During a random access communication opportunity (12), user equipment (20) utilizes either or both of an adaptive modulation and coding-based communication protocol (26) and an HARQ-based communication protocol (27) to achieve improved performance. This can avoid the need to establish dedicated channels (13) to support the required communications. In one embodiment, a plurality of adaptive modulation and coding-based communication protocols are provided with a given protocol being selected as a function of one or more governing criteria. For example, the protocol can be selected as a function of a quality condition of the communication path, as a function of a memory buffer, and so forth.
