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 application 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 selecting between a plurality of dictionaries. BACKGROUND [0003] Wireless terminals in a wireless communications system supporting uplink traffic, e.g., uplink user data, from the wireless terminals to the base stations need to use uplink air link resources to both communicate control information and user data. In multiple access wireless communications systems, typically, multiple wireless terminals using a base station attachment point are competing for valuable uplink air link resources, e.g., uplink traffic channel air link resources. One approach to partitioning uplink traffic channel resources is for the wireless terminals to send resource requests to their current base station attachment point, for the base station to consider the competing requests and allocate the resources, e.g., uplink traffic channel segments, in accordance with its scheduling rules. [0004] Individual wireless terminals can have different needs for uplink traffic channel resources at different times, e.g., depending on a variety of factors such as the type(s) of user data to be communicated, e.g., voice, image data, Web browser information, data files, etc., latency requirements, predetermined data groupings, and/or priority levels. [0005] A single fixed interpretation uplink traffic channel request report format used for a particular type of uplink request report, understood by the base station and the wireless terminals, and used uniformly in the system, although simple to implement, is not well suited to efficiently communicate a wide range of uplink traffic channel request information. By increasing the bit size of the fixed interpretation information report to a relatively large number, the range of reporting possibilities increases, but this is achieved at the expense of valuable air link resources which could have otherwise been devoted to user traffic. [0006] Based on the above discussion, it should be appreciated that there is a need for methods and apparatus for reporting information in an efficient manner. It would be desirable if at least some efficient reporting methods could be devised. It would also be desirable if at least some methods could be used to implement an uplink traffic channel resource request structure which is accommodating to a wide range of wireless terminal operating conditions, types of wireless terminals and/or blend of applications. It should also be appreciated that for some systems there is a need for at least some methods and apparatus which can efficiently communicate the varying needs of individual wireless terminals for uplink traffic channel resources. Methods and apparatus which achieve reporting diversity while accommodating small information report size, e.g., of 3 or 4 bits, would be beneficial. Methods and apparatus which support the maintenance of multiple uplink traffic channel request groups, multiple types of traffic flows, communication of backlog information and/or communication of delay information would also be beneficial. Methods and apparatus which provide for intelligent selection between various available reporting format alternatives would also be desirable. Well suited selection of a reporting format alternative could result in more efficient scheduling, reduced interference, a better quality of service, and/or higher throughput. SUMMARY [0007] Various embodiments are directed to methods and apparatus for implementing alternative report definitions sets and/or selecting between the alternative report definitions sets when communicating information over a wireless communication channel. For example, each report definition set may include information defining bit mappings for one or more fixed bit size control reports such as for a set of fixed bit size uplink transmission backlog reports. Different report definition sets are advantageously structured to accommodate different reporting requirements. A report definition set is selected, e.g., on a per wireless terminal connection basis, to match current reporting needs thus providing for more efficient reporting than would be otherwise possible if only one report definition set was implemented to be used universally throughout the communications system. [0008] An exemplary method of operating a communications device, in accordance with various embodiments includes: selecting a report definition set to be used in communicating backlog information from a plurality of alternative report definition sets, alternative report definition sets providing alternative mappings of report bits to information to be communicated for at least one report type: and performing one of: i) generating a report using an information to report bit mapping specified by the selected report definition set and ii) processing a received report to recover information included in the received report in accordance with the information to report bit mapping specified by the selected report definition set. In some such embodiments the method further includes identifying active traffic flows; and the selection of a report definition set is performed as a function of traffic flow information corresponding to the identified active traffic flows. For example, the traffic flow information may include one of more of the following: i) information characterizing the mixture of active traffic flows with respect to the presence or lack thereof of best effort traffic flows and/or latency constrained traffic flows, ii) information characterizing the mixture of active traffic flows with respect to different types of latency constrained traffic flows, e.g., voice vs gaming; iii) information identifying the number of distinct quality of service profiles present in the identified active traffic flows, and iv) information identifying a number of request grouping upon which backlog is to reported. [0009] An exemplary communications device, in accordance with various embodiments, includes: a report definition set selection module for selecting a report definition set to be used in communicating backlog information from a plurality of alternative report definition sets, alternative report definition sets providing alternative mappings of report bits to information to be communicated for at least one report type; and at least one of: i) a report generation module for generating a report using an information to report bit mapping specified by the selected report definition set; and ii) a report processing module for processing a received report to recover information include in the received report in accordance with the information to report bit mapping specified by the selected report definition set. In some such embodiments, the communications device further includes a traffic monitoring module for identifying active traffic flows; and the selection module performs said selection as a function of traffic flow information corresponding to the identified active traffic flows. [0010] In one exemplary embodiment, the alternative report definition sets corresponds to uplink request report dictionaries defining bit mappings for uplink request reports which communicate backlog information and/or delay information, e.g., in a dedicated control channel reporting structure. The communications device, in some embodiments, is a base station which performs the selection of the report definition set and subsequently processes a received report from a wireless terminal which is in accordance with the selected report definition set. Alternatively, in some embodiments, the communications device is a wireless terminal which performs the selection of the report definition sets and generates reports to be transmitted in accordance with the selected report definition set. [0011] While various embodiments have been discussed in the summary above, it should be appreciated that not necessarily all embodiments include the same features and some of the features described above are not necessary but can be desirable in some embodiments. Numerous additional features, embodiments and benefits of the present invention are discussed in the detailed description which follows.
