Embodiment Construction

[0014] As used herein the word "a" means one or more and the word "plurality" means two or more.

[0015] As used herein, the word "deterministic" means having a time evolution that can be predicted with substantial accuracy. For example, a deterministic time interval is one whose beginning and end can be predicted with substantially precise accuracy.

[0016] In the following detailed description, for purposes of explanation rather than limitation, representative embodiments disclosing specific details are set forth in order to provide a thorough understanding of the present teachings. However, other embodiments without the specific details disclosed herein will be apparent to those skilled in the art having the benefit of this disclosure. Moreover, descriptions of well-known devices, methods, systems, and protocols may be omitted so as not to obscure the description of representative embodiments. However, such devices, methods, systems and protocols within the purview of t...

Abstract

A wireless system (100) includes at least one power-save wireless station (PS STA)(102). A method of wireless includes allocating deterministic time intervals (206,207) to the PS-STAs.

Description

Background technique [0001] Significant advances in wireless communication technology have made the wireless medium a viable alternative to wired solutions. Accordingly, the use of wireless connections for data and voice communications continues to grow. These devices include: mobile phones, portable computers in a wireless network (eg, wireless local area network (WLAN)), stationary computers in a wireless network, portable handsets, and the like. [0002] The constant challenge in standards such as IEEE 802.11 and its derivatives is to provide quality of service (QoS) guarantees for real-time and critical applications, such as voice and medical applications, while consuming specific mobile wireless stations (STAs). power is minimized. The IEEE 802.11e amendment to the IEEE 802.11 standard has recently been passed. IEEE 802.11e defines the Hybrid Coordination Function (HCF) Controlled Channel Access (HCCA) mode of operation to support parameterized QoS through a Hybrid Coo...
