摘要： Apparatus, and an associated method, by which to select the number of random access channels to form a portion of a frame in a frame-formatted communication system. The number of random access channels allocated to form a portion of a frame is made responsive to quantitative determination of the likely need to communicate thereupon during the frame. In one implementation, selection is made of the number of random access channels to form portions of a frame defined in a HIPERLAN/2 system.

摘要： Apparatus, and an associated method, by which to select the size of a contention window within which to transmit a packet of data upon a random access channel in a multi-user scheme. The number of time slots allocated to form random access channels in a frame is selectably variable in a dynamic manner. Advantage is made of the dynamic allocation of random access channels to select the size of the contention window. Operation is advantageously implemented in a mobile terminal operable in a wireless LAN (local area network), such as that set forth in the BRAN (broadband access network) promulgated by the ETSI.

摘要： Apparatuses and methods are disclosed herein for implementing dormant mode with paging in a WLAN. Power savings in the computing device and reduction in traffic across the network are achieved by requiring a computing device to inform the WLAN of its location only when it crosses a paging area boundary or is to receive IP traffic. Dormant mode with paging is implemented in a protocol that supports dormant functionality and paging functionality but does not itself provide methods or standards for implementing such functionality, such as the IEEE 802.11. The methods and apparatuses disclosed herein provide the methods needed to implement dormant mode with paging in such a protocol. Generally, the methods and apparatuses for implementing dormant mode with paging basically include (1) establishing paging areas; (2) communicating access group information to a computing device; and (3) locating a computing device.
