained in the M-BA itself. A receiver WDEV receives and processes an earlier portion of the M-BA to determine where, with respect to the RU (s), the corresponding actual ACK (s) within the M-BA will BA are located.

In addition, in yet another example of operation and implementation, WDEV supports 310 the communication with the WDEVs 130 . 132 , The WDEV 310 is configured to generate a trigger frame (which may be, for example, an OFDMA frame) that specifies certain information. In some examples, the trigger frame indicates a first plurality of Resource Units (RUs) to be retrieved from the WDEVs 390 to 391 are to be used when transmitting a second OFDMA frame to the wireless communication device.

Then the WDEV 310 then configured to send the trigger frame to the WDEVs 390 to 391 transfers. The WDEV 310 is then configured to derive from the WDEVs based on the first plurality of RUs specified within the trigger frame 390 to 391 receives a UL-MU-PPDU (which, for example, may also be an OFDMA frame). It should be noted that the second OFDMA frame according to the OFDMA signaling first information from the WDEV 390 and second information from the WDEV 391 may include.

The WDEV 310 is then configured to generate an M-BA (which may also be an OFDMA frame, for example) based on the receipt of the second UL-MU-PPDU, indicating the actual (n) respective (n ) ACK (s) within the M-BA within one or more RU (s) extending over the respective one or more RUs within which the information from the WDEVs 390 to 391 were received.

If, for example, the WDEV 390 first information within a first RU transmits and the WDEV 391 transmits second information within a second RU, then one by the WDEV 310 received ACK of the first information from the WDEV 390 be contained within an RU of the M-BA and / or extend over an RU of the M-BA, which includes the RU and / or extends over the RU, within which the first information from the WDEV 390 through the WDEV 310 were received, and another by the WDEV 310 received ACK of the second information from the WDEV 391 the M-BA will be contained within another RU and / or extend over another RU of the M-BA comprising another RU and / extending over another RU, within which the second information is from the WDEV 391 through the WDEV 310 were received. It should be noted that the ACK of the first information from the WDEV 390 and at the other ACK the second information from the WDEV 391 can act to one or more ACKs (for example, in some cases, a single ACK can be used to both those of the second information from the WDEV 391 to confirm.

For certain examples, the WDEV transmits 310 a first OFDMA frame containing a trigger frame for the WDEVs 390 to 391 includes. The WDEV 310 receives a second OFDMA frame from the WDEVs 390 to 391 who received the first information from the WDEV 390 which has been modulated within a first of the first plurality of RUs as indicated in the first OFDMA frame (eg trigger frame), and also second information from the WDEV 391 includes modulated within a second of the first plurality of RUs as indicated in the first OFDMA frame (eg trigger frame), and also third information from a third WDEV (eg, in addition to the WDEVs 390 to 391 another WDEV) modulated within a third of the first plurality of RUs as indicated in the first OFDMA frame (eg trigger frame). The WDEV 310 is then configured to generate a third OFDMA frame comprising a Multi-Block Acknowledgment (M-BA). The WDEV 310 is then configured to connect the third OFDMA frame comprising the M-BA to the WDEVs 390 to 391 and in addition to the WDEVs 390 to 391 to the other WDEV transmits. The M-BA includes a first acknowledgment (ACK), which is based on the receipt of the first information from the WDEV 390 within the first of the first plurality of RUs, wherein the first ACK is modulated within a first of the second plurality of RUs as indicated in the first OFDMA frame (eg trigger frame). The M-BA also includes a second ACK that is responsive to receiving both the second information from the WDEV 391 that were modulated within the second of the first plurality of RUs, as well as the third information from the additional WDEV in addition to the WDEVs 390 to 391 which were modulated within the third of the first plurality of RUs. It is noted that the second ACK is modulated within a second of the second plurality of RUs, as indicated in the first OFDMA frame, which extends over the second of the first plurality of RUs and the third of the first plurality of RUs.

In yet other examples where a first, a second, and a third OFDMA frame exist between the WDEV 310 and the WDEVs 390 to 391 (and / or another WDEV in addition to the WDEVs 390 to 391 ) is the WDEV 310 configured to receive a fourth OFDMA frame, the third information from the WDEV 390 which were modulated within a first of the first plurality of RUs as indicated in the first OFDMA frame, and fourth information from the WDEV 391 which has been modulated within a second of the first plurality of RUs as indicated in the first OFDMA frame. The WDEV 310 is configured to generate a fifth OFDMA frame based on the reception of the fourth OFDMA frame.

This fifth OFDMA frame comprises a multi-block acknowledgment (M-BA). This M-BA comprises a first signal field (SIG) for the WDEV 390 which has been modulated within a first at least one RU of at least one of the first plurality of RUs or of the second plurality of RUs indicating a first RU of at least one of the first plurality of RUs or of the second plurality of RUs, within those the WDEV 390 receive a first acknowledgment (acknowledgment, ACK) from the wireless communication device responsive to receiving the third information from the WDEV 390 which were modulated within the first of the first plurality of RUs. It should also be noted that the first ACK follows the first SIG within the fifth OFDMA frame. This M-BA includes a second SIG for the WDEV 391 within a second at least one RU of at least one of the first plurality of RUs or of the second plurality of RUs indicating a second RU of at least one of the first plurality of RUs or of the second plurality of RUs within those the WDEV 391 to receive a second ACK from the wireless communication device responsive to receiving the fourth information from the WDEV 391 which were modulated within the second of the first plurality of RUs.

In yet other examples where a first, a second, and a third OFDMA frame exist between the WDEV 310 and the WDEVs 390 to 391 (and / or another WDEV in addition to the WDEVs 390 to 391 ) is the WDEV 310 configured to receive a fourth OFDMA frame, the third information from the WDEV 390 which were modulated within a first of the first plurality of RUs as indicated in the first OFDMA frame, and fourth information from the WDEV 391 which has been modulated within a second of the first plurality of RUs as indicated in the first OFDMA frame. The WDEV 310 is then configured to generate a fifth OFDMA frame comprising a Multi-Block Acknowledgment (M-BA) based on the receipt of the fourth OFDMA frame. This M-BA includes a first acknowledgment (ACK) based on receipt of the third information from the WDEV 390 which are modulated within a first RU extending over the first of the first plurality of RUs as indicated in the first OFDMA frame and within which the third information is from the WDEV 390 be modulated within the fourth OFDMA frame.

3A is a diagram that is an example 301 for Orthogonal Frequency Division Multiplexing (OFDM) and / or Orthogonal Frequency Division Multiple Access (OFDMA) multiple access orthogonal frequency division multiplexing. The modulation of OFDM may be considered as splitting an available spectrum into a plurality of narrow band subcarriers (e.g., relatively low data rate carriers). The subcarriers are contained within a section or band of the available frequency spectrum. This available frequency spectrum is divided into the subcarriers or tones used for the OFDM or OFDMA symbols and packets / frames. It should be noted that the terms "subcarrier" and "clay" can be used interchangeably. Typically, the frequency responses of these subcarriers are not superimposed, and they are orthogonal. Each subcarrier may be modulated using any of a variety of coding techniques for modulation (for example as shown by the vertical axis of the modulated data).

A communication device may be configured to perform the coding of one or more bits to generate one or more coded bits used to generate the modulated data (or, more generally, the data). For example, a processing circuitry and communications interface of a communications device may be configured to provide FEC (Forward Error Correction) code and / or Error Checking and Correction (ECC) code for one or more execute several bits to generate one or more coded bits. Examples of FEC code and / or ECC code may include turbo code, convolutional code, turbo trellis coded modulation (TTCM), turbo trellis code modulation (LDC), low density parity check (LDPC) code, RS Code (Reed-Solomon), BCH Code (Bose and Ray-Chaudhuri and Hocquenghem), BCC (Binary Convolutional Code), CRC (Cyclic Redundancy Check), and / or any other type ECC and / or FEC code and / or a combination of these, etc. It should be appreciated that multiple types of ECC and / or FEC code may be used in any of various implementations, including concatenation (eg, first a first ECC and / or FEC code followed by a second ECC and or FEC code, etc., such as based on an inner code / outer code architecture, etc.), parallel architecture (such as that the first ECC and / or FEC code acts on first bits while the first second ECC and / or FEC code acts on second bits, etc.) and / or any combination thereof. The one or more coded bits may then be subjected to modulation or symbol mapping to generate modulation symbols. The modulation symbols may include data intended for one or more receiver devices. It should be noted that such modulation symbols are generated using any of various types of modulation modulation techniques can. Examples of such encoding techniques for modulation may include BPSK (Binary Phase-Shift Keying), QPSK (Quadrature Phase-Shift Keying), 8-PSK (Phase-Shift Keying), 16-QAM (Quadrature Amplitude Modulation, Quadrature amplitude modulation), 32-APSK (Amplitude and Phase-Shift Keying), etc., uncoded modulation, and / or any other desired types of modulation including higher-order modulations comprising even a larger number of constellation points (e.g. Example 1024-QAM, etc.).

3B is a diagram that is another example 302 illustrated for OFDM and / or OFDMA. A transmitting device transmits modulation symbols over the subcarriers. It should be noted that such modulation symbols include modulation symbols for data, symbols for pilot signals for modulation (for example, for use in channel estimation, characterization, etc.) and / or other types of modulation symbols (for example, with other types of information contained therein) can. The OFDM and / or OFDMA modulation can be performed by performing simultaneous transmission of a large number of narrow band carriers (or multiple tones). In some applications, a guard interval (GI) or guard time is sometimes used between the various OFDM symbols to try to minimize the effects of intersymbol interference (ISI) that causes the effects of using multiple paths within the communication system which can cause particular problems with wireless communication systems.

Additionally, in addition, within the guard interval, as on the right side of 3A shown, a cyclic prefix (CP) and / or a cyclic suffix (CS) (for example, on the right side of 3A shown, which may be a copy of the CP) may be used to allow a switching time (such as when jumping to a new communication channel or subchannel) and to maintain the orthogonality of the OFDM and / or OFDMA symbols. In some examples, at the end portion of the data portion, a certain amount of information (eg, data bits) is copied and placed at the beginning of the data to form the frame / symbol (s). In a specific example, it should be considered that the data comprises the data bits x ₀ , x ₁ ,... X _N-Ncp ,..., X _N-1 , where the x _N-Ncp -th bit is the first Is the bit of the end portion of the data portion to be copied, then the bits X _N-Ncp ,..., X _{N-1 are} copied and placed at the beginning of the frame / symbol (s). It should be noted that such an end portion of the data portion which is copied and placed at the beginning of the data to form the frame / symbol (s) may also be shifted, cycled and / or copied more than once, etc., if desired in certain embodiments. Generally speaking, an OFDM and / or OFDMA system design is based on the expected delay spread within the communication system (e.g., the expected delay spread of the communication channel).

In a single user system in which one or more OFDM symbols or OFDM packets / frames are transmitted between a transmitter device and a receiver device, all of the subcarriers or tones are specially adapted for use in transmitting modulated data between the transmitter and the receiver Receiver device provided. In a multiple user system in which one or more OFDM symbols or OFDM packets / frames are transmitted between a transmitter device and multiple receivers or receiver devices, the various subcarriers or tones may be mapped to different respective receiver devices as described below with reference to FIG 3C is described.

3C is a diagram that is another example 303 illustrated for OFDM and / or OFDMA. When comparing OFDMA with OFDM, OFDMA is a multi-user version of the popular digital Orthogonal Frequency Division Multiplexing (OFDM) modulation scheme. Multiple access is achieved in OFDMA by allocating subsets of subcarriers to individual receiver devices or users. For example, one or more first subcarriers / tones may be assigned to a user 1, one or more second subcarriers / tones may be assigned to a user 2, etc., up to any desired number of users. In addition, such assignment of subcarriers / tones may be dynamic between different respective transmissions (eg, a first assignment for a first packet / first frame, a second second packet / frame assignment, etc.). An OFDM packet / frame may include more than one OFDM symbol. Similarly, an OFDMA packet / frame may include more than one OFDMA symbol. In addition, such assignment of subcarriers / tones may be dynamic between different respective symbols within a particular packet / frame or parent frame (eg, a first assignment of a first OFDMA symbol within a packet / frame, a second assignment of a second OFDMA symbol within the packet / frame, etc.). Generally speaking, an OFDMA symbol is a particular type of OFDM symbol, and the general reference to the term "OFDM symbol" in the present document includes both OFDM and OFDMA symbols (and the general reference to FIGS The term "OFDM packet / frame" in the present document includes both OFDM and OFDMA packets / frames and vice versa). 3C shows the example 303 in which the allocations of subcarriers to different users are intermixed (eg, subcarriers assigned to a first user do not include subcarriers adjacent to each other, and at least one subcarrier assigned to a second user is located between two subcarriers assigned to the first user). The different sets of subcarriers associated with each user may be considered as respective channels of a plurality of channels, all of which form the available subcarriers for OFDM signaling.

3D is a diagram that is another example 304 illustrated for OFDM and / or OFDMA. In this example 304 For example, first subcarriers assigned to a first user include a first subcarrier group disposed adjacent thereto, second subcarriers assigned to a second user include a second subcarrier group disposed adjacent, and so on .). The different contiguous groups of subcarriers associated with each user may be considered as respective channels of a plurality of channels, all of which form the available subcarriers for OFDM signaling.

3E is a diagram that is an example 305 SC signaling (single carrier signaling, single carrier signaling) is illustrated. The SC signaling comprises a single, relatively wide channel over which signals are transmitted, as compared to OFDM signaling. In contrast, in OFDM, multiple narrowband subcarriers or narrowband subchannels extend over the available frequency range, bandwidth or spectrum over which signals are transmitted within the narrowband subcarriers or narrowband subchannels.

In general, a communication device may be configured to include circuitry for processing and the communication interface (or, alternatively, circuitry for processing, such as those described in U.S. Patent Nos. 5,666,988, 4,874,874, 4,829,866, and 4,829,866) 2 B shown circuitry for processing 330a and / or the circuit arrangement for processing 330b ) configured to process received OFDM and / or OFDMA symbols and / or frames (and / or SC symbols and / or frames) and such OFDM and / or OFDMA symbols and / or or frame (and / or SC symbols and / or frames).

4A is a diagram that is an example 401 for an OFDM / A packet. This packet comprises at least one preamble symbol followed by at least one data symbol. The at least one preamble symbol includes information for use in identifying, classifying and / or categorizing the packet for appropriate processing.

4B is a diagram that is another example 402 for an OFDM / A packet of a second type. This package also includes a preamble and dates. The preamble is composed of at least one short training field (STF), at least one long training field (LTF) and at least one signal field (SIG). The data consists of at least one data field. Both in this example 402 as in the previous example 401 For example, the at least one data symbol and / or the at least one data field may generally be referred to as the payload of the packet. Among other things, STFs and LTFs can be used to help a device find out that a frame is ready to start, to synchronize timers, to select an antenna configuration, to set the receiver gain, to set certain modulation parameters for the remainder of the packet, a channel estimate for Uses such as beamforming, etc. In some examples, one or more STFs are used for gain adjustment (such as automatic gain control (AGC) adaptation), and a particular STF may be repeated one or more times (eg, repeated 1 time) in an example). In some examples, one or more LTFs are used for channel estimation, channel characterization, etc. (such as for determining a channel response, a channel transfer function, etc.), and a particular LTF may be repeated one or more times (e.g., repeated up to 8 times) an example).

The SIGs may include, among other things, various information describing the OFDM packet, including certain attributes such as, among other possible information, such as the data transfer rate, the packet length, the number of symbols within the packet, the channel width, the coding for modulation, the modulation coding set (MCS, Modulation Coding Set), the modulation type, whether the packet is a single user or multiple user frame, Frame length, etc. This disclosure, inter alia, provides a means by which at least one second variable length SIG may be used to include any desired amount of information. Using at least one SIG having a variable length, different amounts of information may be given therein to suit them for any situation.

Below, various examples of possible forms of a preamble for use in wireless communication as described in the present document are described.

4C is a diagram that is another example 403 for at least a portion of an OFDM / A packet of another type. A field within the packet may be copied there one or more times (for example, where N is the number of times the field is copied, and where N is any positive integer greater than or equal to one).

It should be noted that the information contained in the various fields in the various examples provided in the present document may be encoded using different encoders. In some examples, two independent BCC (Binary Convolutional Code) encoders are implemented to encode information corresponding to different respective MCSs (Modulation Coding Sets) for, inter alia, the respective ones User data can be selected and / or optimized on the respective channel. Examples of different communication channels are below with reference to 6D described.

In addition, in some examples, a wireless communication device generates content contained in the various SIGs (eg, SIGA and / or SIGB) to signal one or more wireless communication devices MCS (s) to direct which MCS (s) for them one or more other wireless communication devices is to be used with respect to one or more communications. Additionally, in some examples, content contained in at least a first SIG (eg, SIGA) includes information to indicate at least one operating parameter for use in processing at least one second SIG (eg, SIGB) within the same OFDM / A packet.

In the present document, various OFDM / A frame structures for use in communication between wireless communication devices are presented, particularly showing OFDM / A frame structures corresponding to one or more resource units (RUs). Such OFDM / A frame structures may include one or more RUs. It should be noted that these various examples may include different total numbers of sub-carriers, different numbers of sub-carriers for data, different numbers of sub-carriers for pilot signals, and so on. Different RUs may also have different other features (for example, a different spacing between the subcarriers, different subcarrier densities, implementation within different frequency bands, etc.).

5F is a diagram that is an example 506 for selecting among different OFDM / A frame structures for use in the communication between wireless communication devices, wherein in particular one or more resource units (RUs) have corresponding OFDM / A frame structures 350 are shown. This diagram can be considered to have some similarities with the allocation of subcarriers to different users, as in 4D and also shows how each OFDM / A frame structure is connected to one or more RUs. It should be noted that these various examples may include different total numbers of sub-carriers, different numbers of sub-carriers for data, different numbers of sub-carriers for pilot signals, and so on. Different RUs may also have different other features (for example, a different spacing between the subcarriers, different subcarrier densities, implementation within different frequency bands, etc.).

In one example, the OFDM / A frame structure is 1 351 from at least one RU 1 551 , In another example, the OFDM / A frame structure 1 351 from at least one RU 1 551 and at least one RU 2 552 , In another example, the OFDM / A frame structure 1 351 from at least one RU 1 551 , at least one RU 2 552 and at least one RU m 553 , Analogously, the OFDM / A frame structure 2 352 up to the OFDM / A frame structure n 353 from any combination of different RUs (for example, including one or more any of the RU 1 551 up to the RU m 553 selected RU (s)).

5G is a diagram that is an example 507 for different types of different Resource Units (RUs). In this example 502 includes the RU 1 551 total A1 subcarrier, A2 subcarrier for data (D), A3 subcarrier for pilot signals (P) and A4 unused subcarrier. The RU 2 552 comprises a total of B 1 subcarriers, B2 D subcarriers, B3 P subcarriers and B4 unused subcarriers. The RU N 553 comprises a total of C1 subcarriers, C2 D subcarriers, C3 P subcarriers, and C4 unused subcarriers.

Taking into account the different RUs (for example from the RU 1 551 up to the RU N 553 ) increases the total number of subcarriers over the RUs of the RU 1 551 up to the RU N 553 (for example A1 <B1 <C1). Moreover, when looking at the different RUs (for example from the RU 1 551 up to the RU N 553 ) the ratio of the subcarriers for pilot signals to the subcarriers for data on the RUs of the RU 1 551 up to the RU N 553 (for example A3 / A2> B3 / B2> C3 / C2).

It should be noted that in some examples, different RUs may include a different number of total subcarriers and a different number of subcarriers for data, and yet the same number of subcarriers for pilot signals.

As can be seen, this disclosure provides various options for mapping subcarriers for data and for pilot signals (and sometimes unused subcarriers that do not include modulation data or are free of modulation data) in OFDMA frames or packets (note that FIG Terms "frame" and "packet" may be used interchangeably herein) in various communications between communication devices including both uplink (UL) and downlink (DL), such as with respect to an access point (AP) , It should be noted that the term "user" generally means a wireless communication device implemented in a wireless communication system (for example, a wireless station (STA) or an access point (AP) within a wireless local area network (WLAN / WiFi)). can be understood. For example, a user may be considered as a particular wireless communication device (eg, a wireless station (STA) or access point (AP) or AP operated STA within a wireless communication system). In this disclosure, the localized and distributed mapping of such subcarriers or sounds to different users in an OFDMA context (such as with reference to FIGS 4C and 4D including the allocation of subcarriers for one or more users).

Some versions of the standard IEEE 802.11 have the following Fast Fourier Transform (FFT) sizes on the physical layer (PHY): 32, 64, 128, 256, 512.

These PHY-FFT magnitudes are mapped to different bandwidths (BWs) (which, for example, can be achieved using different sub-clocking ratios or factors applied to a first clock signal, to different other clock signals, such as a second clock signal, a third Clock signal, etc.). In many instances, this disclosure refers to FFT sizes rather than bandwidth, since an FFT size is the specific allocation of subcarriers, RUs, etc. for a user and the total system bandwidth using one or more mappings of subcarriers, RUs, etc . certainly.

This disclosure presents various ways in which the mapping of data from N users to the system bandwidth tones (localized or distributed). For example, if the system bandwidth uses a 256 FFT, the individual modulation data for 8 different users may each use a 32 FFT. Alternatively, if the system bandwidth uses a 256 FFT, the individual modulation data may each use a 64 FFT for 4 different users. In another alternative, if the system bandwidth uses a 256-FFT, the individual modulation data may each use a 128-FFT for 2 different users. In addition, any number of other combinations are possible where unequal bandwidth is allocated for different users, such as a 32-FFT for 2 users, a 64-FFT for one user, and a 128-FFT for the last user.

A localized mapping (e.g., contiguous subcarrier allocations for different users, such as with reference to FIG 3D ) is preferable for certain applications, such as low mobility users (for example, who remain stationary or substantially stationary and whose location does not change often), since a subband may be allocated for each user based on at least one feature. An example of such a feature includes the allocation to a subband that maximizes its performance (for example, highest signal-to-noise ratio or highest capacity in a multi-antenna system). The respective wireless communication devices (users) receive frames or packets (eg, beacons, null data packets, data packets, etc.) and / or other frame or packet types over the entire band and report their preferred subband or list preferred subbands back. Alternatively, a first device (eg, a transmitter, an AP, or an STA) transmits at least one OFDMA packet to a second communication device, and the second device (eg, a receiver, an STA, or another STA) may be configured such that It measures the initial transmission of the first device occupying the entire band and chooses a best / good or preferred subband. The second device may be configured to transmit the selection of information about a feedback, etc. to the first device.

In some examples, a device is configured to utilize PHY implementations for 32-FFT, 64-FFT, and 128-FFT as OFDMA blocks within a 256-FFT system bandwidth. When this occurs, there may be some unused subcarriers (for example, gaps in unused subcarriers within the system bandwidth used). This can also be the case with the lower FFT sizes. In some examples, if the FFT is an integer multiple of another integer, the larger FFT may be a multiple of the lower FFT (for example, a 512 FFT may be an exact double of two implementations with a 256 FFT). When a 256 FFT is used for the system bandwidth, in some examples, the available number of tones that can be divided among the various users that belong to the OFDMA frame or packet (DL or UL) is 242.

In some examples, a PHY implementation may leave sub-carrier gaps between the respective wireless communication devices (users) (for example, unused sub-carriers). For example, users 1 and 4 may each use a 32 FFT structure occupying a total of 26 × 2 = 52 subcarriers, user 2 may use a 64 FFT occupying 56 subcarriers, and user 3 may have a 128 FFT structure. Use FFT occupying 106 subcarriers, giving a total of 214 subcarriers, with 28 subcarriers not being used.

In another example, multiplexing occurs only for 32 FFT users, allowing up to 9 users with 242 subcarriers - (9 users × 26 RUs) = 8 unused subcarriers between the users. In yet another example, multiplexing is done for 64 FFT users with 242 subcarriers - (4 users × 56 RUs) = 18 unused subcarriers.

The unused subcarriers may be used to provide better separation between the sub-carriers, especially in uplinks where the user energy travels due to imperfect synchronization of time / frequency / power, resulting in inter-carrier interference (ICI) Provide users.

6A is a diagram that is another example 601 illustrated for different types of different RUs. In this example 601 For example, the RU 1 comprises X1 subcarriers, X2 subcarriers for data (D), X3 subcarriers for pilot signals (P), and X4 unused subcarriers. The RU 2 comprises a total of Y1 subcarriers, Y2 D subcarriers, Y3 P subcarriers and Y4 unused subcarriers. The RU q comprises a total of Z1 subcarriers, Z2 D subcarriers, Z3 P subcarriers and Z4 unused subcarriers. It should be noted that in this example 601 different RUs may have a different spacing between the subcarriers, different densities of subcarriers, which may be implemented within different frequency bands, may extend to different areas within at least one frequency band, etc.

6B is a diagram that is another example 602 illustrated for different types of different RUs. This diagram shows an RU 1 comprising 26 contiguous subcarriers with 24 subcarriers for data and 2 subcarriers for pilot signals; an RU 2 comprising 52 contiguous subcarriers with 48 subcarriers for data and 4 subcarriers for pilot signals; an RU 3 comprising 106 contiguous subcarriers with 102 subcarriers for data and 4 subcarriers for pilot signals; an RU 4 comprising 242 contiguous subcarriers with 234 subcarriers for data and 8 subcarriers for pilot signals; an RU 5 comprising 484 contiguous subcarriers with 468 subcarriers for data and 16 subcarriers for pilot signals; and an RU 6 comprising 996 contiguous subcarriers with 980 subcarriers for data and 16 subcarriers for pilot signals.

It is noted that the RU 2 and the RU 3 each comprise a first / same number of sub-carriers for pilot signals (for example, 4 sub-carriers for pilot signals respectively), and the RU 5 and the RU 6 each comprise a second / equal number of sub-carriers for pilot signals (for example, 16 subcarriers each for pilot signals). The number of sub-carriers for pilot signals remains the same or increases across the RUs. It should be noted that some of the RUs comprise an integer multiple of subcarriers of other RUs (for example, the RU comprises 2 a total of 52 subcarriers, which is 2x the total number of 26 subcarriers of RU 1, and the RU 5 comprises 242 subcarriers, which is 2x the total number of 242 subcarriers of RU 4).

6C is a diagram that is an example 603 for various types of FFT (Fast Fourier Transform) quantities indicated on a communication protocol at the Physical Layer (PHY). The device 310 is configured to generate and transmit OFDMA packets based on various PHY-FFT sizes as specified within at least one communication protocol. Some examples of PHY-FFT sizes, such as based on IEEE 802.11 include PHY FFT sizes, such as 32, 64, 128, 256, 512, 1024, and / or other sizes.

In one example, the device is 310 is configured to generate and transmit an OFDMA packet based on the RU 1 comprising 26 contiguous subcarriers with 24 subcarriers for data and 2 subcarriers for pilot signals, and that this OFDMA packet based on a PHY FFT 32 (For example, the RU 1 fits into the PHY-FFT 32). In one example, the device is 310 is configured to generate and transmit an OFDMA packet based on the RU 2 comprising 52 contiguous subcarriers with 48 subcarriers for data and 4 subcarriers for pilot signals, and that this OFD MA packet is based on a PHY protocol. FFT 56 (for example, the RU 2 fits into the PHY-FFT 56) transmits. The device 310 uses, on the basis of at least one communication protocol, different size PHY FFTs of different size RUs.

It should be noted that any combination of RUs may be used. In another example, the device is 310 is configured to generate and transmit an OFDMA packet based on two RU 1 based RUs and one RU 2 based RU based on a PH FFT 128 (for example, two RUs based on the RU 1 and one RU based on the RU 2 total of 104 subcarriers). The device 310 is configured to generate and transmit arbitrary OFDMA packets based on any combination of RUs that fit into a suitably selected PHY FFT size of at least one communication protocol.

It should also be noted that any particular RU may be subdivided or partitioned into subsets of subcarriers to provide modulation data for one or more users (for example as described with reference to FIG 3C or 3D ) respectively.

6D is a diagram that is an example 604 for different channel bandwidths and the relationship between them. In one example, a device (for example, the device 310 ) is configured to generate and transmit any OFDMA packet based on any number of OFDMA frame structures within different communication channels having different channel bandwidths. For example, a 160 MHz channel may be divided into two 80 MHz channels. An 80 MHz channel may be divided into two 40 MHz channels. A 40 MHz channel may be divided into two 20 MHz channels. It should also be noted that such channels may be located within the same frequency band, same frequency subband, or alternatively different frequency bands, in different frequency subbands, etc.

In a wireless communication system (for example, a wireless local area network system (WLAN / WiFi), etc.) in which a wireless communication device acting as a central control unit (for example, an access point (AP), an access point operated wireless station (STA) , etc.) make decisions about which device (s) (eg, other wireless devices (WDEVs), other wireless stations (STAs), etc.) are allowed access to the medium, resources (e.g. resource units (Resource Units, RUs) after having considered competing resource requests from one or more participating devices (s) (eg, other WDEVs, other STABs, etc.).

The wireless communication device (for example, an access point (AP)) acting as a central control unit provides resource allocations for each given data exchange phase, wherein each data exchange phase could provide resource allocations to more than one participating STAs corresponding to a single time slot.

The resource allocations to different devices (eg, other WDEVs, other STAs, etc.) are orthogonal in various ways (eg, frequency orthogonal, spatially orthogonal, etc.).

The WDEV (for example, an AP) acting as a central control unit gives the resource allocation for each of the devices (eg, further WDEVs, other STAs, etc.) in one Broadcast frames (for example, a trigger frame or other signal).

One device (eg, another WDEV, another STA, etc.) prepares data for transmission to the central control unit WDEV (eg, an AP) after analytically decomposing the resource allocation information provided in the trigger frame has recognized a self allocated resource allocation. Several devices coordinated by means of the WDEV (for example an AP) acting as the central control unit (for example further WDEVs, further STAs, etc.) then transmit uplink multi-user data frames (UL-MU data frames) to the WDEV (FIG. for example the AP).

It should be appreciated that reference to an STA and / or an AP in various operational examples in the present document may generally be any type of wireless communication device (eg, AP, STA, etc.). Such references to AP, STA, and / or users, etc. are used in illustrative examples in various examples, but they may be broadly understood to be any type of wireless communication devices.

7A is a diagram that is an example 701 for signal exchange between wireless communication devices.

In an example of operation, a WDEV (eg, an AP) acting as a central control unit, upon receipt of the UL MU data, acknowledges receipt of data by issuing a MU OFDMA block acknowledgment (BA), a single user multiple block acknowledgment (SU-M -BA) or a multiple user multiple block acknowledgment (MU-M-BA).

This disclosure proposes several methods for allocating and indicating resource units (RUs) for a central control unit WDEV (eg, an AP) for transmitting acknowledgment information to multiple receivers (eg, M-BA).

One approach works by carrying the DL-M-BA RU allocation in a DL frame. For example, the signaling method may be performed within a Trigger PPDU (Trigger PLCP Protocol Data Unit) (where PLCP corresponds to the Physical Layer Convergence Procedure). The signaling method may be performed using a special identifier (ID) of a wireless station (STA) (STA-ID) in the SIG-B of the physical layer header (PHY) of the DL-PPDU.

One approach works by using a semi-implicit RU for the DL-M-BA based on a UL RU of the previous PPDU. For example, the RU for the M-BA is based on the RU used by an STA for the previous UL MU PPDU. Such a signaling method may be performed using a special STA ID in the SIG-B of the PHY header of the DL-PPDU containing the acknowledgment information.

Design Option 1:

7B is a diagram that is an example 702 of a trigger frame for use in the signal exchanges between wireless communication devices.

Possibility Number 1:

Allocation information in a type-specific field of the trigger frame.

In the common information field of the trigger frame, set the trigger type to zero (which, for example, indicates a normal trigger for a UL data transfer). In the field "Trigger-dependent common info." Set the bit "M-BA-RU available" to one.

If the bit "M-BA-RU present" has the value 1 within the field for user-specific information ("User-specific info."), Then the field for the M-BA RU allocation in each field is "Trigger-dependent user-specific info ." available. In addition, within the field "User-specific info." In the field "Trigger-dependent user-specific info.", Set the field for the M-BA-RU allocation to the value that the RU allocation of the DL-M-BA for the corresponding STA indicates. In addition, within the User Info field, the M-BA RU allocation field may have a different length according to the pattern and size of the RU.

Design Option 1A:

8B is a diagram that is an example 802 for a table that illustrates bit indexes for the M-BA allocation field of 8A shows. Around specify the RU used to receive the DL-M-BA, the following 7-bit table 1 ( 10 ) can be used to specify an RU in the range between 26 and 996 tones and within the bandwidth of 20 to 160 MHz. Each user requires 8 bits to specify the M-BA RU allocation. One of the 8 bits indicates a portion of the bandwidth (eg upper 80 MHz, lower 80 MHz). The remaining 7 bits give a further detail of the allocation according to the table of 8A at.

Design Option 1B:

Optional coding of the M-BA RU allocation field:

To specify the RU used to receive the DL-M-BA, the following 4-bit table 2 may be used to specify an RU in the range between 106 and 996 tones and within the bandwidth of 20 to 160 MHz , Each user requires 5 bits to specify the M-BA RU allocation. One of the 4 bits indicates a portion of the bandwidth (for example upper 80 MHz, lower 80 MHz). The remaining 4 bits indicate a further detail of the allocation according to Table 2.

Design Option 1C:

Coding of the M-BA-RU allocation field:

To indicate the RU used to receive the DL-M-BA, the following 4-bit table 3 may be used to specify an RU in the range between 242 and 996 tones and within the bandwidth of 20 to 160 MHz , Each user requires 4 bits to specify the M-BA RU allocation. One of the 4 bits indicates a portion of the bandwidth (for example upper 80 MHz, lower 80 MHz). The remaining 3 bits indicate a further detail of the allocation according to Table 2.

Comparison of the design options 1A, 1B, 1C:

As can be seen, the design option 1A allows a larger allocation choice for the DL-M-BA. This option uses the relatively largest number of bits (for example, 8 bits per user in the trigger PPDU).

As can be seen, the design option 1C allows the lowest possible allocation choice for the DL-M-BA. This option uses the relatively fewest number of bits to signal DL-M-BA allocations (for example, 4 bits per user in the trigger PPDU).

User-specific SIG-B content within the DL-PPDU containing M-BA frames:

An STA that finds its STA ID in any user-specified STA ID field uses the relative position of this field for user-specific information within the list of user-specific fields to find its audio allocation (for example, the STA used with the matches the STA ID found in the first user-specific information field in the # 1-column column in the HE-SIG-B shared content table in FIG 13 , In addition, in some examples, the STA used matches the STA ID found in the second custom information field, the audio allocation in the # 2 column in the common information table for HE-SIG-B in FIG 13 ,

Each user determines from the values in the common information table whether there is a user-specific spatial allocation table. A spatial allocation table is present in the user-specific subfield when more than one receiver is directed to a specific audio allocation in the common information table. This can also happen if only one recipient is identified by means of the STA-ID.

The presence of a special STA ID value in a user-specific field indicates that the associated RU is for multiple receiving STAs. The corresponding audio allocation column in the common HE-SIG-B content table for the user-specific field still matches the position of the user-specific field within the list of user-specific fields. Within a PPDU, the particular STA ID value corresponding to the generic broadcast ID indicates an RU for any STA for which no RU is specified by a single STA ID value in any user-specific field within the same PPDU ,

The particular STA ID value corresponding to the broadcast ID may be defined to mean a subset of all STABs, for example, only STAs that are expecting to receive an acknowledgment and not otherwise using a STA ID Values in other fields are identified for STA-specific information of the same PPDU. For example, an M-BA Broadcast ID indicates any STA that is expecting to receive an M-BA and its STA-ID is not listed in any other RU allocation within the same DL-PPDU. The value of the special STA ID may be any reserved value of the STA ID. For example, an additional STA ID value indicates any STA that is not individually listed in a STA ID of the STA-specific information and is not expected to receive any FET information, and therefore not with the M-BA broadcast ID matches. It should be noted that this STA could find another MAC broadcast PPDU, such as a trigger PPDU for a subsequent phase of the UL OFDMA.

The user-specific SIG-B information and payload information is passed to the next layer (for example, the Media Access Control (MAC) layer) which determines the frame type and determines whether any acknowledgment information is addressed to that STA by: examines the MAC addressing fields (for example, as in 11A shown).

11A is a diagram that is an example 1101 for user-specific information of a DL-M-BA-HE-SIG-B.

Semi-implicit RU signaling in design option 2:

11B is a diagram that is an example 1102 for semi-implicit RU signaling.

An M-BA comprising the user N is transmitted on the 52/106/242/484/996 RU, which comprises the RU used by the user N for the immediately preceding UL transmission.

According to the sound models of certain wireless communication standards, protocols and / or best practices (such as the sound model of the interim design of the under development) Standards IEEE 802.11ax of the IEEE 802.11 draft P802.11ax_D0.1.pdf), there can be only one arbitrary arbitrary size allocation greater than 26 tones, which includes any given 26-note allocation. For example, mapping a UL-OFDMA allocation to a DL-M-BA arbitration of arbitrary size is one-to-one if the rule of the first subitem above is followed (for example, the mapping is unique).

DL-M-BA PPDU allocations are based on UL PPDU allocations, and therefore there is no need to specify a DL-M-BA PPDU RU within the trigger frame preceding the UL transmission. This is costly for SIG-B (for example, it reduces the effort). In some examples, there may not be a need for a user-specific DL-M-BA RU within the trigger PPDU.

Generalized semi-implicit M-BA RU signaling:

Generally speaking, in accordance with the sound models of particular wireless communication standards, protocols and / or best practices (such as with reference to the sound model of the interim draft of the developing standard IEEE 802.11ax of the IEEE 802.11 draft P802.11ax_D0.1.pdf) only give an arbitrary allowance of arbitrary size greater than X tones, which includes any given tone allocation greater than X. Sounds is. In some examples, mapping a UL OFDMA allocation of any size to an equal or larger DL-M-BA allocation is unique. This allows the use of several possible DL-M-BA allocations.

User-specific HE-SIG-B information in design option 2:

It should also be noted that in some examples, with regard to the user-specific SIG-B content within the DL-PPDU containing M-BA frames, the configuration of the user-specific SIG-B content of option 2 is identical to that of option 1 (for example, many of the details described above).

Example (1) for Design Option 2 plus Wireless Broadcast Station Identifier (ID) (STA ID):

12A is a diagram that is an example 1201 for user-specific information of a wireless broadcast station (STA) identifier HE-SIG-B.

Case with only one RU for the M-BA:

An STA checks whether its STA ID is listed in the SIG-B field "User-specific Info." Of the OFDMA PPDU of the M-BA. Each STA uses the RUs corresponding to its STA-ID to determine which allocation to decode in a currently received PPDU (for example, the OFDMA PPDU of the M-BA).

If an STA does not find its STA ID, the STA checks whether an RU is specified using the M-BA broadcast ID (in this case, only one RU is specified using the M-BA Broadcast ID). The STAs use this RU to decode the M-BA if it expects an M-BA (if there is only one M-BA Broadcast ID). Please refer 16B for the case in which several M-BA broadcast IDs exist.

Otherwise, the STA checks whether an RU is specified by means of a general broadcast ID (for example, only one RU can be specified using the general broadcast ID). The STA uses this RU to decode broadcast data, such as a trigger frame.

Example (2) for design option 2 plus STA-ID for broadcast STAs:

12B is a diagram that is another example 1202 for user-specific information of a HE-SIG-B comprising a broadcast STA-ID.

Case with more than one RU for the M-BA using the Broadcast M-BA ID:

An STA checks whether its STA ID is listed in the SIG-B field "User-specific Info." Of the OFDMA PPDU of the M-BA. Each STA uses the RUs corresponding to its STA ID to determine which allocation to decode in a currently received PPDU.

If a STA does not find its STA ID, then the STA checks to see if an RU is specified using the M-BA Broadcast ID. If there is more than one M-BA broadcast ID, then:
The STA selects the user-specific field that includes an RU that includes the RU that was used by the STA for the previous UL MU transmission.

As an example, in a specific implementation, due to the definition of the sound model in FIG IEEE 802.11 , P802.11ax_D0.1, the RU of any particular size encompassing any given 26-Tone RU is unique, there is no ambiguity in the allocation used for the M-BA. In some examples, the generalized form of this rule set forth above still applies in this case.

The STAs use this RU to decode the M-BA when it is awaiting an M-BA.

Otherwise, the STA checks whether an RU is specified by means of a general broadcast ID (only one RU can be specified using the general broadcast ID). In some examples, the STA uses this RU to decode broadcast data, such as a trigger frame.

Example (3) for design option 2 plus STA-ID for broadcast STAs:

13 is a diagram that is another example 1300 for user-specific information of a HE-SIG-B comprising a broadcast STA-ID. In some implementations, the broadcast ID may be placed in the user specific info field of the trigger frame for the same purpose. An STA checks to see if its STA ID is listed in the User Info box of a trigger frame. Each STA uses the RUs corresponding to its STA ID to determine which allocation to decode in a currently received PPDU.

If a STA does not find its STA ID, then the STA checks to see if an RU is specified using the M-BA Broadcast ID. If there is more than one M-BA broadcast ID, then the STA selects the user-specific information field, the one RU comprising the RU used by the STA for the previous UL MU transmission.

As an example, in a specific implementation, due to the definition of the sound model in FIG IEEE 802.11 , P802.11ax_D0.1, the RU of any particular size encompassing any given 26-Tone RU is unique, there is no ambiguity in the allocation used for the M-BA. The previously generalized form of this rule still applies in this case. The STAs use this RU to decode the M-BA when it is awaiting an M-BA.

Otherwise, the STA checks whether an RU is specified by means of a general broadcast ID (only one RU can be specified using the general broadcast ID). In some examples, the STA uses this RU to decode broadcast data, such as a trigger frame.

The procedure 1401 is then operated by receiving the second OFDMA frame (eg, via the communication interface of the wireless communication device) from the plurality of other wireless communication devices based on the first plurality of RUs specified within the first OFDMA frame. It should be noted that the second OFDMA frame comprises first information from a first of the plurality of further wireless communication devices and second information from a second of the plurality of further wireless communication devices (block 1430 ).

The procedure 1401 is continued by generating the third OFDMA frame based on the reception of the second OFDMA frame (block 1440 ). The procedure 1401 is continued by transmitting the third OFDMA frame (eg, via the communication interface of the wireless communication device) to the plurality of other wireless communication devices based on the second plurality of RUs specified within the first OFD-MA frame (block 1450 ).

14B is a diagram showing another embodiment of a method 1402 illustrated for execution by means of one or more wireless communication devices. The procedure 1402 starts at step 1411 by generating a first OFDMA frame (block 1411 ). In some examples, the first OFDMA frame includes information indicating a first plurality of resource units (RUs) to be used by a plurality of other wireless communication devices when transmitting a second OFDMA frame to the wireless communication device ( block 1413 ).

The procedure 1402 is continued by transmitting the first OFDMA frame (for example via a communication interface of the wireless communication device) to the plurality of further wireless communication devices (block 1421 ).

The procedure 1402 is then operated by receiving the second OFDMA frame (eg, via the communication interface of the wireless communication device) from the plurality of other wireless communication devices based on the first plurality of RUs specified within the first OFDMA frame (block 1431 ).

The procedure 1401 is continued by generating the third OFDMA frame based on the reception of the second OFDMA frame (block 1441 ). In some examples, the third OFDMA frame includes information indicating second RUs. For example, an initial portion of the third OFDMA frame indicates second RUs within which ACKs of an M-BA are later included in the third OFDMA frame (Block 1443 ).

The procedure 1402 is continued by transmitting the third OFDMA frame (for example, via the communication interface) to the further wireless communication devices (for example, based on second RUs included in an initial portion of the third OFDMA frame, such as within one or more signal fields (SIG (s)) within the third OFDMA frame) (Block 1451 ).

15 is a diagram illustrating another embodiment of a method 1500 illustrated for execution by means of one or more wireless communication devices. The procedure 1500 becomes at step 1510 by generating a first Orthogonal Frequency Division Multiple Access (OFDMA) frame indicating a plurality of resource units (RUs) to be used by a plurality of other wireless communication devices as they are transmit a second OFDMA frame to the wireless communication device. The procedure 1500 becomes at step 1520 by transmitting the first OFDMA frame (for example, via a communication interface of the wireless communication device) to the plurality of further wireless communication devices;
The procedure 1500 becomes at step 1530 continuing by receiving, based on the plurality of RUs specified within the first OFDMA frame, the second OFDMA frame (eg, via the communication interface of the wireless communication device) of the plurality of other wireless communication devices. In some examples, the second OFDMA frame comprises, as in step 1532 shown first information modulated within a first of the plurality of RUs as indicated in the first OFDMA frame from a first of the plurality of further wireless communication devices and second within a second of the plurality of RUs as in the first one OFDMA frame, modulated information from a second one of the plurality of other wireless communication devices. In addition, the second OFDMA frame includes in further examples, as in step 1534 and third information modulated within a third of the plurality of RUs, as indicated in the first OFDMA frame, from a third of the plurality of other wireless communication devices.

The procedure 1500 becomes at step 1540 by generating a third OFDMA frame based on the receipt of the second OFDMA frame. In some examples, the third OFDMA frame comprises, as in step 1542 a first response to the first information modulated within a first RU extending over the first of the plurality of RUs, modulated information from the first one of the plurality of further wireless communication devices, and also comprising a second response to the second, within a second RU extending over the second of the plurality of RUs, modulated information from the second of the plurality of other wireless communication devices. In addition, in other examples, as in step 1544 The second answer also shows the third information from the third of the plurality of other wireless communication devices, and the second RU extends over both the second of the plurality of RUs and the third of the plurality of RUs.
