Re: [STDS-802-11-TGM] CID 3078 -- Definition of MCS and Basic Rate Set.



--- This message came from the IEEE 802.11 Task Group M Technical Reflector ---
Jon,
      thank you for the email.

Two items regarding your proposed definition:
1) I think you can lose an "of" in the initial sentence: "The set of MCSs that all STAs in a BSS are capable, or have signaled that they are capable, of receiving and transmitting.
2) The penultimate word "Operation" should be "operation".

Kind regards

Stephen

Greetings,
Next week we have on the agenda time to discuss

CID 3078
Comment:
The definition of basic modulation and coding scheme set contains the phrase "transmitting at all MCSs in the basic MCS set" which is confusing.

Proposed Change:
Rephrase as "transmitting using all MCSs in the basic MCS set"

From the November 15, 2022 Minutes:

2.8.7          CID 3078 (GEN)

2.8.7.1    Review Comment

2.8.7.2    Change “at” for “using”

2.8.7.3    Review context.

2.8.7.4    Discussion on what should be in a definition or not.  Requirements should not be put in the definition.  Suggestion to delete last line.

2.8.7.5    Discussion on alternate definition, and the definitive definition would be better.

2.8.7.5.1           E.g. basic MCS set: <something like>: The set of MCSs that all STAs in a BSS are capable of, or have signaled that they are capable of, receiving and transmitting.

2.8.7.6    The first two sentences may need to be removed also.

2.8.7.7    Assign to Jon ROSDAHL and Mark CID as “More work Required”.

2.8.7.8    Assign Agenda time in January.

2.8.7.9    Note that this is a similar change at line 30 as well. ... similar change for "basic rate set" at line 30

2.8.7.10 Discuss on the reflector as well.


From D2.1 Page 205.11

basic modulation and coding scheme (MCS) set: A set of MCSs designated by the station (STA) that started the basic service set (BSS) and fixed for the lifetime of the BSS. The basic MCS set is typically advertised in the element(s) (#1031)that contains the physical layer (PHY) operation parameters (among others), e.g., high throughput (HT) and very high throughput (VHT) Operation elements. All STAs in a BSS are capable of, or have signaled(#2256) that they are capable of, receiving and transmitting at all MCSs in the basic MCS set.

 
From D2.1 Page 205.22
basic rate set: A set of data rates designated by the station (STA) that started the basic service set (BSS) and fixed for the lifetime of the BSS. The basic rate set is advertised in the Supported Rates and BSS Membership Selectors element and, if present, the Extended Supported Rates and BSS Membership Selectors element. All STAs in a BSS are capable of, or have signaled that they are capable of, receiving and transmitting at all rates in the basic rate set.

Feedback is welcome,
We are scheduled to discuss on January 16th PM2.
