Abstract

Methods and apparatus related to determining, communicating, and/or using delay information and described. A wireless terminal determines delay information corresponding to queued information that it intends to transmits. The delay information includes a minimum time to a transmission deadline indicating a minimum amount of time remaining before information will be discarded if not transmitted. The determined delay information is communicated to a base station in a control information report. Alternatives formats for the control information report are possible including a report type conveying only delay information and a report type conveying delay information and queue backlog count information jointly coded. A base station uses received delay information received from one or more wireless terminals to efficiently schedule uplink traffic channel segments.

    RELATED APPLICATIONS
  • [0001]
    The present application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/752,973, filed on Dec. 22, 2005, titled “COMMUNICATIONS METHODS AND APPARATUS”, and U.S. patent applications Ser. No. 11/333,792, filed on Jan. 17, 2006, titled “METHODS AND APPARATUS OF IMPLEMENTING AND/OR USING A DEDICATED CONTROL CHANNEL”, each of which is hereby expressly incorporated by reference.
  • FIELD OF THE INVENTION
  • [0002]
    The present invention relates to wireless communications methods and apparatus and, more particularly, to methods and apparatus related to determining, communicating, and/or using delay information.
  • BACKGROUND
  • [0003]
    In a multiple access wireless communications system in which a base station schedules air link resources to wireless terminals competing for those resources, different wireless terminals, at different times may have different needs. A wireless terminal's resource needs may vary as a function of: types of applications, quality of service requirements, queued backlog, time data/information to be transmitted by the wireless terminal has been waiting in a queue, and/or data/information latency requirements. Control information about a wireless terminal reported to a base station by the wireless allows a base station's scheduler to characterize the wireless terminal's needs and weight the wireless terminal's needs against those of other wireless terminal's competing for the air link resources, e.g., competing for uplink traffic channel segments. Typically, some data/information waiting to be transmitted by a wireless terminal is delay-sensitive data/information, e.g., voice traffic, gaming traffic, etc. It would be beneficial if methods and apparatus provided for determining, reporting, communicating, and/or using delay information. A base station receiving delay sensitive information, e.g., delay sensitive information associated with uplink transmission backlog, could benefit from such knowledge in performing scheduling. More efficient scheduling methods and apparatus can lead to better a quality of service for users, higher user satisfaction and/or higher overall throughput.

  • DETAILED DESCRIPTION
  • [0040]
    FIG. 1 is drawing of an exemplary wireless communications system 100 implemented in accordance with various embodiments. Exemplary wireless communications system 100 is, e.g., an orthogonal frequency division multiple (OFDM) multiple access wireless communications system.
  • [0041]
    Exemplary wireless communications system 100 includes a plurality of base stations (base station 1 102, . . . , base station M 104). Each base station (102, 104) has a corresponding wireless coverage area (cell 1 106, cell M 108), respectively. System 100 also includes network node 118 which is coupled to base stations (102, 104) via network links (120, 122), respectively. Network node 118 is also coupled to other network nodes and/or the Internet via link 124. Network links (120, 122, 124) are, e.g., fiber optic links. System 100 may also include cells with multiple sectors and/or cells using multiple carriers.
  • [0042]
    System 100 also includes a plurality of wireless terminals. At least some of the wireless terminals are mobile nodes which may move throughout the communication system. In FIG. 1, wireless terminals (WT 1 110, WT N 112) are located in cell 1 106 and coupled to base station 1 102 via wireless links (126, 128), respectively. In FIG. 1, wireless terminals (WT 1114, WT N′ 116) are located in cell M 108 and coupled to base station M 104 via wireless links (130, 132), respectively. In accordance with various embodiments, at least some of the wireless terminals communicate delay information corresponding to data to be transmitted to a base station. In accordance with various embodiments, a base station performs scheduling of uplink air ink resources, e.g., uplink traffic channel segments, as a function of received delay information from wireless terminals.
  • [0043]
    FIG. 2 is a drawing of an exemplary wireless terminal 200 e.g., mobile node, in accordance with various embodiments. Exemplary wireless terminal 200 may be any of the exemplary wireless terminals (110, 112, 114, 116) of system 100 of FIG. 1.
  • [0044]
    Wireless terminal 200 includes a receiver module 202, a transmitter module 204, a processor 206, user I/O devices 208, and a memory 210 coupled together via a bus 212 over which the various elements interchange data and information. Memory 210 includes routines 214 and data/information 216. The processor 206, e.g., a CPU, executes the routines 214 and uses the data/information 216 in memory 210 to control the operation of the wireless terminal 200 and implement methods.
  • [0045]
    Receiver module 202, e.g., an OFDM receiver, is coupled to receive antenna 203 via which the wireless terminal 200 receives downlink signals. Downlink signals include assignment signals including assignments of uplink communications resources e.g., assignments of uplink traffic channel segments. Transmitter module 204, e.g., an OFDM transmitter, is coupled to transmit antenna 205, via which the wireless terminal 200 transmits uplink signals to a base station. Uplink signals include e.g., control information reports including delay information reports, backlog information reports, and/or joint delay/backlog information reports. Uplink signals also include uplink traffic channel segment signals conveying packets of information from transmission queues. Transmitter module 204 transmits at least some delay information determined by transmission delay determination module 218. In some embodiments, transmitter module 204 transmits first and second maximum queuing delays corresponding to first and second transmission queues to a base station. In some embodiments, the same antenna is used for receiver and transmitter.
  • [0046]
    User I/O devices 208, e.g., microphone, keypad, keyboard, mouse, switches, camera, speaker, display, etc., allow a user of wireless terminal 200 to input data/information and to access output data/information. User I/O devices 208 also allow a user of wireless terminal 200 to control at least some functions of the wireless terminal.
  • [0047]
    Routines 214 include a transmission delay determination module 218, a queue management module 220, a transmission control module 222, a backlog information generation module 224, and a coding module 226. Transmission delay determination module 218 determines delay information corresponding to data to be transmitted. Queue management module 220 manages one or more transmission queues. Operations of queue management module 220 include dropping data, e.g., a packet, from a transmission queue if a queuing delay associated with the data, e.g., the packet, exceeds maximum threshold associated with the data, e.g., a staleness threshold. Transmission control module 222 controls the transmitter module 204 to transmit maximum queuing delay information. In some embodiments, the transmission control module 222 controls the transmitter 204 to transmit a first maximum queuing delay more frequently than a second maximum queuing delay, e.g., maximum queuing delay 246 corresponding to transmission queue 1 228 is controlled to be transmitted more frequently than maximum queuing delay 250 corresponding to transmission queue N 230.
  • [0048]
    Backlog information generation module 224 generates information indicating an amount of data waiting to be transmitted, e.g., queue 1 backlog count information 248. Backlog information generation module 224 also uses queue backlog count information, e.g., queue 1 backlog count information 248, to generate a backlog report corresponding to backlog report information 262. Coding module 226 performs coding operations including jointly coding backlog information, e.g., frame counts of data to be transmitted, and delay information. For example, coding module 226 jointly codes 1st maximum queuing delay 246 and queue 1 backlog count information 248 into an uplink control information report corresponding to report information 264.
  • [0049]
    Data/information 216 includes one or more transmission queues (transmission queue 1 228, . . . , transmission queue N 230), queue statistics 232, information identifying packet(s) to be dropped 254, delay transmission rate information 256, information associating queues with types of traffic flows 258, delay report information 260, backlog report information 262, report information including jointly coded delay and backlog information 264, channel structure information 266 and control reports' format information 268.
  • [0050]
    The transmission queues (228, 230) store data to be transmitted by the wireless terminal. Transmission queue 1 228 includes a plurality of packets (packet 1 info 234, . . . , packet n info 236). Transmission queue N 230 includes a plurality of packets (packet 1 info 238, . . . , packet m info 240). Queue statistics 232 includes one or more sets of determined delay information for a corresponding transmission queue (determined delay information for transmission queue 1 242, . . . , determined delay information for transmission queue N 244). Determined delay information for transmission queue 1 242 includes a 1st maximum queuing delay 246 and transmission queue 1 backlog count information 248, e.g., frame counts of backlog for transmission queue 1. Determined delay information for transmission queue N 242 includes a Nth maximum queuing delay 250 and transmission queue N backlog count information 252, e.g., frame counts of backlog for transmission queue N.
  • [0051]
    1st maximum queuing delay 246 indicates a maximum amount of time a packet in the first transmission queue 228 has been waiting to be transmitted by the wireless terminal 200. Similarly, Nth maximum queuing delay 250 indicates a maximum amount of time a packet in the Nth transmission queue 230 has been waiting to be transmitted by the wireless terminal 200. Queue 1 backlog information 248 indicates an amount of backlog corresponding to transmission queue 1 228, e.g., a number of frames, e.g., number of MAC frames, of backlog. Queue N backlog information 252 indicates and amount of backlog corresponding to transmission queue N 230, e.g., a number of frames, e.g., number of MAC frames, of backlog.
  • [0052]
    In some embodiments, at least some different transmission queues correspond to different traffic flows. Information 258 associates queues with types of traffic. For example, in one exemplary embodiment, transmission queue 1 228 is associated with a voice traffic flow and transmission queue N 230 is associated with a non-voice traffic flow, e.g., a gaming or other interactive traffic flow.
  • [0053]
    Information identifying a packet to be dropped 254 is an output of queue management module 220 and is used to update a transmission queue, e.g., management module 220 updates transmission queue 1 228 based on information 254. Delay transmission rate information 256, e.g., scheduling information corresponding to communicating delay information control reports and/or backlog reports including delay information, is used by transmission control module 222 to control the communication of delay information corresponding to different queues.

    FIG. 10 is a drawing 1000 of exemplary uplink dedicated control channel (DCCH) segments in an exemplary uplink timing and frequency structure in an exemplary orthogonal frequency division multiplexing (OFDM) multiple access wireless communications system. The uplink dedicated control channel is used to send Dedicated Control Reports (DCR) from wireless terminals to base stations. Vertical axis 1002 plots logical uplink tone index while horizontal axis 1004 plots the uplink index of the halfslot within a beaconslot. In this example, an uplink tone block includes 113 logical uplink tones indexed (0, . . . 112); there are seven successive OFDM symbol transmission time periods within a halfslot, 2 additional OFDM symbol time periods followed by 16 successive half-slots within a superslot, and 8 successive superslots within a beacon slot. The first 9 OFDM symbol transmission time periods within a superslot are an access interval, and the dedicated control channel does not use the air link resources of the access interval.
  • [0112]
    The exemplary dedicated control channel is subdivided into 31 logical tones (uplink tone index 81 1006, uplink tone index 82 1008, . . . , uplink tone index 111 1010). Each logical uplink tone (81, . . . , 111) in the logical uplink frequency structure corresponds to a logical tone indexed with respect to the DCCH channel (0, . . . , 30).
  • [0113]
    For each tone in the dedicated control channel there are 40 segments in the beaconslot corresponding to forty columns (1012, 1014, 1016, 1018, 1020, 1022, . . . , 1024). The segment structure repeats on a beaconslot basis. For a given tone in the dedicated control channel there are 40 segments corresponding to a beaconslot 1028; each of the eight superslots of the beaconslot includes 5 successive segments for the given tone. For example, for first superslot 1026 of beaconslot 1028, corresponding to tone 0 of the DCCH, there are five indexed segments (segment [0][0], segment [0][1], segment [0][2], segment [0][3], segment [0][4]). Similarly, for first superslot 1026 of beaconslot 1028, corresponding to tone 1 of the DCCH, there are five indexed segments (segment [1][0], segment [1][1], segment [1][2], segment [1][3], segment [1][4]). Similarly, for first superslot 1026 of beaconslot 1028, corresponding to tone 30 of the DCCH, there are five indexed segments (segment [30][0], segment [30][1], segment [30][2], segment [30][3], segment [30][4]).
  • [0114]
    In this example each segment, e.g., segment [0][0], comprises one tone for 3 successive half-slots, e.g., representing an allocated uplink air link resource of 21 OFDM tone-symbols. In some embodiments, logical uplink tones are hopped to physical tones in accordance with an uplink tone hopping sequence such that the physical tone associated with a logical tone may be different for successive half-slots, but remains constant during a given half-slot.
  • [0115]
    Each logical tone of the dedicated control channel may be assigned by the base station to a different wireless terminal using the base station as its current point of attachment. For example, logical tone (1006, 1008, . . . , 1010) may be currently assigned to (WT A 1030, WT B 1032, . . . , WT N′ 1034), respectively.
  • [0116]
    Each uplink DCCH segment is used to transmit a set of Dedicated Control Channel Reports (DCRs). A list of exemplary DCRs is given in table 1100 of FIG. 11. First column 1102 of table 1100 describes abbreviated names used for each exemplary report. The name of each report ends with a number which specifies the number of bits of the DCR. Second column 1104 of table 1100 briefly describes each named report. In this exemplary embodiment, there are two type of Delay information reports DELAYA4 and DELAYB4. In addition, the flexible report, whose type is defined by report TYPE2 can be used to carry a DELAYA4 report or a DELAYB4 report in a corresponding BODY4 report. In addition, uplink request reports, e.g., ULRQST1, ULRQST3 and/or ULRQST4, are, in some embodiments, used to convey delay information.
  • [0117]
    FIG. 12 is a drawing 1299 illustrating an exemplary reporting format information in an exemplary beaconslot for a given DCCH tone, e.g., corresponding to a wireless terminal. In FIG. 12, each block (1200, 1201, 1202, 1203, 1204, 1205, 1206, 1207, 1208, 1209, 1210, 1211, 1212, 1213, 1214, 1215, 1216, 1217, 1218, 1219, 1220, 1221, 1222, 1223, 1224, 1225, 1226, 1227, 1228, 1229, 1230, 1231, 1232, 1233, 1234, 1235, 1236, 1237, 1238, 1239) represents one segment whose index s2 (0, . . . , 39) is shown above the block in regular region 1240. Each block, e.g., block 1200 represents segment 0, conveys 6 information bits; each block comprises 6 rows corresponding to the 6 bits in the segment, where the bits are listed from the most significant bit to the least significant bit downwards from the top row to the bottom row as shown in rectangular region 1234.
  • [0118]
    In this exemplary embodiment, delay information is conveyed by means of the flexible report and/or by means of one or more of the uplink request reports (ULRQST1, ULRQST3 and/or ULRQST4). In other embodiments, predetermined slots are allocated in the reporting structure, which are reserved for delay information reports. For example, one or more of the four bit designed report slots in the exemplary reporting structure of FIG. 12 may be replaced with a DELAY4 report. In some embodiments some predetermined slots are allocated to convey delay information corresponding to a first queue and some other predetermined slots are allocated to convey delay information corresponding to a second queue. In some such embodiments, the allocation may be such that the delay information corresponding to the first queue is transmitted at a different rate, e.g., a higher rate, than the delay information corresponding to the second queue. In some embodiments, the first and second queues correspond to different request groups. In some embodiments, communicated delay information and/or communicated backlog information represents aggregated information, e.g., corresponding to a plurality of transmission streams.

Column 1302 of table 1300 lists the 16 possible information bit patterns for the report, and column 1304 lists, for each of the possible bit patterns, maximum delay time information for a packet in a transmission queue which is conveyed by the report if that bit pattern is communicated. For example, bit pattern=0011 means that the maximum delay time is greater than 15 ms and less than or equal to 20 ms.
  • [0120]
    FIG. 14 is a drawing of a table 1400 describing an exemplary format of exemplary 4 bit delay report (DELAYB4). Column 1402 of table 1400 lists the 16 possible information bit patterns for the report, and column 1404 lists, for each of the possible bit patterns, minimum delay to packet discard deadline information for a packet in a transmission queue which is conveyed by the report if that bit pattern is communicated. For example, bit pattern=0101 means that the minimum delay to transmission deadline is greater than 25 ms and less than or equal to 30 ms.
  • [0121]
    In some embodiments, at least some delay information reporting formats accommodate reporting delay information corresponding to a plurality of different queues. For example, different delay information can be, and sometimes is, reported corresponding to different queues or different groupings of data to be transmitted, e.g., a first delay associated with queued voice traffic and a second delay associated with other time sensitive traffic.
  • [0122]
    FIG. 15 is a drawing of a table 1500 describing an exemplary flexible report corresponding to TYPE2 and BODY4. In the flexible report, the wireless terminal selects which type of report to communicate in the allocated flexible report slot. In this exemplary embodiment, the selection for the flexible report includes the option to report delay information, e.g., using either DELAYA4 or DELAYB4 format. The wireless terminals communicates its selection of report type in a TYPE2 report and a corresponding selected report in the BODY4 report of the allocated flexible report slot. Column 1502 of table 1500 lists the 4 possible information bit patterns for the TYPE2 report, and column 1504 lists, for each of the possible bit patterns, the report to be carried in the BODY4 report position if that bit pattern is communicated. For example, if bit pattern=11 is communicated in the TYPE2 report slot, a DELAYB4 report is to be communicated in the corresponding BODY4 slot.
  • [0123]
    In various embodiments a wireless terminal provides delay information for uplink traffic backlog. In order to enable a base station (BS) to provide adequate quality of service (Qos) in the uplink, the wireless terminal (WT), in some embodiments, periodically transmits control information to the BS. For example, this control information includes, in some embodiments, of one or more of the following: amount of backlog, i.e., queue length, at the WT, power availability at the WT and information pertaining to interference management, such as, e.g., path loss ratio or beacon ratio reports. However, a scheduler, in addition to the information listed above, could also beneficially use information related to delay in order to make timely decisions when scheduling delay-sensitive traffic. Examples of such delay-sensitive traffic include voice, gaming and other interactive applications.
  • [0124]
    Delay information can, in some embodiments, take one of the following two forms. (1) The maximum queuing delay across each of the packets in the WT's queue. In the case where the WT has multiple queues, each for a different traffic flow, the maximum could, in some embodiments, be computed across the packets in one or more queues. Note that each of these queues could represent traffic with different Qos requirements. Typically, this maximum would be calculated for packets that belong to delay-sensitive traffic flows. (2) The minimum time remaining to scheduling deadline or packet discard deadline across each of the packets in the WT's queue. Once again, if the WT has multiple queues, each for a different traffic flow, the minimum could, in some embodiments, be calculated for packets with latency or delay constraints.
  • [0125]
    The delay information itself can be reported in several ways. In an exemplary system, e.g., an exemplary OFDM wireless communications system, for example, the delay information can be transmitted using request dictionaries. An exemplary request dictionary, in some exemplary embodiment, includes a plurality of different bit size request reports, e.g., a 1-bit, a 3-bit and a 4-bit request report. Each of these reports is used to provide information pertaining to the backlog across traffic flows at the WT.
  • [0126]
    The 1-bit report, for example, can be used to simply indicate the presence of traffic with time remaining to deadline less than T ms. For example, T could equal 20 ms. The remaining report types are, e.g., used to provide more detailed backlog information, such as time remaining to deadline and total backlog, for the traffic flows. More precisely, each of these reports could be used to convey one or both deadline and total backlog information. This is illustrated below using several examples.
  • [0127]
    Let D denote the minimum time remaining, in milliseconds, to the scheduling deadline for each of the packets in the WT's queues. Let N denote the total backlog at the WT, e.g., a MAC frame count. Using these notations, the 3-bit and 4-bit reports are as follows.
  • [0128]
    In one illustrative example of a request dictionary, Dictionary A as represented by Table 1700 of FIG. 17 and Table 1800 of FIG. 18, the WT only transmits total backlog information in the 3-bit report. The 4-bit report, on the other hand is used to transmit either delay information or total backlog information. In this exemplary embodiment, the 3-bit report depends on two control factors, y and z, which, in turn, depend on a previous power report, e.g., the last reported uplink DCCH backoff report, x, and a previous interference report, e.g., the last reported beacon ratio report, bactual. The WT then calculates b, the “adjusted generic beacon ratio”, to be equal to bactual—BEACON_RATIO_OFFSET. Finally, let Rmax be the maximum rate option that the WT can support, and Nmax be the number of MAC frames corresponding to the rate option. An example of determining exemplary control factors is shown in Table 1600. In Table 1600, first column 1602 lists various test conditions; second column 1604 lists corresponding values for control factor y for each condition; third column 1606 lists corresponding values for control factor z corresponding for each condition. In Table 1600, given x and b, the of y and z should be taken as those from the first row, proceeding from top to bottom, for which the condition in the first column is satisfied.
  • [0129]
    In the 4-bit report of the format of table 1800 of FIG. 18, the WT transmits the time remaining to deadline information D whenever D<Tmax. For example, Tmax=100 ms. Otherwise, it transmits backlog information. Define Δ = N - N min y ,
    where Nmin is determined based on the value of N at the time of the last 3-bit report, using Table 1700 of FIG. 17.
  • [0130]
    In yet another illustrative example of a request dictionary, Dictionary B represented by table 1900 of FIG. 19 and Table 2000 of FIG. 20, the WT transmits delay information in the 3-bit report using the format of table 1900 of FIG. 19. The 4-bit report with format of table 2000 of FIG. 20, on the other hand is used to transmit total backlog information. The control factors y and z used for the 4-bit report are determined from DCCH backoffs and adjusted beacon ratio report in a manner described above with regard to Table 1600 of FIG. 16.
  • [0131]
    In yet another illustrative example of a request dictionary, Dictionary C represented by table 2100 of FIG. 21 and table 2200 of FIG. 22, the WT—as in Dictionary B above—transmits delay information in the 3-bit report using the format of table 2100 of FIG. 21. However, in the 4-bit report with the format of table 2200 of FIG. 22, the WT can transmit either the total backlog information or the number of frames, ND, with time remaining to deadline<=Dmax. Dmax, for example could equal 50 ms. In yet another example, Dmax could equal Tmax.
  • [0132]
    The examples above illustrate that several request dictionaries can be constructed where request reports, e.g., the 3-bit and/or 4-bit request reports, contain one or more of the following: (1) delay information, (2) total backlog information, (3) backlog information for some of the traffic flows, (4) total backlog with time remaining to deadline less than some value ND, and (5) a refinement of the request information carried in a previous report, e.g., the previous 3-bit request report, 4-bit request report or the previous request report.
  • [0133]
    In an exemplary wireless communications system, e.g., an exemplary OFDM system, in addition to or in place of providing delay information to the BS using request reports, e.g., request reports as part of request dictionaries, as illustrated above, the WT could transmit delay information using separate delay information reports. In some such embodiments, a flexible report, e.g., a flexible dedicated control channel (DCCH) report, could be used. With the flexible report, the wireless terminal selects the type of report to send in the reporting opportunity allowed to the flexible report. For example, an exemplary 4-bit flexible report could, contain one or more of the following: (1) delay information, (2) total backlog with time remaining to deadline less than some value ND, and (3) a refinement of the request information carried in a previous report, e.g., the previous 3-bit or 4-bit UL-RQST report or the previous UL-RQST report.
  • [0134]
    Note that the bit sizes for the request reports in the examples above, e.g., 1 bit, 3 bit, 4 bit, are exemplary, and in other embodiments, different bit size request reports may be used. FIGS. 12 and 13 provide two examples of exemplary delay information report formats. FIG. 15 describes a flexible report format that may be used to convey delay information during some times and is used to carry other information during other times.
  • [0135]
    Another exemplary embodiment shall be described which uses three different bit size request reports for uplink traffic, ULRQST1, ULRQST3 and ULRQST4, and which supports the communication of delay information.
  • [0136]
    The WT uses an ULRQST1, ULRQST3 or ULRQST4 to report the status of the MAC frame queues at the WT transmitter.
  • [0137]
    The WT transmitter maintains MAC frame queues, which buffers the MAC frames to be transmitted over the link. The MAC frames are converted from the LLC frames, which are constructed from packets of upper layer protocols. Any packet shall belong to one of 16 streams. If the packet belongs to one stream, then all the MAC frames of that packet also belong to that stream.
  • [0138]
    The WT reports the number of MAC frames in the 16 streams that the WT may intend to transmit. In the ARQ protocol, those MAC frames shall be those marked as “new” or “to be retransmitted”. The WT should maintain two vectors of sixteen elements N[0:15] and D[0:15], and shall maintain three scalars NT, ND, and Dmin: for k=0:15, N[k] represents the number of MAC frames that the WT intends to transmit in stream k, while D[k] represents the minimum time remaining to transmission deadline for the packets that the WT intends to transmit in stream k. Furthermore,
      • Dmin=min[k=0:15]D[k],
      • NT=N[0]+N[1]+N[2]+ . . . +N[15], and
      • ND=number of MAC frames with time remaining to transmission deadline≦TM.
  • [0142]
    For example, TM=20 ms. The WT should report information about NT, ND, and Dmin to the base station sector so that the base station sector can utilize the information in an uplink (UL) scheduling algorithm to determine the assignment of uplink traffic channel (UL.TCH) segments.
  • [0143]
    The WT uses an ULRQST1 to report ND according to Table 2300 of FIG. 23.
  • [0144]
    Let D denote the minimum time remaining, in milliseconds, to the scheduling deadline for all packets in the WT's queues. Let N denote the total backlog at the WT. Using these notations, the 3-bit and 4-bit reports are as follows.
  • [0145]
    The WT uses ULRQST3 or ULRQST4 to report one or more of NT, ND, or Dmin according to a request dictionary. A request dictionary is identified by a request dictionary (RD) reference number. At a given time, the WT uses only one request dictionary. When the WT just enters the ACTIVE state, the WT uses the default request dictionary. To change the request dictionary, the WT and the base station sector uses an upper layer configuration protocol. When the WT migrates from the ON state to the HOLD state, the WT keeps the last request dictionary used in the ON state so that when the WT migrates from the HOLD state on the ON state later, the WT continues use the same request dictionary until the request dictionary is explicitly changed. However, if the WT leaves the ACTIVE state, then the memory of the last request dictionary used shall be cleared.
  • [0146]
    The request dictionaries show that any given instance of a ULRQST3 or ULRQST4 report may not completely contain the actual values of NT, ND, or Dmin. A report is in effect a quantized version of the actual values of NT, ND, or Dmin. A general guideline is that the WT should send a report to minimize the discrepancy between the reported and actual values of NT, ND, or Dmin. However, the WT has the flexibility of determining a report to benefit the WT the most. For example, when the WT is using request dictionary 0, the WT may use ULRQST4 to report NT in some cases and ND in others. Furthermore, in instances where the WT reports NT, it may not automatically imply that ND=0.
  • [0147]
    To determine ULRQST3 or ULRQST4, the WT first calculates the following two parameters, y and z, e.g., in accordance with table 1600 of FIG. 16 and then uses one of the following dictionaries. Denote by x the value (in dB) of the most recent ULTXBKF5 report, and by b0 the value (in dB) of the most recent generic DLBNR4 report. An exemplary range for x is 6.5 dB to 40 dB. An exemplary range for b0 is −3 dB to 26 dB. The WT further determines an adjusted generic DLBNR4 report value b as follows: b=b0—ulTCHrateFlashAssignmentOffset, where minus is defined in the dB sense. Given x and b, the WT determines y and z as those from the first row in table 1600 of FIG. 16 for which the condition in the first column is satisfied. For example, if x=17 and b=1, then z=min(3, Nmax) and y=1. Denote Rmax the highest rate option that the WT can support, and Nmax the number of MAC frames that can transmitted in that rate option.
