Abstract
Embodiments of systems and methods for group resource allocation are generally described herein. Other embodiments may be described and claimed.
Claims13
A method for group resource allocation (GRA), comprising:
- determining, by circuitry, available modulation and coding schemes (MCS) and packet sizes;
- computing a resource size matrix;
- choosing effective combinations of MCS and packet sizes from the resource size matrix;
- defining a first parameter set using the effective combinations of MCS and packet sizes;
- forming a first group of users that use the first parameter set, the first group of users formed based at least in part on parameters specific to the first group of users;
- forming a second group of users that use the first parameter set;
- generating a first subframe group in a first frame having a first group identification (ID) number for the first group, wherein the first subframe group is assigned the first parameter set;
- generating a second subframe group in the first frame having a second group ID number for the second group, wherein the second subframe group is assigned the first parameter set;
- determining a reporting frequency for hierarchical reporting of a first channel quality indicator (CQI) value, wherein the reporting frequency is based at least in part on a periodicity of forming groups of users;
- receiving first CQI information over a first node of a hierarchical tree, the first CQI information to comprise the first CQI value and a node value of the first node;
- determining a set of subbands of a second frame;
- and
- receiving second CQI information over a best-m subbands of the set of subbands via best-m reporting that is periodically triggered, the second CQI information to comprise a second CQI value, a reporting frequency of the best-m reporting to be less than the reporting frequency of the hierarchal reporting.

A method of forming a frame using group resource allocation (GRA) to provide resource allocations to multiple users per group, comprising:
- forming, by circuitry, a first group of users that use a first parameter set, the first group of users formed based at least in part on parameters specific to the first group of users, the first parameter set to include a multiple input multiple output (MIMO) mode parameter;
- forming a second group of users that use the first parameter set;
- generating a first group in the frame having a first group identification (ID) number for the first group, wherein the first group is assigned the first parameter set;
- generating a second group in the frame having a second group ID number for the second group, wherein the second group is assigned the first parameter set;
- receiving channel quality indicator (CQI) feedback for the frame via hierarchal reporting, wherein the reporting frequency is based at least in part on a periodicity of forming groups of users;
- and
- receiving CQI feedback for a second frame via best-m reporting that is periodically triggered, a reporting frequency of the best-m reporting to be less than a reporting frequency of the hierarchal reporting.

A method for providing channel quality indicator (CQI) feedback for a station (STA), comprising:
- forming a first group of users that use the first parameter set, the first group of users formed based at least in part on parameters specific to the first group of users;
- forming a second group of users that use the first parameter set;
- establishing a reporting frequency for hierarchal CQI feedback reporting, wherein the reporting frequency is based at least in part on a periodicity of forming groups of users;
- determining a first node in a hierarchical tree to report first CQI feedback via the hierarchical CQI feedback reporting;
- determining a subband that correlates with the first node;
- associating with the first group of users in the subband;
- reporting the first CQI feedback in a first frame, the first CQI feedback to comprise a CQI value and a node value of the first node;
- and
- reporting second CQI feedback in a second frame using best-m CQI feedback reporting that is periodically triggered, a reporting frequency of the best-m CQI feedback reporting to be less than the reporting frequency of the hierarchical CQI feedback reporting.
