WInnForum Recognized CBRS Grouping Information
Document WINNF-SSC-0010
Version 4.2.0
30 June 2021
This document specifies Citizens Broadband Radio Service (CBRS) Grouping Information supported by the standards, e.g. [n.6][n.7], developed by the Wireless Innovation Forum (WInnForum) Spectrum Sharing Committee (SSC) for the CBRS band.
This document specifies CBRS Grouping Information. There are two types of Grouping Information:
This document only contains Group types and IDs that have been defined by the WInnForum or Third-Party proprietary Group types and/or IDs that have been registered with the WInnForum via a Grouping Information registration request [n.1]. Third-party proprietary Group types that are not registered in this document can be used for operation but groupType values of such Groups must be a string prefixed with CBRS Vendor/Admin IDs registered in WINNF-SSC-0013 [n.11].
The entity or individual that defines a particular Grouping Information is responsible for fully defining the Grouping Information such that implementation can be accomplished [n.1].
The following referenced documents are necessary for the application of the present document.
CBRS band: The 3550-3700 MHz Citizens Broadband Radio Service band.
Citizens Broadband Radio Service Device (CBSD): Fixed Stations, or networks of such stations, that operate on a Priority Access or General Authorized Access basis in the Citizens Broadband Radio Service band.
Domain Proxy (DP): The DP is a logical entity that can represent one or more CBSD(s) to the SAS. The DP presents a consistent and secure interface to the SAS that can convey all messages pertaining to the SAS-CBSD interface for client CBSDs.
Spectrum Access System (SAS): A system that authorizes and manages use of spectrum for the Citizens Broadband Radio Service in accordance with subpart F.
CBRS Citizens Broadband Radio Service
CBSD Citizens Broadband Radio Service Device
DP Domain Proxy
SAS Spectrum Access System
This document is applicable to the Release 2 feature "Enhanced CBSD Group Handling" specified in [n.6] and [n.7].
The GroupParam JSON object is used to communicate grouping information from the CBSD/DP to SAS and is defined in section 8.2.8 of WINNF-TS-3002 [n.6].
Coexistence Group (CxG) has been defined by the WInnForum in WINNF-TS-0112 [n.4]. This Group type identifies a Group of CBSDs that coordinate their own interference within the group according to a common interference management policy [n.4].
CBRS Alliance Coexistence Group (CxG) and its common interference management policy has been defined by CBRS Alliance in CBRSA-TS-2001 [n.5].
The groupType value is "COEXISTENCE_GROUP".
The groupId value is "CBRS_ALLIANCE".
See details of GroupInfo object definition in CBRSA-TS-2001 [n.5].
Principal-Subordinate SFG is defined in Annex 2 of WINNF-TS-1001 [n.8].
The groupType value is "PRINCIPAL_SUBORDINATE_SFG".
The groupId values for Principal-Subordinate SFG are not registered with WInnForum and are not guaranteed by WInnForum to be unique. The CBSD Users are encouraged to pre-coordinate with their Managing SAS Administrator offline to ensure uniqueness of the groupId values. The groupId value is assigned when the Managing SAS accepts the groupId value in response to the membership indication by the first member of the planned Group. The CBSD User can specify its planned groupId value in the GroupParam object sent by its CBSDs to its Managing SAS, and the Managing SAS will accept the groupId value if the uniqueness of the groupId value is ensured.
The GroupInfo object is defined in Table 1.
Table 1: GroupInfo Object Definition
| Parameter | Presence | Description |
|---|---|---|
NAME: cbsdType DATA TYPE: string | Optional | This parameter represents a type of CBSD in this Group. Acceptable values are: • "PRINCIPAL" • "SUBORDINATE" The default value of this parameter is "SUBORDINATE". |
Interdependent SFG is defined in Annex 3 of WINNF-TS-1001 [n.8].
The groupType value is "INTERDEPENDENT_SFG".
The groupId values are not registered with WInnForum and are not guaranteed by WInnForum to be unique. The CBSD Users are encouraged to pre-coordinate with their Managing SAS Administrator offline to ensure uniqueness of the groupId values. The groupId value is assigned when the Managing SAS accepts the groupId value in response to the membership indication by the first member of the planned Group. The CBSD User can specify its planned groupId value in the GroupParam object sent by its CBSDs to its Managing SAS, and the Managing SAS will accept the groupId value if the uniqueness of the groupId value is ensured.
The GroupInfo object is not defined for this type of SFG.
Separable SFG is defined in Annex 4 of WINNF-TS-1001 [n.8].
The groupType value is "SEPARABLE_SFG".
The groupId values are not registered with WInnForum and are not guaranteed by WInnForum to be unique. The CBSD Users are encouraged to pre-coordinate with their Managing SAS Administrator offline to ensure uniqueness of the groupId values. The groupId value is assigned when the Managing SAS accepts the groupId value in response to the membership indication by the first member of the planned Group. The CBSD User can specify its planned groupId value in the GroupParam object sent by its CBSDs to its Managing SAS, and the Managing SAS will accept the groupId value if the uniqueness of the groupId value is ensured.
The GroupInfo object is not defined for this type of SFG.
Spectrum Reuse Group has been defined per a Grouping Information registration request [n.1].
This Group type identifies a Group of CBSDs operated by a CBSD User or a group of CBSD Users where the CBSDs can use the same spectrum. SAS is not involved in the interference management among the members of this group.
6.4.1.1 groupType
The groupType value is "SPECTRUM_REUSE".
6.4.1.2 groupId
The groupId values are not registered with WInnForum and are not guaranteed by WInnForum to be unique. The CBSD Users or the representative of the group of the CBSD Users are encouraged to precoordinate with their Managing SAS Administrator offline to ensure uniqueness of the groupId values. The groupId value is assigned when the Managing SAS accepts the groupId value in response to the membership indication by the first member of the Group. The CBSD User can specify its planned groupId value in the GroupParam object sent by its CBSDs to its Managing SAS, and the Managing SAS will accept the groupId value if the uniqueness of the groupId value is ensured.
The GroupInfo object for SRG is not defined in this version of this document.
Passive DAS is defined in Annex 7 of WINNF-TS-1001 [n.8].
This Group type identifies a Group of CBSDs belonging to the same Passive DAS chain of antennas (Transmission Points) fed from a unique Radio Unit.
6.5.1.1 groupType
The groupType value is "PASSIVE_DAS".
6.5.1.2 groupId
The groupId is a string of
The GroupInfo object for Passive DAS is not defined in this version of this document.
The GroupConfig JSON object is used to communicate grouping configuration from SAS to the CBSD/DP and it is defined in Table 16 of WINNF-TS-3002 [n.6]. The GroupConfig object includes the groupConfigInfo parameter (
DATA TYPE: GroupConfigInfo object) containing details of the grouping configuration.
GroupConfigInfo object definition for CBRS Alliance CxG is defined in Table 2.
Table 2: GroupConfigInfo Object Definition

GroupConfigInfo object definition for Independent SFG is not defined in this version of this document.
GroupConfigInfo object definition for Separable SFG is not defined in this version of this document.
GroupConfigInfo object definition for SRG is not defined in this version of this document.
GroupConfigInfo object definition for Passive DAS is not defined in this version of this document.
GroupInfoResponse object, which is defined as part of GroupConfig object in WINNF-TS-3002 [n.6], can be used to communicate errors in GroupInfo object from a SAS to a CBSD/DP. The GroupInfoResponse object includes groupInfoResponseCode parameter indicating a type of errors in GroupInfo object.
In addition to common acceptable values of the groupInfoResponseCode parameter for any Group type/ID defined in WINNF-TS-3002 [n.6], the organization, entity or individual that specifies the groupType and/or groupId may additionally define the acceptable values of this parameter specific to its Group.
