Enhancing PRAW Signaling with Modified RPS_IE for Efficient Wireless Communication

This paper by Young Hoon Kwon from Huawei discusses enhancements to the PRAW (Periodic Resource Allocation for Wireless) signaling method within the RPS_IE (Restricted Access Window Signaling). By introducing a new indication bit for PRAW in the RPS_IE, the paper outlines how to allocate resources for scheduled active polling STAs without interference. The proposed modifications aim to optimize resource allocation, duration, and specific information for non-TIM users during PRAW periods, ultimately improving overall channel access efficiency.

  4. Background Young Hoon Kwon, Huawei • TGah accepted concept of PRAW [1]: • AP allocates resource for group of scheduled active polling STAs and indicates the resource allocation once in a long while. • Not indicated in every short beacon frame (E.g., once in every long beacon frame) • Once PRAW is setup, AP allocates the resource periodically to a group of scheduled active polling STAs. • Allocated resource for PRAW will not be changed until updated PRAW information is broadcasted. • Resource for scheduled active polling STAs can be allocated within the PRAW duration. • Whenever scheduled active polling STA has data packet to send, it wakes up at its designated slot within the PRAW and send the packet after basic CCA. • TIM STAs are not allowed to access the channel during this window. • Within PRAW, each STA follows EDCA based channel access scheme. • In this contribution, we’d like to define PRAW signaling method.

  6. PRAW Signaling • Propose to modify current RPS_IE to include PRAW Signaling. • For each RAW indication, add 1 bit for “PRAW indication”. • If PRAW indication = 0, it means this RAW indication is for a normal RAW definition. • If PRAW indication is set, • it includes PRAW specific information such as • Periodicity (TBD bits): Period of PRAW occurrence in the unit of short beacon interval • Start Offset (TBD bits): Offset value to a short beacon frame that the first window of the PRAW appears from a reference point. (How to set a reference point and unit is TBD) • Also, Option and Slot definition subfields can be removed if PRAW indication is set. • As PRAW broadcasting is for TIM STAs who are not allowed to attend during PRAW duration, detailed slot definition within PRAW is not informative. • RAW group, RAW start time, and RAW duration are included. • RAW group: Indicates Non-TIM user group that may be scheduled in the PRAW. • RAW start time: Indicates start time of PRAW with respect to the end of beacon transmission. • RAW duration: Indicates duration of PRAW.
